GTCC Split Disbursement

Start Here If You Are New to Split Disbursement

Split disbursement automatically pays your GTCC bill directly from your travel reimbursement before any remaining funds reach your personal bank account. Mandatory DoD-wide for all GTCC cardholders. When you submit your voucher in DTS, the system calculates a split disbursement amount based on your GTCC charges and sends that amount to Citi. The remainder goes to your personal bank account. If the calculated split disbursement is short of your actual GTCC bill (for example, charges posted after your voucher submission), you manually adjust the amount in DTS or submit a separate payment to Citi. Per DoDI 5154.31DoDI 5154.31 Vol 4, MCO 4600.40CMCO 4600.40C, and DTS configuration.

What Split Disbursement Is

Split disbursement is the DoD-mandated mechanism for paying the GTCC bill directly from the travel reimbursement.

The Problem It Solves

Without split disbursement, the entire travel reimbursement deposits into the cardholder's personal bank account. The cardholder is responsible for transferring the GTCC charges to Citi separately. Late or missed transfers result in delinquency, suspension, and potential UCMJ action.

The Solution

DFAS splits the reimbursement at the source. The GTCC portion goes directly to Citi. The remainder (covering personal expenses like meals or POV gas paid in cash) goes to the cardholder's bank.

DoD-Wide Mandate

Per DoDI 5154.31DoDI 5154.31 Vol 4 and MCO 4600.40CMCO 4600.40C, split disbursement is mandatory for ALL DoD personnel using a GTCC. This is not optional.

MARADMIN 478/24 Reinforcement

Per MARADMIN 478/24MARADMIN 478/24 paragraph 3.E.2, ELT cardholders are explicitly directed that split disbursement of amounts charged to the GTCC is required and should be annotated on any documentation submitted for reimbursement.

How DTS Calculates the Split

When you create the travel voucher in DTS, the system.

1. Pulls the GTCC transactions from the Citi system that match the trip date range.
2. Categorizes each transaction (lodging, transportation, meals, etc.).
3. Calculates the total GTCC charges associated with the trip.
4. Sets the default split disbursement amount equal to the total GTCC charges.
5. Routes the remainder of the reimbursement to your personal bank account.

Where Split Disbursement Appears in DTS

In the voucher, navigate to.

• "Payment Totals" or "Reimbursable Allowances" section.
• Find the line item showing the split between GTCC and EFT (electronic funds transfer to personal bank).

Default vs Manual

DTS pre-populates the split based on the linked GTCC transactions. The cardholder reviews and confirms or manually adjusts.

Verifying the Split Disbursement Amount

Before submitting the voucher, verify the split disbursement covers your full GTCC bill.

Step 1. Pull Your CitiManager Statement

Log in to CitiManager. Identify the total balance for the trip period.

Step 2. Compare to DTS Split

In DTS, view the Payment Totals section. Compare the split disbursement amount to the CitiManager balance.

Step 3. Manually Adjust if Short

If the DTS split disbursement is LESS than your CitiManager balance.

• Charges may have posted after the voucher was created (not yet linked).
• Older charges from a prior trip may still be unpaid.
• Adjustments may be needed for partial-month billing cycles.

Manually increase the split disbursement amount in DTS to cover the full balance.

Step 4. Submit With Confidence

After adjustment, submit the voucher. The AO routes the voucher for approval. DFAS processes the split disbursement and the remainder.

Funds Flow

The funds flow as follows.

1. Marine submits voucher in DTS.
2. AO approves voucher.
3. DTS routes voucher to DFAS for processing.
4. DFAS issues the disbursement (typically 3-5 business days).
5. DFAS sends the split disbursement amount directly to Citi.
6. DFAS sends the remainder to the Marine's personal bank account via EFT.
7. Citi posts the split disbursement payment to the GTCC account.
8. Marine verifies the payment posted in CitiManager.

Posting Timeline

• DFAS to Citi. 1-2 business days.
• Citi posting to account. 1-2 business days after receipt.

Total time from voucher approval to GTCC payment posting is approximately 5-9 business days.

What Happens if Split Disbursement Is Short

If the split disbursement does not fully pay the GTCC bill.

Reason 1. Charges Posted After Voucher Submission

Late-posting charges (e.g., a hotel folio that finalized after the trip end) are not included in the DTS calculation. The Marine pays the shortfall manually through CitiManager or by check.

