Kentucky — Corporate Income / Franchise Tax

Kentucky imposes a corporate income tax on non-exempt corporations doing business in the state. The tax applies to corporations, limited liability companies, S-corporations, limited partnerships, and other business entities that have limited liability protection under state law. Sole proprietorships and general partnerships are not subject to the corporate income tax because they lack limited liability. The term "doing business" is interpreted broadly to include any profit-seeking enterprise or activity in Kentucky, regardless of whether the activities result in a profit or loss.

Kentucky uses a static conformity approach for its corporate income tax base. For taxable years beginning on or after January 1, 2026, Kentucky conforms to the Internal Revenue Code (IRC) as in effect on December 31, 2025. This conformity date was established by House Bill 757 (Acts Chapter 161, 2026 Regular Session), enacted in April 2026. Kentucky does not automatically conform to subsequent amendments or provisions enacted by Congress after December 31, 2025, unless specifically provided by statute.

Importantly, this 2026 legislation also provides that Kentucky does NOT conform to certain federal changes made by the One Big Beautiful Bill Act (OBBBA), including the R&E expenditure rules under IRC § 174A and the expanded interest limitation provisions under IRC § 163(j). For these provisions, Kentucky retains the tax treatment that applied under the Tax Cuts and Jobs Act (TCJA) regime, as in effect before the OBBBA.

For prior years, the state conformed to earlier static dates (e.g., December 31, 2024, for tax years beginning on or after January 1, 2025). The fixed IRC tie-in date should always be confirmed for the filing year, especially when there are major federal or state enactments affecting conformity.

Kentucky apportions multi-state corporate income using a single-sales-factor formula for tax years beginning on or after January 1, 2018. Apportionable income is multiplied by a fraction, the numerator of which is the taxpayer's Kentucky receipts, and the denominator of which is the taxpayer's total receipts everywhere. This formula applies to most corporations. Providers of communication and cable services (as defined in KRS 136.602), financial organizations, and public service companies use different apportionment formulas specified in KRS 141.121.

Kentucky imposes corporate income tax on non-exempt corporations "doing business" in the state. There is no minimum revenue or transaction threshold for nexus. The regulation defines "doing business" comprehensively as "any profit-seeking enterprise or activity in Kentucky," regardless of whether the activities result in a profit or loss. Examples of nexus-creating activities include performing services in Kentucky, owning or leasing property in the state, owning mineral rights, being a member of a pass-through entity doing business in Kentucky, and receiving income from intangible property with Kentucky business situs. Physical presence is not required.

Kentucky uses market-based sourcing to determine which receipts are included in the numerator of the single-sales-factor apportionment formula. The general rule is that receipts are sourced to Kentucky if the taxpayer's market for the sale is in Kentucky. The detailed sourcing rules are set forth in KRS 141.120 and administrative regulation 103 KAR 16:270, which applies to tax years beginning on or after January 1, 2018.

Tangible personal property

Receipts from sales of tangible personal property are sourced to Kentucky if the property is delivered or shipped to a purchaser within Kentucky, regardless of the f.o.b. point or other conditions of sale. If the property is shipped from an office, store, warehouse, factory, or other place of storage in Kentucky and the taxpayer is not taxable in the state of the purchaser, the receipts are sourced to Kentucky.

Real property

Receipts from the sale, rental, lease, or license of real property are sourced to Kentucky if the real property is located in Kentucky.

Rental, lease, or license of tangible personal property

Receipts from rental, lease, or license of tangible personal property are sourced to Kentucky to the extent the property is located in Kentucky. For mobile property (such as equipment or vehicles) that moves both within and without Kentucky during the lease period, the receipts are apportioned using a mileage fraction under 103 KAR 16:290, adjusted as necessary to reflect differences between contract-period usage and taxable-year usage.

Services — general rule

Receipts from the sale of a service are sourced to Kentucky if and to the extent the service is delivered to a location in Kentucky. "Delivered to a location" means the location of the taxpayer's market for the service, which may not be the location of the taxpayer's employees or property performing the service.

In-person services

In-person services are those physically provided in person by the taxpayer (or by a third-party contractor on the taxpayer's behalf) when the customer or the customer's real or tangible property upon which the services are performed is in the same location as the service provider. These receipts are sourced to Kentucky if and to the extent the customer receives the in-person service in Kentucky. Examples include carpentry, certain medical and dental services, and child care services.

