Here’s the frustrating answer: it depends on where the hammer swings.
In most states, contractor labor isn’t taxable. But “most” covers a lot of ground, and the exceptions (certain states, certain projects, certain contract types) are exactly where businesses get blindsided. Whether you’re a contractor pricing multi-state jobs or a business owner trying to decode an invoice, here’s what you need to know.
Hands Off Sales Tax (HOST) specializes in untangling exactly this kind of complexity. Figuring out where tax applies, getting you registered, and keeping filings current so nothing falls through the cracks.
The Default Rule (and Why It Has So Many Asterisks)
In most states, sales tax targets tangible goods like lumber, pipe, or fixtures. Labor is a service, and services are generally exempt. So a typical contractor pays sales tax when buying materials, folds that cost into their pricing, and doesn’t add a separate tax line for labor on the customer’s invoice.
Simple enough. But the following factors can flip that default:
- Which state: a handful tax services broadly or have contractor-specific taxes
- New construction vs. repair: new construction labor is nearly universally exempt; repair, maintenance, and remodeling work is where states diverge
- Residential vs. commercial property: several states tax labor on commercial work while exempting the same labor on a home
- How the contract is written: lump-sum vs. time and materials can shift who owes tax and when
The Residential vs. Commercial Split
Before getting into specific states, there’s a pattern worth naming because it shows up repeatedly: the same work, done by the same contractor, in the same state, is taxable on a commercial building and exempt on a residential one.
Texas is the clearest example. Per the Texas Comptroller, labor to repair, remodel, or restore residential real property is not taxable — neither is new construction. But the total charge for repairing or remodeling nonresidential or commercial property is fully taxable (labor and materials) regardless of whether you’re using a lump-sum or separated contract. A contractor remodeling an apartment pays no tax on labor; the same contractor remodeling the retail space next door collects tax on everything.
Kansas follows a similar split. Per KS DOR Publication KS-1525, labor on residential construction is generally exempt, while commercial remodeling labor is taxable. Connecticut ties taxability to whether the property is owner-occupied residential (exempt) or existing commercial/income-producing (taxable). The pattern repeats often enough that it’s worth making the residential vs. commercial question your first stop when evaluating a job.
States Where Labor Is Taxable (or Has a Special Tax)
Hawaii
Hawaii skipped sales tax entirely and built something more pervasive: the General Excise Tax (GET), which applies to virtually all business activity, construction included. The base state rate is 4%, and all four counties: Honolulu, Hawaii, Kauai, and Maui layer on a 0.5% surcharge, bringing the effective rate to 4.5%. The GET is technically the contractor’s liability, not the customer’s, but most contractors pass it through on the invoice.
New Mexico
New Mexico’s Gross Receipts Tax (GRT) applies to the contractor’s revenue from the job, including labor. Some deductions exist for specific project types like hospitals and low-income housing, but construction services are taxable by default.
South Dakota
South Dakota contractors owe a 2% Contractor’s Excise Tax on gross receipts from realty improvement projects under SDCL 10-46A. Not a traditional sales tax, but close enough in practice. Most contractors pass this cost along as a line item on the invoice, which state law permits.
West Virginia
West Virginia taxes construction services, both labor and materials, at a 6% rate by default. The exemption is for capital improvements, which must meet three conditions per WV Publication TSD-310: the work substantially adds to the value or useful life of the property; it becomes permanently affixed so that removal would cause material damage; and it’s intended as a permanent installation. Miss any one of those three, and the job is taxable.
Arizona
Arizona’s Transaction Privilege Tax (TPT) turns on the type of project. For prime contracting and modification projects (new construction and significant changes to real property) TPT applies to the contractor’s gross receipts, labor included, at a state rate of 5.6% plus local rates. For MRRA projects (maintenance, repair, replacement, or alteration below the modification threshold), labor is not taxable, only materials are. Misclassifying a project between “modification” and “MRRA” is one of the most reliable ways to trigger an Arizona audit.
States With Specific Exceptions
Texas
As described above, the residential/nonresidential line is everything in Texas. New construction and residential repair labor: not taxable. Nonresidential repair and remodeling: the Texas Comptroller taxes the total charge, labor and materials together, regardless of contract structure. A contractor can’t avoid tax on a commercial remodel by switching to a lump-sum contract; the whole bill is taxable either way.
