Status of Processing Form 1040-X, Amended Individual Tax Return: As of November 13, 2021, we had 2.7 million unprocessed Forms 1040-X. We are processing these returns in the order received and working hard to get through the inventory. The current timeframe can be more than 20 weeks instead of up to 16. Please don't file a second tax return or contact the IRS about the status of your amended return.
