Short answer
For most restaurant bills, the cleanest method is to calculate the tip on the pre-tax subtotal. That bases the tip on the food and service amount rather than the local sales tax.
Tipping after tax is not wrong. It is simply a little more generous and can be easier when the payment screen shows only the final total.
Subtotal vs after-tax total
| Receipt line | What it means | Tip use |
|---|---|---|
| Subtotal | Food and drink before tax | Common base for pre-tax tipping |
| Tax | Sales tax added by location | Not part of subtotal |
| Service charge | Business-added fee | Check before adding more |
| Total | Amount before optional added tip | Used for after-tax tipping |
Before-tax and after-tax comparison
Suppose a receipt has a $62 subtotal and $5.27 tax, so the after-tax total is $67.27.
| Tip % | Tip on subtotal | Tip after tax | Difference |
|---|---|---|---|
| 15% | $9.30 | $10.09 | $0.79 |
| 18% | $11.16 | $12.11 | $0.95 |
| 20% | $12.40 | $13.45 | $1.05 |
The difference is small on everyday bills but grows on large group meals.
Suggested tip screens can differ
Restaurant receipts and card screens may calculate suggested tips from the subtotal, after-tax total, total after fees, or original total before discounts. That is why a suggested 20% tip may not match your mental math.
If you want a service-type range first, use the Tipping Guide. If you want broader context, read How Much Should You Tip?.
Automatic gratuity and service charges
If the receipt says automatic gratuity, gratuity included, or service included, a tip may already be part of the bill. You can add more if you want to, but check first so you do not double tip.
Discounts can also affect the base. Some diners tip on the pre-discount subtotal when the server handled the full meal, but this is a personal etiquette choice.
Formula examples
Pre-tax tip = Subtotal x Tip percentage / 100 After-tax tip = After-tax total x Tip percentage / 100
For a $50 subtotal and 20% tip, the pre-tax tip is $10. If tax makes the total $54, a 20% after-tax tip is $10.80.
Group meals
For shared restaurant bills, decide the tip basis before splitting. Then use the restaurant bill-splitting guide or the Split Bill Calculator to divide tax and tip fairly.
Trust note
Pre-tax vs after-tax tipping is etiquette guidance, not a legal rule. Check the receipt for service charges, automatic gratuity, discounts, and how suggested tips are calculated.
