C Corporations New filing Deadlines
If you operate your business as a C Corporation, you now have until April 18th, 2017 to file the 2016 calendar year end business tax return with the IRS. For State of Michigan tax purposes, the deadline remains at April 30th, 2017. If an extension of time is necessary, you will want to file IRS Form 7004. You must pay in any tax due with the extension. For State of Michigan taxes, the extension is requested on CIT Form 4 and if you estimate any tax due it must also be paid with the extension in order to be valid.
