The Penny Is Going Away. Checkout Still Has to Make Sense.

The penny may be small, but the operational mess around it is not.

Now that the U.S. Mint has ended production of circulating pennies, retailers have a practical question to answer: what happens when a cash transaction does not land neatly on a nickel?

That question sounds simple until it reaches the register.

An associate rings up a basket. Sales tax is calculated. The customer pays in cash. The drawer does not have pennies. The associate has to explain why the total on the screen, the amount collected, and the change given may not all look exactly the same. Then the customer looks at the receipt.

That moment is where cash rounding stops being a coin story and becomes a checkout workflow story.

What changed with the penny?

On November 12, 2025, the U.S. Mint hosted the ceremonial strike for the final circulating one-cent coin, ending the penny's 232-year production run as a circulating coin. The Mint also stated that pennies remain legal tender and that retailers can continue pricing goods and services in one-cent increments.

That last part matters. Penny production ending does not mean every price suddenly needs to end in zero or five. A retailer can still sell an item for $9.99. Sales tax can still be calculated to the cent. Card payments can still settle to the exact cent.

The friction appears when a cash transaction needs penny change and the store cannot provide it.

The U.S. Treasury has said merchants will need to round transactions up or down to the nearest five cents as pennies fall out of circulation. Treasury also recommends that non-cash payments, including checks, credit cards, and debit cards, continue to be priced and processed to the exact cent.

In other words, the issue is not really pricing. It is payment handling.

Why the adjustment belongs at the end of the transaction

For retailers, the cleanest way to think about penny handling is this: calculate the sale first, handle the cash adjustment second.

That distinction protects the integrity of the transaction. Product prices do not need to change just because the customer is paying with cash. Sales tax should still be calculated on the taxable sales price under the applicable state rules. Discounts, fees, returns, exchanges, and other transaction details still need to be recorded accurately.

Then, if exact penny change is not available, the final cash amount can be handled according to the retailer's policy and applicable law.

Several public sources point in this direction. Streamlined Sales Tax guidance says that sales tax calculations remain unchanged regardless of payment type. Washington's Department of Revenue has issued similar interim guidance, saying that whichever rounding method is used, sales tax remains due on the sales price before the retailer applies rounding due to the lack of pennies.

That is an important operational idea. The POS should preserve the real transaction and separately handle any cash rounding or adjustment.

There is a customer-experience choice hiding inside the policy

Some state guidance focuses on rounding the final cash amount to the nearest nickel. In that model, one transaction may round down while another rounds up. That may be allowed under a state's cash-rounding framework, but it is not the only practical way to keep checkout moving when pennies are unavailable.

Retailers should be careful about what is actually being adjusted. The cleanest operational model is not to change the item price or recalculate tax. It is to calculate the sale and tax first, then apply any penny difference afterward as a separate, non-taxable cash adjustment funded by the merchant.

In that model, if the total is $32.03, the retailer can collect $32.00 and absorb the three cents as a cash adjustment. The customer is not being charged more than the calculated sale total. The tax calculation stays tied to the original sale. The receipt can show what happened. And the associate does not have to defend two cents at the register.

That distinction matters. Even stricter state approaches generally care that tax is calculated before any cash adjustment. Arizona guidance says rounding must be applied only after the full transaction, including taxes and fees, has been calculated. Florida guidance says sales tax remains due on the actual sales price before rounding. Washington guidance also says whichever rounding method is used, sales tax remains due on the pre-rounding sales price.

The practical takeaway is simple: do not bury penny handling inside item pricing or tax logic. Keep it visible as a cash-handling adjustment after the transaction is calculated. When the merchant absorbs the penny difference, the customer experience is easier to explain and the tax record remains clean.

The associate has to explain it

It is easy to design a rounding policy in a conference room. It is harder to make it work at lane three on a busy Saturday.

The customer may be short on time. The associate may be new. The line may already be building. A two-cent question can still slow down checkout if the store has not made the policy simple and visible.

So the real question for retailers is not just, “What rounding rule should we use?” It is also, “Can our associates explain the rule quickly, consistently, and without turning checkout into a debate?”

USPS provides one public example of how a formal rounding policy can work. Its penny-rounding policy says change due to the customer ending in 1, 2, 6, or 7 cents is rounded down, while amounts ending in 3, 4, 8, or 9 cents are rounded up. USPS also notes that pennies remain legal tender and are still accepted as payment.

That kind of rule may make sense for a large public institution that needs one standardized process across a massive network. For a retailer, though, it can feel like a lot to ask of the associate and the customer. Explaining why one shopper saves two cents while the next shopper pays two cents more is technically manageable, but it is not exactly a recipe for a warmer checkout moment.

Retailers do not need to make penny handling feel more complicated than it has to be. Their rules may depend on state law, tax guidance, store policy, and legal review. But the lesson is useful: whatever the policy is, customers need a simple explanation before they feel surprised.

Where penny handling can get messy

Penny handling sounds like a single setting. In real retail operations, it touches more than that.

• Receipts: The receipt should show the original total, the cash adjustment, and the final cash amount clearly enough that customers and managers can understand it later.
• Returns and exchanges: A return tied to a rounded or adjusted cash sale may need careful handling so the customer, drawer, and accounting records stay aligned.
• Split payments: If part of the transaction is paid by card and part by cash, the store needs a clear rule for whether an adjustment applies and to which portion.
• Tax reporting: A cash adjustment should not accidentally change taxable sales or tax collected in the system of record.
• Drawer reconciliation: Managers need to understand whether penny differences are tracked, reported, or treated as normal operating variance.
• Multi-state operations: Retailers operating across states may face different guidance or legal expectations.

None of these issues is dramatic on its own. But retail is full of tiny exceptions that become expensive when they happen thousands of times across stores.

What retailers should review before penny adjustments become routine

Retailers should treat penny handling like a small operational change with a wide reach.

Start with policy. Decide when an adjustment applies, which payment types are affected, how split tenders are handled, and how associates should explain the policy to customers. Make sure the policy is reviewed against state and local requirements.

Then review the POS workflow. The system should make the adjustment visible without forcing associates to improvise. Ideally, it should distinguish between the calculated transaction total and the final cash amount.

Next, look at receipts and reporting. A customer should be able to see what happened. A store manager should be able to reconcile the drawer. Finance should be able to trust that tax and sales reporting still reflect the original transaction properly.

Finally, train the front line. Associates do not need a legal memo. They need a short, plain explanation: pennies are still accepted, but when exact penny change is not available, the store may adjust the cash amount according to policy. Card payments still process to the exact cent.

The bigger lesson for checkout

Penny handling is a good reminder that checkout is not just a payment endpoint.

It is where pricing, tax, tender, inventory, returns, receipts, store policy, associate training, and customer trust all meet. When something changes in one part of that system, the register is where the change becomes visible.

That is why retailers should resist treating cash rounding as a minor back-office setting. It is small, yes. But it is also exactly the kind of edge case that reveals whether store systems are cleanly connected and whether associates have the tools they need to keep the line moving.

The penny may be leaving production, but the lesson is bigger than coins. Retail checkout keeps getting more complicated in small, practical ways. The retailers that handle those details well will make the experience feel simple to customers, even when the operation behind it is anything but.
