Primary vs. Secondary Tax Authorities
| Authority Level | Examples | Binding Status & Weight |
|---|---|---|
| Primary (Legislative) | U.S. Constitution, Internal Revenue Code (IRC), Tax Treaties | Highest authority. The IRC is the foundation of all U.S. tax law. |
| Primary (Administrative) | Treasury Regulations, Revenue Rulings, Revenue Procedures, Private Letter Rulings (for the taxpayer only) | Highly authoritative. Treasury Regulations provide official IRS interpretation of the IRC. |
| Primary (Judicial) | U.S. Supreme Court, Circuit Courts of Appeals, U.S. Tax Court, U.S. District Courts, U.S. Court of Federal Claims | Binding on taxpayers depending on the court and jurisdiction. Supreme Court is binding on all. |
| Secondary | Tax journals, treatises (e.g., BNA Portfolios), newsletters, commercial tax services (e.g., CCH, RIA) | Not binding. Useful for understanding an issue and finding primary sources, but never citable as legal authority. |
Maria, a CPA, is preparing the 2026 tax return for her client, Innovate Corp. While reviewing Innovate's prior-year records, she discovers that a material amount of revenue from a consulting project was inadvertently omitted from the 2025 tax return, resulting in a substantial understatement of tax. According to Treasury Circular 230 and the AICPA Statements on Standards for Tax Services (SSTS), what is Maria's primary professional responsibility upon discovering this error?
The 6 Steps of Tax Research
Scenario: A client, a C-corporation, paid for its CEO's country club membership dues, which the CEO uses for both personal leisure and entertaining business clients. The client wants to know if the dues are deductible.
- 1. Establish the Facts: Gather all relevant details. What is the total cost of the dues? What percentage of the club's use is for business versus personal? Are detailed records kept of the business use?
- 2. Identify the Question(s): The primary question is: Are club membership dues deductible as a business expense? A secondary question might be: If the dues are not deductible, are the specific costs of business meals and entertainment at the club deductible?
- 3. Locate Potential Authorities: Start with the highest authority. A search for 'club dues' leads to Internal Revenue Code (IRC) §274, which explicitly disallows deductions for club dues. Then, search for Treasury Regulations, Revenue Rulings, and court cases that interpret §274, especially concerning what constitutes a 'club' and the treatment of related business expenses incurred at the club.
- 4. Evaluate and Weigh Authorities: This is the critical step. IRC §274 is primary, binding authority that directly answers the main question. Treasury Regulation §1.274-2 confirms this disallowance. These primary sources are far more powerful than any secondary source, like a tax journal article, that might argue for deductibility.
Common CPA Exam Distractors on IRC § 274
- 1Use this 4-step framework to dissect any ethics or standards question on the REG exam.
- 2Step 1. Identify the Governing Authority. Is the question about an AICPA member (SSTS applies), any tax practitioner before the IRS (Circular 230 applies), or both? The question's wording ('CPA,' 'tax preparer') is your first clue.
- 3Step 2. Pinpoint the Specific Action. What is the professional doing? Preparing a tax return (SSTS No. 1, Circ. 230 §10.34)? Providing written advice (Circ. 230 §10.37)? Using estimates (SSTS No. 4)? Discovering an error on a prior return (SSTS No. 6)?
- 4Verify effective dates and current-year inflation adjustments before computing dollar caps or penalty rates.
