Civil Service Retirement System (CSRS) INTERIM

Covers employees first hired, rehired or converted to an appointment subject to retirement on or after January 1, 1984. CSRS Interim was a version of CSRS established pending the creation of the new retirement system. When the new system (FERS) was established on January 1, 1987, personnel offices were instructed to review the Official Personnel Folder of all employees covered under CSRS Interim to determine whether or not the employees, by law, were:

• Vested, meaning you had at least 5 years of creditable civilian service under the CSRS. If so, your retirement coverage would be either CSRS or CSRS Offset, or
• If you were not vested in CSRS, you would be covered automatically under FERS.

Civil Service Retirement System (CSRS) OFFSET

CSRS Offset is a version of CSRS established for employees who become subject to Old Age Survivors and Disability Insurance (OASDI), also known as FICA taxes, and have completed at least 5 years of creditable civilian service.

Generally, CSRS Offset coverage applies to employees rehired after a break of more than 365 days with 5 or more years of prior creditable civilian service as of:

• December 31, 1986, or
• As of the date of your last separation and you had at least 1 day of CSRS coverage or Foreign Service Retirement System coverage.
• Employees with at least a 4-day break in service have a 6-month opportunity to transfer to FERS.

Federal Insurance Contributions Act (FICA)

A Federal law that is monitored by the Social Security Administration that requires employees to pay social security tax on their earned income that provides future pension and other social security benefits. The Federal Insurance Contributions Act (FICA) establishes a Social Security and Medicare Tax on employers and employees. The employee's portion of the tax is deducted from the paycheck and then matched by the employer's portion of the tax. The tax applies to:

• Most employees on appointments specifically excluding them from any Federal retirement system coverage. For example, a temporary appointment not to exceed 1 year.
• Most employees first hired in Federal service before January 1, 1984 but were not covered under a Federal retirement system until after December 31, 1983, i.e. temporary employees and,
• Employees rehired after a break in service or break in CSRS coverage (covered service) of more than 365 days, which ended after December 31, 1983.
• Employees first hired on/or after January 1, 1984, with no prior federal employment.
• Employees covered under CSRS Offset and FERS.

Civil Service Retirement System (CSRS)

Covers most employees first hired prior to January 1, 1984.

Employees who have had a break in coverage of less than 1 year (365 days) also retain their CSRS coverage. However, if you have a break in service of at least 4 days, upon rehire you have a 6-month opportunity period to elect to transfer to FERS.

Federal Employees' Retirement System (FERS)

FERS became effective January 1, 1987 and covers most employees first hired on or after January 1, 1984.

Employees rehired after a break in service of more than 365 days with less than 5 years of creditable civilian service.

Employees who elected FERS coverage during transfer opportunities.

FERS is a retirement plan that provides benefits from three different sources: a Basic Benefit Plan, Social Security and the Thrift Savings Plan (TSP). Two of the three parts of FERS (Social Security and the TSP) can go with you to your next job if you leave the Federal Government before retirement. The Basic Benefit and Social Security parts of FERS require you to pay your share each pay period. Your agency withholds the cost of the Basic Benefit and Social Security from your pay as payroll deductions. Your agency pays its part too. Then, after you retire, you receive annuity payments each month for the rest of your life.

The TSP part of FERS is an account that your agency automatically sets up for you. Each pay period your agency deposits into your account amount equal to 1% of the basic pay you earn for the pay period. You can also make your own contributions to your TSP account and your agency will also make a matching contribution. These contributions are tax-deferred. The Thrift Savings Plan is administered by the Federal Retirement Thrift Investment Board.
