Arkansas has a state income tax, and you must file a return if your income exceeds the filing threshold for your filing status

Arkansas taxes wage income, self-employment income, investment income, and retirement distributions. The state uses a progressive tax system with rates that climb from 2% on the lowest bracket to 5.75% on the highest. Unlike some states, Arkansas does not exempt Social Security benefits from taxation, though you may be able to exclude a portion depending on your age and total income.

If you work in Arkansas or live there, you will owe state income tax on income earned in the state. If you moved to Arkansas during the year or moved away, you may file as a part-year resident. The state also taxes income earned outside Arkansas if you are a full-year resident.

Key Takeaways

  • Arkansas state income tax rates range from 2% to 5.75% depending on your income level and filing status.
  • You must file an Arkansas return if your gross income exceeds the threshold for your filing status, which varies year to year.
  • Social Security benefits are taxable in Arkansas if your combined income (adjusted gross income plus half your Social Security) exceeds certain limits.
  • Part-year residents who moved into or out of Arkansas during the tax year file a part-year resident return and pay tax only on income earned while residing in the state.
  • Military members stationed in Arkansas may be exempt from state income tax on military pay under federal law, but must still file to report other income.

Arkansas Income Tax Brackets and Rates for the Current Year

Arkansas uses six tax brackets. Your rate depends on your filing status (single, married filing jointly, married filing separately, or head of household) and your taxable income. The lowest bracket starts at 2% and the highest reaches 5.75%. Each bracket applies only to income within that range, so a higher bracket does not mean your entire income is taxed at that rate.

The income ranges for each bracket change annually. You will find the current year's brackets on the Arkansas Department of Finance and Administration website or in the instructions that come with Form AR1000 (the state income tax return). Do not use last year's brackets—income thresholds shift each year based on inflation adjustments.

Who Must File an Arkansas State Return

You must file if your gross income exceeds the filing threshold for your status. For most filers, the threshold is between $2,500 and $3,100, but this amount changes yearly and depends on whether you are single, married, head of household, or another status. Check the current year's Form AR1000 instructions to find the exact threshold that applies to you.

You must also file if you had Arkansas income tax withheld from your paychecks, even if your income falls below the threshold. Filing allows you to recover any overpayment. If you are self-employed, you must file if your net self-employment income is $400 or more, regardless of your other income.

Part-year residents—people who moved into Arkansas or out of Arkansas during the tax year—must file a part-year resident return. You report only the income you earned while living in Arkansas and pay tax only on that portion.

Income Types That Arkansas Taxes

Arkansas taxes wages, salaries, tips, and other compensation from employment. It also taxes self-employment income, rental income, capital gains, dividends, and interest. Retirement distributions from IRAs and 401(k)s are taxable. Pension income is taxable unless you meet specific age and income requirements that allow you to exclude a portion.

Social Security benefits are taxable in Arkansas if your combined income exceeds a threshold. Combined income means your adjusted gross income plus half of your Social Security benefits. If you are single and your combined income exceeds $25,000, some or all of your benefits become taxable. If you are married filing jointly, the threshold is $32,000. You calculate the taxable portion using a worksheet in the Form AR1000 instructions.

Certain income is not taxed by Arkansas. These include gifts, inheritances, life insurance proceeds paid due to death, and some scholarship and fellowship grants used for tuition and books. Military members may exclude military pay from Arkansas taxation if they are on active duty stationed in the state, though they must still file to report other income.

Deductions and Credits Available in Arkansas

Arkansas allows a standard deduction that varies by filing status and age. For the current year, the standard deduction ranges from approximately $2,500 to $3,700 depending on whether you are single, married, or over 65. You can claim the standard deduction or itemize deductions if itemizing produces a larger reduction in taxable income.

Arkansas offers a dependent exemption credit and a child and dependent care credit. The state also has credits for property tax paid, earned income (similar to the federal Earned Income Tax Credit), and contributions to certain savings accounts. Some credits are refundable, meaning you receive money back even if you owe no tax. Others reduce your tax liability only to zero.

If you pay income tax to another state on income earned there, you may be able to claim a credit for taxes paid to that state, though the credit cannot exceed your Arkansas tax liability. This prevents double taxation when you work in one state and live in another.

How to File Your Arkansas State Return

You can file on paper using Form AR1000 and related schedules, or you can file electronically. The Arkansas Department of Finance and Administration maintains a list of approved e-file providers. Many tax software programs include Arkansas returns in their standard packages. If you use a tax professional, they can file electronically on your behalf.

Paper returns are mailed to the Arkansas Department of Finance and Administration at the address shown in the Form AR1000 instructions. Electronic returns are typically processed faster and provide confirmation of receipt. The filing important date is the same as the federal important date, usually April 15, though it shifts if that date falls on a weekend or holiday.

If you cannot file by the important date, you can request an extension. File Form AR1000-EXT by the due date to extend your filing important date by six months. An extension gives you more time to file, but it does not extend the time to pay. If you owe tax, you should pay by April 15 to avoid penalties and interest, even if you have an extension.

What Happens If You Do Not File or Pay

If you owe Arkansas income tax and do not pay by the important date, the state charges interest and penalties. The failure-to-pay penalty is typically 0.5% of the unpaid tax per month, up to a maximum. Interest accrues daily at a rate set by the state each quarter. Both penalties and interest compound, so the longer you wait, the more you owe.

If you do not file a required return, the state can file a substitute return on your behalf using information from employers and other sources. This return usually results in a higher tax bill because it does not include deductions or credits you might claim. You can still file your own return later to correct the substitute return, but you will owe penalties for the late filing.

The Arkansas Department of Finance and Administration can place a lien on your property or garnish your wages to collect unpaid tax. If you owe and cannot pay in full, contact the department about a payment plan. The state may work with you to set up monthly payments rather than pursuing collection action.

Frequently Asked Questions

Do I have to pay Arkansas income tax if I work remotely for a company in another state?

If you live in Arkansas and work remotely, you owe Arkansas income tax on your wages. The state where your employer is located does not matter. You are taxed based on where you live, not where your employer operates. If you moved to Arkansas during the year and worked remotely before moving, you file as a part-year resident and pay tax only on income earned after you arrived.

Can I claim a credit for federal income tax paid?

No. Arkansas does not allow a credit for federal income tax. You can only claim a credit for income tax paid to another state. Federal tax and state tax are separate obligations, and paying one does not reduce what you owe the other.

What if I am retired and my only income is a pension?

Pension income is taxable in Arkansas unless you meet the age and income limits for the pension exclusion. If you are 59½ or older and your adjusted gross income does not exceed a certain amount, you may exclude up to $6,000 of pension income. Check the Form AR1000 instructions for the current income limit. If your pension is your only income and it falls below the filing threshold, you may not need to file, but filing could result in a refund if tax was withheld.

Do I need to file an Arkansas return if I only lived there part of the year?

Yes, if your income exceeds the filing threshold. You file as a part-year resident and report only income earned while you lived in Arkansas. You pay tax only on that portion of your income. Attach a statement to your return explaining when you moved in or out of the state.

What is the penalty for filing late?

The failure-to-file penalty is typically 5% of the unpaid tax per month, up to 25% total. If you file late but pay on time, the penalty is usually smaller. If you both file and pay late, both penalties explore. Filing an extension before the important date eliminates the failure-to-file penalty if you file by the extended important date, though the failure-to-pay penalty still applies if you did not pay by April 15.