Reason 2. Voucher Rejected or Reduced

If the AO reduces the reimbursement amount (e.g., disallows a non-allowable expense), the split disbursement is reduced proportionally. The Marine pays the difference manually.

Reason 3. Multiple Trips With Overlapping Charges

When multiple trips overlap, the system may not split charges optimally. The Marine reviews and consolidates payments.

How to Pay the Shortfall

• Through CitiManager online payment from a linked bank account.
• By mail to the Citi standard or overnight payment address with the remittance slip and account number on the check.

The Manage Your GTCC Account leaf covers payment methods.

What Happens if Split Disbursement Exceeds the GTCC Bill

If the split disbursement amount is HIGHER than the actual GTCC bill (rare).

Credit Balance

Citi credits the difference to the GTCC account as a credit balance.

Refund or Apply

The Marine can.

• Leave the credit on the account to apply to future charges.
• Request a refund check from Citi.

Credit balances on a GTCC are uncommon and typically self-resolve within a billing cycle or two.

Annotating Split Disbursement on Reimbursement Documents

Per MARADMIN 478/24MARADMIN 478/24 paragraph 3.E.2, ELT cardholders annotate split disbursement on any documentation submitted for reimbursement. The annotation.

• Confirms the cardholder understands and is using split disbursement.
• Provides a reference for the AO and DFAS during voucher review.
• Supports audit trails for misuse investigations.

For non-ELT Marines, the DTS system already records the split. No separate annotation is required unless the unit's local procedures direct otherwise.

Split Disbursement and On-Time GTCC Payment

Split disbursement is the primary on-time payment mechanism for most cardholders. The framework.

• Reduces the risk of missed payment due to oversight.
• Removes the cash-flow gap between voucher reimbursement and GTCC bill payment.
• Supports the 60-day delinquency suspension threshold by automating payment.

Cardholders Who Do Not Submit Timely Vouchers

Marines who delay voucher submission risk delinquency on the GTCC bill before the split disbursement processes. The Travel Vouchers and Reimbursement page covers the 5-working-day voucher submission rule.

Cardholders With Recurring TDY

Marines with rapidly cycling TDY may have GTCC charges from one trip posting after the voucher for that trip is approved. Manually adjust split disbursement on subsequent vouchers to capture lagging charges.

Verifying Split Disbursement After Voucher Approval

After the voucher is approved.

1. Wait 3-5 business days for DFAS to process.
2. Log in to CitiManager.
3. Verify the split disbursement payment posted (look for a payment matching the DTS amount).
4. Check the LES on MyPay to confirm the EFT remainder posted to your personal bank account.
5. Reconcile the total reimbursement (split + EFT) against the DTS-approved amount.

If the split disbursement did not post within 9 business days, contact Citi customer service or DFAS Marine Corps Pay.

Common Questions Marines Ask

Is split disbursement optional?

No. Split disbursement is mandatory DoD-wide per DoDI 5154.31DoDI 5154.31 Vol 4 and MCO 4600.40CMCO 4600.40C. ELT cardholders have the requirement explicitly reinforced in MARADMIN 478/24MARADMIN 478/24.

How does DTS calculate the split disbursement amount?

DTS pulls GTCC transactions from Citi for the trip date range, sums them, and sets the split equal to the total. The cardholder verifies and manually adjusts if needed.

What if my split disbursement does not cover my full GTCC bill?

Pay the shortfall through CitiManager online payment or by mail to the Citi standard or overnight payment address. Always include the remittance slip and account number on the check.

How long does it take for split disbursement to post?

Approximately 5-9 business days from voucher approval. DFAS processes in 3-5 days. Citi posts within 1-2 days after receipt.

What happens if my split disbursement is more than my GTCC bill?

Citi credits the excess to your GTCC account as a credit balance. You can leave it on the account or request a refund.

Where do I find the split disbursement amount in DTS?

In the voucher, navigate to Payment Totals or Reimbursable Allowances. The split between GTCC and EFT displays.

Can I turn off split disbursement?

No. Split disbursement is mandatory. Disabling or circumventing it is grounds for misuse documentation.

What if I forgot to adjust the split and the bill went unpaid?

Pay the shortfall immediately through CitiManager. Late payment may already be reflected in the account. Contact your APC to flag the situation and avoid 60-day suspension thresholds.
