New Jersey estimated tax payments for 2026 are due April 15, June 15, September 15, 2026, and January 15, 2027, paid online or with Form NJ-1040-ES, and they are required when you expect to owe more than $400 of New Jersey income tax after withholding and credits. Only the January 15, 2027 installment is still ahead. New Jersey charges underpayment interest only when your timely payments fall short of the lesser of 80% of your 2026 tax or 100% of your 2025 tax, a lower bar than the 90% the IRS asks for, with no 110% tier for high earners. A shortfall costs interest at 10% a year for 2026, charged for every month or part of a month.
Key takeaways:
2026 due dates: April 15, June 15, September 15, and January 15, 2027; filing the 2026 return and paying in full by February 15, 2027 replaces the January installment
The trigger is more than $400 of New Jersey tax after withholding and credits, for residents and nonresidents alike
Safe harbor: the lesser of 80% of 2026 tax or 100% of 2025 tax. New Jersey has no 110% rule
Rates run from 1.4% to 10.75%; New Jersey has no standard deduction, only $1,000 personal exemptions, and no deduction for half of self-employment tax
Interest is 10% a year for 2026 (prime 7.00% + 3%), counted by the month, and none at all if you had no 2025 New Jersey tax
New Jersey uses the federal calendar, per the 2026 NJ-1040-ES instructions. If your income changes mid-year and first creates a payment requirement, you spread the year's estimate over the dates that remain:
Installment
Due date
If a change first requires estimates
1
April 15, 2026 (passed)
Pay the full year now, or one-fourth
2
June 15, 2026 (passed)
Change after April 1 and before June 2: one-third now and on each later date
3
September 15, 2026 (passed)
Change after June 1 and before September 2: half now, half in January
4
January 15, 2027 (a Friday)
Change after September 1: the full amount
A due date that falls on a weekend or legal holiday moves to the next business day. The calendar matches federal Form 1040-ES, so the federal and New Jersey January payments land on the same Friday.
The right-hand column covers new obligations only. If you owed estimates all year and simply skipped them, GIT-8 says the first payment you make must include every past-due installment, and the rest stay on schedule. Someone who owed $250 a quarter and paid nothing until September owes $750 on September 15 and $250 in January.
New Jersey also lets you skip the January voucher: file your 2026 return and pay the entire balance by February 15, 2027. That date is Presidents' Day, and GIT-8 rolled the same deadline for 2025 returns to February 17, 2026 because of a weekend and the holiday, so expect Tuesday, February 16, 2027; filing by Friday, February 12 removes the question. Selling taxable goods is a separate calendar: New Jersey sales tax due dates run on their own quarterly schedule.
You must make New Jersey estimated payments if you expect to owe more than $400 of New Jersey Gross Income Tax after subtracting withholding and other credits, whether you are a resident or a nonresident, per the Division of Taxation's estimated payments page. Freelance and Schedule C profit, partnership and S corporation income, rental income, interest, dividends, capital gains, and retirement distributions without withholding are the usual sources.
Three groups are out. If your gross income for the whole year is at or below the filing threshold ($10,000 for single filers and married filing separately; $20,000 for joint filers, heads of household, and surviving spouses), you file no return and make no estimates. If you paid estimates for 2025 but expect no 2026 liability, the NJ-1040-ES instructions say you can stop. And a wage earner can skip vouchers entirely by giving the employer a new Form NJ-W4 with extra withholding (retirees use NJ-W-4P with the pension payer).
Commuters run the math differently. A New Jersey resident who works in Manhattan pays New York nonresident tax and takes a credit for income taxes paid to other jurisdictions on line 17 of the NJ-1040-ES worksheet, so the New Jersey estimate covers only the difference; the New York side runs on its own vouchers, explained in our New York estimated tax guide. Nonresidents selling New Jersey real property may also owe an estimated payment at closing.
New Jersey charges interest on an installment only when your withholding and timely estimates fall short of the lesser of 80% of the 2026 tax or 100% of the 2025 tax, under N.J.S.A. 54A:9-6(c) and the 2025 Form NJ-2210. Form NJ-2210 then gives four more ways to clear a quarter that still looks short:
Test
Cumulative amount required by each due date
Condition
Current year (Part I)
20%, 40%, 60%, 80% of 2026 tax
Measured against the actual tax on your 2026 return
Exception 1: prior year
25%, 50%, 75%, 100% of 2025 tax
2025 return covered 12 months and showed a tax
Exception 2
Same percentages of the tax on 2025 income at 2026 rates and exemptions
Helps when you gained exemptions, such as a new dependent
Exception 3: annualized income
20%, 40%, 60% of tax on annualized income (first three quarters)
Income that arrived late in the year
Exception 4: actual income
90% of tax on actual income through March, May, and August
Same idea, without annualizing
New Jersey never raises the prior-year anchor to 110%, and its current-year test is 80% where the IRS asks for 90% under IRC §6654(d). An estimate can miss by a fifth before interest starts.
Bettina, a freelance brand designer in Hoboken, expects $4,243.75 of 2026 New Jersey tax (the worksheet is in the next section). Her 2025 New Jersey tax was $3,200. Her safe harbor is the lesser of 80% × $4,243.75 = $3,395 or 100% × $3,200 = $3,200, which is $800 per installment. She pays $800 on each date and settles the remaining $1,043.75 with her 2026 NJ-1040 by April 15, 2027, with no interest, because the prior-year anchor holds no matter how high 2026 runs. Under the IRS-style 90% test her current-year option would be $3,819.38; New Jersey's 80% puts it at $3,395.

