Iowa Contractors Guide

Contractor

Anyone who provides labor and materials to build a structure is considered a construction contractor for that job, even if his or her usual occupation or profession is something else, such as a handyman.

Contractor includes a general contractor, subcontractor, or builder. The contractor can be an individual, corporation, partnership, or other entity.

Sponsor

A sponsor is the second party of the contract.

Construction Contract

A construction contract is an agreement between a contractor and a sponsor to provide labor and materials to build a structure.

A construction contract always involves changing tangible, personal, or “movable” property into real estate; for example, a change of concrete block and mortar into a foundation.

Types of Contracts

Types of contracts include, but are not limited to, lump sum contracts, cost plus contracts, time and material contracts, unit price contracts, guaranteed maximum or upset price contracts, construction management contracts, design build contracts, and turnkey contracts.

For a list of activities and items that could fall within the meaning of a construction contract or are generally associated with a construction contract, see Appendix C.

Building Materials, Supplies and Equipment

See Appendix B.

Types of Construction Contractors in Iowa

How a person is classified is the basis for determining many tax obligations. It can be difficult for a person starting a business to determine if that business will be engaged in contracting, retailing, a combination of the two, or providing repair services. However, one status must be chosen from the following:

Contractor
Contractor-retailer
Repair company
Manufacturer-contractor

Changing Status

A status should not be changed unless it becomes clear that the business has become another status.

Example
A business begins as a contracting business only. The owner begins to sell construction materials at retail and eventually the majority of the business' income is from these sales. The status changes from contractor to contractor-retailer.

Construction Contractor

Consumer of building materials and supplies purchased for use in construction contracts
Responsible for paying sales tax at the time the purchases are made or directly to the Department

Materials delivered in Iowa for use in a construction contract are subject to tax. It does not matter if the
materials purchased by a contractor are for use in construction contracts performed in Iowa or outside of Iowa.

Exemption Certificates

Contractors are not allowed to make purchases for resale just because they have a sales and use tax permit number. Jobs for most nonprofit organizations, including churches, are not exempt. Suppliers should not accept sales tax exemption certificates from contractors, unless a designated exempt entity exemption certificate and authorization letter are provided to a contractor by a designated exempt entity.

See Contracts with Designated Exempt Entities.

Contractor Tax Responsibilities by Situation

A contractor performs new construction.
The contractor must pay tax on materials at the time they are purchased and does not collect any tax from the customer.

A contractor performs a taxable service.
The contractor must pay tax on the materials at the time they are purchased. The contractor collects tax on both the labor and the materials from the customer. Since tax was already paid on the materials when the contractor purchased them, an adjustment can be made on the sales and use tax return by entering the amount the contractor paid for the materials as an “other” exemption on the sales tax portion of the return.

A person who is not in the construction business is building his or her own house.
The person must pay sales tax on the purchase price of the materials, supplies, and equipment. Owners are considered final consumers in the same way as contractors.

Contractor-Retailer

A contractor-retailer is a business, generally with a store front, that makes frequent retail sales of supplies and materials to the public or other contractors and builds residential or commercial structures.

A contractor-retailer must obtain a sales and use tax permit to report sales tax from retail sales and taxable repairs and to pay tax on materials withdrawn from inventory for use in a construction contract.

A contractor who rarely makes sales to individuals or other contractors is not considered a contractor-retailer
and must pay sales tax to suppliers or use tax to the Department on all purchases.

A contractor-retailer:

Purchases tax free building materials, supplies and ;equipment placed in its inventory for resale
Provides the supplier with a valid sales tax exemption certificate
Collects sales tax on the selling price when materials, supplies, and equipment are sold without installation
Pays tax to the Department if inventory is removed for use by the business
Pays tax to the supplier on materials not typically placed in inventory, such as wet concrete
Performing a construction contract - does not collect sales tax from the final customer
Performing a taxable service (repairs) - charges customers sales tax on labor and materials
Does not pay tax on materials withdrawn from inventory for use in construction projects performed outside Iowa