Professional services

Professional services of an intellectual or intangible nature—such as legal, accounting, financial, and consulting services—are sourced based on where the service is delivered to the customer, not where the service provider performs the work. The regulation requires the taxpayer to determine the location where the benefit of the service is received. If the customer is an individual, receipts are generally sourced to the individual's billing address. If the customer is a business, receipts are sourced to the location where the service is received, which ordinarily is the customer's commercial domicile unless the service relates to specific business operations at another location.

Receipts from intangible property

Certain receipts from the sale of intangible property are excluded from both the numerator and denominator of the receipts factor under KRS 141.120(11)(a)4.b.iii. For intangible property transactions that are included in the receipts factor, the regulation provides specific sourcing rules depending on the type of intangible (e.g., patents, copyrights, trademarks).

Throwout rule

If the taxpayer is not taxable in the state to which receipts would otherwise be assigned, or if the state of assignment cannot be determined or reasonably approximated, those receipts are excluded from the denominator of the receipts factor under KRS 141.120(11)(c).

Effective date

The market-based sourcing framework in KRS 141.120 and 103 KAR 16:270 applies to tax years beginning on or after January 1, 2018, the same effective date as Kentucky's adoption of the single-sales-factor apportionment formula.

Kentucky imposes a Limited Liability Entity Tax (LLET) under KRS 141.0401 on corporations and limited liability pass-through entities doing business in the state. A "limited liability entity" is defined in KRS 141.0401(1)(e) to mean a corporation or a limited liability pass-through entity. A "limited liability pass-through entity" under KRS 141.010(16) means a pass-through entity in which the partners, members, or shareholders have limited liability with respect to the entity's obligations—specifically including limited liability companies, limited partnerships, limited liability partnerships, and S corporations, but excluding general partnerships and sole proprietorships. The same "doing business" standard that triggers nexus for corporate income tax under 103 KAR 16:240 also creates LLET liability; no separate threshold applies.

Tax base and calculation

The LLET is calculated under two alternative methods, and the taxpayer pays the lesser of the two:

1. Gross receipts basis: 0.095% of Kentucky gross receipts (expressed in KRS 141.0401(2)(a)1. as $950 per $1 million), or
2. Gross profits basis: 0.75% of Kentucky gross profits (expressed in KRS 141.0401(2)(a)2. as $7,500 per $1 million).

Kentucky gross receipts are defined in KRS 141.0401(1)(a) as the numerator of the apportionment fraction under KRS 141.120 (the market-based receipts sourcing formula), and include the taxpayer's proportionate share of Kentucky gross receipts from all wholly or partially owned limited liability pass-through entities, including all layers of a multi-tiered pass-through structure. Gross receipts from all sources (the denominator) is defined in KRS 141.0401(1)(b) as the denominator of the apportionment fraction.

Kentucky gross profits are Kentucky gross receipts less Kentucky cost of goods sold. KRS 141.0401(1)(d) strictly limits what may be deducted as cost of goods sold: only costs directly incurred in acquiring or producing a tangible product for purposes of manufacturing, producing, reselling, retailing, or wholesaling may be included. The statute provides that "for an entity other than manufacturing, producing, reselling, retailing or wholesaling, no costs shall be included in cost of goods sold." As a result, service businesses, technology companies, and other non-manufacturing entities typically have no allowable cost of goods sold, meaning their Kentucky gross profits equal their Kentucky gross receipts for LLET purposes.

Small-business exemption and phase-in

If either total gross receipts from all sources or total gross profits from all sources is $3 million or less, the LLET is $175. This is the minimum tax amount under KRS 141.0401(2)(b).

For entities with total gross receipts or total gross profits between $3 million and $6 million, the tax phases in under a formula set forth in the statute. For gross receipts, the phase-in formula under KRS 141.0401(2)(a)1.a. is:

(Kentucky gross receipts × 0.00095) − [$2,850 × ($6,000,000 − total gross receipts from all sources) ÷ $3,000,000]

For gross profits, the phase-in formula under KRS 141.0401(2)(a)2.a. is:

(Kentucky gross profits × 0.0075) − [$22,500 × ($6,000,000 − total gross profits from all sources) ÷ $3,000,000]

In both cases, the result cannot be less than zero. Entities with both total gross receipts and total gross profits exceeding $6 million pay the full LLET at the rates above.

