CPA: the US accounting license, its exam structure and requirements

The CPA — Certified Public Accountant — is the US license to sign audit opinions and, more broadly, the strongest signal in accounting, tax and financial reporting. The exam is written by the AICPA, administered with NASBA and the state boards, and each state licenses its own CPAs — which is why every path starts with 'pick your state'.

The exam after CPA Evolution

The exam's classic face was four equal sections — FAR, AUD, REG and BEC. Under the CPA Evolution model that took effect in 2024, BEC was retired and the structure became three core sections — AUD (audit and attestation), FAR (financial accounting and reporting) and REG (taxation and regulation) — plus one discipline section you choose: BAR (business analysis and reporting), ISC (information systems and controls) or TCP (tax compliance and planning). The core/discipline split lets you match the exam to your career instead of memorizing one more homogeneous section.

Requirements beyond the exam

Beyond the exam: most states require 150 semester hours of education (a US bachelor's is typically 120, so candidates add credits — a master's degree is the common route; a few states now pilot 120-plus-experience alternatives), one to two years of supervised experience signed off by a licensed CPA, and in several states a separate ethics exam. Jurisdiction rules differ on residency, so international candidates usually run a credential evaluation of their foreign transcripts first and pick the state whose requirements their education already fits.

What the CPA means for an Iranian accountant

For an Iranian accountant the CPA is primarily an emigration and international-firm credential: Big Four and large regional firms treat it as the audit license of record, and US-oriented careers (reporting, controllership, tax) run through it. Its lens is US GAAP and US tax — if your destination is the UK, the Gulf or a Commonwealth market, weigh the ACCA alongside it: broader international footprint, no state-board maze, but less US-tax depth. The honest comparison is destination-first, credential-second.

How FinScope helps

FAR's hidden engine is time value plus depreciation, and both are free to practice. Take the engine-verified asset: cost 10,000, salvage 1,000, life 5 years → straight-line gives 1,800 per year; sum-of-years-digits opens at 3,000; double-declining opens at 4,000. Same totals, different timing — which is precisely what FAR asks you to reason about. Reproduce all three on the depreciation worksheet, then move to the TVM tab for lease and bond schedules.

• FAR: present value of lease payments, pension obligations and bond amortization schedules.
• REG: after-tax proceeds, installment sales and depreciation-recapture math.
• BAR: impairment tests and discounted cash-flow measurement of reporting units.
• Everywhere: effective-interest amortization of bonds issued at a discount or premium.

1. Run a credential evaluation of your transcripts (essential for international candidates).
2. Pick the state board whose credit-hour and experience rules you can actually satisfy.
3. Apply, receive your Notice to Schedule, and book FAR or AUD first — they take the longest.
4. Study 300–500 total hours across the sections; a rolling credit window applies from your first pass (historically 18 months, several jurisdictions now longer — verify current policy).
5. Complete supervised experience, pass any state ethics exam, and file for the license.

Once licensed, keep the numeric edge: the FinScope Learning Center documents the same depreciation, bond and TVM formulas the exam expects, and the Fin Tools suite covers the rest of the day-to-day math.
