Arkansas freelance rate & 1099 tax calculator

Arkansas income tax for freelancers in 2026

At a glance for 2026: 5 brackets from 0% to 3.7% (single filer), a $2,470 standard deduction, and quarterly estimated payments are required once you expect to owe tax.

Arkansas uses graduated rates up to 3.7%. The calculation starts from Arkansas’s own definition of income.

How Arkansas treats self-employment deductions

• Half of self-employment tax: not deductible. Arkansas computes its own AGI; the AR1000ADJ adjustment list does not include the deductible half of SE tax.
• Self-employed health insurance: deductible. Self-employed health insurance deduction is an allowed adjustment on Form AR1000ADJ.
• SEP-IRA / solo 401(k) contributions: deductible. KEOGH, self-employed SEP and SIMPLE plan contributions are allowed adjustments on Form AR1000ADJ.

How the calculator handles Arkansas

• Act 1 (HB1001) and Act 2 (SB1) of the 2026 First Extraordinary Session, signed May 6, 2026, cut the top individual rate from 3.9% to 3.7% for tax year 2026 and later. DFA's HB1001 fiscal impact statement gives the 2026 standard income table: 0% to $5,599, 2% $5,600-$11,199, 3% $11,200-$15,999, 3.4% $16,000-$26,399, 3.7% $26,400-$94,700. DFA had not posted official 2026 tax tables when checked (the 2026 AR1000ES worksheet still shows the pre-cut 3.9% schedule).
• Arkansas uses the same rate table for every filing status (joint filers apply it to combined income or may file separately on the same return).
• Above $94,700 of net taxable income Arkansas uses the upper income table (2026: 2% on the first $4,700 and 3.7% above, i.e. tax = 3.7% x NTI - $79.90 once NTI exceeds $97,600), with bracket adjustments phasing it in between $94,701 and $97,600. Modeled as a recapture of the lower brackets' benefit phased in over $2,900 of NTI (state AGI thresholds assume the $2,470-per-taxpayer standard deduction); the model then taxes all NTI at 3.7%, overstating tax by about $80 above $97,600 of NTI.
• Low-income tax tables (which can reduce tax to zero for low incomes) are not modeled.
• Standard deduction ($2,470 per taxpayer) is the 2025 figure; DFA's 2026 AR1000ES worksheet also uses $2,470. Personal tax credits are $29 per taxpayer ($58 for joint and head of household); dependent, age 65+, blind and deaf credits of $29 each are not modeled.
• Arkansas does not allow the deductible half of self-employment tax.

Arkansas estimated tax payments

Federal estimated payments follow their own schedule. Work them out with the quarterly estimated tax calculator.
