Ohio freelance rate & 1099 tax calculator

Ohio income tax for freelancers in 2026

At a glance for 2026: 2 brackets from 0% to 2.75% (single filer), no standard deduction but a $1,900 personal exemption, and quarterly estimated payments are required once you expect to owe tax.

Ohio uses graduated rates up to 2.75%. The calculation starts from your federal adjusted gross income.

How Ohio treats self-employment deductions

• Half of self-employment tax: deductible. Ohio starts from federal AGI, which already reflects the deductible half of SE tax (it reduces nonbusiness income because business income is measured from Schedule C net profit).
• Self-employed health insurance: deductible. Inherited through federal AGI; Ohio's separate unreimbursed health-care deduction must be reduced by the federal SE health insurance deduction to avoid double counting.
• SEP-IRA / solo 401(k) contributions: deductible. SEP/solo 401(k) deductions in federal AGI flow through; no Ohio add-back.

How the calculator handles Ohio

• Ohio business income deduction (modeled): the first $250,000 of business income (Schedule C net profit) is deducted, and business income above $250,000 is taxed at a flat 3%, outside the regular brackets. For most freelancers this means no Ohio income tax on self-employment profit.
• 2026 nonbusiness schedule under R.C. 5747.02(A)(3)(c) as amended by H.B. 96: $0 on Ohio taxable nonbusiness income up to $26,050; above $26,050 the tax is $332 plus 2.75% of the excess (modeled). Business income is handled by the business income deduction above.
• Discrepancy flag: the Ohio Department of Taxation's 2026 IT 1040ES worksheet still prints the 2025-style schedule ($342 + 2.75% to $100,000; 3.125% above). The flat 2.75% for 2026 is taken from the statute/H.B. 96; ODT's final 2026 IT 1040 instructions were not available on 2026-10-22 and should be checked.
• Personal exemption depends on modified AGI (indexing suspended for 2025-2026 by H.B. 96): $2,400 (MAGI <= $40,000), $2,150 ($40,001-$80,000), $1,900 ($80,001 up to the cap), $0 at MAGI of $500,000 or more for 2026. $1,900 per taxpayer/spouse is used here; dependents not modeled.
• Credits not modeled: joint filer credit, $20 exemption credit, nonrefundable credits based on MAGI, retirement/senior credits, earned income credit, credit for taxes paid to other states, and Ohio's own self-employed health insurance/medical deduction rules (Ohio Schedule of Adjustments line 44).

Local income taxes in Ohio

Most Ohio cities and villages levy a municipal income tax (commonly about 1%-2.5%, some higher) on wages and on net profits of self-employed residents and businesses operating there, filed with the city or a collection agency (RITA/CCA). Many school districts also levy a school district income tax (SD 100) on residents: 'traditional base' districts tax Ohio taxable income, 'earned income base' districts tax wages and self-employment income. Rates and coverage vary by address, so neither is modeled.
