Colorado home-rule sales tax: why some cities need a second return.

State-collected vs. home-rule cities

Colorado’s sales tax has layers: the 2.9% state rate, plus county, special district and city taxes. For most of those layers, the Colorado Department of Revenue collects the tax for everyone, so you file one return.

Home-rule cities are different. Under their own charters, many of them administer and collect their own sales tax. They issue their own licenses, set their own rules on what’s taxable, and expect their own return, separate from your Colorado return.

Three south metro examples

Here’s how different it looks within about 20 miles:

Rates as published by each jurisdiction in 2026. Centennial voters decide on November 3, 2026, whether to raise the city rate from 2.5% to 3.5%. Always confirm the rate for a specific address before you set it up.

What changes in your books

1. Separate tax accounts

If you collect tax for a home-rule city, track it separately from the state, county and special district taxes. In QuickBooks Online or Xero, that means separate tax agencies and rates, so each return ties to its own balance.

2. Separate licenses and filing dates

A home-rule city usually requires its own license or registration, and its filing frequency may not match your state schedule. Centennial, for example, requires every business operating in the city to hold either a city sales tax license or a business registration.

3. Deliveries follow the buyer

Since 2019, Colorado sales are generally sourced to where the buyer receives the goods. A Highlands Ranch business delivering into Centennial or Castle Rock may owe those cities’ taxes on those sales, so tag sales by delivery location.

4. Contractors face extra rules

Many home-rule cities collect use tax on construction materials when a building permit is issued. Contractors who show that permit to suppliers can avoid paying the local tax twice.

Filing: SUTS or directly with the city

The state’s Sales & Use Tax System (SUTS) lets you file returns for participating home-rule cities in one place. In the south metro, Centennial, Littleton, Lone Tree, Castle Rock, Parker, Englewood, Greenwood Village and Lakewood are listed as participating. Denver and Aurora aren’t on the state’s list, so returns for those cities go directly to the city.

A quick checklist

1. Look up the exact rate for each address where you sell or deliver.
2. Get a Colorado sales tax license, plus a license or registration in each home-rule city where you do business.
3. Set up a separate tax agency and rate in your accounting software for each jurisdiction.
4. Tag sales by where they’re delivered or picked up.
5. File each return on its own schedule, through SUTS where the city participates.
6. Reconcile each tax account to its return every month, so balances never drift.
