If a Wisconsin individual income tax return is filed electronically using the Modernized eFile (MeF) platform, an amended return for the same taxpayer and year cannot be filed electronically for at least 24 hours. An amended return submitted within 24 hours of the original return will reject. If you need to amend a return shortly after submitting the original return, wait at least 24 hours after submitting the original return to electronically file the amended return. Remember to indicate in the space provided that the return is amended.
