TAX 670: Tax Research Methodology

A study guide to SNHU's TAX 670, the graduate course on federal tax research methods and representing clients before the IRS.

Updated October 2026 · 5 min read

TAX 670 is a graduate course at Southern New Hampshire University (SNHU) on the methods and techniques of federal tax research. SNHU lists it at 3 credits, and its description also covers the rules and procedures for representing clients before the Internal Revenue Service.

The challenge is that tax research is a method, not a body of facts. You are marked on how you find, weigh and apply authority, so a correct conclusion without a clear trail of support rarely earns full marks.

Key Concepts Explained

The Research Cycle

A common approach has five steps: establish the facts, identify the issue, locate relevant authority, analyze how the authority applies, and communicate a conclusion. Keeping to the cycle stops you from searching before you know what you are asking.

Illustration (invented question, method only): "Can a client deduct a particular cost?" First state the facts. Then the issue: does this cost fall within the category the law allows? Then find the primary authority and any interpretation of it, apply them to the facts, and conclude with a confidence level and any open points.

Weight of Authority

Not every source carries the same weight. Statutes and regulations are primary authority, administrative guidance and court decisions carry different weight, and commentary is secondary. Say which kind of source you rely on and why it matters.

Representation Standards

Representing a client before the IRS has rules about who may do so and the duties involved. Learn the vocabulary and be precise about what is permitted.

Typical Assignments and How to Approach Them

The course sets exact tasks. The formats below are common in tax research courses and are general guidance only.

Assignment typeWhat it testsHow to approach it
Research memoIssue, authority, analysis, conclusionUse a fixed structure and cite every authority
Client letterTranslating findings for a non-expertLead with the answer, explain in plain language, note limits
Authority evaluationWeighing sourcesRank sources by weight and explain any conflict
Representation scenarioApplying procedural rulesIdentify the rule, the facts and the permitted action

Anatomy of a Strong Research Memo

SectionWhat it contains
FactsOnly the facts that matter, stated neutrally
IssueA specific question the law can answer
AuthorityRules and sources, with weight noted
AnalysisHow the rules apply to these facts, including counterpoints
ConclusionThe answer, its strength and next steps

Markers often check the analysis section most closely, because it shows reasoning. Resist the urge to quote at length; explain how the rule works on the facts instead.

Keeping a Research Log

Record each search, the sources you opened, which you kept and why. A log makes it easy to cite accurately, shows your method, and helps you explain your path if a reader asks how you reached a conclusion.

The log also helps when sources conflict. Note which carries more weight and why, so the memo can state the conflict openly.

What a Strong TAX 670 Submission Looks Like

A strong memo has an issue narrow enough to be answered and a conclusion that actually answers it. Each statement of law has a citation, and the analysis explains why the authority applies to these facts, not just that it exists.

It also shows judgment about the weight of sources and acknowledges where authority is uncertain. A reader should be able to retrace your steps from the memo alone.

Questions to Ask Your Instructor

Ask which databases or sources the course expects you to use, how citations should be formatted, and how long a memo should be. Ask also whether the course wants a firm conclusion or a range of likely outcomes where authority is uncertain. Clear answers early prevent rework.
