I will be required to pay the contractor the appropriate sales tax on tangible personal property (and any associated services) when the property installed by the contractor does not become a permanent part of the real property; AND

I will be subject to civil or criminal penalties (or both) under the Tax Law if I issue a false or fraudulent certiicate.

When the customer completes this certiicate and gives it to the contractor, who accepts it in good faith, it is evidence that the work to be performed will result in a capital improvement to real property.

A capital improvement to real property is an addition or alteration to real property that:

(a)substantially adds to the value of the real property or appreciably prolongs the useful life of the real property, AND

(b)becomes part of the real property or is permanently afixed to the real property so that removal would cause material damage to the property or article itself, AND

(c)is intended to become a permanent installation.

The work performed by the contractor must meet all three of these requirements to be considered a capital improvement. This certiicate may not be issued unless the work qualiies as a capital improvement. See Tax Bulletin Capital Improvements


If a contractor performs work that constitutes a capital improvement, the contractor must pay tax on the purchase of building materials or other tangible personal property, but is not required to collect tax from the customer for the capital improvement. No credit or refund is allowed for the tax paid on the cost of materials by the contractor. See Tax Bulletin Contractors – Sales Tax Credits (TB-ST-130).

For guidance as to whether a job is a repair or a capital improvement, see Publication 862, Sales and Use Tax Classiications of Capital Improvements and Repairs to Real


A contractor, subcontractor, property owner, or tenant, may not use this certiicate to purchase building materials or other tangible personal property tax free. A contractor’s acceptance of this certiicate does not relieve the contractor of the liability for sales tax on the purchase of building materials or other tangible personal property subsequently incorporated into the real property as a capital improvement unless the contractor can legally issue Form ST-120.1, Contractor Exempt Purchase Certiicate. (See

Publication 862 for additional information.)

The term materials is deined as items that become a physical component part of real or personal property, such as lumber, bricks, or steel. This term also includes items such as doors, windows, sinks, and furnaces used in construction.

Floor covering

Floor covering such as carpet, carpet padding, linoleum and vinyl roll looring, carpet tile, linoleum tile, and vinyl tile installed as the initial inished loor covering in new construction, a new addition to an existing building or structure, or in a total reconstruction of an existing building or structure, constitutes a capital improvement regardless of the method of installation. As a capital improvement, the charge to the property owner for the installation of loor covering is NOT subject to New York State and local sales and use taxes. However, the retail purchase of loor covering (such as carpet or padding) itself is subject to tax.

Floor covering installed other than as described above does not qualify as a capital improvement. Therefore, the charges for materials and labor are subject to sales tax. The contractor may apply for a credit or refund of any sales tax already paid on the materials.

The term loor covering does NOT include looring such as ceramic tile, hardwood, slate, terrazzo, and marble. The rules for determining when loor covering constitutes a capital improvement do not apply to such looring. The criteria stated in (a), (b), and (c) above apply to such looring.

Temporary facilities at construction sites

Subcontracts to provide temporary facilities at construction sites that are necessary for the construction of a capital improvement are considered to be part of the capital improvement project.

Examples of temporary facilities include temporary:

heat, electric, or plumbing services;

protective pedestrian walkways; and

scaffolding services.

A primary contractor purchasing qualifying temporary facilities from a subcontractor must give the subcontractor a copy of Form ST-124 issued to the primary contractor by the customer (including a customer that is an exempt organization) to purchase the subcontractor’s services exempt from tax.

A certiicate is accepted in good faith when a contractor has no knowledge that the certiicate is false or is fraudulently given, and reasonable ordinary due care is exercised in the acceptance of the certiicate.

If a contractor gets a properly completed Form ST-124 from the customer within 90 days after rendering services, and accepts it in good faith, the customer bears the burden of proving the job or transaction was not taxable.

If you are a contractor who installs items such as washing machines, clothes dryers, dishwashers, refrigerators, furniture, etc., which when installed or placed in real property do not become part of the real property, you must collect tax on your charge for the installation. The individual charge for any of these items is also taxable as the sale of tangible personal property.

If a contractor does not get a properly completed Certiicate of Capital Improvement within 90 days, the contractor bears the burden of proving the work or transaction was a capital improvement. The failure to get a properly completed certiicate, however, does not change the taxable status of a transaction; a contractor may still show that the transaction was a capital improvement.

Contractors and subcontractors must keep any exemption certiicate for at least three years after the due date of the last return to which it relates, or the date the return was iled, if later. The contractor must also maintain a method of associating an exempt sale made to a particular customer with the exemption certiicate on ile for that customer.
