A Government Purchase Card, or GPC, is a charge card issued to federal employees so they can buy supplies and services for the government without running each transaction through the full contracting process. It operates under GSA SmartPay, the largest government charge card program in the world, and as of October 2025 the standard micro-purchase threshold sits at $15,000 for most goods. The Office of Management and Budget governs the program’s internal controls through Circular A-123, Appendix B, which requires every executive agency to maintain risk management policies, separation of duties, and annual certifications over its charge card accounts.1Office of Management and Budget. OMB Circular A-123 Appendix B – A Risk Management Framework for Government Charge Card Programs
What the Card Is For
Agencies use the GPC to buy commercially available goods and services needed for daily operations: office supplies, IT equipment, repair parts, routine services. Before purchase cards existed, even a small order of printer paper could require its own purchase order, vendor registration, and payment cycle. The GPC collapses that into a single transaction, cuts administrative costs, and gets small businesses paid through the banking network almost immediately rather than after weeks of waiting for a government check.
The card is both a purchasing tool and a payment method. Under FAR 13.301, the governmentwide commercial purchase card may be used to make micro-purchases, place orders against existing contracts, and pay for items ordered through other simplified acquisition methods.2Acquisition.GOV. 48 CFR 13.301 – Governmentwide Commercial Purchase Card For transactions at or below the micro-purchase threshold, the GPC is the preferred procurement method because it eliminates the need to set up individual vendors in complex federal payment systems for low-value buys.3Acquisition.GOV.

Cardholders also carry sustainability obligations. FAR Part 23 directs agencies to prioritize multi-attribute sustainable products and services, so cardholders should choose recycled, biobased, or energy-efficient options when they are available and meet the mission need.4US EPA. Buying Green for Federal Purchasers It is a regulatory requirement, not a suggestion, and it applies to routine card transactions.
How Much a Cardholder Can Spend
The micro-purchase threshold is the dollar ceiling below which a cardholder can buy supplies or services without obtaining competitive quotes. As of October 1, 2025, the standard threshold is $15,000 for most acquisitions. During contingency operations it rises to $25,000, and for defense-agency support purchases it goes to $40,000.5Acquisition.GOV. Threshold Changes – October 1st, 2025 Categories like construction have historically carried lower thresholds, so cardholders should check the current FAR 2.101 definitions before assuming the general limit applies to every purchase type.
On top of the governmentwide thresholds, every cardholder operates under two agency-imposed limits. The single purchase limit caps any one transaction at a set amount based on the cardholder’s delegated authority. The monthly cycle limit caps total spending across all transactions during a billing cycle, set according to the department’s mission needs and anticipated volume. Someone who mostly orders office supplies might have a $3,000 single-purchase limit with a $25,000 monthly cap, while a cardholder buying specialized equipment could carry substantially higher limits. Billing officials and program coordinators recommend these limits based on historical spending and adjust them when requirements change.6Acquisition.GOV. AFARS Chapter 2 – Program Organization, Roles, and Responsibilities
What Cardholders Cannot Buy
The GPC is strictly limited to official, mission-related purchases. Using it for personal, family, or household expenses is a violation that can end a career. Several less obvious restrictions trip cardholders up regularly.
Split purchases are prohibited under FAR 13.003(c)(2). Breaking a single known requirement into smaller transactions to stay under the micro-purchase threshold is not allowed. The test is what the cardholder knew at the time of purchase: if the full requirement costs $20,000, you cannot place two $10,000 orders.7Acquisition.GOV. 48 CFR 13.003 – Policy8Acquisition.GOV. AFARS 14-5 – Split Purchases Requirements over the threshold go to a contracting officer.
Third-party payment processors like PayPal, Venmo, Square, Stripe, and Zelle are treated as high-risk. They are only authorized when unavoidable, and cardholders must document why no other vendor was available.9Department of Defense. Purchase Cards – Frequently Asked Questions Individual goodwill gestures such as Christmas cards cannot be bought with the GPC. And a GPC cannot be issued to a contractor under any circumstances.
