Uniform CPA Examination — Taxation and Regulation (REG)
The CPA Core section on federal taxation, tax practice ethics and business law.
About the exam
Taxation and Regulation (REG) is one of the three Core sections every CPA candidate must pass. It covers ethics and federal tax procedure, business law, and federal taxation of property transactions, individuals and entities — what a newly licensed CPA needs to prepare returns and advise clients correctly.
The section runs 4 hours in five testlets: two testlets of multiple-choice questions (72 in all) followed by 8 task-based simulations such as tax form completion, numeric entry and research. Multiple choice and simulations each count for half your score. One Big Beautiful Bill Act (OBBBA) provisions effective in 2024–2025 have been testable since July 1, 2026, and unless a question says otherwise, wages exclude tips and overtime.
Our practice covers all five Blueprint areas with scenario questions built on client facts — what's income, what's deductible, what basis the property takes. Add flashcards for rules and terms, case simulations that work a return from the facts, and illustrated guides to basis, entity taxation and the contract and agency rules.

Questions built on the AICPA Blueprint
Every question is tagged to an REG content area and Blueprint topic — Circular 230, contracts and agency, basis and depreciation, individual and entity taxation under current law.
Hints that teach the rule
Reveal the rule behind the question — the Code section, the penalty, the basis rule, the legal test. Every answer comes with the full rationale.
Adaptive practice
Questions steer toward your weakest areas, weighted like the real exam, and get harder as you get stronger.
Timed practice exams
Blueprint-weighted multiple-choice exams — 72 questions in 100 minutes, the realistic MCQ share of your 4 hours — with a pacing indicator and full review.
Flashcards, case simulations and guides
120 flashcards, 8 unfolding case simulations in the spirit of task-based simulations — working a client's return or entity choice where each decision changes the tax result — and interactive illustrated guides you explore hotspot by hotspot.
Progress in every content area
Each area moves from Not started to Exam ready, so you know exactly what to study next.
Test at home or at a center
The CPA Exam is given only at Prometric test centers — there's no online or at-home option. Apply through your state board (many use NASBA), get your Notice to Schedule (NTS), then book with Prometric. Core sections test year-round, any day Prometric has a seat, with scores released on a rolling basis.
At a Prometric test center
- Centers across the U.S. and in select international locations — book early, especially near quarter-ends.
- Bring your NTS and unexpired government-issued photo ID with a name that matches it exactly.
- Phones, bags, watches and notes go in a locker; the exam has a built-in on-screen calculator — no personal calculators.
- Allow extra time for check-in and security checks before your 4-hour clock starts.
Exam-day game plan
How to walk in ready — and how to pace 72 multiple-choice questions — the MCQ share of the REG section.
Pacing checkpoints
Checkpoints cover the two multiple-choice testlets (72 questions). The real section also has 8 task-based simulations in testlets 3–5 worth 50% of your score — save roughly 140 minutes for them. AICPA has announced a move to a new testing platform in 2027, with no testing planned July 1–11, 2027 and a slower score-release schedule for a while afterward — if you're planning around mid-2027, check AICPA's and NASBA's current notices.
The week before
- Take one full-length timed MCQ practice exam 3–5 days out, then rest.
- Refresh the OBBBA changes now testable — 100% bonus depreciation, the SALT cap, the enhanced standard deduction and domestic R&E expensing.
- Review basis rules for gifts, inheritances, partnerships and S corporations side by side.
- Confirm your NTS, ID name match and Prometric appointment — and that your NTS hasn't expired.
During the exam
- Spot the taxpayer, the year and the entity type before you calculate anything.
- Read wages and compensation as excluding tips and overtime unless the question says otherwise.
- Pick your best answer, flag it and move on — but review flags before you submit each testlet; you can't go back to it.
- Answer every question — there's no penalty for guessing.
Keep your head
- A few nerves sharpen focus. If you freeze, take three slow breaths and reread the question.
- Some questions are unscored pretest items you can't identify — one hard question tells you nothing.
- 75 is a scaled score against a fixed standard, not 75% correct and not a curve.
After you pass
- In most jurisdictions you now have 30 months from your first passed section to pass the rest (a few use 18 or 36) — check your board's rule and when its clock starts.
- To be licensed you need 3 Core sections plus 1 Discipline, along with your state's education and experience rules and, in most states, an ethics exam; licensed CPAs then complete state-set CPE (commonly about 120 hours every 3 years, including ethics).
- REG pairs naturally with the TCP Discipline if you're heading into tax; otherwise most candidates choose BAR or ISC.
