Substance Over Form

Accounting
Updated Apr 2026

The accounting principle requiring transactions to be recorded based on their economic reality rather than legal structure.

What is Substance Over Form?

The substance-over-form principle requires that financial transactions be accounted for according to their economic reality rather than their legal structure. This ensures financial statements reflect the true nature of a company's activities. It underpins lease accounting, sale-leaseback rules, and consolidation standards, preventing companies from structuring transactions to achieve a desired accounting outcome.

Example

Example

A company sells equipment to a bank and immediately agrees to lease it back for the asset's remaining life. Despite the legal form of a sale, the economic substance is a secured loan — GAAP requires the company to record it as borrowing, not a sale.
