Online Services

Revenue Online is the Colorado Tax Division’s main platform for individuals and businesses to manage various tax needs. This online tool can be used for many tasks, including:

• Check state tax records: You can view current or previous filings, payments, and correspondence with the Colorado Department of Revenue through Revenue Online. You can also send secure messages to the Department while logged into Revenue Online.
• Check my refund status for individual income taxes: Go to Revenue Online’s refund lookup tool (no login is needed) to check the status of your individual income tax refund or your PTC rebate.
• Request a payment plan: Individuals may request a payment plan for their outstanding income tax liability through Revenue Online. Payment plans for business tax debt (such as sales tax and wage withholding) can only be requested by speaking with a Compliance Agent at (303) 866-3711. For more information, see Payment Plan.
• Apply for an out-of-state retailer license: If your business does NOT maintain a physical location in Colorado but makes taxable sales in Colorado, you can apply for a Colorado sales tax license through Revenue Online.
• Register as an out-of-state employer. If your business does NOT maintain an office, saleroom, store, warehouse, distribution center or similar place of business in Colorado but pays wages to Colorado residents or employees who perform work in Colorado, you can register as an out-of-state employer through Revenue Online.

    • For sales and use taxes owed to self-collected cities, you cannot use Revenue Online. You must use the Sales & Use Tax System (SUTS) or pay directly to a local municipality. For cities that do not participate in SUTS, you must reach out to that city to file and pay sales and use taxes.

SUTS (Sales & Use Tax System) is Colorado’s centralized filing system that allows businesses to file sales and use tax returns for the state, state-collected local jurisdictions, and most self-collecting cities through one portal, in a single submission. To see local jurisdictions that participate in SUTS, review the following:

• All state-collected cities participate in SUTS.
• All state-collected counties participate in SUTS. 
• Some self-collecting cities participate in SUTS. For local self-collecting cities that do not participate in SUTS, you must reach out to that city to file and pay sales and use taxes. 

If you would like additional assistance, visit get help using SUTS.

GIS (Geographic Information System) is an online map-based tool you can use to look up sales and use tax rates for any location in Colorado.

In Colorado, both state and local municipalities may have taxes that apply to your business. Depending on your specific business, you may need to go directly to a local municipality to handle your local taxes. Use local government websites for the following:

• Check local tax records: If you need to check your account records for current or previous filings and payments related to local sales and use taxes, you will need to contact your local municipality. This information is not stored in Revenue Online nor SUTS.
• File and remit local sales and use taxes directly: While many local sales taxes can be submitted through Colorado Department of Revenue systems (Revenue Online and SUTS), some cities have not opted into our online systems. To see which self-collecting cities do NOT participate in SUTS, scroll to the bottom of self-collecting cities. 
  • For self-collecting cities that do NOT participate in SUTS, you are required to file and pay through their local municipalities. 
  • For all self-collecting cities that do participate in SUTS, you can choose to file and pay through SUTS or directly with each local municipality.
