Rhode Island — Corporate Income / Franchise Tax

Rhode Island imposes a corporate income tax under Chapter 44-11, known as the Business Corporation Tax. As of the current tax year, each corporation doing business in Rhode Island must pay an annual tax equal to 7% of net income apportioned to Rhode Island. This rate is unchanged for tax years through June 30, 2026.

Minimum Tax — Material Change Effective July 1, 2026: For tax years beginning on or after January 1, 2017, and prior to July 1, 2026, every corporation (including S corporations) was subject to a statutory minimum annual tax of $400, regardless of income or Rhode Island receipts. However, effective for tax years beginning after July 1, 2026, the Rhode Island General Assembly repealed the minimum corporate tax. Beginning with tax years starting after this date, there will be no minimum business corporation tax for C corporations or S corporations. Rhode Island thus joins a small set of states that do not require a minimum tax payment for inactive or low-income corporations. Practitioners should review entity formation and return-filing practices in light of this change, as the $400 tax will not apply to returns filed for periods beginning after July 1, 2026.

This change is contained in the 2026 amendments to R.I. Gen. Laws § 44-11-2(e), as enacted by Rhode Island Public Law 2026, ch. 120, and confirmed in the Division of Taxation news release. The standard tax rate of 7% continues to apply on taxable net income apportioned to Rhode Island after that date.

Net income is based on federal taxable income, modified by Rhode Island-specific additions and subtractions as defined in R.I. Gen. Laws § 44-11-11. S corporations are not generally subject to the 7% entity-level tax, but were previously subject to the minimum tax, which is now eliminated for tax years beginning after July 1, 2026. The tax applies to C corporations doing business in Rhode Island unless exempted by P.L. 86-272.

For tax years beginning on or after January 1, 2015, C corporations conducting business both within and outside Rhode Island must apportion net income using a single sales factor. The apportionment percentage is calculated by dividing Rhode Island receipts by total receipts everywhere. For sales of services and intangible property, receipts are sourced using market-based sourcing, which attributes the sale to Rhode Island where the customer receives the benefit of the service or uses the intangible. This single-factor method replaced the prior three-factor formula (property, payroll, and sales) for C corporations.

Rhode Island imposes corporate income tax on foreign corporations with Rhode Island business activity unless protected by Public Law 86-272. Any amount of physical presence, however limited, presumptively triggers income tax nexus; physical presence is established through holding property, activities of agents or representatives, maintaining an office, or similar connections. In the absence of physical presence, substantial nexus can be established through economic presence if the corporation has created continuing obligations and relationships with state residents such that it has purposefully availed itself of state markets, benefits, or protections. Rhode Island uses a facts-and-circumstances approach rather than specific factor-presence thresholds (such as dollar amounts for revenue, property, or payroll).

Rhode Island corporate income tax returns on Form RI-1120C are due according to the following schedule:

• For calendar-year and all non–June 30 fiscal-year filers, the return is due on or before the fifteenth day of the fourth month following the close of the taxable year (typically April 15 for calendar-year taxpayers).
• For filers whose fiscal year ends on June 30, the return is due on or before the fifteenth day of the third month following the close of the taxable year (i.e., September 15).

This June 30 exception is explicitly stated in Rhode Island Division of Taxation guidance and in the official instructions for Form RI-1120C.

The tax payment is also due on the same date as the corresponding filing deadline. Returns are considered timely if mailed with a U.S. postmark dated on or before the due date.

Rhode Island corporations must make quarterly estimated tax payments if their estimated tax liability for the year can reasonably be expected to exceed $500. This threshold applies to C corporations, S corporations (for the $400 minimum tax), and other entities subject to the business corporation tax under Chapter 44-11. The requirement applies regardless of whether federal estimated payments are required.

Payment schedule and amounts

For calendar-year corporations, four equal installments of 25% each are due on April 15, June 15, September 15, and December 15 of the taxable year. For fiscal-year filers, the installments are due on the 15th day of the fourth, sixth, ninth, and twelfth months of the taxable year. Corporations report estimated payments on Form BUS-EST. The payments are credited against the final tax liability when the annual return (Form RI-1120C for C corporations) is filed.

