Does Arkansas Have State Income Tax? Rates, Exemptions, Filing

Yes, Arkansas does have a state income tax. Individual income is taxed at graduated rates ranging from 2% up to 3.9% for 2026, which puts Arkansas among the lower-rate income tax states. The tax is governed primarily by Arkansas Code Title 26, Chapter 51.¹

Who Owes Arkansas Income Tax

Residents pay Arkansas tax on all income no matter where it was earned. Nonresidents and part-year residents only owe tax on income sourced from within the state. Full-year residents file Form AR1000F. Nonresidents and part-year residents file Form AR1000NR.²

2026 Tax Rates and Brackets

Arkansas uses a graduated bracket system, so different slices of your income are taxed at progressively higher rates. The bracket structure you use depends on your total net income, and the thresholds adjust for inflation each year.³

If your net income is roughly $92,300 or less, Arkansas applies a multi-bracket table with rates of 2%, 3%, 3.4%, and 3.9%. Most taxpayers in this range hit the top 3.9% rate once taxable income exceeds about $25,700. Above the $92,300 threshold, the structure collapses into two brackets: 2% on the first $4,600 and 3.9% on everything above that.³

Deductions and the Personal Credit

Your taxable income starts with gross income (wages, interest, dividends, business earnings, and most other sources), then you subtract adjustments and choose either the standard deduction or itemized deductions.⁴

For 2026, the standard deduction is $2,470 for single filers and heads of household, and $4,940 for married couples filing jointly. If deductible expenses such as medical costs, mortgage interest, and charitable donations exceed those amounts, itemizing produces a lower bill.³

After the tax is calculated, a personal credit reduces the bill dollar-for-dollar. For 2026, that credit is $29 per taxpayer ($58 for married filing jointly), plus $29 for each dependent.³

Retirement, Social Security, and Military Exemptions

Social Security benefits are completely exempt from Arkansas income tax. For other retirement income, the first $6,000 of taxable distributions from employer-sponsored plans or traditional IRAs is exempt per taxpayer. That $6,000 is a combined cap across all sources; you cannot stack $6,000 from a pension on top of $6,000 from an IRA.⁵ For traditional IRA distributions, you generally must have reached age 59½ to qualify, though distributions triggered by death or disability also count.⁶

Active duty service members receive an exemption on the first $9,000 of military pay and allowances. This applies to members of both the U.S. armed forces and the Arkansas National Guard. Military pay above $9,000 is taxed at the regular rates.⁷

Military retirement pay is fully exempt for tax years beginning in 2018 and after. There is one catch: if your military retirement exemption exceeds $6,000, you cannot also claim the separate $6,000 retirement exemption for a pension or IRA. If your military retirement income is under $6,000, you can use the remainder of the $6,000 exemption against other qualified retirement distributions.⁶

Filing and Paying

The standard filing deadline is April 15, or the next business day if that date falls on a weekend or holiday. You can file electronically through approved tax software or through the Arkansas Taxpayer Access Point (ATAP) portal, or mail a paper return.²

A federal extension filed on IRS Form 4868 is honored automatically by Arkansas, pushing the state filing deadline to November 15. You do not need a separate state form. If you need only a state extension, file Form AR1055 for an extension to October 15. An extension gives you more time to file, not more time to pay: interest and penalties still accrue from April 15 on any unpaid balance.²

Payments can be made online through ATAP using a bank account at no charge. Credit and debit card payments go through ACI Payments, Inc. and carry a convenience fee; card payments can be made at acipayonline.com or by phone at 1-800-272-9829 using jurisdiction code 1400.⁸ Checks and money orders mailed with a payment voucher are also accepted.

If you have income that is not subject to withholding, such as self-employment earnings, rental income, or investment gains, you likely need to make estimated quarterly payments to avoid underpayment penalties. The due dates track the federal schedule: April 15, June 15, September 15, and January 15 of the following year.⁹

Penalties and Interest If You’re Late

Missing the April 15 deadline triggers two penalties that run concurrently. The failure-to-file penalty is 5% of the unpaid tax for each month or partial month the return is late. The failure-to-pay penalty adds another 1% per month on the unpaid balance. Together they cap at 35% of the tax owed.¹⁰

On top of the penalties, Arkansas charges interest at 10% per year on unpaid tax, running from the original due date until the balance is paid.² A taxpayer who owes $5,000 and files six months late could face $1,750 in penalties plus $250 in interest before touching the underlying tax.

If You Can’t Pay in Full

The Arkansas Department of Finance and Administration offers two options for taxpayers who cannot pay the full balance.

A payment plan agreement spreads the debt (including penalties and interest) over monthly installments. Plans are not automatic; DFA reviews each request individually, files a Certificate of Indebtedness that functions as a lien while the plan is active, and continues to charge interest during the installment period. Missing a payment can trigger immediate collection action. To inquire, call 501-682-5000 or 1-800-292-9829.¹¹

For taxpayers who are genuinely insolvent, meaning expenses exceed income or liabilities exceed assets, the Offer in Compromise program may allow settlement for less than the full amount owed. All required returns must be filed before DFA will consider an application, and detailed financial documentation is required. Each case is evaluated on its own facts, and acceptance is not guaranteed. The Problem Resolution and Tax Information Office can be reached at 501-682-7751.¹¹
