Some states are setting guidelines for rounding for cash purchases when there are no pennies. This comes after President Donald Trump announced the end of penny production, citing it as wasteful. This decision led to a shortage of pennies in stores and led to shortages of pennie. The Treasury Department plans to continue circulating the roughly 114 billion pennies that exist for as long as possible. One solution is rounding to the nearest nickel, using a practice called symmetrical rounding. Oregon House Bill 4178, which uses this solution, passed the state Senate on a 26-2 vote last week. In Indiana, a bill signed into law by Republican Gov. Mike Braun instructs businesses to round cash purchases for all transactions that do not end in a zero or five, and a second bill makes rounding optional. However, some state agencies have published guidelines to advise that rounding should occur after tax and that businesses must ensure that the full taxed amount still goes to the state.
