If you are separating from Federal service for retirement purposes, keep in mind that you might not receive your initial annuity payment from OPM until approximately 5 to 7 weeks from the date of your separation.  You should be prepared for this lapse of income period.


Also keep in mind, depending upon OPM’s staffing and workload, it can take anywhere from 3 to 6 months (on average) to execute the final adjudication of your retirement.  Some retirements are more complicated to compute than others, and OPM wants to triple-check everything before they finalize your retirement.  OPM doesn’t want to over pay anyone, but they understand that annuitants need their income so they place folks into “interim retirement pay” status.


These initial 3 to 6 monthly annuity payments from OPM can often range somewhere between 40% to 80% of what you expect to receive as your Net income, although OPM’s goal is to provide the annuitant with approximately 90% of the expected Net monthly payment, less Federal income tax withholding.


The duration and percentage of interim retirement pay can be affected by the following:


-When applicable, the FERS Supplement is usually not included in interim retirement pay

-Special Group computations required for LEOs, Firefighters, and Air Traffic Controllers

-CSRS Offset computations if CSRS Offset retiree will be 62 within 90 days (or is already 62)

-Court ordered benefits for a former spouse (filed with OPM)

-Part time service

-Unpaid deposit/redeposit service (if required for retirement purposes)

-Unverified or missing service

-Insurable Interest survivor election made

-No survivor election made

-Waiver of military retired pay is not verified, when applicable



Once OPM finalizes your retirement and verifies that any applicable taxes are withheld and premiums for insurance are paid, they will retroactively pay you a lump-sum for any previous underpayments (including any unpaid FERS Supplement amount, if applicable)… but meanwhile, you still have bills to pay.


This might not be that big of a deal if you have a post-retirement job lined up to immediately transition in to… and/or you have a spouse who is still working… and/or you have enough money saved to help cover your living costs while waiting for OPM to finalize your retirement.


When you separate from Federal service for retirement purposes, unless you have another job lined up, you will be transitioning from receiving income on a biweekly basis to a monthly basis.  When preparing to retire, it would be good to speak with your agency retirement counselor to determine when your last pay date will be for your final pay and unused annual leave.  Compare this to when you might expect to receive your initial annuity payment from OPM and be aware of how long you might expect to be in interim retirement pay status.  Depending upon your financial needs, you may or may not be okay with this lapse of income period, but at least you can start planning and be prepared for this.


For multiple personal reasons, many Federal employees aren’t necessarily ready to withdraw income from their Thrift Savings Plan (TSP) immediately upon separation from Federal service.  But it’s good to be aware of your withdrawal options so you can plan for the future… whether you intend to postpone TSP withdrawals or not.  Regardless, when you are ready to exercise your withdrawal options from TSP, you will be communicating with TSP… not OPM.  Applying for income from TSP is a separate application process from applying for retirement from Federal service.


Just keep in mind, it will often take approximately 2 to 4 weeks (from the date of your separation from Federal service) for your agency to notify TSP that you are no longer employed.  You will not be able to exercise your post-employment TSP withdrawal options until TSP receives this notification from your agency.
