GAAP (Generally Accepted Accounting Principles)
The standard framework of accounting rules and conventions that U.S. organizations follow to prepare consistent, comparable financial statements.
GAAP is set by the Financial Accounting Standards Board (FASB), and for nonprofits specifically, FASB’s Accounting Standards Update 2016-14 reshaped how net assets are classified and disclosed — consolidating what used to be three donor-based categories into the two used today: with donor restrictions, and without donor restrictions.
Following GAAP matters most at two moments: when an external CPA firm performs an audit (auditors test compliance with GAAP, not just internal policy) and when a funder or lender requires GAAP-basis financial statements as a condition of a grant or loan. Smaller organizations without an audit requirement sometimes use a simplified or cash/tax basis internally, but almost always need to convert to GAAP for any audited or reviewed statements.
Because GAAP is a living standard — FASB periodically issues updates like ASU 2016-14, or newer guidance on gifts-in-kind — nonprofit finance teams need to track when new standards take effect and adjust reporting accordingly.
