Welcome to the Illinois Department of Revenue
We'll contact you by mail if we need more information to process your return. The Montana Department of Revenue is unable to assist in securing your stimulus payment. The My Revenue Tax return portal will no longer be available after July 23, 2021. Department of Revenue forms will be made available on MTRevenue.gov. Please contact us if you need additional assistance. Your rebates are based on the 2020 return, but you receive only half the amount of each rebate. We split the rebates equally between you and your ex-spouse (following Idaho Community Property law ). Tax return forms and supporting documents must be filed electronically or submitted on paper. Do NOT submit disks, USB flash drives, or any other form of electronic media. If your balance due is greater than your tax liability – line 15 - (line 21 + line 22) – the rebate will be used to offset your balance. If you have paid off your balance due, you will receive a rebate. Add your refundable credits found on lines
