What Is the Arkansas Income Tax Calculator?

The Arkansas income tax calculator estimates the state income tax on your Arkansas return from your federal adjusted gross income. Arkansas uses a flat 3.9% rate for 2024 and 2025, then switches to graduated brackets topping at 3.7% for 2026, so the main work is finding your Arkansas taxable income before the rate is applied. The estimate is a planning figure, not the final line on Form AR1000F.

  • Year-end planning: See what a raise or a new deduction does to your Arkansas liability before you file Form AR1000F.
  • Comparing filing options: Check how married filing jointly versus separately changes the standard deduction and the tax.
  • Validating withholding: Compare the annual state tax here against the Arkansas withholding taken from your paychecks during the year.

Arkansas builds its taxable income from your federal AGI, then subtracts Arkansas additions and subtractions and the Arkansas standard or itemized deduction. The federal AGI is the bridge between the two returns, which is why this calculator starts there. If you need to find that starting number first, the AGI calculator walks through how federal AGI is built.

Because the 2024 and 2025 rate is a single 3.9% and the 2026 schedule is graduated, the state piece of your return depends on the year you pick. The flat years keep the math linear, while 2026 rewards lower income with a 0% bottom bracket.

How the Arkansas Income Tax Calculator Works

The calculator turns your federal AGI into Arkansas taxable income, picks the larger of your standard or itemized deduction, subtracts any Arkansas subtractions, and then applies the 3.9% flat rate for 2024/2025 or the 2026 graduated brackets.

arTaxable = max(0, federalAGI - deduction - otherArkansasSubtractions); arTax = arTaxable x rate (3.9% flat for 2024/2025, graduated brackets for 2026)
  • Federal AGI: Your federal adjusted gross income, carried from your federal return as the starting point for Arkansas taxable income.
  • Deduction used: The Arkansas standard deduction, or your itemized deductions if they exceed the standard amount for your filing status and tax year.
  • Other Arkansas subtractions: Amounts Arkansas lets you remove from AGI, such as exempt Social Security benefits, military pay, and the first $6,000 of eligible retirement-plan income.
  • Arkansas tax: 3.9% of positive Arkansas taxable income for 2024/2025, or the graduated bracket result for 2026.

Worked example: A 2026 head-of-household filer with $80,000 AGI and a $6,000 subtraction has taxable income of $80,000 - $2,470 - $6,000 = $71,530. The 2026 bracket tax is $609.58 plus 3.7% of ($71,530 - $26,400) = $609.58 + $1,669.81 = $2,279.39, an effective rate of 2.85% of AGI. For comparison, the same filer in 2025 would owe 3.9% of $71,530, or $2,789.67, because the flat year has no 0% bottom bracket and a higher top rate.

According to the Arkansas Department of Finance and Administration - Individual Income Tax, the 2024 and 2025 rate of 3.9% was set by Act 1 of the Second Extraordinary Session of 2024, and the 2026 graduated schedule is published in the DFA estimated-tax form.

The 2026 Arkansas brackets are 0% up to $5,599, 2.0% to $11,199.99, 3.0% to $15,999.99, 3.4% to $26,399.99, and 3.7% above $26,400 of net taxable income, as published in the Arkansas 2026 Tax Rate Schedule (DFA Form AR1000ES). If you want to see how the federal side is taxed before this state layer, the federal income tax calculator applies the federal brackets to the same AGI.

Key Concepts Explained

A few terms decide almost everything about your Arkansas result.

Federal AGI

Adjusted gross income from your federal return. Arkansas starts here, then layers state additions, subtractions, and the deduction on top.

Flat 3.9% vs 2026 brackets

Arkansas charges 3.9% on all Arkansas taxable income for 2024 and 2025, then a graduated schedule (0%, 2.0%, 3.0%, 3.4%, 3.7%) for 2026.

Standard vs itemized deduction

Arkansas uses a standard deduction indexed each year. You take itemized deductions only when they exceed the standard amount for your filing status.

Arkansas subtractions

Certain federal income is removed again on the Arkansas return, including exempt Social Security benefits and the first $6,000 of eligible retirement-plan income, lowering Arkansas taxable income.

The per-paycheck version and the annual return are two views of the same law. The Arkansas paycheck calculator shows the withholding taken from each check, while this tool shows the total annual liability on the return.

For retirees, the subtraction rules matter more than the rate. Because Social Security and the first $6,000 of eligible retirement-plan income are removed before the rate is applied, a retiree living on Social Security alone can have zero Arkansas taxable income even with a modest pension. Entering those subtractions is what keeps the estimate aligned with Form AR1000F rather than with a simple rate-times-AGI guess.

How to Use This Calculator

You only need the numbers already on your federal return and a sense of your deductions.

