New Jersey Administrative Code
Title 18 - TREASURY - TAXATION
Chapter 24 - SALES AND USE TAX ACT
Subchapter 11 - OBLIGATION TO COLLECT AND PAY SALES TAX OR COMPENSATING USE TAX
Section 18:24-11.2 - Filing of monthly remittance and quarterly returns

(a) All sellers required to collect and remit sales and use tax are required to file a Sales and Use Tax Quarterly Return (Form ST-50) with the Division of Taxation on or before the 20th day of the month following the quarter covered by the return. In calculating the amount of tax to be remitted to the Division of Taxation for the quarterly period, the seller shall be entitled to a credit in the amount of tax remitted as monthly remittances for the months of the quarter covered by the quarterly return.

(b) Effective July 1, 1996 through August 2, 2009, with respect to sales and use tax liabilities incurred on and after July 1, 1996 through August 2, 2009, every seller with liability exceeding $ 500.00 for the first or second month of a quarterly filing period shall, on or before the 20th day of the month following each such month, file with the Director a Monthly Remittance Statement (Form ST-51) and pay an amount equal to its liability for the month. Any payment due for the calendar months of March, June, September, or December shall be paid with the quarterly return filed for the quarter in which such month falls.

(c) Effective August 3, 2009, sellers that collect more than $ 30,000 in sales and use tax in New Jersey during the preceding calendar year must file a monthly remittance for the first and second months of each calendar quarter if the amount of tax due for that month exceeds $ 500.00. See 18:24B-1.4. If less than $ 30,000 in sales and use tax is collected by the seller in New Jersey during the preceding calendar year, a monthly remittance is not required to be remitted regardless of the amount of tax due for that particular month.

(d) Only a single return is required to be filed for each taxing period for each seller.

(e) Returns are due on the 20th day of the month following the month in which the transaction occurred. When the due date for a return falls on a Saturday, Sunday, or legal holiday in New Jersey, the return shall be due on the next business day. If the return is filed in conjunction with a remittance and the remittance cannot be made because the Federal Reserve Bank is closed on a due date that prohibits a person from being able to make a payment by the automated clearing house (ACH) debit or credit, the return shall be accepted as timely filed on the same day as the remittance.
