DTS scheduled partial payments can help pay anticipated expenses during an eligible long TDY instead of leaving all settlement until the trip ends. DTMO's authorization guide says the Scheduled Partial Payments section appears on the Accounting page when the trip exceeds 45 days. The schedule uses 30-day intervals. Eligibility is therefore not the same as “any trip lasting 30 days.” DTS Guide 2, section 7.3
These are travel payments, separate from ordinary military pay. They do not remove the need to keep records, monitor your Government Travel Charge Card (GTCC), correct trip changes and submit a final voucher.
Set up the payment plan with the authorization
The September 2026 guide gives this sequence on the Accounting page:
- Ensure the document has the correct line of accounting (LOA); obtain that information from your unit rather than guessing.
- Select Request SPP and review the displayed payment periods and amounts.
- Select Continue after checking the schedule.
DTS calculates the amounts from estimated expenses and itinerary dates. You cannot manually edit SPP amounts or payment dates. DTS Guide 2, section 7.3, printed pages 131–132
Review the schedule with your unit's travel support team. Confirm that the authorization and payment request complete the required approval process. The DTS regulations describe payments based on anticipated expenses following approving-official approval. DTS Regulations, Scheduled Partial Payments
Use a preparation checklist before departure:
- Confirm the official trip length and whether SPPs are available.
- Check the estimated lodging, meal treatment and other expenses.
- Review payment dates and destinations, including the travel-card vendor.
- Verify profile and payment details through official channels.
- Identify the travel-support and Agency Program Coordinator contacts for problems.
A scheduled date is not a promise that funds will be posted to a particular account that same day. Check the actual payment record and card statement.
Keep a simple record while you are away
You can use a private table like this to compare expected and actual activity:
| Period | Estimated eligible expenses | Payment shown in DTS | Payment posted to card or account | Question to resolve |
|---|---|---|---|---|
| First payment period | Your authorization estimate | Date and amount | Date and amount actually posted | Missing or different amount |
| Later payment period | Updated estimate if needed | Date and amount | Date and amount actually posted | Trip or expense change |
Keep this with your personal travel records, not in a class discussion. Do not interpret the whole payment as spendable cash without checking what it covers and where it was disbursed.
The cardholder remains responsible for undisputed travel-card amounts due. Monitor statements even when an SPP is expected, and contact your travel support team and APC promptly if a payment problem threatens the due date. DTMO Cardholders
Update the plan when the trip changes
A shorter trip, different lodging cost or changed meal arrangement can make the original estimate inaccurate. Shortening an authorization deletes SPPs scheduled after the new end date. Changes affecting reimbursable expenses or allowances recalculate future SPPs, and an extension can add payments. DTS cannot change an SPP already in SUBMITTED or PAID status. Review the result instead of assuming an amendment fixes a payment already sent. DTS Guide 2, section 7.3
Ask your travel office to follow the SPP-specific steps when amending the document. DTMO's amendment guidance includes de-scheduling SPPs before making changes; coordinate the update, replacement schedule and approval rather than only editing dates and walking away. Making Changes to DTS Documents, special considerations for SPPs and advances
If a payment does not arrive
Start by identifying where the process stopped:
- Is the eligible trip and payment schedule present in the document?
- Has the necessary approval completed?
- Does DTS show a payment status or error?
- Which destination should receive the funds?
- Does that destination show the payment posted?
- Has an amendment or funding issue changed the schedule?
Provide those facts privately to travel support. Avoid creating duplicate documents or changing banking details merely because a payment is late. If the trip crosses October 1, mention that: DTMO's fiscal-year guide describes accounting-system shutdowns and crossover considerations that can affect payment processing. Processing Authorizations for the New Fiscal Year, Chapter 6
The final voucher still matters
Submit the final travel voucher within five working days of return, update the actual trip and expenses, and review previous payments and disbursement details. An SPP was based on anticipated costs; the final settlement must reconcile the actual entitlement and payments already made. Do not expect a second payment of the entire trip estimate.
