A small company hands out cards to its crew. One employee swipes a few thousand dollars past what anyone expected. Who pays? Many people assume the employee is on the hook for everything. Others assume the employee is never responsible. Federal law says something narrower than either guess, and it leaves some questions open.
What the federal rule covers
The main provision is 15 U.S.C. § 1645, titled "Business credit cards; limits on liability of employees." It applies when a business or organization gets cards from the same card issuer for ten or more of its employees. Picture a landscaping company with twelve crew leads, all carrying cards from one issuer. That fits the threshold. A shop with three cards does not.
Here is the core rule. Neither the business nor the card issuer may hold an employee liable for unauthorized use of a business card, except in accordance with, and subject to the limits of, § 1643. That companion section is the general consumer protection on unauthorized card use. So the employee's exposure is capped by that section and is not left open-ended. This article does not quote § 1643, because its text was not in the sources reviewed. Readers should check the statute itself for the actual limits.
The provision was added by Pub. L. 93-495 and took effect October 28, 1974. It is not a new idea. It has been part of federal credit law for decades.

How a business and issuer can divide liability by contract
The statute also lets the issuer and the business agree by contract on the business's own liability for unauthorized use of those employee cards. That agreement can operate without regard to § 1643. This contract route is tied to the same ten-card threshold.
Notice who is parties to that contract: the business and the issuer. The employee is not. So the written agreement matters a great deal. A reader who runs into a business card program should look at the actual paperwork instead of assuming the § 1643 limits settle every question about who pays.
One more technical point. The statute says the usual exemption under section 1603(1) does not apply to §§ 1642, 1643 and 1644 for these arrangements. In plain English, business-purpose credit is normally outside many consumer credit protections, and this provision pulls these cards back in for those sections. Congress treated them as a special category.
Unauthorized use versus overspending
Now the myth worth busting. Many people read this law as "employees can never be charged for what they overspend." The statute is framed around unauthorized use. The sources reviewed here do not define that phrase. They also do not say whether an employee who had permission to use the card, but went over a budget or broke an internal rule, counts as unauthorized.
That gap matters. Take two cases. In the first, a former employee keeps an old card and buys fuel for a personal trip. Nobody gave permission. In the second, a current employee is told to buy supplies up to $500 and spends $900 at the same store. Permission existed, but the amount broke the rule. The statute's protection is aimed at the first picture. Whether the second counts is not something these sources answer, so nobody should assume the federal protection automatically covers ordinary overspending.
A business that sees a problem charge could ask three questions:
- Did the employee have permission to make this charge?
- Does the business have a contract with the issuer on unauthorized use?
- Does the program meet the ten-card threshold?
Those are questions for the written agreement and for a qualified professional, not conclusions this article can reach.
Limits of this overview and related reading
Several pieces are missing. The text of § 1643 is not in the sources, so its specific limits are not described. The Consumer Financial Protection Bureau lists 12 CFR 1026.12, "Special credit card provisions," as part of Regulation Z, the Truth in Lending rule, but the excerpt available was mostly navigation. You can look at it on the CFPB's page for that section.
The sources also say nothing about state law, internal spending policies, how disputes among employers, employees and issuers get resolved, or what to do after an overcharge. They do not cover cards issued to fewer than ten employees, which fall outside the § 1645 contract provision. For the statute itself, see 15 U.S.C. § 1645 at Cornell's Legal Information Institute. For general background on how card accounts are managed, the CFPB publishes a credit card account management examination guide, though its content was not reviewed for this piece.
