Do any USA states require accepting US cash for payment of goods or services?

Question

According to the United States Federal Reserve:

There is no federal statute mandating that a private business, a person, or an organization must accept currency or coins as payment for goods or services. Private businesses are free to develop their own policies on whether to accept cash unless there is a state law that says otherwise.

Are there any states, districts, regions, or territories within the USA that mandate that a private business, a person, or an organization must accept US currency or coins as payment for goods or services?

Answer 1

Not at the level of the state, but businesses subject to King County (WA) jurisdiction will, effective Jan. 1 2025, have to accept cash (within limits: not larger than $20 bill, not more that $200) for in-person transactions. Ad hoc exemptions are allowed in case of significant theft history, business operated at home, or with only one on-site employee.

Answer 2

Yes. In massachusetts, the General Law, chapter 255D, section 10A outlaws discrimination against cash buyers by retail (as opposed to wholesale) businesses. The section reads, in full:

Section 10A. No retail establishment offering goods and services for sale shall discriminate against a cash buyer by requiring the use of credit by a buyer in order to purchase such goods and services. All such retail establishments must accept legal tender when offered as payment by the buyer.
