How soon after I register my business will I be issued a Certificate of Registration or License?

This depends on what method you use to file your application, the number of registration applications that we are currently processing, and whether we have all the information we need to process your application.

If we have all the information that we need and you register online or in person, you should receive your Certificate of Registration or License electronically or through the mail, depending on tax type, within two weeks after we process your application. If you register in person you should receive the tax Account ID or License Number that day. If you register online, you should receive an email with your tax Account ID or License Number in approximately two business days. You can create a MyTax Illinois account the day after you receive notification of your tax Account ID or License Number. From within MyTax Illinois, you can print your Certificate of Registration or License by selecting "View more account options" and then "View Account Letters" in the "Letters and Messages" panel.

If you register by mail or fax, you should receive your Certificate of Registration or License electronically or through the mail, depending on the tax type, in approximately six to eight weeks.

If you are unable to print a copy of your Certificate of Registration or License, you can also contact our Central Registration Division to request a paper copy be mailed to you at 217 785-3707 or by email  by using the "Questions, Comments, or Request" link at the bottom of this page. Please include your Illinois account ID or license number and business name in your request.

For more information see the Business Registration web page. 

If you have additional inquiries, you may submit them to the Questions, Comments, or Request form.