Safe harbor rules to avoid underpayment interest

Rhode Island provides two safe harbor methods to avoid underpayment interest. A corporation satisfies the safe harbor if its quarterly installments equal either (1) 100% of the current year's tax liability, or (2) 100% of the prior year's tax liability calculated at the current year's tax rate. For taxpayers required to file a combined report under R.I. Gen. Laws § 44-11-4.1 beginning on or after January 1, 2015, the safe harbor is satisfied if installments equal 100% of the prior year's tax plus any additional tax due to the combined reporting provisions, or 100% of the current year's tax liability. The regulation previously allowed a safe harbor based on 100% of the prior year's tax without rate adjustment, but R.I. Gen. Laws § 44-26-2.1 eliminated that exception; the current safe harbor based on prior-year income at the current-year rate remains.

Interest on underpayments

If a corporation underpays its estimated tax, Rhode Island assesses interest at the rate of 18% per annum on the amount of the underpayment for the period of underpayment. Interest is calculated and reported on Form RI-2220 when filing the annual return. Willful failure to file a declaration or pay an installment may also trigger penalties under R.I. Gen. Laws § 44-26-9.

Amended declarations

A corporation may file an amended estimated tax declaration if its estimated liability increases or decreases during the year. If an amended declaration is filed, any remaining installments are ratably adjusted to reflect the change. If the amendment is made after the due date of an installment, the corporation must pay any resulting increase at the time of filing the amendment, though underpayment interest may still apply.

Rhode Island allows corporations to request a six-month extension of time to file corporate income tax returns by filing Form RI-7004 (Automatic Six Month Extension Request for RI-1120C, RI-1120S and RI-1065 Filers) on or before the original due date of the return. The extension applies to C corporations, S corporations, and partnerships. Under Rhode Island regulations, no extension for filing shall exceed six months, except for taxpayers outside of the United States.

Extended deadlines for calendar-year filers

For calendar-year C corporations, the original due date is April 15 (the 15th day of the fourth month following the close of the taxable year). A six-month extension moves the filing deadline to October 15. For calendar-year S corporations and partnerships, the original due date is March 15 (the 15th day of the third month following the close of the taxable year), and a six-month extension moves the filing deadline to September 15.

Payment requirement — no extension of time to pay

The filing extension does not extend the time to pay the tax. A corporation must pay the full amount of its estimated tax liability by the original due date to avoid interest and penalties. Payment may be remitted with Form RI-7004 or made electronically through the Rhode Island Taxpayer Portal at tax.ri.gov. Rhode Island assesses interest at 18% per annum on late payments under R.I. Gen. Laws § 44-11-7, and penalties may apply under R.I. Gen. Laws § 44-11-27 for failure to file or pay.

Rhode Island form required — federal extension does not suffice

Filing federal Form 7004 does not automatically extend the Rhode Island filing deadline. A taxpayer must file Rhode Island Form RI-7004 with the Rhode Island Division of Taxation to obtain the state extension, even if a federal extension has been granted. The extension is granted without prior approval from the Division of Taxation provided the form is filed on or before the original due date and the payment requirement is satisfied.

Fiscal-year filers

For fiscal-year corporations, the six-month extension runs from the original due date. A fiscal-year C corporation whose taxable year ends on a date other than December 31 must file its return by the 15th day of the fourth month following the close of the taxable year, and the six-month extension moves the deadline six months forward from that original due date. Form RI-7004 must be filed by the original due date for the extension to be valid.

Statutory and regulatory framework

R.I. Gen. Laws § 44-11-5 authorizes the tax administrator to grant extensions of time for filing corporate income tax returns. Rhode Island regulation 280 R.I. Code R. 280-RICR-20-55-2.6 provides that no extension for filing shall exceed six months, except for taxpayers outside of the United States, pursuant to R.I. Gen. Laws § 44-30-57. The Division of Taxation administers the extension procedure through Form RI-7004.

Rhode Island requires combined reporting for unitary business groups for tax years beginning on or after January 1, 2015, under R.I. Gen. Laws § 44-11-4.1. All corporations that are members of a unitary group and have business activity in Rhode Island must file a single, combined report that includes the income and apportionment factors of all members of the unitary group, both in-state and out-of-state, to the extent permitted by federal law.

