A post-56 military deposit refers to a payment that eligible federal employees may make to the federal retirement system for their military service performed after 1956. This rule was established to allow federal employees to “buy back” their post-1956 military service and have it count toward their retirement under the Civil Service Retirement System (CSRS) or Federal Employees Retirement System (FERS).

Key terms include:

• Military service credit: Time served in the uniformed services that may be counted toward your federal retirement,
• Deposit: The payment made to cover retirement system contributions for eligible military service,
• Post-56: Refers to service performed after December 31, 1956.

Who needs to consider this deposit

If you are a federal employee or retiree—including members of the USPS or other federal agencies—with military service after 1956, you should consider whether a military deposit is necessary. This especially impacts employees planning to retire under CSRS or FERS, as your retirement credit may depend on making this deposit. Even federal employees who are now retired but had combined federal and military service may need to understand how previous decisions affect their current benefits.

Why Do Deadlines Matter for Retirees?

Effect on retirement credit

Deadlines for making a post-56 military deposit are critical because your eligibility to include military service toward your retirement credit often hinges on timely payment. If you make the deposit by the required deadline (commonly before your separation from service or at least two years before retirement), your qualifying military service is included when calculating retirement benefits—potentially resulting in more years of credit, a higher pension, and earlier eligibility for retirement.

Consequences of missing deadlines

Missing the deadline can have lasting effects. If you fail to make the necessary deposit, your post-56 military service will typically not count toward your federal retirement credit under FERS. For CSRS employees, failing to pay usually results in a reduced annuity. As a result, your pension amount and even your eligibility for certain retirement programs or benefits may be lower than anticipated. This is why it’s so important to understand your personal deadlines and act promptly.

How Does the Deposit Process Work?

Required paperwork and documentation

To make a post-56 military deposit, you’ll need to gather essential documents:

• Proof of military service, usually a certified copy of your DD Form 214 (Certificate of Release or Discharge from Active Duty), which verifies your dates of service.
• Earnings statement for your military service, so your employing agency can calculate your deposit amount.
• Request forms provided by your human resources office or agency, required to begin the process.

Steps federal employees must follow

1. Contact your agency’s human resources or personnel office. Ask for guidance and the appropriate forms to initiate a military deposit.
2. Submit your military service documentation (including the DD 214 and earnings statement) to your agency.
3. Request a deposit calculation from your agency. They will determine the required deposit amount based on your earnings during your service.
4. Make the deposit payment. You can pay in a lump sum or select a payment plan, but the full amount must be paid by the deadline for the service to count.
5. Obtain confirmation in writing that your deposit has been processed and posted to your retirement record.

Starting early in your federal career can help ensure your paperwork is processed well before retirement.

What Happens If You Miss the Deadline?

Implications for future benefits

Missing the deposit deadline means your post-56 military service may not be credited toward your retirement. FERS employees who don’t pay the deposit generally lose credit for that period, reducing total service years and, therefore, potential pension income. While CSRS employees may still be eligible for some credit, their annuity is usually reduced, sometimes significantly, depending on the length of uncredited service.

Options for those who missed it

Even if you miss the initial deadline, it can be helpful to speak with your HR office or retirement specialist. Options may be extremely limited, but in rare circumstances—such as administrative errors or extenuating circumstances—there may be avenues for appeal or reconsideration. In most cases, however, once the deadline has passed, the opportunity to make the deposit and receive the retirement credit is lost. Staying proactive is your best strategy to preserve all possible benefits.

Does Military Service Always Count Toward FERS?

Eligibility rules for federal employees

Not all military service automatically counts toward your federal retirement under FERS or CSRS. To be eligible, your military service must be “honorable,” performed after 1956 (for post-56 deposits), and not already credited toward a military retirement based on 20+ years of active-duty service (with some exceptions). If you are receiving a military pension for non-disability service, you typically cannot use that same period for federal retirement credit unless you waive the military pension.

Service exceptions and nuances

There are exceptions and nuances. Some types of military service, such as National Guard duty (unless under certain federal orders), may not be creditable. Similarly, certain reservist or inactive duty might not count unless it meets federal eligibility rules. If you receive a disability pension or your service was not honorable, that time may also be ineligible for retirement credit. It’s crucial to check with your agency’s retirement experts for clarification based on your unique work and service history.

Frequently Asked Questions

Common concerns about military deposits

Many federal employees want to know the exact amount required for the deposit, payment options, or processing times. It’s common to ask whether making the deposit is worth it, but the ultimate impact on your retirement benefits is highly personal.

Where to find official guidance

For official, up-to-date guidance, consult your agency’s HR or retirement office, or visit resources from the Office of Personnel Management (OPM). These organizations provide the most reliable forms, calculators, and procedures for handling post-56 military deposits. Remember: only official sources and your employing agency can confirm your personal requirements and deadlines.
