Which Federal Departments and Agencies Are Covered Under FERS?

One of the most common misconceptions about federal employment is that all government jobs have the exact same retirement system.

In reality, retirement eligibility can vary depending on the agency, the position, your hiring date, and whether you qualify for special retirement coverage.

For most civilian federal employees hired after 1983, the primary retirement system is FERS — the Federal Employees Retirement System.

What Is FERS?

FERS is the primary retirement system for most civilian federal employees.

It typically includes:

Together, these create the foundation of federal retirement planning.
