NJ Extension Rules by Entity Type
Extensions extend filing time only, never payment time. Interest accrues on any unpaid balance from the original due date.
| Entity | NJ Extension Form | Payment Required | Auto-Honor Federal? | Extension Length |
|---|---|---|---|---|
| Individual (NJ-1040) | NJ-630 (or auto w/ federal 4868) | 80% of tax liability | Yes | 6 months |
| C-Corp / S-Corp | CBT-200-T (must file separately) | 90% of tax liability | No | 6 months |
| Partnership (NJ-1065) | PART-200-T (auto w/ federal 7004) | 80% of filing fee | Yes | 5 months |
| BAIT (PTE-100) | PTE-200-T | 80% of tax liability | No | 6 months |
The BAIT election itself cannot be extended, only the PTE-100 return filing. If the extension payment threshold is not met, the extension is retroactively denied and late filing penalties apply.
Estimated Tax Safe Harbors
Meet these thresholds to avoid underpayment penalties. NJ's individual safe harbor (80%) is more generous than the federal (90%).
| Tax Type | Current-Year | Prior-Year | High-Income (>$150K) |
|---|---|---|---|
| NJ Individual (GIT) | 80% | 100% | 110% |
| NJ BAIT | 80% | 100% | - |
| NJ CBT | 90% | 100% | - |
| Federal Individual | 90% | 100% | 110% |
NJ Tax Rate Reference Tables
Key NJ rate tables that directly affect deadline planning: BAIT rates, CBT minimums, CBT estimated payment thresholds, and payroll deposit frequency rules.
BAIT Tax Rates (TY 2022 Forward)
| Distributive Proceeds | Rate |
|---|---|
| $0 - $250,000 | 5.675% |
| $250,001 - $1,000,000 | 6.52% |
| Over $1,000,000 | 10.9% |
Single-member LLCs and sole proprietorships are excluded from BAIT. Election must be made by the original PTE-100 due date (March 16, 2026 for calendar-year filers) and cannot be made retroactively. See NJ BAIT Election Guide.
NJ CBT Minimum Tax by Gross Receipts
| NJ Gross Receipts | Minimum Tax |
|---|---|
| Under $100,000 | $500 ($375 for S-corps) |
| $100,000 - $249,999 | $750 |
| $250,000 - $499,999 | $1,000 |
| $500,000 - $999,999 | $1,500 |
| $1,000,000+ | $2,000 |
Affiliated groups with total payroll of $5M+ owe $2,000 minimum regardless of gross receipts. Even inactive corporations must pay minimum tax. Top CBT rate is 9% plus 2.5% Corporate Transit Fee for C-corps with NJ allocated income >$10M (TY 2024-2028), creating an effective 11.5% top rate. S-corps and public utilities are exempt from the Transit Fee.
CBT Estimated Payment Rules (Form CBT-150)
| Installment | Due Date | Standard (<$50M) | Large Filer (≥$50M) |
|---|---|---|---|
| 1st | April 15 | 25% | 25% |
| 2nd | June 15 | 25% | 50% |
| 3rd | September 15 | 25% | Skipped |
| 4th | December 15 | 25% | 25% |
Quarterly CBT installments are mandatory when prior-year tax exceeds $1,500 (C-corps) or $375 (S-corps). Below these thresholds, a single 50% prepayment of prior-year tax may be made instead. CBT safe harbor requires 90% of current-year tax or 100% of prior-year tax, stricter than the individual/BAIT 80% safe harbor.
NJ Withholding Deposit Frequency
| Frequency | Trigger | Due Date | Form |
|---|---|---|---|
| Weekly | Prior-year NJ withholding ≥ $10,000 | Wednesday following payroll week | NJ-927-W |
| Monthly | Monthly withholding ≥ $500 in first two months of quarter | 15th of following month | NJ-500 |
| Quarterly | Monthly withholding < $500 | 30th of month after quarter (with NJ-927) | NJ-927 |
Weekly payers must remit via EFT and file Form NJ-927-W (not the standard NJ-927). NJ uses the 30th of the month, not the 31st, differing from federal Form 941 (due the last day of the month: Apr 30, Jul 31, Oct 31, Jan 31). NJ-927-H (domestic employer annual return) is due January 31.
7 Deadline Mistakes That Cost NJ Taxpayers
Missing the BAIT election deadline
The PTE-100 and BAIT election must be filed by March 16, 2026. This is a hard, non-extendable deadline; miss it and the entity cannot elect BAIT for the entire tax year. No retroactive cure exists.
Assuming NJ honors the federal corporate extension
NJ automatically honors federal extensions for individual and partnership returns, but NOT for corporate returns. CBT-200-T must be filed separately with 90% of tax liability paid. Failing to file it means no NJ extension, even if a federal Form 7004 exists.
Using the federal due date for NJ business returns
NJ CBT returns trail federal by one month. The CBT-100S is due April 15 (not March 16), and the CBT-100 is due May 15 (not April 15). Filing on the federal due date results in a late filing, or worse, filing a month early and missing last-minute adjustments.
Not making NJ estimated payments at the $400 threshold
NJ requires estimated payments when the expected balance due exceeds $400 (lower than the federal $1,000 threshold). Many taxpayers who don't need to make federal estimated payments still owe NJ estimated payments.
Forgetting the NJ-W-3 by February 15
The annual NJ reconciliation of GIT withheld falls between W-2 distribution (January 31) and the filing season rush. It's easily overlooked, and discrepancies between NJ-927 totals and the NJ-W-3 trigger notices.
Not paying enough with the NJ extension
NJ requires 80% of tax liability paid for a valid individual extension. If this threshold is not met, the extension is retroactively denied and late filing penalties apply from the original due date, not the extended date.
Missing the December 15 CBT estimated payment
The NJ CBT 4th-quarter estimated payment is due December 15: a full month earlier than the individual/BAIT January 15 payment. This catches business owners who expect all Q4 payments to share the same date.
NJ Penalty & Interest Reference
NJ's cost of late payment is among the steepest in the region.
| Penalty Type | Rate | Notes |
|---|---|---|
| Late filing | 5% per month, max 25% + $100/mo | Applies after due date or extended due date |
| Late payment | 5% flat (one-time) | Separate from late filing; both can apply |
| Underpayment interest | 10.00% (2026) | Prime + 3%, compounded annually, from original due date |
| Collection referral | 11% of total debt | Added if debt sent to outside collection |
NJ's flat 5% late payment penalty is significantly harsher than the federal 0.5%-per-month penalty. Combined with the 10% interest rate, NJ penalties can exceed 15% of the unpaid amount within the first year.