The $175 minimum applies to every taxable entity, regardless of size. Under KRS 141.0401(3), nonrefundable credits permitted by KRS 141.0205 may reduce the LLET, but the final LLET liability may not be reduced below $175 by any credit.

Interaction with corporate income tax

For a corporation subject to tax under KRS 141.040, the LLET paid generates a nonrefundable credit against corporate income tax. Under KRS 141.0401(3)(a), the credit equals the LLET calculated for the current year, minus any credits identified in KRS 141.0205 that were applied against the LLET, minus the $175 minimum, plus any credit attributable to LLET paid by wholly or partially owned limited liability pass-through entities (allocated proportionately to the corporate member). The credit may be applied only to the income tax due from the corporation's activities in Kentucky; any remaining credit is disallowed and does not carry forward.

For members, shareholders, or partners of a limited liability pass-through entity, KRS 141.0401(3)(b) provides a similar credit: the member's proportionate share of the entity's LLET (calculated after subtraction of any credits under KRS 141.0205 and reduced by the $175 minimum). Under KRS 141.0401(3)(b), the LLET credit allowed to a member "shall be applied to the income tax imposed by KRS 141.020 or 141.040 on income from the limited liability pass-through entity," and any remaining credit from the pass-through entity is disallowed.

This credit structure prevents double taxation: entities pay LLET at the entity level (calculated on gross receipts or gross profits, an economic base distinct from net income), then receive a credit against net income tax to the extent that credit does not exceed the income tax attributable to the same activity.

Intercompany eliminations for combined/unitary returns

When a corporate taxpayer is part of a unitary combined group filing a combined return for corporate income tax and LLET (using Form 720U), Kentucky requires that intercompany transactions—including receipts and profits—between group members are eliminated for purposes of determining both the LLET gross receipts and gross profits base. This treatment is confirmed by official administrative regulation and Kentucky DOR filing instructions. Specifically, the regulation governing combined unitary groups states: "The designated filer shall remit the tax imposed on the combined Kentucky net income and receipts of the combined group" (103 KAR 16:400 Section 2(2)), which means group-level eliminations apply when determining Kentucky gross receipts and profits subject to LLET. DOR instructions for the Kentucky Unitary Combined return further specify that intercompany transactions are eliminated in both income and gross receipts calculations. Each group member does not separately include such intercompany amounts in its own LLET base.

For affiliated groups filing a Kentucky consolidated return (under KRS 141.201), eliminations of intercompany transactions are required in line with federal consolidation principles (see KRS 141.201(4)(b)), and Kentucky uses similar eliminations for LLET base calculation at the group level.

Exemptions

KRS 141.0401(6) provides specific exemptions from LLET. For tax years beginning on or after January 1, 2021, exempt entities include:

• Financial institutions as defined in KRS 136.500 (subject to the bank franchise tax), except banker's banks organized under KRS 287.135 or 286.3-135;
• Insurance companies (subject to insurance premium tax);
• Organizations exempt under IRC Section 501(c);
• Religious, educational, charitable, and like corporations not conducted for profit;
• Publicly traded partnerships treated as partnerships under IRC Section 7704(a), and any partnership or limited liability company in which a publicly traded partnership or its affiliates directly or indirectly own any interest;
• Qualified investment partnerships as defined in KRS 141.0401(7);
• Public service corporations subject to tax under KRS 136.120; and
• Personal service corporations as defined in IRC Section 269A(b)(1), provided substantially all activities consist of services in the fields of health, law, engineering, architecture, accounting, actuarial science, performing arts, or consulting, and substantially all stock is held by employees performing such services.

Exemptions for financial institutions and insurance companies apply only for tax years beginning prior to January 1, 2021, under prior versions of the statute; those entities became subject to LLET beginning January 1, 2021, under 2020 Ky. Acts ch. 91, § 8.

Pass-through entities may also exclude the proportionate share of gross receipts or gross profits allocable to a "qualified exempt organization" under KRS 141.0401(7).

Effective date and history

The LLET was enacted by 2006 (1st Extra. Sess.) Ky. Acts ch. 2, § 4, effective June 28, 2006, replacing Kentucky's Alternative Minimum Calculation. Amendments in 2018 and 2020 established the current rate structure and tied the definitions of Kentucky gross receipts and gross profits to the single-sales-factor apportionment formula and market-based sourcing rules under KRS 141.120, which took effect for tax years beginning on or after January 1, 2018.

