State estimated tax — 2026

New Jersey Estimated Tax Payments 2026

Who has to make New Jersey quarterly estimated payments, the 2026 due-date calendar, the safe-harbor rules that avoid an underpayment penalty, and how to pay through NJ Division of Taxation Individual Tax Payment Portal.

Who must pay

New Jersey triggers an NJ-1040-ES filing obligation once your projected 2026 tax, net of withholding and credits, tops $400 — but a separate gross-income filing threshold can excuse you entirely: if your total 2026 gross income is at or below $20,000 (married/CU couple filing jointly, head of household, or qualifying widow(er)) or $10,000 (single, married/CU filing separately, or most estates and trusts), you’re not required to file a New Jersey return at all, and owe no estimated tax regardless of the $400 test.

2026 due-date calendar

Installment	% of annual estimate	Due date	Note
Q1	25%	April 15, 2026	—
Q2	25%	June 15, 2026	—
Q3	25%	September 15, 2026	—
Q4	25%	January 15, 2027	—

New Jersey divides the required payment into four equal installments; taxpayers who first become liable later in the year catch up with a larger first payment (1/3 if starting at the June voucher, 1/2 at September, or the full amount at January). Farmers whose farming income (including oyster farming) is at least two-thirds of total estimated income can skip the quarterly schedule and submit one lump-sum payment any time on or before January 15, 2027.

Safe harbor — avoiding the underpayment penalty

New Jersey’s Form NJ-2210 penalty steps aside once your payments reach whichever is smaller — 80% of your actual 2026 tax liability, or 100% of your 2025 tax liability (only available when that prior return spans a full year). New Jersey shares Massachusetts’s lower 80% current-year bar rather than the 90% most states use, and adds nothing extra for high earners: there’s no equivalent here to California, New York or Michigan’s 110% rule triggered above a set AGI line.

How to calculate your payment

Estimate your annual New Jersey tax, test it against the safe harbor above, then split the required annual payment across the installments in the calendar. The site's quarterly planner handles the math and the federal side together.

Penalty basics

New Jersey charges interest on outstanding tax balances at the average predominant prime rate plus 3 percentage points, compounded annually, redetermined each December for the following calendar year — 10.00% for calendar year 2026 (Technical Bulletin TB-21(R)).

New Jersey-specific notes

New Jersey’s estimated-tax requirement has two independent gates: the usual $400 tax-owed trigger, AND a gross-income filing threshold ($10,000 single/MFS, $20,000 MFJ/HOH/QW) below which you don’t have to file a return — or make estimated payments — at all, even if tax liability would otherwise exceed $400.
New Jersey’s 80% current-year bar undercuts the federal government’s usual 90% test — a trait it shares with Massachusetts, not with California, New York or Michigan’s stricter 90% baseline.
New Jersey has no high-income safe-harbor step-up despite its steep 10.75% top rate on taxable income over $1,000,000 — the flat 80%/100% test applies at every income level.
Nonresident sellers of New Jersey real estate face a completely SEPARATE estimated Gross Income Tax payment collected at closing (Form GIT/REP-1) — a distinct, one-time transaction-based system, not part of the quarterly NJ-1040-ES cycle this page covers.

See the New Jersey 2026 tax brackets for current rates, or the New Jersey state tax calculator to estimate your full-year liability.

Frequently asked questions

When are New Jersey estimated tax payments due in 2026?

The four New Jersey due dates for 2026 are April 15, 2026, June 15, 2026, September 15, 2026, January 15, 2027. New Jersey divides the required payment into four equal installments; taxpayers who first become liable later in the year catch up with a larger first payment (1/3 if starting at the June voucher, 1/2 at September, or the full amount at January). Farmers whose farming income (including oyster farming) is at least two-thirds of total estimated income can skip the quarterly schedule and submit one lump-sum payment any time on or before January 15, 2027.

If my income is under New Jersey’s filing threshold, do I still need to make estimated payments?

No. If your total 2026 gross income is at or below $20,000 (married/CU couple filing jointly, head of household, or qualifying widow(er)) or $10,000 (single, married/CU filing separately), you’re not required to file a New Jersey return at all — and with no filing requirement, there’s no estimated-tax obligation either, regardless of the usual $400 tax-owed trigger.

Does New Jersey step up its safe harbor for high-income filers, the way California or New York do?

No. Form NJ-2210 keeps the same 80/100 comparison for every filer, with nothing resembling the 110% high-income tier some other states use — a bit surprising given New Jersey’s 10.75% top rate, among the highest in the country.

I sold New Jersey real estate as a nonresident — is that covered by my regular NJ-1040-ES estimate?

No, it’s a separate system. Nonresident sellers of New Jersey real property make an estimated Gross Income Tax payment at closing using Form GIT/REP-1, collected through the county clerk — distinct from, and not a replacement for, the quarterly NJ-1040-ES estimated payments covered on this page.