Definition and ownership threshold: A unitary group is defined as a group of corporations with more than 50% voting control, directly or indirectly, under the unitary business principle. See R.I. Gen. Laws § 44-11-4.1(a)(5) for the statutory definition.

Water’s-edge vs. worldwide election: By default, Rhode Island requires water's-edge combined reporting, meaning only income and factors of U.S.-connected entities (and certain foreign affiliates with substantial U.S.-source income) are included. Taxpayers may elect to file on a worldwide-combined basis, but this election must be made on a timely filed original return and is binding for ten years unless changed with consent of the tax administrator (R.I. Gen. Laws § 44-11-4.1(d)).

Minimum tax application: Each member of the combined group with Rhode Island nexus owes the $400 minimum tax individually; the minimum tax is not imposed per group but per entity. This is confirmed in R.I. Gen. Laws §§ 44-11-2(2) and 44-11-4.1(l).

Summary of requirements:

• Effective for tax years beginning on or after January 1, 2015
• Applies to unitary groups with >50% common ownership
• Default is water’s-edge, but a worldwide election is available and binding for 10 years
• $400 minimum tax applies to each nexus member in the group

As of 2026, Rhode Island does not impose a bright-line economic nexus threshold for purposes of its corporate income tax. The state has not adopted the type of factor-presence nexus standard seen in some other states (such as a fixed dollar amount of sales, property, or payroll in the state). Instead, Rhode Island applies a facts-and-circumstances approach to determining whether a corporation has "substantial nexus" under its Business Corporation Tax law.

Statutory and Regulatory Framework Under R.I. Gen. Laws § 44-11-1 and the implementing regulation 280-RICR-20-25-8, a foreign or domestic corporation is subject to Rhode Island corporate income tax if it is "doing business" in the state, unless protected by federal law (P.L. 86-272). The regulation describes nexus as arising from either physical presence (such as tangible property, employees, or an office) or economic presence, which can include engaging in transactions or relationships that create continuing obligations or benefits in the state. However, the regulation does NOT set a specific gross-receipts, transaction, or property/payroll dollar threshold, and affirmatively states that Rhode Island has not adopted the Multistate Tax Commission (MTC) model factor-presence nexus thresholds (e.g., $500,000 sales, $50,000 property, or $50,000 payroll).

Division of Taxation Guidance The Rhode Island Division of Taxation confirms in its official guidance that nexus for corporate income/franchise tax is assessed on a case-by-case basis. Taxpayers must examine both physical and economic contacts with the state to determine if the activity rises to the level of "doing business." No quantitative safe-harbor or dollar threshold is provided. Out-of-state corporations making sales into Rhode Island, providing services to Rhode Island customers, or licensing intangibles for use in Rhode Island may have nexus if their contacts establish a more than transitory presence, but there is no formal transaction, receipts, or property/payroll floor.

Summary Rhode Island uses a facts-and-circumstances nexus standard for corporate income tax. There is no statutory or regulatory economic threshold based on gross receipts, number of transactions, or in-state property/payroll. The presence of substantial connections—rather than crossing a bright-line factor threshold—controls the nexus determination.

Rhode Island corporate income tax begins with federal taxable income and requires statutory and regulatory modifications (additions and subtractions) to determine "Rhode Island net income" (R.I. Gen. Laws § 44-11-11).

Additions (Add-Backs) — Updated for 2026:

1. Interest from non-federally-exempt state and municipal bonds (§ 44-11-11(a)(1)(i)).
2. State/local income taxes deducted on the federal return (§ 44-11-11(a)(1)(ii)).
3. Add-back for federal deductions disallowed or decoupled by Rhode Island, including (prior to 2025) bonus depreciation and expanded business interest expense deductions (see prior emergency reg. 280-RICR-20-25-16; expires for tax years beginning after Jan. 1, 2025).
4. Cannabis-related expenditures disallowed federally under IRC § 280E—effective for tax years beginning on or after Jan. 1, 2025 (§ 44-11-11(a)(1)(vii)).
5. NEW FOR APRIL 2026: Add-back under § 44-11-11(a)(1)(viii) and new regulation 280-RICR-20-25-17: For tax years beginning on or after Jan. 1, 2026, taxpayers must add back any federal income, deduction, or allowance: (a) that would have been included in federal taxable income for tax years beginning on or before Jan. 1, 2025, but (b) for which the federal treatment was subsequently changed by federal law known as One Big Beautiful Bill (P.L. 119-21, H.R. 1). This provision is designed to decouple Rhode Island net income from specific new federal exclusions or deductions unless Rhode Island affirmatively adopts conformity. The regulation effective April 16, 2026, implements the statute and details covered items.

