GTCC Overview and Authorities

Start Here If You Are New to GTCC

The Government Travel Charge Card (GTCC) is the DoD-mandated payment instrument for official travel. The card is issued by Citibank under the GSA SmartPay program. Two types. Individually Billed Account (IBA), the most common, issued to the Marine in the Marine's name. The Marine pays the bill and is reimbursed by the Government through DTS. Centrally Billed Account (CBA), managed by the unit, used for travelers who do not have an IBA. Each Marine cardholder works with an Agency Program Coordinator (APC), who is the local point of contact for GTCC issues. GTCC use is mandatory for official travel per DoDI 5154.31DoDI 5154.31 Vol 4 unless an exemption applies. The Marine Corps program is implemented through MCO 4600.40CMCO 4600.40C, with recent expansion to entry-level Marines via MARADMIN 478/24MARADMIN 478/24.

Why the GTCC Exists

The GTCC reduces the Marine's out-of-pocket exposure for official travel. Before the GTCC, Marines often used personal funds and waited for reimbursement, creating financial hardship for short-notice or extended TDY. The Government-contracted card.

• Provides Government-negotiated rates with hotels, rental car agencies, and other travel merchants.
• Reduces personal financial risk for the Marine.
• Streamlines the travel claim process through DTS integration.
• Supports auditability and oversight of official travel spending.

Two Account Types

Individually Billed Account (IBA)

The most common type. The card is issued in the Marine's name. The Marine.

• Charges all official travel expenses to the IBA during travel.
• Receives the monthly billing statement from Citibank.
• Pays Citibank directly (typically via split disbursement from the travel reimbursement).
• Is personally responsible for payment of all undisputed amounts.

The Cardholder Reference Edition of the GTCC Regulations governs IBA cardholder responsibilities.

Centrally Billed Account (CBA)

The card is issued to the unit (not to an individual Marine). The unit pays Citibank directly. CBA is used for.

• Travelers who do not have an IBA (e.g., new accessions awaiting card issuance).
• Group travel coordinated through the unit.
• Reservation-only payment instruments where the traveler does not need card-in-hand.

CBA usage is coordinated through the unit's Defense Travel Administrator (DTA) or APC.

JTR Chapters 2-5

Marines locate their APC through the chain of command, the HR or Admin office, or the local travel help desk.

TECOM HL3 APC

Per MARADMIN 478/24MARADMIN 478/24, TECOM established Hierarchy Level 3 (HL3) APC oversight for entry-level Marine cardholder accounts under Training Command schoolhouse hierarchies. Entry-level Marine accounts default to these HLs.

Commander or Supervisor

Validates credit limit increase requests, mission-critical status changes, and references on suspension or cancellation actions. The commander signs Page 11 entries for documented misuse.

AO and Reviewing Official

Approves the travel voucher in DTS, ensuring split disbursement amounts will fully pay the GTCC bill.

Card Vendor (Citibank)

The DoD GTCC contract is held by Citibank under the GSA SmartPay program. Cardholders.

• Receive cards bearing the Marine's name and a 16-digit account number.
• Manage accounts through CitiManager (web portal and mobile app).
• Contact 24/7 customer service at 1-800-200-7056 (CONUS) or 1-757-852-9076 (toll-free OCONUS).

Citibank issues both Standard and Restricted IBAs based on the FICO credit evaluation. The Standard vs Restricted IBAs leaf covers the distinction in detail.

DTS Integration

The GTCC is integrated with the Defense Travel System (DTS).

Profile-Linked GTCC

The cardholder enters the GTCC information into the DTS profile. DTS uses the GTCC to.

• Reserve airfare through CTOs and the City Pair Program.
• Reserve rental cars at the Government rate.
• Book lodging at GSA per diem rates.

Split Disbursement

DTS automatically calculates a split disbursement that pays the GTCC bill directly from the travel reimbursement. Split disbursement is mandatory DoD-wide. The GTCC Split Disbursement leaf covers the framework.

Web Portal

Accessible at https://home.cards.citidirect.com/. Cardholders.

Auto-Enrollment Since March 2020

Cardholders who applied after March 2020 have CitiManager accounts automatically created during card issuance. Cardholders issued cards before March 2020 must self-enroll at CitiManager.

Where GTCC Fits in the Marine's Travel Workflow

1. Marine receives PCS or TDY orders.
2. Marine confirms the GTCC is active and the account profile is current.
3. Marine charges authorized travel expenses to the GTCC.
4. Marine submits the travel voucher in DTS within 5 working days of return (TDY) or report (PCS).
5. DTS processes the voucher with split disbursement to Citibank.
6. Marine verifies split disbursement covered the full bill, makes additional manual payment if shortfall.
7. Cardholder retains receipts and reconciles the LES against the DTS reimbursement.

Common Questions Marines Ask

What is the difference between IBA and CBA?

IBA is issued to the Marine personally. The Marine pays Citibank and is reimbursed by the Government. CBA is issued to the unit. The Government pays Citibank directly. CBA is for travelers without an IBA or for group travel.

When am I required to use the GTCC?

Per DoDI 5154.31DoDI 5154.31 Vol 4, GTCC use is mandatory for official travel unless an exemption applies. Common exemptions are payments to vendors that do not accept cards or expenses where the GTCC is operationally impractical.

Who is my APC?

Ask the chain of command, the unit S-1, or the local travel help desk. The APC is the primary point of contact for all GTCC issues.

How do I get a GTCC?

Through the Apply for a GTCC process. SOU, Travel Card 101 training in TraX, application via the APC, and (if applicable) DD Form 2883DD Form 2883 alternate credit evaluation.

What happens if I do not pay my GTCC bill on time?

Late payment triggers escalating actions. 60-day delinquency typically results in suspension. Continued non-payment leads to cancellation and potential UCMJ action. The GTCC Misuse, Suspension, and Cancellation leaf covers the framework.

Can I use my GTCC for personal expenses?

No. Personal use is prohibited per DoDI 5154.31DoDI 5154.31 Vol 4 and MCO 4600.40CMCO 4600.40C. Misuse triggers Page 11 entries, suspension, and possible UCMJ action.

Can I use my GTCC during leave or PTAD?

No. Per MARADMIN 478/24MARADMIN 478/24 paragraph 3.E.4, use of the GTCC during Permissive TAD or leave status is prohibited.
