Sales tax on labor in Oklahoma: not taxed on repairs to things, building repairs and new construction; installation depends on the job

Repairing a thing in Oklahoma

Not taxed. Oklahoma treats a repair person as the consumer of the parts used in the repair: you pay sales tax when you buy the parts, and the repair service itself is not on the list of taxable sales.

• “Repairmen are persons engaged in the business of repairing tangible personal property. Parts incidental to the repair service which are consumed/used in making repairs are taxable to the repairman as a consumer/user.” — OAC 710:65-1-7 Consumer/user defined; specific applications, (4) Repairmen, page date: 2022 compilation

Repairing a home or building in Oklahoma

Not taxed. Contractors who repair, alter, remodel or improve buildings are consumers: they pay sales tax on materials and supplies when buying them and do not charge sales tax on the job.

• “Contractors are defined by statute as consumer/users and must pay sales tax on all taxable services and tangible personal property, including materials, supplies, and equipment purchased to develop, repair, alter, remodel, and improve real property.” — Publication D: Oklahoma Sales Tax Vendor Responsibilities / Exempt Sales (Oklahoma Tax Commission), quoting OAC 710:65-7-13, page date: Revised November 2026

Installation work in Oklahoma

It depends. If you sell an item and install it, the installation charge is not taxed only if you show it separately (at your standard retail price for the item). What it turns on: whether the installation charge is separately stated on the invoice; and whether the job is a real-property improvement (contractor = consumer) or a sale of an item with installation.

• “he may make a separate and additional charge for making the installation which, when shown separately in his billings and on his books, will not be subject to the sales tax.” — OAC 710:65-19-159 Installation charges, page date: 2022 compilation

New construction in Oklahoma

Not taxed. Contractors are consumers of the materials, supplies and equipment used to develop and improve real property and pay sales tax when buying them.

• “Contractors are defined by statute as consumer/users and must pay sales tax on all taxable services and tangible personal property, including materials, supplies, and equipment purchased to develop, repair, alter, remodel, and improve real property.” — Publication D: Oklahoma Sales Tax Vendor Responsibilities / Exempt Sales (Oklahoma Tax Commission), quoting OAC 710:65-7-13, page date: Revised November 2026

Listing labor separately on the bill in Oklahoma

Changes the answer. When you sell an item and install it, a separately shown installation charge is not taxed; a lump sum is taxed in full.

• “he may make a separate and additional charge for making the installation which, when shown separately in his billings and on his books, will not be subject to the sales tax.” — OAC 710:65-19-159 Installation charges, page date: 2022 compilation
• “(a) Where the quoted or advertised price is a lump sum for both property and installation or where billing and other records do not show separate charges for property and for installation, the measure of the tax is the total gross receipts received by the seller. (b) ... he may make a separate and additional charge for making the installation which, when shown separately in his billings and on his books, will not be subject to the sales tax.” — OAC 710:65-1-7 Consumer/user defined; specific applications, (4) Repairmen, page date: 2022 compilation
