We encourage Montana employers to do their UI tax business on line at uieservices.mt.gov. This service provides employers or their authorized representative the ability to register for a Montana UI account, update their UI account information (such as address, phone number, etc.), file their UI quarterly reports and wages, make payment by ACH debit, access most correspondence and communicate with us electronically (and more) within a secure environment. Employers may also chose to discontinue receiving paper forms and correspondence and instead, receive email notifications to log into their UI eServices account to file, pay, read and/or print communications from us. Employers who prefer paper or are unable to do their business on-line will continue to receive paper quarterly report forms, payment vouchers, rate notices and other information by mail. The most commonly used Montana forms, instructions and publications (including our Employer Handbook) are available here for you to download. All forms are in Adobe Acrobat PDF format. You will need Adobe Acrobat Reader to view and print these forms. If you do not already have Adobe Acrobat Reader installed on your computer, you may download the software for free.
