Federal Interim Retirement Pay: How Much and When It Arrives
Federal interim retirement pay explained: what share of your annuity to expect, when deposits start, what's withheld, and when to check on a stalled claim.
A smaller first retirement payment can be unsettling when you are trying to plan your income after leaving federal service. For FERS and CSRS retirees whose applications are in OPM processing, federal interim retirement pay is the partial monthly annuity OPM sends while it finishes calculating their full benefit. OPM says interim payments typically cover 60 to 80 percent of your estimated net annuity. Once a claim is finalized, OPM reconciles interim payments with the final annuity and may issue an adjustment payment if money is owed.
OPM's quick guide estimates 30-45 days for your agency's payroll processing, 10-15 days for OPM intake, and 10-90 days for review and calculation, which is why it says most retirees see their first full annuity check 3 to 5 months after retiring. That means budgeting on a reduced interim payment for several months rather than a few weeks. Some routine deductions are temporarily suspended during interim payments, so don't expect these checks to mirror a normal paycheck's withholdings.
Interim federal retirement pay: what's normal at each stage
Interim pay tends to follow a predictable pattern. Compare what's happening in your case with what's typical below, and use it to spot the moments that call for a closer look.
| Your situation | What's normal here | What it means and what to do |
|---|---|---|
| Your former agency hasn't sent your retirement records to OPM yet | Your former agency's payroll office is still preparing and forwarding your retirement package | OPM estimates this stage at 30-45 days. Questions at this point go to your former agency's payroll or HR office, since OPM doesn't have your case yet. |
| OPM has your package, but you don't have a claim number yet | OPM is establishing your case file and assigning your CSA claim number | OPM estimates this case-setup step at 10-15 days. |
| You have a claim number, but your first interim deposit hasn't arrived | OPM generally sets up your case and begins interim pay during this intake stage; the 10-15 day window is an overall stage estimate, not a guaranteed deposit date for your case | If that window has passed and you're concerned, check your case in Services Online, or call OPM Retirement Services at 888-767-6738 with your CSA claim number. |
| Deposit lands far below the usual 60 to 80 percent range | OPM says interim payments are typically 60-80% of your estimated net annuity — a typical range, not a guaranteed floor, and not a percentage of a gross calculator estimate | Your claim is still provisional while OPM reviews and calculates your benefit, so compare this deposit against your next one. If it stays substantially below what's typical, or remains unexplained, check Services Online or contact OPM Retirement Services with your CSA claim number. |
| Health insurance premiums aren't showing as deducted | Health coverage you elected to take into retirement continues during processing | OPM's guide confirms elected coverage carries over while your claim is processed. This isn't extra savings — unpaid premiums are collected retroactively once OPM sets your final deductions. |
| Your interim deposit doesn't match the deductions you'd expect from a regular annuity | Some routine deductions are temporarily suspended during interim pay | Only federal income tax is withheld during interim pay; other deductions resume once OPM finalizes your claim and sets your final deductions. |
| Your claim has been finalized | OPM has confirmed your service and salary history, sick leave credit, survivor election, service-credit deposits or redeposits, and benefit deductions, and your regular deductions resume with your first full annuity payment | This review is what turns interim pay into your regular ongoing annuity. |
Interim retirement pay is the partial annuity the Office of Personnel Management (OPM) sends while it reviews a retirement claim, keeping some income flowing during that gap. It is not the final annuity, so base short-term decisions on the interim amount rather than the benefit you expect after the claim is complete.
Why the interim amount is a conservative estimate
OPM's retirement quick guide describes interim payments as typically 60 to 80 percent of your estimated net annuity, meant to help cover expenses while the case is processed.
That range is deliberately conservative because OPM sets the interim amount before your service and salary history are fully verified, so the figure stays cautious until the file is complete. Because the case file isn't finished, an individual deposit can land anywhere within that range rather than at a predictable midpoint, and it's worth treating the check as a placeholder rather than a preview of your regular annuity.
That estimated net figure also isn't something you can reverse-engineer from a retirement calculator. OPM's 60-to-80-percent range applies to an estimated net annuity, not to the gross number a FERS or CSRS calculator produces. Use a calculator to understand the full annuity you're working toward, then rely on your actual interim deposit, not a percentage of a gross estimate, for near-term spending decisions.
From separation to your first regular payment
OPM cannot begin interim payments until it receives the retirement package prepared by the former agency, and the timeline separates agency and payroll processing from OPM's intake and review. Once the employing agency forwards a complete application, OPM assigns a Retirement Claim number — also called a CSA number — and sets up interim payments as part of its intake process.
OPM's retirement quick guide lists rough stage estimates: about 30-45 days for agency and payroll processing, 10-15 days for OPM intake, and 10-90 days for OPM's review and calculation of benefits. The guide adds that most retirees receive their first full annuity check within 3-5 months of retiring, though it presents these as current estimates rather than a guaranteed date for every claim.
