Sales Tax FAQs
Boulder is a locally-collected/administered home-rule city, and as such the state's new rules do not apply to the city's nexus criteria.
The City of Boulder has not amended its code or otherwise changed its physical presence standards.
Currently, the City of Boulder has not followed or otherwise conformed with Colorado's approach to changing its nexus standards and licensing requirements. However, Boulder and other Colorado home-rule cities are currently in discussions about the implications of Colorado's emergency rule for home-rule city tax collection by remote sellers.
Our nexus standards are still outlined in the city code as follows:
BRC 3-1-1. - Definitions Engaged in business in the city means performing or providing services, or selling, leasing, renting, delivering, or installing tangible personal property for storage, use, or consumption within the city.
Engaged in business in the city includes, without limitation, any one of the following activities by a person: (a) Directly, indirectly, or by a subsidiary, maintaining a building, store, office, salesroom, warehouse, or other place of business within the city; (b) Sending one or more employees, agents, or commissioned sales persons into the city to solicit business or to install, assemble, repair, service, or assist in the use of its products, or for demonstration, or for any other reason; (c) Maintaining one or more employees, agents, or commissioned sales persons on duty at a location within the city; (d) Owning, leasing, renting, or otherwise exercising control over real or personal property within the city; or (e) Making more than one delivery into the city within a twelve-month period by any means other than a common carrier.
If you choose to become licensed voluntarily, these city nexus standards notwithstanding, access the license application .
Our main purpose is to provide customer service in order to assist the Boulder taxpaying community with sales, use and various other tax reporting requirements required by Chapters 3-1 through 3-7 of the Boulder Revised Code (B.R.C, 1981). The division provides business licensing services and collects and accounts for a variety of tax revenues.
Key Functions of the Sales & Use Tax Division include:
- Collection of sales, use and other taxes; provide tax return preparation and business licensing assistance; process and account for tax returns filed.
- Provide construction use tax reconciliation return filing support; process and review tax returns.
- Tax collection and delinquent filing processes - contact delinquent taxpayers and work with them to bring the accounts into compliance.
- Conduct tax audits - the division has an active audit program designed to educate taxpayers in order to improve reporting compliance and to recover unpaid tax revenue.
- Conduct new business reviews - an educational opportunity between the taxpayer and the City to educate and assist businesses in understanding tax reporting requirements they may not be familiar with and to answer tax related questions.
- Provide information - answer various tax related reporting and licensing questions from taxpayers.
- Provide information regarding the sales and use tax portion of the Boulder municipal code.
The City of Boulder Revised Code requires that all types of businesses in Boulder be licensed and approved by the City before operating. If a business has more than one location in the city, each location needs a separate license.
Regardless of the filing frequency, tax returns are due by the 20th of the month following the period collected. A zero return must be filed to satisfy the filing requirement even when there is no tax due. If the return is not filed, or filed after the due date, penalty and interest will accrue. Please note the City of Boulder does not accept postmark date as proof of timely filing.
Filing frequency is determined by average tax due. Please notify us via email if the business needs a filing frequency change.
|If average tax due is:||Filing Frequency:|
|$300 or more per month||File Monthly|
|$15-$300 per month||File Quarterly|
|$15 or less per month||File Annually|
Sales tax should be charged on all retail sales of tangible personal property, rentals, and leases of equipment. Some services such as cable TV, telephone, maintenance contracts, gas and electric are also taxable.
Use tax information can be found here: TR 43: Use Tax.
