California Sales Tax Calculator
Calculate California sales tax by county with exact 2024 district rates. Supports multiple items, exemptions, and generates printable tax receipts.
About
California imposes a statewide base sales tax rate of 7.25%, composed of a 6.00% state levy plus a mandatory 1.25% local allocation. Individual counties and special taxing districts layer additional rates on top, pushing combined rates from 7.25% to as high as 10.75% in parts of Los Angeles County. Miscalculating by even 0.25% on a $50,000 commercial purchase creates a $125 discrepancy that triggers CDTFA audit flags. This calculator applies the correct combined rate for all 58 California counties, handles multi-item subtotals, and produces an itemized receipt suitable for bookkeeping. Note: rates reflect standard district levies and may not capture hyper-local transportation or housing authority surcharges approved after July 2024.
Formulas
The California sales tax applied to any purchase is computed as the product of the pre-tax subtotal and the applicable combined rate for the transaction's county. The combined rate is the sum of the statewide base and the local district surcharge.
where T = tax amount in $, S = pre-tax subtotal in $, and rcombined = combined sales tax rate in %.
where rstate = 7.25% (fixed statewide base comprising 6.00% state + 1.25% mandatory local), and rdistrict = additional voter-approved district tax (0.00% to 3.50% depending on jurisdiction).
For multi-item transactions, the subtotal S is computed as:
where qi = quantity and pi = unit price of the i-th item. All monetary results are rounded to the nearest cent using banker's rounding.