Caution / review status: Not yet human confirmed. Practitioners should review the most current official instructions and regulatory updates for each filing year, especially for group filings under KRS 141.201 (consolidated) or KRS 141.202 (unitary combined), as administrative/filing details can evolve.

Kentucky requires mandatory combined unitary reporting for corporations engaged in a unitary business with one or more other corporations for tax years beginning on or after January 1, 2019. Under KRS 141.202(3)(a), a taxpayer engaged in a unitary business must file a combined report that includes the income and apportionment fraction of all corporations that are members of the unitary business. This combined reporting requirement applies unless the corporation makes an election to file a consolidated return under KRS 141.201.

Unitary business definition and 50% ownership test

A "combined group" subject to mandatory combined unitary reporting includes only corporations for which the voting stock is more than 50% owned, directly or indirectly, by common owners. KRS 141.202(2)(a) establishes this 50% ownership threshold. The term "unitary business" is broadly construed to the extent permitted by the U.S. Constitution.

Under administrative regulation 103 KAR 16:400, a unitary business is characterized by significant flows of value evidenced by factors such as functional integration, centralization of management, and economies of scale. These factors provide evidence of whether business activities operate as an integrated whole or exhibit substantial mutual interdependence. The regulation requires analyzing these factors in combination for their cumulative effect, not in isolation.

Waters-edge basis

The combined report must be filed on a waters-edge basis under KRS 141.202(3)(a) and (8). This means the combined group generally includes only U.S. corporations and certain specified foreign corporations, excluding most foreign subsidiaries from the combined return.

Alternative consolidated return election under KRS 141.201

As an alternative to mandatory combined unitary reporting, an affiliated group may elect to file a consolidated return that includes all members of the affiliated group. Under KRS 141.201(4)(a), an affiliated group—whether or not filing a federal consolidated return—may elect to file a Kentucky consolidated return which includes all members of the affiliated group.

The "affiliated group" for this purpose is defined by reference to the federal definition: corporations connected through stock ownership with a common parent corporation where the common parent directly owns at least 80% of voting power and value of at least one includible corporation, and stock meeting the 80% test of each includible corporation (other than the common parent) is directly owned by one or more other includible corporations.

Binding election period

Once made, the consolidated return election is binding on both the Department of Revenue and the affiliated group for a period beginning with the first month of the first taxable year for which the election is made and ending with the conclusion of the taxable year in which the 48th consecutive calendar month expires. This 48-month binding period is specified in KRS 141.201(2)(e). The election must be made on a form prescribed by the Department and submitted on or before the due date of the return, including extensions, for the first taxable year for which the election is made.

Treatment of consolidated group

Under KRS 141.201(4)(b), an affiliated group electing to file a consolidated return is treated for all purposes as a single corporation. The determinations and computations required are made in accordance with Internal Revenue Code Section 1502 and related regulations, except as required by differences between Kentucky law and the Internal Revenue Code. All intercompany transactions between corporations included in the consolidated return are eliminated in computing net income and determining the apportionment fraction.

Effective date

Both KRS 141.201 and KRS 141.202 apply to taxable years beginning on or after January 1, 2019. Prior to January 1, 2019, Kentucky required consolidated returns for affiliated groups under former KRS 141.200, but did not provide for combined unitary reporting. The 2018 legislation (House Bill 486) enacted mandatory combined unitary reporting and the consolidated return alternative for the first time, effective January 1, 2019.

Kentucky permits corporations to carry forward net operating losses (NOLs), but not carry them back, and has detailed provisions for NOL usage and allocation under group filings and restructuring events.

Kentucky NOL Carryforward and Utilization Rules

• NOLs from tax years before January 1, 2018, may be carried forward up to 20 years (KRS 141.011(7)).
• For losses from tax years on or after January 1, 2018, NOLs may be carried forward indefinitely, but annual use is capped at 80% of taxable income for that year (KRS 141.011(8)). No carryback of NOLs is permitted.

