Can I get a state tax deduction for contributing to a 529 plan?

In many states, yes, even though 529 contributions never reduce your federal taxable income. More than 30 states offer a state income tax deduction or credit for 529 contributions, often capped (commonly $5,000–$10,000 per year, with limits varying by filing status). Some states only give the break for contributing to their own plan; a handful are "tax parity" states that reward contributions to any state's plan. A few states with no income tax (and a couple of others) offer no deduction at all. To capture the benefit, you generally have to contribute before December 31. Withdrawals used for qualified education expenses are tax-free at both levels. Check your specific state's rules, then map college costs with wealthserene.com/tools/college-planner.
