Pennsylvania — Corporate Income / Franchise Tax

Pennsylvania imposes an excise tax on corporations for the privilege of doing business in, carrying on activities in, owning or employing property or capital in, or having substantial nexus with the Commonwealth. Both domestic corporations (incorporated in Pennsylvania) and foreign corporations (incorporated outside Pennsylvania) are subject to the tax when they meet any of these conditions. Any entity classified as a corporation for federal income tax purposes is treated as a corporation for Pennsylvania purposes.

Entities subject to the bank and trust companies shares tax, gross premiums tax, mutual thrift tax, or title insurance company shares tax are exempt from corporate net income tax. Pennsylvania S corporations that have made a valid Pennsylvania S election are generally not subject to corporate net income tax, except on net recognized built-in gains. Pennsylvania does not automatically recognize federal S corporation elections; a separate state election is required for pass-through treatment.

All corporations incorporated in Pennsylvania must file annual reports even if no business activity was conducted during the taxable period. Out-of-state corporations with nexus—including economic nexus—must also file even without physical presence in the Commonwealth.

Pennsylvania imposes corporate net income tax at a rate that has been declining under a legislatively enacted schedule. For tax years beginning January 1, 1995 through December 31, 2022, the rate was 9.99 percent. Pennsylvania enacted a phased reduction schedule beginning with tax years starting on or after January 1, 2023, with the rate declining incrementally until it reaches 4.99 percent for tax years beginning on or after January 1, 2031. For tax years beginning in 2023, the rate is 8.99 percent. The rate continues to decrease by 0.5 percentage points each year through 2031.

The tax is imposed on a corporation's taxable income as determined under the Internal Revenue Code, subject to Pennsylvania-specific additions and subtractions, and is apportioned to Pennsylvania using a single-sales-factor formula for multistate corporations.

Pennsylvania imposes Corporate Net Income Tax (CNIT) on federal taxable income as determined on Form 1120, line 28 (before federal net operating loss and special deductions), with further Pennsylvania-specific additions and subtractions. Historically, this base was calculated using federal taxable income as returned to and ascertained by the federal government, then modified by specified Pennsylvania adjustments under 72 P.S. § 7401(3)1. The correct and current statutory definitions related to CNIT calculation are now best cited at the Pennsylvania legislature's site (see links below), as the previously cited URL was inactive as of July 2024.

Material statutory changes effective for tax years beginning after December 31, 2024 (Act 45 of 2025, H.B. 416):

• Research and Experimental (R&E) Expenses: Taxpayers must now add back any federal deduction for research and experimental expenditures under IRC §§ 174, 174A, 59(e) or 481, for tax years beginning after December 31, 2024. The added-back amount must be amortized over five years at 20% per year for Pennsylvania purposes (mirroring the new state rule).

• Qualified Property Depreciation (QPP/BONUS): Federal deductions for qualified property under IRC § 168(n) must be added back. Instead, Pennsylvania requires depreciation be computed under the standard IRC § 167 and § 168 rules, explicitly excluding bonus depreciation and the new § 168(n) regime.

• Interest Expense Limitation (IRC § 163(j)): For tax years beginning after December 31, 2024, Pennsylvania requires the federal business interest limitation rules under IRC § 163(j) as in effect on December 31, 2024 (i.e., Pennsylvania decouples from any federal changes after that date). Taxpayers are to reflect the limitation on the pro-forma federal return for Pennsylvania purposes; no separate adjustment line appears on RCT-101 under current administrative instructions.

All other Pennsylvania modifications remain in effect—including required add-backs for state and foreign income taxes deducted federally, restrictions on federal NOLs and dividends received, and subtractions for certain U.S. obligations and dividends gross-up. Corporations filing federal consolidated returns must continue to prepare pro-forma separate company returns for the Pennsylvania base calculation; federal consolidated return elections remain binding for state purposes.

These modifications are in effect for tax years beginning after December 31, 2024, under authority of Act 45 of 2025 (H.B. 416). Returns for tax years beginning prior to January 1, 2025 continue to follow the earlier CNIT base calculation rules.

Pennsylvania apportions multistate corporate income using a single-sales-factor formula. The apportionment percentage equals the ratio of Pennsylvania sales to total sales everywhere. Sales of tangible personal property are attributed to Pennsylvania if the property is delivered or shipped to a purchaser within Pennsylvania, regardless of f.o.b. point. Certain industries—including railroad, truck, bus, airline, pipeline, and natural gas entities—use specialized apportionment formulas prescribed elsewhere in the regulations.

