Amended returns typically take 8-12 weeks for the IRS to process, so you should wait at least 8 weeks before checking on the status of your tax refund. If it has been over 12 weeks since you filed your amendment and you have not received your refund, you should call the IRS at 1-800-829-1040 and speak to a customer service representative.
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.
