Where will I find the addresses? Wisconsin resident.
For the federal tax returns go to this IRS website and select your state (with or without a payment) for a Form 1040 - https://www.irs.gov/filing/where-to-file-paper-tax-returns-with-or-without-a-payment
For the Wisconsin state tax returns go to this website for the mailing addresses - https://www.revenue.wi.gov/Pages/FAQS/pcs-mail.aspx
For each tax year use a separate envelope for both federal and state tax returns.
