- Look up your state's 529 deduction rules45 min
This step produces the one-page sheet every later decision leans on: your state's deduction cap, its limits, and the tax year the rules apply to. It is tricky because states write these rules differently — the cap may run per beneficiary or per account, some states phase the deduction out by income, a few restrict the beneficiary's age, and rollover contributions often do not count like new ones.
- Open your state's revenue or treasury site — search “[your state] 529 tax deduction” and take the .gov result over third-party summaries.
- Open the 529 or qualified tuition program (QTP) page, not the plan's marketing page.
- Write down each field: the maximum deductible contribution per year and whether it is per beneficiary or per account; any income phase-out; any beneficiary age limit; whether the deduction covers contributions only or also rollovers into the plan.
- Note the deadline the state sets — most states require the contribution to post by December 31 of the tax year you claim it on.
- Record the page URL and the tax year (for example, 2026) at the top of the sheet, so the source stays checkable.
