Can a Business Deduct Legal and Professional Fees?

Legal/professional fees are generally deductible when arising from ordinary business matters, but capital-transaction fees can require capitalization.

Reviewed August 2026 · Mint Associates Ltd Co · Houston, Texas

How it works

The rule, and what it turns on.

The origin-of-claim doctrine focuses on the underlying matter.

Example

Attorney fees defending a routine contract dispute may be deductible; legal costs acquiring a building generally go to basis.

Common mistakes

What we see go wrong, and what we do instead.

  • Deducting every legal invoice automatically.

A better approach

  • Ask counsel to break invoices down by matter when treatment differs.

Authority

Where this comes from, so you can check it.

IRC §162 or §212 where applicable; capitalization may apply under IRC §263; origin-of-claim doctrine.

Relevant case law

United States v. Gilmore, 372 U.S. 39 (1963) - deductibility of legal fees generally follows the origin and character of

the claim.

Commissioner v. Tellier, 383 U.S. 687 (1966) - ordinary and necessary legal expenses may be deductible despite an

unfavorable context, absent a sharply defined public policy bar.
