CPA Tax Research Process: Get the Facts Before Concluding

Answer B. Tax research begins by resolving all material facts because authority weight and applicability depend on factual similarity. The CPA should clarify the unclear fact first, then compare the revenue ruling, the private letter ruling (informative but not precedential for other taxpayers), and secondary sources against the clarified facts.

Why not A: Tempting because published revenue rulings are formal IRS guidance and often carry significant weight. It fails because you cannot know which authority is more analogous until the material fact is resolved; a published ruling may still be less analogous to the client's actual facts than another source.

Why not C: Tempting because a favorable PLR plus persuasive commentary can seem to bolster a position. It fails because a PLR binds only the taxpayer to whom it was issued and is not precedential for others; moreover, factual differences (including the unresolved material fact) may undermine its applicability.

Why not D: Tempting because court opinions are highly authoritative. It fails because waiting for controlling case law is unnecessary and impractical when none exists; administrative guidance and facts-based analysis remain relevant and must be applied once the client's facts are clarified.

Answer B. Substantial authority is assessed by weighing the applicable primary authorities that support the position against those that contradict it. It is the relative legal weight and relevance of authorities, not a tally of secondary-source summaries or the raw count of materials, that determines whether substantial authority exists.

Why not A: Tempting because more supporting items can feel persuasive, but substantial authority depends on the weight and relevance of applicable primary authorities rather than the simple count of sources (especially secondary sources).

Why not C: Disclosure may affect penalty considerations but does not determine whether substantial authority exists; the legal support for the position must be measured by the applicable authorities themselves.

Why not D: The magnitude of the tax benefit is a planning consideration but does not establish legal support. A position's tax effect does not change the governing standard for substantial authority.

Answer B. Tax conclusions must be based on the facts. When a material fact is unresolved, the CPA should obtain that fact if possible and explain how different fact patterns would change the tax result rather than asserting a single answer. This approach preserves professional integrity and informs the client of the risks and alternatives.

Why not A: Tempting because it appears to help the client, but choosing the most favorable treatment without verifying the fact is not supportable; conclusions should be grounded in confirmed facts, not client-preferred assumptions.

Why not C: More research is useful, but it cannot substitute for a missing fact when the tax result turns on that fact; finding an authority that appears to favor one outcome doesn't resolve factual uncertainty.

Why not D: This is overly cautious; the CPA can still identify the missing fact, assemble the relevant authorities, and explain alternative outcomes and their implications while awaiting confirmation.

Answer B. A practitioner who knows of a client's error must promptly advise the client of the noncompliance and its consequences. Absent the client's consent or a legal compulsion, the practitioner should not disclose confidential client information to the IRS. Because the Year 1 error affects Year 2, Moss should not prepare the current return in a way that knowingly perpetuates the incorrect carryover treatment.

Why not A: Tempting because it sounds like a strict compliance reaction, but incorrect: confidentiality rules generally prevent disclosure to the IRS without client consent, and immediate cessation of all work is not the required response; the key duties are to advise the client and avoid preparing returns that knowingly perpetuate errors.

Why not C: Incorrect because a preparer may not knowingly carry forward an incorrect tax treatment merely because the client signed the prior return; the preparer must not prepare a current return that intentionally repeats a known error.

Why not D: Incorrect because the duty to inform the client and to avoid perpetuating a known error does not hinge on the size of the understatement or on whether penalties might apply; knowingly repeating an incorrect carryover is not appropriate.

Answer D. IRS publications and newsletter articles are secondary, background sources and do not by themselves provide controlling authority. A defensible tax recommendation starts with researching applicable primary authorities (the Code, regulations, rulings, and case law) and then applying those authorities to the client's confirmed facts.

Why not A: This is tempting because agreement between two sources seems reassuring, but consistency of secondary sources does not replace primary authority. The CPA must verify controlling law before advising the client.

Why not B: This is tempting because the publication comes from the IRS, but IRS publications are general guidance for taxpayers and are not controlling authority like the Code, regulations, rulings, or court decisions.

Why not C: This is tempting because disclosure can affect audit outcomes, but disclosure does not substitute for proper research, disclosing an unsupported position does not make it correct or adequately defended.
