Bright Start 529 tax deduction

Bright Start is Illinois's direct-sold 529 college savings plan. Illinois taxpayers can deduct up to $10,000 a year of contributions ($20,000 married filing jointly) from Illinois income, and at the 4.95% flat rate that's worth up to $495 ($990 joint) a year. The deduction is taken on Schedule M of Form IL-1040, and you should exclude rollovers' earnings and prior-year contributions, as the plan's taxpayer guide explains.

Using the money

Earnings grow tax-free and withdrawals are tax-free for qualified college costs, K-12 tuition (up to the federal annual limit), apprenticeships and some student loan repayment, and up to $35,000 can roll to the beneficiary's Roth IRA after 15 years under federal rules. Nonqualified withdrawals can trigger Illinois recapture of past deductions. Project growth with the 529 calculator.
