Partnerships and S corporations

Pass-Through Business Alternative Income Tax (BAIT/PTE): elective entity-level tax for partnerships, S corps and multi-member LLCs with at least one individual/estate/trust member; election and Form PTE-100 due by the original due date, March 15 for calendar-year filers; annual election; six-month extension via PTE-200-T with 80% paid; quarterly estimates (PTE-150) if liability exceeds $400; rates 5.675% to 10.9%; members get a refundable credit. Partnerships with more than two owners and NJ-source income also owe a $150-per-owner filing fee (cap $250,000) plus a 50% installment toward next year, both due with NJ-1065 by the 15th day of the 4th month.

Sales and Use Tax, statewide rate 6.625%

Due date. Quarterly return (Form ST-50) due on or before the 20th day of the month following the end of the calendar quarter (Apr 20, Jul 20, Oct 20, Jan 20); monthly remittance (ST-51) for the 1st and 2nd months of a quarter due the 20th of the following month. Next business day if the 20th falls on a weekend/holiday.

Filing frequency. All registered sellers file quarterly ST-50 returns (even with no tax due). Sellers that collected more than $30,000 in NJ sales and use tax in the prior calendar year must additionally remit monthly (ST-51) for the first and second months of each quarter when the tax due for that month exceeds $500.

Thresholds. Monthly remittance: > $30,000 collected in preceding calendar year AND > $500 due for the month. Economic nexus for remote sellers: > $100,000 NJ gross revenue or 200+ transactions.

Prepayments. No separate prepayment program found; the accelerated schedule is the ST-51 monthly remittance for large filers described above.

Notes

CBT-100 due date rule changed for privilege periods ending on/after 7/31/2020 (now May 15 for calendar-year C corps; CBT-100S unchanged at April 15). Change effective 2024+: 2.5% Corporate Transit Fee on taxable net income over $10M for 2024-2028 (P.L. 2024, c.20); the prior 2.5% surtax expired after 2023. Estimated CBT installments due 15th day of 4th/6th/9th/12th months when liability exceeds $500.

What we could not confirm. No reputable secondary source was fetched for the BAIT/PTE-100 March 15 due date (only the official BAIT page; the PTE-100 instructions PDF path 404'd). The NJ-1065 five-month extension length was confirmed from official instructions but not from a secondary source. Annual-filer sales tax option (if any) was not confirmed. A third-party site (taxextension.com) listed conflicting NJ due dates and was disregarded.
