Source of Funds / Source of Wealth

Overview

Source of Funds (SoF) and Source of Wealth (SoW) checks determine where a customer’s money comes from and how they accumulated their wealth. Regulators require these checks, particularly for PEPs and high-risk customers, to detect illicit funds.

SoF focuses on the origin of a particular transaction, while SoW considers the broader picture of wealth accumulation over time. Banks and fintechs request supporting documents such as payslips, tax returns, property records, or business ownership evidence. These checks help prevent laundering, corruption, and terrorist financing, while also supporting risk-based due diligence.
