Michigan

Extension for tax year 2011

General Instructions

The Michigan Department of Treasury does not require that you file for an extension if you are filing for a Federal extension. Michigan automatically grants a six month extension of time to file until October 15, 2012.

However, to avoid interest you must pay your current year tax liability in full by April 15, 2012. Any tax not paid by the original due date of the Michigan return will be assessed interest and may be subject to additional penalties.

Penalty and Interest Charges on Tax Owed:

• Interest will be assessed on unpaid balances at a rate of 1 percent above the prime rate and is adjusted on July 1st and January 1st. Interest will accrue from April 15, 2012 until the date of payment. Interest accrues regardless of an approved extension request.
• An additional Late Payment Penalty of 5 percent of tax due is incurred. The penalty increases by an additional 5 percent per month or a fraction thereof, after the second month, to a maximum of 25 percent for failure to pay; 10 percent for negligence; or 25 percent for intentional disregard of the law.

Simply attach a copy of your Federal extension form to your Michigan return when you file.
