California sales tax exemptions cover a defined list of goods and buyers: groceries bought for home consumption, prescription medicines and prescribed medical devices, utilities delivered through pipes or wires, certain agricultural inputs, digital products delivered without physical media, purchases for resale, goods shipped out of state, direct sales to the U.S. government, specific nonprofit and school sales, and casual one-time sales. Manufacturing and research equipment gets a partial exemption rather than a full one. Most exemptions require the buyer to give the seller a properly completed resale or exemption certificate at the time of sale.
What’s Exempt When You Buy It
The exemption most Californians use every week is for food. Revenue and Taxation Code Section 6359 exempts grocery-type items: produce, meat, dairy, canned goods, cereal, coffee, and most non-carbonated beverages including juice and bottled water. Alcohol and carbonated drinks are taxable. The exemption also disappears once food is sold hot, served for on-site eating with tables or counters, or sold at a location with parking set aside for customers to eat there. A to-go order from a drive-through can be taxable if the location has designated eating areas with parking.1California Legislative Information. California Code RTC 6359 – Food Products
Prescription medicines are exempt when prescribed by an authorized professional and dispensed by a licensed pharmacist, or furnished directly by a physician, dentist, or podiatrist to a patient. Medicines sold to hospitals, health facilities, and state or local government entities for patient treatment also qualify.2California Department of Tax and Fee Administration. California Revenue and Taxation Code 6369 – Prescription Medicines Section 6369’s definition of “medicines” excludes prosthetic devices, orthotic devices, hearing aids, and ophthalmic appliances, but those are picked up under a separate framework. CDTFA Regulation 1591 exempts prosthetics, orthotics, artificial limbs, and related prescribed medical devices.3California Department of Tax and Fee Administration. Regulation 1591 – Medicines and Medical Devices The practical result is that both prescribed drugs and prescribed devices are exempt, just under different provisions.
Utility services delivered through mains, lines, or pipes are exempt. That covers gas, electricity, water, steam, geothermal steam, and related heat energy, along with liquefied petroleum gas delivered to a primary residence not served by gas mains (into a tank of at least 30 gallons) and propane used in agricultural production.4California Legislative Information. California Code RTC 6353 – Gas, Electricity, and Water One boundary: this is a sales tax exemption only. Cities and counties can still impose a separate utility users tax.
Agricultural inputs tied to food production or commercial sale are exempt under Section 6358. The list includes livestock whose products ordinarily become human food, feed for those animals or for animals sold in the regular course of business, seeds and plants whose products ordinarily become human food or that are sold commercially, fertilizer applied to land producing food or commercial crops, and veterinary medicines (including oxygen) used primarily to prevent or control disease in food-producing livestock.5California Legislative Information. California Code RTC 6358 – Agricultural Exemptions Seeds for a home flower bed don’t qualify, because the products are neither food nor sold commercially.
Software, eBooks, apps, digital images, and similar electronic products transmitted entirely over the internet, with no physical storage medium changing hands, are generally not taxable. The exemption turns on delivery method. A download or stream is non-taxable. The same product shipped on a flash drive or disc is taxable, and if a seller provides both a download and a physical backup copy, the entire sale becomes taxable.6California Department of Tax and Fee Administration. Internet Sales Publication 109 – Nontaxable Sales Cloud-based software follows the same logic because no tangible property transfers to the customer.
Exemptions Based on Who’s Buying or Why
California sales tax is meant to hit the final retail sale, so purchases of inventory for resale are exempt. The buyer gives the seller a resale certificate at the time of purchase, and tax is collected later when the end customer buys the product. The exemption applies whether the item will be resold on its own or incorporated into another product the buyer sells.7Taxes.ca.gov. Resale Certificates
Goods shipped out of California as part of the sale are generally exempt. The sales contract itself has to call for out-of-state delivery, and the seller must ship using its own vehicles or a common carrier, customs broker, or forwarding agent. A buyer who takes possession in California and drives the goods across the border doesn’t qualify.8California Department of Tax and Fee Administration. Regulation 1620 – Interstate and Foreign Commerce For exports, the property must be irrevocably committed to the export process at the time of sale and actually delivered abroad before anyone uses it.
