Rounding, Smart Tax, Coin Elimination

Hello, I am a restaurant operator running multiple sit-down restaurants on Toast. Very hands-on with pricing, tax setup, and day-to-day front-of-house operations. Been with Toast for around 4 years and seen all the crazy speed of improvements it made, and probably they are already tracking this problem, but wanted this topic to be refreshed with some of my insights on the current smart tax system and what to watch out for when they do make a system that fixes some of the problems we are all facing.

The idea behind Smart Tax makes sense — fewer coins should mean faster checkout, fewer mistakes, and easier cash handling. But in real-world use, there are too many major cons that can hurt the business.

Here’s what we’re seeing in practice:

Smart Tax requires whole-number, tax-inclusive pricing
Operators are forced to back into pricing using tax-included amounts rather than setting clean menu prices the way most restaurants do.
This creates awkward and uncompetitive menu pricing
Customers naturally compare prices pre-tax. Once prices are reverse-calculated from tax-inclusive amounts, operators are left with two bad choices:
Either clearly label menus as post-tax (which most guests don’t read), or display pre-tax prices that land on awkward cent amounts like $15.57. Neither option works well.
Most guests compare prices pre-tax, not after tax
Whether it’s printed menus, Google, or third-party platforms, guests anchor on pre-tax pricing, even if tax is technically included.
Auto-Gratuity reintroduces coins anyway
Percent-based gratuity almost always creates cents, so coins show up on the final check even though Smart Tax was meant to eliminate them. This pretty much makes the system unusable if there is a large party we want to autograt.

Receipts don’t clearly show the tax amount when using Smart Tax
This creates confusion for guests who want to see how much tax they paid and makes it harder for operators to explain charges, answer questions, or reconcile transactions. You would be surprised how many guests write reviews saying we are overpriced because the receipt shows menu prices post-tax with 0 on the tax line, when separating the items would eliminate the misunderstanding.

The result is that operators bear the pricing and perception downsides of Smart Tax while still dealing with coins at checkout.

Why this matters day to day

Coins slow down checkout and table turns
Even a few extra seconds per transaction adds up during peak hours.
Counting change increases mistakes
More coins mean more opportunities for miscounts, especially with newer staff or high volume. I am pretty sure everyone knows shorts and overages on cash drawers are essential to track because they can be used to determine whether an employee is making too many mistakes or making mistakes on purpose for financial gain
US is already talking about getting rid of certain coins
It seems they are trying to get rid of pennies and nickels. Might as well have this feature sooner than later.

Some ideas that could really help

Separate guest-facing menu pricing from tax logic (Probably the most needed since it fixes the receipt problem)
Let operators keep clean, pre-tax menu prices while Smart Tax handles rounding internally.
Allow rounding at the final total (after tax + auto-grat)
This would actually eliminate coins in real-world scenarios.
Make Smart Tax and Auto-Grat coordinate on rounding (can do this if the rounding at total cannot happen)
Without this, the core benefit of Smart Tax gets canceled out.
Offer a true end-to-end “coinless mode”
One setting that ensures final totals don’t require coins, regardless of tax or gratuity.

This would save operators time and money, reduce mistakes, and better reflect the reality that the U.S. is gradually moving away from coins. It also feels like a win for Toast — higher Smart Tax adoption, fewer support issues, and a smoother day-to-day experience for operators — maybe a selling point, since multiple restaurants really struggle with training costs and integrity-check systems.

Knowing Smart Tax hasn't been touched since launch, I kind of just jumped on Smart Tax when, honestly, we just need a better system.
