Washington, DC 529 Tax Deduction 2026: up to $8,000 a year, worth about $520
Washington, DC takes money off your state tax bill when you put money into a 529 college fund for your child. Most parents never claim it — not because it's hard, but because nobody told them. Here's the whole thing in plain English.
What you can deduct
$4,000 ($8,000 married filing jointly) per year, per taxpayer. Fine print: per taxpayer.
What it's worth
About 6.5 cents per dollar you contribute, up to the limit.
| You put in | Off your Washington, DC tax bill (≈) |
|---|---|
| $1,000 | $65 |
| $2,500 | $162 |
| $4,000 | $260 |

The trick: you don't need new money
If you pay for daycare, you probably qualify for federal tax breaks worth $1,000–$3,000 a year — the Dependent Care FSA at work and the childcare credit at tax time. Route that money into the 529 and Washington, DC pays you again for saving it. Same dollars, three tax breaks.
See all three breaks on your numbers — free 3-minute check. No card, no SSN, no bank login needed.
