What are 'Tax Parity' states?

Some states (like PA or AZ) allow you to deduct contributions to ANY state's 529 plan, not just their own.

What if the beneficiary doesn't go to college?

You can change the beneficiary to another family member, or use the new 529-to-Roth IRA rollover provision.

What is a 529 Plan?

A 529 plan is a tax-advantaged savings plan designed to encourage saving for future education costs. Named after Section 529 of the Internal Revenue Code, these plans are sponsored by states, state agencies, or educational institutions.

While there is no federal tax deduction for contributions, over 30 states offer some form of tax deduction or credit for your contributions.

How to Use This Calculator

Select Your State - Choose the state where you file your income tax returns.
Enter Contribution - Input the total amount you plan to deposit into the 529 account this year.
Estimate Tax Rate - Use your state's marginal tax rate (typically 3% to 9%).

Calculation Formula & Example

The Formula

Savings = Min(Contribution, State Limit) × State Tax Rate

Where:

State Limit = The maximum amount your state allows you to deduct (varies by state).
Tax Rate = Your specific state income tax bracket.

Example Calculation

In New York, you can deduct up to $5,000 for single filers. If you contribute $5,000 and your NYS tax rate is 6%, you save $300 on your state tax bill.
