Rental Surcharge

The rental surcharge is imposed on machinery rented within Connecticut by a rental company to a lessee for a period of less than 365 days or under an open-ended contract for an undefined period of time. The rental surcharge is imposed on the total amount the rental company charges the lessee for the rental of the machinery. The rental surcharge is in addition to any tax otherwise applicable to any rental, and is includable in the measure of the sales and use taxes imposed under Chapter 219.

For the purpose of the rental surcharge on a daily rental of machinery, the period for the term of a machinery rental begins on the date a piece of machinery is rented to a lessee and terminates on the date the piece of machinery is returned to the rental company. Therefore, if a rental of a piece of machinery is renewed before the machinery is returned to the rental company, the term of the renewal is added to the term of the initial rental to determine the rental period. The rental is not subject to the rental surcharge if the initial rental of a piece of machinery:

  • Is for a term of less than 365 consecutive calendar days, and
  • After adding the renewal term to the initial term, the rental period is 365 consecutive calendar days or more.

Machinery means all equipment owned by a company that qualifies as a rental company including, but not limited to, bulldozers, earthmoving equipment, well‑drilling machinery and equipment, or cranes. The term “equipment” should be given its commonly understood meaning and include the implements (machinery and tools) used in operation or activity. Such activities include, but are not limited to, construction, mining, and forestry.

For additional information, see OCG1, Office of the Commissioner Guidance Regarding the Rental Surcharge.

Surcharge Rate

The rental surcharge rate for the rental of machinery is 2.75%.
