If a notice of assessment or denial of refund has been issued to the taxpayer by the Department and the taxpayer files an appeal, the records for the periods covered by the notice of the assessment or denial of refund must be preserved and retained until the issue has been resolved. 2. Maintaining records that will be needed to complete a future return, such as when the records have information related to a net operating loss or net casualty loss.3. A return has been subject to a federal audit. 35 Miss. Code. R. 1-02-107
