Local taxes and TABOR
Colorado tax questions are layered by design.
Short answer: the exact address controls many Colorado tax answers. State, county, city, home-rule, and special district rules can all overlap.
TABOR in plain English
TABOR is Colorado's Taxpayer's Bill of Rights. It affects when governments need voter approval for tax increases and what happens when revenue exceeds limits. It is why Colorado tax conversations often mention refunds, retained revenue, and ballot questions.
Local taxes are not uniform
Colorado cities and counties can have different sales and use tax rates. Some home-rule cities administer local sales tax themselves. Special districts can add sales tax or property tax in specific areas.
City income tax is not the main Colorado pattern
Colorado's local-tax questions are usually about sales and use taxes, lodging taxes, occupational privilege taxes such as Denver's employee/employer tax, and special district taxes.
What to check
- State, county, city, and special district sales tax for the address.
- Home-rule city collection rules for business activity.
- Use tax on vehicles, building materials, or large purchases.
- Lodging and short-term rental taxes in resort areas.
- Property-tax districts and mill levies on the parcel.
FAQ
Quick answers
Does Colorado have city income tax?
Colorado generally does not have broad city income tax returns. Denver has an occupational privilege tax, and local sales, use, lodging, and district taxes can matter a lot.
Does TABOR mean taxes cannot go up?
No. TABOR sets voter-approval and revenue-limit rules, but voters can approve taxes, local districts can have separate authority, and assessed values can still move.
Why is the sales tax different across the street?
The address may be in a different city, county, special district, or home-rule jurisdiction.
