REQUIRED DOCUMENTATION:
Note: The documentation requirements and examples listed
cover the most frequent claim types. The documentation
required will depend on the reason for overpayment. Some
claims may require additional information or a combination
of the documentation outlined.
Overpayment reasons such as duplicate payment (exact
same amount), a vendor’s fee paid in error, or a payment data
entry error, would not require the documentation outlined.
An example of payment data entry error would be you
intended to pay $5,000.00 and made an EFT payment for
$50,000.00.

If you are applying for a refund from multiple periods and
multiple site locations, the invoices and related information
must be separated by period and location. Each period’s data
must be totaled separately.
Note: To reduce errors and for faster processing, electronic
spreadsheets are preferred (CD or USB).
6. Amended Returns
You must submit amended returns for each applicable
period and include separate returns for each site
(location) involved in the refund claim. The department
requires that the refund request match the sites
(branches) that are set up on the account otherwise the
refund request cannot be processed. To verify your sites,
go to www.Colorado.gov/RevenueOnline, and select
"Find Sales and Use Tax Rates" under the Sales and
Use Tax category then select "View Business Location
Rates". You will be able to view all open sites. Any closed
sites will not show in the search. The site (where the tax
was remitted) must correspond to the appropriate site in
the refund request.
