Government Purchase Card (GPC): Rules, Limits, and Prohibited Items

The Government Purchase Card (GPC) is the federal government’s own version of a procurement card — a charge card issued to individual federal employees under the General Services Administration’s GSA SmartPay program and used to make small-dollar purchases directly from a vendor, without routing every transaction through a purchase order or a contracting officer. If your institution receives federal grant or contract funds and issues its own institutional purchasing card (P-card) to staff, that is a related but legally distinct instrument — see the note on how the two differ, below.

This guide covers what the GPC actually is, who can hold and approve one, current purchase limits, the rules that govern its use, and the categories of purchase that are restricted or prohibited — written for federal agency purchase-card program coordinators, approving officials, and cardholders working in research, laboratory, or intramural-science settings (NIH intramural programs, VA medical/research facilities, USDA Agricultural Research Service, military and DOE national laboratories, and similar).

What Is the Government Purchase Card (GPC)?

The GPC is the purchase-card product within GSA SmartPay, GSA’s governmentwide contract vehicle with commercial card-issuing banks that also covers travel cards, fleet cards, and integrated cards used across federal agencies. Federal agencies issue GPCs to designated employees so they can buy routine, low-dollar supplies and services — lab consumables, small parts, subscriptions, minor equipment, conference registrations within policy — at the point of sale, instead of generating a requisition and waiting on a contracting officer for every purchase under the micro-purchase threshold.

The GPC program is governed by a layered set of authorities: the Federal Acquisition Regulation, specifically FAR Subpart 13.3 (Simplified Acquisition Procedures) and FAR 13.301, which authorizes the governmentwide commercial purchase card as a method of purchase and as a method of payment; OMB Circular A-123, Appendix B (“Improving the Management of Government Charge Card Programs”), which sets the internal-control baseline every agency’s charge card program must meet; and each agency’s own implementing purchase-card regulation, which fills in agency-specific dollar limits, approval chains, restricted-merchant lists, and training requirements. Because that last layer varies by agency, the exact single-purchase limit, monthly limit, and prohibited-item list a given cardholder operates under always traces back to their own agency’s policy, not to a single governmentwide number.

Who Is Involved: Cardholder, Approving Official, A/OPC

Three roles structure every GPC program:

• Cardholder — the individual federal employee to whom the card is issued. The card is non-transferable; only the named cardholder may use it, and using someone else’s GPC is itself a program violation regardless of what was purchased.
• Approving Official (AO) — the cardholder’s designated supervisor or manager who reviews and certifies the monthly statement, confirming each transaction was a legitimate, authorized government purchase before it is certified for payment. An AO typically oversees a limited number of cardholders so review stays meaningful rather than a rubber stamp.
• Agency/Organization Program Coordinator (A/OPC) — the administrator (or team) who runs the program at the agency or sub-agency level: issuing and closing cards, setting or adjusting limits within delegated authority, maintaining the restricted-merchant-category-code (MCC) list, running required refresher training, and serving as the point of contact for the card issuer and for internal/external audit.

This three-role separation — the person who buys, the person who reviews the buy, and the person who administers the program — is the core internal control OMB Circular A-123 Appendix B is built around, and it is the first thing an internal or GAO/agency IG audit checks when a charge-card program is reviewed.

Government Purchase Card Limits

Every GPC carries two dollar limits, both set by the issuing agency (through the A/OPC, within any ceiling the agency’s own policy allows) and both enforced electronically by the card system, not just on paper:

• Single purchase limit — the maximum dollar amount for any one transaction. For most cardholders this is set at or below the federal micro-purchase threshold, which stands at $15,000 as of the October 1, 2025 inflation adjustment to federal acquisition thresholds (up from $10,000; this figure is defined in the FAR and adopted by reference in 2 CFR 200.1 for federal-award purposes, so it applies across both direct federal purchasing and federal-award-funded institutional purchasing). Some agencies authorize higher single-purchase limits for specific cardholders or circumstances — for example, designated cardholders supporting contingency, emergency, or overseas operations may be authorized well above the standard micro-purchase threshold under agency-specific delegations.
• Monthly (billing cycle) limit — the maximum total spend allowed across the statement period, set independently of the single-purchase limit and typically calibrated to the cardholder’s actual purchasing volume rather than a default maximum.