Contractor and Contractor-Retailer Examples

Example 1
ABC Company operates a retail outlet that sells lumber and other building materials and supplies. ABC is also a contractor that builds residential and commercial structures. Since ABC is a contractor-retailer, it purchases all inventory items for resale. When using materials to fulfill a construction contract, however, ABC will need to pay tax on their cost of the materials. This should be reported as “goods consumed” on the sales and use tax return. Items that are sold by ABC are subject to sales tax at the over-the-counter selling price.
Example 2
EFG Company is a mechanical contractor and has no retail outlets. EFG rarely sells any of its inventory to other persons or contractors; therefore, EFG is not considered to be a contractor-retailer. Since EFG is considered to be a contractor only, it must pay sales tax to its suppliers when it purchases building supplies and materials. On those rare occasions that EFG sells an item to another person or contractor, EFG must collect sales tax on the selling price. EFG must have a sales and use tax permit to report this tax. Since tax was already paid on the item when EFG purchased it, an adjustment can be made on the sales and use tax return by entering the amount EFG paid for the item as an “other” exemption on the sales tax portion of the return.
Example 3
Home Town Construction Company is owned and operated by two individuals in a rural Iowa farming community. They do not have a retail outlet but they frequently make sales of building materials from their inventory to local residents. Home Town Construction Company is a contractor-retailer because of the frequency of the sales and should purchase all inventory for resale. Items that are used in construction contracts are subject to tax on Home Town’s buying price at the time they are withdrawn from inventory. Items that are sold are subject to tax on the selling price.
Example 4
Down Home Construction Company is operated by two individuals in a rural Iowa farming community. They do not have a retail outlet and rarely sell building materials from their inventory. Because its sales are rare, Down Home is considered a contractor only and must pay sales tax to its suppliers when making purchases. However, since Down Home makes occasional sales, it must have a sales tax permit to collect and remit the tax on those retail sales.
Example 5
Intown Home Construction Company places modular homes on slabs or basement foundations, makes electrical, plumbing, and other connections, and otherwise prepares the modular homes for sale as real estate. Intown also has a sales and use tax permit, maintains an inventory of modular homes for sale, and sells homes from the inventory as tangible personal property to owners who later convert the property to real estate. Intown is a contractor-retailer and is obligated to pay tax when a modular home is withdrawn from inventory for use as material in a construction contract. It must collect the sales tax when the home is sold directly to an owner.
Example 6
Smith’s Plumbing has a retail store in Davenport, but they also install plumbing fixtures and lines in new construction and remodeling projects. As a contractor-retailer, plumbing supplies that are taken from their inventory for a new home being built in Rock Island, Illinois, are exempt from sales tax because the construction contract is outside of Iowa. However, those supplies may be subject to Illinois use or sales tax.

Repair Company

To determine if your business is strictly repair, see Job Classifications

If materials and labor are itemized separately on the bill to the customer, businesses that perform only repair jobs:

Do not pay sales tax on purchases of building materials and supplies purchased for resale
Make their purchases for resale
Give their supplier a valid Sales Tax Exemption Certificate (31-014)

If the repair company does not itemize materials and labor on billings, it will:

Pay tax on the materials purchased
Collect tax on the total bill

Manufacturer-Contractor

Sales by Manufacturers

Manufacturers who sell to contractors or other consumers are required to collect tax on the sales price.
Manufacturers who make retail sales are required to hold an Iowa sales and use tax permit.
Manufacturers of building materials, supplies, and equipment may sell their products and also use their products in construction contracts.

Applying Tax

If primarily a manufacturer
Tax is computed on “fabricated” costs. Fabricated costs include both direct and indirect expenses. This includes the cost of all materials, labor, power, transportation to the plant, and other plant expenses such as overhead, but it does not include installation on the job site.

If primarily a contractor
Tax is computed on the cost of raw materials.

New Construction

A manufacturer performing new construction does not collect sales tax from the final customer.

Taxable Repair Service

A manufacturer performing a taxable repair service may withdraw materials from inventory tax free. Tax is collected from the final customer on the labor and materials.

