US CPA Complete Roadmap — Exam Structure, Subjects, and Passing Strategy

What Is a US CPA?

The Certified Public Accountant (CPA) is the premier accounting credential in the United States, administered by the American Institute of CPAs (AICPA) and regulated by individual state boards of accountancy. The CPA is the only credential authorized to issue audit opinions on publicly filed financial statements.

Governing body: AICPA (exam) + NASBA (National Association of State Boards of Accountancy)
Annual new CPA candidates: ~74,000 exam sections passed per year
Exclusive work: Signing audit reports for SEC registrants and other regulated entities; CPA firms sign attest engagements

The CPA’s defining feature is the attest function: only a licensed CPA can issue audit opinions on financial statements filed with the SEC or required by regulators. This represents an exclusive, legally protected scope of work.

Eligibility Requirements

The 150-Hour Rule

Most states require:

150 semester hours of college education (typically 30 hours beyond a bachelor’s degree)
A minimum of 24 hours in accounting subjects
A minimum of 24 hours in business subjects

Methods to satisfy the 150-hour requirement:

Master’s in Accounting (MAcc) or MBA with accounting concentration
150-hour undergraduate programs (5-year CPA track)
Post-baccalaureate accounting certificate programs
Community college courses to complete remaining hours

State requirements vary — some states allow exam sitting at 120 hours and defer the 150-hour requirement to licensure. Always verify with your target state’s Board of Accountancy.

Exam Structure (CPA Evolution — 2024 Format)

The AICPA introduced the CPA Evolution framework in 2024, restructuring the exam into:

Core Sections (All Candidates Must Pass)

Section	Acronym	Topics	Exam Length
Auditing and Attestation	AUD	Audit standards, ethics, evidence, reporting	4 hours
Financial Accounting and Reporting	FAR	US GAAP, IFRS, government accounting, nonprofits	4 hours
Regulation	REG	Federal tax (individual + business), business law, ethics	4 hours
Business Analysis and Reporting	BAR	Analytics, financial reporting, variance analysis	4 hours

Discipline Sections (Choose One)

Section	Acronym	Focus
Business Analysis and Reporting	BAR	Advanced analytics, reporting, financial statement analysis
Information Systems and Controls	ISC	IT audit, cybersecurity, data analytics
Tax Compliance and Planning	TCP	Advanced individual and entity taxation, planning

Note: Under CPA Evolution, candidates choose one Discipline section based on their intended specialization.

Passing score: 75 on a 0–99 scale (not a percentage — a scaled score).

Time limit: Pass all four sections within an 18-month rolling window (clock starts when the first section is passed).

Subject Areas and Study Strategy

Financial Accounting and Reporting (FAR) — Highest Volume

The most content-heavy section. Covers the full spectrum of US GAAP and selected IFRS topics.

Core topics:

Revenue recognition (ASC 606)
Leases (ASC 842)
Business combinations (ASC 805)
Consolidations and equity method investments
Government accounting (GASB standards)
Nonprofit accounting

Study strategy:

FAR has the most content; allocate the most study time (120–150 hours recommended)
Focus on understanding the logic of standards, not just memorizing rules
Practice multi-step simulations (the task-based simulation format is critical)

Auditing and Attestation (AUD)

Covers audit standards (US GAAS / PCAOB), internal control, attestation, and compilation/review engagements.

Core topics:

Risk assessment (inherent, control, detection risk)
Internal control over financial reporting (ICFR)
Evidence gathering and sampling
Audit opinions and reporting
Professional ethics (independence, objectivity)

Study strategy:

Heavy on professional judgment scenarios — think like an auditor
Ethics and independence rules are frequently tested and must be memorized precisely
The PCAOB rules are especially important for candidates heading to public company auditing

Regulation (REG)

Two domains: federal taxation and business law.

