The Maryland Inventory Supporting Schedule (MISS) is a document used by Maryland taxpayers to report their business inventory for the purpose of calculating their state tax liability. MISS is a form of the State of Maryland's Inventory Tax Relief Program, which allows eligible taxpayers to claim a credit for the cost of their inventory. There are two types of MISS: the MISS-1, which is used to report inventory held by a business on January 1 of a taxable year, and the MISS-2, which is used to report inventory purchased or produced during the taxable year. Both forms require taxpayers to provide detailed information on the inventory they hold, including descriptions of the items, the date acquired, the cost, and the quantity. The MISS forms must be filed by the due date of the taxpayer's Maryland income tax return.
