Transaction Rounding Overview

In light of the discontinuation of penny production by the U.S. Treasury and the resulting nationwide shortage, we have updated OnTrac to include a function to round all cash payments to the nearest nickel. This is based on a proposed bill called the Common Cents Act.

What is the bill

  • The legislation is called the Common Cents Act
  • Its primary goals:
    1. Direct the United States Department of the Treasury to stop minting the penny (one-cent coin) for general circulation. 
    2. Require that cash transactions be rounded up or down to the nearest five cents (i.e., the nearest nickel) — effectively replacing pennies with a nickel-based rounding system. 
  • The rationale: producing pennies has become economically wasteful — the cost of minting a penny significantly exceeds its face value. 
  • The bill also preserves status of existing pennies: any penny minted before enactment remains legal tender. 

Key details of how rounding works (and what’s proposed)

  • The rounding applies only to cash payments — electronic payments (credit cards, digital wallets, etc.) are not affected. 
  • The proposed standard rounding method is “symmetric” rounding:
    • If the total ends in 1 or 2 cents → round down to the previous nickel (e.g. $4.02 → $4.00)
    • If it ends in 3 or 4 cents → round up to next nickel ($4.03 or $4.04 → $4.05)
    • If it ends in 6 or 7 cents → round down to 5 cents ($4.06 → $4.05)
    • If it ends in 8 or 9 cents → round up to the next nickel/dime (e.g. $4.08 → $4.10) 
  • Transactions ending in 0 or 5 cents remain unchanged. 
  • According to economic-analysis (e.g. from the Federal Reserve Bank of Richmond), this rounding will likely have a negligible impact on inflation overall; the so-called “rounding tax” — extra cost to consumers due to rounding up — is estimated to be very small. 

Where to read the full language

What’s not settled — yet

  • The bill has been introduced and reported in the House (as of September 2025) — but as of now it is not law
  • Because no federal guidance existed until now, some retailers began unilaterally rounding — leading to confusion, operational headaches, and even potential legal risk.
