31 U.S.C. 5103: Legal Tender and Cash Refusal Rules

31 U.S.C. § 5103 makes U.S. coins and currency legal tender for debts, public charges, taxes, and dues. It does not create a general federal command that every private business accept cash for goods or services. The Federal Reserve explicitly distinguishes those propositions. [1][2]

What legal tender establishes

The statute identifies U.S. coins and currency, including Federal Reserve notes, as legal tender. The Federal Reserve describes this as a valid and legal offer of payment for debts when tendered to a creditor. The short provision does not prescribe every merchant’s checkout method, every contract’s payment terms, or every agency’s collection procedure. [1][2]

A sign announcing a card-only policy before a purchase raises a different question from a creditor refusing payment on an existing obligation. Determine whether there is already a debt, how the obligation arose, and which payment conditions apply before treating the phrase “legal tender” as a complete answer.

Why a cashless shop may be allowed

The Federal Reserve says no federal statute generally requires a private business, person, or organization to accept currency or coins for goods and services. Businesses may establish cash policies unless an applicable state law says otherwise. State or local cash-acceptance rules therefore need their own analysis. [2]

For example, a customer who sees a card-only notice before ordering should not assume § 5103 alone forces the shop to complete the transaction for cash. Conversely, the absence of a federal requirement does not establish that the same policy complies with a particular city’s cash-acceptance ordinance.

What to check in a payment dispute

  • Identify whether the transaction is a proposed purchase or an existing obligation.
  • Save the contract, bill, advertised payment policy, and any refusal.
  • Check the law governing that particular seller, service, or public payment.
  • Ask for the accepted payment methods and any available alternative in writing.

Do not assume a refused cash offer automatically erases a debt, prevents late charges, or ends a court case. Those consequences depend on rules beyond this statute. When a deadline matters, preserve proof of timely efforts to pay while identifying a valid payment route.

Authenticity is a separate issue

Legal-tender status concerns valid U.S. money. A dispute about whether a bill is counterfeit raises different criminal and factual questions from whether a store accepts cash at all. Likewise, a merchant’s concern about large bills is not answered merely by quoting the denomination printed on the note.

Use § 5103 for the proposition it actually establishes, then examine the applicable transaction and payment rules. That produces a more useful answer than assuming either that all cash refusals are unlawful or that every refusal is permitted.
