Manufacturing forms moving to MTA for 2023 filing season – week of January 9

January 4, 2023

The Wisconsin Department of Revenue is making enhancements and upgrades to our manufacturing filing. All manufacturing returns (M-Forms) are moving from MAS into My Tax Account (MTA) for the 2023 filing season.

This improved filing system is live next week and is a one-stop shop for account management, form filing, and bill payment.
