Question: How can I change the Sales Tax filing frequency for my business? Why did the department change it?
Your filing frequency for sales tax remittance depends on your sales volume, which is reviewed annually by the department. You may be required to file your sales tax payment monthly, quarterly or annually.

Monthly
$300 or more of sales tax per month.

Quarterly
Under $300 of sales tax per month.

Annually
If after one year of operation, your business collects $15 or less of sales tax per month.

If the amount of tax collected changes, notify the department before the beginning of your next filing period and we will change our records to reflect your new filing frequency.

To request a filing frequency change:
  • Contact our call center (303) 238-7378
  • Mail in a request:

    Colorado Department of Revenue
    ATTN: Business Tax Accounting Section
    1375 Sherman St.

You can now file a Colorado tax return online, view previously filed returns, verify payments made on the account, make payments, file protests and more using Revenue Online.