Taxation topics:

Individual income tax (Form 1040 — wages, capital gains, deductions, credits)
Business entity taxation (C corps, S corps, partnerships, LLCs)
Estate and gift tax basics
Tax procedures (IRS audit, penalties, statutes of limitations)

Business law topics:

Contracts (formation, breach, remedies)
Agency law
Securities regulation (basics of SEC reporting)
Debtor-creditor relationships (bankruptcy basics)

Study strategy:

REG is calculation-heavy — practice problems extensively
Tax law changes frequently; use an updated prep course
Business law topics are mostly conceptual and testable through multiple-choice patterns

Business Analysis and Reporting (BAR) — Core Section

New under CPA Evolution. Tests data-driven financial analysis.

Core topics:

Variance analysis (flexible budgets, standard costing)
Cost-volume-profit analysis
Financial ratios and benchmarking
Data analytics for financial reporting (Excel, Power BI concepts)
Forecasting and projection methodologies

Pass Rates and Exam Statistics

Section	Average Pass Rate
AUD	~48–52%
FAR	~43–47%
REG	~55–60%
BAR	~50–55%

The CPA exam is one of the most rigorous professional licensing exams in the US. Most candidates require 300–400 total study hours across all sections.

The 18-month window means candidates must manage both pace (don’t wait too long between sections) and depth (don’t rush and fail, resetting the clock).

Study Timeline by Background

Accounting Major (150-hour path)

2–3 years from the start of a focused study plan.

Year 1: Complete qualifying education through a MAcc or extra coursework
Year 1–2: Pass all four sections (suggested order: FAR → AUD → REG → BAR)
Year 2–3: Accumulate 1–2 years of relevant experience for full CPA licensure

Non-Accounting Major

3–5 years is realistic.

First: Complete 150 hours of education including accounting prerequisites
Then: Begin structured CPA exam prep (commercial review courses: Becker, Roger CPA, Wiley CPAexcel)
Allow additional time for unfamiliar content areas

Fast-Track Strategy

Candidates who already have a MAcc or 150 hours can attempt the exam within 6–12 months of focused study
Passing all four sections in one year requires approximately 10–12 study hours per week
Taking AUD first is sometimes recommended to build audit logic before FAR’s volume

Career Paths After CPA Licensure

Big 4 Public Accounting (Deloitte, PwC, EY, KPMG)

The standard entry point. New associates typically start in:

Audit: Assurance engagements, ICFR testing, public company audits under PCAOB
Tax: Federal and state compliance, international tax structuring
Advisory / Consulting: Deal advisory, valuation, risk, technology consulting

After 3–5 years, most Big 4 alumni either make manager/senior manager or move to industry.

Mid-Size and Regional CPA Firms

Offer faster path to partnership, greater client variety, and better work-life balance than Big 4. Strong demand in regional markets.

Corporate Finance and Accounting (Industry)

Controller, Director of Finance, or VP of Finance at public or private companies. The CPA is the gold standard credential for CFO and controller track roles.

Financial Institutions

Banks, insurance companies, and investment managers hire CPAs for internal audit, financial reporting, regulatory capital management, and risk modeling.

Government and Nonprofit

The IRS, GAO (Government Accountability Office), SEC, and FDIC are significant employers of CPAs. State governments and large nonprofits also rely heavily on CPA-credentialed staff.

CPA vs. Enrolled Agent (EA) vs. CFA

Credential	Focus	Exam	Best For
CPA (AICPA)	Audit + Tax + Advisory	4-section exam	Broad accounting/audit career
Enrolled Agent (IRS)	Federal tax only	3-part EA exam	Tax specialists, independent tax practice
CFA (CFA Institute)	Investment analysis	3-level exam	Portfolio management, investment banking

For tax specialization without auditing: the Enrolled Agent (EA) credential (granted by the IRS) is an accessible alternative with no degree requirement. For broad accounting + audit + tax: the CPA is essential.

Economics Fundamentals: Background for understanding macroeconomic context in FAR and REG
Business Fundamentals: Management and business law concepts that underlie the REG business law section
