The deadline for filing state taxes in Minnesota is typically April 15 of each year. However, if that date falls on a weekend or a holiday, the deadline may be extended to the next business day. It is important to remember that extensions can be filed, which allows taxpayers additional time to complete their returns. While this extension gives more time to file, it does not extend the deadline for payment of any taxes owed. Taxpayers should ensure that they pay any estimated taxes by the original deadline to avoid penalties and interest. For the most accurate and up-to-date information, it is advisable to check the official Minnesota Department of Revenue website, where specific details regarding deadlines and filings are available.
