Government Set-Asides Explained: 8(a), HUBZone, SDVOSB, and WOSB Programs

What Are Set-Asides?

Federal agencies are required to award a percentage of contracts to small businesses. Set-aside programs restrict competition on certain contracts to businesses with specific certifications, giving qualifying companies a significant competitive advantage.

In fiscal year 2025, the federal government awarded over $175 billion in contracts to small businesses through various set-aside programs.
