From Policy to Reality: The U.S. Cash Rounding Patchwork Has Begun

Source Overview

As of March 25, 2026, cash rounding legislation has been signed into law in Arizona (HB 2938, March 14), Indiana (SB 243, March 5; HB 1406, March 12), Tennessee (HB 1744, March 18), and Washington (HB 2334, March 23). Florida, Virginia, Oregon, Iowa, Hawaii, and Maryland have passed bills through both chambers and await governor action. Federal legislation (Common Cents Act, H.R. 3074) remains stalled in committee. The result: state-by-state implementation is now the default path forward. Economic pressure data underscores the urgency. The Richmond Federal Reserve found that penny elimination creates an estimated annual "rounding tax" of approximately $6 million (about 5 cents per household per year), rising to $56 million if both penny and nickel are eliminated. On the merchant side, NACS reports rounding down costs the convenience store industry approximately $1 million per day. The National Restaurant Association estimates consistent consumer-favorable rounding could cost the restaurant industry $13-14 million per month. The NRF documented up to 4 cents loss per transaction and flagged SNAP compliance risk. RILA surveys found 25% of major retailers had 1,000+ stores operating without pennies, with 67% rounding in the customer's favor and absorbing losses. Legal and litigation risk is escalating. UDAP (Unfair and Deceptive Acts and Practices) exposure exists in every state where rounding methodology is not legislatively defined. SNAP/EBT transactions present federal compliance risk if rounding is applied to government-benefit purchases. At least 10 states and localities have cash discrimination laws that could conflict with rounding practices. The first class action lawsuit related to rounding is widely anticipated as a market acceleration event. Global precedent offers important context. Canada successfully eliminated the penny in 2013 with clear federal rounding guidance established before phase-out. Australia phased out its one-cent and two-cent coins in 1992 with legislated symmetric rounding. New Zealand eliminated one-cent coins in 1990 and five-cent coins in 2006 with escalating rounding thresholds. In each case, the government established uniform rules before or concurrent with elimination. The U.S. is the first major economy to eliminate a denomination without pre-established national rounding standards. On the policy horizon, the Common Cents Act (H.R. 1270/3074) remains stalled. Treasury has issued guidance recommending symmetric rounding but has not mandated compliance. The Federal Reserve continues to manage coin logistics but has not addressed rounding standardization. Meanwhile, nickel production costs (13.78 cents per coin) suggest the nickel may be next, which would require rounding to the nearest dime and compound the current compliance challenge exponentially.

Key Takeaways

• Four states (Arizona, Indiana, Tennessee, Washington) have signed rounding laws, with six more awaiting governor action
• Washington has adopted asymmetrical rounding, diverging from the symmetrical model used by Arizona and recommended by Treasury, creating the first real methodology split
• No deterministic rounding logic exists in the current POS market. Most systems lack jurisdiction-aware rounding engines
• Audit trail consistency is absent. No standardized method exists for recording, verifying, or reconciling rounding adjustments across transactions
• Multi-state retailers face immediate complexity: different rules in different states with no unified compliance framework
• Tax, audit, and compliance risk increases with every new state that enacts its own approach
• POS systems are not designed for jurisdiction-aware rounding. Most handle rounding as a display layer, not a policy layer
• "Close enough" accounting is common in practice but not defensible under the enforcement provisions being written into state law
• Richmond Fed research quantifies the consumer rounding cost at $6M annually, rising to $56M if nickel is also eliminated
• RILA data: 25% of major retailers had 1,000+ stores without pennies; 67% absorbing losses by rounding in customer favor
• NACS estimates rounding down costs convenience stores $1M per day; NRA projects $13-14M/month for restaurants
• UDAP exposure in states without defined rounding methodology creates litigation risk for every retailer
• SNAP/EBT compliance risk if rounding is applied to government-benefit cash transactions
• At least 10 states/localities have cash discrimination laws potentially conflicting with rounding
• Canada, Australia, and New Zealand all established uniform national rules before or during coin elimination. The U.S. has not
• Nickel production costs (13.78 cents) suggest the nickel may be eliminated next, compounding compliance requirements
