Because contractor's excise tax is owed on your gross receipts, which include any taxes collected from the customer, a bid factor of 2.041% may be used to calculate the excise tax when preparing a bid or bill. This allows you to collect the full amount of excise tax due.
Prime Contractor’s Exemption Certificate
Except for projects for a qualified utility, it is the prime contractor’s responsibility to issue prime contractor's exemption certificates to all subcontractors for each project. If a subcontractor hires another subcontractor, the prime contractor must issue the exemption certificate. The exemption certificate must show the prime contractor’s excise tax license number, the project location, and description. A blanket certificate cannot be issued to a subcontractor, it must list the specific project.
Subcontractors that do not have a certificate on file for a project are considered prime contractors and are subject to the contractor's excise tax. The department recommends obtaining a prime contractor's exemption certificate prior to starting work.
A full list of statistical reports on Excise Taxable Receipts by SIC can be found on the Historical Tax Statistical Reports Page. In all cases when you select a month, you will be viewing data compiled from returns filed with the Department during that month.

If the utility company receives funding from an outside source and the utility company pays the prime contractor, the project is taxed as a qualified utility project.

Contractors do have to report the value of material furnished by the owner of the construction project, except for qualified utility projects. The fair market value of the owner-furnished material includes sales or use tax on the material.
Contractors also owe state and applicable municipal use tax on all material furnished for a construction project if they do not have documentation showing sales or use tax was paid. Documentation may include a copy of the invoice showing tax or a written statement from the owner that sales or use tax was paid. Contractors will owe use tax on material furnished by a government or other sales tax exempt entity because the government will not have paid sales tax at the time of purchase. Contractor's excise tax and use tax due on owner-furnished material is reported during the reporting period the material is furnished for the contractor’s use.
