Yes, franchise tax is deductible on your federal return. If the tax is tied to running your business, you deduct it as an ordinary business expense on the entity’s return; if it isn’t, you claim it on Schedule A as part of your state and local tax deduction, where the SALT cap applies. A C-corporation deducts it dollar-for-dollar against taxable income. An individual claiming it personally runs into the SALT cap, set at $40,400 for 2026 for most filers.
Why Franchise Tax Qualifies as a Deduction
Two Internal Revenue Code sections do the work. Section 162 allows a deduction for all ordinary and necessary expenses paid in carrying on a trade or business, and a mandatory state franchise tax fits that description cleanly.1Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Section 164 then specifically confirms that state and local taxes not otherwise listed remain deductible when paid in carrying on a trade or business.2Office of the Law Revision Counsel. 26 USC 164 – Taxes
For a C-corporation, the deduction happens at the entity level and reduces taxable income before the 21 percent federal corporate rate applies. For pass-through entities (partnerships, S-corporations, single-member LLCs), the deduction reduces the entity’s net ordinary income, and that lower figure flows through to each owner’s Schedule K-1. Because the deduction lands at the business level, it isn’t subject to the personal SALT cap.
One point worth flagging: some states impose a minimum franchise tax even when the business earns nothing. That minimum is still fully deductible as a business expense, because what matters federally is whether the charge is an ordinary cost of operating, not whether it’s proportional to earnings.
Where to Report Franchise Tax by Business Type
The right form depends entirely on how your business is organized. Report it in the wrong place and you can lose the deduction or invite processing questions.
- C-corporations file Form 1120 and report franchise tax on Line 17, “Taxes and licenses.” The instructions cover taxes paid or accrued in your trade or business, excluding federal income taxes and anything already captured elsewhere on the return.3Internal Revenue Service. Instructions for Form 1120 (2025) – Section: Deductions
- S-corporations file Form 1120-S and report on Line 12, also “Taxes and licenses,” under parallel rules.4Internal Revenue Service. Instructions for Form 1120-S (2025) – Section: Deductions
- Partnerships file Form 1065 and report on Line 14, “Taxes and licenses.” The deduction reduces ordinary business income before it flows to each partner’s K-1.5Internal Revenue Service. Instructions for Form 1065 (2025) – Section: Deductions
- Sole proprietors and single-member LLCs use Schedule C, Line 23, “Taxes and licenses.” Because this reduces your net business profit before self-employment tax, the deduction saves you income tax and the 15.3 percent self-employment tax on that amount.6Internal Revenue Service. Instructions for Schedule C (Form 1040) (2025) – Section: Line 23
- Individuals with a franchise tax that isn’t tied to a business report it on Schedule A under state and local taxes, where the SALT cap applies.7Internal Revenue Service. Instructions for Schedule A (Form 1040) (2025)
One caution: never report the same franchise tax on both a business form and Schedule A. If it’s a business expense, it belongs on the business form only. Double-reporting is the kind of error that draws audit attention.
How the SALT Cap Limits a Personal Deduction
When a franchise tax doesn’t qualify as a business expense and instead falls under itemized deductions, the state and local tax cap limits how much you can actually deduct. The Tax Cuts and Jobs Act originally set that cap at $10,000, but the One Big Beautiful Bill Act raised it beginning with the 2025 tax year. For 2026, the cap is $40,400 for most filers and $20,200 for married individuals filing separately, with a 1 percent annual inflation adjustment.
There’s an income phase-down. Taxpayers with modified adjusted gross income above $505,000 ($252,500 for married filing separately) in 2026 see the cap shrink. The $40,400 limit is reduced by 30 percent of the amount your income exceeds the threshold, but it never drops below $10,000. A single filer earning $600,000, for example, sees the cap fall by roughly $28,500, landing at the $10,000 floor.
The cap covers everything in one bucket: state income or sales taxes, real property taxes, personal property taxes, and any franchise taxes claimed personally. If property taxes alone consume most of the cap, there’s little room left for franchise tax to add federal savings. That’s the practical reason to classify franchise taxes as business expenses whenever legitimately possible. A business deduction faces no cap.
The higher cap is temporary. It reverts to $10,000 ($5,000 for married filing separately) in 2030, with no income phase-down at that point.
