Tips and tax

Why is the tip calculated on tax?

A tip calculation can be difficult to check when the screen only shows a final total. This hub explains what to compare on the receipt and links to the archive’s documented tip-on-tax reports.

What a tip-on-tax report means

These reports describe a suggested tip that appears to use a total including sales tax. The wording matters: a screenshot may show the result, while a receipt or source explanation may be needed to establish the calculation.

Check the math before drawing a conclusion

Compare the pre-tax subtotal, tax, suggested tip, and final total. A cropped screen may not show enough information to reproduce the calculation, so we keep uncertain reports labeled and link to the original source.
