The Nebraska Certificate of Mailing Objection And Notice of Hearing is a document used in the state of Nebraska to provide a record that an objection to a tax assessment has been mailed to the Nebraska Department of Revenue (FOR). The certificate must be filed with the FOR within 30 days of the mailing of the objection. It is important to note that the filing of the certificate does not extend the time for filing a formal appeal in the district court. There are two types of Nebraska Certificate of Mailing Objection And Notice of Hearing: 1. The Certificate of Mailing Objection: This is used to document the date that an objection to a tax assessment was mailed to the FOR. 2. The Notice of Hearing: This is used to document the date that a notice of hearing was mailed to the FOR. The notice of hearing must be filed at least 30 days prior to the hearing date.