The Pass-Through Entity Tax Workaround
If you own a partnership or S-corporation, most states now offer a pass-through entity tax (PTET) election that lets the business pay state income tax at the entity level rather than passing the obligation to owners. Because the SALT cap applies to individuals and not to businesses, shifting the payment to the entity converts it into a fully deductible business expense on the federal return.
IRS Notice 2020-75 confirmed that entity-level state tax payments are allowed as a deduction in computing the entity’s non-separately stated income, and that those payments are not subject to the individual SALT cap for partners or shareholders.8Internal Revenue Service. IRS Notice 2020-75 – Deductibility of Payments by Partnerships and S Corporations for State and Local Income Taxes To prevent double taxation, the state gives each owner a credit on their personal return equal to their share of the entity-level tax. Total state tax stays the same, but the federal deduction moves off Schedule A (where it would be capped) and onto the business return (where it isn’t).
The election is made by the entity, not by individual owners, and each state has its own deadline and procedures. For owners paying meaningful state taxes, it’s worth an annual conversation with your accountant. Missing the election when it’s available is one of the more expensive oversights in pass-through planning.
When to Claim the Deduction: Cash vs. Accrual
Your accounting method decides which year gets the deduction. Cash-basis taxpayers claim the franchise tax in the year they pay it. Write the check in December 2026, and it belongs on the 2026 return.
Accrual-basis taxpayers face a more complicated rule. Under Section 461(h), a tax liability isn’t treated as incurred until “economic performance” happens, and for taxes, economic performance means actual payment.9Office of the Law Revision Counsel. 26 USC 461 – General Rule for Taxable Year of Deduction The recurring-item exception softens that. If the franchise tax is a recurring item and you consistently treat it this way, you can deduct it in the year the liability becomes fixed and determinable, as long as payment occurs within 8½ months after that year’s close.10eCFR. 26 CFR 1.461-4 – Economic Performance
Most businesses paying annual franchise taxes meet this exception without difficulty. The liability is fixed by year-end, the amount is determinable, it recurs every year, and payment falls well within the 8½-month window. Apply the same method consistently from year to year; switching back and forth invites scrutiny.
When a “Franchise Tax” Isn’t Really a Tax
Not every charge a state labels a “franchise tax” qualifies as a deductible tax federally. The IRS applies its own criteria regardless of the state’s label. Revenue Ruling 2025-4 draws the line: a deductible tax is a mandatory charge imposed by a government to raise general revenue, while a fee is a charge for a specific service, benefit, or regulatory privilege provided to the payer.11Internal Revenue Service. Revenue Ruling 2025-4
Most franchise taxes clear this test. They’re imposed broadly on business entities, calculated on factors like net worth or capital, and the revenue funds the state’s general operations. But some states bundle regulatory charges, filing fees, or special assessments under the same label. If part of your payment is a flat charge for filing an annual report or maintaining a registered agent, that portion may not qualify as a tax under Section 164.2Office of the Law Revision Counsel. 26 USC 164 – Taxes It can still be deductible as an ordinary business expense under Section 162, but the classification on your return should reflect what the charge actually is.
Check your state’s franchise tax notice. If the charge is based on a percentage of assets, capital, or income, it’s almost certainly a tax. If it’s a flat amount for a specific state service, treat it as a business expense rather than a tax deduction. The practical difference is usually small since both reduce taxable income, but the classification matters if you’re audited.
How Long to Keep the Records
The IRS requires you to retain records supporting a deduction until the statute of limitations for that return expires. For most taxpayers, that means keeping franchise tax documentation for at least three years after filing the return that claimed the deduction.12Internal Revenue Service. How Long Should I Keep Records If you file early, the clock starts on the due date.
Your records should include the state’s assessment notice or return showing how the tax was calculated, proof of payment with the date visible, and documentation of which federal form and line you used. Accrual-basis taxpayers relying on the recurring-item exception should also keep records showing when the liability became fixed, so consistent treatment can be demonstrated if questioned.
Three years is the minimum. Underreport income by more than 25 percent and the IRS gets six years, and there’s no statute of limitations at all for fraudulent returns or failure to file. Franchise tax records are small and easy to store digitally, so keeping them for at least six years is cheap insurance.13Internal Revenue Service.
