# Do Contractors Charge Sales Tax on Labor or Materials?

It depends on the state and the job. In many states a contractor improving real property is the consumer of the materials: it pays tax when buying them and charges no tax on labor. Other states tax repair or installation labor, and a few tax the whole contract price. Contract type and improvement-vs-repair status can change the answer.

## Key takeaways

- There's no national rule. Sales tax is set state by state, and local rates and rules layer on top.
- Model 1: the contractor is the consumer of materials, pays tax on purchases and charges the customer no tax (common for real property improvements).
- Model 2: the contractor is a retailer of materials or fixtures, buys for resale and charges tax on them, usually not on labor.
- Model 3: labor itself is taxable for some work, such as repairs, maintenance or nonresidential remodeling in certain states, or the whole contract price in a state like Washington.
- How you write the contract (lump sum vs. separately stated materials) can change who pays the tax.

## Why sales tax on contracting work is confusing

Sales tax was built for selling goods across a counter. Contractors take goods (lumber, wire, pipe, shingles) and turn them into part of a building, which in tax terms usually stops being "tangible personal property" and becomes **real property**. Each state decides who pays tax in that handoff, and whether the labor that does it is taxable. Three questions decide most cases:

1. **Is the work an improvement to real property, or a repair, maintenance or installation service?** Several states draw this line, and it often decides whether labor is taxed.
2. **Is the item a material or a fixture?** Materials lose their identity (drywall, concrete). Fixtures keep it (a furnace, a water heater, a ceiling fan). Some states treat them differently.
3. **How is the contract written?** A lump-sum price, a time-and-materials bill, or a contract that sells materials separately from installation can each be taxed differently.

## The three main models states use

**How states tax contractors: the main models**

| Model | Who pays tax on materials | Is labor taxed? | Example states |
| --- | --- | --- | --- |
| Contractor is the consumer of materials | Contractor, when buying from the supplier | Usually no; customer isn't charged sales tax | California (materials), Florida (lump-sum and most real property contracts), New York (capital improvements) |
| Contractor is a retailer of materials or fixtures | Customer, on the contractor's invoice; contractor buys for resale | Usually no, if separately stated | California (fixtures), Texas (separated residential contracts), Florida (retail sale plus installation) |
| Labor or the full contract price is taxable | Varies; often bought for resale and taxed on the invoice | Yes, for the covered work | Washington (most construction), New York (repair, maintenance, installation), Texas (nonresidential repair and remodeling) |

## How five states handle labor and materials

### California: contractors consume materials and sell fixtures

The California Department of Tax and Fee Administration (CDTFA) says "construction contractors are generally the consumers of the materials they use" and owe tax on what they pay for them. It also says contractors "are the retailers of fixtures that they provide and install," so tax applies to the selling price of fixtures. Installation labor is generally not taxed; under a cost-plus contract, a separately stated fee is treated as nontaxable installation labor. Most contractors need a seller's permit, with exceptions for those who only furnish and install under lump-sum contracts. See the [California tax guide](https://www.brix.so/taxes/california).

### Texas: residential vs. nonresidential decides it

The Texas Comptroller's real property repair and remodeling guidance says "labor to repair, remodel, or restore residential real property is not taxable." Under a **lump-sum** contract, the contractor pays tax on materials when buying them and doesn't charge the customer tax. Under a **separated** contract, the contractor buys materials with a resale certificate and charges tax on the materials, not the labor. **Nonresidential** repair and remodeling is different: the contractor collects tax on the total charge, labor included. New construction labor is not taxable, and scheduled, periodic maintenance of real property isn't either (parts and materials still are). See the [Texas tax guide](https://www.brix.so/taxes/texas).

### New York: capital improvement vs. repair

New York taxes the **result** of the work. A capital improvement must meet three tests: it substantially adds value or prolongs the property's life, it becomes part of or is permanently affixed to the real property, and it's intended to be permanent. For a capital improvement, "there is no sales tax due on the charge to the customer," and the contractor pays tax on the building materials it buys. Repair, maintenance and installation services are taxable to the customer. Contractors should get a completed Form ST-124, Certificate of Capital Improvement, from the customer on capital improvement jobs. See the [New York tax guide](https://www.brix.so/taxes/new-york).

### Washington: tax on the whole contract price

Washington's Department of Revenue says prime contractors "must collect retail sales tax from the landowner on the gross contract price," with no deduction for costs. That means labor, materials and subcontracted work are all in the taxable amount. Contractors buy materials that become part of the project with a reseller permit, so they aren't taxed twice, but pay sales or use tax on tools, equipment and supplies they consume. Public road and federal government contracts follow different rules. See the [Washington tax guide](https://www.brix.so/taxes/washington).

