A CPA license is a professional credential that allows you to offer accounting and tax services to the public

CPA stands for Certified Public Accountant. It is a license issued by your state that certifies you have met specific education, testing, and experience requirements in accounting and taxation. Unlike a driver's license, which permits you to operate a vehicle, a CPA license permits you to practice public accounting — meaning you can sign off on financial statements, prepare tax returns for clients, and offer accounting information as a professional service.

The license is state-based, not federal. Each state's board of accountancy sets its own rules, though most states follow similar standards set by the American Institute of Certified Public Accountants (AICPA). This means a CPA licensed in one state can often transfer to another, but the process varies by state.

The credential is not required to work in accounting — many accountants, bookkeepers, and tax preparers do not hold a CPA license. But certain work, like auditing public companies or signing tax returns as a preparer, often requires it. For many clients, the CPA designation signals that you have met a uniform standard of knowledge and ethics.

Key Takeaways

  • A CPA license is a state-issued credential that allows you to offer accounting and tax services to the public under the title "Certified Public Accountant."
  • You must pass the Uniform CPA Examination, meet education requirements (usually a bachelor's degree with specific accounting and business courses), and complete work experience under a licensed CPA.
  • Each state's board of accountancy sets its own rules, so requirements and timelines vary by location.
  • The license must be renewed periodically, typically every one to three years, and renewal requires continuing education hours.
  • You do not need a CPA license to work in accounting, but certain roles — like auditing public companies or signing client tax returns — often require it.

The Three Main Requirements to Earn a CPA License

Every state requires three things before you can sit for the CPA exam: education, the exam itself, and work experience. The order and timing vary slightly by state, but all three must be completed.

Education typically means a bachelor's degree from an accredited college or university, with a minimum number of accounting and business courses. Most states require 150 semester hours of college coursework — that is one and a half times a typical four-year degree. The courses must include financial accounting, managerial accounting, auditing, taxation, and business law. Some states allow you to sit for the exam before finishing all coursework, but you cannot receive your license until you have completed the full education requirement.

The Uniform CPA Examination is a four-part test administered by the AICPA. The sections are Auditing and Attestation, Financial Accounting and Reporting, Regulation, and Business Environment and Concepts. You can take the sections in any order and retake any section you do not pass. Most states require you to pass all four sections within a rolling window — typically five years from your first passing score. The exam is computer-based and offered year-round at testing centers.

Work experience requirements vary widely. Most states require one to two years of accounting work under the supervision of a licensed CPA. Some states allow you to count certain academic or internship hours toward this requirement. A few states have no experience requirement at all, though this is uncommon. You must document your experience and have your supervisor sign off on it.

How State Boards Set Different Rules

Because each state issues its own licenses, the rules are not identical across the country. The National Association of State Boards of Accountancy (NASBA) coordinates standards, but states retain the power to set their own thresholds.

For example, some states allow you to sit for the CPA exam after completing 120 semester hours of coursework, while others require the full 150. Some states let you count internship hours toward the work experience requirement; others do not. A few states require you to pass the exam before you can begin your required work experience, while most allow you to work and study simultaneously.

The state where you first obtain your license is called your home state. If you later move or want to practice in another state, you can request reciprocity or reciprocal licensure — meaning the new state recognizes your existing license without requiring you to retake the exam or repeat coursework. However, the new state may impose additional requirements, such as a higher continuing education threshold or proof that you have been actively practicing.

The CPA Exam: Structure, Cost, and Timing

The Uniform CPA Examination is administered by the AICPA through Prometric, a testing company. You register through your state board of accountancy, not directly with the AICPA. Registration fees and exam fees vary by state but typically total $200 to $300 per section, or $800 to $1,200 for all four sections.

Each section takes four hours and covers a different area of accounting practice. You can space the sections out over months or years, as long as you pass all four within your state's rolling window. Most candidates take the sections in the order recommended by the AICPA, but you are not required to. Many people study for and take one or two sections at a time while working or in school.

The exam is offered year-round at testing centers in most cities. You schedule your test date through your state board's portal. Most people spend three to six months studying for each section, though this varies based on your background and study habits. Many candidates use review courses — either self-paced online programs or instructor-led classes — which cost $500 to $3,000 depending on the provider.