1

Pick the tax year: Choose 2024, 2025, or 2026 so the correct rate and indexed standard deduction are applied.

2

Choose your filing status: Select the status that matches your Arkansas return; it sets the standard deduction amount.

3

Enter federal AGI: Type your federal adjusted gross income from your federal Form 1040.

4

Add subtractions and itemized deductions: Enter any Arkansas subtractions and your itemized deductions if they exceed the standard amount.

Practical example: A 2025 single filer with $60,000 AGI and no subtractions owes about $2,244 after the $2,470 standard deduction at the 3.9% rate.

If your itemized deductions are smaller than the standard deduction, leave that field at 0; the calculator automatically uses the larger of the two. The federal child tax credit and other credits reduce your federal bill, not your Arkansas tax, but they are worth tracking alongside this estimate using the child tax credit calculator.

Benefits of Using This Calculator

  • Clear state liability: You see the exact Arkansas tax from your AGI without reading rate tables.
  • Filing-status comparison: Switching between married filing jointly and separately shows the deduction and tax difference immediately.
  • Year-to-year view: You can compare the 3.9% flat years against the 2026 graduated brackets to see how a rate change moves your bill.

Filing status can move the standard deduction a long way, especially for married couples. The marriage penalty calculator shows how federal brackets interact with joint versus separate filing, which is useful context before you decide how to file in Arkansas.

Because 2024 and 2025 are flat, the calculator is also a quick what-if tool for those years: raise AGI by $1,000 and state tax rises by $39, after the deduction. For 2026 the rise is smaller at lower incomes because of the 0% bottom bracket.

The Arkansas income tax calculator is most useful when you revisit it after a life change such as marriage, a new job, or starting Social Security, since each one shifts the deduction or a subtraction.

Pairing the annual estimate with your paystub also tells you whether you are on track for a refund or a balance due. If the withholding taken across the year is below the estimate here, you may want to adjust your AR4EC allowances; if it is above, you have been lending the state interest-free and could reduce withholding.

Factors That Affect Your Results

Tax year

2024/2025 use a flat 3.9%; 2026 uses graduated brackets topping at 3.7%, so the same income is taxed differently across years.

Filing status

Sets the standard deduction: married filing jointly roughly doubles the single/head-of-household amount, cutting taxable income and tax.

Arkansas subtractions

Each subtraction dollar lowers Arkansas taxable income by a full dollar, then the applicable rate lowers tax by 2.0% to 3.9% on that dollar.

This tool estimates the base Arkansas tax and excludes any credits, Arkansas additions, and local taxes (Arkansas has no local individual income tax). Final liability is on Form AR1000F. The 2026 standard deduction shown uses the 2025 indexed amount as the most recent published figure; the 2026 full-year form may index it slightly higher.

If you want to compare Arkansas with another state, the Arizona income tax calculator applies that state's flat rate to a similar AGI-based base, which makes the structures easy to line up side by side. The Arkansas income tax calculator is a planning estimate, so treat a real return as the final word where credits or additions apply.

According to IRS Publication 17, adjusted gross income is the federally defined starting point that states such as Arkansas build taxable income from.

Frequently Asked Questions

What is Arkansas's state income tax rate?

Arkansas uses a flat 3.9% individual income tax rate for 2024 and 2025. For 2026 it shifts to a graduated schedule with brackets of 0%, 2.0%, 3.0%, 3.4%, and a top rate of 3.7% on net taxable income. The rate that applies depends on the tax year you choose.

How is Arkansas taxable income calculated from federal AGI?

Arkansas starts with your federal adjusted gross income, applies any state additions and subtractions, then subtracts the Arkansas standard or itemized deduction. The result is Arkansas taxable income, and the state tax is the 3.9% flat rate (2024/2025) or the 2026 graduated brackets applied to that amount.

What is the Arkansas standard deduction for 2024, 2025, and 2026?

The indexed standard deduction is $2,410 (single/head of household) and $4,820 (married) for 2024; $2,470 and $4,940 for 2025; and $2,470 and $4,940 for 2026. Married filing jointly receives the married amount.

Does Arkansas have local or city income taxes?

No. Arkansas cities and counties do not levy a local individual income tax, so the state rate is the only income tax layer for Arkansas residents. This calculator estimates state income tax only.

Are Social Security benefits taxed by Arkansas?

Arkansas exempts Social Security benefits from state tax, along with VA benefits, Workers' Compensation, and Railroad Retirement benefits. If that applies to you, enter the exempt amount under other Arkansas subtractions.

How does the Arkansas estimate differ from my Arkansas paycheck withholding?

Paycheck withholding is taken per period using your Form AR4EC settings, while this calculator shows the total annual liability on your return. The Arkansas paycheck calculator covers the per-period withholding view; this tool covers the annual return.
