How to Hire an Accountant: Credentials, Fees, and Engagement

To hire an accountant, decide what work you actually need done, shortlist credentialed professionals who do that work, verify their license through an official database, and sign a written engagement letter before any work begins. CPA hourly rates generally run from $200 to $500, so the cost of hiring the wrong level of expertise is real. The steps below walk through each decision in the order you’ll face it.

Start With the Work, Not the Title

The job you need done determines the credential you should hire. Accounting work falls into a handful of distinct categories, and the right professional for one is often the wrong professional for another.

  • Tax preparation — calculating liabilities and filing annual returns. Personal returns can be handled by an enrolled agent, a CPA, or an Annual Filing Season Program participant. Complex business returns or multi-state filings typically call for a CPA or EA with relevant experience.
  • Tax planning and credits — proactive strategies to reduce future liability, including specialized work like Research and Development credit studies. Needs a CPA or EA with technical expertise in the specific area of tax law.
  • Financial statement auditing — an independent review verifying the accuracy of a company’s financial reports. Only CPAs can perform certified audits.
  • Bookkeeping and payroll — day-to-day tracking of income, expenses, and withholdings. A bookkeeper can handle routine tasks; a CPA adds oversight and strategic guidance.
  • Business consulting — entity structure, operational efficiency, growth planning. CPAs with advisory experience are the typical choice.
  • Forensic accounting — investigating financial discrepancies or fraud, often for legal proceedings. A specialized CPA niche.
  • IRS representation — audits, disputes, or collection matters. Only CPAs, attorneys, and enrolled agents have unlimited representation rights.

If your needs span multiple categories, say monthly bookkeeping plus year-end tax preparation, identify that upfront so candidates can quote accurately for the full scope.

Match the Credential to the Service

Four tiers of professional handle most private-client accounting work, and the differences matter when something goes wrong with the IRS.

Certified Public Accountants

A CPA holds the broadest scope of practice. Licensure is governed by state boards following the Uniform Accountancy Act, a model framework published jointly by the AICPA and the National Association of State Boards of Accountancy.1NASBA. New CPA Licensure Pathways and CPA Mobility CPAs can audit financial statements, prepare tax returns, provide consulting, and represent you before the IRS with unlimited practice rights.2Internal Revenue Service. Treasury Department Circular No. 230

Enrolled Agents

An enrolled agent is a tax specialist authorized by the U.S. Department of the Treasury. To earn the designation, a person passes a three-part Special Enrollment Examination covering individual taxes, business taxes, and representation, or qualifies through prior IRS employment.3Internal Revenue Service. Become an Enrolled Agent Like CPAs and attorneys, EAs have unlimited practice rights before the IRS, meaning they can handle any type of tax matter in any IRS office on your behalf.4Internal Revenue Service.

Annual Filing Season Program Participants

Tax preparers who aren’t CPAs, attorneys, or EAs can voluntarily complete the IRS Annual Filing Season Program. Participants receive limited representation rights: they can only represent clients whose returns they personally prepared and signed, and only before revenue agents and customer service representatives. They cannot handle collection or appeals matters, and they cannot represent clients whose returns they did not prepare.5IRS. Annual Filing Season Program – Record of Completion

Bookkeepers and Non-Certified Preparers

Anyone with a Preparer Tax Identification Number can legally prepare a federal tax return for a client.6IRS. Directory of Federal Tax Return Preparers with Credentials and Select Qualifications But bookkeepers and non-certified accountants cannot represent you before the IRS at all, and they cannot perform certified audits. If your needs extend beyond basic record-keeping and return preparation, you need a credentialed professional.

Build a Shortlist of Candidates

Aim for at least two or three candidates so you can compare qualifications, communication styles, and fees before committing. A few places to look:

  • The IRS Directory of Federal Tax Return Preparers is a free, searchable tool listing preparers who hold an active PTIN plus a recognized credential (CPA, EA, attorney) or AFSP completion. It is not a complete list of paid preparers; it only shows those with credentials or AFSP participation.7Internal Revenue Service. FAQs – Directory of Federal Tax Return Preparers with Credentials and Select Qualifications
  • State CPA society referral services maintain directories of member accountants, usually searchable by location and specialty.
  • Professional referrals from attorneys, bankers, and other business advisors who work with accountants regularly often surface someone who already handles situations like yours.

