Kansas Remodel Tax: What’s Taxable and What’s Exempt

Kansas sales tax on a remodel comes down to one split: materials are always taxable, and labor is exempt when the work is done on a residence but taxable when it’s done on a commercial property. The state rate is 6.5%, and local add-ons can push the combined rate above 11%, so where the project sits and how the invoice is written both matter.¹

Materials Are Always Taxable

Lumber, tile, paint, plumbing fixtures, wiring, cabinetry, shingles — every physical item that becomes part of a remodel is subject to Kansas sales tax at the full combined state and local rate. K.S.A. 79-3603 imposes the 6.5% state tax on retail sales of tangible personal property, and cities, counties, and special districts stack their own percentages on top.¹

Kansas treats the contractor, not the property owner, as the final consumer of those materials. Under K.S.A. 79-3603(l), materials sold to contractors for use in building on, improving, or repairing real property are taxable retail sales. Contractors pay the tax when they buy at the supply house, and they cannot use a resale exemption certificate to avoid it. That rule still applies when the project is for a tax-exempt entity like a church or a government building.²

In practice, the material cost on your invoice already includes sales tax your contractor paid upstream. If you buy the materials yourself and hire someone only to install them, you pay the sales tax at the register. Either way, tax on the physical goods gets collected before they reach your house.

Labor on Residential Remodeling Is Exempt

K.S.A. 79-3603(p) generally taxes the service of installing or applying tangible personal property, but it carves out a broad exception for residential work. Labor tied to the construction, remodeling, renovation, repair, or replacement of a residence is exempt from Kansas sales tax.¹ That covers the plumber roughing in new pipes, the electrician rewiring a kitchen, the framing crew opening a load-bearing wall. Your contractor should not add sales tax to the labor line on an invoice for residential work. If they do, the exempt amount is money you won’t get back unless you catch the error yourself.

What Counts as a Residence

Kansas reads “residence” broadly. It includes single-family homes, duplexes, townhouses, apartments, condominiums, nursing homes, dormitories, and rooming houses. Mobile and manufactured homes qualify when they’re connected to water, sewer, and electrical service on a fixed site. A vacation home or seasonal cabin counts as a secondary residence and keeps the exemption.²

The definition extends to land improvements that serve the dwelling: yards, garages, sidewalks, and driveways. Replacing a driveway or putting up a detached garage at your home falls under the residential umbrella.

Properties that don’t qualify include hotels, motels, inns, tourist courts, resort lodges, unattached mobile homes, RVs, and any accommodation routinely rented for 28 consecutive days or less.²

Residential Labor That’s Still Taxed

The exemption isn’t a blanket pass on every service performed at your home. Two categories of labor remain taxable even inside a residence. First, labor to install tangible personal property as part of its retail sale, such as an appliance crew hooking up a dishwasher or a window treatment company hanging custom draperies. Second, labor to repair tangible personal property that stays personal property rather than becoming part of the building itself, like fixing a freestanding washing machine or servicing a television.²

The line is whether the work attaches to the building or to a movable item inside it. Replacing built-in kitchen cabinets is exempt labor. Repairing a freestanding refrigerator is not. If a remodel invoice mixes appliance purchases with construction, make sure the exempt labor and the taxable labor sit on separate lines.

Commercial Remodeling Labor Is Fully Taxable

The residential exemption does not carry over to commercial property. Labor for repairing, maintaining, remodeling, or renovating offices, retail storefronts, warehouses, restaurants, and other commercial buildings is subject to the full combined state and local sales tax. Bids on commercial renovations need to account for sales tax on both materials and labor.²

One exception cuts across both categories: labor for the original construction of any new building or facility is exempt regardless of use. Tearing down an old structure and putting up something entirely new on the site is original construction, and the installation labor isn’t taxed. Adding an entire new room or floor to the exterior of an existing commercial building also qualifies, as long as the interior work is directly necessary to support that addition.³

Dual-Use Buildings

When a building serves both residential and commercial purposes, such as a ground-floor shop with apartments above, labor charges have to be split between the exempt residential portion and the taxable commercial portion. If the work can’t be assigned entirely to one use, Kansas requires the allocation to be based on the square footage of each area.²

Figuring the Combined Rate at Your Address

Kansas uses destination-based sourcing under K.S.A. 79-3670. The rate depends on where the materials are delivered or the labor is performed, not where the contractor’s office sits.⁴ For a remodel, that means your project address.

The 6.5% state rate is only the starting point. Counties, cities, and special taxing districts each add their own layers, and combined rates around Kansas run from 6.5% in areas with no local tax up to about 11.5% where multiple local levies stack. On a $30,000 materials bill, the spread between those extremes is roughly $1,500 in tax.

Local rates change quarterly, with new rates taking effect January 1, April 1, July 1, and October 1.⁵ The Kansas Department of Revenue publishes an address-based lookup that returns the exact combined rate for a project site.⁶ Check it before finalizing the budget, especially on projects that cross a quarter boundary.

Out-of-State Material Purchases

Ordering materials from an out-of-state supplier doesn’t get you out of the tax. Kansas imposes a compensating use tax at the same combined rate as the sales tax when you buy materials from outside the state and bring them in for a project. If the out-of-state retailer doesn’t collect Kansas tax at the sale, the buyer owes the use tax directly to the Kansas Department of Revenue.

A one-time purchase gets reported on a Consumers’ Use Tax Return (Form CT-10U). Contractors who regularly source from out of state register for a Consumers’ Use Tax reporting number using a Business Tax Application (CR-16) and remit on a periodic schedule. If you paid sales tax to another state on the same purchase, Kansas credits that amount, but only up to the Kansas rate. Any shortfall still has to be paid.

Penalties for Getting It Wrong

Underpaying or failing to remit Kansas sales tax triggers a penalty of 1% per month on the balance due, capped at 24% of the unpaid tax. When the shortfall is discovered in a field audit, the cap drops to 10%. Interest runs on top of the penalty from the original due date until the balance is paid.⁷

If an audit produces additional tax, the Department of Revenue sends a notice summarizing what’s owed. You have 30 days to respond or pay before the assessment becomes final, after which more interest and penalty can accrue.⁸ The biggest exposure for contractors is failing to collect sales tax on commercial labor and then being held personally liable for it. The most common miss for homeowners is paying tax on residential labor that should never have been on the invoice in the first place.
