Questions people ask
Can I use Form 4908 to amend my return?
No. Use the CIT Amended Return for Financial Institutions, Form 4909.
What if I have no Michigan gross business?
Enter zero on line 9a.
Can I apply an overpayment to next year instead of receiving a refund?
Line 37 lets you enter the amount of the line 36 overpayment to credit forward as an estimated payment for the next tax year. Line 38 calculates the refund by subtracting line 37 from line 36.