Out-of-State Projects

When tangible personal property is used by a manufacturer in construction contracts outside of Iowa, no Iowa sales or use tax is due.

Repair

“Repair” means mend, restore, maintain, replace, or service. A repair restores an existing structure that has been damaged.

When in doubt, a construction contract should be treated as being a taxable repair. If it is later determined that reconstruction rather than repair occurred, the sponsor may apply to the Department for a refund of tax paid.

Examples of taxable repair situations include:

Replacement, repair, or restoration of:
- Broken or defective glass / windows
- Individual or damaged roof shingles
- Defective garage door or garage door opener
- Defective kitchen cabinet
- Defective tub, shower, or faucet
- Defective water heater, furnace, or central air conditioning compressor
- Original wiring in a house or building

New Construction, Reconstruction, Alteration, Expansion, & Remodeling

If it is, the labor is exempt from sales tax. This exemption applies to real property and structures only. It does not apply to tangible personal property.

The contractor is responsible for paying tax to the supplier on materials.; The contractor does not charge tax to the customer on the labor or materials.

Examples of new construction, reconstruction, alteration, expansion, and remodeling activities.

Building a garage or adding a garage to an existing building (new construction)
Adding a redwood deck to an existing structure (new construction)
Replacing a complete roof on an existing structure (reconstruction)
Adding a new room to an existing building (new construction)
Adding a new room by building interior walls (alteration)
Replacing kitchen cabinets that are not defective (alteration or remodeling)
Paneling existing walls (alteration or remodeling)
Laying a new floor over an existing floor (alteration or remodeling)
Rebuilding a structure damaged by flood, fire, or other uncontrollable disaster or casualty (reconstruction)
Building a new wing to an existing building (expansion)
Rearranging the interior structure of a building (remodeling)
Installing a modular or mobile home on a foundation (new construction)
Replacing an entire water heater, water softener, furnace, or central air conditioning unit that is not defective (reconstruction or remodeling)
Sign installation and well-drilling services when performed in connection with new construction

Circumstances to Determine Whether a Project is Repair or Construction

Is the service performed closely with a construction activity?
For example, the service of excavating and grading of land to clear it for construction of a building is exempt because it is done in conjunction with new construction. However, excavating and grading land without the intent of construction is taxable.
Is the service performed at about the same time as the construction activity?
For example, if land is graded to seed a new lawn following construction, the service is exempt from tax. If, however, the lawn does not grow and the land is regraded the following year, the service is taxable because it is not performed in conjunction with new construction.
The physical relationship is considered.
If a building is constructed for machinery, installation of the machinery is exempt. For example, piping services that join two pieces of equipment in separate buildings are exempt if the equipment in either building is installed while new construction, reconstruction, alteration, expansion, or remodeling to the structure is also taking place.
Will the magnitude of the service make it exempt?
The “size” of a job should be considered when deciding if the job is a repair or new construction. For example, replacing damaged or missing shingles on a roof is repair and taxable; recovering an entire roof is construction and exempt.
Is the item being replaced defective?
For example, if a building’s existing furnace is not defective, but the owner of the building has a new, more energy efficient furnace installed, the service is reconstruction or remodeling. However, if the building’s furnace is defective, the replacement of the furnace is a repair.
Is the project a capital improvement?
A contract that qualifies as a capital improvement is not automatically treated as construction. The totality of the project must be considered in making that determination.

Both Construction and Repair

If this happens, the contractor must itemize the bill and charge sales tax on repair labor.

Example
A homeowner hires a contractor to add a new room to the existing home. This service is exempt as new construction. However, the home also needs restoration of its original wiring and replacement of a broken window. These are repairs and the labor and materials are taxable.

