Minnesota has combined its sales and use tax refund claim forms into one form, Form ST11, Sales and Use Tax Refund Request and Multiple Period Amended Return. Form ST11 can be used to request capital equipment refunds, purchaser sales tax refunds, and special purchase refunds. Form ST11 can also be used by taxpayers to amend their returns for multiple periods, so they no longer need to make changes to individual returns in e-Services. The following forms have been discontinued: Form ST11P, Special Purchase Refund Claim; Form ST11-PUR, Purchaser Sales Tax Refund Claim; and Form ST11-UL, Utilities Sales Tax Refund Claim. The Form ST11 can be accessed here. (Email and Revised Form ST11, Sales and Use Tax Refund Request and Multiple Period Amended Return, Minnesota Department of Revenue, December 12, 2014)
