Sales and Use Tax

As a home rule city, Westminster administers and collects its own taxes.

Sales Tax

Generally the 3.85% city sales tax must be collected on all sales, leases or rentals of items in the city, including items delivered into the city. Certain services, such as cable TV, telephone, gas and electric services, are also taxable. Professional services such as legal, advertising and accounting services are generally not taxable. Learn more about Westminster sales tax.

Use Tax

The 3.85% use tax is due on tangible personal property, such as supplies, fixtures, furniture, equipment, and taxable services that are used, stored or consumed in the city. If Westminster sales tax is not paid to a vendor licensed and authorized to collect the same at the time of purchase, then a use tax must be remitted directly to the city. Credit may be taken against Westminster use tax for legally imposed sales or use taxes paid to other municipalities. Such credit may not exceed the Westminster use tax due. Transactions exempt from the city sales tax are also exempt from the city use tax. Learn more about how to compute Westminster use tax.
