Does New Jersey give a tax deduction for 529 contributions?

Yes, starting with the 2022 tax year. New Jersey allows a state income tax deduction of up to $10,000 per year for contributions to the NJBEST 529 plan, but only for taxpayers with gross income of $200,000 or less.

What is the income limit for the New Jersey 529 deduction?

The deduction is available only to households with New Jersey gross income of $200,000 or less. If your gross income exceeds $200,000, you cannot claim the deduction regardless of how much you contribute.

Does the deduction apply to any 529 plan?

No. The New Jersey deduction applies only to contributions to the NJBEST 529 College Savings Plan, the state's own plan. Contributions to out-of-state 529 plans do not qualify for the New Jersey deduction.

Can I carry forward contributions above $10,000?

No. The deduction is capped at $10,000 per year and there is no carryforward of excess contributions in New Jersey. Amounts contributed above $10,000 simply do not generate a state deduction that year.

Are there other New Jersey 529 benefits?

Yes. NJBEST offers a matching grant of up to $750 for new accounts meeting eligibility rules and a tax-free scholarship of up to $3,000 when the beneficiary attends a New Jersey college. Those are separate from the income tax deduction this tool estimates.

New Jersey added a 529 state income tax deduction starting with the 2022 tax year. This calculator estimates the New Jersey income tax you save by contributing to the NJBEST plan, after applying the $10,000 cap and the $200,000 household income limit.

How it works

The deduction is capped and income-limited, so the tool checks eligibility first, then applies your marginal rate:

eligible    = gross income ≤ $200,000
deductible  = eligible ? min(contribution, $10,000) : 0
tax saving  = deductible × marginal NJ tax rate

Only contributions to the NJBEST 529 plan qualify, and there is no carryforward of contributions above the $10,000 cap. If your household gross income is over $200,000, the deduction is unavailable and the saving is zero.

Example and tips

A household earning $150,000 that contributes $10,000 to NJBEST and sits in the 6.37% New Jersey marginal bracket deducts the full $10,000 and saves about $637 in state income tax. A household contributing $4,000 in the same bracket deducts $4,000 and saves about $255. Because the income limit is a hard cliff at $200,000, families near that line should confirm their New Jersey gross income before relying on the deduction. The NJBEST matching grant and in-state scholarship are separate benefits not reflected in this tax-saving figure.
