Ohio does tax income from self-employment but allows taxpayers to deduct the first $250,000 of business income included on a US federal income tax return earned by taxpayers filing 'Single' or 'Married filing jointly'; taxpayers who file 'Married filing separately' may deduct the first $125,000.
The point by awesome jwilliams50 is that the deduction will probably wipe out all your DoorDash income, making none of it taxable to Ohio.
