Military Buyback LES Verification: Checking Block 20 and Coordinating With HR

Your LES Is the Early Warning System for Deposit Problems

Your Leave and Earnings Statement is not just a pay stub. For military buyback purposes, it is the first place a payment failure shows up — and the last place a completed deposit should be confirmed before you file for retirement.

Block 20 of the LES displays your military service deposit status, including the current balance owed. Every payment you make — whether through Pay.gov, payroll deduction, or check — should reduce that balance within one or two pay periods. If the number does not move, something went wrong between your payment and the payroll system, and you need to act before the gap becomes a retirement problem.

What Block 20 Shows

Block 20 on a standard federal LES typically displays deduction codes and balances for various retirement-related items, including the military service deposit. The exact format varies by payroll provider (DFAS Civilian Payroll, National Finance Center, Interior Business Center), but you should see:

• The total deposit amount certified by your agency HR
• The balance remaining
• Any deduction amount if you are on payroll deductions

Some payroll systems display the military deposit under a specific deduction code rather than in Block 20 directly. If you cannot find the military deposit on your LES, ask your payroll liaison which field or code to check. The information is there — the labeling is just not consistent across agencies.

The Payment-Posting Gap

The most common deposit problem is a payment that was sent but never posted. This happens more often than you would expect, and it can occur with any payment method:

Pay.gov payments: You get an instant electronic confirmation, but the payment still needs to be processed by your payroll provider before it appears on your LES. This typically takes one to two pay periods (2-4 weeks). If the balance on your LES has not changed after two full pay periods, contact your payroll provider with the Pay.gov confirmation number.

Payroll deductions: The deduction should appear on every LES from the pay period it starts until the balance is zero. If a deduction disappears from one LES without the balance reaching zero, the authorization may have been dropped during a payroll system update or personnel action.

Check payments: These have the longest posting lag — up to 4-6 weeks from the date you mailed the check. If the balance has not decreased after three pay periods, contact your payroll provider with the check number and date mailed.

Coordinating Between HR and Your Payroll Provider

The military buyback process involves two distinct offices within your agency that do not always communicate automatically:

Human Resources (benefits specialist): Certifies your service dates, calculates the deposit amount on the SF 3108/SF 2803, and maintains your electronic Official Personnel Folder (eOPF). HR does not process payments.

Payroll provider (DFAS Civilian Payroll, NFC, IBC): Receives the billing package from HR, sets up the payment schedule, processes your payments, tracks the balance, and issues the Paid-in-Full letter. Payroll does not update your personnel records.

The handoff between these two offices is where deposits get lost. HR sends the certified SF 3108 to payroll, but payroll may take 30 business days to set up the billing. During that window, you cannot make payments because there is no billing record in the system yet. After you pay in full, payroll issues the confirmation letter — but payroll does not send it to HR. You must deliver it yourself.

If your agency uses the National Finance Center (NFC) for payroll processing, NFC has its own timeline for posting payments and generating confirmation letters. The NFC Help Desk (1-855-632-4468) can look up your deposit record by Social Security number and confirm whether a payment has been received and posted.

The eOPF Verification

Your electronic Official Personnel Folder should contain the following military buyback documents once the process is complete:

• Copies of your DD-214 (all periods of service)
• Certified RI 20-97 (estimated earnings from DFAS)
• Completed SF 3108 (FERS) or SF 2803 (CSRS) with agency certification
• Paid-in-Full letter from your payroll provider
• Updated SF-50 reflecting your corrected Service Computation Date

Check your eOPF access portal to verify these documents are present. If any are missing — especially the Paid-in-Full letter — your retirement package will be incomplete when your agency submits it to OPM.

The Paid-in-Full letter is the critical handoff. Your payroll provider generates it. You deliver it to HR. HR uploads it to your eOPF. If any link in that chain breaks, OPM processes your retirement without crediting the military service.

What to Do When Something Is Wrong

If your LES shows an incorrect balance, a missing deduction, or no military deposit entry at all, escalate in this order:

1. Contact your payroll liaison (the person in your office who handles LES questions). They can check the payroll system for your deposit record.

2. Contact your payroll provider directly. For NFC: 1-855-632-4468 or [email protected]. For DFAS Civilian Payroll or IBC, use the contact on your agency's benefits page. Ask them to confirm (a) whether a billing record exists for your military deposit, (b) what payments have been received and posted, and (c) the current balance.

3. Contact your HR benefits specialist if the payroll system shows the deposit as complete but your LES or eOPF does not reflect it. This indicates a sync issue between payroll and personnel records.

Document every call: date, who you spoke with, what they told you, and any case or ticket numbers. If the issue is not resolved within one pay period, follow up in writing (email creates a paper trail that phone calls do not).

The Military Buyback Guide for Federal Employees includes an agency contact log template designed specifically for tracking these multi-office escalations, so you never lose track of who told you what.
