Minnesota Request For Extension (MN RFE) is an online filing system offered by the Minnesota Department of Revenue that allows individuals and businesses to apply for an extension of time to file their taxes. There are two types of MN RFE: 1. Automatic Extension: An Automatic Extension provides an additional seven months (until October 15) to file your tax returns. This type of extension does not require you to submit any paperwork or payment. 2. Extension Request: An Extension Request allows you to request an additional six months (until December 15) to file your tax returns. This type of extension requires you to submit a completed Extension Request form and payment to the Minnesota Department of Revenue. When applying for a Minnesota Request For Extension, taxpayers must provide their name, address, Social Security number, and the type of tax return they are filing. Once the request is approved, taxpayers will receive a confirmation letter and have the additional time to submit their returns.
