Do Contractors Charge Sales Tax on Labor in NY? Yes, Unless
Short answer: Do contractors charge sales tax on labor in NY? Yes, on repair, maintenance and installation work: New York taxes the whole bill, labor and materials together. No, on a capital improvement, as long as the customer gives you a completed Form ST-124.
So the real question is never “is labor taxable.” It’s “what kind of job was this.” Separating labor from materials on the invoice does not change the answer, and you pay tax on your own materials either way.
It’s a Thursday in late October and Teodoro — I’ll call him Teodoro — is sitting in his pickup outside a lumberyard in Rochester. He runs a three-person carpentry and handyman outfit. On the passenger seat: a coffee, a tape measure, and a stack of invoices he is about to send. In the glovebox: eleven Form ST-124s, two takeout menus, and a tire gauge that has never measured a tire.
This week he built a deck, replaced a rotted stair tread, hung a set of new kitchen cabinets, and repainted the old ones in a customer’s basement. Four jobs. He charged sales tax on exactly one of them, and he picked which one by feel.
Teodoro isn’t careless. He’s running a business under a tax rule that sorts jobs by outcome, not by effort — and nobody ever handed him the sorting key. Here it is.
The one question that decides it: repair or improvement
New York doesn’t sort your work into “labor” and “materials” and tax one of them. It treats the whole job as a single service to real property, then asks what the property looks like when you drive away. That’s why the state’s bulletin on repair, maintenance and installation services says the taxable amount is all the charges for materials and labor you bill, markups included.
Think of it as a haircut versus a tattoo. A haircut maintains what was already there and grows back; the state taxes it. A tattoo is a permanent change to the property; the state doesn’t. Nobody has ever argued their haircut was a capital improvement, though several people have tried with their bathroom.
- Repair or maintenance: taxed. Fixing a broken railing, re-pointing a chimney, replacing a faucet, replacing damaged shingles. The thing existed; you kept it working.
- Installation of things that stay movable: taxed. Hooking up a freestanding appliance, putting up an above-ground pool or a canvas awning. The item never becomes part of the building.
- Capital improvement: not taxed. Building a deck, installing a hot water heater, putting in kitchen cabinets. The property is permanently better, bigger, or longer-lived than before.
The regulations judge the end result, not the steps. A job full of capital-looking tasks that ends in a repaired wall is a repair.
The three tests for a capital improvement
Under Tax Bulletin ST-104 on capital improvements, a job only escapes sales tax if it passes all three of these. Two out of three is a repair with good intentions.
- 1. It substantially adds value or appreciably prolongs the property’s useful life. A new roof does. Patching three shingles keeps the existing roof going, which is the definition of maintenance.
- 2. It becomes part of the property or is permanently affixed to it. Built-in cabinets, yes. A freestanding fridge, no, however expensive it was and however long it took to get through the door.
- 3. It is intended to be a permanent installation. This is the test that trips up commercial work. Items a commercial tenant installs as trade fixtures may not qualify even when the identical item would qualify for an owner.
The third test is the one where the state asks what everybody was thinking when the work was done — a question most of us would rather not answer about our own kitchens.
Common jobs, sorted: taxed or not
The state publishes a long list of examples in Publication 862. These are the ones that come up most for small contractors. The pattern: complete and new is an improvement, partial and existing is a repair.
- Roofs. Replacing the entire roof, or the complete side of a peaked roof, is a capital improvement. Repairs, spot replacement, coatings and gutter cleaning are taxed.
- Painting. Painting a new structure is part of the improvement. Repainting existing walls, doors or cabinets is taxed — which is how Teodoro’s basement cabinet job ended up taxable while the new cabinets upstairs did not.
- Floor coverings. Carpet or vinyl as the first finished floor in new construction or a new addition is an improvement. The same carpet in an existing building is a taxable installation.
- Driveways and walks. Installing or completely repaving is an improvement. Patching holes and cracks, or replacing sections, is taxed.
- Masonry. Installing or completely replacing a wall, footing or sidewalk is an improvement. Repairing or partly replacing one is taxed.
- Yard work. Planting trees and shrubs or putting in a permanent fence is an improvement. Mowing, pruning, fixing a fence and snow removal are taxed.
Our favorite oddity: carpet in a brand-new building is an improvement, but the same carpet installed more than six months after the building was finished is taxable. The carpet has no idea what day it is. The tax code does.
Form ST-124: the paper that does the arguing for you
On a capital improvement job, the customer fills out Form ST-124, Certificate of Capital Improvement, and both of you sign it. That one page changes who has to prove what if the state ever asks.
- Get it within 90 days. If you receive a properly completed ST-124 within 90 days of doing the work and accept it in good faith, the customer carries the burden of proving the job wasn’t taxable. Miss the window and that burden sits with you.
- Good faith has limits. It means you didn’t know the certificate was false and used ordinary care accepting it. A signed ST-124 for a cracked-window repair is not a document you can lean on.
- You don’t have to accept it. If you think the job is a repair, you can refuse the form and charge tax. Signing an improper certificate can make you personally liable for the tax, plus penalties and interest.
- Keep it three years, and share it. Keep each certificate for at least three years after the related return was due or filed, whichever is later, and give copies to every subcontractor on the job.
