Yes, a California food truck charges sales tax, but only on part of the menu. Food truck sales tax in California falls on hot food, sodas, anything eaten at tables the truck sets out, and everything sold inside a ticketed event. Cold food and coffee or tea sold to go are generally tax-free.

The rate is California's statewide 7.25% plus local taxes where you park, and a truck selling mostly hot food can owe tax on its cold to-go items unless it tracks them separately.

What does a food truck charge sales tax on in California?

A California food truck charges sales tax on four kinds of sales: hot prepared food, sodas and other carbonated drinks, food eaten at tables or counters the truck provides, and everything sold inside a place that charges admission. Those are the rules the California Department of Tax and Fee Administration (CDTFA), the state agency that collects sales tax, applies to anyone who sells food or drinks from a truck, stand or wheeled cart.

A hot prepared food product is one that was cooked or heated for sale and is sold warmer than the air around it, and food meant to be sold hot stays a hot sale even after it cools in the bag, under Regulation 1603. Grilling a sandwich or holding food under heat lamps counts as preparing it hot.

Sodas and sparkling water are always taxable, because carbonated beverages are not "food products" under section 6359(b)(3) and Regulation 1602. Still bottled water, juice, iced tea and milk drinks sold to go are not taxable because they are food products, unless the truck comes under the 80/80 rule, a test for sellers whose sales are mostly hot food, and doesn't track these sales separately.

Food eaten at tables, chairs or counters the truck provides is taxable, under Regulation 1603(f) and Revenue and Taxation Code section 6359(d)(2). A truck that sets out folding tables turns the cold sandwich eaten at one of them into a taxable sale.

Is a combo meal taxable on a California food truck?

When one price covers a hot item and a cold side, tax applies to the whole price, even if the receipt itemizes the parts, under Regulation 1603(e)(1) and Revenue and Taxation Code section 6359(e). A single price shown on a menu or wall sign counts as an established single price. If a soda rides along in an otherwise cold combination, the portion of the price that represents the soda is taxable, per CDTFA's mobile food vendor web page.

Which food truck sales are not taxable in California?

Cold food products sold to go are generally not taxable, and neither are hot coffee, hot tea, or hot bakery goods like donuts and muffins when each sells at its own separate price. Publication 287, CDTFA's printed guide for mobile food vendors, lists cold sandwiches, milkshakes, smoothies, ice cream and cold salads among the cold food products that generally carry no tax.

The hot-drink and bakery carve-out sits in Regulation 1603(e)(1): hot coffee and hot bakery goods are technically hot prepared food, but selling them for a separate price is not taxable unless the 80/80 rule, your own tables or a ticketed gate pulls them in. The carve-out ends inside a combo, so selling the coffee and the pastry together for one price makes the whole price taxable.

"Hi! I sell hot food but a lot of customers want it cold to take home and heat up later by themselves. When I sell it hot, it's sales taxable; when I sell it cold, it's not."

— one seller asked on Square's seller community forum in October 2025

That seller has the split right. If the cold version needs heating before it's eaten, Regulation 1603(c)(2) keeps it outside the 80/80 rule, but the register still has to show which version each customer bought. CDTFA's Publication 22 tells sellers who come under the 80/80 rule that the cash register should have a separate key for cold food sold to go, or some other way of identifying those sales, with supporting documents like guest checks and register tapes kept behind it. Before your next shift, I'd get that key set up, whatever your menu looks like.

What is the 80/80 rule, and does it apply to a food truck?

The 80/80 rule applies when more than 80 percent of a seller's total sales are food and more than 80 percent of its food sales are taxable, and when it applies, cold food sold to go becomes taxable unless the seller tracks those sales separately. A truck that sells mostly hot food will usually pass both tests. The two tests come from Regulation 1603(c)(3) and Revenue and Taxation Code section 6359(d)(6).

Sodas and alcoholic beverages are taxable but do not count as food products in either test.

• When both tests pass, cold food sold ready to eat in a one-person size (Regulation 1603(c)(2) gives a large milkshake or a pint of ice cream as examples), plus hot coffee and bakery goods sold at their own price, become taxable even when the order is to go.
• Food the buyer still has to heat, thaw or slice, cold food in containers larger than a pint (milkshakes aside), and party trays stay outside the rule.

A seller who passes both tests can choose to track its cold food sold to go, and its coffee or bakery goods sold to go at their own price, in their own account, and those sales stay tax-free as long as the records show it, under Regulation 1603(c)(1)(A) and Publication 22. Section 6359(f) adds that if the records do not reflect the separate accounting, the election is revoked.

The table below runs the test CDTFA prints in Publication 22 on a hypothetical taco truck's 90 days of sales. I'd run the test on your first 90 days of sales before deciding how to ring up cold items.

Both results clear 80 percent, so the rule applies. Without a separate account, the cold to-go sales in the table become taxable. With tax-included prices at a 10.25% stop such as Santa Clarita or the City of Los Angeles, those sales hold $185.94 of tax, using CDTFA's October 1, 2026 rate table. Tracked separately, they are not taxable and the truck keeps that money. Publication 22 also tells sellers who don't currently qualify to re-run the test every 90 days and keep the records of each test, so treat it as a quarterly habit rather than a one-time calculation.

What sales tax rate does a food truck charge in California?

A food truck charges the full rate in effect where each sale is made, which is California's statewide 7.25% plus any district taxes the city or county adds, per CDTFA's tax-rate information page. District taxes are voter-approved sales taxes that cities, counties and other local areas add on top of the statewide rate, as CDTFA Special Notice L-734 defines them. At a Santa Clarita or City of Los Angeles stop, that comes to 10.25% from October 1, 2026, per CDTFA's October 1, 2026 rate table.

