The primary reason the state of Wisconsin rejects forms is that the incorrect Tax ID was entered in the State Withholding section. Before submitting your forms to the state of Wisconsin, make sure you have the right 15-digit withholding tax number. This number always starts with 036.
The Wisconsin Department of Revenue provides a handy lookup service in case you've misplaced your withholding tax number.

Forms rejected by the state cannot be corrected in Tax Forms Helper at this time. If your form was rejected, file paper forms with the state.