Designated exempt entities include only the following:

Private nonprofit educational institution in Iowa
Nonprofit private museum in Iowa
Tax-certifying or tax-levying body or governmental subdivision of Iowa, including the state board of regents, state department of human Services, state department of transportation, and recreational lake and water quality districts
Municipally-owned solid waste facility which sells all or part of its processed waste as fuel to a municipally-owned public utility
All divisions, boards, commissions, agencies, or instrumentalities of state, federal, tribal, county, or municipal government which do not have earnings going to the benefit of an equity investor or stockholder
A nonprofit Iowa affiliate of a nonprofit international organization whose primary activity is the promotion of the construction, remodeling, or rehabilitation of one-family or two-family dwellings for low-income families, such as Habitat for Humanity
Rural water districts organized under Iowa Code chapter 357A
An entity that is an instrumentality of a county or municipal government, including an agent of the entity, if the instrumentality or agent was created for the purpose of owning real property located within a reinvestment district established under Iowa Code Chapter 15J. Such entities are entitled to a sales tax exemption on building materials, supplies, or equipment that are completely consumed in the performance of a construction contract to construct a project, which project has been approved by the economic development authority board in accordance with Chapter 15J.
A county or district fair organized under Iowa Code Chapter 174.

NOTE:

Nonprofit hospitals are NOT designated exempt entities for this purpose.
A “tribal government” means the governing body of a federally recognized Indian tribe, as defined in Iowa Code section 216A.161.

Designated exempt entities may issue exemption certificates to contractors and subcontractors, allowing them to purchase or withdraw from inventory building materials for the contract free from sales tax.

This special exemption certificate also allows a manufacturer of building materials to consume materials in the performance of a construction contract with a designated exempt entity without owing tax on the fabricated cost of those materials.

See Index to Information About Construction Contracts with Designated Exempt Entities.

Manufactured Homes

Taxable:

5% use tax on 20% of the installed purchase price
Use tax paid to the manufactured home retailer at the time of sale
Purchaser must provide the retailer with all the information necessary to submit an application for title
The retailer is required to remit the use tax to the county treasurer of the county in which the home is located and also carry out the title application process

Exempt if:

Tax has already been paid

Example

When resold, the new owner does not pay the 5% use tax again.

Installed purchase price

“Installed purchase price” is the amount charged by building contractors to convert manufactured housing from tangible personal property to realty. This includes, but is not limited to, amounts charged for installing a foundation and electrical and plumbing hookups. It does not include any amount charged for landscaping in connection with the conversion.

Modular Homes

Taxable:

6% sales or use tax, plus local option tax if applicable, on 60% of the purchase price

The circumstances of the sale determine who pays the tax.

A dealer who is not a contractor, subcontractor, or installer may purchase modular homes for resale tax free from a wholesaler or manufacturer. Tax is collected when the home is sold.
A dealer who is also a contractor may purchase modular homes tax free for inventory. The dealer will owe tax on the cost of the home when it is withdrawn from inventory for use in a construction contract.
A contractor must pay the tax to the supplier when purchasing a home for use in a construction contract.
A manufacturer that acts as its own dealer will collect the tax on its sales to customers, unless the customer will be reselling the home.
A manufacturer who installs a modular home for an Iowa customer at a construction site in Iowa owes tax on the fabricated costs.

Sectionalized Housing and Panelized Construction

Sectionalized housing and panelized construction are considered prefabricated structures but not manufactured or modular homes. Sales tax is due as with typical construction projects.

Machinery and equipment that do not become real property (remains tangible personal property after installation) must be purchased for resale by providing the supplier with a valid Sales Tax exemption Certificate (31-014). Contractors who sell machinery or equipment that is not exempt from tax must then charge sales tax as part of the contract. The contract must either itemize sales tax separately or state that sales tax is included in the contract price. The contractor must have a sales and use tax permit.

Construction Contracts with Machinery and Equipment

When a construction contract is mingled with a machinery and equipment sales contract (a mixed contract), the two parts should be separated for sales tax purposes. In these contract situations, the contractor is the consumer of the construction materials and is also a retailer of the machinery and equipment. The contractor is required to pay tax on building materials and collect tax from taxable customers on the machinery and equipment.

Example:

Company A contracts with Company B to build a new building and install all of the machinery and equipment. Company B pays its suppliers sales tax on all building materials and supplies. Company B also purchases refrigeration units that will remain tangible personal property after installation. Company B buys these units tax free for resale since they will be resold to Company A; Company B will then charge Company A sales tax on the units.

