“Do I charge tax on labor?” has a different answer in every state, and getting it wrong costs you either way: overcharge and you owe what you collected, undercharge and you owe what you didn’t. Here’s how three large states treat auto repair, straight from their tax agencies, plus invoicing habits that keep you safe anywhere.

Three states, three answers

	Texas	California	New York
Repair and maintenance labor	Not taxable	Generally not taxable (listed separately)	Taxable
Parts	Taxable	Taxable	Taxable
How invoicing affects it	Lump-sum vs separated invoice changes who pays the tax	Labor must be on a separate line	Tax on the total charge for parts and labor
Tools and equipment you buy	You pay tax	You pay tax	You pay tax

Texas

The Texas Comptroller says: “There is no sales tax on the labor to repair a motor vehicle.” Its examples are repairing or replacing a tire, battery, muffler or shock absorber. Parts are taxable, and how you invoice decides who pays (Texas Comptroller, Pub. 94-113):

Separated invoice: itemize parts and labor, collect tax on the parts, and buy the parts tax-free with a resale certificate. The Comptroller’s example: a $20 labor plus $49.95 parts oil change, with tax collected only on the $49.95.
Lump-sum invoice: one price for parts and labor. Don’t collect tax from the customer; pay tax to your supplier when you buy the parts. The Comptroller’s example is a $69.95 lump-sum oil change.
Remodeling and accessories are different. Tax is due on all parts and labor for remodeling (body kits, lift kits, performance upgrades) and for selling and installing accessories like stereos and alarms. Replacing a defective component is a repair, not a remodel.
Tools and equipment: you’re the end consumer, so you pay tax when you buy them and can’t charge customers tax on them.

California

The California Department of Tax and Fee Administration (CDTFA) says charges for labor and services are generally not taxable, and you must list labor on a separate line of the invoice (CDTFA, Tax Guide for Auto Repair Garages).

Nontaxable labor includes repair labor, installation labor on used vehicles, maintenance services (tune-ups, oil changes, fluid flushes) and services such as charging batteries.
Taxable labor includes fabricating or modifying parts as part of a taxable sale, and installing parts on new vehicles.
Core charges on new or used parts are taxable, even if refunded. For rebuilt parts, tax applies to the exchange price when the core is refunded.
Lead-acid batteries: you must charge a refundable deposit when a customer buys a new replacement battery without handing over a used one. Refund the deposit if a used battery of the same type comes back within 45 days. The deposit is taxable, and that tax isn’t refunded.
Supplies you use yourself, such as rags and tools, are taxable to you. CDTFA asks you to keep records for at least four years.

New York

New York is the opposite of Texas on labor. Its Tax Bulletin ST-40 says that “in general, most charges by a repair or body shop are taxable.” You must collect sales tax on the total charge for parts and labor, and you must be registered to collect it (NY Tax Dept., TB-ST-40).

Parts and supplies transferred to the customer (brake pads, filters, belts, motor oil, brake fluid, antifreeze) can be bought tax-free with Form ST-120, a resale certificate.
Shop supplies not transferred to the customer (shop towels, cleaners, floor mats, sandpaper, masking tape) and tools and equipment (wrenches, impact tools, jumper cables, lifts, air compressors) are taxable when you buy them.
Towing a disabled vehicle is taxable, and so is vehicle storage. (California lists towing as a nontaxable service, which shows how much states differ.) The charge for a New York State inspection itself is not, but repairs needed to pass it are.
Warranty work billed to a registered warranty company that gives you Form ST-120 isn’t taxable. Charges billed to the customer are.

Invoicing habits that work in any state

Register before your first sale if your state requires it. New York, for example, says repair shops must be registered to collect and remit sales tax (TB-ST-40).
Itemize parts and labor on every invoice. California requires a separate labor line, Texas makes it the basis for who pays, and in New York it supports your records. The free estimate & invoice generator splits them for you, and shop software can apply tax rules per line.
Use resale certificates for parts you resell, not for tools or shop supplies you use up.
Watch the rate where you work. A mobile mechanic works in many cities and counties. Use your state’s address-based rate lookup and ask your CPA which location’s rate applies.
Keep records. CDTFA’s minimum is four years. See also bookkeeping in the startup checklist.

Sales tax you collect isn’t your income, so leave it out of your labor rate math. Price before tax and show tax separately.
