Ohio 529 tax questions

Does Ohio have a 529 tax deduction?

Yes. Ohio lets you deduct up to $4,000 per beneficiary of contributions to any state's 529 plan.

Which 529 plans qualify for Ohio's deduction?

Any state's 529 plan. Ohio allows the deduction for contributions to any 529 plan, not only its own.

Yes. Any excess carries forward to later years with no time limit, still limited each year per beneficiary. Any contributor can claim the deduction, not only the account owner.

What the calculator leaves out

The calculator assumes the contribution goes to a plan that qualifies for the state's benefit: the state's own plan unless the state accepts any 529 plan. Wages are the only income, and they stand in for the income a state tests against its limits. Per-beneficiary limits assume the contribution is split evenly. Federal tax does not change, because 529 contributions aren't federally deductible. Carryforwards of earlier contributions, recapture on nonqualified withdrawals and city or school district taxes are left out.
