Texas Comptroller Upholds Construction Services Sales Tax

Texas sales tax law has never been famous for being a gentle bedtime story, and a recent Texas Comptroller decision did not exactly tuck anyone in. Instead, it sent a very clear message to contractors, developers, property owners, and accounting teams: if you mix taxable construction-related services with nontaxable work in one big lump-sum charge, Texas may happily treat the whole thing as taxable unless you can prove otherwise.

That is the real story behind the headline “Texas Comptroller Upholds Construction Services Sales Tax.” The decision did not suddenly make every construction service in Texas taxable. Far from it. Texas still treats new construction differently from repair and remodeling, and it still treats residential work differently from nonresidential work. But the ruling reinforces something contractors learn the hard way every audit season: the tax result often turns on how the job is classified, how the contract is written, and whether the paperwork can survive an uncomfortable amount of scrutiny.

If that sounds dramatic, it is. In Texas tax law, your scope-of-work schedule can matter almost as much as your concrete schedule.

What Happened in the Texas Comptroller Decision?

The case involved construction services performed between 2014 and 2017 under contracts that covered a mix of new construction, repairs, and remodeling. The taxpayer argued that some of the work should have been treated as nontaxable. The Comptroller, and later the administrative law judge, disagreed because the taxpayer had used a single lump-sum charge that bundled taxable and nontaxable services together.

That detail is the whole brisket here. When a contract combines taxable and exempt or excluded work into one undivided charge, Texas does not automatically let the taxpayer come back later and say, “Trust us, a decent chunk of that was the good kind of construction.” The state wants contemporaneous proof, not after-the-fact optimism.

In plain English, the ruling says this: if your contract rolls everything into one price and your records do not clearly separate taxable work from nontaxable work, the Comptroller can assess sales tax on the charge. That is especially true when the taxable portion is more than a minor side dish. Under Texas rules, if taxable services in a mixed charge exceed 5% of the total and are not properly separated or supported, the whole charge can be presumed taxable.

Texas Construction Sales Tax Rules, Explained Like a Normal Human

Texas does not tax construction services with one giant brush. The state uses categories, and those categories matter a lot.

New construction is generally excluded

Texas generally excludes new construction from sales tax. That includes original construction and certain initial finish-out work. So if a contractor is building new usable square footage, that labor is usually in the nontaxable camp. This is where many taxpayers exhale, assume everything is fine, and then walk straight into the next problem.

The problem is that not every project called “construction” is legally new construction. Expanding a building outward may qualify. Reworking an already occupied interior often does not. If you are remodeling an existing office floor, renovating a restaurant kitchen, or updating a commercial lobby, Texas may see that as taxable nonresidential repair or remodeling, not new construction with a hard hat and a better attitude.

Residential repair and remodeling are generally treated better

Texas is kinder to residential repair and remodeling labor. If the work is performed on residential real property, labor is generally not taxable. That covers a lot of normal homeowner activity, such as remodeling kitchens, replacing built-in fixtures, and restoring damaged areas in homes or apartments.

But even here, do not let the tax fairy tale get too dreamy. The tax treatment of materials can still depend on whether the contract is lump-sum or separated. A contractor might pay tax on materials when buying them, or collect tax on material charges when those are separately stated. So “residential” does not mean “ignore accounting forever.” Nice try, though.

Nonresidential repair and remodeling are where the heat lives

For existing nonresidential property, Texas generally taxes the total charge for repair, restoration, and remodeling services. That means commercial buildings, office towers, warehouses, refineries, retail stores, restaurants, and similar properties live in the danger zone.

This is the rule that surprises people who assume labor is automatically exempt because the work “feels construction-y.” Texas does not care how heroic the project manager’s headset looked on site. If the job is repair or remodeling of existing nonresidential real property, sales tax generally applies.

Why Lump-Sum Contracts Cause So Much Trouble

Texas tax treatment often turns on whether a contract is lump-sum or separated. Under a classic lump-sum contract, the customer gets one total price for labor and materials. Under a separated contract, labor and incorporated materials are separately stated.

For many construction jobs, that distinction can change who pays tax, when tax is paid, and whether resale treatment is available for materials. But for nonresidential repair and remodeling, Texas has made clear that the old distinction between lump-sum and separated contracts does not rescue the contractor from tax on the service itself. The total charge is generally taxable either way.

Where lump-sum contracts become especially dangerous is in mixed projects. Imagine a contract that covers:

• an addition that qualifies as new construction,
• a remodel of existing commercial space, and
• some unrelated nontaxable services.

If that whole package is billed as one number, Texas can presume the charge is taxable when the taxable portion is more than 5% of the total. The taxpayer may overcome that presumption, but only with strong documentary evidence. In other words, it is possible, but nobody wins style points for trying to reconstruct the project from coffee-stained spreadsheets three years later.

Examples That Show How This Works in Real Life

Example 1: Restaurant expansion plus kitchen remodel

A restaurant owner hires a contractor to add a brand-new enclosed patio and also rework the existing kitchen. The new patio likely falls under new construction. The kitchen rework inside the existing building is likely taxable nonresidential remodeling. If the contractor bills one all-in amount and does not clearly separate the charges, the entire contract may be taxed.

Example 2: Apartment renovation versus hotel renovation

An apartment complex is generally treated as residential property. Labor to repair or remodel those units is generally not taxable. A hotel, however, does not receive the same treatment because it is not treated as residential property in this context. Same drywall dust, very different tax result.

