SOUTH MILWAUKEE SCHOOL DISTRICT CODE

CJHINCE1 — Sun, 29 Mar 2026 17:43:47 GMT

I am trying to do my state taxes for Wisconsin, but no matter what I enter for a school district code I get an error stating that it's an invalid code. I live in South Milwaukee and am using the correct code.

The code for the South Milwaukee School District is 5439.

You can try a number of options to see if these fix an "invalid code" error.

1). Clear the "error" field.

Delete the code entirely and leave the box blank.
Go to the next screen (just ignore any program "objections").
Go back to the school district screen and try typing 5439 again.

2). Make sure you selected "City" for South Milwaukee. If you accidentally selected "Town" or "Village," the software won't recognize "5439" as a valid match for that municipality type.

3). For TurboTax Online: Clear your browser cache and cookies (the software should pull the most recent validation rules from the server).
