Does Wisconsin have a form for child tax credit?

No, there is not a separate child tax credit form in Wisconsin.

There is not a Wisconsin Child Tax Credit.

However, there are other tax credits that Wisconsin makes available for their tax payers.

There is a Wisconsin Earned Income Credit and a Wisconsin Homestead Credit.

I've included a link from Wisconsin regarding these tax credits that may be helpful.
