Municipal Code relating to Sales and Use Tax.
The City of Longmont is located in two counties with four corresponding USPS zip codes, two of which also appear in areas outside of the city and do not coincide with city boundaries. However, in some cases they do use “Longmont” as the city name. Therefore, you cannot rely upon the mailing address and zip code to determine whether or not a particular location is within the city boundaries (link to page with boundary map). This can cause difficulties in determining whether or not a transaction is subject to the City of Longmont Sales Tax.
Businesses are liable to the City for Sales Tax that is under collected. As such, we would like to make you aware of the electronic location databases that have been certified by the Colorado Department of Revenue pursuant to Colorado Revised Statutes 39-26-105.3 to determine the correct jurisdiction for sales tax purposes. The City of Longmont, along with several other municipalities, has put in place provisions which will hold harmless businesses that collect the incorrect amount of Sale Tax if they can offer proof that the most current version of these databases was used and provided the incorrect information for a particular address.
For additional information about using currently certified database providers, along with links to these provider’s websites, please visit the Colorado Department of Revenue.
