Who enforces counterfeiting laws for U.S. currency?

• A. Internal Revenue Service
• B. U.S. Secret Service
• C. U.S. Mint
• D. Department of the Treasury

Answer: (A)

The agency that enforces counterfeiting laws is the U.S. Secret Service. Its mandate includes investigating and preventing counterfeit currency, tracing the sources of fake notes, and supporting prosecutions to protect the integrity of the financial system. The Internal Revenue Service handles tax collection and enforcement, not counterfeit investigations. The U.S. Mint is responsible for producing currency and coins but does not enforce counterfeiting laws. The Department of the Treasury oversees broader financial policy and the agencies that handle currency, but actual enforcement against counterfeiters is carried out by the Secret Service (with collaboration from other partners).