Verify the License Yourself

Titles are easy to claim. Licenses are easy to verify, and you should check every one.

CPA License Status

CPAverify, maintained by NASBA, is the only free national database of licensed CPAs available to the public. A single search by name returns current license information across all 53 boards of accountancy, and if a CPA is licensed in multiple states, all active licenses appear in one result. CPAverify shows current license status only; it does not display educational background, employment history, or past disciplinary actions.8NASBA. What is CPAVerify?

Disciplinary History

To check whether a CPA has faced sanctions, contact the state board of accountancy directly. Most state boards publish enforcement orders on their websites, organized by year, and some allow name searches. A CPA can hold an active license while having a disciplinary history you’d want to know about, so treat this as a separate step from CPAverify.

Enrolled Agents and Tax Preparers

The IRS Directory of Federal Tax Return Preparers confirms whether a tax professional holds an active EA credential, CPA license, or AFSP completion.6IRS. Directory of Federal Tax Return Preparers with Credentials and Select Qualifications Every person paid to prepare federal tax returns must have a valid PTIN.9Office of the Law Revision Counsel. 26 U.S. Code 6109 – Identifying Numbers Ask any candidate for their PTIN during your first conversation.

Firm Peer Review (for Audit Work)

If you’re hiring a CPA firm for audits, reviews, or compilations, check whether the firm has undergone peer review. The AICPA Peer Review Program maintains a public file where you can search a firm’s enrollment status and most recent peer review date.10AICPA. Public File Search – AICPA Peer Review A firm that performs audits but cannot point to a recent peer review deserves extra scrutiny.

Prepare Your Documents Before Interviewing

Walking in with your records lets each candidate give you an accurate assessment and quote. Walking in empty-handed produces vague estimates and wastes both sides’ time.

  • Federal and state tax returns for the previous three years.
  • Your most recent profit-and-loss statement and balance sheet.
  • A general ledger, so the accountant can gauge the volume and complexity of your bookkeeping.
  • Entity formation documents for a business — articles of incorporation, operating agreement, or partnership agreement.
  • Your Employer Identification Number or Social Security Number for administrative setup and filings.

Do not send tax returns or Social Security numbers through unencrypted email. Ask each candidate about their secure file-sharing method before transmitting anything. Most legitimate firms use encrypted client portals. If a firm asks you to email scanned returns as unprotected attachments, treat that as a warning sign.

What to Ask in the Interview

Credentials confirm the person is qualified. The interview tells you whether they’re the right fit. Focus on these areas:

  • Industry experience. A CPA who specializes in real estate partnerships handles very different issues than one who focuses on medical practices. Relevant experience means fewer learning curves at your expense.
  • Communication and availability. Ask how quickly routine questions get answered, whether communication runs through a portal or email, and how the firm handles urgent issues during tax season.
  • Technology and software. Confirm which accounting platforms the firm uses, whether they support cloud access, and whether their system is compatible with yours.
  • Fee structure. Ask how fees are calculated and what triggers additional charges. Get the estimate in writing.
  • Scope boundaries. Clarify what falls inside and outside the proposed engagement. If you expect payroll handling and the accountant expects only year-end filing, that gap needs to surface before you sign.

Walk away from any accountant who guarantees a specific refund amount before reviewing your records, pressures you to sign documents you haven’t read, or is reluctant to provide references.

Compare Fees on Equal Terms

Accounting fees vary with service type, experience, and location. Three fee models dominate.

  • Hourly billing is the traditional model. CPA hourly rates generally fall between $200 and $500, with highly specialized work (forensic accounting, large-firm audits) sometimes reaching higher. The model fits unpredictable or one-time engagements but makes costs hard to forecast.
  • Flat-rate or fixed-fee pricing sets a single price for a defined service, such as an annual return or monthly bookkeeping. You know the cost upfront, and the accountant absorbs the risk if the work takes longer than expected.
  • Value-based pricing ties the fee to the complexity and value of the work rather than hours spent. This has become more common as technology shortens routine tasks while the strategic value of advice remains high.

