Local income tax (never in the total above): Most Ohio cities levy a municipal income tax of 1% to 3% on net profits (Columbus and Cleveland: 2.5%), and many school districts levy their own. The business income deduction does not apply to city tax. Neither is included here.
Amounts to set aside, not bills: federal $3,701 for each Form 1040-ES installment (Apr 15, Jun 15, Sep 15, Jan 15). Ohio: $0 per installment on its own schedule. For the safe-harbor amount and payments you have already made, use the quarterly calculator with these inputs.
Ohio and self-employment income
Ohio is unusually favorable to sole proprietors: the Business Income Deduction excludes the first $250,000 of business income entirely, and any excess is taxed at a flat 3%. Only non-business income (such as W-2 wages) goes through the regular schedule — 0% up to $26,050 and a single 2.75% rate above it from 2026 (2025 still had a 3.125% band over $100,000). From 2026 the personal and dependent exemptions disappear once income reaches $500,000.
Ohio rules used by this calculator (2026)
- Ohio applies a flat 2.75% rate on income above $26,050 for 2026.
- There is no standard deduction.
- Each filer gets a personal exemption that depends on income.
- The per-dependent deduction steps down as income rises.
- Ohio's earned income credit is 30% of the federal credit, nonrefundable; the calculator applies it.
- A credit of $20 per person on the return at low incomes (up to $30,000 single / $30,000 joint); the calculator applies it.
- Business income up to $250,000 is deducted; business income above that is taxed at a flat 3%, and only non-business income goes through the brackets.
- The schedule has fixed steps written into the statute: $332.00 once non-business taxable income exceeds $26,050.
- Ohio starts from federal AGI, so the deductible half of self-employment tax reduces state income as well.
- Most Ohio cities levy a municipal income tax of 1% to 3% on net profits (Columbus and Cleveland: 2.5%), and many school districts levy their own. The business income deduction does not apply to city tax. Neither is included here.
What an Ohio freelancer may still owe
- Ohio requires estimated payments (Form IT 1040ES) when you expect to owe more than $500.
- Most Ohio cities levy a municipal income tax of 1% to 3% on net profits, and the Business Income Deduction does not apply to city tax — for many Ohio freelancers the city bill is larger than the state bill.
- Applied here: the $20 credit per exemption for incomes under $30,000 and Ohio's earned income credit (30% of the federal credit, against the tax). Ohio has no child tax credit; the joint filing credit is not included.
- For 2026 the statute and the Department's own worksheet disagree, and the figures here follow the statute. R.C. 5747.02(A)(3)(c) sets a single bracket — $332.00 plus 2.75% above $26,050 — while the 2026 Ohio Estimated Income Tax Instructions (last updated 4 May 2026) still print the 2025 table, which adds a 3.125% band over $100,000. On $200,000 of non-business income that worksheet produces $403.69 more than the statute, and on $500,000, $1,528.69 more. Expect the estimated-payment voucher to ask for the higher amount until the Department updates it.
What Ohio costs at three levels of profit (2026)
A single filer with no dependents and no other income, taking the standard deduction. The state column is Ohio's own tax after its deductions, exemptions and credits.
| Net profit | Federal | Ohio | Total | Effective rate |
|---|---|---|---|---|
| $50,000 | $9,732 | $0 | $9,732 | 19.46% |
| $75,000 | $15,495 | $0 | $15,495 | 20.66% |
| $100,000 | $22,365 | $0 | $22,365 | 22.36% |
Ohio takes nothing at any of these levels: its deductions, exemptions and credits cover the whole of a sole proprietor's profit. Change any input in the calculator above to see your own figures.
How the federal part is worked out
Net profit is 1099 income less business expenses (Schedule C). Self-employment tax is 15.3% of 92.35% of that profit — 12.4% Social Security up to $184,500 of combined wages and earnings, 2.9% Medicare on all of it. Half of that tax, the $16,100 standard deduction ($32,200 joint) and the 20% qualified business income deduction come off before the 2026 brackets are applied; the child tax credit and the earned income credit then reduce what is left, and the refundable parts can offset self-employment tax. The methodology page sets out the full sequence and every rule the calculator leaves out, including how Ohio's figures are derived.
Quarterly estimated tax deadlines (2026)
If you expect to owe $1,000 or more of federal tax for the year, the IRS expects four estimated payments (Form 1040-ES). Ohio runs its own estimated-payment schedule with its own threshold (see above); the calculator shows the federal installment and the Ohio installment separately, and one combined amount to set aside each quarter.
The 2026 dates are April 15, 2026, June 15, 2026, September 15, 2026, January 15, 2027. The federal amount is split into four equal Form 1040-ES installments after any withholding you entered; paying 100% of last year's tax instead (110% above $150,000 of prior-year AGI) also avoids the penalty. The quarterly calculator works that out and subtracts what you have already paid, and the guide to the due dates explains the rule.
Common questions
Does Ohio tax self-employment income differently from wages?
For state income tax, net profit from self-employment is ordinary income like wages. The self-employment tax itself is federal only; Ohio does not add a state equivalent.
Is half of self-employment tax really deductible?
Yes, for federal tax. The employer-equivalent half is an adjustment to income on Schedule 1, which lowers your AGI and therefore your federal income tax. It does not reduce the self-employment tax itself.
Does an LLC change these numbers?
For federal income tax and self-employment tax, a single-member LLC taxed as a sole proprietorship follows exactly the calculation shown here. State and local obligations can still differ: an LLC may be a taxable entity for a state's franchise, gross-receipts or excise tax, and may owe registration or licence fees a sole proprietor does not — Ohio's are listed above. Electing S-corporation status changes the federal arithmetic too (salary plus distributions) and is outside this tool's scope.
What if I moved to Ohio during the year?
Income earned while you were a resident of another state is taxable there under that state's rules. This calculator assumes all income was earned as an Ohio resident.
