Arkansas Income Tax Calculator 2026 – how it works
Arkansas state income tax is based on indexed tax tables that apply percentage rates to taxable income ranges, with adjustment constants calculated at the midpoint of each range. For estimation purposes, this calculator groups the published indexed ranges into a simplified marginal structure. The grouped ranges are: from 0 to 5,499 at 0.00%, from 5,500 to 10,899 at 2.00%, from 10,900 to 15,599 at 3.00%, from 15,600 to 25,699 at 3.40%, and income above 25,700 taxed at 3.90%. Under this approach, higher rates apply only to the portion of income within the corresponding range.
Examples
Example 1: If taxable income is 5,000, the portion from 0 to 5,000 is taxed at 0.00% under the grouped Arkansas rate structure. Example 2: If taxable income is 12,000, the portion from 0 to 5,499 is taxed at 0.00%, the portion from 5,500 to 10,899 is taxed at 2.00%, and the portion from 10,900 to 12,000 is taxed at 3.00%. Example 3: If taxable income exceeds 25,700, the portions within each lower range are taxed at their respective rates, and only the portion above 25,700 is taxed at 3.90% under the grouped structure.
Limitations and important notes
Results are simplified estimates and may not match a filed Arkansas return. Arkansas requires exact tax table calculations that include indexed ranges and adjustment constants. This calculator does not reproduce the full indexed table or midpoint adjustments and should be used for estimation and comparison purposes only. For official calculations, refer to Arkansas DFA tax tables and forms.
FAQs about Arkansas Income Tax Calculator 2026
Does this calculator exactly match Arkansas DFA tax tables?
No. Arkansas publishes indexed tax tables with narrow income bands and adjustment constants that must be matched exactly for official filings. This calculator groups those published ranges to provide an estimate and may not exactly match DFA tax table results.
Is Arkansas income tax progressive?
Yes. Arkansas applies progressively higher percentage rates to higher portions of taxable income. Although the state uses indexed tables, the overall structure applies higher rates only to income within higher ranges.
What is the highest Arkansas income tax rate?
The highest published Arkansas individual income tax rate is 3.90%, which applies to higher portions of taxable income under the indexed table system.