Distinguishing Machinery and Equipment from Real Property

"Machinery and equipment" includes property that:

Is tangible personal property when it is purchased and remains tangible personal property after installation
Is not permanently annexed to the realty
Can be moved without causing damage or injury to itself or to the structure
Does not in any manner constitute an integral part of a structure

For a list of property that under normal conditions remains tangible personal property after installation, see Appendix D.

Tangible Personal Property that Become Structures

Items that are manufactured as tangible personal property can become structures. The determination is made on an item-by-item basis.

Following is a list of standards used to decide if an item becomes a structure:

Degree of architectural and engineering skills necessary to design and construct the structure
Overall scope of the business and the contractual obligations of the person designing and building the structure
Amount and variety of materials needed to complete the structure, including the identity of materials prior to assembly and the complexity of assembly
Size and weight of the structure
Permanency or degree of annexation of the structure to other real property that would affect its mobility
Cost of building, moving, or dismantling the structure

Example:

A farm silo, which is a prefabricated glass-lined structure, is intended to be permanently installed. The silo is 70 feet high and 20 feet around, weighs 30 tons, and is affixed to a concrete foundation weighing 60 tons that is set into the ground for the specific purpose of supporting the silo. The assembly kit includes 105 steel sheets and 7,000 bolts. The silo can be removed without material injury to the realty or to the unit itself at a cost of $7,000. In view of its massive size, the firm and permanent manner in which it is erected on a substantial foundation, its purpose and function, the expense and size of the task, and the difficulty of removal, it is considered a structure and not machinery or equipment.

Sales Tax and Use Tax

Sales or use tax is computed on the actual selling price of the taxable purchase. The rate for sales and use tax is 6%.

When the tax is imposed determines whether it is a sales tax or a use tax.

Sales tax

Sales tax is imposed when property is delivered in Iowa.

Sales tax is applied when taxable goods are delivered and when taxable services are first used, or potentially could be first used. The Iowa seller of the items must obtain a sales and use tax permit and is primarily responsible for collecting, reporting, and remitting the tax to the Department. In addition, a local option sales tax may apply to sales or services, depending upon where the sale is occurring.

Use tax

Use tax is imposed when property is purchased for use in Iowa but no Iowa sales tax has been paid.

Iowa use tax may be collected by out-of-state retailers who are not obligated to collect sales tax on their sales of goods and taxable services to persons who will use those goods and services in Iowa. If a retailer is not required to collect Iowa tax, anyone purchasing goods or taxable services from that retailer for use in Iowa is obligated to pay use tax at the rate of 6% when those goods or services arrive in Iowa.

See Permit Requirements

Local Option Sales Tax

In addition to the 6% state sales tax, local jurisdictions may impose a local option sales tax (LOST).

Within a county, some cities may have the local option tax, some may not. Also, the unincorporated area of a county may or may not have the tax. The rate is 1%.

The list of local option tax jurisdictions is updated in June and December.

If a contractor receives taxable goods or makes, or potentially could make, first use of taxable services in a local option jurisdiction, the tax must be paid. If a contractor receives taxable goods or makes, or potentially could make, first use of taxable services outside a local option jurisdiction for use inside a jurisdiction, the local option tax of the jurisdiction in which the taxable goods are delivered or where taxable services are first used, or potentially could be first used, is due.

The following are not subject to local option sales tax.

In addition, the state rate remains at 5%:

Self-propelled building equipment, pile drivers, motorized scaffolding, or attachments customarily drawn or attached to them, including auxiliary attachments which improve their performance, safety, operation, or efficiency and including replacement parts.

These must be used directly and primarily by contractors, subcontractors, and builders for new construction, reconstruction, alterations, expansion, or remodeling of real property or structures.

When these items are rented to contractors for use in connection with new construction, reconstruction, alteration, expansion, or remodeling, the rental payments are exempt from tax.

Refund of Local Option Tax

If a local option tax is imposed after a contractor enters into a written contract, the contractor must pay the local option tax applicable at the time it purchases building materials. The contractor may then apply for a refund of the additional local option sales tax based on certain conditions.

