If your only income was from social security benefits then you are not required to file a federal return and therefore have no taxable income to report. 

Since Wisconsin does not tax social security benefits, you are not required to file a Wisconsin state return either. You can still complete schedule H-EZ and mail it in to claim your homestead credit. Please click the link below to print schedule H-EZ.

Then, follow the directions in the Wisconsin link below to complete and assemble Schedule H-EZ.
