Your LES Is Telling You Something. Most People Never Look.
BLUF (Bottom Line Up Front)
Your Leave and Earnings Statement is a monthly record of every dollar going in and out of your military pay. Most of it is accurate most of the time. But DFAS makes mistakes, and those mistakes compound quietly until you catch them. Knowing six specific fields on your LES is the difference between noticing and not noticing. This post covers those six and tells you exactly when to look.
Most people treat their LES like a terms and conditions page. They know it exists. They've technically agreed to receive it. They have not read it.
Here's the thing. For most months of your career that's probably fine. Your pay hits the account, it looks roughly right, life moves on. I won't pretend that scanning a 70-field government document every 30 days is a good use of your morning.
But there are moments when your LES is the only document that will tell you something went wrong. And because DFAS processes pay for over 2.5 million service members with aging systems and a bureaucratic lag that would make the DMV nervous, errors happen. Wrong BAH rate. Promotion pay not applied. TSP contribution stuck at the old percentage. Allotments that should've stopped six months ago quietly still running. None of these show up as alerts. Nobody calls you. The money just moves differently than it should, and nothing tells you it happened.
Think of your LES as a ledger, not a receipt. A receipt tells you what already happened. A ledger tells you whether it happened correctly.
So here's a practical version of this. Not a field-by-field dictionary of all 70 entries. Just the parts that actually matter, and the moments when you should pull it up.
Where to Find It
Log into myPay at mypay.dfas.mil. Your LES is under "Leave and Earnings Statements" on the left menu. You can pull current and historical statements going back years. Download the PDF version if you want something you can actually read without squinting.
The Six Fields That Matter
1. Base Pay
This should match the official military pay chart for your rank and years of service. It sounds obvious, but promotions don't always process on the right timeline. If you pinned on a new rank and your next LES doesn't reflect the new base pay rate, that gap will eventually reconcile but it can be confusing when it does and it's worth knowing why.
Cross-check your base pay against the 2026 military pay chart at least once after any promotion. Takes 30 seconds.
2. BAH Rate and Type
BAH is one of the more common places errors show up. Two things can go wrong here, and both are worth checking.
First, the rate. BAH is calculated based on your permanent duty station ZIP code and your dependency status. If DFAS has the wrong ZIP on file, or if your dependency status hasn't been updated after getting married or having a child, your BAH will be wrong. Sometimes low, occasionally high. Low means you're owed money and will eventually get it back. High means you'll eventually owe DFAS money you've already spent, which is a worse situation.
Second, the type. Your LES will show either BAH with dependents or without. If you got married and your records haven't caught up, you're leaving money on the table every single month. For a mid-grade NCO or officer, the difference between with-dependent and without-dependent BAH is often $300 to $600 per month depending on location.
A $400/month BAH error that goes unnoticed for six months is a $2,400 correction. If it was an overpayment, that's money you owe back. If it was underpaid, that's money you didn't have when you needed it. The salary calculator lets you verify your expected BAH by rank and ZIP code so you have a number to compare against.
3. Federal Income Tax Withheld (FITW)
This one trips people up after life changes. The amount withheld for federal taxes is driven by your W-4, which you set when you entered service and possibly haven't touched since. Got married? Had kids? Started doing something unusual with allotments? Your withholding might be off.
Too much withheld means a refund at tax time, which feels nice but is just an interest-free loan to the government. Too little withheld means a bill in April, which feels bad regardless of the reason.
If your FITW looks unusually high or low compared to prior months with no obvious explanation, pull up your W-4 on myPay and verify the settings still reflect your situation. It's not complicated, it just requires actually looking.
4. TSP Contribution
Your LES will show the dollar amount going to TSP that pay period, broken out between Traditional and Roth if you're splitting. Two things to verify here.
One: the percentage or flat amount matches what you actually set. TSP elections occasionally fail to apply correctly or don't update as expected after system changes, and a contribution drop that goes unnoticed for a few months is real money.
Two: if you're under the Blended Retirement System, verify you're contributing at least 5% to capture the full government match. The match is 1% automatic plus dollar-for-dollar on your next 3% plus 50 cents on the dollar for the final 2%. Contributing 4% instead of 5% costs you roughly $500 to $1,000 per year in free match depending on your pay grade, every year you're under 5%.
If you want to model where your current contribution rate takes you over time, the TSP calculator runs that projection by rank.
5. Leave Balance
This one matters most when it's about to matter a lot. Your LES shows your current accrued leave balance and your lost leave ceiling (the standard 60-day carryover cap, higher if you have approved Special Leave Accrual from a deployment or other qualifying period). Two moments when you should absolutely look at this number:
Before a PCS. Terminal leave or permissive TDY at the end of an assignment is planned around your balance. Showing up at the conversation with your finance office not knowing your actual accrued days is an avoidable situation.
Approaching separation or retirement. Terminal leave payout at separation is calculated on your base pay at the time you leave. At an O-4 or E-7 level, unused leave days represent real money. You want to know your balance well enough in advance to make intentional decisions about whether to sell it or use it.
6. Deductions (All of Them)
Scroll through the deductions section of your LES and ask yourself if you recognize everything on the list. Allotments in particular tend to get set up and then forgotten. A car payment allotment that stopped automatically drafting from your bank but is still routing through DFAS. A savings allotment from a deployment that's still running. These show up as line items and they keep running until someone tells DFAS to stop them.
This isn't common. But when it happens, it runs quietly until you catch it.
When to Actually Pull It Up
You don't need to audit your LES every month. If you remember nothing else from this post, check it at these moments:
- After a promotion — Verify new base pay rate applied correctly
- After a PCS — Verify BAH ZIP code and rate updated to new duty station
- After getting married or adding a dependent — Verify BAH with dependents rate applied
- After changing your TSP contribution — Verify the new amount appears next pay period
- When starting a new fiscal year (October) — Check your leave balance didn't get cut by the 60-day cap
- Six months before ETS or retirement — Know your leave balance early enough to plan around it
- Any time your deposit looks off — Don't assume. Pull the LES and find the line
For everything in between, you're probably fine.
One More Thing
If you do find an error, the process for correcting it runs through your finance office, not directly through DFAS. Document the discrepancy clearly: what your LES shows, what the correct amount should be, and why. Screenshots help. The correction will usually show up as an adjustment entry on a future LES rather than a separate payment, so you'll want to confirm the fix actually applied when the next statement drops.
Your LES isn't interesting. It wasn't designed to be.
But it is the single source of truth for what the government says it paid you.
And every now and then, that record is wrong.
Knowing where to look takes ten minutes. Catching one mistake can be worth thousands.