OPM's quick guide names missing signatures as one of the most common causes of delay. If OPM or your former agency requests a signature, a supporting document such as a marriage certificate or military record, or completion of an open service-credit deposit or redeposit, returning it right away is the fastest way to keep your claim moving. (If you're still planning your retirement date, downloading your personnel records before you leave is worth doing too, since access to your electronic Official Personnel Folder (eOPF) typically ends after separation.)
What comes out of an interim payment
OPM withholds only federal income tax from interim payments. Health benefits and life insurance premiums aren't deducted at this stage; instead, they're collected once OPM finishes processing your application, retroactive to your annuity's start date. That's part of why an interim deposit doesn't look like a scaled-down version of a regular annuity check: those other deductions simply aren't being taken yet.
The federal tax withheld from your first interim payment can run higher than what's withheld from later interim payments and your regular annuity. OPM's interim pay FAQ explains that it makes tax withholding adjustments once it finishes processing the claim, which is why that first check's withholding often doesn't match the pattern that follows.
Health and life insurance while the claim is processing
If you were eligible to continue FEHB or FEGLI and elected to carry that coverage into retirement, OPM says that coverage continues while you receive interim pay. If you're unsure whether your enrollment carried over correctly, OPM's interim pay FAQ explains how to submit a help request using your CSA claim number, and Services Online is where you can check your claim's overall processing status.
What happens when your claim is finalized
OPM's quick guide describes "Retirement Finalized" as the stage when it deposits your first regular monthly payment, replacing the interim deposits you received while your case was under review. That regular payment reflects the completed calculation of your annuity and its deductions. If additional annuity money is due for the interim period, OPM issues an adjustment payment to cover the difference; for retirees who carried FEHB or FEGLI into retirement, this is also when OPM begins withholding those premiums, retroactive to the annuity's start date.
Once that first regular payment arrives, compare it against the interim deposits you tracked during processing. If your interim deposits sat well below the 60-to-80-percent range OPM describes, or your first regular payment hasn't arrived within the guide's 3-to-5-month estimate, that's a reasonable point to follow up rather than assume the delay or the amount will sort itself out.
Where to direct a question depends on which stage your claim is in. Before OPM has assigned a CSA claim number — meaning your package is still with your former agency — payroll and HR questions belong to that agency. Once OPM has issued a CSA number, Services Online and OPM's interim pay FAQ are the channels the guide designates for tracking your claim, and that claim number is the reference point for any follow-up on a payment that looks late or clearly incorrect.
Budgeting for a wait without a guaranteed end date
Build regular spending around the lower interim deposit you are receiving, not around an assumed final amount. Start with housing, utilities, food, debt payments, and other fixed obligations, then decide what flexible spending can wait. A cash cushion can reduce pressure while the claim is still interim.
OPM's 3-5 month estimate gives a useful planning frame, but it does not guarantee a personal end date. Avoid timing a large optional purchase or a new recurring expense around the assumption that the final annuity will arrive in a particular month.
To see the full annuity you're working toward, try the FERS retirement calculator if you're under the Federal Employees Retirement System, or the CSRS retirement calculator if you're under the Civil Service Retirement System. Either result is a gross estimate, so plan near-term spending from your actual interim deposit instead. For anyone also considering a next career step after federal service, FedUp.work can help translate public-service experience into private-sector language.
Keep a simple record of each interim payment's date and amount, and track your claim's progress through Services Online.

Common questions about federal interim retirement pay
How does OPM figure out my interim payment amount?
OPM bases interim payments on the salary and service details from your initial retirement application, then pays a share of your estimated net annuity while it verifies the rest of your record. OPM's retirement quick guide puts that share at roughly 60 to 80 percent of your estimated net annuity.
What day of the month will my interim payment arrive?
OPM's guidance on annuity payments states that payments are usually made on the first business day of each month, and that each monthly payment covers the previous month's benefit — so a payment issued in early April, for example, is for March. If a payment misses that date, sign in to OPM Retirement Services Online, or call the OPM Retirement Information Office at 888-767-6738 with your CSA claim number.
How long does the interim period usually last?
OPM's retirement quick guide reports that most retirees receive their first full annuity check within 3 to 5 months of retiring.
Will I get back the difference between my interim payments and my final annuity?
When OPM finishes processing your claim, if the completed calculation and applicable deductions show that additional annuity money is due, OPM issues an adjustment payment to make up the difference between your interim payments and your finalized annuity amount, according to OPM's retirement quick guide. At that same point, OPM also begins withholding your health and life insurance premiums retroactive to your annuity's start date. See OPM's interim pay FAQ for details.
What should I do if my interim deposit looks unusually low?
A lower first deposit isn't automatically a mistake, since the 60 to 80 percent range applies to your estimated net annuity rather than a calculator's gross figure. If it stays well below that range, check your case in OPM Retirement Services Online or call the OPM Retirement Information Office at 888-767-6738 with your CSA claim number.
