How to read your LES

1. What the LES is — and why it matters

Your Leave & Earnings Statement is the biweekly pay stub of the federal world — but calling it a “stub” undersells it. It’s a complete financial snapshot of a single pay period: exactly what you earned, every dollar taken out and why, what landed in your account, and how much annual and sick leave you have banked. Depending on your agency, you’ll find it in a system like Employee Express, myPay, or an agency portal, and a new one appears every two weeks whether or not you ever open it.

Most feds don’t open it — and that’s a quiet, expensive habit. Your LES is where you confirm you’re actually getting your full TSP match (free money that’s easy to accidentally lose), where a payroll error first becomes visible, where a raise or a health-plan change shows up, and where you verify the leave you’re earning is being credited. Errors in federal payroll are not rare, and an unnoticed one can compound for months before anyone catches it. Learning to read this document is one of the highest-return, lowest-effort money skills a federal employee can build.

There’s a bigger-picture reason too. The gap between what you earn and what you take home — often 30 to 40% — isn’t waste; it’s the sum of a dozen decisions about your future, your protection, and your taxes. Once you can read your LES, those become choices you control rather than mysteries you accept. It’s the raw data behind everything else — your budget, your financial order of operations, your retirement plan — all of which start with knowing what you actually make and where it goes.

Practically, you access your LES through whatever payroll system your agency uses — Employee Express, myPay (DFAS), the National Finance Center’s portal, or an agency-specific site — and it’s usually posted a few days before payday. A worthwhile habit: download and save each one as a PDF, at least the final statement of each year. Your LES history is the cleanest proof you have of pay, deductions, and leave, and it can matter years later — reconciling a retirement estimate, disputing a payroll error, documenting income for a loan, or verifying benefit elections. Storage is free; regenerating a missing record from a prior employer’s payroll office is not.

2. The anatomy of your LES

Formats vary slightly by payroll provider, but every federal LES is organized into the same handful of blocks. Here’s the map — we’ll walk each one in turn.

3. Identification & pay basics

The top block confirms who and what you’re being paid as. It shows your name and a masked identifier, your pay period and pay dates, and — most usefully — your grade and step, your locality area, and your rate of basic pay. These aren’t just labels; they drive every dollar below. Your grade and step set your base salary, and your locality adjustment (which varies widely by geographic area) can add a substantial percentage on top.

Two things here are worth a periodic glance. First, your step: within-grade step increases happen automatically on a schedule, and this block is where you confirm the raise actually took effect on time — a delayed step increase is a common, correctable error. Second, your rate of basic pay is the number that ultimately matters most for retirement, because your pension is computed on your highest three consecutive years of basic pay, not on your take-home. If you want to see how that flows into your annuity, our guide to the FERS pension calculation connects this line to your future benefit.

Make sure the basics simply match reality: correct grade, correct step, correct locality for where you actually work. Errors up here quietly propagate into everything below, so a quick sanity check when anything changes — a promotion, a move, a reassignment — is time well spent.

4. Earnings: gross pay

The earnings block is your gross pay — everything you earned this period before a single deduction. For most feds the bulk is “regular pay” (your basic pay for the hours worked), with locality pay typically baked into that figure. If you earned anything extra — overtime, night or Sunday differential, hazard pay, a premium — it appears here as its own line, so you can confirm you were paid for it.

This is the number to check first whenever your circumstances change. Got a raise, a promotion, or a step increase? Your gross should reflect it in the corresponding pay period. Worked overtime? It should be itemized. A surprisingly common error is extra time worked that never makes it onto the statement — and if it’s not on your LES, you didn’t get paid for it. The earnings block is your proof, so it’s worth matching against what you actually worked when anything is out of the ordinary.

Keep in mind the distinction that trips people up: gross pay is what you earned; it is not what hits your account. The journey from this number down to your net pay runs through the deductions block — and understanding that journey is the difference between feeling like money vanished and knowing exactly where every dollar went.

5. Deductions: where the money goes

The deductions block is the heart of the LES and the part that most deserves your attention, because it’s where 30 to 40% of your gross disappears — not into a void, but into three buckets: your future, your protection, and your taxes. Every line is either something you’re building, something you’re insuring, or something you owe.

Your future. Your FERS retirement contribution is a small percentage of basic pay (the exact rate depends on when you were hired) that funds your pension — a mandatory deduction, but one buying you a guaranteed lifetime annuity most private-sector workers will never have. Your TSP contribution also lives here (it gets its own section, covered next) and is money moving into your own retirement account.