The rate applies whether the tax is included in the menu price or added on top, according to Publication 287. Because a truck moves, the rate can change with the stop: CDTFA's mobile food vendor web page tells vendors, "Since you may be on the move, you are responsible to collect the district tax, if any, at each location where your sales are made throughout the day." CDTFA's Find a Sales and Use Tax Rate tool looks up any stop by address, which is the reliable way to pin down a new location before your first shift there.

On the sales tax return, Schedule A spreads the district tax you collected across the places it belongs to, and Schedule B spreads your sales across the counties where you sold, under CDTFA Special Notice L-734. A stop log is what makes that return possible. If you'd rather not build those schedules yourself, our food truck accounting team tags each stop in the POS and builds Schedule A and Schedule B from that log.

Is sales tax included in a food truck's menu price?

Yes, unless you add a separate tax line, CDTFA presumes the price of a taxable item already includes the tax, under Regulation 1603(v), so the tax comes out of your menu price instead of going on top. At a 10.25% stop, $9.30 of every $100 of tax-included taxable sales is tax. If your truck sells at Los Angeles County stops, I walk through what the October 1, 2026 increase costs a tax-included menu there.

Do food trucks need a seller's permit in California?

Yes. The California Department of Tax and Fee Administration has mobile food vendors register for a seller's permit and report sales tax "as if you were a store or restaurant," in the words of Publication 287. The permit itself is free, though CDTFA can require a security deposit in some cases, according to Publication 73. When CDTFA issues the permit it tells you whether to file monthly, quarterly, quarterly prepay, fiscal annual or annual, and each return is due the last day of the month after the period closes.

For the federal side of a new truck, our federal tax guide for new small-business owners covers income tax, self-employment tax and quarterly estimates, and it applies to a truck the same way.

What happens when a food truck can't prove a sale was tax-free?

The sale gets taxed. Revenue and Taxation Code section 6091 presumes every sale is taxable "until the contrary is established," and puts the burden of proof on the person who made the sale. A sale for resale is a sale to a buyer who resells the item, and a resale certificate from that buyer is what proves it; without one, the seller has to prove the buyer really resold it.

A 2026 opinion from California's Office of Tax Appeals, the state's independent tax appeals body, shows how that plays out. In Appeal of Alcaraz Catering, Inc. (a nonprecedential opinion, so it illustrates rather than sets the rule), an Oxnard company operating 11 food trucks, a commissary kitchen and a catering business had been told in an earlier audit that it needed to collect resale certificates from customers for the sales it claimed were tax-free.

For 2017 the company reported total sales of $1,363,316 and claimed the entire amount as nontaxable sales for resale, reporting zero taxable sales. It filed no sales tax returns for the next three years. In the audit it produced no books and no resale certificates, so CDTFA disallowed all of it and estimated the later years from card-processor records.

The bill came to $660,297 in tax, plus interest and penalties, and the Office of Tax Appeals upheld it because the company's unsupported assertions could not meet its burden of proof. The company's problem was tax-free sales with no paper behind them; a truck's version is cold to-go sales with no separate register key, and for a seller under the 80/80 rule, Publication 22 says that without adequate documentation it owes tax on those sales.

Four ordinary habits keep a truck's tax-free sales tax-free:

• Give every tax-free item its own register key.
• Keep your 90-day test worksheets.
• Take a resale certificate from any business that buys from you to resell.
• Keep invoices that show what an event charge covered.

For the income-tax side, our receipt guide for self-employed owners covers what the IRS expects you to keep, and it applies to a truck the same way.

Do the rules change at festivals, swap meets and private events?

Yes, in two ways. Inside a place that charges admission, everything you sell is taxable; at a private event on the customer's premises, you're catering and a different set of rules takes over.

Food sold within, and for consumption within, a place whose entrance requires an admission charge is taxable, under Regulation 1603(d); "within" means inside the door, gate or turnstile where the ticket is checked. National and state parks are carved out; city and county parks are not. At a festival, fair or swap meet with a ticketed gate, everything a food truck sells is taxable, even the cold sandwich and the bottled water. Park the truck outside the gate and the normal hot/cold rules apply.

When a private party hires you to serve food on their property (a wedding, a company lunch, a backyard party), you're a caterer under Regulation 1603(i)(1), and two things change. First, the rule that treats menu prices as tax-included does not apply to catering. Second, tax applies to the entire catering charge, including the labor of serving, under Regulation 1603(i)(3)(A). I put sales tax on its own line on every event invoice, figured on the whole charge.

Are tips and service charges taxable on a California food truck?

An optional tip or gratuity is not taxable, while a mandatory service charge is included in taxable sales even when every dollar of it goes to your staff. Amounts you report as tip wages to the IRS are presumed optional, under Regulation 1603(h). The same regulation names caterers among the businesses it covers, so on a catering invoice a required service charge is taxable and a tip the client adds by choice is not.

What should you do when you can't tell whether an item is taxable?

Ask CDTFA in writing, describe the facts fully, and keep the written answer. If you rely on CDTFA's written response to your written question, you may be relieved of the tax, penalty and interest if that answer later turns out to be wrong, under Revenue and Taxation Code section 6596. The relief is not guaranteed, the request has to lay out your specific facts, and only the person who asked can rely on the answer.

A real gray area for a truck is seating someone else provides. The regulation taxes food eaten at tables provided by the retailer or by someone the retailer contracts with to serve food, and CDTFA's rules don't say what happens when your customers carry your cold sandwiches to a brewery's patio or a park's picnic tables next to your window. Before making a brewery patio a weekly stop, I'd put that question to CDTFA in writing.