Group Filing—Combined/Consolidated NOL Sharing Limits

• For unitary combined groups (mandatory since Jan. 1, 2019), KRS 141.202(8) and 103 KAR 16:250 Section 4 allow sharing of NOLs. However, no group member’s Kentucky net income can be reduced by more than 50% in any year using NOLs apportioned from other group members. NOLs used by a group member reduce the origin member’s NOL carryforward under FIFO rules.
• For pre-2019 consolidated returns, KRS 141.200(11)(b) limits the aggregate NOL deduction to 50% of the Kentucky net income of members who did not sustain a loss that year.

NOLs in Group Restructurings (Mergers, Acquisitions, Departures)

• 103 KAR 16:250 Section 3 describes NOL allocation when a member ceases Kentucky nexus or leaves a filing group. For each loss year, the pre-apportioned NOL is allocated among entities in proportion to their share of the loss. Each departing member must have had Kentucky nexus in the loss year to retain a share. Apportionment is based on the original loss year’s apportionment factor.

Federal IRC § 382 and § 384 Limitations—State (Non)Conformity

• Kentucky law is silent regarding the adoption or application of the federal IRC § 382 ownership change limitation and § 384 asset acquisition limitation on NOL usage.
• Neither the Kentucky Revised Statutes nor Kentucky administrative regulations explicitly incorporate IRC § 382 or 384 limitations for Kentucky corporate income tax purposes, even though Kentucky uses IRC conformity for many aspects of the tax base. Kentucky DOR regulations on NOLs (103 KAR 16:250) address allocation and usage rules under state law but do not reference or import the federal § 382 or § 384 limitations for Kentucky tax purposes.
• As a result, unless Kentucky law or regulation is amended or DOR publishes future guidance, there is no Kentucky statutory, regulatory, or official Departmental limitation mirroring IRC § 382 or § 384 for NOL use in merger or change-of-control scenarios. Practitioners should confirm status for each filing year, as legislative or administrative guidance could change.

Tax Credits in Group Restructuring

• Kentucky law does not prescribe rules for the transfer or succession of corporate income tax credits (including LLET credits) upon entity departures, mergers, or acquisitions. Credits generally do not transfer unless authorized in the enabling statute.

Kentucky provides a set of statutory credits that may be used to reduce corporate income tax and Limited Liability Entity Tax (LLET) liabilities for qualifying businesses. These credits are strictly limited to those authorized by statute, primarily found in KRS Chapter 141 and specific provisions of KRS Chapter 154, and are subject to change via legislative amendment. The scope of this section is limited to credits that may be claimed against Kentucky corporate income tax and/or LLET. Credits available solely for other state taxes (e.g., property, sales/use, or motor fuels) are not addressed here.

Credit categories and principal statutes Kentucky’s business tax credits include incentives for investment, job creation, workforce training, technology, energy, coal, and other targeted activities. Major credits (current as of mid-2024) include:

• Kentucky Investment Fund Act (KIFA) Credit: For equity investments in state-certified investment funds (KRS 154.20-258 et seq.).
• Kentucky Reinvestment Act (KRA) Credit: For qualifying reinvestment projects intended to maintain or increase Kentucky employment (KRS 154.34-120 to 154.34-140).
• Job Development Credit (JDC): Incentive for businesses creating new jobs through expansion or location (KRS 154.24-110 to 154.24-120).
• Skills Training Investment Credit: For eligible costs of employee training (KRS 154.12-2084).
• Coal Incentive and Tax Credit: For the processing, use, or transportation of Kentucky coal—including KRS 141.0405, 141.428, 141.430.
• Film Industry Credit: For qualified production expenditures in Kentucky (KRS 141.383).
• Angel Investor Credit: For investments in certified small businesses (KRS 141.396, 141.397).
• Renewable/alternative energy, recycling, R&D, and other activity‑specific credits: See relevant KRS sections.

NEW: Qualified Broadband Investment Tax Credit (effective Jan 1, 2025) A new nonrefundable, nontransferable credit is available for taxable years starting January 1, 2025, through December 31, 2028, for corporate taxpayers and LLET filers that make qualified broadband equipment purchases. The credit equals 50% of the Kentucky sales and use tax paid (net of seller reimbursements) on qualified broadband property and applies against the Kentucky corporate income tax and LLET. There is a $5 million statewide annual cap. Taxpayers must apply to the Department of Revenue by December 31 after the investment year; approved credits are allocated by February 1 of the following year. See KRS § 141.391 and instructions for Form PTE. This program was enacted as part of HB 8 (2024 Regular Session).