Source: 61 Pa. Code § 153.26

Pennsylvania corporate net income tax returns (Form RCT-101) are due on the 15th day of the month following the due date of the federal corporate income tax return (Form 1120). For calendar-year corporations, this means the return is due May 15, as the federal Form 1120 deadline is April 15. This categorical rule reflects the change enacted by Act 10 of 2021, which shifted the previous "30 days after the federal due date" framework to the current "15th day of the following month" deadline. Fiscal-year filers apply the same rule based on their respective federal due dates.

A corporation that obtains a federal filing extension by submitting IRS Form 7004 also receives an automatic extension for Pennsylvania returns; however, the extension applies only to the time to file, not the time to pay any tax due.

Source: 61 Pa. Code § 20.8 Source: 2024 REV-1200 Corporate Net Income Tax Report instructions, "When to File"

When the Pennsylvania Department of Revenue assesses a corporate net income tax deficiency or makes an estimated assessment, the taxpayer receives written notice of the assessment. Under 61 Pa. Code § 35.2(11), the date prescribed for payment of a deficiency or estimated assessment is 30 days after notice of the assessment is mailed to the taxpayer.

The assessment notice triggers both a payment deadline and the taxpayer's administrative appeal period. While the regulation governing assessments sets the 30-day payment window, the actual protest mechanism operates through Pennsylvania's petition for reassessment process administered by the Board of Appeals.

Filing a Petition for Reassessment

A taxpayer who disputes a Department assessment must file a petition for reassessment with the Department's Board of Appeals, serving as the formal protest of the assessed deficiency. For most corporation taxes—including corporate net income tax—the statutory protest deadline is 60 days after the mailing date of the notice of assessment (see 72 P.S. § 9702(a)(1)). This supersedes the regulatory default of 90 days found in 61 Pa. Code § 7.14 for taxes without a specific statutory deadline. The 60-day period is confirmed in recent Pennsylvania Department of Revenue publications and remains current as of this update, replacing the prior 90-day convention in agency regulations.

Petition Content and Filing

Under 61 Pa. Code § 7.14(e), a petition must be in writing and contain:

• The taxpayer's name, address, and account or file number
• A clear and concise statement of the taxpayer's interest
• Facts supporting the petition and the basis for requested relief
• All required documentation and attachments

Petitions may be filed by hand delivery, mail, facsimile, or electronically through the Department’s website. A petition transmitted by mail is considered filed on the postmark date (see 72 P.S. § 1102.1).

Effect of Filing

Timely petitioning initiates administrative review before the Board of Appeals. The assessment is stayed pending review, and additional appeals may be taken to the Board of Finance and Revenue as described in the next section.

Pennsylvania corporate net income tax disputes follow a three-tier administrative and judicial review process before reaching Commonwealth Court. Each level is governed by specific statutes and procedural rules under the Tax Reform Code of 1971 and Title 61 of the Pennsylvania Code.

Step 1: Board of Appeals (Department-Level Review)

The first level of review is the Board of Appeals, an internal body within the Pennsylvania Department of Revenue. After the Department issues an assessment or denies a refund claim, the taxpayer files a petition for reassessment or petition for refund with the Board of Appeals. Under 61 Pa. Code § 7.14, petitions must generally be filed within 90 days of the date of the Department's notice of assessment or decision (or within the specific time limit prescribed by statute for the particular tax type). The Board of Appeals conducts an administrative review of the Department's determination and issues a written decision.

Step 2: Board of Finance and Revenue (Independent Appellate Review)

If the taxpayer disagrees with the Board of Appeals' decision, the next step is to petition the Board of Finance and Revenue, an independent body established under the Fiscal Code. Under 61 Pa. Code § 36.11(a), the taxpayer must file a petition for review with the Board of Finance and Revenue within 60 days after the date of mailing of the Board of Appeals' decision. (Note: Act 43 of 2017 amended the appeal period from 90 days to 60 days, effective October 30, 2017.)

If the Board of Appeals fails to issue a decision within six months of the petition filing date (or within an additional six months if stipulated by the Board and the petitioner), this failure acts as a denial of the petition. In that case, the taxpayer may file a petition for review with the Board of Finance and Revenue within 120 days of the date by which the Board of Appeals should have issued a decision, per 61 Pa. Code § 36.11(b).

The Board of Finance and Revenue conducts hearings under procedural rules codified at 61 Pa. Code Chapter 703. Hearings are typically held at the Riverfront Office Center, 1101 South Front Street, Suite 400, Harrisburg, PA 17104-2539, per 61 Pa. Code § 703.31(b). The Board issues a written order, which is a final administrative determination.

