What our program is and is not
Our Colorado system is designed to file the CO state level DR-0100 form, specifically for multi-location businesses that need to file a DR-0100 for each location, which is a time-consuming task.
Our system allows you to upload your DR-0100 forms in a spreadsheet, and efileSalesTax.com processes that spreadsheet into a file that the Colorado DOR accepts (an XML file).
The state's efiling system that we are integrated with doesn't yet support filing down to the sub-state locations, so until they do, we can't offer that granularity of sales tax filing. Only the state sales tax DR-0100 form.
Also, our Colorado system does not currently look up tax rates and jurisdictions. You are required to enter all the rates, sales, deductions, etc. (basically each field from the DR-0100 form)
We will keep you informed when this becomes available, as long as you register for a free account at our site, and give us permission to email you. (We hate spam, and don't send many emails)
