The Michigan Financial Information Form (FIF) is a document used by individuals and businesses who are filing tax returns to the state of Michigan. It is used to report income, deductions, and any other financial information that may be applicable. The form is available in both paper and electronic versions. There are three types of Michigan Financial Information Forms: the Individual FIF, the Partnership FIF, and the Corporate FIF. The Individual FIF is used to report income and other information for an individual taxpayer filing a Michigan income tax return. The Partnership FIF is used by general partnerships to report income and other information on their Michigan income tax return. The Corporate FIF is used by corporations to report their income and other information on their Michigan income tax return. All three forms require the taxpayer to provide detailed information about the various sources of income, deductions, and other financial information.
