How to Choose a Bookkeeper in New Jersey (2026)

Choosing a bookkeeper in New Jersey comes down to three checks you can do in an afternoon: the firm's registration, any CPA license it claims, and a written fee with a close date. The third is the one most New Jersey firms leave to a call, since only 4 of the 79 we list put a price on their sites.

What a New Jersey bookkeeper keeps track of

These are the state filings your books feed in New Jersey. Which ones apply depends on your entity type, what you sell, whether you have employees and the schedule each agency assigns. It's general information, not tax advice. The bookkeeper keeps the records; you, or whoever your engagement letter names, file.

• Sales and use tax. Registered sellers file Form ST-50 every quarter, even when no tax is due. Monthly payments apply only if you collected more than $30,000 in New Jersey sales and use tax last calendar year and more than $500 in the first or second month of the quarter. Returns and payments are due by the 20th of the month after the period. Source: New Jersey Division of Taxation, checked September 26, 2026.
• Income tax withholding. All employers except domestic employers file Form NJ-927 each quarter, even with no tax withheld, due by the 30th of the month after the quarter ends. If more than $500 was withheld in the first or second month of a quarter, that month is paid separately on Form NJ-500. Filing and payment are electronic.

• Unemployment wage reports. Employers file the WR-30 wage report with the Department of Labor and Workforce Development each quarter, listing everyone paid as an employee. The NJ-927, WR-30 and any payment must arrive by the 30th of the month after the quarter closes: April 30, July 30, October 30 and January 30.

• Annual report. Your New Jersey business files an annual report each year with a $75 fee. It's due by the last day of the month in which the business was formed, and the duty to file stands even if the State sends no notice. Source: Business.NJ.gov, checked September 26, 2026.
• CPA title. Only a person holding a current New Jersey CPA license, or qualifying for the practice privilege, may use the title certified public accountant or the abbreviation CPA. Source: New Jersey Legislature, checked September 26, 2026.

How to check a New Jersey firm yourself

The New Jersey business entity search shows whether the firm's legal entity exists and its status. A sole proprietor may not appear, which isn't a warning sign on its own. New Jersey publishes these records as open data, so our lists already carry the checks: we matched an active CPA license or permit for 27 firms of the 79 New Jersey firms we list. Matched CPA records include Martini & Martini, MH Financial CPA Firm, CSI Group CPA, PRECISION ACCOUNTING INTL LLC and Alto CPA Group, LLC.
