Denver Sales Tax 2026: Small Business Guide (8.81% combined rate)
Complete Denver sales tax guide. State + local breakdown, filing rules, nexus thresholds, and which agency collects.
If you sell goods or taxable services in Denver, Colorado, sales tax compliance is split between state and local agencies. Here's the breakdown — 2026 edition.
Current Denver combined rate: 8.81%
Breakdown of the 8.81% rate:
- State of Colorado: 2.9%
- Local portions (county + city + special districts): 5.91%
- Combined rate at point of sale: 8.81%
Important note for Denver: Destination-based. Denver is home-rule — has its own collection system separate from state.
Who must collect sales tax in Denver?
You have nexus and must collect if any of these apply:
- You operate a physical location in Denver or surrounding jurisdictions
- You have an employee or contractor based in Colorado
- You store inventory at an FBA warehouse in Colorado
- Your Colorado sales exceed the state's economic nexus threshold (typically $100,000 or 200 transactions)
Destination-based vs origin-based
Denver is in a destination-based state — you charge the rate at the customer's delivery address, not yours.
This matters for online and multi-location businesses: tracking dozens of local rates becomes a pain without software.
Special Denver taxes
In addition to general sales tax, be aware of:
- Liquor/tobacco: excise taxes on top of sales tax
- Vehicle/fuel: separate regimes entirely
Filing: state vs local
Denver is a home-rule city, meaning it collects and enforces its own sales tax separately from the Colorado Department of Revenue. You must:
1. Register with the Colorado Department of Revenue for state tax
2. Register separately with the Denver tax office
3. File two returns — state and local
Filing frequency
Assigned by the state based on expected liability:
- Monthly: larger collectors
- Quarterly: mid-size
- Annually: smallest sellers
Returns are typically due by the 20th of the month following the period. Missing a deadline: ~10% penalty + interest.
Common pitfalls in Denver
- Using your business's ZIP code rate when you should use the customer's (destination-based states)
- Missing local-only taxes like hotel/meals
- Not knowing about Denver's special industry rules
- Failing to track local rate changes (some local portions change quarterly)
