You must provide the website with your Social Security number or individual taxpayer identification number, the tax year you're checking and the dollar amount of your refund. You also need to specify that you are inquiring about your income tax refund rather than a property tax return.
When you file your Minnesota tax return, you can request your refund be directly deposited in a bank account or have a check mailed to you. If the bank account listed on your return is closed before the refund is issued, the Minnesota Department of Revenue will mail you a check. You also have the option to have your refund applied to your taxes due for the following year. If you did that by accident, you'll need to request the refund in a letter to Minnesota Revenue, Mail Station 5510, St. Paul, MN 55146-5510. There's no official form, but you should include your identifying information and that you didn't intend to have your refund withheld for the following tax year. If you don't typically make estimated payments, the Minnesota Department of Revenue will usually grant your request.
