Effective May, 20, 2015, the State of Michigan has disabled the Electronic Payment System, Payconnexions, Web site link
www.michigan.gov/biztaxpayments, and the Interactive Voice Response System (IVR) for Sales, Use and Withholding Taxes (SUW). All future Sales, Use and Withholding payments should be made online through MTO. This information only applies to accounts registered to electronically pay taxes using the Electronic Funds Transfer (EFT) Debit method. Retrieve the updated
Company ID/Debit Block Numbers effective January 2015.
EFT Credit payments are still accepted, but some changes have been made for SUW filers. Please view the updated
EFT Credit Instructions for Michigan Business Taxes (Form 2329) and go to Appendix A (page 4) of the instructions to determine if the tax type you are making an EFT credit for, in tax year 2015, has an updated financial institution account number.
