The Office of Advocacy supports businesses with fewer than 500 employees, non-profit organizations, and independent contractors. Our mission is to help small entities as regulations are developed in Washington.

We are the independent voice for small businesses in the executive branch. We do not take part in SBA’s work on loans, disaster relief, or procurement.
