Arkansas Income
Tax Rates & Rules

Arkansas has a graduated individual income tax for 2026 with rates ranging from 0% to 3.9%. The state's official 2026 estimated-tax worksheet also lists a standard deduction of $2,470 per taxpayer. Arkansas income tax is based on net taxable income after applicable deductions rather than gross wages alone.

The 2026 rate schedule begins with a 0% band for net taxable income below $5,600. Marginal rates then rise through 2%, 3%, 3.4% and 3.9%. The maximum individual rate has remained 3.9% since the reduction enacted for tax years beginning in 2024.

What Is the Arkansas Income Tax Rate for 2026?

Arkansas uses a progressive tax schedule in 2026. A taxpayer does not pay 3.9% on every dollar of taxable income simply because their income reaches the top bracket.

The Arkansas DFA schedule uses base-tax amounts plus a percentage of income above each bracket threshold. It also contains a special table for a narrow upper-income range before the standard 3.9% formula resumes. For an exact tax calculation, use the current DFA rate schedule rather than multiplying all taxable income by the top rate.

How Is Arkansas Income Tax Calculated?

Arkansas income tax starts with income that must be reported to the state, applies Arkansas adjustments and deductions then calculates tax on net taxable income using the 2026 rate schedule.

• Determine Arkansas adjusted gross income.
• Subtract the Arkansas standard deduction or allowable itemized deductions.
• Determine net taxable income.
• Apply the applicable Arkansas tax rate schedule.
• Subtract eligible personal and other state tax credits.
• Compare final tax liability with withholding and estimated payments.

Arkansas Adjusted Gross Income - Deductions = Net Taxable Income

Income tax liability is different from paycheck withholding. Withholding is a prepayment collected during the year. The annual return reconciles those payments with the taxpayer's actual Arkansas income tax liability.

Arkansas Standard Deduction for 2026

The Arkansas standard deduction for 2026 is $2,470 per taxpayer according to the official 2026 estimated-tax worksheet.

Taxpayers who expect to itemize deductions use their estimated itemized amount instead. The standard deduction reduces net taxable income before the tax rate schedule is applied.

Does Arkansas Tax Capital Gains?

Arkansas taxes capital gains differently from ordinary income because current DFA guidance excludes part of qualifying net long-term capital gain from income while the remaining amount is treated as regular income.

Current Arkansas DFA guidance states that a portion of net long-term capital gains is excluded and directs taxpayers to Schedule AR1000D. DFA materials also identify a 50% exclusion for net long-term capital gains. Short-term gains do not receive the same treatment. In addition, Arkansas law provides an exemption for the portion of qualifying net capital gain above $10 million.

Because capital-gain rules depend on holding period, transaction type and the tax-year form, taxpayers with a significant gain should use the Arkansas schedule for the year they are filing rather than relying on a simple flat-rate estimate.

Who Pays Arkansas Individual Income Tax?

Arkansas residents generally report income under Arkansas individual income tax rules while nonresidents and part-year residents can have Arkansas filing obligations for Arkansas-source income.

Full-year residents generally use Form AR1000F. Part-year residents and nonresidents use Form AR1000NR when the filing requirements apply. Arkansas also has separate rules for military personnel, military spouses, pass-through entities and other special situations.

Arkansas Income Tax Withholding vs. Final Tax Liability

Arkansas withholding shown on a paycheck is an advance payment of state income tax, not the final annual tax calculation.

An employee can have too much or too little tax withheld depending on wages, Form AR4EC information, bonuses, multiple jobs and other income. The annual Arkansas income tax return compares actual tax liability with amounts already withheld or paid as estimates.

When Are Arkansas Estimated Tax Payments Required?

Arkansas generally requires estimated tax payments when a taxpayer reasonably expects estimated tax to exceed $1,000 and withholding or credits will not cover enough of the expected liability.

For 2026, Arkansas says the declaration is generally required if estimated tax is more than $1,000. To avoid an underestimate penalty, estimated payments should generally cover at least 90% of current-year tax or 100% of the prior year's tax when the prior return covered a full 12 months.

What Income Can Affect Arkansas Tax?

Arkansas taxable income can include wages and other income that is taxable under state law, but the state calculation can differ from the federal return because Arkansas has its own additions, subtractions, exemptions and credits.

• Wages and salaries
• Self-employment and business income
• Taxable interest and dividends
• Rental income
• Capital gains after Arkansas adjustments
• Certain retirement or pension income after applicable state rules
• Pass-through income

The exact treatment depends on the type of income and the current Arkansas form instructions. A state income tax page should therefore be used as a planning guide rather than a substitute for the return instructions.
