The Wisconsin Identity Protection PIN is a number issued by the Wisconsin Department of Revenue for you to use on your Wisconsin state tax return and Homestead credit claims. This personal identification number is used to prevent unauthorized individuals from filing a WI state return using your information.
Note: The Wisconsin Identity Protection PIN is different from the IRS Identity Protection PIN. Your state-issued IP PIN cannot be used on your federal return.
Do I need a Wisconsin Identity Protection PIN?
Using a Wisconsin Identity Protection PIN is optional, but it adds an extra layer of security to your state tax return. You and your spouse can request one if you've filed a Wisconsin return or homestead credit claim within the past three years.
If you requested a Wisconsin Identity Protection PIN, you must include it on your Wisconsin individual income tax return. Failure to do so may result in your return being rejected or your refund being delayed.
How the Wisconsin IP PIN Works
Your Wisconsin Identity Protection PIN is specific to the calendar year in which it is issued.
It must be used on any Wisconsin individual income tax returns or homestead credit claims for tax years 2021 and later that are filed during that calendar year.
Example:
If you request a PIN in 2025 and file returns for 2024, 2023, and 2022 during that year, use the PIN on all three returns.
Does my dependent need a Wisconsin IP PIN?
A Wisconsin Identity Protection PIN cannot be issued to a dependent that is not filing their own state tax return.