Your protection. FEHB (health insurance) and FEGLI (life insurance) premiums come out here, along with any FEDVIP dental/vision or FSA elections. These are the deductions most within your control — you choose the plan and tier — so they’re worth revisiting, especially during Open Season. If you’re unsure whether your health tier fits your household, our guide on Self Plus One vs. Family can save real money.

What you owe. Taxes make up the rest and get their own section below. The key mindset for the whole block: these aren’t arbitrary subtractions — they’re the mechanism that turns a paycheck into a pension, coverage, and a squared-away tax bill. Reading them is how you make sure each is doing what you intend.

Alongside each current-period deduction, most statements carry a year-to-date column, and it’s quietly one of the most useful parts of the LES. Your YTD figures let you see the cumulative picture: how much you’ve paid in taxes so far, how much you’ve put into the TSP against the annual limit, how much has gone to health premiums. Glancing at YTD TSP a few times a year is the simplest way to avoid the front-loading trap — if you’re on pace to hit the contribution limit before December, you can ease off and keep the per-pay-period match alive through the end of the year.

6. The TSP section — check this one

If you read only one part of your LES, make it this one, because it’s where you confirm you’re collecting free money. The TSP block shows two distinct things: your own contribution and the agency contributions on top of it. Both matter, and the relationship between them is what you’re verifying.

First, confirm your own contribution is at least 5% of basic pay. Then check the agency side: your agency adds an automatic 1% no matter what, plus a match that brings the total agency contribution to about 5% when you contribute a full 5% yourself — a dollar-for-dollar match on the first 3% and 50 cents on the dollar for the next 2%. Put simply, contribute 5% and the agency contributes 5%; that’s an instant 100% return you should never leave on the table. If the agency figure looks smaller than it should, something is off.

The block also usually shows whether your contributions are going to traditional or Roth TSP, and your year-to-date totals — useful for pacing yourself against the annual limit so you don’t front-load by accident. If you’re weighing which type to fund, Roth TSP vs. Roth IRA lays out the choice. A ten-second glance at this section each pay period is, dollar for dollar, the most valuable habit on this entire list.

7. FEHB, FEGLI & other benefits

Your benefit elections show up as coded deductions, and the codes are worth decoding because a wrong one costs money or coverage. Your FEHB line carries an enrollment code that identifies your exact plan and tier (self only, self plus one, or self and family). After Open Season or a life event, this is where you confirm the change you made actually took effect — a stale plan code is a classic error that has people paying for coverage they meant to drop, or enrolled in the wrong tier for months.

FEGLI, your federal life insurance, appears as its own deduction. FEGLI premiums rise with age, so it’s worth periodically checking what you’re paying against what coverage you actually need — especially as you approach retirement, when the math changes and some options get expensive. Our guide to FEGLI in retirement covers the reduction elections that determine what you pay later.

You may also see deductions for FEDVIP dental and vision, a flexible spending account, an HSA if you’re in a qualifying high-deductible plan, allotments to savings, union dues, or charitable giving. None are complicated individually, but collectively they add up — and the LES is the one place you see them all together. Scanning the list occasionally catches the small recurring deduction you forgot you set up and no longer want.

Two other things surface in this area worth recognizing. If you have an outstanding TSP loan, its repayment appears as a deduction here — useful for confirming payments are being taken as expected. And any allotments you’ve set up — automatic transfers to a savings account, a credit union, or a second bank — show up as their own lines. Allotments are a genuinely handy tool for “paying yourself first” straight from payroll (a great way to fund the cash cushion in your high-yield savings), but they’re also easy to forget, so the LES is where you audit them. To change most of these elections, you’ll go back through the same payroll portal where you read the statement.

8. Taxes withheld

The tax lines show what’s being withheld and sent to the government on your behalf: federal income tax, state income tax (if your state has one), and FICA — Social Security (6.2%) and Medicare (1.45%) — which fund the benefits you’ll draw later. Withholding is driven by the elections on your W-4, so if a refund or a tax bill last year felt way off, this is the block that explains why and the lever you adjust.

A quick reality check is worth doing once a year or after any big change (marriage, a second income, a house). If you’re getting a large refund every spring, you’re lending the government money interest-free all year and could adjust your withholding to keep more in each paycheck. If you owe a lot each April, you’re under-withheld and risking penalties. Either way, the fix is a new W-4, and this block is how you confirm it worked.

