Tennessee Sales Tax for Contractors: Real Property vs Repair Rules (2026–2027)

Short answer: Under Tennessee sales tax for contractors rules (Tenn. Code Ann. § 67-6-209), a contractor who improves, alters, or constructs real property is treated as the end consumer of all materials used on the job. You pay the 7% Tennessee state sales tax plus local option tax (typically 9.25% to 9.75% combined) at the supply house and do not charge sales tax on your contract labor or lump-sum invoice to the property owner. By contrast, repairing or servicing tangible personal property requires collecting sales tax on the full charge.

Tennessee’s sales and use tax framework draws a bright statutory line between real property improvements and tangible personal property (TPP) repairs. Misclassifying an installation as a taxable repair—or buying lumber and pipe tax-free on a resale certificate when you intend to install them into a house—is one of the fastest ways to trigger an assessment during a Tennessee Department of Revenue (TDOR) audit. As contractors plan job costing and commercial bids across the 2026 and 2027 tax years, you also have to account for Tennessee’s Single Article Tax cap on expensive equipment and the state’s separate Business Tax gross-receipts filing thresholds.

How does Tennessee sales tax work for real property contractors in 2026–2027?

Tennessee treats real property contractors—roofers, framers, drywallers, plumbers installing rough-in piping, electricians wiring a structure, and concrete flatwork crews—as the users and consumers of every nail, board, shingle, wire reel, and fixture they fasten to land or a building. Under Tenn. Code Ann. § 67-6-209(b) and Tennessee Sales and Use Tax Rule 1320-05-01-.07:

1. You pay tax when you buy materials. When you purchase materials at a Tennessee supply house or lumberyard, you pay the 7.0% state sales tax plus the applicable county/city local option tax (ranging from 1.5% to 2.75%, bringing most jobsites in Nashville/Davidson, Memphis/Shelby, Knoxville/Knox, and Chattanooga/Hamilton between 9.25% and 9.75%).
2. You do not charge the customer sales tax on real property contracts. Whether you bill the homeowner or general contractor on a lump-sum, cost-plus, or time-and-materials basis for a real property improvement, the customer invoice shows $0.00 sales tax. Instead, your paid material tax is embedded in your material cost or overhead recovery.
3. Out-of-state material purchases require Tennessee Contractor’s Use Tax. If you buy cabinets, trusses, or HVAC units from an out-of-state vendor in Kentucky, Georgia, or Alabama that did not collect Tennessee tax, you must self-assess and remit Tennessee use tax based on the local rate of the Tennessee county where the jobsite is located.

When is repair or installation labor taxable in Tennessee?

Tennessee taxes “the installing of tangible personal property that remains tangible personal property after installation” and “the repairing of tangible personal property” under Tenn. Code Ann. § 67-6-102. The decisive test is whether the item becomes a permanent fixture of the real estate or stays movable personal property:

• Non-taxable real property labor: Replacing a roof, pouring a driveway, wiring a 200-amp breaker panel, replacing a central split-system heat pump, snaking a clogged main sewer line (when no tangible personal property is repaired), or remodeling a kitchen.
• Taxable tangible personal property labor: Repairing a freestanding refrigerator or commercial ice machine, servicing a portable generator, repairing a window air-conditioning unit, fixing detached shop machinery in a factory, or installing trade fixtures that a commercial tenant retains the right to remove at the end of a lease.

When you perform a taxable TPP repair, you purchase the replacement components tax-free using a Tennessee Blanket Certificate of Resale and collect the full state and local sales tax on both the parts and the repair labor on the customer’s invoice.

How does the Tennessee Single Article Tax cap affect contractors buying big equipment?

Tennessee has a unique rule called the Single Article Tax (Tenn. Code Ann. § 67-6-702) that directly lowers the tax burden when a contractor purchases a single piece of tangible personal property—such as a commercial rooftop HVAC package unit, a walk-in cooler, a backup generator, or a skid steer—costing more than $1,600:

1. Local option tax applies only to the first $1,600 of the price of a single article. At a 2.75% local rate, local tax caps out at $44.00 per single article ($1,600 multiplied by 2.75%).
2. An additional 2.75% state single-article tax applies only to the portion of the single item’s price between $1,600.01 and $3,200.00 (a maximum of $44.00 in supplemental state tax).
3. Above $3,200.00, only the standard 7.0% Tennessee state sales tax applies to the remainder of that single item’s purchase price.

