California: Sales Tax Handbook
What is included in California's sales tax basis?
Many times, an otherwise-taxable transaction will include bundled fees like excise taxes, installation fees, or finance charges or be modified with coupons, installment payment plans, etc. One question that will often arise is whether or not a certain payment or fee is included in a transaction's taxable basis.
The taxable basis refers to the portion of an entire transaction that is subject to California's sales tax. This page answers common questions about which common fees are included in the sales tax basis in California, and which are excluded.

How are installment-based sales taxed?

How can I get reimbursed for sales taxes paid on items that are returned or repossessed?
If a taxable good for which sales tax has been collected is returned or reposessed by the merchant, the state may allow the amount of sales tax collected to be either deducted from the merchant's current sales tax balance or refunded to the merchant by the state. California's policies state that returns and repossessions are:
Deductible, if the purchaser receives a full refund of the sales price including tax, and the purchaser is not required to purchase other property at a price greater than the returned merchandise in order to obtain a refund or credit
Note: Repossessions are deductible if the entire amount paid by the purchaser is refunded, or if a credit for a worthless account is allowable
How can I get reimbursed for sales taxes paid on bad debts?
If a merchant offers goods to a consumer on credit and the payment for those goods becomes delinquent, the merchant may be eligible to be reimbursed any sales tax they paid to the state on the consumer's behalf when the transaction was made. The method of reimbursement varies state by state.
Tax paid on bad debts can generally be recovered by the merchant as a deduction.