Limits are not a suggestion cardholders work around with multiple smaller transactions. Splitting a single requirement into multiple purchases specifically to stay under the micro-purchase threshold or a cardholder’s purchase limit — commonly called split purchasing or purchase splitting — is treated as a serious violation under FAR and agency purchase-card regulations, precisely because it defeats the competition and documentation requirements the threshold exists to trigger. It is one of the most common findings in GPC program audits.

Government Purchase Card Rules

Beyond the dollar limits, a working GPC program runs on a consistent set of operating rules:

• Purchases must be for an authorized government purpose and within the cardholder’s delegated authority — the card is not a general-purpose office account, and purchases outside the cardholder’s assigned commodity or service area are not authorized even if within dollar limits.
• Reasonable price and, where applicable, competition still apply. Micro-purchases are exempt from formal competitive solicitation requirements, but cardholders are still expected to consider price reasonableness and, where practical, rotate among qualified sources rather than defaulting to the same vendor for every purchase — and, where an agency has designated required sources (such as mandatory federal supply schedules or specific socio-economic set-aside programs), those requirements still apply to card purchases.
• Every transaction needs supporting documentation — typically a receipt or invoice showing what was bought, the business purpose, and (for research settings) the funding source or project charged — retained per the agency’s records schedule and available for the approving official’s monthly review and for audit.
• Monthly statement certification is mandatory and time-bound. Cardholders reconcile their own statement against retained documentation, and the approving official certifies it within the agency’s required window; certification is what authorizes the government to pay the card issuer.
• Mandatory periodic training and, in most agencies, periodic re-certification are conditions of keeping the card, not one-time onboarding steps.
• Convenience checks, where an agency’s card product includes them, are subject to tighter restrictions than card-present or card-not-present purchases and are typically reserved for vendors who cannot accept a card at all.

Government Purchase Card Prohibited Items List

No single governmentwide list exhaustively covers every prohibited item — each agency’s implementing regulation defines its own restricted-purchase and prohibited-merchant-category-code list, and A/OPCs configure those restrictions directly into the card system. That said, the categories below are prohibited or tightly restricted under FAR, OMB Circular A-123 Appendix B, and virtually every agency’s implementation, and are the categories every GPC audit checks first:

• Cash advances, outside narrowly authorized convenience-check circumstances.
• Personal purchases of any kind — including using the card for a personal item with intent to reimburse the government, which is treated as misuse regardless of intent to repay.
• Gifts, gift cards, and gift certificates, except under specific statutory award or incentive programs an agency has separately authorized.
• Alcohol and entertainment, absent a specific, separately documented statutory exception.
• Travel-related expenses that belong on the separate GSA SmartPay travel card rather than the purchase card (airfare, lodging, per diem-eligible meals).
• Cellular phones, phone service, and other telecommunications purchases, which most agencies route through a separate acquisition process.
• Real property, construction, and firearms/ammunition, which fall outside the purchase card’s intended scope entirely.
• Information technology hardware and software above an agency’s IT-specific approval threshold, which frequently requires a separate agency CIO or IT-acquisition-office sign-off under the Federal IT Acquisition Reform Act (FITARA) framework, independent of whether the dollar amount is under the micro-purchase threshold.
• Split purchases used to circumvent any of the limits or approval steps above — not a category of item, but a method of purchase that is itself prohibited regardless of what is being bought.

Because agency lists vary, the operational rule for a cardholder in a research or lab setting is simple: check the current agency-specific restricted-purchase list and MCC-block list before assuming a purchase is allowed, particularly for anything IT-related, anything that could be read as personal benefit (conference meals, promotional items, memberships), or anything unusually large relative to routine lab consumables.

