The Michigan Department of Treasury reminds taxpayers who filed a 2017 state return they can check the status of their refund online by going to www.michigan.gov/wheresmyrefund.

Those who e-filed can check their refund status two weeks from the date confirmation that the state return was accepted. Paper-filed tax returns can be viewed from six to eight weeks after postmarking.

To ensure taxpayer privacy and security, information required when checking the status of a refund includes the social security number, tax year, filing status, and adjusted gross income or total household resources.

To protect against tax-related identity theft, treasury selects some state income tax returns for identity confirmation. The selected taxpayer will receive a letter asking them to take a short on-line quiz or submit paperwork. When confirmed, the tax refund will be issued in about a month.
