Recent tax rate changes in California

California adjusted the tax rate on other tobacco products (OTP), including vapor products, from 61.74% to 56.32% of the wholesale cost. This change is required to bring the OTP tax rate in line with the effective tax rate on cigarettes. Since April 2017, California's cigarette tax has been a fixed $2.87 per pack of 20. But as average cigarette prices have increased, the effective tax rate has declined, helping maintain the prices.

FAQs

How do you calculate California sales tax?

To calculate California sales tax, you can use the formula:

Sales tax = (base rate + local rate) * purchase price.

For example—if the base rate is 6%, the local rate is 1.25%, and the purchase price is $100, the sales tax would be $7.25.

What are the penalties for not paying California sales tax?

Businesses that incorrectly file or pay California sales tax can attract penalties of up to 10% of their unpaid tax amount.

What’s the difference between destination-based and origin-based sales tax states?

The critical difference lies in how the sales tax rate is determined for transactions.

• Destination-based sales tax is based on where the purchased product or service will be consumed or delivered.
• Origin-based sales tax is based on where the seller is located. This is a more convenient form of tax collection. However, there are very few states that choose origin-based sales tax.

Is the California sales tax destination-based or origin-based?

California has a modified origin-based sales tax system.

State, county, and city taxes are based on where the sale originates from. However, district taxes are based on where the buyer is located.

Is California a streamlined sales tax state?

California is not a Streamlined Sales Tax State.

The Streamlined Sales Tax Project (SSTP) aims to simplify sales tax collection across states that adopt its Streamlined Sales and Use Tax Agreement (SSUTA), and California still needs to join the SSTP or implement the SSUTA.

Sales tax nexus and registration

The sales tax nexus is a crucial link between a business and a state, mandating the business to collect and pay sales tax on all the transactions that take place within that state.

A company may reach nexus in California and will require a seller’s permit by

• Having representatives, agents, or contractors working in California to make sales, take orders, assemble or install products, train customers, make deliveries, or develop the market.
• Receiving rental income from leasing tangible property located in California like machinery, equipment, or furniture.
• Owning or leasing real estate or other property in California such as equipment, furniture, or computer servers.
• Having total sales of tangible personal property delivered in California exceeding $500,000 during the previous or current calendar year.

Once you have established a sales tax nexus in California, you are required to register for a sales tax permit and collect and remit sales tax on all of your sales in the state.

Collecting sales tax in California

Let’s look at the steps to collect sales tax in California now.

How to collect sales tax in California if you are not based in California (Out-of-State)

Even if you do not have a physical presence in the state, you must register with CDTFA if you’re considered " engaged in business" in California. You can voluntarily register to collect and pay use tax for your California customers.

There are 5 common ways to be considered as “engaged in business”:

Should you collect sales tax on shipping charges in California?

The California Department of Tax and Fee Administration (CDTFA) provides specific guidelines on applying sales tax to delivery-related charges.

For delivery charges to be non-taxable, the shipment must go directly to the purchaser via common carrier, contract carrier, or US Mail. The invoice should clearly list the delivery, shipping, freight, or postage as a separate charge that does not exceed the actual delivery cost to the customer. However, if records are not maintained showing the actual delivery cost, the charge becomes taxable.

Delivery charges are partially taxable if the conditions above are met, except if the charge to the customer is higher than the actual shipping cost. They are also partially taxable if there is a combined "shipping and handling" or "postage and handling" charge.

Delivery charges are fully taxable if records of actual delivery costs are not kept if the seller uses their own vehicles for delivery if there are separate fuel surcharges or "handling" fees if the charge is built into the item's price, if it represents shipping costs to the seller's place of business, or if the sales agreement specifies delivery is included in the overall price.

The auditor will then review the business's records and tax returns to determine if any sales tax was not paid. If the auditor finds any discrepancies, they will issue a report with their findings.

The business then has the opportunity to appeal the findings to the CDTFA. If the appeal is denied, the business can then appeal to the California Superior Court.

• MAP allows eligible businesses to conduct a self-audit under CDTFA guidance, with benefits like reduced interest rates.

• The auditor verifies the work, explains the results, and completes the audit.
