READING YOUR FEDERAL
LEAVE & EARNINGS STATEMENT
What Your Pay Codes and Deductions Mean for Retirement Planning
Reviewed & updated: August 26, 2026
Quick answer: a federal leave and earnings statement (LES) is your pay-period record of earnings, deductions, and leave balances. The exact codes vary by payroll provider (DFAS, NFC, IBC, GSA), but nearly every entry falls into seven categories — and several of them are direct inputs to your future retirement picture. This guide explains each category in plain English and the questions each one raises for retirement planning. It does not interpret any individual statement.
The Seven Categories on Almost Every LES
| Category | Common entries | Why it matters for planning |
|---|---|---|
| Earnings | Base pay, overtime, night differential, Sunday premium, locality pay, awards | Your basic pay is used in your high-3 average salary — generally your highest-paid 36 consecutive months of service — which is used in your pension computation. Knowing which entries count as basic pay, and which premiums generally do not, helps you understand your future annuity inputs. |
| Retirement deductions | Federal Employees Retirement System (FERS) or Civil Service Retirement System (CSRS) employee contribution (retirement plan code and percentage) | Confirms which retirement system you are in and that contributions are being withheld. Your retirement code is one of the first things to verify when reviewing your records. |
| Thrift Savings Plan | Traditional TSP, Roth TSP, agency automatic (1%) and matching contributions | Shows whether you are contributing enough to receive the full agency match and how your payroll deferrals accumulate toward retirement savings. |
| Insurance premiums | FEHB (health), FEGLI (life), FEDVIP (dental/vision), FLTCIP where applicable | These elections often carry into retirement under their own continuation rules, so understanding what you currently carry helps you prepare eligibility questions for your HR office. |
| Taxes | Federal income tax, state/local tax, Social Security (OASDI), Medicare | OASDI withholding is one indicator of Social Security coverage, which matters for how your federal benefits and Social Security may coordinate later. |
| Leave balances | Annual leave, sick leave, accrual rates, use-or-lose amounts | Your sick leave balance converts to service credit at retirement, and annual leave is generally paid as a lump sum — two very different retirement outcomes worth understanding early. |
| Allotments & other | Savings allotments, union dues, garnishments, charity deductions, debt repayments | These reduce take-home pay but stop or change at retirement. Listing them helps you sketch how your retirement cash flow differs from your working cash flow. |
A Simple Review Habit
Once or twice a year, pull your latest statement and ask three questions: Is my retirement plan code what I expect? Am I contributing enough to TSP to receive the full agency match? Are my leave balances what I think they are? Anything that looks off is a question for your agency payroll or HR office — they hold your official records and can correct them.
Your sick leave balance in particular becomes retirement service credit — our sick leave conversion guide shows how the hours translate into computed time.
Where to Get Statement-Specific Help
For questions about a specific code, amount, or correction, contact your agency payroll or HR office, or your payroll provider’s help resources — they are the only ones who can act on your records. For general planning conversations, Benefit Reviews can connect you with an independent, licensed professional whose role is educational decoding and planning discussion — not payroll, tax, legal, or personalized financial advice, and not employed by us. See our partners page for how that works.
