Cert 141 Form: Key Details and Requirements

The CERT-141 Contractor's Tax Exemption Certificate exists to streamline material procurement for qualifying construction projects in Connecticut. When a contractor signs an agreement with a qualifying entity, such as a Connecticut state agency, municipality, charitable organization, or religious institution, this certificate allows them to acquire tangible personal property without paying sales or use tax. The certificate applies strictly to items that will be physically installed into the construction project and must remain part of the finished structure.

Contractors bear full responsibility for proper use of this certificate. If materials are diverted to a non-qualifying project or removed after completion, the contractor owes use tax on the full price of those items. Sellers who accept the certificate in good faith are protected from liability, provided they keep a copy on file. Both parties should retain records for at least three years, as the CT DRS may audit these transactions during that period.

Qualifying entities that commonly issue contracts for CERT-141 include state government departments, public schools, fire districts, housing authorities, and qualifying nonprofit organizations under Connecticut General Statutes. The certificate must list the specific entity, the project location, and a description of the property being constructed or improved. Contractors working on multiple qualifying projects should file a separate certificate for each one. Related Connecticut tax certificates include the CERT-104 for resale, the CERT-115 for government agencies, the CERT-125 for nonprofit organizations, and the CERT-134 for manufacturing.

Who Can Use This Certificate?

Only contractors who hold a signed agreement with a qualifying entity can use the Cert 141 form. Qualifying entities include Connecticut state agencies, municipalities, public schools, housing authorities, and qualifying nonprofit organizations. Subcontractors may also use this certificate if the general contractor's agreement is with a qualifying entity and the subcontractor is acquiring materials for that same project.

What Happens If the Certificate Is Misused?

If a contractor uses materials acquired under a Cert 141 for a non-qualifying project, the contractor becomes liable for the full Connecticut use tax on those items. The CT DRS can assess penalties and interest on unpaid tax. Sellers who accepted the certificate in good faith are not held responsible.
