CPA stands for Certified Public Accountant, a professional license granted by state boards of accountancy to individuals who meet specific education, examination, and experience requirements. It’s the highest standard credential in the accounting profession, and it comes with legal privileges that unlicensed accountants simply don’t have. If you’re trying to understand what separates a CPA from a regular accountant, or whether you need one, here’s what actually matters.
What a CPA Can Do That Other Accountants Can’t
The CPA license isn’t just a title. It unlocks specific legal authorities that no other accounting credential provides.
CPAs hold unlimited representation rights before the IRS. That means they can represent you in audits, appeals, and collections matters regardless of complexity. A tax preparer who isn’t a CPA, enrolled agent, or attorney can only represent you on returns they personally prepared and signed, and only in limited interactions with revenue agents and customer service reps. They can’t advocate for you in appeals or collections.
Only CPAs registered with the Public Company Accounting Oversight Board (PCAOB) can audit publicly traded companies. When a private company wants to go public, it needs at least two years of audited financial statements that meet PCAOB standards before filing with the SEC. A non-CPA accountant can run internal audits for a company’s own use, but they can’t provide the independent audit opinion that regulators and investors require.
CPAs can also sign what are called attestation reports: reviews, compilations, and agreed-upon procedures engagements. These are formal reports that provide assurance on financial information to third parties like banks, investors, or business partners. State accountancy boards restrict these services exclusively to licensed CPAs.
There’s even a limited communication privilege. Tax advice a CPA gives you in civil tax matters before the IRS carries a degree of confidentiality protection, though it doesn’t reach the level of attorney-client privilege. It doesn’t apply in criminal tax cases, state tax matters, or to tax return preparation itself. Communications with unlicensed accountants get no federal privilege protection at all.
How Someone Becomes a CPA
Earning a CPA license requires clearing three hurdles: education, examination, and experience.
On the education side, nearly every state requires 150 semester hours of college coursework at the undergraduate or graduate level. That’s 30 hours more than a typical four-year bachelor’s degree, which is why many CPA candidates earn a master’s degree or complete additional undergraduate courses. Some states are exploring alternative pathways that would allow candidates to qualify with 120 credit hours if they have additional work experience or continuing education, but the 150-hour rule remains the standard in most jurisdictions.
The Uniform CPA Examination, administered by the AICPA, consists of four sections, each lasting four hours. Three are core sections that every candidate must pass: Auditing and Attestation (AUD), Financial Accounting and Reporting (FAR), and Taxation and Regulation (REG). The fourth is a discipline section where candidates choose one of three specializations: Business Analysis and Reporting (BAR), Information Systems and Control (ISC), or Tax Compliance and Planning (TCP). The pass rate for individual sections typically hovers around 50%, making it one of the more difficult professional exams.
Most states also require one to two years of supervised work experience under a licensed CPA before granting the full license. The specifics vary by state, but the intent is the same: candidates need real-world practice before they’re entrusted with the responsibilities the license carries.
What CPAs Actually Do Day to Day
CPAs work across a wide range of services, not just tax preparation. For individuals, the most common service is preparing and filing tax returns, along with tax planning to reduce future liability. For small businesses, CPAs frequently handle business formation guidance, bookkeeping, payroll, financial statement preparation, auditing, and strategic advising.
Many CPAs specialize. Some focus entirely on tax work, others on forensic accounting or fraud investigation, and others on audit and assurance services for mid-size or large companies. Corporate CPAs often work as controllers, CFOs, or internal audit directors. Government agencies, nonprofits, and law enforcement also employ CPAs for financial oversight roles.
What CPA Services Cost
CPAs use several pricing models: hourly rates, flat fees per project, monthly retainers, or occasionally a percentage of a client’s revenue. The most common structure for individual clients is a flat fee for a defined task like tax preparation.
Hourly rates average around $175 but range widely from $60 to over $400 depending on the CPA’s location, specialization, and experience. In major metropolitan areas, rates of $500 per hour or more aren’t unusual for highly specialized work.
For specific services, expect to pay roughly $150 to $350 for individual tax preparation, $200 to $400 for bookkeeping services, and $250 to $500 for preparing financial statements. Complex business returns, audit work, or tax planning engagements will cost more. If you’re a small business owner, many CPAs offer bundled monthly packages that cover bookkeeping, payroll, and tax prep together.
Ethical Standards CPAs Must Follow
CPAs are bound by a formal code of professional conduct built on five principles: integrity, objectivity, professional competence, confidentiality, and professional behavior. These aren’t suggestions. State boards of accountancy enforce them, and violations can result in suspension or revocation of the license.
In practical terms, this means a CPA is obligated to be honest with you even when the truth is inconvenient, to avoid conflicts of interest, to maintain confidentiality over your financial information, and to stay current on tax law and accounting standards through mandatory continuing education. Most states require 40 hours of continuing professional education per year to keep the license active.
This accountability is one of the key reasons lenders, courts, and government agencies treat CPA-prepared documents as more credible than those prepared by unlicensed accountants. The license puts the CPA’s career on the line for the quality and accuracy of their work.
When You Actually Need a CPA
Not every financial task requires a CPA. If you have a straightforward W-2 tax return with no investments, rental properties, or self-employment income, tax software or a basic tax preparer may be perfectly adequate.
A CPA becomes valuable when your financial life gets more complex. You’d want one if you’re self-employed or own a business, have significant investment income, are going through a major life event like selling a home or inheriting assets, need audited financial statements for a loan or investor, or face an IRS audit or collections issue. The combination of technical expertise, legal authority, and professional accountability makes a CPA the right choice when accuracy and credibility matter most.