Step 3: Commonwealth Court (Judicial Review)

Appeals from final orders of the Board of Finance and Revenue are taken directly to the Commonwealth Court of Pennsylvania, the intermediate appellate court with exclusive jurisdiction over state tax appeals. Under Pennsylvania Rule of Appellate Procedure 1571(b), the appeal period is governed by specific rules for Board of Finance and Revenue determinations. A request for reconsideration to the Board does not substitute for a court appeal, but if reconsideration is granted, the time for appeal is stayed until the Board issues a reconsidered order, which then becomes the final appealable order (61 Pa. Code § 703.41(a)).

Pennsylvania imposes distinct statutes of limitations on the Department of Revenue's authority to assess additional corporate net income tax and on a taxpayer's right to claim a refund. Both are measured from the later of the return filing date or the end of the tax year, with extensions for specific circumstances.

Assessment Statute of Limitations—General Rule

Under 61 Pa. Code § 35.1(c)(1), where a corporate tax return has been filed and the deficiency arises from either underpayment or understatement of tax, the Department must assess the tax within three years after the date the return was filed or the end of the year in which the tax liability arose, whichever occurs last. This assessment may be made at any time during the three-year period, even if the Department has previously assessed the taxpayer for the same year or part of the year.

For example, if a corporation files its 2023 calendar-year return (due April 30, 2024, under Pennsylvania's 30-day-after-federal-due-date rule) on the due date, the assessment period runs three years from April 30, 2024—expiring April 30, 2027. If the corporation files late (say, on June 15, 2024), the period runs three years from June 15, 2024.

Extensions of the Assessment Period

The three-year general period may be extended in the following circumstances:

• Amended returns: If the taxpayer files an amended corporate tax report, the taxpayer must consent in writing to extend the assessment period to one year from the date of filing the amended report or three years from the filing of the original report, whichever expires last (61 Pa. Code § 151.14(b); 72 P.S. § 7407.4).

• Federal changes: If the IRS changes or corrects the taxpayer's federal taxable income, the taxpayer must report the change to the Department within 30 days of receiving the final federal determination. This report may trigger a Pennsylvania reassessment outside the normal three-year period (61 Pa. Code § 153.15(a)).

• Fraud or failure to file: The regulations do not specify an unlimited assessment period for fraud or failure to file a return for corporate net income tax in the same explicit manner as some other states. Pennsylvania practitioners should review 72 P.S. § 7407 (assessment periods under the Tax Reform Code) for any statutory extensions beyond the general three-year rule.

Refund Claim Statute of Limitations

Pennsylvania's refund claim deadline for corporate taxes is governed by the petition for refund procedure. Under 61 Pa. Code § 119.13 and § 119.18, a taxpayer seeking a credit or refund must file a petition for refund in accordance with Chapter 7 (Board of Appeals) and within applicable statutory limitation periods. The Tax Reform Code generally requires that refund petitions be filed within three years of the date of overpayment or the end of the year in which the overpayment was made, though specific statutory language in 72 P.S. § 7407 and related provisions should be consulted for the precise deadline applicable to corporate net income tax.

Settlement Timeline

While not a statute of limitations, the Department aims to settle (audit and finalize) corporate tax reports within 18 months after the report is required to be filed, per 61 Pa. Code § 153.2(a). If the taxpayer requests an extension of time to file, the 18-month settlement goal runs from the date the Pennsylvania return is actually filed. This administrative timeline does not extend or shorten the three-year statutory assessment period.

Pennsylvania offers two mechanisms for taxpayers to proactively address tax obligations or obtain guidance: the Voluntary Disclosure Program (VDA) for unreported liabilities and the private letter ruling process for prospective interpretive advice.

Voluntary Disclosure Program

The Pennsylvania Voluntary Disclosure Program allows businesses and individuals who have recently become aware of their Pennsylvania tax obligations to come forward voluntarily, file required returns, and pay tax and interest owed in exchange for penalty waiver and a limited look-back period. The program is administered by the Department of Revenue's Voluntary Disclosure Office.

Eligibility

• Available only to taxpayers not already registered with the Department of Revenue for the tax type in question.
• The taxpayer must not be under investigation or subject to collection action by the Department.
• Corporate tax liabilities of foreign and domestic corporations already registered with the Pennsylvania Department of State or Department of Revenue are not eligible for the Voluntary Disclosure Program under current Department policy.

Because most corporations doing business in Pennsylvania are required to register with the Department of State (for corporate qualification) and file RCT-101 corporate tax reports, the VDA program has limited applicability to corporate income tax. It is primarily used for sales/use tax, employer withholding, and personal income tax for pass-through entities or individuals.

