Does Texas offer a 529 plan tax deduction?

No. Texas has no state income tax, so there is no state income tax deduction or credit for 529 plan contributions. There is simply no state tax to deduct against, unlike states such as New York that offer a deduction.

Why Texas 529 savers focus on federal benefits

Many states reward 529 contributions with a state income tax deduction or credit. Texas does not — and the reason is simple: Texas has no state income tax at all, so there is nothing to deduct against. That doesn’t make a Texas 529 plan worthless, though. The real prize is federal: your investments grow tax-deferred, and withdrawals for qualified education expenses come out completely free of federal tax on the earnings.

This tool confirms the $0 state deduction and then projects how much your account grows and how much federal tax that tax-free growth saves you.

How it works

The projection uses standard compound-growth math:

  1. The initial lump sum grows monthly: FV = principal × (1 + r/12)^months.
  2. Monthly contributions grow as an annuity: FV = payment × ((1 + r/12)^months − 1) / (r/12).
  3. Earnings are the projected value minus everything you contributed.
  4. The estimated federal tax saved is your earnings × the tax rate you’d otherwise pay on investment gains — savings you keep because qualified 529 withdrawals are federally tax-free.

Tips and notes

  • Because Texas gives no state deduction, you are free to pick any state’s 529 plan — shop for the lowest fees nationwide.
  • The “tax rate on gains” field should reflect what you’d otherwise pay on long-term capital gains or dividends (commonly 0%, 15%, or 20% federally).
  • Returns are assumptions, not guarantees, and withdrawals must be for qualified education expenses to stay tax-free. This is an estimate, not investment or tax advice.
