The New Jersey Corporation Business Tax applies to every domestic and foreign corporation exercising its corporate franchise in the state, at graduated rates of 6.5% to 9% on net income allocated to New Jersey.1Justia. New Jersey Code 54:10A-1 – Short Title Even a corporation with no taxable income owes a minimum tax between $375 and $2,000 depending on gross receipts and entity type. Returns are due on the 15th day of the fourth month after the tax year ends, must be filed electronically, and must include a complete copy of federal Form 1120.
Which Corporations Owe the Tax
The tax reaches standard C corporations, S corporations, professional corporations, and LLCs that have elected corporate tax treatment.2Justia. New Jersey Revised Statutes Section 54:10A-5 – Franchise Tax A physical office in New Jersey is not required. The nexus standard covers any entity doing business in the state, deriving receipts from state sources, engaging in contacts within the state, or owning property here.3New Jersey Division of Taxation. Nexus for Corporation Business Tax In practice, the Division of Taxation looks at the nature and frequency of your activities in the state, whether you employ people here, and where management decisions happen.
S corporations file on Form CBT-100S and generally owe only the minimum tax. Any income taxed at the federal level, however, is also taxed by New Jersey at the regular graduated rates.4New Jersey Division of Taxation. 2025 CBT-100S Instructions One S corporation wrinkle: income allocated to nonconsenting shareholders is taxed at 10.75%, well above the standard rates.
Rates on Entire Net Income
New Jersey taxes corporate income in three brackets based on entire net income allocated to the state:5New Jersey Division of Taxation. Corporation Business Tax Overview
- 6.5% on entire net income of $50,000 or less
- 7.5% on entire net income above $50,000 but not exceeding $100,000
- 9% on entire net income above $100,000
New Jersey previously imposed a 2.5% temporary surtax on corporations with more than $1 million in allocated taxable income. That surtax expired at the end of 2023 and does not apply to current privilege periods.6New Jersey Division of Taxation. Surtax
Minimum Tax Even When You Owe Nothing on Income
Every corporation owes at least a minimum tax, whether or not it reports taxable income. The amount tracks New Jersey gross receipts. For C corporations:2Justia. New Jersey Revised Statutes Section 54:10A-5 – Franchise Tax
- Less than $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 corporations pay lower minimums, starting at $375 for gross receipts under $100,000 and topping out at $1,500 for gross receipts of $1 million or more. Watch this rule if your corporation is part of an affiliated or controlled group: when the group’s total payroll is $5 million or more, every member owes the $2,000 minimum regardless of its individual gross receipts.7New Jersey Division of Taxation. 2025 CBT-100 Instructions
How Multistate Income Is Allocated to New Jersey
A corporation operating in more than one state does not pay New Jersey tax on its entire worldwide income. The state uses a single sales fraction to decide how much of the income is allocated here: New Jersey gross receipts divided by total gross receipts everywhere.5New Jersey Division of Taxation. Corporation Business Tax Overview
New Jersey phased in this single sales factor between 2012 and 2014, replacing an older three-factor formula that also weighted property and payroll. Since January 1, 2014, property and payroll play no role in allocation. Companies with substantial New Jersey workforce or physical assets but most of their revenue elsewhere benefit, because only the revenue factor counts. A company with few New Jersey employees but heavy in-state sales cannot dilute its allocation with an out-of-state payroll factor anymore.
Combined Reporting for Unitary Groups
For tax years ending on and after July 31, 2019, New Jersey requires mandatory combined reporting when corporations are part of a unitary business group.8New Jersey Division of Taxation. Combined Group Filing Methods A combined return is a single filing for a group of related entities operating as one economic enterprise.
The default method is water’s-edge, which generally includes only domestic entities and certain foreign entities with meaningful U.S. connections. The managerial member of the group can instead elect worldwide reporting, which pulls in all foreign affiliates, or file as an affiliated group as defined by the statute. Whichever method is chosen, the group calculates net operating losses and tax credits under the same set of rules. A corporation that has New Jersey nexus but is not in a unitary relationship with the group files its own separate return.
Filing, Deadlines, and Extensions
Electronic filing is mandatory for all Corporation Business Tax returns and payments. There is no opt-out.9New Jersey Division of Taxation. Corporation Business Tax Electronic Filing and Payment Mandate You can file through the state’s online service or third-party tax preparation software. Payments go through the state’s online CBT portal by electronic funds transfer, e-check, or credit card.
The return is due on the 15th day of the fourth month after your tax year ends. For a calendar-year filer, that is April 15. The state grants a six-month extension of time to file, but there is no extension of time to pay. A tentative tax payment goes in with the extension request, and if less than 90% of the liability is paid by the original due date, the extension is denied and penalties begin.10New Jersey Division of Taxation. Corporate Business Tax – Extensions
Attach a complete copy of federal Form 1120 to the state return. The Division of Taxation uses it to reconcile federal taxable income with New Jersey adjustments. A missing attachment can trigger a rejection or a deficiency assessment.
Estimated Tax Installments
Corporations that expect to owe more than the minimum tax must make installment payments during the year. The schedule depends on entity type and prior-year gross receipts.11New Jersey Division of Taxation. Installment Payments of Estimated Tax
For a C corporation with prior-year gross receipts under $50 million and a liability above $500, four equal installments of 25% are due on the 15th day of the 4th, 6th, 9th, and 12th months of the tax year. When prior-year gross receipts hit $50 million or more, the schedule shifts to 25% in the 4th month, 50% in the 6th month, and 25% in the 12th month. S corporations follow a similar structure, with the threshold for mandatory installments set at $375 instead of $500.
A corporation whose total liability falls at or below the minimum tax threshold can either make four equal installments or a single prepayment of 50% by the return due date.
Penalties for Filing or Paying Late
Missing the deadline is expensive. New Jersey imposes a late filing penalty of 5% per month, or any part of a month, on the unpaid tax balance, capped at 25%. A flat $100 per month penalty also accrues for every month the return is overdue.12State of New Jersey. New Jersey Tax Debt – Type Selection Late payment carries a separate 5% penalty on the unpaid balance, and interest accrues on any outstanding amount from the original due date.
These penalties stack. A corporation that files three months late and has not paid owes 15% in late filing penalties, $300 in flat monthly penalties, plus the 5% late payment penalty and interest. Filing an extension avoids the late filing penalty only if at least 90% of the tax is prepaid by the original deadline.
Research and Development Expenses
New Jersey has decoupled from the federal requirement under Section 174 of the Internal Revenue Code to amortize research and experimental expenditures over five years. For New Jersey qualified research expenditures, a corporation can deduct the full amount in the year the expense is incurred rather than spreading the deduction over multiple years as required on the federal return.13New Jersey Division of Taxation. Timing of New Jersey Qualified Research Expenditures Corporations claiming the state’s R&D tax credit can also deduct the underlying expenses in the same year as the credit.
This favorable treatment applies only to expenditures that qualify as New Jersey expenditures. Non-New Jersey qualified research expenses follow the federal amortization schedule and must be spread over the same period required on the federal return. The distinction matters for multistate companies that conduct research inside and outside New Jersey. Record these amounts carefully as “other deductions” on Schedule A of the return.
Keeping Records
New Jersey requires corporations to maintain copies of filed returns, supporting schedules, and payment confirmations. The state’s administrative code under N.J.A.C. 18:18A-7.1 addresses retention, and the general practice is to keep records for at least seven years from the filing date. Because the state can assess deficiencies for prior periods, storing digital copies of each year’s CBT return and all attached federal forms for at least that long is the safest approach.
