What is Tax Precedent?

Tax precedent plays a critical role in the U.S. tax system by providing guidance based on previously adjudicated cases or IRS rulings. It acts like a roadmap for taxpayers, tax professionals, and the IRS itself, ensuring similar tax situations are treated consistently over time.

The Legal Foundation of Tax Precedent

The principle behind tax precedent is rooted in “stare decisis,” a Latin term meaning “to stand by things decided.” This legal doctrine compels courts and agencies like the IRS to respect prior rulings unless there is a compelling reason to overturn or modify them. In tax law, this promotes stability and fairness by preventing random or unpredictable outcomes.

Sources of Tax Precedent

Tax precedent originates from multiple sources:

• IRS Rulings: These include formal documents such as Revenue Rulings and Private Letter Rulings, which interpret how tax laws apply to specific facts.
• Court Decisions: Opinions from tax courts like the U.S. Tax Court, federal district courts, circuit courts of appeal, and the Supreme Court.
• IRS Regulations: Also known as Treasury Regulations, these provide detailed guidance on how laws passed by Congress are implemented.

How Tax Precedent Influences Tax Practice

When facing complex or ambiguous tax questions, taxpayers and tax advisors often review existing precedents to determine the likelihood of the IRS’s or courts’ positions. For example, if there has been a prior court ruling denying the deductibility of certain home office decoration expenses, taxpayers should not expect such expenses to be deductible today without new justification.

One contemporary example involves cryptocurrency taxation. Early IRS guidance and subsequent court cases have established a framework for how transactions involving cryptocurrencies are reported and taxed, helping taxpayers understand their compliance obligations.

Who Relies on Tax Precedent?

Tax precedent affects virtually everyone involved in the administration or contesting of tax matters:

• Taxpayers: Gain predictability in tax planning and filing.
• Tax Professionals: Use precedent to advise clients, structure transactions, and support tax positions.
• IRS and Courts: Apply precedent to ensure consistent enforcement and rulings.

Tips for Effectively Using Tax Precedent

• Research relevant IRS rulings and court opinions before making tax decisions.
• Cite precedent when filing appeals or defending audit positions.
• Consult tax attorneys if you question whether established precedent is outdated or unjust.
• Understand the hierarchy of courts; decisions from higher courts carry more weight.
• Recognize that some IRS guidance, such as informal advice, does not create binding precedent.

Common Misunderstandings

• Not all IRS guidance is binding; some serve as recommendations.
• Precedents can be overturned or evolved over time.
• Jurisdiction matters as precedents from one federal circuit may not apply elsewhere.
• The Supreme Court’s tax rulings override those of lower courts.
