    The eight full tax-parity states

    Arizona, Kansas, Maine, Minnesota, Missouri, Montana, Ohio, Pennsylvania.

    Arkansas also accepts another state's plan, at a lower $3,000 cap (vs $5,000 for its own plan), so it is not counted as full parity. Georgia is separate: its 2026–2030 rule covers qualifying reciprocal plans, within a combined cap, so Georgia is not counted as full parity.

    How negative claims are labeled

    9 jurisdictions are structural negatives because they have no broad-based individual income tax. The remaining no-benefit states—California, Hawaii, Kentucky, North Carolina—are enumeration-backed negatives: no contribution benefit for them appeared in the positive-state enumeration. They are not disguised as individually sourced affirmative findings.

    Frequently asked questions

    Does every state give a tax deduction for 529 contributions?

    No. 38 jurisdictions publish a deduction or credit in this 2026 registry. Nine jurisdictions have no broad-based individual income tax, and 4 income-tax states are recorded as no-benefit because they did not appear in the positive-state enumeration.

    Can I deduct a contribution to another state's 529 plan?

    Arizona, Arkansas, Kansas, Maine, Minnesota, Missouri, Montana, Ohio, Pennsylvania publish a benefit that can apply to another state's plan. Arkansas uses a smaller cap for another state's plan. Georgia has a narrower reciprocal-plan rule for 2026 through 2030 and is not counted as full tax parity.

    Are all 529 contribution deadlines December 31?

    No. Several states permit a contribution made by a return-related deadline to be elected for the preceding tax year. When an official source did not state a deadline, this guide says not asserted instead of assuming December 31.

    Can a nonqualified withdrawal reverse a state 529 tax benefit?

    Sometimes. State addback, recapture, rollover, and penalty rules differ. This registry displays a recapture rule only where the cited official excerpt supports it; otherwise the field is deliberately not asserted.
