If you made a mistake on your annual MinnesotaCare Tax return you can file an amended return to correct any errors.
You must file your amended return within 3 ½ years from the due date of the original return. All amended returns are subject to a MinnesotaCare Tax audit.
Make sure to keep all supporting documentation from your original and/or amended return. That documentation must be available upon the department’s request.
