I started an ecommerce site and incorporated in Delaware based on reading advice on various message boards. I am physically located in Chicago. Now that I am doing my business taxes, TurboTax asks me for an Illinois Business Registration number. I did not register my business in Illinois. Questions:
- What is the difference between incorporation and registration of the business?
- In my case, do I need to register in Illinois despite being incorporated in Delaware?
- Also, I have collected sales tax for items sold to people with an IL address, how do I go about giving it to the state?
Thanks very much in advance for any advice.
