Why DTS Denies TDY Advance Pay Requests
Military travel paperwork has gotten complicated with all the system errors and policy confusion flying around. I’ve watched soldiers nearly lose their minds over this exact scenario — orders are approved, the trip is locked in, and then the advance request just dies. Either the button won’t process or DTS spits back some vague error that tells you absolutely nothing useful.
Here’s the thing though: the denial is almost never random. Four specific reasons account for virtually every rejected advance request. Know which one you’re dealing with and you cut your fix time in half — at least if you catch it early enough.
Your orders aren’t fully approved yet. This one causes more headaches than anything else. DTS won’t allow an advance request until the orders have cleared every single authorization step. Sitting in “pending approval”? Amended and cycling back through the chain? The system blocks the advance — full stop. It won’t let you request payment on travel that hasn’t been officially greenlit. Log into DTS and look at the main status field. If it doesn’t say “Approved” — clean, no qualifiers — that’s your problem right there. Wait for the full cycle to complete before you try again.
You’re requesting the advance too close to your departure date. Federal travel regulations require advance requests at least seven to ten calendar days out. Most military units run on the seven-day rule. Trip is in four days and you’re just now clicking the button? DTS denies it. That’s policy enforcement, not a glitch. And no — you cannot override it. Once that window closes, it’s closed.
You requested more than the authorized percentage. Military TDY advances cap at 85 percent of your estimated trip cost. Some organizations only authorize 75 percent. Request 90 percent and DTS rejects it outright, forcing you to start over at the correct number. The error message rarely spells this out, which is why half the people who hit this problem assume the system itself is broken. It isn’t. It’s just enforcing the ceiling.
Your Authorization Officer doesn’t have advance pay authority enabled. AOs need specific permissions inside DTS to approve advance requests. Those permissions expire. They get misconfigured. The AO rotates out and nobody updates the delegation. Whatever the reason, when the permissions aren’t right, your request just hangs in “pending AO approval” indefinitely. This one requires a direct call to your unit DTS Help Desk — there’s no workaround you can run yourself.
Check These Three Things Before Doing Anything Else
Before you escalate to finance or start hunting for manual workarounds, run through this quick pre-check. Probably should have opened with this section, honestly — it solves the problem for most people in under five minutes.
Step One — Confirm Your Orders Are Fully Approved
Log into DTS. Pull up your TDY orders. Look at the status field — it should say “Approved.” Nothing else. Not “approved pending amendment,” not “routing for approval.” Just approved. If it says anything else, stop. Don’t submit the advance request yet. Wait for the chain to finish. Usually takes one to three business days. Once that status reads clean, the advance request option will actually work.
Step Two — Verify You’re Within the Advance Request Window
Open your orders and find the departure date. Count back seven days. That date is your hard deadline. If today falls after that date, DTS will deny any advance you submit — no exceptions. At that point you’re into manual fallback territory, which I cover in the next section. Still inside the seven-day window? Move on to step three.
Step Three — Confirm Your AO Has the Right Authority
Call your unit DTS Help Desk or contact your AO directly. Ask specifically whether advance pay authority is currently active on their account. Don’t assume it is. If it’s not enabled, that’s a DTS administration problem — not your fault, not your AO’s fault necessarily, just a permissions issue. Your help desk can usually fix it within the same day. Once it’s corrected, the advance processes normally.
How to Request TDY Advance Pay Outside of DTS
Rejected by the system with no time left on the clock? The manual advance process exists for exactly this scenario.
Call your unit finance office directly. Tell them DTS denied your advance request and you’re departing within the advance window — they’ll either run it through their internal system or hand you a DD Form 1351-2 and walk you through it. That form has been around forever. It works.
Bring these items to your finance office:
- A printed copy of your approved TDY orders
- Your estimated trip costs broken down by category (meals, lodging, rental car)
- Your departure and return dates
- The percentage of the estimated cost you’re requesting as an advance (typically 75–85 percent)
Be specific with your numbers. Don’t say “around $1,500.” Say “$1,487 for four nights’ lodging in San Antonio at the GSA rate, $320 for meals at the per diem rate, $180 for a compact rental car.” Finance calculates the advance amount from those figures — vague estimates slow everything down.
Manual processing takes longer. Budget three to five business days instead of the usual one to two. The money doesn’t hit your account the same way a system-processed advance does. There’s also a paper trail that has to be reconciled later, which adds a step when you submit your post-trip voucher. It works — but don’t start this process the day before you leave. You won’t make it in time.
What to Do If Finance Says No Advance Is Authorized
Sometimes the denial has nothing to do with a technical glitch. It’s just policy. Short trips — usually anything under four or five days, depending on command — often don’t qualify for an advance. Some units don’t authorize advances for local TDY at all. If finance gives you that answer, that’s the final answer. There’s no appeal path worth pursuing.
Your fallback is the government travel card. The GTC exists for exactly this purpose — fronting travel expenses when an advance isn’t on the table. Active GTC? Use it for lodging, rental cars, and incidentals. The card company bills the government directly. You don’t carry the cost out of pocket.
No GTC? Request one immediately. Processing runs one to two weeks. Trip is sooner than that? You’re funding it yourself and claiming full reimbursement on your voucher after you return. Yes, that’s a cash flow problem. Yes, it’s genuinely frustrating. But that’s the reality when the advance isn’t authorized and a GTC isn’t available.
GTC blocked or hitting spending restrictions? Call your unit travel card coordinator the same day — not tomorrow, the same day. They can often lift temporary blocks or bump limits for approved TDY travel. I’m apparently bad at asking for help and learned this lesson the hard way — ended up charging about $600 to a personal Visa because I waited too long to make that call. Don’t make my mistake.
After the Trip — Reconciling an Advance on Your Voucher
You got the advance. Now you have to account for it. When you submit your post-trip travel voucher in DTS, the system asks for the advance amount you received. Enter it correctly. If the advance was $1,200, enter $1,200 — not an approximation, not a rounded number. Enter the wrong amount and your reimbursement calculation breaks. The government overpays you. That overpayment becomes a debt. You repay it. Nobody wants that.
Reconcile your actual trip costs against what you received. Spent less than the advance covered? You repay the difference. Spent more? The government reimburses the balance. Keep every receipt organized before you even get home — DTS will ask for them. Submit the voucher within five business days of returning. It takes maybe twenty minutes. Don’t let it sit on your to-do list for two weeks.
