MI HB6346

Creates a refundable tax credit for eligible taxpayers who filed 2021 tax year returns, consisting of $500 per household plus $100 per qualifying dependent claimed on that return.

Limits eligibility to Michigan residents with adjusted gross income of $125,000 or less (single return) or $250,000 or less (joint return), excluding individuals claimed as dependents by others.

Requires refund payments to be issued by September 30, 2023, disbursed via direct deposit if authorized on the 2021 return or by check mailed to the filer's address.

Mandates the department send written notice within 15 days of distributing each refund payment, specifying the payment method, amount, and department contact information.

Requires filers to include Social Security numbers for themselves (and spouses on joint returns) and for all claimed dependents to receive the refund payment.
