California combined rates

Many metros land between 8.25% and 10.75%. LA, San Francisco, and San Diego shoppers should use the rate printed on the receipt or CDTFA lookup for the delivery address.

Worked example: $162.38 at 9.5% → Original = $148.29, tax = $14.09.

Worked reverse tax example

You paid $108.25 including 7.25% sales tax and need the merchandise amount for bookkeeping.

Convert rate: 7.25% ÷ 100 = 0.0725
Add 1: 1 + 0.0725 = 1.0725
Divide: $108.25 ÷ 1.0725 = $100.93
Tax portion: $108.25 − $100.93 = $7.32

Pre-tax: $100.93 | Tax: $7.32 | Total: $108.25

Compliance reminder

Reverse math is for splitting receipts and estimates—it does not replace filing obligations, nexus analysis, or professional tax advice. Confirm rates with your state revenue department or marketplace reports before remitting.