All of the following conditions must be met before a contractor is eligible to claim a local option tax refund:

The goods, wares, or merchandise is incorporated into an improvement to real estate in fulfillment of a written contract fully executed prior to the date of the imposition of the local option tax. The refund does not apply to equipment transferred in fulfillment of a mixed contract.
The contractor has paid to the Department or to a retailer the full amount of the state and local option tax.
The claim for refund must be filed with the Department within one year from the date the tax is paid. The IA 843 Claim for Refund (20-843) is used for this purpose.

Tax Liability of Subcontractors

A subcontractor who is providing materials and labor on the actual construction of a building or structure has the same tax responsibilities as a general contractor.

Machinery and equipment sold by material suppliers to subcontractors are sold for resale, and the subcontractor must provide the supplier with a valid Sales Tax Exemption Certificate (31-014). The subcontractor must have a sales and use tax permit.

A general contractor is not responsible for the tax liabilities of a subcontractor.

Filing Sales and Use Taxes

Iowa contractors who are also retailers must have a sales and use tax permit.

Out-of-state contractors required to be registered must have a sales and use tax permit.

Iowa contractors filing sales and use tax returns must report and pay the tax in the period in which the materials were removed from inventory or brought into Iowa from out-of-state.

See Apply for a Permit, Permit Requirements, and Filing Frequencies and Return Due Dates.

Penalty and Interest

Penalty and/or interest may apply if you fail to file a return on time or if you fail to pay the tax due.

Penalties can be waived only under special circumstances. Interest cannot be waived.

See Penalty and Interest.

Building Materials

The term “building materials” means materials used in construction work and incorporated into real property. It is not limited to materials used in constructing a building. It may also include any type of materials used for improvement of the premises or anything essential to the completion of a building or structure for the use intended. Carpeting is not considered to be a building material.

Building Supplies

The term “building supplies” means anything that is furnished for and used directly in the carrying out of the work of an owner, contractor, subcontractor, or builder and is consumed entirely. Such items do not have to enter into and become a physical part of the structure like materials, but they do become as much a part of the structure as the labor performed on it.

The following is a partial list of building materials and supplies:

Asphalt
Bricks
Builders hardware
Caulking material
Cement
Central air conditioning
Cleaning compounds
Conduit
Doors
Ducts
Electric wiring, connections, and switching devices
Fencing materials
Floor covering other than carpeting
Flooring
Glass
Gravel
Insulation
Lath
Lead
Lighting fixtures
Lime
Linoleum
Lubricants
Lumber
Macadam
Millwork
Modular and mobile homes
Mortar

Oil
Paint
Paper
Piping, valves, and pipe fittings
Plaster
Plates and rods to anchor masonry foundations
Plumbing supplies
Polyethylene covers
Power poles, towers, and lines
Putty
Reinforcing mesh
Rock salt
Roofing
Rope
Sand
Sheet metal
Steel
Stone
Stucco
Tile
Wall coping
Wallboard
Water conditioners
Weather stripping
Windows
Window screens
Wire netting and screen
Wood preserver

Building Equipment

The term “building equipment” means any vehicle, machine, tool, implement, or other device used by a contractor in erecting structures for others, or reconstructing, altering, expanding, or remodeling property of others that does not become a physical component part of the property upon which work is performed and is not necessarily consumed in the performance of such work.

The contractor must pay sales, use, or excise* tax on any purchases of building equipment but may rent building equipment exempt from tax.

Rental of the following are exempt when directly and primarily used in new construction, reconstruction, alteration, expansion, or remodeling. This list is illustrative, not exclusive.