Direct sales to the United States government and its agencies are exempt under Section 6352, which carves out property California is constitutionally or federally prohibited from taxing.9California Legislative Information. California Code RTC 6352 – Exemptions The exemption stops at the government itself. A private contractor working on a federal project is treated as the end consumer of materials and fixtures it installs, and owes sales tax on those purchases.10California Department of Tax and Fee Administration. Sales to the United States Government Publication 102 – Federal Contractors
Nonprofit status, by itself, does not exempt an organization from sales tax. Churches, charities, and educational groups owe tax on retail sales and purchases like anyone else.11California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 165.0000 Charitable Organizations Two narrow exemptions do exist. Meals and food products served to students by public or private schools, school districts, student organizations, and parent-teacher associations are exempt, though the exemption does not reach food sold at events with paid admission (except at national and state parks). And charitable organizations that qualify for the welfare exemption under Section 214 and work to relieve poverty may sell goods they have made, prepared, or assembled without charging sales tax, as long as the sales themselves function as charitable assistance to the buyer.12California Department of Tax and Fee Administration. California Revenue and Taxation Code 6375 – Sales by Charitable Organizations
Casual sales fall outside the tax entirely. Section 6367 exempts occasional sales made outside the regular course of business, which is what keeps garage sales and one-time sales of used personal property from triggering a seller’s permit requirement.13California Department of Tax and Fee Administration. California Revenue and Taxation Code 6367 – Occasional Sales The exception that catches people off guard: vehicles required to be registered with the DMV, along with vessels, aircraft, and mobilehomes subject to annual registration, remain taxable no matter how infrequently you sell them.
The Manufacturing and R&D Partial Exemption
Businesses primarily engaged in manufacturing, research and development, or electric power generation can claim a partial exemption on qualifying machinery and equipment under Section 6377.1. The exemption runs from July 1, 2014 through June 30, 2030, with the statute set to be repealed on January 1, 2031.14California Legislative Information. California Code RTC 6377.1 – Manufacturing, Power Generation, and Research and Development Equipment
The word “partial” matters. The exemption eliminates the state portion of the sales tax but leaves local district taxes in place, so the effective rate on qualifying purchases comes to 3.3125% plus any applicable district taxes.15California Department of Tax and Fee Administration. Manufacturing and Research and Development Exemption Tax Guide Three conditions all have to be met: the buyer must be a “qualified person” primarily engaged in manufacturing or R&D, the purchase must be “qualified tangible personal property” (essentially machinery and equipment used in the production process), and the buyer must use the property in a qualifying way.16California Department of Tax and Fee Administration. Tax Guide for Manufacturing, Research and Development, and Electric Power Equipment and Buildings Exemption There is also a cap: the exemption applies only to the first $200 million in qualifying purchases per calendar year, and for companies filing combined reports the cap covers the whole group.14California Legislative Information. California Code RTC 6377.1 – Manufacturing, Power Generation, and Research and Development Equipment
How to Claim an Exemption
The burden of proving a sale is exempt sits with the seller. Without proper documentation, the seller owes the tax. Two documents do most of the work: the resale certificate for purchases of inventory, and an exemption certificate for exemptions tied to the buyer’s identity or the item’s end use (government buyers, qualifying nonprofits, manufacturers claiming the partial equipment exemption, and so on).
A valid resale certificate has to include the purchaser’s name and address, seller’s permit number, a description of the property being purchased, an explicit statement that the purchase is for resale, the date, and the purchaser’s signature.7Taxes.ca.gov. Resale Certificates A seller who accepts a resale certificate in good faith is shielded from liability even if the buyer later misuses the property. Good faith here means the certificate came from someone who plausibly appears to be in the business of selling the type of property described and who holds a valid seller’s permit.17California Legislative Information. California Revenue and Taxation Code 6092 Sellers should keep every certificate on file.
Penalties for Misusing a Resale Certificate
Issuing a resale certificate to avoid tax on something you don’t actually plan to resell is a direct violation. The buyer owes the full tax that would have been due, plus a penalty of 10% of the tax or $500, whichever is greater, for each improper purchase. The rule reaches individual buyers as well as corporate officers or employees who issue certificates on behalf of a business.18California Department of Tax and Fee Administration. California Revenue and Taxation Code 6094.5
Penalties stack. If the buyer also fails to report and pay the use tax owed on the property, a 10% negligence penalty or a 25% fraud penalty applies on top of the original fine, with interest accruing from the date the tax was originally due.19Legal Information Institute. California Code of Regulations Title 18 Section 1668 – Sales for Resale CDTFA audits regularly catch these mismatches by comparing purchase records against reported resales.