Subtractions:

1. Interest from U.S. obligations exempt from state tax (§ 44-11-11(a)(2)(i)).
2. Refunds of state/local taxes if previously added back (§ 44-11-11(a)(2)(ii)).
3. Other items exempt under federal or Rhode Island law (§ 44-11-11(a)(2)(v)).

Regulatory Note: The prior emergency regulation 280-RICR-20-25-16 was not renewed after returns for 2024. As of April 2026, only regulation 280-RICR-20-25-17 (add-back for federal One Big Beautiful Bill changes) is newly in effect, alongside continued statutory add-backs and subtractions.

Summary of Recent Change:

• Effective April 16, 2026, and for returns for tax years beginning on or after Jan. 1, 2026, Rhode Island requires a new add-back for certain federal tax benefits created by major federal law changes unless the state affirmatively conforms. Prior emergency decoupling on TCJA deductions expired after 2024 returns.

Rhode Island S corporations with nonresident shareholders are required to withhold Rhode Island income tax on each nonresident shareholder’s pro rata share of Rhode Island-source income unless (1) the pro rata share is under $1,000, (2) the nonresident participates in a composite return, or (3) the entity makes the PTE-level tax election under R.I. Gen. Laws § 44-11-2.3. The withholding rate is the highest marginal Rhode Island personal income tax rate for individuals (5.99% as of the 2024 tax year), as specified in R.I. Gen. Laws § 44-11-2.2.

Withholding mechanics:

• S corporations must withhold at the highest marginal individual income tax rate on each nonresident’s distributive share unless an exception applies.
• There is an exception if the Rhode Island-source income allocated to the nonresident is less than $1,000.
• Alternatively, the S corporation may file a composite return (Form RI-1040C) for nonresident individual shareholders who sign an agreement (typically Schedule SN); for shareholders who do not participate in the composite, withholding must be made.
• Effective for tax years beginning on or after January 1, 2019, an S corporation can elect to pay Rhode Island tax at the entity level, in which case the withholding obligation is relieved on resident and nonresident members alike (R.I. Gen. Laws § 44-11-2.3).

How fulfilled:

• S corporation withholds and remits tax or files a composite return using current RI Division of Taxation forms (RI-1040C for composite; RI-1120S for reporting S corp activity; Schedule SN for shareholder agreements).
• For shareholders not joining the composite, withholding is made and reported as specified by the Division of Taxation.

As of June 2026, Rhode Island has not adopted any explicit, bright-line economic nexus thresholds (such as a fixed dollar amount of sales, property, or payroll in the state) for purposes of its corporate income tax. Instead, the state continues to use a facts-and-circumstances approach to determining whether an out-of-state or foreign corporation has established sufficient nexus to be subject to the Rhode Island Business Corporation Tax, as codified at R.I. Gen. Laws § 44-11 and as confirmed in regulations and official agency publications.

No factor-presence or dollar-based standards Rhode Island has not enacted the Multistate Tax Commission (MTC) model factor-presence nexus thresholds, which would define nexus based on specific quantitative levels—such as $500,000 in sales, $50,000 in property, or $50,000 in payroll within the state. The Division of Taxation confirms in its guidance that nexus is established if a corporation's activities—whether physical or economic—rise to the level of "doing business" in Rhode Island. Both physical activities (such as property ownership or having employees) and substantial economic presence (such as transactions or sustained business relationships with Rhode Island customers) may create nexus, but no statutory or regulatory threshold is specified.

