If you work for yourself in New Jersey, it may surprise you that nobody takes tax out of your income before it reaches you.
Back when you had a regular paycheck, your employer quietly sent a slice of every check to the state for you. Now that you own the business, sending that slice is up to you, and New Jersey would like it in four installments during the year rather than all at once in April.
Those installments are called NJ estimated tax payments.
With 2026 almost wrapped up, this is a good moment to get them right for 2027, so we’ll start with whether you need to make them at all, then go through the 2027 dates, how much to send, and the one 2026 payment you still have left in January.
Do You Have to Make NJ Estimated Tax Payments?
If you expect to owe New Jersey more than $400 for the year, after whatever’s already been withheld and any credits, the answer is yes. That’s the line the Division of Taxation draws in its GIT-8 guide to estimating income taxes, and it applies whether you live in New Jersey or just earn money here.
Since $400 isn’t much, almost anyone whose business profit lands on their personal return ends up making these payments. That includes owners running things solo, LLC owners, partners, and S corporation shareholders. If you also have a job on the side, the tax withheld from that paycheck helps, but it rarely covers the business income too.
The part that catches people is that New Jersey’s line sits well below the federal one. The IRS generally expects estimated payments once you’ll owe $1,000 or more, and GIT-8 says outright that you may owe New Jersey estimates even when you don’t owe federal ones. So it’s worth checking your New Jersey number on its own, even if the IRS has never asked you for a quarterly payment.
Once you know you’re in, the next question is when the money is due.
The 2027 Due Dates Follow the Same Pattern as Every Year
The good news is that New Jersey’s calendar barely changes from year to year. For 2027, you can plan on April 15, June 15, and September 15, 2027, with the last payment landing in January 2028.
That January payment comes with a small wrinkle. January 15, 2028, falls on a Saturday, and New Jersey’s rule is that a payment due on a weekend or legal holiday slides to the next business day. The 2027 payment forms, called NJ-1040-ES vouchers, will have the exact date printed on them, so double-check it there before you put it in your calendar.
If your business runs on a fiscal year that ends somewhere other than December 31, your dates shift to match your own year. Most of the small businesses we work with use the calendar year, though, so the dates above are the ones to plan around. With the dates set, the bigger question is how much to send each time, and there are two ways to work it out.
How Much Should You Send Each Quarter in 2027?
New Jersey asks you to pay in at least the smaller of two amounts over the year: 80% of your 2027 New Jersey tax, or 100% of your 2026 New Jersey tax. Whichever is lower is your target, and you spread it across the four payments.
The 2026 number is usually the easier one to work with, because it’ll be sitting right there on the return you file next spring. If your business is fairly steady, you can divide it by four and you’re most of the way there.
Say your 2026 New Jersey return shows $8,000 of tax. You could send $2,000 on each of the four 2027 due dates. If 2027 then turns out to be a great year and your tax comes to $12,000, you still wouldn’t owe interest for paying too little during the year, and you’d simply pay the difference when you file. The Division calls this Exception 1, and it works as long as you filed a full-year New Jersey return for 2026 that showed tax owed and you make all four equal payments on time.
The 80% route is worth the extra effort when you expect 2027 to be a slower year than 2026, because paying last year’s amount would mean sending in more than you’ll actually owe. It does take a real projection of the year, and we like to build that from your actual books.
A guess made in April has a way of looking pretty different by September.
Your Payments Can Change When Your Income Does
Whichever route you pick, you aren’t locked into it. GIT-8 says that if your income goes up or down during the year, you can adjust your remaining payments to match, and the voucher instructions even include a worksheet for refiguring them.
That flexibility matters most for seasonal businesses. If you run a landscaping business that does most of its work between spring and fall, or you’re a contractor who lands one big job in August, four equal payments probably won’t match how your money actually comes in.
New Jersey has a method for exactly that situation called annualizing, which is Exception 3 on Form NJ-2210. Instead of assuming your income arrived evenly, it looks at what you really earned in each payment period. If most of your income came in late in the year, it can lower or remove the interest on those early payments.
Once you know how much to send, actually sending it is the easy part.
Paying Online Takes a Few Minutes and No Voucher
The quickest way to pay is through the Division’s Pay Tax page, either by e-check, which pulls the money straight from your bank account, or by credit card. You won’t need the paper voucher for either one, just your Social Security number and date of birth. Card payments come with a fee, and e-checks have to come from a U.S. bank.
Our favorite part is that you can schedule e-check payments ahead of time. If you set up all four 2027 payments in the spring, the due dates can’t sneak up on you, and you can still adjust the later ones if the year takes a turn.
If you’d rather mail a check or money order, send it with that quarter’s NJ-1040-ES voucher, which has your Social Security number on it so the state knows whose payment it is.
What Happens If You Pay Too Little During the Year?
If you pay in less than your target during the year, through withholding and on-time estimates, New Jersey charges interest on the shortfall. The rate is 3% above the prime rate, which is the base rate banks use for lending, and it runs from each missed due date until you catch up, up to April 15.
It surprises a lot of owners that paying everything by April 15 doesn’t make that interest go away. GIT-8 says the interest still applies, because what counts is how much came in during the year.
Form NJ-2210 lists four exceptions that can take the interest off for a given quarter, including Exception 1 and Exception 3. Things work a little differently when your business pays part of the tax for you, and that’s where BAIT comes in.
BAIT Payments Are Separate From Your Personal Estimates
Some partnerships and S corporations choose to pay New Jersey income tax at the business level instead of leaving it all to the owners. New Jersey calls this the Pass-Through Business Alternative Income Tax, or BAIT, and we went through how it works in our post on what New Jersey’s BAIT is. A business that chooses BAIT makes its own estimated payments on Form PTE-150 once its BAIT is more than $400, on the same four dates.
It’s easy to assume those payments cover you personally, but the Division’s BAIT page says they’re separate from your NJ-1040-ES payments. You do get a credit for your share on your personal return, which lowers your New Jersey tax dollar for dollar. Even so, the BAIT FAQ warns that owners may still need personal estimates for other income, like investments.
If BAIT is part of your 2027 plan, there’s one timing detail to know. The business has to choose BAIT again every year, and New Jersey won’t accept any BAIT payment, estimates included, until that election is in place. So if your business wants to pay as it goes in 2027, the election needs to come before the first payment. Single-member LLCs and sole proprietors can’t use BAIT at all.
Start With January 15, Then Set Up Your 2027 Payments
Before 2027 gets going, there’s still one 2026 payment on the calendar. The fourth 2026 NJ-1040-ES voucher is due January 15, 2027, and it covers the last few months of the year. If your business had a strong fall, that payment may need to be bigger than the first three. And if you should have been paying all year and haven’t started yet, New Jersey expects the missed payments to come in with your first one.
That makes this winter a great time to sort out both years at once. When your bookkeeping is up to date, we can work out the January payment and your four 2027 payments in one sitting, and handle the federal side while we’re at it. We wrote more about planning like this all year long in our post on year-round tax planning.
If you’re self-employed and still figuring out the federal side, our step-by-step guide to filing self-employment taxes is a good next read.
