Ohio529 tax deduction

Ohio taxpayers can deduct contributions to Ohio's 529 plan (CollegeAdvantage) of up to $4,000 per beneficiary per year from Ohio taxable income, with unlimited carryforward of anything above $4,000. The deduction is for Ohio's own plan, so check before contributing to another state's plan. At Ohio's 2.75% rate, $4,000 saves $110.

Example: $6,000 for one child: $4,000 deducted now, $2,000 next year. Project growth with the 529 calculator.