Look-Back Period and Penalty Waiver

Participants in the Voluntary Disclosure Program must file returns and pay taxes and interest for up to three years plus the current year. In exchange, penalties are waived when the taxpayer completes all requirements of the Voluntary Disclosure Agreement. The taxpayer agrees not to contest any of the taxes reported under the VDA.

Anonymous Filings

Pennsylvania's published VDA guidance does not explicitly authorize anonymous or "Jane Doe" filings during the initial inquiry phase. Taxpayers or their representatives should contact the Voluntary Disclosure Office directly to confirm whether anonymous preliminary discussions are permitted.

Private Letter Rulings

The Department of Revenue, through its Office of Chief Counsel, issues private letter rulings to advise taxpayers on the Department's application of tax laws to specific factual situations. The private letter ruling mechanism is governed by 61 Pa. Code § 3.3.

Eligibility and Scope

• A private letter ruling applies to a specific taxpayer and a specific set of facts. The Department will not issue rulings on general or hypothetical questions.
• The Department will not issue "comfort" rulings on issues clearly and adequately addressed by existing statutes, regulations, court decisions, tax bulletins, or forms.
• The ruling is binding on the Department (based on the facts provided) but not binding on the taxpayer. A taxpayer may not appeal or challenge the conclusions in a letter ruling; it is not an adjudication.

Request Procedure

A written request must:

• Specifically identify the taxpayer(s) to whom the ruling will be issued.
• Contain all relevant facts and complete copies of relevant documents (contracts, agreements, tax forms, etc.).
• Pose specific legal questions to be answered.

Requests are submitted to:

Pennsylvania Department of Revenue Office of Chief Counsel P.O. Box 281061 Harrisburg, PA 17128-1061 Fax: 717-772-1459 Email: ra-rvchiefcounsel@pa.gov

Auditor General Approval

For taxes (including corporate net income tax) where the Auditor General has statutory authority to approve determinations of tax liability, letter ruling requests must be approved by the Auditor General before the Department can issue the ruling.

Duration and Revocation

A private letter ruling has a five-year term during which the taxpayer may rely on it, absent a subsequent statutory or regulatory change or Department revocation or modification. Only the taxpayer to whom the ruling is issued may rely on it; third parties may not rely on another taxpayer's letter ruling even if the facts are identical.

For tax years beginning on or after January 1, 2014, Pennsylvania sources receipts from sales of services for Corporate Net Income Tax (CNIT) apportionment using a market-based sourcing regime, as enacted by Act 52 of 2013. The prior cost-of-performance rule was specifically repealed for services, and market-based sourcing applies regardless of where the service is performed.

Hierarchy of sourcing rules

Under PA Dept. of Revenue Information Notice Corporation Taxes 2014-01:

• First, a receipt from a service is sourced to Pennsylvania if the service is delivered to a location in Pennsylvania.
• Second, if the delivery location cannot be determined, the receipt is sourced to the location where the customer receives the benefit of the service, if ascertainable.
• Third, if neither delivery nor benefit location can be established, the receipt is sourced to the location from which the customer placed the order for the service.
• Fourth, if none of the above locations can be determined, the receipt is sourced to the customer's billing address or the address indicated in the customer’s books and records.

These rules apply to both business and individual (other than sole proprietor) customers, with the stepwise method intended to capture the location where the service is received or enjoyed. Each prong must be attempted in order, and only if the preceding cannot be substantiated should the next be used, as made explicit in the Notice and related guidance.

Receipts from sales of intangibles, such as licenses or royalties, did not use market-based sourcing until tax years beginning in 2023. For services, however, market-based sourcing has applied since the January 1, 2014 effective date.

This framework closely tracks the regulatory language found in Information Notice Corporation Taxes 2014-01 and should be interpreted in light of detailed examples included in the Notice.

For tax years beginning on or after January 1, 2023, Pennsylvania requires market-based sourcing for receipts from most sales and licenses of intangible property, replacing the prior cost-of-performance approach. Act 53 of 2022 amended 72 P.S. § 7401(3)2.(a)(16.1) and § 7401(3)2.(a)(17) to provide that receipts from intangibles are sourced to Pennsylvania if the customer's benefit from the intangible is received in Pennsylvania, consistent with the treatment of sales of services, rather than where the income-producing activity is performed.

