Passing the CPA exam is only one of three requirements to become a licensed Certified Public Accountant — you also need to meet practical experience requirements and an education requirement. Most US states require 1–2 years (1,800–4,000 hours) of accounting experience under the direct supervision of a licensed CPA before granting a CPA license. The exact requirements vary by state — some require 1 year, others 2 years, and the type of qualifying experience differs. This guide covers practical experience hours by state, supervision requirements, what types of work qualify, and how to document and verify your experience for CPA licensure.
The practical experience requirement for CPA licensure is set by your state board of accountancy — not the AICPA. This means requirements differ across the 55 US jurisdictions (50 states + DC, Guam, Puerto Rico, US Virgin Islands, and the Northern Mariana Islands). Most states follow one of two models:
1-year (1,800+ hours) model: States like California, Texas, Florida, and New York require 1 year of qualifying experience. Some of these states require the experience to be in 'public accounting' (at a CPA firm), while others accept experience in industry, government, or academia.
2-year (2,000–4,000 hours) model: Some states require 2 full years of qualifying experience. The exact hour requirement depends on the state's definition (40-hour weeks for 1–2 years = 2,080–4,160 hours).
Key components required by most states:
The following are current requirements for major states. Always verify directly with your state board of accountancy — requirements are updated periodically.
California: 1 year (500 hours of attest experience required; total 12 months full-time or equivalent part-time). Must be under a CPA who is licensed in California or another US state. No requirement that the experience be at a public accounting firm.
Texas: 1 year under a licensed CPA — 2,000 hours total. Experience must be verified by a licensed CPA. Can be in public accounting, industry, government, or academia. Texas requires the CPA supervisor to attest that the work required the use of accounting, attest, compilation, management advisory, financial advisory, tax, or consulting skills.
New York: 1 year (1 year of full-time, 40 hours/week employment in public accounting, government, industry, or academia), under a licensed CPA. The experience must include accounting skills — purely administrative or clerical work does not qualify.
Florida: 1 year of experience in accounting under the supervision of a licensed CPA. Experience can be in public accounting, private industry, government, or academia.
Illinois: 1 year of full-time employment (52 weeks, not counting vacation) under the supervision of a licensed CPA. Part-time experience counts proportionally.
Colorado, Virginia, Michigan: 1 year, similar to the above states with qualifying experience definitions.
North Dakota, Rhode Island, Virgin Islands: 2 years of experience required — verify current requirements with those state boards.
Most states accept experience in any of the following areas, as long as it's performed under CPA supervision:
What typically does NOT qualify:
Experience documentation is submitted to your state board when you apply for your CPA license (after passing all 4 CPA exam sections and meeting the education requirement).
