How to File New Jersey Form CBT-200-T: Deadline, Payment, and Minimum Tax

New Jersey Form CBT-200-T is the Corporation Business Tax Tentative Return and Application for Extension of Time to File. Submit it electronically by your return’s original due date, pay at least 90 percent of your estimated full-year tax, and your corporation gets an automatic six-month extension to file the CBT-100, CBT-100S, or CBT-100U.¹ The extension moves the filing deadline only. The tax is still due on the original date, and interest runs on anything unpaid after it.

When the Extension Is Due

For privilege periods ending on or after July 31, 2023, the New Jersey CBT return is due on the 15th day of the month following the month of the federal due date.² A calendar-year C corporation with an April 15 federal deadline owes its New Jersey return, and its CBT-200-T, on May 15. Fiscal-year filers apply the same rule to their own federal date.

If the deadline lands on a weekend or state holiday, it rolls to the next business day. Miss it by a day and the extension is invalid; the Division of Taxation treats the eventual return as late from the original due date, not from when you tried to extend.

Note that New Jersey does not accept the federal Form 7004 as a substitute. A federal extension with the IRS does nothing for your state obligation — you file the CBT-200-T through New Jersey’s own system.¹

What You Have to Pay for the Extension to Count

The CBT-200-T is short, but the number on the bottom line decides whether your extension survives. The Division requires that at least 90 percent of your actual annual liability be paid by the original due date.¹ Underestimate and the extension is denied retroactively. Build a cushion.

The form has eight lines.³

Line 01, Estimated Corporation Business Tax: your best estimate of full-year tax. Start from last year’s return and adjust for changes in income, allocation factors, or rates.
Line 02, Installment Payment: 50 percent of Line 01.
Line 03, Key Corporation AMA: the Alternative Minimum Assessment, if it applies.
Line 04, Tentative Professional Corporation Fee: law firms, medical practices, accounting firms, and similar entities only.
Line 05, Installment Payment for PC Fee: 50 percent of Line 04.
Line 06, Total Tax and Fee Due: Lines 01 through 05 added together.
Line 07, Less Payments Made to Date: estimated installments already paid and any prior-year overpayment credited forward.
Line 08, Balance Due: Line 06 minus Line 07. This is what you send with the form.

Round every dollar figure to the nearest whole dollar — drop under 50 cents, round up at 50 cents or more.³

Rates for Estimating Line 01

New Jersey’s Corporation Business Tax rate depends on entire net income:⁴

$50,000 or less: 6.5 percent of allocated net income
Over $50,000 but not more than $100,000: 7.5 percent
Over $100,000: 9 percent

Corporations with allocated net income over $10 million may also owe an additional 2.5 percent surcharge enacted in 2024, bringing the effective top rate to 11.5 percent. Check the current CBT-100 instructions for the threshold and applicability window, since surcharges have historically been set to expire after a defined period.

Minimum Tax Floor

Every corporation owes at least a minimum tax based on New Jersey gross receipts, even if net income is zero.⁴ Your Line 01 estimate should never fall below the floor for your bracket.

C corporation minimum tax:

Gross receipts under $100,000: $500
$100,000 to under $250,000: $750
$250,000 to under $500,000: $1,000
$500,000 to under $1,000,000: $1,500
$1,000,000 or more: $2,000

S corporation minimum tax:

Gross receipts under $100,000: $375
$100,000 to under $250,000: $562.50
$250,000 to under $500,000: $750
$500,000 to under $1,000,000: $1,125
$1,000,000 or more: $1,500

Any corporation in an affiliated or controlled group with total payroll of $5 million or more owes a $2,000 minimum regardless of its own gross receipts.⁴

How to File and Pay Online

New Jersey mandates electronic filing for all Corporation Business Tax returns, extensions, estimated payments, and vouchers.⁵ File the CBT-200-T through the Corporation Business Tax Online Filing and Payments system on the Division of Taxation’s website.¹

To log in, use your twelve-digit taxpayer identification number: the nine-digit Federal Employer Identification Number plus a three-digit suffix. If no suffix has been assigned, enter three zeros.⁶ The system pre-fills your company name, address, FEIN, reporting period, and return due date.³ Enter Lines 01 through 08, then move to the payment screen.

Accepted payment methods are electronic funds transfer, e-check, and credit card.⁵ An e-check requires your bank routing and account numbers. Credit card payments route through a third-party processor that charges a convenience fee, typically a percentage of the payment. After the payment clears, the system issues a confirmation number. Save it. That number is your proof of timely filing if anything is later disputed.

If electronic filing is genuinely impossible, paper checks can be mailed to the New Jersey Division of Taxation, PO Box 666, Trenton, NJ 08646-0666.⁷ The electronic mandate is broadly enforced, so treat paper as a last resort.

Combined Groups and S Corporations

If your corporation is part of a combined filing group, the managerial member files one CBT-200-T covering the whole group and pays the tentative tax for all taxable members. Individual members do not file separate extensions.¹ The managerial member must be registered with the Division of Taxation as the group’s filer before the combined CBT-100U can be submitted.⁸ Handle that registration before the extension deadline so the online system can process the filing under the correct account.

S corporations use the same CBT-200-T but will file a CBT-100S instead of a CBT-100. For privilege periods beginning on or after December 22, 2022, a federal S corporation can file as a New Jersey S corporation without a prior state election by submitting a Shareholder Jurisdictional Consent and proof of federal S corporation status.⁹ When estimating Line 01, apply the S corporation minimum (starting at $375) rather than the C corporation schedule. Shareholders that have elected to treat the entity as a C corporation for New Jersey purposes use the C corporation rates and minimums.

What Happens If the Extension Fails

Miss the original due date, or pay less than 90 percent of the actual liability, and the extension is denied. The Division then treats your eventual return as late from the original due date, not from the extended one.¹

Late filing triggers a penalty of $100 per month or partial month the return is overdue, plus 5 percent per month of the unpaid tax, capped at 25 percent.¹⁰ If no return is filed within 30 days after the Division sends its first delinquency notice, the 5 percent monthly penalty applies to total tax liability rather than just the unpaid balance.

Interest compounds on top of penalties. New Jersey charges interest at three percentage points above the prime rate, compounded annually.¹¹ For the 2026 calendar year that rate is 10.00 percent, a 7.00 percent prime rate plus the 3 percent statutory add-on.¹² Interest accrues from the original due date on any amount that remains unpaid.

Even a valid extension does not stop interest from running between the original due date and the day you actually pay. The extension waives the late-filing penalty. It does not waive interest. This is the most common misunderstanding about the CBT-200-T: it buys time to prepare paperwork, not time to come up with money.

After You File

The Division of Taxation does not send a confirmation letter or formal approval. The extension takes effect automatically once a valid CBT-200-T is submitted with a tentative payment of at least 90 percent of the eventual liability.¹ Your online confirmation number is the only record you will have, so store it where you can find it.

Check your bank account to confirm the payment actually cleared. A rejected e-check or declined credit card means the tentative payment never went through, which voids the extension even though the form was submitted. If something failed, resubmit before the deadline passes.

The full CBT-100, CBT-100S, or CBT-100U is then due six months after the original filing date. For a calendar-year filer with an original May 15 due date, the extended deadline is November 15. On that final return, report the tentative payment from the CBT-200-T as a credit against total tax, and either pay any remaining balance or claim a refund for an overpayment.
