What REG actually tests (2026 AICPA Blueprint)
Plan for roughly 95 hours of focused study for REG (most candidates land between 80 and 110). The personalized plan above tailors this to your stage, timeline, and biggest challenge. Here is the blueprint it is built on.
REG content areas and weights
Area I: Ethics, Professional Responsibilities & Federal Tax Procedures
10-20% · ≈ 14 hrsEthics and responsibilities in tax practice (Circular 230, preparer rules); licensing and disciplinary systems; federal tax procedures (audits, appeals, assessments, collection, judicial process); legal duties and responsibilities.

REG mixes tax computation with rule-recall. As of July 1, 2026, every REG exam tests the OBBBA rules (see the note below), so study the current versions.
OBBBA and your exam date
REG is a tax section, and the One Big Beautiful Bill Act (OBBBA) changed several rules that run through both individual and entity taxation. As of July 1, 2026, OBBBA is testable on REG, so every current REG exam uses the OBBBA versions of these rules. (Candidates who sat before July 1, 2026 tested the prior, pre-OBBBA rules.)
The main OBBBA changes to know for REG:
- SALT (state and local tax) deduction cap raised from $10,000, with a phase-out at higher incomes.
- The §199A qualified business income deduction made permanent (it had been set to expire after 2025).
- 100% bonus depreciation restored permanently, instead of the scheduled phase-down.
- Domestic research and experimental (R&E) costs deductible currently again, instead of 5-year amortization.
- Standard deduction increased and the personal exemption permanently eliminated.
- Child tax credit increased and made permanent.
- Estate and gift exclusion raised, with no scheduled sunset.
- §163(j) business interest limitation returned to an EBITDA-based calculation.
Study the current (OBBBA) version of each figure — the most common OBBBA-era mistake is studying a pre-OBBBA amount that no longer applies.

How many hours should I study for REG?
Plan for roughly 95 hours of focused study for REG. Most candidates spend between 80 and 110 hours, depending on their background, how consistently they study, and their timeline.
Which areas are most heavily weighted on the REG CPA exam?
Under the 2026 AICPA Blueprint, REG covers 5 weighted areas: Area I: Ethics, Professional Responsibilities & Federal Tax Procedures (10-20%); Area II: Business Law (15-25%); Area III: Federal Taxation of Property Transactions (5-15%); Area IV: Federal Taxation of Individuals (22-32%); Area V: Federal Taxation of Entities (23-33%).

Yes.

Candidates who sat before July 1, 2026 tested the prior rules.
