Since the United States Treasury minted its final penny Nov. 12, 2025, some businesses in Wisconsin and across the country have begun rounding change in cash transactions to five-cent intervals, with different businesses utilizing different methods of rounding — some rounding up, some rounding down, and some a mix of both.
The Wisconsin Department of Agriculture, Trade and Consumer Protection and Wisconsin Department of Revenue have issued guidance to businesses that are considering implementing a rounding practice to simplify and standardize rounding practices in Wisconsin to provide greater predictability and protection for Wisconsin consumers.
Given pennies are no longer being minted, they may not always be available at cash registers to make exact change during cash transactions. This decision by the federal government has left many businesses in a difficult situation when processing cash transactions that would normally require penny change back to the consumer.
Cash rounding is applicable only to cash transactions where change is required after the total amount due (price plus tax) has been calculated and cannot be provided. While businesses can choose their rounding methodology, DATCP’s guidance to businesses suggests rounding down to the nearest five cents to ensure the customer is not negatively impacted by rounding practices.
Regardless of the methodology a business chooses to adopt for cash rounding, DATCP encourages businesses to post a clear and informative flyer conspicuously at entrances and any point of sale communicating any rounding policy.
DATCP suggests that businesses round down to minimize consumer harm and ensure fairness and consistency where $0.01, $0.02, $0.03, or $0.04 round down to zero, while $0.06, $0.07, $0.08, or $0.09 round down to $0.05.
Consumers should refer to a business’s posted methodology for cash rounding in advance of making a cash purchase. Alternatively, consumers may choose to use a non-cash payment method, such as a debit or credit card, to avoid rounding.
DATCP will use discretion enforcing state regulations related to the Unfair Sales Act; Price Accuracy; and Untrue, False, or Misleading Representations complaints to ensure that all consumers are treated fairly.
DOR has provided additional guidance to retailers about the calculation of Wisconsin sales and use taxes due on cash transactions impacted by penny shortages. Cash rounding does not impact sales tax collection and remittance amounts to the State. Learn more from DOR at https://www.revenue.wi.gov/Pages/TaxPro/2026/SalesTaxPennyShortage.aspx.
