Income Tax in Arkansas: Complete Guide 2026

Tax information is for educational purposes only and does not constitute tax advice. Consult a licensed tax professional for your specific situation.

Arkansas uses a graduated individual income tax system with rates that have been trending downward in recent years as the state legislature has enacted a series of rate reduction packages. For 2026, the top marginal rate is projected to be approximately ~3.9%, down from higher levels in prior years. Arkansas groups taxable income into separate rate tables depending on the total amount of net income, creating a somewhat unusual structure where lower-income filers face a different bracket schedule than higher-income filers. Understanding which table applies to your situation is essential for accurate planning.

Arkansas Income Tax Rates (2026)

Arkansas applies different rate tables depending on total net income. The following reflects the projected high-income table for 2026:

Taxable Income Bracket	Marginal Rate
First ~$4,400	~2.0%
~$4,401 to ~$8,800	~4.0%
Over ~$8,800	~3.9%

Note: Arkansas’s top marginal rate is projected to drop to ~3.9% as part of ongoing rate reduction legislation. The lower bracket rate may exceed the top rate due to the structure of the separate rate tables.

Low-Income Rate Table

Taxable Income Bracket	Marginal Rate
First ~$5,100	~2.0%
~$5,101 to ~$10,200	~4.0%
Over ~$10,200	~3.9%

Filers with net income below approximately ~$24,300 may qualify for the low-income table, which provides wider brackets and slightly lower effective rates.

How Arkansas Income Tax Works

Filing Status and Income Tables

Arkansas does not follow the same filing status categories as the federal return in every respect. Married couples may file jointly or separately. The state determines which rate table applies based on total net income, which effectively creates a progressive system even within the graduated brackets.

Standard Deduction and Personal Credits

Arkansas offers a standard deduction of approximately ~$2,340 for single filers and ~$4,680 for married-filing-jointly filers. Additionally, there is a personal tax credit of approximately ~$29 per taxpayer and dependent. These figures are adjusted periodically.

Common Deductions and Adjustments

Retirement income: Arkansas exempts up to ~$6,000 of retirement income per person from state income tax, including pensions, 401(k) distributions, and IRA withdrawals.
Military retirement: Fully exempt from Arkansas income tax.
Social Security: Benefits are not taxed at the state level in Arkansas.
Federal income tax deduction: Arkansas is one of the few states that allows taxpayers to deduct a portion of their federal income tax liability from state taxable income, up to approximately ~$5,000 per filer.

Tax Credits

Child care credit: A percentage of the federal child and dependent care credit
Earned income credit: Approximately ~20% of the federal EITC
Political contributions credit: Up to ~$50 for qualifying contributions
Adoption credit: Available for qualifying adoption expenses
InvestArk credit: For qualifying investments in targeted businesses

Who Must File in Arkansas

You must file an Arkansas income tax return if:

You are a full-year resident with gross income exceeding the filing threshold for your filing status (approximately ~$14,398 for single filers)
You are a part-year resident or nonresident with Arkansas-source income
You owe additional taxes or want to claim a refund of withholding

Arkansas returns are due on April 15. The state conforms to most federal extension deadlines.

Comparison to National Average

State	Top Income Tax Rate	Structure
Arkansas	~3.9%	Graduated
Oklahoma	~4.75%	Graduated
Missouri	~4.8%	Graduated
Mississippi	~4.7%	Flat (phasing in)
Tennessee	~0%	No income tax
National average	~4.60%	Varies

Arkansas’s top rate of ~3.9% is projected to be competitive among its neighboring states. The ongoing rate reductions position the state as increasingly attractive for individuals and small businesses, though the multi-table structure adds complexity.

Tips for Minimizing Arkansas Income Tax

Claim the federal income tax deduction. Arkansas uniquely allows you to deduct up to ~$5,000 of your federal tax liability, a valuable benefit many filers miss.
Maximize retirement income exclusions. If you receive pension, IRA, or 401(k) income, ensure you exclude the first ~$6,000 per person from your Arkansas return.
Use the earned income credit. Arkansas offers a state EITC worth approximately ~20% of the federal credit, providing meaningful relief for working families.
Contribute to an Arkansas 529 plan. Contributions of up to ~$5,000 per person per year are deductible from Arkansas taxable income.
Review which rate table applies. Because Arkansas uses separate tables for different income levels, small changes in net income can shift you to a different table with different effective rates.
Deduct charitable contributions. Arkansas allows itemized deductions including charitable giving, which can reduce your taxable income if total deductions exceed the standard deduction.
File jointly when beneficial. Compare joint and separate filing outcomes, as the rate tables and deduction limits differ between statuses.
