How to Pay Arkansas State Income Tax
Where and how to pay Arkansas state income tax
Arkansas collects state income tax through the Department of Finance and Administration. You can pay online through their website, by mail, or through your employer's payroll system if you have taxes withheld. The online payment portal accepts credit cards, debit cards, and bank transfers. Payments made online are processed the same day if submitted before 8 p.m. Central Time on a business day.
If you prefer to mail a check, send it to the Arkansas Department of Finance and Administration with your tax return or a payment voucher. The address appears on the state tax forms and on the department's website. Mail payments take longer to process, so send them well before the deadline if you owe money.
Most employed people in Arkansas have taxes withheld automatically from their paychecks through their employer. Your employer sends that money directly to the state on your behalf. If you are self-employed or have income that is not subject to withholding, you may need to make quarterly estimated tax payments instead of one lump sum at tax time.
Key Takeaways
- Arkansas state income tax is due on the same date as federal income tax — April 15 in most years, unless that date falls on a weekend or holiday.
- You can pay online through the Department of Finance and Administration website, by mail, or through payroll withholding if your employer offers it.
- Online payments by credit card or debit card are processed the same day if submitted before 8 p.m. Central Time on a business day.
- Self-employed people and those with income not subject to withholding must make quarterly estimated payments four times per year.
- Late payments are subject to penalties and interest, which accrue from the original due date regardless of when you actually pay.
Arkansas tax rates and who has to pay
Arkansas taxes income at rates that vary by income bracket. The state has multiple tax brackets, and the rate you pay depends on your total income for the year. Unlike some states, Arkansas does not have a flat tax — the more you earn, the higher percentage you pay on income above each threshold.
You must file and pay Arkansas state income tax if you earned income in the state during the tax year, even if you do not owe federal income tax. This includes wages, self-employment income, rental income, and some types of investment income. If you lived in Arkansas for part of the year, you may owe tax on income earned while you were a resident.
Certain types of income are not taxed by Arkansas, including Social Security benefits, some retirement distributions, and military pay for active-duty service members. If your only income is from one of these sources, you may not owe state income tax even if you lived in Arkansas.
Deadlines and what happens if you pay late
Arkansas state income tax is due on April 15 in most years, the same date as federal income tax. If April 15 falls on a weekend or holiday, the deadline moves to the next business day. You can request an extension to file your return, which gives you until October 15 to submit your paperwork, but the extension does not extend the payment deadline — taxes are still due on April 15.
If you do not pay by the deadline, the state charges a failure-to-pay penalty of 0.5 percent per month, up to 25 percent of the tax owed. Interest also accrues on unpaid taxes at a rate set by the state each year. Both the penalty and interest are calculated from the original due date, not from the date you eventually pay. This means the longer you wait, the more you owe beyond the original tax bill.
If you cannot pay the full amount by April 15, you can still file your return on time and pay what you can. The penalty applies only to the unpaid portion, and you can arrange a payment plan with the state to pay the remainder over time. Contact the Department of Finance and Administration to discuss your options before the deadline if possible.
Quarterly estimated payments for self-employed and other taxpayers
If you are self-employed, own a business, or have income that is not subject to withholding, you must make quarterly estimated tax payments to Arkansas. These payments are due on April 15, June 15, September 15, and January 15 of the following year. Each payment covers one quarter of the year's expected tax liability.
To calculate your quarterly payment, estimate your total income for the year, subtract deductions, and divide the result by four. If your income varies throughout the year, you can adjust each quarterly payment based on what you actually earned in that quarter. The state provides a worksheet to help you calculate the correct amount.
Quarterly payments are made through the same online portal as regular tax payments. You can also mail a check with a payment voucher. If you underpay your quarterly estimates, you may owe a penalty when you file your annual return, even if you pay the full amount owed by April 15 of the following year.
Payment methods and processing times
The Arkansas Department of Finance and Administration accepts payments through several methods. Online payments through their website are the fastest option — credit cards, debit cards, and electronic bank transfers are all accepted. Online payments submitted before 8 p.m. Central Time on a business day are processed the same day.
Mailed checks should be sent to the address listed on your tax return or the state's website. Mail payments typically take 7 to 10 business days to process after they arrive at the department. If you are paying close to the deadline, mail is risky because the postmark date, not the receipt date, determines whether you are on time — but processing delays can still cause confusion.
Some employers offer payroll withholding, which is the most reliable method if you are employed. Your employer calculates the tax based on your W-4 form and sends the money to Arkansas automatically. This method requires no action on your part after you complete the W-4 with your employer.
What to do if you cannot pay by the deadline
If you owe Arkansas state income tax but cannot pay the full amount by April 15, contact the Department of Finance and Administration before the deadline. The state can set up a payment plan that allows you to pay the tax in installments over time. You will still owe penalties and interest on the unpaid balance, but a payment plan prevents additional penalties for non-payment.
Payment plans typically require a down payment and monthly installments. The exact terms depend on how much you owe and your ability to pay. The department may also place a lien on your property or garnish your wages if you do not follow the payment plan agreement.
If you are experiencing financial hardship, the state may be able to temporarily delay collection efforts while you work out a plan. This is not forgiveness of the debt — you still owe the full amount plus penalties and interest — but it can buy you time to arrange the money.
Refunds and overpayments
If you overpay your Arkansas state income tax through withholding or estimated payments, the state will refund the excess when you file your return. Refunds are typically issued within 30 to 60 days of the state receiving and processing your return. You can check the status of your refund on the Department of Finance and Administration website.
You can choose to have your refund deposited directly into your bank account or mailed as a check. Direct deposit is faster and more reliable. If you do not claim your refund within three years, the money goes to the state's unclaimed property fund, though you can still request it later.
Frequently Asked Questions
What if I moved out of Arkansas during the tax year?
You owe Arkansas state income tax only on income earned while you were a resident. If you moved out partway through the year, you file a part-year resident return and pay tax only on the income earned before you left. You may also owe tax to the state you moved to on income earned after you arrived there.
Can I pay my Arkansas taxes with a credit card?
Yes, the state accepts credit cards and debit cards through their online payment portal. Be aware that credit card payments may include a processing fee charged by the payment processor, which is added to your payment. Check the exact fee before you submit the payment.
What happens if I file late but pay on time?
You will owe a failure-to-file penalty in addition to any tax owed, even if you pay the tax by April 15. The failure-to-file penalty is typically 5 percent per month, up to 25 percent. Filing on time is important even if you cannot pay the full amount.
Do I have to pay Arkansas state income tax if I work in Arkansas but live in another state?
Yes, Arkansas taxes income earned within the state regardless of where you live. If you work in Arkansas and live in another state, you may owe tax to both states. Your home state may offer a credit for taxes paid to Arkansas to prevent double taxation, but you need to check your home state's rules.
How do I know if my withholding is correct?
Review your pay stub to see how much is being withheld for Arkansas state tax. If you consistently get a large refund or owe a large amount at tax time, your withholding may be off. You can adjust your withholding by submitting a new W-4 form to your employer at any time during the year.
