Texas sales tax on electrical contracts

The property type decides who owes the tax, not the trade

Ask five electrical contractors how Texas sales tax works and you'll get five different half-right answers, because the real rule hinges on a distinction most people never learn: what kind of property you're working on, not what trade you're in. Wiring a new office building and rewiring an existing one sit on opposite sides of a hard line. New construction is treated as an act of building, and the labor on it is not taxed as a service at all. Repairing, remodeling, or restoring a nonresidential structure that already exists is a different category entirely — the whole charge for that job is a taxable service under Texas law. Your license (see electrical contractor license) says nothing about which side of that line a given job falls on; the property's condition and the scope of the work do. Get the category wrong on a bid and you've either overcharged your customer or left a tax bill for yourself to discover later.

New construction escapes the sales tax on labor entirely

Building a new structure, completing one that's unfinished, or doing the initial finish-out on a structure's interior or exterior is new construction, and Texas does not tax the labor on any of it — lump-sum or separated makes no difference to that part. What is still taxable is the panel, the wire, the breakers, and every other piece of tangible property you install. As the contractor, you're treated as the consumer of those materials: you pay sales tax to your supplier when you buy them, exactly like any other purchase for your own use, and you do not add a separate tax line to the customer's invoice for labor or materials. That holds whether you're wiring a spec house, a new retail build-out, or a ground-up commercial shell. The moment the structure is finished and occupied, any later work on it drops out of new construction and into the repair-and-remodel rules — a different tax posture entirely.

Repairing or remodeling nonresidential property is taxable

Once a nonresidential structure exists and is in use — an office, a warehouse, a retail shop, a clinic — work on it stops being construction and starts being a taxable service. Rewiring a breaker panel, adding circuits for new equipment, replacing damaged conduit: all of it falls under remodeling, repairing, or restoring, and the total amount you charge for that job is taxable. This is the opposite of new construction, where labor escapes tax outright, and it's the distinction an auditor checks first when reviewing a contracting business's invoices. The mechanics of how that tax actually gets collected — who pays it and on what — depend on a second choice you make when you write the contract: whether it's priced as one lump sum or with materials and labor broken out separately. That choice, not the job itself, decides whether you or your customer ends up remitting the tax.

Lump-sum contracts make you the consumer of the materials

Price the job as one number — parts and labor together, no breakout — and Texas treats you as the end consumer of everything you install. You pay sales tax to your supplier when you buy the wire, the panel, the fixtures, the same as if you were buying them for your own shop. You do not separately state or collect tax from your customer on that lump-sum price, even on a nonresidential repair job where the labor would otherwise be taxable. The tax obligation on the materials is satisfied at your purchase, once, and that's the end of it. The tradeoff is that you can't buy those materials tax-free with a resale certificate — that option belongs to separated contracts only. For a small job where itemizing invites more questions than it answers, lump-sum pricing is often the simpler route, and it's the one a lot of residential and light commercial work still uses by default.

Separated contracts make you a seller who collects tax

Break the invoice into a materials line and a labor line, and the tax mechanics flip. You give your supplier a resale certificate instead of paying tax on the materials at purchase, because you're not the end consumer anymore — you're reselling those materials to your customer as part of the job. You then collect Texas sales tax, plus whatever local tax applies, from the customer on the amount you charged for materials. On a nonresidential job, where the whole service is taxable, that collection extends to the labor charge too, not just the materials. The upside is cash flow: you're not fronting tax on inventory before you've been paid. The downside is paperwork — a resale certificate on file for every supplier, tax computed on every invoice, and a contract that has to actually itemize the split in writing, not just imply it. An auditor who can't find that itemization treats the whole job as if it were never separated at all.

Residential work follows its own, narrower rule

Everything above changes shape on a house. Labor to repair or remodel residential real property — a single-family home, an apartment unit, a nursing home, a condo — is not subject to Texas sales tax, regardless of whether the owner actually lives there. That's the opposite default from nonresidential work, where labor on a repair job is taxable. A lump-sum residential job works the same as any other lump-sum job: you pay tax on materials as the consumer and charge the customer nothing extra. A separated residential job also mirrors the general pattern on materials — resale certificate to your supplier, tax collected from the customer on the materials line — but because residential labor is exempt, you never add tax to the labor line, itemized or not. Mixing that up on a duplex or a live-work unit, where residential and nonresidential space share one address, is a common way this goes wrong.

A resale certificate is a promise you have to keep

You may only issue a resale certificate to a supplier when you're actually going to resell what you're buying — incorporating it into a customer's property under a separated contract, where you'll collect the tax back from them. Issue one on a lump-sum job, or on materials you end up using for something else, and you haven't avoided the tax — you've just moved who owes it. The liability shifts from your supplier collecting it at the register to you owing it directly, self-assessed the way any underpaid tax is, with the same penalty and interest that applies to a late payment on any other report. Auditors treat a resale certificate on file for a job with no matching tax collected from the customer as exactly this kind of mismatch, and it's one of the easier ones to find in a stack of invoices.

The sales tax permit costs nothing and sets your filing schedule

You need a Texas sales and use tax permit before you collect a dollar of tax from a customer, and the application itself carries no fee — you'll need the business entity you already set up (see business setup) in hand, since the form asks for your EIN or Social Security number, your NAICS code, and, for a corporation, its Secretary of State file number. Budget two to three weeks for the permit to arrive after you apply online. Once it's issued, the Comptroller assigns you a filing frequency — monthly, quarterly, or yearly — based on how much tax you're actually collecting; a busier shop reports more often, a slower one less. Miss a due date and the report itself draws a flat penalty on top of whatever tax and interest is owed, whether the amount involved was large or small, so the filing habit matters as much as getting the tax rule right in the first place.

Local rates stack on the state rate, up to a cap

The state charges 6.25% on every taxable sale or service, and that's before your city, county, transit authority, or special district adds its own piece on top. Those local add-ons are capped: combined, they can't push the total more than 2 percentage points over the state rate, so 8.25% is the ceiling anywhere in Texas, no matter how many local jurisdictions overlap at a job site. Which local rate actually applies depends on where the taxable item is delivered or the service is performed, not on your shop's address, which matters if you work across county lines. The municipal permit your job needs (see municipal licensing and permits) is a separate process from this tax entirely — one is the city letting you do the work, the other is the state getting paid for it — and confusing the two is a common paperwork mix-up.

What a sales tax audit is actually looking for

A sales tax audit on a contracting business is rarely a hunt for a missing receipt. It's almost always a review of how jobs were characterized — lump-sum against separated, new construction against repair — because that characterization is what decided whether tax was owed at all, and it's the easiest place for an honest contractor to have guessed wrong months or years earlier. An auditor pulls contracts and invoices and checks whether the paperwork actually supports the treatment you used: a separated contract with no itemization, a resale certificate with no matching tax collected, a repair job billed and taxed like new construction. This obligation runs alongside your other state filings, not instead of them — sales tax is separate from the franchise tax and annual report your entity owes every year (see franchise tax and annual reports) — and an audit of one sometimes surfaces gaps in the other. Keeping contract language consistent with how you actually billed the job is the easiest way to stay out of that conversation.
