Accounting firms in New Jersey: 3,754 offices, 2,591 registered CPA firms by county, and a big payroll industry

New Jersey is one of the few states where you can count its CPA firms directly: the state publishes its whole firm register as a free download. It also has an accounting industry that's unusually heavy in payroll processing, which employs more people here than bookkeeping and tax preparation combined.

It combines the Census count with the state's own firm register, explains how to check a firm, and closes with how to prospect them.

CBP counts establishments with paid employees, not companies, and leaves out the self-employed.

County by county: Census offices and registered firms

The first two columns are CBP 2023 for NAICS 5412. The third counts active accountancy firm registrations by county from the state's bulk license roster, downloaded on 30 October 2026.

CountyOffices (CBP)Employees (CBP)Active CPA firm registrations

Camden1751,064116

Another 13 establishments with 7,396 employees are coded statewide, with no county. The two sources measure different things: CBP counts every accounting, tax, bookkeeping and payroll office with employees; the register counts accountancy firms registered with the state, whether or not they have staff. Most active registrations run to 30 June 2027.

Payroll is New Jersey's distinctive segment

Type (NAICS 2022)OfficesEmployeesPay per employee
CPA offices (541211)1,80121,284$126,666
Payroll services (541214)19512,668$105,842
Other accounting, including bookkeeping (541219)1,0795,637$57,855
Tax preparation (541213)6792,986$23,392

Payroll offices average 65 employees, and the state is home to ADP, whose 10-K for the year to June 2026 gives its principal executive offices as Roseland, Essex County. SEC EDGAR files ADP under computer processing (SIC 7374), not accounting; EDGAR has no accounting industry code, so there are no listed accounting firms to rank. The largest accounting firms are private partnerships; see the Big 4 accounting firms.

Pay per employee is our calculation. Tax preparation reads low because CBP counts staff in the week of March 12, at the peak of filing season.

Which to hire depends on the job. A bank covenant, an investor or a grant that asks for audited or reviewed statements needs a registered CPA firm. Monthly books and invoicing usually go to one of the 1,079 bookkeeping and other accounting offices, at lower rates. A payroll service runs paychecks and payroll tax filings and a tax preparation office does returns; by the Census definitions, neither keeps your books.

How to check a New Jersey firm or preparer

  1. Search the license. The Division of Consumer Affairs' license verification system covers CPAs and accountancy firms; firms are licensed in the business's name, so search the firm name, not a partner's.
  2. Download the register if you need many. The same system offers a free bulk roster by profession and license type, as a delimited text file.
  3. Match the credential to the job. Audits and reviews need a CPA firm. For IRS representation in an audit or collection case, you need a CPA, enrolled agent or attorney.
  4. Check the preparer. The IRS's August 2026 preparer listing, released under the Freedom of Information Act, has 23,326 preparers with New Jersey business addresses: 7,968 CPAs, 2,215 enrolled agents and 665 attorneys; 11,526 (49%) hold no IRS credential and no Annual Filing Season Program record.
  5. Avoid refund-percentage fees, which the IRS warns against.

For a public company or broker-dealer audit, the firm must be registered with the PCAOB; 646 US firms were at the end of 2025.

Selling to New Jersey accounting firms

Illustrative example. The company and rates are invented; the counts come from the state register and CBP.

Garden Ledger (gardenledger.example) sells document and e-signature software to CPA firms. It downloads the register's 2,591 active in-state firms, starts with Bergen, Morris and Monmouth (993 firms), and drops firms whose website shows a single practitioner, an illustrative 45%, leaving about 546. It writes to the managing partner in late October, before year-end planning, then follows up in May. At an illustrative 5% reply rate, that's 27 conversations from three counties.

The register gives the firm's name and county, not who decides; the list of accounting firms explains firm roles, and how many accountants there are covers the IRS file. Finding the managing partner and recent changes at each firm is the slow part; Bebop researches each account.
