How California sales tax is worked out
California: 7.25% state tax plus the district tax of the buyer's registration address (type the combined district rate) on the price, the document processing charge and other charges. A trade-in does NOT reduce California sales tax, and an optional warranty is not taxed. The document processing charge is capped at $70 ($85 for a DMV Private Industry Partner) and must be disclosed as not a government fee. The Buyer's Order prints the 3-day right to cancel statement (used vehicles $50,000 or less) and, on an as-is sale, the as-is statement. Title fee starts at $28. The 3-day statement prints only on a used vehicle of $50,000 or less. The full disclosure the law requires (400-mile limit, restocking fee) is not printed: give it to the buyer separately.
Required wording beside the dealer fee
California requires this wording where the dealer fee appears. The Buyer's Order prints it.
THIS CHARGE IS NOT A GOVERNMENTAL FEE.
The as-is notice
California sets the wording for an as-is sale. DMS Apex prints it on the Buyer's Order when the sale is as is.
THIS VEHICLE IS SOLD "AS IS" OR "WITH ALL FAULTS". THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE VEHICLE IS WITH THE BUYER. SHOULD THE VEHICLE PROVE DEFECTIVE, THE BUYER, AND NOT THE MANUFACTURER, DISTRIBUTOR OR RETAILER, ASSUMES THE ENTIRE COST OF ALL NECESSARY SERVICING OR REPAIR.
Other required notices
California requires the following wording on the Buyer's Order. DMS Apex prints it.
- CALIFORNIA DOES NOT HAVE A COOLING-OFF PERIOD FOR NEW VEHICLES. HOWEVER, IF YOU PURCHASED OR LEASED A USED VEHICLE FOR $50,000 OR LESS, YOU HAVE 3 DAYS TO CANCEL THIS CONTRACT FOR ANY REASON. ADDITIONAL RESTRICTIONS MAY APPLY, INCLUDING A RESTOCKING FEE. You have up to 3 days to return the vehicle to the dealer and cancel this contract and obtain a refund. Please review the disclosure, which the dealer is required by law to provide, for the details about this right and how to exercise it.