Self-propelled building equipment (does not include vehicles subject to registration)
Self-constructed cranes
Pile drivers
Structural concrete forms
Regular and motorized scaffolding
Generators
Attachments customarily drawn or attached to the above
Auxiliary attachments which improve the performance, safety, operation, or efficiency of the equipment and replacement parts
Tools, including hand tools
Compressors
Drill presses
Forms other than structural concrete forms
Lathes

*Instead of the 6% state sales/use tax (and local option tax where applicable), a 5% state excise tax applies to purchases of the following specific construction machinery and equipment:

Self-propelled building equipment
Pile drivers
Motorized scaffolding
Auxiliary attachments which improve the performance, safety, operation, or efficiency of the equipment
Replacement parts for the equipment

Portable Toilet Rental and Servicing

When a construction contractor rents a portable toilet for use on a construction site, the sales price for the rental of the portable toilet is taxable. Because portable toilets are not building materials, supplies, or equipment as described above and do not improve the performance of the machinery or equipment used in construction, they are subject to tax.

When a portable toilet rental company also sells waste removal services and itemizes that service separately on an invoice, the waste removal service is not subject to tax: sewage sludge is excluded from the definition of “solid waste,” the removal of which is otherwise taxable under Iowa Code section 423.2(7). However, if the rental company does not separately itemize the waste removal service and the portable toilet rental in a contract to provide such products and services, the entire sales price is taxable as a bundled transaction under Iowa Code section 423.2(8).

Carpeting

Carpeting is considered to be tangible personal property, not a building material. When contractors are building spec homes, they are the consumers of carpeting and must pay tax to their suppliers.

Purchasing for resale

Contractors may purchase carpeting for resale and provide the seller with a sales tax exemption certificate (31-014). If contractors purchase carpet tax free for resale, they must collect tax from the final consumer.

Contractors must have sales and use tax permits to purchase carpet tax free for resale.

Carpet installation

Carpet installation is exempt from sales tax. However, the bill must be itemized to show that sales tax is being charged on the cost of the carpet only. If the installation charge is not separately itemized, the entire bill is subject to sales tax.

Floor Coverings Other Than Carpeting

Floor coverings other than carpeting are considered to be building materials if they are shaped to fit a particular room and are permanently attached to the floor. When this occurs, they are taxable in the same manner as building materials that are used in the performance of a construction contract.

Sales of linoleum and other types of floor covering other than carpet that are not attached but simply laid on finished floors are subject to tax unless purchased for resale.

Landscaping Materials

The sales price of the sale of sod, dirt, trees, shrubbery, bulbs, sand, rock, woodchips, and other similar landscaping materials are subject to sales or use tax when used for landscaping and sold to final consumers. The final consumer means the owner of the land or a general building contractor.

When a landscaping contractor uses materials to fulfill a contract, the landscape contractor is considered the retailer of the landscaping materials and is obligated to collect sales tax on the selling price from the final consumer.

In the following examples, assume that the contractor is a landscaping contractor.

Example 1:
A sodding contractor furnishes and installs 20 yards of sod at $20 per yard for a total of $400. The sodding contractor also charges the customer $24 sales tax (6% x $400).
Example 2:
XYZ Company landscapes a new office building. XYZ furnishes the shrubs at $25 each, white rock for $5 per bag, and woodchips for $4 per bag. Under a separate contract XYZ installs all of the landscaping materials for a fee of $25 per hour. XYZ’s taxable sales price include the shrubs, white rock, and woodchips. The labor charge is exempt because the taxable service of landscaping is performed on new construction.

Sales of uncut sod and unexcavated trees, shrubs, and rock are not subject to sales/use tax. They are considered to be the sale of real estate.

Property which normally remains tangible personal property after installation.

The list is not complete and is for illustrative purposes only.

Furniture, radio and television sets and antennas, washers and dryers, portable lamps, home freezers, portable appliances, and window air conditioning units
Portable items such as casework, tables, counters, cabinets, lockers, athletic and gymnasium equipment, and other related easily movable property attached to the structure
Machinery, equipment, tools, appliances, and materials used exclusively as such by manufacturers, industrial processors, and others performing a processing function with the items
Office, bank, and savings and loan association furniture and equipment, including office machines
Radio, television, and cable television station equipment, but not broadcasting towers
Certain equipment used by restaurants and in institutional kitchens; for instance, dishwashers, stainless steel wall cabinets, stainless steel natural gas stoves, stainless steel natural gas convection ovens, combination ovens, and steamers with stands
