If a Jurisdiction requires that a taxpayer file a "Zero Return" for periods where no sales tax is due, the use of SUTS does not affect this requirement. Please contact the Home Rule Jurisdiction directly with any questions about your businesses liability to report zero sales. Instructions for filing a zero return can be found on the first tab of the Excel Upload Template.

Licenses issued by the Colorado Department of Revenue are valid for state sales taxes and all state-administered local sales taxes. Visit the Department's website for information on registering with the Department and adding locations.

Local sales tax and business licensing requirements vary. Whether a local license is required often depends upon factors such as the nature of your business, and whether you have locations or employees in the jurisdiction. You are responsible for determining whether your business activity in a local jurisdiction requires a local license or registration prior to engaging in that activity.

SUTS does not require you to obtain local licenses prior to filing. Local jurisdictions may contact you using information provided in SUTS regarding local licenses or other local requirements.  If you have more questions please feel free to Contact Us.

Some Home-Rule municipalities impose a special tax rate for certain categories of sales, such as food, marijuana, etc. Sales in these alternate rate categories cannot be reported using SUTS. SUTS only calculates the general Sales Tax rate for each municipality. Please contact the municipality directly to remit taxes using these special rates.
