How to find a CPA in California and compare the fit

How to find a CPA in California starts with a simple comparison. Confirm the credential that matters for the work, ask how the firm will handle your records and communication, then compare the same answers from each candidate. A good choice for a business is someone whose scope, working style and authority are clear before documents change hands.

This page does not rank firms or name a winner. It gives you a worksheet for choosing among the people you are already considering. Save each answer beside the candidate’s name. The useful result is a decision you can explain to your co-owner, office manager or bookkeeper.

How to find a CPA in California: start with a credential check

For a California CPA or accounting firm, begin with the California Board of Accountancy lookup. It offers separate searches for California CPAs or California accounting firms, out-of-state CPAs and out-of-state accounting firms. ^[1] A California CPA has a CBA license, while a California accounting firm meets the board’s minimum registration requirements to provide public accounting services in California. ^[1]

Write down the exact name used in the search and whether the engagement is with an individual, a firm or both. If a candidate says they work from another state, ask which California services the firm expects to provide. The CBA says an out-of-state accounting firm must first register with it for certain services for a California-headquartered entity. ^[1] A no-result out-of-state CPA search also needs context: the board says that result does not mean the person lacks authority to practice in California. ^[1]

For federal-return work, the IRS directory is a second check. It includes certain preparers with an active PTIN, including CPAs, enrolled agents, attorneys and Annual Filing Season Program participants. ^[2] The directory is updated weekly, though a new or revised entry can take up to four weeks to appear. ^[2] Its limits matter: noncredentialed preparers outside AFSP are absent, and some paid preparers who would otherwise appear choose not to be listed. ^[2]

To check a paid California preparer who is not a CPA, enrolled agent or attorney, look the preparer up with CTEC, the council that registers preparers under California's Tax Preparation Act; by law CTEC must post disciplinary actions against registrants and a notice of any paid claim on a preparer's bond, and a preparer must give each customer the CTEC website address in writing before starting work (B&P Code ss. 22250.1, 22252 and 22253, as in force for 2026). ^[6]

Use this six-point comparison sheet

Give each candidate a score from 1 to 5 and add a note. The number is only a way to make the conversation concrete.

Ask every firm the same questions. A dental or medical practice can bring production reports, payroll records and ownership changes. A law firm can bring trust-account questions, partner information and prior returns. Real estate investors and agents can bring closing statements, entity records and rental summaries. Established contractors can bring job-cost reports, payroll records and current contracts. These are practical starting records for the discussion. The firm can then provide its own request list.

Compare the people who will do the work

Ask who prepares the return, who reviews the finished work and who answers a notice. Then ask whether the same people handle the work when volume rises. Put names beside those roles on your worksheet. This keeps a polished introduction separate from the day-to-day working relationship.

The PTIN question is worth asking directly for federal returns. The IRS says anyone who prepares or assists in preparing federal tax returns for compensation must have a valid 2027 PTIN before preparing returns; enrolled agents also need a valid PTIN. ^[3] Ask the candidate to explain the role each person on the engagement will have. That conversation is more useful than assuming a job title tells the whole story.

Read the records and authority terms before you sign

Ask what copy of the completed return you will receive, when you will receive it and where it will be stored. California’s FTB penalty reference lists a $50 penalty per failure, capped at $25,000 in a calendar year, for a preparer’s failure to furnish a completed return or claim copy; it also lists reasonable cause and not willful neglect. ^[5] The same reference lists a failure to retain a completed copy for three years or a client list, to retain an electronic filing declaration, and to make the return or list available for FTB inspection. ^[5] Keep your own secure copy as part of the closeout process.

Treat a power of attorney as a separate decision. An FTB POA can let a representative look at account information, talk to the FTB, send information and represent you. ^[4] For a business, the form is FTB 3520 BE. ^[4] An FTB POA generally lasts six years, and anyone listed on the declaration can revoke it. ^[4] Ask which years, accounts and actions the firm wants covered, then retain the signed version with your tax records.

Before you hire

• Before preparing a 2027 federal return: a paid preparer needs a valid 2027 PTIN. ^[3]

Questions that separate two similar firms

Ask for a plain-language outline of the first year’s work. Ask what records the firm needs before it starts, what will trigger a question, and what happens when a notice arrives. Ask how a change in ownership, a new entity or a large transaction gets surfaced. Then ask the same questions of the other candidate and compare the written answers.

Online reviews can point to questions, but they do not replace a credential search, a clear scope or a conversation about the people doing the work. Use a review to notice patterns in responsiveness or organization, then test those themes in your own discussion.
