I am a resident of Wisconsin working in Minnesota. How does the ending of the reciprocity agreement affect me?
Beginning January 1, 2010, your Minnesota employer will withhold Minnesota income taxes from personal service income, such as salaries, wages, commissions and fees.
Your Minnesota employer will use the federal Form W-4 or the Minnesota W-4MN to determine the amount of Minnesota income tax to be withheld from your wages. Contact your Minnesota employer if you have questions about Form W-4 or Form W-4MN.
Will my employer withhold Wisconsin tax from my wages?
No, Wisconsin income taxes will not be withheld from that income. See
special withholding arrangement announced by the Secretary of Revenue.
Will I need to make Wisconsin estimated tax payments?
Every situation is different but generally, the credit for income tax paid to Minnesota will offset the Wisconsin income tax on the Minnesota wages so estimated tax payments will not be required. However, if you have income not subject to withholding such as interest, dividends, capital gains, unemployment compensation, etc., you may need to make
estimated tax payments.
What do I need to do?
- File a 2023 Minnesota income tax return in 2024 as a nonresident. All personal service income earned in Minnesota will be reported to Minnesota.
- File a 2023 Wisconsin income tax return (Form 1) in 2024. You will report all income received, including wages earned in Minnesota, on your Wisconsin return. Wisconsin will allow a credit for the net income tax paid to Minnesota on income that is taxed by both Wisconsin and Minnesota.
