January 3, 2018 Adam Rivera

Wisconsin has released Publication 166, the Wisconsin Withholding Tax Guide. This publication contains withholding information for Wisconsin employers, and there are a number of changes from the previous revision:

  • The 2017 Wisconsin Act 59 made several changes to W-2 and information return reporting requirements, so now beginning with payments made in 2017:
    • An employer or payer required to file 10 or more W-2s or 10 or more of any one type of information return with the department must file their returns electronically
      • The previous threshold was 50 or more
    • All W-2s and information returns required to be filed with the Wisconsin DOR are due by January 31.
      • The prior due dates for statements of nonwage payments and rent and royalties were February 28 and March 15
    • Now only a 30-day extension is available for filing these returns
      • Previously, a 60-day extension period was available for rent and royalty statements and nonwage statements
