New Jersey 529 tax deduction in 2026

New Jersey taxpayers whose gross income is $200,000 or less can deduct up to $10,000 of the money they put into an NJBEST account during the year, the Franklin Templeton 529 plan offered by the state's Higher Education Student Assistance Authority. The figure does not double on a joint return: a married couple has the same $10,000 as a single filer, and spouses filing separately share it. A couple at $142,000 of taxable income who reach the cap saves $553; a single parent at $57,000 putting in $1,800 saves $99. Above the income line the deduction is zero, not reduced. Contributions to another state's plan earn nothing. New Jersey follows federal law on K-12 tuition, so a private school withdrawal is not taxed by the state, while its treatment of Roth IRA rollovers and student loan payments is not confirmed on an official page, and the rollover of an NJBEST account to another state is not addressed in the texts read.

The $200,000 line works like a switch
The College Affordability Act gave New Jersey its first 529 deduction for tax years 2022 and later. The test is gross income, and it is the same $200,000 for every filing status. A couple slightly above it, say $204,000, gets $0 for a full $10,000 deposit. At $196,000, the same deposit would have saved $637. There is no phase-out to soften the step.
Our calculator compares the household taxable income you type with the limit, which is a simplification: gross income is usually higher than taxable income, so a family whose taxable figure sits close to $200,000 should check line by line on the NJ-1040 before counting on the deduction.

Single or married, the same $10,000
Most states that cap a 529 deduction give a joint return twice the single amount. New Jersey does not print a joint figure; its instructions only say that spouses filing separately cannot together exceed the stated amount, which is how we read the cap as one per return. Children do not raise it either: a couple who puts $10,000 into each of two NJBEST accounts deducts $10,000 in total and saves $553, the same as with one account.
The value climbs with the bracket. New Jersey's graduated schedule runs from 1.4 % up to 10.75 %, but anyone near the top rate has income well past the $200,000 test, so the families who can claim it mostly deduct in the middle of the schedule: both the nurse and the couple above sit at 5.525 %.
NJBEST only
The Division of Taxation page on the College Affordability Act limits the deduction to contributions to an NJBEST account. A deposit of $6,000 in another state's plan saves $0 on the New Jersey return. Federal treatment of that account is unchanged; only the state subtraction is lost.
Private school tuition and the open questions
New Jersey's Division of Taxation updated its notice in May 2025 to say the state follows the federal rule on elementary and secondary tuition, including religious schools. A withdrawal within the federal cap of $20,000 per child from 2026 is therefore free of Gross Income Tax. How New Jersey handles the other K-12 costs added by the 2025 federal law, credential programs, Roth IRA rollovers and student loan payments is not stated in the official texts we read; a 2026 bill would make Roth rollovers from NJBEST qualified, which suggests the point is open.

| New Jersey treatment | Treated as qualified |
On a non-qualified withdrawal, the NJ-1040 instructions tax the earnings and the part of the contributions deducted earlier. The add-back page shows how that works across states. No balance limit for NJBEST appears on an official page we could read.
