Saving for college? Most parents skip a free $200-$1,500 state tax deduction every year.

A 529 plan is a state-sponsored savings account specifically for education. You put money in (after federal tax — there's NO federal deduction), it grows tax-free, and when you pull it out for qualified education expenses (tuition, room/board, books, even K-12 private school up to $10k/year), you pay ZERO tax on the growth. So if you put in $50,000 and it grows to $150,000 over 18 years, you keep all $100,000 of growth tax-free. It's basically a Roth IRA for education. The bonus: many states give you a STATE-level tax deduction or credit for contributing to their plan — a $200-$1,500/year benefit on top of the tax-free growth.

Meet the Patels. Two kids (ages 3 and 5), live in Illinois (one of the most generous 529 states), filing married. They contribute $20,000/year to Illinois's BrightStart 529. RIGHT NOW: they get a $20,000 deduction on their Illinois state return. At Illinois's 4.95% flat rate, that saves them $990/year in state tax. OVER 13 YEARS until the older kid hits college: contributing $20k/year at 6% growth = ~$400,000. About $140,000 of that is growth — completely tax-free when used for tuition. Compared to investing in a regular taxable brokerage where they'd pay 15% LTCG on the growth: they save another ~$21,000 in federal capital gains tax. Total benefit over 13 years: ~$13,000 in state tax savings + $21,000 in federal tax savings = $34,000 they would NOT have saved by investing in a regular account.

Depends on the state. (1) NO STATE DEDUCTION (7 states): California, Delaware, Hawaii, Kentucky, Maine, North Carolina, New Jersey. If you live in these states, the only benefit is federal tax-free growth — still worth it, but no extra state goodies. (2) UNLIMITED DEDUCTION (5 states): Colorado, New Mexico, South Carolina, West Virginia, Pennsylvania (sort of). You can deduct as much as you put in. (3) MOST STATES: cap between $1,000 and $20,000/year. New York and Illinois give the highest at $5k single / $10k married (NY) and $10k single / $20k married (IL). (4) Eight states (AZ, AR, KS, MN, MO, MT, OH, PA) let you deduct contributions to ANY state's 529 — so you can use whichever plan has the best investment options. The other 35+ states require you use THEIR plan to get the deduction.

Three options: (1) Change the beneficiary to another family member — sibling, cousin, even yourself if you go back to school. The IRS defines 'family member' broadly. (2) Roll up to $35,000 lifetime into a Roth IRA for the beneficiary (rule started in 2024 — has to be a 529 that's been open 15+ years). This basically turns 'unused' 529 money into retirement savings for your child. (3) Take a non-qualified withdrawal — you owe income tax on the GROWTH portion (not your original contributions) plus a 10% penalty on the growth. Annoying but not catastrophic if your alternative was zero. Most families don't actually face the 'unused 529' problem because qualified expenses now include K-12 tuition (up to $10k/yr), trade schools, and apprenticeships.

If your state offers ANY tax benefit, use the home state plan — the tax savings almost always outweigh slightly higher fees. Example: even Vermont's small 10% credit (capped at $250/yr) typically beats the savings from picking a 0.05%-cheaper out-of-state plan. The exceptions: (a) you live in a state with NO state deduction (CA, DE, HI, KY, ME, NC, NJ) — then shop around freely. The best out-of-state plans by fees: Utah (my529), Nevada (Vanguard 529), New York (Direct Plan). All have rock-bottom expense ratios under 0.10%. (b) You live in a state that allows ANY 529 (AZ, AR, KS, MN, MO, MT, OH, PA) — you get the deduction PLUS your pick of plan. (c) Your home state's plan has terrible fees (>0.50% expense ratio) and your state's deduction is small (<$1k savings/yr). Then the math sometimes flips.

Yes, sometimes better. The 529 owner gets the state tax deduction, NOT the parent of the beneficiary. So if grandparents contribute $10,000/year to a 529 for their grandchild, the GRANDPARENTS get the state deduction (assuming they're in a state with one). One quirk: the FAFSA financial-aid formula treats parent-owned 529s differently from grandparent-owned 529s. Parent-owned: counted as parent asset (5.6% impact on aid). Grandparent-owned: was historically counted as student income (50% impact!) — but the 2024 FAFSA Simplification Act eliminated this. Now grandparent 529s have ZERO FAFSA impact. So in the post-2024 world, grandparents contributing to their own 529 (instead of giving cash to parents to contribute) is the optimal play.

Generous list: tuition (K-12 private up to $10k/yr; college; grad school; trade schools), required fees, room and board (if enrolled at least half-time — caps at the school's published cost of attendance), books and supplies, computers and internet (yes, really), special needs equipment. Student loan repayment up to $10,000 lifetime per borrower (added in 2019 SECURE Act). Apprenticeships registered with the Department of Labor. NOT qualified: transportation, health insurance, club fees, sports gear (unless required by the program). If you withdraw for non-qualified expenses, you pay tax + 10% penalty on the GROWTH portion only.
