​​The Internal Revenue Service (IRS) is eliminating Forms 1040A and 1040EZ for tax year 2018. As a result, Wisconsin is eliminating Forms 1A and WI-Z for tax year 2018 to correspond with the federal form change. Most taxpayers will see no difference in preparing their Wisconsin tax returns, as approximately 85% of Wisconsin taxpayers file their income tax returns electronically using Wisconsin e-file or other approved software vendors.

In 2019, Wisconsin residents will file their 2018 individual income tax return using Form 1. Wisconsin nonresidents and part-year residents continue to file using Form 1NPR.

The IRS is also redesigning Form 1040. See their website for the draft 2018 Form 1040.