Categories of Intangible Receipts Covered

The statute, as amended, and Corporation Tax Bulletin 2024-01 clarify that market-based sourcing applies to:

• Leases and licenses of intangible property (such as patents, copyrights, trademarks, and franchises) to the extent that the property is used in Pennsylvania, or, in the case of marketing intangibles, if marketed to customers in Pennsylvania.
• Receipts from sales or exchanges of contract rights, government licenses, or similar intangibles granting the right to use property or conduct business in a specific geographic area—sourced to the location of use within Pennsylvania.
• Interest, fees, and penalties from credit card receivables and loans secured by real or tangible personal property—sourced by the location of the collateral, and if unsecured, by the billing address of the customer in Pennsylvania.
• Receipts from sales of securities or similar financial instruments held primarily for sale to customers (not investment assets)—sourced to where the customer receives the benefit.

Throw-Out Rule for Unspecified Intangible Receipts

Receipts from other intangibles not specifically addressed by the amended statute are excluded from both the numerator and denominator of the sales factor ("throw out") for apportionment purposes under 72 P.S. § 7401(3)2.(a)(17).

For detailed interpretive guidance and examples, see Pennsylvania Dept. of Revenue Corporation Tax Bulletin 2024-01.

Pennsylvania limits the amount of corporate net operating loss (NOL) that may be deducted against taxable income for Corporate Net Income Tax (CNIT) purposes, using a percentage-of-income cap and a statutory phase-in schedule.

Limitation mechanics and current law For taxable years beginning after December 31, 2018 and before January 1, 2025, the NOL deduction is limited to 40% of taxable income (as computed after apportionment but before subtracting the NOL), per 72 P.S. § 7401(3)4.(c)(1)(A). This limitation applies whether the loss is generated in the current year or carried forward from one or more prior years, and the cap is applied in the aggregate to total NOLs claimed in any year. The applicable percentage is confirmed in the Department’s CNI Audit Manual and the REV-1200 Report Instructions for current returns.

Phase-in of increased caps (2025–2029) Act 53 of 2022 amended the Tax Reform Code of 1971 to increase the NOL deduction limitation—applied in the aggregate per tax year—according to the following schedule (for taxable years beginning after December 31 of the year preceding each listed year):

• Taxable years beginning after Dec. 31, 2024 (2025 returns): 50% limitation
• Taxable years beginning after Dec. 31, 2025 (2026 returns): 60% limitation
• Taxable years beginning after Dec. 31, 2026 (2027 returns): 70% limitation
• Taxable years beginning after Dec. 31, 2027 (2028 and after): 80% limitation

The higher limitation applies to the aggregate NOL deduction for each taxable year, regardless of when the NOL was generated, according to the wording in 72 P.S. § 7401(3)4.(c)(1)(B). The statute states the percentage “for any taxable year,” and the CNI Audit Manual and instructions do not indicate that losses generated before the effective date are subject to a lower limit when claimed in later years. Any unused NOLs can be carried forward for up to 20 years.

Pennsylvania sources receipts from sales of services for Corporate Net Income Tax (CNIT) apportionment using a market-based sourcing framework for tax years beginning on or after January 1, 2014. This shift from cost-of-performance to market-based sourcing was enacted by Act 52 of 2013 and codified in the Tax Reform Code, with interpretive guidance issued in PA Dept. of Revenue Information Notice Corporation Taxes 2014-01.

Market-Based Sourcing Rule For tax years starting January 1, 2014 and after, a sale of a service is sourced to Pennsylvania for apportionment if the service is delivered to a location in Pennsylvania. If the delivery location cannot be readily determined, the service receipt is sourced first to the location where the customer receives the benefit, then, if that cannot be determined, to the place where the order was placed, and finally, if none of those can be established, to the customer’s billing address or the address shown in the records of the seller. All prongs must be applied in hierarchical order—prong 2 is available only when prong 1 cannot be factually substantiated, and so forth.

Legal Hierarchy

• Prong 1: Receipt is sourced to PA if service is delivered to a PA location.
• Prong 2: If delivery cannot be determined, source to where customer receives the benefit.
• Prong 3: If location of benefit cannot be established, use the location from which customer placed the order.
• Prong 4: If none above are determinable, use the customer’s billing address or address on record.

This rule applies to all corporate taxpayers except those specifically excluded by statute (e.g., certain transportation or pipeline companies with industry-specific sourcing provisions). For apportionment, these receipts form the Pennsylvania numerator in the single-sales-factor formula.

Effective Date Market-based sourcing for service receipts applies to all tax years beginning on or after January 1, 2014; prior years used the cost-of-performance test, which has been repealed for sales of services.

Pennsylvania sources receipts from the sale, lease, license, or other disposition of intangible property for corporate net income tax apportionment using a market-based approach, effective for tax years beginning after December 31, 2022, pursuant to Act 53 of 2022.