### Florida: contractor as final consumer, unless it's a retail sale plus installation

The Florida Department of Revenue says that under lump sum, cost plus, fixed fee, time-and-materials and similar real property contracts, the contractor is the final consumer of materials and supplies: it pays tax to suppliers and should not charge tax to the customer. A **retail sale plus installation** contract works differently: the contractor lists and prices all materials before work begins, sells them as a separate transaction, and charges sales tax. See the [Florida tax guide](https://www.brix.so/taxes/florida).

## How the same job is taxed in different states

> **Example: a $12,000 job with $5,000 of materials and $7,000 of labor (illustrative)**
>
> **California, lump-sum remodel using materials:** the contractor pays tax on the $5,000 of materials when buying them and builds that cost into the price. The customer isn't charged sales tax on the labor.
>
> **Texas, residential remodel on a separated contract:** the contractor buys materials with a resale certificate and charges the customer tax on the $5,000 of materials. The $7,000 of labor isn't taxed. The same remodel on an office building is taxed on the full $12,000.
>
> **New York, new kitchen that qualifies as a capital improvement:** the customer pays no sales tax if the contractor has a completed ST-124; the contractor paid tax on the materials. A repair to an existing kitchen would be taxable to the customer.
>
> **Washington, any of the above:** the contractor collects retail sales tax on the full $12,000.
>
> **Florida, lump-sum contract:** the contractor pays tax on the $5,000 of materials and charges no tax to the customer.
>

## Sales tax on labor by trade

**Where trades run into labor and materials questions**

| Trade | Typical tax question |
| --- | --- |
| HVAC | Is the new system a fixture sold and installed, or part of a real property improvement? Is a service call a taxable repair? |
| Plumbing | Repair calls vs. repiping or a new bathroom; water heaters as fixtures |
| Roofing | Full replacement (often an improvement) vs. patching a leak (often a repair) |
| Electrical | Panel upgrades and rewiring vs. replacing a switch or fixture |
| Landscaping | Planting and hardscape (often an improvement in some states) vs. mowing and maintenance services |
| Cleaning | Some states tax cleaning or janitorial services outright; check yours |

_Patterns only. The answer depends on your state's rules and the facts of the job._

## Sales tax vs. use tax

Sales tax is collected by a seller. Use tax is the matching tax you owe directly when you use taxable items in the state without paying sales tax on them, for example materials bought from an out-of-state supplier that didn't charge tax, or items bought for resale that you then used on a job. Contractors run into use tax constantly; see [use tax for contractors](https://www.brix.so/learn/use-tax-for-contractors).

## Common mistakes

- **Assuming labor is never taxable.** In Washington, and for some work in New York and Texas, it is.
- **Charging tax on a lump-sum improvement job** in a state where the contractor is the consumer. You may be over-collecting from the customer and still owe tax on your purchases.
- **Buying everything with a resale certificate.** If you're the consumer of the materials, you owe tax (often use tax) on them.
- **Not writing contracts deliberately.** Lump-sum vs. separated pricing can change the tax; decide it on purpose, with your CPA.
- **Ignoring local rates and job location.** Rates often follow the job site, not your shop address.

> **When to get a CPA or the state involved**
>
> Ask a CPA or enrolled agent who knows your state's sales tax before you set up contract templates, start work in a new state, or take on commercial work. Many state revenue departments also answer written questions; their written guidance carries more weight than a phone call.

## Frequently asked questions

### Do contractors charge sales tax on labor?

Often not, but it depends on the state and the job. Many states don't tax labor for real property improvements. Some tax repair, maintenance or installation labor, like New York, or nonresidential remodeling, like Texas. Washington taxes the full contract price for most construction.

### Do contractors pay sales tax on materials?

In many states, yes. When the contractor is treated as the consumer of materials, as in California, Florida for lump-sum real property contracts, and New York for capital improvements, it pays tax when buying them and doesn't charge the customer sales tax on the job.

### Should I separate labor and materials on my invoice?

It can change the tax. In Texas, a separated residential contract lets you buy materials for resale and charge tax only on materials, while a lump-sum contract means you pay tax on purchases and charge none. In Florida, only a qualifying retail sale plus installation contract makes you a seller of the materials.

### What is the difference between a capital improvement and a repair?

In New York, a capital improvement substantially adds value or extends the property's life, becomes part of the real property and is intended to be permanent. Charges for it aren't taxed to the customer. Repairs and maintenance keep property in working order and are taxable.

### Is installation labor taxable?

It varies. California generally doesn't tax installation labor. New York taxes installation services when the item doesn't become part of the real property. Washington includes labor in the taxable contract price. Check your state's revenue department guidance.

### Where can I find my state's contractor sales tax rules?

Start with your state revenue department's contractor or construction guide, which most states publish. Our state guides at brix.so/taxes summarize each state and link to the official pages.
