How-To Guides: California SaaS VAT

Step: 1 Threshold

You’ll need to collect sales tax in California if you have nexus in the state. Sellers can be tied to a state when it comes to nexus in two ways: physical or economic.

  • Physical nexus means having enough tangible presence or activity in a state to merit paying sales tax there.
  • Economic nexus means passing a state’s economic threshold for total revenue or the number of transactions in that state: USD $500,000 in total sales of tangible personal property for delivery into California in the current or prior calendar year (economic nexus rule).

While pure SaaS is generally treated as a non-taxable service, registration becomes mandatory if the SaaS model includes taxable components (e.g., canned software downloads, hardware, or bundled taxable products).

Step: 2 Business Registration

Register as a seller with the California Department of Tax and Fee Administration (CDTFA) through the online registration system. Foreign and out-of-state sellers must obtain a seller’s permit if they meet economic nexus or engage in taxable sales.

Step: 3 TIN/VAT Number

A California Seller’s Permit Number is issued by the CDTFA and functions as the sales tax identification number.

Step: 1 Standard Rate

California statewide base rate 7.25%, with district taxes increasing the combined rate up to ~10.75% depending on the customer location. SaaS is generally not taxable if no transfer of tangible personal property occurs.

Step: 2 Formula

To calculate your tax amount, use the following formula:

 

Tax Amount= Net Price × Rate%

Step: 3 Reverse Charge (B2B)

The U.S. does not operate a VAT-style reverse charge system. If SaaS is classified as a non-taxable service, no tax applies regardless of B2B or B2C. If taxable elements exist, the seller remains responsible for charging and remitting sales tax.

Step: 1 Selling B2C

Pure cloud-based SaaS with no download or transfer of tangible software is generally not subject to California sales tax. If the SaaS includes taxable digital goods or prewritten software delivered electronically in a taxable structure, tax may apply based on sourcing rules tied to the customer location.

Step: 2 Selling B2B

No reverse charge applies. Treatment mirrors B2C. If the transaction qualifies as a non-taxable service, no tax is charged. If bundled with taxable components, the seller must collect sales tax unless a valid resale or exemption certificate is obtained.

Step: 3 Invoice Requirements

Invoices should contain:

  • Seller legal name and address;
  • Seller’s Permit Number;
  • Invoice date;
  • Sequential invoice number;
  • Description of service/product;
  • Sales price;
  • Applicable tax rate;
  • Tax amount (if taxable);
  • Customer name and address;
  • Place of sale/location code;
  • Exemption certificate reference (if applicable).

Step: 1 Filing Interval

Assigned by CDTFA based on volume:

  • Monthly
  • Quarterly
  • Annual.

Step: 2 Filing Deadline

Returns are generally due on the last day of the month following the reporting period.

Step: 3 Submission

Filed electronically via the CDTFA Online Services Portal. Payments accepted via ACH debit, credit card, or electronic funds transfer.

Step: 4 Record Keeping

Minimum 4 years retention of sales records, exemption certificates, invoices, and accounting books.