Statutory rule and scope Under 72 P.S. § 7401(3)2.(a)(17), as amended by Act 53 of 2022, gross receipts from intangible property are included in the numerator of the Pennsylvania sales factor as follows:

• Receipts from leasing or licensing intangible property (including receipts from sales where payment depends on the property's use, productivity, or disposition) are sourced to Pennsylvania to the extent the property is used in the Commonwealth.
• Receipts from the sale of contract rights, government licenses, or similar property authorizing business activity in a specific geographic area are sourced to Pennsylvania to the extent the property is used in or otherwise associated with the state.
• Interest, fees, and penalties from credit card receivables and loans backed by real or tangible property are sourced by the location of the collateral. For unsecured loans and credit card receivables, the source is the customer’s billing address as per the creditor's records.
• Receipts from sales of securities or financial instruments held primarily for sale to customers are sourced to the location where the customer receives the benefit.

Receipts from intangible items not specifically addressed in the statute are "thrown out" (excluded) from both the numerator and denominator under § 7401(3)2.(a)(17).

Effective date Act 53 of 2022 amended the statute to adopt market-based sourcing for these receipts for tax years starting after December 31, 2022. Before this, intangible receipts were sourced under a cost-of-performance standard (receipts attributed to Pennsylvania if the greater proportion of the income-producing activity occurred within the state).

Department of Revenue guidance Corporation Tax Bulletin 2024-01, issued January 5, 2024, gives examples and interpretive details. For instance, royalties for trademarks used in manufacturing/ad sales in Pennsylvania are sourced to the state, and credit card interest is sourced by the billing address for unsecured cards. The bulletin also clarifies "throw-out" rules for unspecified intangibles.

Pennsylvania applies a rebuttable presumption of corporate net income tax (CNIT) nexus to corporations (including remote corporations with no physical presence) that have $500,000 or more of gross receipts sourced to Pennsylvania in a single taxable year. The Department of Revenue first announced this threshold in Corporation Tax Bulletin 2019-04, which stated that for tax years beginning on or after January 1, 2020, corporations exceeding the $500,000 Pennsylvania-sourced gross receipts threshold under the sales factor rules (72 P.S. § 7401(3)2(a)(16.1)–(17)) are presumed to have substantial nexus for CNIT purposes, even if they lack physical presence. This presumption is rebuttable; a taxpayer may provide evidence to the Department that no nexus exists despite meeting the threshold (such as exclusive protection under P.L. 86-272).

2020–2022: Bulletin-only enforcement For tax years 2020, 2021, and 2022, this economic nexus threshold was enforced solely by administrative pronouncement—i.e., Corporation Tax Bulletin 2019-04. Although not codified by statute until later, such bulletins represent the official Department position and have been enforced in audit and assessment settings. While not carrying the force of law, bulletins are given substantial deference by courts unless contrary to statute, and no Pennsylvania court or legislative authority declared Bulletin 2019-04 invalid for this interim period. Taxpayers exceeding the threshold during 2020–2022 who did not file CNIT returns faced real risk of assessment, and the Department has asserted such nexus in audit examinations for those years.

Statutory codification as of 2023 Act 53 of 2022 codified the $500,000 economic nexus threshold for CNIT, providing explicit legislative authority for tax years beginning after December 31, 2022 (tax year 2023 and later). The Department’s administrative framework continues, but is now backed by statute. Codification eliminated any ambiguity surrounding the enforceability of the threshold for subsequent years.

Summary and authority

• For 2020–2022, enforcement was grounded in Corporation Tax Bulletin 2019-04, and the risk of assessment remains for those years absent contrary legal authority.
• For 2023 and later, the threshold is a matter of statutory law under Act 53 of 2022.

Recognition of Public Law 86-272 Pennsylvania recognizes the federal protection granted by Public Law 86-272 (15 U.S.C. §§ 381–384) for out-of-state corporations whose only Pennsylvania activity is the solicitation of orders for the sale of tangible personal property, with orders approved and filled from outside the state. This federal law prohibits states from imposing a net income tax—such as Pennsylvania's Corporate Net Income Tax (CNIT)—on such sellers simply because they solicit sales in the state, provided no activities exceed solicitation as defined by the law. The Department of Revenue acknowledges this limitation in formal publications and bulletins. "Solicitation" means activities entirely related to requesting orders for the sale of tangible personal property to be sent outside the state for approval and fulfillment.

RCT-101 Filing Requirement for Protected Corporations Corporate taxpayers claiming P.L. 86-272 protection are still required to file the annual RCT-101 Corporate Net Income Tax Report. According to the Pennsylvania Department of Revenue's CNIT instructions and the 2024 REV-1200 instruction booklet, corporations that believe they are protected under P.L. 86-272 must check the box for "P.L. 86-272 protection" and submit the return, typically including minimal information to demonstrate the basis for the claim. Failure to file does not exempt the corporation from the obligation to establish that its activities meet the scope of the federal protection, and the Department may require additional documentation to confirm that the corporation's activities are strictly limited to solicitation as defined by law.

