Denver sales tax for businesses: official lookups, filing and event sales
Check the selling or delivery location and the product before choosing a rate or filing route. Denver administers its own taxes and accepts sales/use filings through SUTS with specific limitations.
Sources checked . General information maintained by Denver Tax with AI assistance. We are an independent directory, not a government agency or tax adviser. Verify the instructions for your tax year and circumstances.
Look up the actual address, then check the transaction
Use Colorado’s official lookup instructions to find sales/use rates and location codes for an address. GIS can identify state, county, municipal and special-district components. A Denver postal address or ZIP code alone is not a reliable substitute for that lookup.
Next, describe what you sell and where the sale or delivery occurs. Denver’s general rate table has separate treatment for some products and activities. A general combined rate does not establish the correct treatment for every item, exemption or transaction.
The Colorado local-tax guidance distinguishes state-collected taxes from self-collected local taxes. A self-collected home-rule city may have its own taxability rules. Check the relevant city’s instructions as well as the state guidance, particularly when selling in more than one jurisdiction.
Denver eBiz and Colorado SUTS serve different tasks
Denver’s business-tax page links to eBiz for managing city tax accounts and filings. Denver also participates in Colorado’s Sales & Use Tax System (SUTS) for sales/use taxes. Being a self-collected city does not mean Denver is outside SUTS.
The City identifies limits: refund claims, amendments and delinquent periods go directly to Denver; its other taxes are outside SUTS. When using SUTS, follow Denver’s instructions for the local jurisdiction line and account number. Check filing frequency and the period on your actual account instead of assuming the same schedule applies to every seller.

Printable checklist for a Denver event seller
Use your browser’s Print command to keep this checklist. Check both the Denver event FAQs and the state special-event resources; organizer instructions do not replace the relevant authority’s requirements.
- Record the event name, exact selling address and dates. Confirm whether you are inside Denver’s jurisdiction.
- List what you sell, how customers receive it and whether a marketplace or organizer handles any collection. Confirm responsibilities rather than assuming they do.
- Check the city and state registration or special-event requirements, including how an existing sales-tax account affects the process.
- Confirm the applicable taxability, rate, filing period and return instructions with the authority. Ask about requirements even if no tax is due.
- Keep sales totals, refunds, exempt-sale support where applicable, tax collected and payment/filing confirmations in your business records.
- Assign responsibility for reconciling and filing after the event; keep a note of the official deadline for your account.
This checklist helps organize questions. It does not decide nexus, an exemption or your liability.
What help should you ask for?
A bookkeeper can be asked about reconciling sales channels, refunds, tax collected and payments; an accountant or tax preparer can be asked about filing scope and unresolved tax questions. Confirm the actual services each practice offers.
Ask whether the engagement covers Denver and other relevant jurisdictions, who maintains taxability decisions, who submits returns and how errors or notices are handled. Separate a one-time cleanup quote from the recurring bookkeeping fee. Mention employees separately, because payroll and occupational privilege tax are different tasks from sales-tax filing.
Ask a professional about your situation
Ask whether the practice handles the specific return or filing you need, what the written quote includes and how documents are shared securely. A category listing does not establish credentials or experience with this tax.
