Sales Internet Process (SIP) has been discontinued
Effective July 1, 2009, the Sales Internet Process (SIP) has been discontinued.
The Wisconsin Department of Revenue has transitioned to a new on-line product for business taxes, known as "My Tax Account." "My Tax Account" will allow you to file and pay not only sales and use tax returns, but also returns for withholding tax, premier resort area tax, local exposition center tax and state rental vehicle fee. You will also be able to view filing and payment history for all of these tax programs regardless of how they were filed, reprint selected correspondence that DOR has sent you and initiate requests to the department such as to change your address or enter into an installment agreement.
You are required to register for a new logon ID to associate to the new system. For instructions on how to register to use "My Tax Account," CLICK HERE.
