First, be sure that you have a Tax ID in each of the non-streamlined states where you want to collect sales tax.
If you want TaxCloud to file for you in any of those non-streamlined states, please do the following:
1.) Login to your TaxCloud account and go to Settings... Automated Compliance.
2.) Give the page a second to load and then click "Configure Automated Filings". It's located in blue font just below the Automated Compliance 'toggle' switch.
3.) From the list of states that appear, click the switch next to the state's name and enter your business' Login ID and Password for the Department of Revenue website in that state. Then click Save.
