A mild snowstorm. A winter storm is an event in which varieties of precipitation are formed that only occur at low temperatures, such as snow or sleet, or a rainstorm where ground temperatures are low enough to allow ice to form (i.e. freezing rain).
Federal amendments are generally due within three years from the date the return is originally due. The tax year and due date are a little confusing to understand, so the easiest way to think of due dates is to add one year to the tax year you want to amend.
How long does IRS have to pay a refund on an amended return? I have contacted the National Tax Payers Advocate and received different answers. The problem is that it has been five months now since I filed an amended return for a refund and we have had no communication from the IRS. It just sits in examination for review since April, 22, 2008 with no activity or release for payment.
