Next month, the Wisconsin Department of Revenue is making enhancements and upgrades to our manufacturing filing. All manufacturing forms (M-Forms) are moving from Manufacturing Assessment System (MAS) into My Tax Account (MTA) for the 2023 filing season. This improved filing system rolls out the week of January 9 and is a one-stop shop for account management, form filing, and bill payment.
Familiar – the changeover to MTA consolidates tax filing to a system most businesses already use to file and pay business taxes
Ease of use – MTA allows authorized users to complete many tasks, such as:
- Request extensions
- File returns
- Make penalty payments
- Modify and manage user access
Secure – no downloading forms using third-party software
You or your representative must be registered as a user in MTA to e-file your manufacturing forms. If you or your representative:
- Already have an MTA login – you don't need to do anything at this time
- Don't have an MTA login – do the following to create a username and password
- Go to
MTA – click "New? Create new username"
- Complete new registration steps 1-3 (Logon Information, Customer Information, Active Business) and click submit; you'll finish step 4 in mid-January 2023
M-Forms – will be live in MTA on January 9, 2023
Greeting letter – you'll be receiving a letter with a Letter ID, which you need to access your accounts
Transition details – we will continue to keep you informed throughout this process
MAS – you can no longer file in MAS; however, your historical filings will still be available for review
