How Long Does It Take to Become a CPA?

This is the most honest answer available, because the two bodies that actually govern the credential — NASBA and the AICPA — describe the requirements, not a timeline. A CPA license is issued by a state board of accountancy once a candidate has met educational standards, passed the Uniform CPA Exam, and completed a specific amount of accounting experience. Each of those three pieces has its own pace, and they don't have to happen in a fixed sequence in every state. Someone who already holds a 150-hour accounting degree and works in public accounting full time will move through this far faster than someone who needs extra coursework before they're even eligible to sit the exam. If you see a specific figure like '12-18 months' or '7 years' elsewhere, treat it as one source's estimate of a typical case, not an official rule — check your CPA eligibility against your target state board directly.

What NASBA does confirm is the structure candidates are preparing for: passing the Uniform CPA Examination is one of the two central requirements for becoming a CPA, alongside meeting state licensing rules. Beyond that structural fact, neither NASBA nor the AICPA states how long preparation typically takes, because study pace depends on a candidate's existing accounting background, how many hours a day they can dedicate, and which of the CPA exam sections they find hardest. A working professional studying part-time will need considerably longer than a recent graduate studying full time. Rather than relying on a generic figure, candidates are better served by building a personal schedule against their own availability — a study planner can help map exam sections against a realistic weekly study load instead of assuming a one-size-fits-all timeline.

A Certified Public Accountant is not a single national qualification — it is a license granted individually by each US state or territory's board of accountancy, once a candidate has met that board's specific education standards, passed the Uniform CPA Exam, and completed the required work experience (NASBA). Because licensing sits with the state, not a single national body, the 'how long' question really has as many answers as there are states. Two candidates who pass the exam on the same day, in different states, can end up with very different total timelines depending on their state's experience requirement and how their prior education is evaluated.

It helps to think of 'completing CPA' as three separate clocks rather than one. The education clock covers meeting your state's semester-hour and coursework rules before you're eligible to sit the exam. The exam clock covers passing all four sections of the Uniform CPA Exam. The experience clock covers accumulating the accounting work experience your state requires for licensure, which for many states means at least one year, though the type and amount required varies (NASBA). These clocks can run partly in parallel — many candidates work in accounting roles while sitting exam sections — which is one reason a single combined figure is misleading rather than useful.

The AICPA's state-requirements resource confirms that each US state and territory has its own board of accountancy setting rules for education, exam eligibility, work experience, ethics and residency (AICPA/ThisWayToCPA). This matters for timeline specifically because states also enforce requirements around age and residency in addition to education (NASBA), and these combine differently in every jurisdiction. A useful practical fact: where you sit the exam doesn't have to match where you eventually get licensed, since scores transfer between states — so a candidate isn't locked into one state's rules simply because that's where they tested.

Compensation for CPAs depends on factors like role, industry, seniority, location and firm size, none of which are addressed in NASBA's or the AICPA's licensure guidance. If salary is a factor in your decision to pursue the credential, it deserves its own research rather than a guess bundled into a timeline article — see the CPA salary page for a grounded look at what actually drives CPA compensation.

'Fully licensed' specifically means the state board has confirmed all three requirements are met, not just that the exam is passed. NASBA is explicit that after passing all four sections, candidates must still complete other requirements — education and work experience — before the license is issued, and these continue to vary state by state (NASBA). This is the step candidates most often underestimate: passing the exam feels like the finish line, but it is a milestone inside the process, not the end of it. Individuals who live and work in the US are required to be licensed in the state where they live and practice, so it's worth confirming that state's exact experience and education rules early, not after passing the exam.

NASBA confirms that candidates seeking to qualify as CPAs are required to pass the Uniform CPA Examination (NASBA), which consists of four sections, but does not publish a typical or required completion window across all sources reviewed here. Many candidates space sections out over several testing windows rather than sitting all four in one block, often to manage study time around a job. Anyone planning their own pace should check current section-scheduling rules directly, since testing windows and any rolling eligibility periods are set and updated by NASBA and state boards rather than fixed indefinitely. It's also worth deciding which section to sit first strategically, since section order affects momentum and how content overlaps.

NASBA states plainly that education requirements to sit for the CPA Exam differ by state, with some states requiring 150 total semester hours and others requiring less (NASBA). A standard US bachelor's degree is typically around 120 semester hours, so candidates in a 150-hour state often need additional coursework — sometimes a master's degree, sometimes extra undergraduate credits — before they're even eligible to test. This is exactly why 'CPA duration' can't be answered with one number: a candidate already holding 150 qualifying hours can move to the exam stage immediately, while a candidate short of that threshold has an extra education phase to complete first. Confirm your own state's exact hour and coursework rules on your CPA eligibility page before assuming either scenario applies to you.

NASBA states that many states require at least one year of public accounting work experience to qualify for a CPA license, while others accept different types of work experience such as teaching, self-employment and part-time employment (NASBA). Some states go further and specify a certain amount of auditing experience specifically, rather than accepting general accounting work. This is a major source of timeline variation that's easy to overlook: two candidates who pass the exam simultaneously could still be years apart from licensure if one needs a specific, harder-to-source type of experience and the other doesn't. Candidates who are also weighing whether the CPA is worth it while already working should factor in whether their current job actually counts toward their target state's experience rule.