The GPC in a Federal Research or Laboratory Setting

For federal intramural research programs and government laboratories, the GPC is typically the default mechanism for routine, low-dollar lab purchasing — reagents, consumables, small parts, minor bench equipment, subscriptions, and similar recurring needs that fall under the micro-purchase threshold. It exists specifically so a principal investigator, lab manager, or designated cardholder can buy what a bench needs without generating a purchase requisition and waiting on a contracting officer for every routine item, while still leaving an auditable transaction and documentation trail behind each purchase.

That convenience comes with the same guardrails as any other federal purchase: purchases still have to be within the cardholder’s authorized scope, still need supporting documentation tied to the correct project or funding line, and are still subject to the prohibited-item and split-purchase rules above. Lab-specific complications worth flagging to an A/OPC in advance include controlled or hazardous materials (which may require separate licensing or shipping documentation regardless of dollar amount), select agents, and items requiring export-control review — none of which the card system itself screens for automatically.

GPC vs. an Institutional Procurement Card (P-Card)

It is easy to conflate the GPC with the purchasing card a university, hospital, or other grant-recipient institution issues to its own staff, but the two sit under different authorities:

• The GPC is issued by a federal agency, to a federal employee, under GSA SmartPay, and is governed directly by the FAR and OMB Circular A-123 Appendix B — it is a tool of direct federal purchasing.
• An institutional P-card (see CASRAI’s Procurement Card (P-Card) entry and the Procurement Card Program guide) is issued by a non-federal entity — a university, hospital, or research institution — to its own employees, under that institution’s own policy. When purchases on that institutional card are charged to a federal grant or cooperative agreement, they become subject to 2 CFR 200’s procurement standards (including the same micro-purchase threshold definition) rather than to the FAR directly; CASRAI covers that specific compliance layer in Procurement Card (P-Card) Compliance on Federal Awards.

A federal intramural researcher uses a GPC. A university researcher spending federal grant money through their institution’s own card program uses an institutional P-card operating under 2 CFR 200 — a related but legally separate arrangement.

Frequently Asked Questions

What is a government purchase card (GPC)?

It is a charge card issued by a federal agency to an individual federal employee, under the GSA SmartPay program, for making authorized low-dollar purchases directly from vendors without a full purchase-order process. It is governed by the FAR and OMB Circular A-123, Appendix B, plus the issuing agency’s own implementing policy.

What are the government purchase card limits?

Each cardholder has a single-purchase limit and a monthly (billing-cycle) limit, both set by the issuing agency. Single-purchase limits are generally set at or below the federal micro-purchase threshold ($15,000 as of the October 1, 2025 inflation adjustment), though some cardholders are authorized higher limits under agency-specific delegations for particular circumstances.

What are the government purchase card rules?

Purchases must be for an authorized government purpose within the cardholder’s delegated authority, priced reasonably, documented with a receipt or invoice tied to a funding source, reconciled by the cardholder, and certified by an approving official each billing cycle. Splitting a purchase to stay under a limit is prohibited, and cardholders must complete required training to keep the card.

What is on the government purchase card prohibited items list?

Commonly prohibited or tightly restricted categories include cash advances, personal purchases, gifts and gift cards, alcohol and entertainment, travel expenses (which belong on the separate travel card), telecommunications purchases, real property and construction, firearms, and IT purchases above an agency’s IT-approval threshold. The complete list is set by each agency’s own implementing regulation, so cardholders should confirm the current agency-specific list rather than assume a governmentwide default.

Is a government purchase card the same as an institutional P-card?

No. A GPC is issued by a federal agency to a federal employee under the FAR and OMB Circular A-123, Appendix B. An institutional P-card is issued by a university, hospital, or other non-federal entity to its own staff under that entity’s own policy, and becomes subject to 2 CFR 200’s procurement standards only when the purchase is charged to a federal award.