2026 NJ-1040-ES rate tables (1.4% to 10.75%) and 2025 Form NJ-2210. Safe harbor: the lesser of 80% of 2026 tax or 100% of 2025 tax; New Jersey has no 110% tier. Withholding and credits such as the BAIT credit count as paid evenly through the year. No estimates are required when tax after withholding and credits is $400 or less. Underpayments cost interest at 10% a year for 2026 (TB-21), charged for each month or part of a month.
Paying it all in January. Form NJ-2210 tests each quarter in its own column; one large January payment leaves April, June, and September short
A 2025 return that covered less than 12 months. Exception 1 is unavailable, so the 80% test or Exceptions 2 through 4 have to carry every quarter
Money sent to the wrong account. The Division's BAIT page says an entity's BAIT estimates cannot be applied to any other tax account, so they never count as your NJ-1040-ES payment; only the credit on your return does
New Jersey does not start from federal adjusted gross income. The NJ-1040-ES worksheet builds New Jersey gross income from its own categories, subtracts exemptions and a short list of deductions, and applies one of two rate tables:
Worksheet line
What goes there
1–3
Total income expected, minus the pension and retirement exclusion, equals New Jersey gross income
4a–4c
Exemptions: $1,000 each for you and your spouse, plus $1,000 for age 65+ and for blindness or disability; $1,500 per dependent; $6,000 per honorably discharged veteran
5–11
Deductions: medical costs above 2% of gross income, self-employed health insurance, alimony, and a few narrower items
13–15
Taxable income, minus the property tax deduction
16
Tax from Table A or Table B
17–18
Minus the credit for income taxes paid to other jurisdictions
19–21
Minus New Jersey withholding and other credits, including the BAIT credit

The worksheet turns each bracket into one step: multiply taxable income by the rate for your bracket, then subtract the table's fixed amount, such as $2,126.25 for a single filer in the 6.37% bracket.
Three New Jersey rules move a freelancer's number away from the federal one. The worksheet has no line for the deductible half of self-employment tax, no standard deduction, and no qualified business income deduction. Business profit comes from Schedule NJ-BUS-1, which starts with federal Schedule C, adds back taxes based on income, lets you deduct qualified contributions to a self-employed 401(k), and adjusts federal bonus depreciation and section 179 through worksheet GIT-DEP, per the 2025 NJ-1040 instructions. Losses do not cross categories either: a net business loss goes on the return as zero, so it cannot shelter W-2 wages directly; Schedule NJ-BUS-2 (the alternative business calculation adjustment on worksheet line 9) recovers part of such losses and carries unused amounts forward for up to 20 years. Building Jupid, I keep running into New Jersey freelancers who copied federal AGI into the state worksheet; the two numbers rarely match.
Worked example. Bettina (single, no dependents, no New Jersey withholding) expects $108,000 of 2026 Schedule C profit with no New Jersey adjustments and $2,000 of bank interest, and she pays $9,000 a year for her own health insurance.
Step

