How to use it
- Enter the purchase amount in dollars.
- Enter the total sales‑tax rate shown on your receipt.
- Click Calculate to view the tax breakdown.
What it does – You enter the purchase amount and the total sales‑tax rate you were charged. The tool instantly splits the tax into the mandatory 6.00 % state portion, the 1.25 % county/city Bradley‑Burns rate, and any extra district or city surcharge above the 7.25 % baseline. Why it matters – Knowing each component helps you verify that a retailer applied the correct tax, plan budgets, and compare offers across jurisdictions. How to read the results – Total Sales Tax shows the dollar amount added to your purchase. Total Amount with Tax is what you’ll actually pay. State Portion and Mandatory County/Local are fixed by law; District/City Taxes is the remainder, reflecting local voter‑approved rates. You can copy the breakdown into spreadsheets, use it for expense reports, or confirm refunds on returns, and it works for any purchase size.

- Round the tax amount to the nearest cent for accounting consistency.
- Double‑check that the rate you entered includes any special district surcharge.