Department Guidance and Loss of Protection The CNIT Audit Manual lists activities that are protected under P.L. 86-272 and those that would forfeit the exemption. Examples of disqualifying activity include performing post-sale services (such as repairs), accepting returns at an in-state location, or maintaining an office, warehouse, or inventory in Pennsylvania. Corporations must keep adequate records supporting their claim and file RCT-101 annually, reporting Pennsylvania receipts and indicating the P.L. 86-272 exemption.

Direct answer Pennsylvania imposes an economic-nexus threshold for Corporate Net Income Tax when an out-of-state corporation has $500,000 or more of Pennsylvania-sourced gross receipts in a taxable year, creating a rebuttable presumption of CNIT filing obligation, effective for filing periods beginning January 1, 2020.

Why The Department of Revenue’s Corporation Tax Bulletin 2019-04, issued in response to the Wayfair decision, established this bright-line threshold. It applies to gross receipts from:

• sale, rental, lease, or licensing of tangible personal property;
• sale of services; and/or
• sale or licensing of intangibles (including franchise agreements).

The threshold operates as a rebuttable presumption—taxpayers can argue nexus does not exist despite exceeding it. The Department acknowledges protection under Public Law 86-272: even if the $500,000 threshold is exceeded, taxpayers limited to mere solicitation of tangible personal property and otherwise qualifying under P.L. 86-272 may claim that exemption.

The threshold applied to tax periods beginning January 1, 2020, as stated in the RCT-101 instructions and Bulletin 2019-04.

Caution / review status Not yet human confirmed. This section relies on Bulletin 2019-04 and the CNIT Audit Manual; the classification of receipts and P.L. 86-272 interplay should be reviewed by a SALT expert.

Pennsylvania uses market-based sourcing to apportion receipts from sales of both services and intangibles for Corporate Net Income Tax (CNIT) purposes, but the effective dates and specific rules differ for each category.

Services (market-based sourcing, effective 2014) For tax years beginning on or after January 1, 2014, Pennsylvania sources service receipts to the state where the benefit of the service is received (i.e., market-based sourcing). This regime replaced the prior cost-of-performance rule. The statutory change, enacted by Act 52 of 2013 and codified at 72 P.S. § 7401(3)2.(a)(16.1), is further interpreted in PA Dept. of Revenue Information Notice Corporation Taxes 2014-01. The DOR instructs:

• Source to Pennsylvania if the service is delivered to a location in Pennsylvania.
• If the delivery location cannot be determined, source to where the customer receives the benefit.
• If neither can be determined, use the place where the customer ordered the service.
• If none of these are determinable, source to the billing address or the address in customer records.

All steps must be attempted in order, not by taxpayer preference.

Intangibles (market-based sourcing, effective 2023) For tax years beginning on or after January 1, 2023, Act 53 of 2022 amended 72 P.S. § 7401(3)2.(a)(17) to require market-based sourcing for receipts from intangibles (e.g., royalties, licenses, credit card interest) where the benefit or use of the intangible occurs in Pennsylvania. DOR Corporation Tax Bulletin 2024-01 and the statute provide examples:

• For patents, trademarks, and other licenses, source to Pennsylvania to the extent the property is used or marketed here.
• For credit card and unsecured loan interest, source to the customer’s billing address.
• Receipts not specifically described in statute are “thrown out”—excluded from numerator and denominator.

Practical impact For both categories: if a taxpayer cannot specifically identify the benefit or market location, fallback criteria (ordering location, billing address) apply in ordered sequence. Only receipts that can be sourced to Pennsylvania through this process are included in the numerator of the single-sales-factor apportionment formula.

Pennsylvania's Corporate Net Income Tax (CNIT) base begins with federal taxable income as determined on federal Form 1120, Line 28, before the federal net operating loss deduction and special deductions. However, Pennsylvania law requires a series of statutory additions and subtractions to this federal starting point before apportionment and any net operating loss (NOL) deduction.