Impact of South Dakota v. Wayfair, Inc. Unlike its sales and use tax regime, which responded to the U.S. Supreme Court's decision in South Dakota v. Wayfair, Inc. by adopting specific economic nexus thresholds for remote sellers, Rhode Island's corporate income tax law and regulations have not been amended to establish a parallel, bright-line dollar threshold post-Wayfair. Nexus determinations for corporate income tax remain governed by the existing facts-and-circumstances standard.

Current law and primary authority As of this date, Rhode Island's corporate income tax regulations (280-RICR-20-25-8) specify that foreign and domestic corporations are subject to income tax if they are "doing business" in the state, unless their activities are protected by federal law such as Public Law 86-272. The regulation describes nexus as arising from either physical or economic presence but does not specify any sales, transaction, property, or payroll threshold for corporate taxpayers.

Summary Rhode Island continues to apply a facts-and-circumstances standard for corporate income tax nexus and has not imposed a bright-line economic threshold for out-of-state corporate taxpayers as of June 2026.

Rhode Island provides special apportionment rules for certain industries, most notably for financial institutions and a specific subset of manufacturers, with individual carve-outs detailed in statute and regulation.

Financial institutions and credit card banks

• Credit card banks: Under R.I. Gen. Laws § 44-11-14.3, a "credit card bank" (as defined by federal law and holding a RI business corporation tax certificate of authority) may irrevocably elect to apportion net income to Rhode Island based on the domiciles of its cardholders. The election is binding for five years and must be made according to Division of Taxation procedures. See § 44-11-14.3(a)-(c) for definition, election requirements, and effect.

• Other banking corporations: Effective January 1, 2025, R.I. Gen. Laws §§ 44-14-14.1 through 44-14-14.5 require "banking institutions" (as defined at § 44-14-2) to apportion net income using an average of property, payroll, and sales factors, replacing the standard single sales factor. The law includes relief provisions for taxpayers who can demonstrate that this formula does not fairly represent Rhode Island business activity (see § 44-14-14.5(a)). The change is prospective beginning with 2025 tax years.

Manufacturers with FDA-certified facilities

• Regulation 280-RICR-20-25-9(7)(b) allows manufacturers whose in-state assets consist of FDA-certified manufacturing and distribution facilities to exclude those designated properties from both the numerator and denominator of the property factor, provided the property is not otherwise included in the apportionment fraction under Rhode Island law. The regulation defines eligibility and requirements for this exclusion in detail.

Public utilities and other industries

• As of June 17, 2026, there is no special apportionment formula for public utilities documented in Rhode Island statute (Ch. 44-11 or 44-14) or current Department of Taxation regulations (280-RICR-20-25-9), and the available regulations do not address public utilities separately for apportionment purposes. This statement is based on the absence of an explicit formula in those authorities as of this date.

Summary

• Credit card banks: customer domicile apportionment (five-year election).
• Banking institutions: three-factor formula effective in 2025.
• FDA-certified facility manufacturers: factor exclusion for qualified properties.
• Public utilities: no confirmed deviation from the standard formula per the cited authorities.

If a Rhode Island corporate income tax filing or payment deadline falls on a Saturday, Sunday, or legal holiday recognized by the State of Rhode Island, the due date is automatically extended to the next business day. This extension applies both to the filing of returns and to required tax payments for the state corporate income tax (including estimated payments and other documents required to be submitted to the Division of Taxation).

Statutory Basis and Scope Rhode Island General Laws § 44-1-28 provides that whenever the last day for the performance of any act—including the filing of tax returns, payments, or other documents—falls on a Saturday, Sunday, or a legal holiday recognized by the state, such act is considered timely if performed on the next business day. This provision applies to all taxes administered by the Rhode Island Division of Taxation—including the business corporation tax imposed under R.I. Gen. Laws § 44-11 and the corresponding regulations.

Regulatory Confirmation This statutory rule is reiterated in Rhode Island's regulations at 280-RICR-20-00-7, which specify that a due date falling on a weekend or legal holiday is carried forward to the next business day. Payments delivered either in person or by U.S. mail are subject to this extension. If the return or payment is postmarked on or before the next business day after a weekend or holiday, it is considered filed or paid on time.

Practical Effect The practical result is that a due date extension occurs automatically—no additional action or request for extension is required by the taxpayer. This rule aligns Rhode Island with common filing convention among state tax authorities.