Maintaining Your License After You Earn It

Once you receive your CPA license, you must renew it periodically to keep it active. Renewal cycles vary by state — some require renewal every year, others every two or three years. Renewal fees typically range from $100 to $400 per cycle.

The main renewal requirement is continuing professional education (CPE). Most states require 40 CPE hours per year, though some require as few as 20 or as many as 80. CPE hours must come from courses or training related to accounting, taxation, auditing, or business topics. You can earn them through online courses, in-person seminars, university classes, or webinars offered by professional organizations.

If you do not renew your license on time or fail to meet CPE requirements, your license becomes inactive or lapsed. You can usually restore it by paying back fees and completing any missing CPE hours, but the process takes time. Some states allow you to place your license on inactive status if you are not currently practicing, which may have lower renewal fees or CPE requirements.

CPA License Versus Other Accounting Credentials

The CPA license is the most widely recognized accounting credential in the United States, but it is not the only one. Understanding the difference helps you decide whether the CPA path is right for you.

A bookkeeper or accounting clerk does not need any license. These roles involve recording transactions, reconciling accounts, and preparing basic financial records. Many bookkeepers take voluntary certifications like the Certified Bookkeeper (CB) credential, but it is not required.

An Enrolled Agent (EA) is a tax specialist licensed by the Internal Revenue Service. Enrolled Agents can represent clients before the IRS and prepare tax returns, but they do not need to meet the same education or experience requirements as a CPA. The EA credential is easier to obtain and costs less, but it is narrower in scope — it covers tax work primarily, not auditing or general accounting.

A Certified Management Accountant (CMA) is a credential for accountants who work inside companies rather than in public practice. CMAs focus on management accounting, cost analysis, and internal reporting. The CMA requires a bachelor's degree, two years of work experience, and passing a two-part exam, but it does not allow you to sign client tax returns or audit public companies.

When You Need a CPA License and When You Do Not

You need a CPA license if you want to offer certain services to the public under the title "Certified Public Accountant." Specifically, you must be licensed to sign off on audits of public companies, sign tax returns as a preparer, and offer accounting services as a professional firm.

You do not need a CPA license to prepare tax returns for yourself or family members, to work as an accountant inside a company, to do bookkeeping, or to offer general financial information. Many accountants work their entire careers without a CPA license. The license becomes valuable when you want to start your own practice, sign client tax returns, or work for a firm that requires it.

Some employers — particularly large accounting firms, government agencies, and companies with complex accounting needs — prefer or require a CPA license for certain positions. If you are early in your accounting career, checking whether your target employers value the credential can help you decide whether to pursue it.

Frequently Asked Questions

How long does it take to get a CPA license?

Most people take two to four years from the time they start studying to the time they receive their license. This includes time to complete education requirements, study for and pass the four-part exam, and accumulate work experience. The timeline depends on whether you already have a bachelor's degree, how quickly you pass the exam sections, and your state's work experience requirement.

Can I use the CPA title if I have not finished all the requirements?

No. You cannot call yourself a CPA or use the CPA designation until your state board has issued your license. Using the title before you are licensed is illegal in most states and can result in fines or legal action. You can say you are "CPA candidate" or "pursuing the CPA" while you are working toward it.

Do I have to renew my CPA license every year?

Renewal frequency depends on your state. Some states require annual renewal, while others renew every two or three years. Check your state board of accountancy website to find your specific renewal cycle and important date. Missing a renewal important date can result in your license becoming inactive.

Can I transfer my CPA license to another state?

Yes, through reciprocity. Most states recognize CPA licenses from other states without requiring you to retake the exam or repeat coursework. However, the new state may require you to pay a reciprocity fee, meet additional CPE requirements, or provide proof of active practice. Contact the state board where you want to practice to learn their specific process.

What happens if I fail a section of the CPA exam?

You can retake any section you do not pass. Most states allow unlimited retakes, though you must pass all four sections within a rolling window — usually five years from your first passing score. You pay the exam fee again for each retake. Many candidates retake one or two sections before passing all four.