Key Pennsylvania Additions

• Taxes based on or measured by net income: Any taxes imposed by the United States, Pennsylvania, other states, or foreign countries, measured by net income and deducted on the federal return, must be added back. This specifically includes the federal corporate income tax, the Pennsylvania CNIT itself (if deducted federally), and other state or foreign income/franchise taxes. (72 P.S. § 7401(3)1.(a); CNIT Audit Manual ch. V)
• Bonus depreciation (IRC § 168(k) and § 168(n)): For property placed in service after December 31, 2024, corporations must add back any federal deduction for bonus depreciation taken under IRC § 168(k) or § 168(n). (Act 45 of 2025 Bulletin at "CNIT – Bonus Depreciation")
• Research and experimental (R&E) amortization: Effective for tax years beginning after December 31, 2024, Pennsylvania decouples from the IRC § 174 federal requirement to amortize R&E expenditures over five years. Any federal R&E amortization deduction claimed for expenses incurred after this date must be added back. (Act 45 of 2025 Bulletin)
• Federal business interest limitation (IRC § 163(j)): For tax years beginning after December 31, 2024, Pennsylvania does not conform to the federal interest deduction limitation under IRC § 163(j); interest disallowed under federal law is added back if deducted federally. (Act 45 of 2025 Bulletin)

Key Pennsylvania Subtractions

• Dividend gross-ups on foreign subsidiaries: Amounts included as dividend gross-up (IRC § 78) in federal income are subtracted for CNIT purposes. (CNIT Audit Manual ch. VI; 72 P.S. § 7401(3)1.(a)(v))
• Interest income and gains from U.S. obligations: Net interest income and gains from U.S. government securities (such as Treasury notes and bonds), to the extent included in federal income, are subtracted. (CNIT Audit Manual ch. VI)

Other Notable Adjustments

• NOL deduction limitation: Pennsylvania imposes percentage caps and a multi-year phase-in for the amount of NOL that may be deducted. See the section Net operating loss deduction limitation and phase-in schedule (2024–2029).
• Separate company returns: Corporations filing a federal consolidated return must determine Pennsylvania taxable income on a separate-company basis (pro-forma federal calculation). (Tax Compendium 2025 at p. CNIT-6)

Authority and Updates These rules arise from the Tax Reform Code of 1971 § 401(3), annual DOR bulletins, the CNIT Audit Manual, and recurring updates and conformity changes documented in the DOR's tax compendium and bulletins. Act 45 of 2025 establishes the effective dates for recent decoupling from federal rules on bonus depreciation, R&E amortization, and business interest limitations.

Direct answer: Pennsylvania requires corporations to compute Corporate Net Income Tax (CNIT) on a separate-company basis. Combined or unitary reporting is not required for most affiliated groups, and consolidated/combined returns are not permitted except in limited anti-avoidance circumstances.

Why: Under Pennsylvania law, each corporation must file and pay CNIT on its own taxable income, regardless of affiliation with other entities. The general rule (72 P.S. § 7402) and implementing regulations (61 Pa. Code § 153.11) require a separate-company filing, even if the corporations file a federal consolidated return. Pennsylvania does not allow affiliated groups to elect combined or consolidated reporting for general CNIT purposes, in contrast to certain other states. Instead, corporations filing on a consolidated basis for federal purposes must prepare a pro forma federal return as if they had filed on a separate-company basis for Pennsylvania purposes.

Prohibition of forced or combined reporting: Pennsylvania statute expressly prohibits both elected and forced combination (unitary or consolidated) for CNIT purposes, regardless of corporate structure. 72 P.S. § 7404 states that: "The department shall not permit any corporation owning or controlling, directly or indirectly, other corporations, or being owned or controlled, directly or indirectly, by other corporations, to make a consolidated report showing the combined net income of such corporations." This is an explicit legal bar. The Department of Revenue has no statutory or regulatory authority to impose a forced combined return, even as an anti-avoidance or abuse-prevention measure. There are no formal or informal published standards, administrative procedures, or Departmental bulletins permitting forced combined reporting, and no court decisions have created an exception to the statutory prohibition. All related corporations must file and be assessed separately, and any adjustments for intercompany transactions or potential abuse must be handled on a separate-company basis (e.g., add-back statutes), not by requiring a combined report.

Confirmation in Department and Commission Reports: Both Department of Revenue publications and Pennsylvania Tax Reform Commission reports confirm that combined/unitary CNIT reporting is legally prohibited. The Department’s Audit Manual, Tax Compendium, and administrative guidance contain no examples of or instructions for forced combination because the authority does not exist in Pennsylvania law or practice. If the General Assembly were to authorize mandatory or elective combined reporting, it would require legislative action.

Summary: Except for rare forced-combination cases, Pennsylvania CNIT requires separate-company returns from each corporation with Pennsylvania nexus. In practice, even forced-combination or anti-avoidance combination is not permitted; all reporting and audit adjustments are handled on a separate-company, non-combined basis, as required by statute.
