Question – I know it says you don’t need sales tax for online orders going out of state in Illinois, so does that mean you need to use it for online in state?
Our Answer –
If you ship product from Illinois then you would need to collect sales tax for any orders shipped to Illinois residents. You will need the Illinois business tax number for any sales and you will report both total sales and sales that you collect sales taxes.
Here is a little more information from the Illinois department of revenue. http://tax.illinois.gov/Businesses/TaxInformation/Sales/rot.htm