A glovebox is technically a filing system. It is just one with no index, no backup, and a tire gauge in it.
Here is the honest part: if nearly all your work is new decks, additions and full remodels for homeowners, and you collect a signed ST-124 at the start of every job, you probably don’t need an accountant for this. You need a folder and the habit. Buy the folder.
You still pay tax on materials either way
This is the part that surprises people who came from retail. In New York, contractors are generally the consumer of the building materials they buy, so you pay sales tax at the lumberyard. ST-104 is blunt about it: there is no exemption for materials used in a capital improvement project.
- On a capital improvement, the tax you paid on materials is a cost of the job. No credit, no refund. Price it in.
- On a taxable repair, you collect tax on the whole bill, including the materials, and you may be able to take a credit for the tax you already paid on materials you transferred to the customer, claimed on your sales tax return.
- You can’t use ST-124 to buy tax-free. The certificate covers what you charge the customer, not what the supplier charges you.
The lumberyard does not ask whether your two-by-fours are headed for a new deck or a patched one. It charges tax and wishes you a good weekend.
How to bill a taxable job
The state’s own example in TB-ST-129 is a homeowner repair with $130 of materials and $250 of labor. The tax applies to the full $380, not just the $130. At the illustrative 8% rate the bulletin uses, that is $30.40 of tax and a $410.40 total. Your actual rate is the combined state and local rate where the work is done.
- 1. Decide the job type before you quote. Repair or improvement changes the price the customer pays, so settle it at the estimate, not at the invoice.
- 2. Tax the whole bill on a repair. Labor, materials, trip charges and markups. Itemizing labor is fine for clarity, but it doesn’t take labor out of the taxable amount.
- 3. Collect the ST-124 on an improvement. At signing is best. Within 90 days is the deadline that matters.
- 4. Split mixed jobs in writing. A remodel plus an unrelated repair is two jobs. Write them up as two, so one doesn’t drag the other’s tax treatment with it.
Writing “LABOR” in bigger letters does not help. We’ve seen it tried. The font size has no standing.
Once you’re collecting tax, the returns follow New York’s odd calendar — we covered when NYS sales tax is due yesterday. If you also work across state lines, compare how Florida taxes labor, and the bigger picture in our guide to sales tax compliance for small businesses. Full disclosure: we are an accounting firm, and our idea of a capital improvement is a second monitor.
What a wrong guess costs three years later
Picking repair-or-improvement by feel works fine right up until an auditor sorts the same jobs by the rules. The tax you didn’t collect doesn’t disappear. It just stops being your customer’s money and becomes yours.
Do the arithmetic with illustrative numbers. Say $100,000 a year of your work is repairs you treated as improvements, at an 8% combined rate. That is $8,000 a year you never collected. Across three years of records, $24,000 — before penalties and interest, and with no way to send the customers a bill for tax they were never charged.
The other mistake costs too, just more quietly: charging tax on genuine improvements makes your quotes 8% higher than the contractor down the road who knows the rule. Either way, the sorting key is cheaper than the guess.
Frequently asked questions
- Do contractors charge sales tax on labor in NY?
- Yes, when the job is a repair, maintenance or installation service to real property: New York taxes the whole charge, labor and materials included. No, when the job is a capital improvement and the customer gives the contractor a properly completed Form ST-124, Certificate of Capital Improvement.
- Is labor taxable in New York State?
- It depends on what the labor accomplishes. Labor to repair, maintain or install items that do not become part of a building is taxable. Labor that results in a capital improvement, meaning it adds substantial value or prolongs useful life, becomes part of the property, and is intended to be permanent, is not taxable.
- What counts as a capital improvement for NY sales tax?
- A capital improvement is an addition or alteration to real property that meets all three conditions: it substantially adds to the value or appreciably prolongs the useful life of the property, it becomes part of or is permanently affixed to the property, and it is intended to be a permanent installation. Building a deck, installing kitchen cabinets and replacing an entire roof are examples.
- Who fills out Form ST-124?
- The customer completes Form ST-124 and gives it to the contractor, and both sign it. The contractor keeps it, gives copies to any subcontractors on the job, and must keep it for at least three years. If the contractor gets it within 90 days of doing the work and accepts it in good faith, the burden of proving the job was taxable shifts to the customer.
- Do contractors pay sales tax on materials in New York?
- Yes. Contractors pay sales tax when they buy building materials, whether the materials go into a capital improvement or a repair, and there is no exemption for materials used in a capital improvement. On a taxable repair job, the contractor may be able to take a credit for the tax already paid on materials that were transferred to the customer.
- Is roof repair taxable in NY?
- Yes. Repairing or spot-replacing roofing materials, and cleaning or repairing gutters, is taxable repair work. Replacing an entire roof, or the complete side of a peaked roof, is a capital improvement and is not taxed when the customer provides Form ST-124.
- Is carpet installation taxable in New York?
- Usually, yes. Installing carpet or similar floor covering in an existing building is a taxable installation service. It is a capital improvement only when it is the initial finished floor covering in new construction or a new addition, or is installed within six months after the building is otherwise completed.
- Is painting taxable in NY?
- Painting existing walls, doors, cabinets or structures is taxable repair and maintenance work in New York. Painting a new structure, or painting, staining or sealing a new deck, door or set of cabinets, is classified as a capital improvement.