When comparing quotes, make sure you’re comparing the same scope. A lower fee covering only tax preparation is not cheaper than a higher fee that includes bookkeeping, payroll, and tax planning. Ask each candidate to itemize what the quote includes and what would trigger additional charges.

Get the Engagement Letter Right

Once you select a professional, formalize the relationship in a written engagement letter before any work begins. The letter is the contract. A well-drafted one covers:

  • Scope of services, described specifically. Vague language like “general accounting services” invites disputes later.
  • Deadlines and timing for deliverables, including tax filing dates and reporting periods.
  • Fee arrangement — rate or fixed price, payment schedule, and conditions that could change the cost (such as additional complexity discovered during the engagement).
  • Responsibilities of each party. What records you must provide and by when, and what the accountant will deliver.
  • Data handling and retention. How your records are stored, protected, and returned when the engagement ends.

Read the letter carefully. If the scope doesn’t match what you discussed, ask for revisions. Once signed, the letter governs the relationship, and verbal promises that didn’t make it in are difficult to enforce.

Give the IRS Authority Only If You Mean To

If your accountant will communicate with the IRS on your behalf, you have to grant that authority formally. There are two separate forms, and they do different things.

Form 2848, Power of Attorney, authorizes a representative to act on your behalf before the IRS. Once signed, your representative can inspect confidential tax information, sign agreements, respond to notices, and perform essentially any act you could perform regarding the tax matters described on the form.11Internal Revenue Service. Instructions for Form 2848 – Power of Attorney and Declaration of Representative The representative must be someone eligible to practice before the IRS: a CPA, attorney, enrolled agent, or other qualified individual listed in the form’s Declaration of Representative.12Internal Revenue Service. Form 2848 – Power of Attorney and Declaration of Representative

Form 8821, Tax Information Authorization, is the lighter option. It lets a designated person inspect and receive your confidential tax records but does not grant representation rights or the authority to act on your behalf.13Internal Revenue Service. Forms 2848 and 8821 for Tax-Advantaged Bonds Use 8821 when you want your accountant to pull IRS transcripts or review prior filings without full power of attorney.

Confirm Data Security Practices

Hiring an accountant means sharing Social Security numbers, bank details, income records, and business financials. Two legal protections sit behind that handoff, and both give you leverage to ask hard questions.

Tax preparation firms and accounting practices are classified as financial institutions under the Gramm-Leach-Bliley Act, which puts them under the FTC Safeguards Rule. The rule requires a written information security plan appropriate to the firm’s size, a written risk assessment, periodic review of who has access to client data, and encryption of client information in storage and in transit.14Federal Trade Commission. FTC Safeguards Rule: What Your Business Needs to Know

Federal law separately prohibits preparers from disclosing or using your tax return information for any purpose other than preparing your return without your written consent. Violation is a criminal offense carrying a fine of up to $1,000, up to one year in prison, or both.15Internal Revenue Service. IRC Section 7216 Questions and Answers

Ask the firm specifically how they handle your data: their client portal or encrypted file-sharing system, their retention policy, and who inside the firm will have access to your records. A credible answer should be ready without hesitation.

If You Need to Switch Later

You can leave an accountant at any point, but the mechanics matter so nothing falls through the cracks.

  • Review the engagement letter for termination provisions, notice periods, or outstanding fee obligations.
  • Request your original records in writing. Tax returns, receipts, and formation documents belong to you. Confirm the firm’s retention policy for work papers they created during the engagement.
  • Revoke any Form 2848 you signed by filing a new 2848 or a written revocation with the IRS. Your new accountant can help with this.
  • Send written notice of termination stating the effective date, the status of work in progress, and any outstanding balances. Use a method that proves receipt.
  • Start the transition well before any filing deadline. Your former accountant is not obligated to complete work after the relationship ends.