General features and limitations

• Features such as credit caps, refundability, pre-approval, and carryforward periods vary by individual credit and are controlled by the authorizing statute. Most credits are nonrefundable, and many require timely application and supporting documentation.
• Credits such as the KRA, JDC, KIFA, Film, and Broadband credits require pre-approval or application through state agencies (e.g., Kentucky Cabinet for Economic Development or Department of Revenue). Consult the relevant KRS section and DOR guidance for procedures.
• The Kentucky Department of Revenue maintains a summary Business Incentive and Tax Credit Programs page with descriptions and links to underlying statutes, forms, and schedules.

How to confirm eligibility and current credits Review the cited KRS sections and the Department of Revenue program page and current-year forms/instructions to confirm the availability and details for each credit for the relevant filing year. Statutory amendments and new credits occur regularly; always check for updates as of the applicable tax year.

Kentucky requires every corporation, limited liability entity (LLE), and pass-through entity (PTE) subject to the corporate income tax or Limited Liability Entity Tax (LLET) to file an annual Kentucky return using the appropriate form. For calendar-year taxpayers, returns are due on or before the 15th day of the fourth month following the close of the taxable year (typically April 15). If the statutory due date falls on a weekend or state holiday, the return is due on the next business day.

The main filing forms are:

• Form 720: Corporation Income and LLET Return (C corporations)
• Form 720S: S Corporation Income and LLET Return
• Form 765: Partnership Return of Income

A Kentucky return is required even if no tax is due for the year. Payment in full is due by the original return due date. Interest (KRS 131.183) and penalties (KRS 131.180) apply to late payments and late filings.

Extensions: Kentucky grants an automatic extension of time to file, but not to pay. The extension period granted by Kentucky matches the period granted under the federal extension (via IRS Form 7004). The Department of Revenue accepts either a copy of the timely filed federal extension (IRS Form 7004) or Kentucky Form 720EXT, but the taxpayer must submit the extension request by the original due date of the return. If using the Kentucky form, estimated payment of tax due should accompany the extension to avoid interest and late payment penalties. If a federal extension is not obtained, a Kentucky-specific extension can be requested on Form 720EXT. The extension gives additional time to file the return only—payment is still due by the regular deadline.

All authority for deadlines and extensions is set by KRS 141.160 and elaborated in 103 KAR 15:050. The Kentucky DOR's published corporate and PTE FAQs and guidance confirm forms and procedures.

Kentucky requires corporations and limited liability entities (as defined in KRS 141.0401) to make estimated tax payments if the combined Kentucky corporate income tax and Limited Liability Entity Tax (LLET) liability for the taxable year is expected to be $5,000 or more, after reduction by allowable credits. This obligation applies to C corporations and to limited liability pass-through entities for their LLET liabilities. S-corporations generally pay only LLET, not corporate income tax, except to the extent addressed by specific provisions in Kentucky law.

Installment schedule and required payments

Estimated tax must be paid in four installments during the taxable year. The due dates are:

• 15th day of the fourth month (typically April 15 for calendar-year filers)
• 15th day of the sixth month (June 15)
• 15th day of the ninth month (September 15)
• 15th day of the twelfth month (December 15)

Each installment is generally 25% of the required annual payment. The annual payment required is the lesser of:

• 100% of the prior year’s total tax liability (corporate income tax + LLET), if the prior year was a full 12-month tax year and a Kentucky return was filed, or
• 100% of the current year’s estimated liability.

Taxpayers may use Kentucky Form 720-ES and the accompanying instructions to determine and submit payments. For new taxpayers or those not filing a 12-month prior-year return, only the current year’s liability calculation applies. Under KRS 141.044(5), taxpayers may elect to annualize income using a schedule similar to federal estimated tax computations, and special rules apply for farmers and fishermen as set out in the statute.

Penalties and interest

If the required estimated installments are not paid timely or in sufficient amount, Kentucky imposes penalties and interest as provided under KRS 131.180 (penalties for underpayment) and KRS 131.183 (interest on late payments or underpayments). Each required installment is considered separately for penalty calculations.

Exemptions and special cases

Estimated payments are not required for entities whose combined corporate income and LLET tax liability for the current year is less than $5,000. The statute specifically describes applicability and computation and should be reviewed for special cases such as short periods, annualization, or farmers/fishermen exceptions.