Schedule NJ-BUS-1 profit

Line 3: New Jersey gross income

Line 4a: one $1,000 exemption
−$1,000
Line 5: self-employed health insurance
−$9,000
Line 15: New Jersey taxable income (no property tax deduction)
$100,000
Line 16: Table A, $100,000 × 6.37% − $2,126.25
$4,243.75
Her federal AGI subtracts about $7,630 for half of self-employment tax; at 6.37%, carrying that deduction into the New Jersey worksheet by mistake would understate her state estimate by $486. Her federal vouchers cover income tax plus 15.3% self-employment tax separately.
The Division of Taxation's Pay Tax page links to the individual payment system ("Option A"), which takes estimated payments two ways:
E-check, withdrawn directly from your bank account. You need the Social Security number and date of birth of the first person listed on your New Jersey return, and payments can be scheduled in advance
Credit card (American Express, Discover, MasterCard, or Visa) online or by phone at 1-888-673-7694, with a processing fee added to the payment
Do not mail a voucher when you pay electronically. To pay by mail, complete the 2026 NJ-1040-ES voucher for the installment and send it with a check or money order payable to State of New Jersey – TGI, with your Social Security number written on it, to State of New Jersey, Division of Taxation, Revenue Processing Center, PO Box 222, Trenton, NJ 08646-0222. On a joint return, list both Social Security numbers in the order your names appear on the return. A 2025 overpayment you applied to 2026 is credited to the first installment automatically, and the voucher can never pay a prior-year balance; that needs a payment plan or a regular balance-due payment.
New Jersey charges interest on underpaid estimates and no separate penalty. Technical Bulletin TB-21(R) sets the 2026 rate at 10.00%: the 7.00% prime rate in effect on December 1, 2025, plus 3%, compounded annually. The NJ-2210 instructions charge it for each month or fraction of a month an underpayment exists, through April 15, 2027 at the latest, and the Division reviews the rate quarterly but changes it only after a cumulative prime-rate move of more than one point.
Counting by the month makes a one-day slip expensive relative to its size. Suppose Bettina skips her $800 September 15 installment:
Catch-up date
Months charged
Interest at 10%
October 15, 2026
1
$6.67
December 15, 2026
3
$20.00
December 16, 2026
4
$26.67
April 15, 2027, with the return
7
$46.67, if the rate stays at 10%
The federal version, described in our estimated tax penalty guide, accrues daily at a rate that resets each quarter; New Jersey's month-or-fraction rule rewards paying before the 15th of the next month.
You can compute the interest on Form NJ-2210 and report it on the NJ-1040 (line 52 on the 2025 return), or leave it to the Division, which, per GIT-8, will calculate it and send a bill. If Exception 1 covers all four quarters, do not file the form at all. Interest does not apply if you had no tax obligation on your 2025 return. Tax left unpaid after April 15, 2027 is a different problem: the penalties and interest page adds a 5% late payment penalty on top of interest.
The Pass-Through Business Alternative Income Tax (BAIT) lets an eligible partnership, New Jersey S corporation, or LLC taxed as either pay New Jersey tax at the entity level, per the Division's BAIT page. Single-member LLCs and sole proprietorships cannot elect. The entity pays 5.675% on the first $250,000 of distributive proceeds, 6.52% on $250,001 to $1,000,000, and 10.9% above $1,000,000.
The election for 2026 can be filed as late as March 15, 2027, but the entity cannot make any payment, estimates included, before it elects. An electing entity whose BAIT liability will exceed $400 pays its own estimates on Form PTE-150 on the same four dates. Members then claim a refundable credit on the NJ-1040, and Form NJ-2210 counts that credit as paid evenly through the year, the same way it treats withholding. An owner whose entity elected and paid on schedule may need little or nothing on the personal NJ-1040-ES; income the BAIT does not cover still needs personal estimates. The federal reason entities elect is covered in our SALT deduction guide.
New Jersey estimated payments are deductible as state income taxes on federal Schedule A in the year you pay them, per Treasury Regulation §1.164-1, so Bettina's January 15, 2027 installment is a 2027 federal deduction. Itemizers with room under the SALT cap in IRC §164 can pay it in December to pull the deduction into 2026; an early payment still counts for the January installment.
Federal AGI already subtracts half of self-employment tax, and New Jersey does not allow it. On $108,000 of profit that is a $486 understatement before anything else goes wrong.
A net loss on Schedule NJ-BUS-1 goes on the NJ-1040 as zero. A W-2 employee with a losing Etsy shop still owes New Jersey tax on the full salary, with only the NJ-BUS-2 adjustment to recover part of the loss.
New Jersey counts interest by the month or part of a month. A September 15 installment paid on October 16 is charged two months, the same as one paid on November 15.
New Jersey's prior-year anchor is 100% at every income level, and its current-year test is 80%. Mirroring the federal 110% rule prepays a tenth of last year's tax for no extra protection.
New Jersey's estimate depends on a profit figure that has to be rebuilt from Schedule C, and on health insurance and other deductions you pay through the year. Jupid connects to your bank accounts and categorizes each transaction with 95.9% accuracy, so client income, health premiums, and personal spending sit in separate places all year. Ask the AI accountant in WhatsApp or iMessage what your business has earned so far in 2026, and you have the profit line for the NJ-1040-ES worksheet before the January voucher is due. Try Jupid.