New York
New York’s framework hinges on work type, not property type. Per NY DOR Tax Bulletin TB-ST-129, repair, maintenance, and installation work is taxable. The contractor collects sales tax on the full charge for materials and labor. Capital improvements are exempt: no tax on either labor or materials billed to the customer (though the contractor still pays tax on material purchases). The line between the two categories isn’t always obvious, and New York’s Publication 862 provides project-by-project guidance on how the state classifies specific types of work.
Connecticut
Labor on existing commercial, industrial, or income-producing real property is taxable at 6.35%. Labor on new construction and owner-occupied residential property is generally exempt. The same HVAC contractor, doing the same work, owes tax in the commercial office building and nothing in the house next door.
Washington
For custom prime construction (building a new structure), retail sales tax applies to total charges, labor included. Subcontractors working under a prime contractor on those projects are generally treated as making wholesale sales and don’t collect retail tax separately.
Minnesota
Minnesota is mostly exempt territory for construction labor, with one practical exception: installed items that retain their identity as tangible personal property: bleachers, lockers, certain machinery don’t become real property when attached. In those cases, both the item and the installation labor are taxable.
Contract Structure and Subcontractors
How a contract is written (lump-sum vs. time and materials) can shift who owes tax and when. In a lump-sum contract, the contractor pays tax on materials at purchase and doesn’t add a separate tax line on the customer’s invoice. In a time and materials contract, the contractor may purchase materials tax-free with a resale certificate and then collect sales tax from the customer on the materials portion. Labor typically stays exempt regardless of contract type (in states where it’s exempt at all).
Per Wolters Kluwer, states that apply resale treatment only under itemized contracts include Colorado, DC, Indiana, Mississippi, and Texas. States that apply it under both contract types include Arizona, Hawaii, Mississippi, Nebraska, and New Mexico.
For subcontractors, the general rule is that each contractor in the chain handles their own tax obligations independently. In most lump-sum states, subcontractors are consumers of their own materials and pay tax at purchase. In states that allow resale treatment under separated contracts like New York, a general contractor can issue a Form ST-120.1 Contractor Exempt Purchase Certificate to purchase a subcontractor’s taxable services for resale, with the GC ultimately collecting tax from the owner. Getting the subcontractor chain right matters because auditors look at it.
Working Across State Lines
For contractors taking jobs in multiple states, the compliance math compounds fast. Every job site can create sales tax nexus in that state, even short-term, triggering registration and filing obligations. If you’ve been running jobs across state lines without evaluating your exposure, a Voluntary Disclosure Agreement (VDA) is often the cleanest path forward. It limits lookback periods and typically eliminates penalties. Once a state contacts you first, that option disappears.

Frequently Asked Questions
Do contractors charge sales tax on labor in most states?
No. In most states, labor on real property construction is exempt. Contractors pay tax when purchasing materials and factor that into pricing. The labor line on the invoice is generally not taxed. If you’re unsure whether your state has an exception, HOST can help.
Which states tax construction labor?
Hawaii, New Mexico, and Arizona (for prime/modification projects) apply broad-based taxes to construction services. South Dakota has a 2% Contractor’s Excise Tax. West Virginia taxes labor unless the work qualifies as a capital improvement. Texas taxes labor on nonresidential repair and remodeling. New York taxes repair, maintenance, and installation labor. Connecticut taxes labor on existing commercial property.
Does the type of contract affect sales tax on labor?
Yes, and significantly in some states. Lump-sum contracts typically result in the contractor paying tax on materials at purchase with no customer-facing tax. Time and materials contracts can require collecting tax on the materials portion from the customer. See Wolters Kluwer’s breakdown for which states apply resale treatment to each contract type.
Does working in another state create a sales tax obligation?
Yes. A job site creates physical nexus, even temporarily, triggering registration and filing requirements. Multi-state contractors should run a nexus analysis before the first job is billed, not after.
What if a contractor hasn’t been collecting tax where required?
A Voluntary Disclosure Agreement (VDA) lets you come forward proactively, limits the lookback period, and typically eliminates penalties. Once a state initiates contact, that window closes. If a notice has already arrived, HOST’s audit defense team can step in.
