Arkansas Self-Employment Tax Calculator

Estimate SE tax, federal and state tax, and a quarterly estimated-payment amount on 1099/self-employment income

Estimate only — not tax advice. Self-employment tax is 15.3% (12.4% Social Security + 2.9% Medicare) on 92.35% of net SE income, with half of it deducted from federal taxable income. Assumes this is your only income for the year — if you also have W-2 wages, results will run high (see methodology below). Does not model the 20% Qualified Business Income deduction. The quarterly figure is an even 4-way split of annual liability, not the IRS's actual (unevenly spaced) estimated-payment due dates.

Arkansas Paycheck Calculator FAQ

What are Arkansas's income tax brackets for 2026?

Arkansas uses 5 marginal brackets ranging from 0% to 3.70%.

How much is take-home pay on $65,000 in Arkansas?

On a $65,000 gross salary, a single filer in Arkansas takes home roughly $52,369.66/year (about $4,364.14/month) after federal tax, FICA, and state tax.

What deductions does Arkansas apply before taxing my income?

Arkansas applies no standard deduction — the full rate applies to gross wages, before its marginal bracket schedule. See the "How Arkansas Paycheck Tax Is Calculated" section above for the exact formula.

Does this estimate change if I'm married or have dependents?

This calculator uses single-filer figures only (v1 scope). Married filing jointly typically uses different federal and Arkansas state brackets and a larger standard deduction — your actual take-home pay will differ. Dependents can also reduce federal withholding via the W-4. Check Arkansas Department of Finance and Administration's married-filing-jointly tables for a precise figure.

Methodology & Source

Arkansas state tax figures sourced from Arkansas Department of Finance and Administration (https://www.dfa.arkansas.gov/), citing Top rate cut to 3.7% retroactive to 2026-01-01. Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Arkansas's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.

Self-employment tax uses the statutory 15.3% rate (12.4% Social Security + 2.9% Medicare) on 92.35% of net self-employment income, with half of the SE tax deducted from federal taxable income above-the-line — per IRS Schedule SE (Form 1040) instructions, IRC §1401 and §164(f), 2026 edition. The 20% Qualified Business Income deduction (IRC §199A) is not modeled — it phases out by income and business type and is too state/entity-dependent to compute generically. This assumes the self-employment income is your only earnings for the year; if you also have W-2 wages, the Social Security wage-base cap and Additional Medicare threshold are actually based on your combined earnings, so this will overstate SE tax if you have significant wage income too.

This is an estimate based on standard single-filer federal, FICA, and AR state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors. Arkansas' low-income relief is baked into the 0% starter bracket rather than a separate standard deduction in this simplified model.