Some cardholders are also authorized to write convenience checks against their GPC account, but the rules are tighter than for card transactions. The micro-purchase threshold for convenience checks is half the standard open-market threshold, and checks cannot be used for employee reimbursements, cash advances, cash awards, travel payments, or recurring payments. There is no bank dispute process for checks, so problems have to be resolved directly with the merchant.10Acquisition.GOV. AFARS Chapter 10 – Convenience Checks
Sales Tax and Shipping
All GSA SmartPay purchase cards are centrally billed accounts, meaning the federal government pays the bank directly. States are required to honor sales tax exemption for centrally billed accounts. Cardholders can confirm this status by checking the sixth digit of the card’s bank identification number: if it is 0, 5, 6, 7, 8, or 9, the account is government-paid and generally exempt from state sales tax. The exemption covers state sales tax specifically. Hotel-specific taxes, local municipal fees, and other non-sales-tax charges may still be assessed unless the state has extended the exemption to cover them.11GSA SmartPay. Frequently Asked Questions
Items purchased with a GPC must be shipped to official government addresses. Shipping to personal residences or commercial addresses requires advance approval from the program coordinator. For shipments outside the continental United States, the cardholder coordinates with the local logistics or transportation office to determine whether commercial shipping is available; when it is not, the shipment enters the Defense Transportation System and the vendor must receive a Military Shipping Label with a final in-country destination address.12Acquisition.GOV. AFARS 6-2 – GPC Purchasing Process
Who Gets a Card
Prospective cardholders go through a defined appointment process before they are authorized to spend government funds. Training comes first. Within the Department of Defense, the mandatory course is CLG 0010, required before assuming any GPC role and renewed every two years.13Department of Defense. Purchase Cards – Training Civilian agencies have their own training requirements, but the principle is the same across the federal government: no one touches a GPC without completing procurement ethics and card usage training. Most agencies add supplemental training on internal workflows and local policies.
After training, DoD employees complete DD Form 577, which formally appoints them as accountable officials. The form acknowledges the cardholder’s pecuniary liability, meaning they accept personal financial responsibility for public funds under their control.14Department of Defense. DD Form 577 – Appointment/Termination Record – Authorized Signature The application also requires accurate accounting data so the card maps to the correct budget lines.
A GPC does not affect the cardholder’s personal credit, and there is no credit check to be appointed. If a cardholder makes unauthorized purchases and is found financially liable, however, that debt could eventually hit their personal credit if left unpaid.
Oversight and Consequences of Misuse
Every GPC transaction runs through a layered review structure. The cardholder reconciles transactions against receipts and documentation. The billing or approving official then reviews and certifies the billing statement. OMB Circular A-123 requires this reconciliation to happen no later than 30 days after the end of the billing cycle.1Office of Management and Budget. OMB Circular A-123 Appendix B – A Risk Management Framework for Government Charge Card Programs Many agencies impose tighter timelines; the Army, for example, requires billing officials to certify statements within five business days of cycle end.6Acquisition.GOV. AFARS Chapter 2 – Program Organization, Roles, and Responsibilities
Beyond manual review, agencies deploy automated data mining tools that scan thousands of transactions for patterns suggesting unauthorized use or policy violations. When a business rule is broken, the system automatically generates a case for review.15Acquisition.GOV. AFARS 11-4 – Data Mining Case Review and Closure The Agency/Organization Program Coordinator sits above both layers, running periodic audits to verify that required paperwork and receipts are maintained for the legal retention period.16GSA SmartPay. Agency/Organization Program Coordinator Responsibilities
Using a GPC for anything other than official government business is treated as attempted fraud against the United States. Consequences scale with severity. Administrative actions range from reprimand and counseling to card cancellation, suspension, or termination of employment. The cardholder is personally liable to the government for the amount of any non-government transaction, and if they let someone else use the card, they bear liability for any unauthorized charges that result. Under 18 U.S.C. § 287, misuse can result in fines, imprisonment, or both, and military members face additional exposure to court martial under 10 U.S.C. § 932.17GSA SmartPay. Lesson 11 – Misuse/Abuse and Fraud Even an accidental swipe of the GPC instead of a personal card triggers a formal review process that requires documented corrective action.