One note for planning ahead: the way pay is taxed while you’re working differs from how your income will be taxed in retirement, when pension, TSP withdrawals, and Social Security each get their own treatment. Reading your withholding now builds the habit you’ll want later — our overview of how retirement income is taxed picks up where your working-years W-4 leaves off.

9. Your leave balances

The leave block is the “Leave” half of the Leave & Earnings Statement, and it’s pure earned value — time you’ve banked. It shows, for both annual leave and sick leave, how much you earned this period, how much you used, and your current balance, usually in hours. Federal leave accrues every pay period based on your years of service, so watching these numbers climb is watching a real benefit accumulate.

The line to watch is use-or-lose. Annual leave carries a ceiling (for most employees, 240 hours); anything above that at the end of the leave year is forfeited unless used. Your LES flags how much use-or-lose leave you’re carrying, and ignoring it means literally throwing away paid time off. Plan to spend it down before the deadline — that flagged number is a countdown.

Know how fast you accrue, because it rises with tenure: most full-time employees earn 4 hours of annual leave per pay period in their first three years, 6 hours from three to fifteen years, and 8 hours after fifteen — while sick leave accrues at a steady 4 hours per pay period throughout your career. Your LES may also track other categories depending on your situation: earned compensatory time or credit hours (for those on flexible schedules), court leave for jury duty, and military leave for reservists. Each has its own rules for accrual and expiration, and seeing them itemized here is how you make sure hard-earned time doesn’t quietly vanish.

These balances aren’t just for time off, either — they have real retirement value. Unused annual leave is paid out in a lump sum when you retire, so it converts to cash; our guide to the annual-leave lump-sum payout covers how that works. And unused sick leave is added to your service for computing your pension, effectively boosting your annuity — see sick-leave service credit. Watching these balances is watching two future benefits grow, which is why the leave block deserves more than a passing glance.

10. The 2-minute check every pay period

You don’t need to study the whole document each time — a quick scan of a few key lines catches almost every problem. Make this your biweekly habit:

1. Net pay. Does it look right? A sudden, unexplained change up or down is your first signal that something shifted — a new deduction, a tax change, an error. Start here.

2. Your TSP contribution and the agency match. Are you contributing at least 5%, and is the agency adding its full share? This ten-second check protects free money — the single highest-value line on the statement.

3. Benefit codes. Right after Open Season or a life event, confirm your FEHB tier and any changes actually took effect. Stale codes cost money quietly.

4. Leave balances. Are you accruing what you expect, and is any use-or-lose leave piling up? Catch it while there’s still time to use it.

5. Anything that just changed. After a raise, promotion, step increase, or move, confirm the LES reflects it. Changes are exactly when errors sneak in. Two minutes here is the cheapest financial checkup you’ll ever do — and it feeds straight into your budget, since you can’t plan around a number you haven’t verified.

11. Common LES errors to catch

Payroll systems are complex and errors are more common than people assume. These are the ones that show up most and cost the most if missed.

The shut-off match. By far the most expensive: front-loading TSP contributions, hitting the annual limit early, and losing the per-pay-period match for the rest of the year. It’s visible the moment the agency match drops on your statement — and preventable by spreading contributions across all pay periods.

A stale benefit election. You changed your FEHB plan or tier during Open Season, but the code never updated — so you’re paying for the old plan, or the wrong tier, pay period after pay period. Verify changes took effect the first LES after they should have.

A missing raise or step increase. Within-grade increases and pay adjustments occasionally lag. If your gross didn’t move when it should have, flag it — back pay is recoverable, but only if you notice.

Unpaid overtime or premiums. Extra time worked that never made it onto the statement. If it’s not on the LES, it wasn’t paid — check when you’ve worked beyond the ordinary. When you spot any of these, contact your agency’s payroll or HR office promptly; the sooner an error is caught, the cleaner it is to correct.

When you do find something wrong, document it before you raise it: save the LES showing the problem (and, ideally, an earlier correct one for comparison), note the pay period and the specific line, and take that to your agency’s servicing payroll or HR office rather than trying to fix it informally. Written evidence turns a “my pay looks off” conversation into a specific, provable request, which gets resolved faster and cleaner. This is exactly why saving your statements pays off — the fix for a payroll error is only as easy as your ability to show what it should have been.