For a contractor buying a $9,500 commercial condensing unit in a 9.75% county, failing to check that the supply house applied the single-article cap means overpaying $173.25 in local tax on a single invoice. Always verify that high-ticket equipment lines are billed as discrete single articles rather than bundled into a lump-sum kit.

What if a Tennessee contractor works for a tax-exempt church, school, or government agency?

Under Tenn. Code Ann. § 67-6-209(b), a contractor is ordinarily taxable on materials used in a real property contract even when the property owner is an exempt organization—unless the exempt entity directly purchases the materials itself on its own purchase order and pays the vendor with its own funds, or provides a valid statutory contractor exemption authorization where applicable (such as certain qualified industrial development or government projects). Never assume that a client’s 501(c)(3) letter lets you buy lumber or pipe tax-free at the supply house on your own account; verify the exact exemption certificate rules in the Tennessee Department of Revenue SUT-44 contractor guidance before bidding a tax-exempt job.

How does the Tennessee Business Tax ($100,000 threshold) interact with sales tax in 2026–2027?

Following the Tennessee Works Tax Act, Tennessee’s gross-receipts Business Tax filing threshold was raised to $100,000 per jurisdiction for tax years open in 2026 and 2027:

• If your gross receipts from work performed inside a given Tennessee county or incorporated municipality are under $100,000 for the year, you only need a Minimal Activity License ($15 annual fee with the county/city clerk) and do not file a Tennessee Business Tax return for that jurisdiction.
• Once your gross receipts reach $100,000 or more in a county or city, you must hold a Standard Business License and file an annual Business Tax return through TNTAP (Tennessee Taxpayer Access Point), where contractors typically fall under Classification 4.
• Subcontractor payments can only be deducted on your Classification 4 Business Tax return if you record each subcontractor’s business name, address, license number, and exact amount paid—which makes organized subcontractor ledger tracking essential alongside your 1099-NEC contractor reporting.

How should Tennessee contractors format estimates and invoices?

Because a real property contractor is the statutory taxpayer on materials, you should never display a separate “9.75% Sales Tax” line on a residential roof replacement, deck build, or bathroom remodel invoice unless you hold a dual-business registration and are making an explicit retail sale of unincorporated goods. If you collect “sales tax” on a real property lump-sum invoice by mistake, TDOR requires you to remit every dollar of that erroneously collected tax to the state while still owing use tax on your materials.

Instead, build the supply-house tax into your material unit cost before applying your markup, just as contractors do under Washington sales tax for contractors or Arizona sales tax for contractors when pricing tax-included cost layers.

Frequently asked questions

Do contractors charge sales tax on labor in Tennessee?

No, not on real property construction, remodeling, or structural installation contracts. Under Tenn. Code Ann. § 67-6-209, a real property contractor pays sales or use tax when purchasing materials and does not charge sales tax on labor or the contract total to the customer. Sales tax is only charged on labor when repairing or installing tangible personal property that remains movable personal property.

Can a Tennessee contractor use a resale certificate to buy building materials?

No. A contractor cannot use a Tennessee Certificate of Resale to purchase lumber, concrete, shingles, wiring, or plumbing materials that the contractor will install into real property. A resale certificate may only be used for items you resell at retail without installing into realty, or for parts used in taxable repairs of tangible personal property.

How does Tennessee’s $1,600 to $3,200 single article tax work on HVAC or heavy equipment?

When you buy a single unit of tangible personal property—such as an HVAC condenser, boiler, or trailer—local option sales tax (1.5% to 2.75%) applies only to the first $1,600 of that unit’s price, and an extra 2.75% state single-article tax applies only to the slice between $1,600.01 and $3,200. Above $3,200, only the 7% state rate applies.

Do I owe Tennessee use tax if I bring materials across the state line?

Yes. If you purchase materials in another state or online where Tennessee sales tax was not collected, or if the other state’s tax rate was lower than the combined Tennessee state and local rate where the jobsite is located, you must report and pay contractor’s use tax via TNTAP for the difference.

What is the 2026–2027 Tennessee Business Tax threshold for contractors?

Under the Tennessee Works Tax Act in effect for 2026 and 2027, contractors with less than $100,000 in annual gross receipts within a given county or city only need a $15 Minimal Activity License from the local clerk. Contractors with $100,000 or more in gross receipts in a jurisdiction must hold a Standard Business License and file an annual Classification 4 Business Tax return via TNTAP.