Example 3: Generator installation

Texas guidance on generators highlights the line beautifully. Installing a generator in new or existing residential property or in new nonresidential property can fall under contractor rules where labor is not taxed the same way. Installing it in an existing nonresidential building, however, is generally treated as a taxable real property improvement, and the service provider should collect tax on both labor and materials.

Example 4: Job-site sourcing

Local tax can also matter. Texas state sales tax is 6.25%, but local jurisdictions can push the combined rate to 8.25%. For nonresidential repair and remodeling services, the local tax implications may depend on the job-site location. So even if a contractor classifies the work correctly, using the wrong local rate can still produce an audit headache with extra paperwork for dessert.

What the Ruling Means for Contractors and Developers

This decision matters because it reinforces four uncomfortable truths.

1. Texas cares about the exact nature of the work

Calling a job “construction” is too broad to be useful. Texas wants to know whether the work is new construction, repair, restoration, remodeling, or maintenance. That classification drives the tax result.

2. Texas cares about the kind of property involved

Residential and nonresidential property are treated differently. A contractor who handles both can end up with two totally different tax outcomes on jobs that look similar to the naked eye.

3. Texas cares about how the contract is written

A beautiful invoice cannot fix a sloppy contract. If the agreement does not separate taxable and nontaxable labor where it should, the state may default to taxing the whole thing.

4. Texas cares about contemporaneous records

That means records created in the normal course of business while the job is happening: written contracts, bid sheets, scope documents, schedules of values, blueprints, work orders, and similar proof. If you have to create your explanation only after an audit starts, you are already negotiating from the back foot.

How to Reduce Sales Tax Risk on Texas Construction Projects

1. Classify the job before the first invoice goes out. Decide whether each portion is new construction, residential repair/remodeling, nonresidential repair/remodeling, or maintenance.
2. Break mixed jobs into clear components. If a project includes both taxable and nontaxable work, separate them in the contract and in billing.
3. Keep backup that actually matches the allocation. Scope descriptions, bid sheets, takeoffs, schedules of values, and blueprints should support the numbers used.
4. Train operations and accounting together. Project managers know the work. Accountants know the tax return. Both sides need to speak the same language before the audit begins speaking for them.
5. Review local tax sourcing. State tax may be straightforward, but local tax mistakes can quietly eat profit margins.
6. Do internal spot checks. A small self-audit now is much cheaper than a formal audit later, especially when the state brings interest and penalties to the party.

Common Mistakes Businesses Make

The most common mistake is assuming every part of a project inherits the tax treatment of the “main” work. That is not always true. A contract can include taxable remodeling of an existing structure and nontaxable new construction in the same project.

The second big mistake is trusting invoices to do the work the contract never did. If the signed agreement is one giant price, later invoices that try to carve out tax-free portions may not save the taxpayer.

The third mistake is weak recordkeeping. Contractors often keep enough information to build a building, but not enough to explain the tax treatment of each phase three years later. The Comptroller, unhelpfully but predictably, prefers both.

Experience From the Field: What This Issue Feels Like in Practice

One of the most common real-world experiences around Texas construction sales tax starts in estimating, not in accounting. A contractor wants to win a job, the owner wants one clean number, and everyone agrees that a lump-sum bid is simple. It feels efficient. Nobody wants to slow the deal down by slicing the project into taxable and nontaxable categories. Then the project closes, the invoices are paid, and three years later the company is trying to remember whether the “Phase Two buildout” included an addition, an interior demolition, or a little bit of everything. At that point, “simple” has become very expensive.

Controllers and CFOs also describe a familiar pattern: operations teams speak in construction language while tax teams speak in statute language. The superintendent says, “We added a new space.” The tax department asks, “Was it new usable square footage, or was it a reallocation inside an existing structure?” The field team says, “We upgraded the mechanical area.” Tax asks, “Was that restoration, maintenance, or support work incidental to new construction?” Both sides are talking about the same project, but unless those details make it into the contract and the backup files, the audit record may never tell the full story.

Another common experience comes from mixed commercial projects. Think of a retail center where the contractor adds a new exterior pad site, remodels several occupied suites, and performs punch-list work in common areas. In the field, it feels like one big job. In Texas sales tax terms, it may be several different buckets with several different rules. Contractors who keep bid sheets, schedules of values, and drawings that map to each bucket often have a far easier time defending their treatment. Contractors who bill everything under “improvements per proposal” usually have a rougher week when the audit notice arrives.

Subcontractors have their own version of this headache. Many assume the prime contractor’s tax treatment automatically controls the subcontract. It does not always work that way. A prime may have one contract structure, while subs have another. If the subcontractor does not understand how its own work is classified, it can under-collect tax, overpay tax, or create a mismatch that confuses everyone from AP clerks to outside auditors.

There is also the emotional experience nobody puts in the project closeout file: frustration. Businesses often feel they did real, productive construction work and cannot understand why Texas is so focused on wording, categories, and percentages. But that is exactly how tax disputes develop. In this area, the paperwork is not separate from the project. The paperwork is part of the project. The companies that handle this best are usually not the fanciest. They are the ones that build a repeatable process where contracts, billing, and job-cost records all tell the same story at the same time.

Final Takeaway

The Texas Comptroller’s ruling is not a broad declaration that all construction services are taxable. It is something more precise and, for many businesses, more dangerous. It confirms that mixed construction contracts with taxable and nontaxable components can become taxable in whole when the taxpayer uses a single charge and cannot substantiate the split.

For Texas contractors, developers, and property owners, the lesson is simple: classify the work correctly, document it while it is happening, and do not assume a lump-sum contract will magically protect nontaxable portions of a project. Texas tax law is many things, but magical is not one of them.
