Is labor to sell and install a car stereo system taxable, and does the answer change if the stereo is later repaired or if the installation involves remodeling the vehicle?

Plain-English summary

A business that sells and installs car stereo systems asked whether the installation labor on its invoices is exempt from sales tax. The Comptroller's answer turns on exactly what job is being done:

• Selling and installing a stereo you sold: the installation labor is taxable as part of the total sales price for the stereo, even if you bill materials and labor as separate line items.
• Installing a customer's own stereo (you didn't sell it): the installation labor is not taxable, because it isn't connected to a sale of tangible personal property.
• Repairing a broken or defective stereo: the repair labor is never taxable. Whether the parts are taxed depends on billing — a lump-sum price for parts and labor together means the repairman pays tax on the parts as the consumer (and collects nothing from the customer); separately stating parts from labor means the repairman must hold a sales tax permit and collect tax on the parts (but not the labor), and may buy those parts tax-free with a resale certificate.
• Remodeling the vehicle (changing its style, shape, or form — e.g., cutting out the back seat or modifying the trunk to fit a sound system): the entire charge, parts and labor combined, is taxable.

What this means for you

Car stereo/audio installers

If you sell the stereo and install it, tax the whole invoice — parts and labor together. If you're hired only to install a stereo the customer already owns, you don't need to collect tax on your installation labor. Keep clear records of which situation applies to each job, since the tax treatment flips entirely based on who sold the equipment.

Auto shops doing stereo repairs

Decide upfront whether you'll bill lump-sum or itemized. Lump-sum means you're the taxable consumer of the parts (you pay tax when you buy them, collect nothing extra from the customer). Itemized means you need a sales tax permit, must collect tax on the parts portion, and can buy those parts tax-free with a resale certificate — but the labor portion stays untaxed either way, as long as it's genuinely a repair and not a sale-and-install.

Shops doing custom vehicle modifications

Watch for the remodeling trap: if the job changes the vehicle's shape or form (not just replacing/adding an accessory), the Comptroller treats the whole job — parts and labor — as taxable, with no separate exempt-labor carve-out.

Common questions

Q: I sell and install car stereos. Is my installation labor taxable?
A: Yes, when you're also the seller of the stereo — the labor is part of the total taxable sales price.

Q: What if I'm only installing a stereo the customer already owns?
A: That installation labor is not taxable, because it's not tied to a sale of the stereo itself.

Q: Is repairing a broken car stereo taxable?
A: The repair labor itself is never taxable. Tax on the parts depends on whether you bill a lump sum (you pay tax as the consumer, collect none from the customer) or separately state parts and labor (you collect tax on the parts only, and can buy those parts tax-free for resale).

Q: What counts as "remodeling" a vehicle for this purpose?
A: Changing the vehicle's style, shape, or form — the letter gives the example of removing the back seat or modifying the trunk to fit a car stereo sound system. Remodeling makes the entire charge (parts and labor) taxable.

Q: Can I rely on this letter for my own business?
A: No. This opinion is based on the facts presented to the Comptroller; additional or different facts could change the answer.

Subject: Sales tax for installer of auto accessories

I am responding to your e-mail of April 20, 2000 regarding the taxability of
the sale and installation of accessories to motor vehicles.

You sell and install car stereo systems. You separate the bill listing the
materials and labor. You want to know if the labor is exempt from sales tax.

Rule 3.290 (b) states: Except when replacing a defective or inoperative
component or accessory, a person engaged in the sale and installation of motor
vehicle component parts and accessories must collect sales tax on the price
charged for the parts, accessories, and installation. The removal and
replacement of defective, worn, or unsafe accessories or components is a repair
and not a sale and installation.

The installation labor is taxable as part of the total sales price for the car
stereo if billed to a customer by the car stereo seller. On the other hand, an
installer who is only installing the customer's own car stereo does not need to
collect sales tax on the installation labor. In that case, the installation
labor is not connected to the sale of the car stereo. Persons selling car
stereos may give a resale certificate for car stereos they sell and collect tax
on.

Sometimes a broken or defective car stereo needs repair or replacement. This is
considered a repair of the motor vehicle. The labor to repair a motor vehicle
is not taxable. Sales tax on the repair parts are handled differently depending
on the type of billing (lump sum or separated) to the customer. If the
repairman has a single price that includes both parts and labor, the repairman
is the consumer of all parts and must pay tax when purchasing the parts from
suppliers. No sales tax is collected on the lump-sum price for the repair. If
the repairman separately states charges for parts from charges for labor, the
repairman must get a sales tax permit and collect sales tax from the customer
on the charge for parts, but not the charge for labor. A repairman who
separately states charges for parts and labor may give a resale certificate for
parts they collect tax on.

The remodeling of a motor vehicle is taxable. Sales tax must be collected on
the total charge including parts and labor. Remodeling means the style, shape,
or form of the motor vehicle is being modified. For example, removing the back
seat or modifying the trunk of a motor vehicle so that it is replaced with a
car stereo sound system is remodeling.
