IRS Tax Amendment Status
The Internal Revenue Service informs taxpayers to expect the process of a tax return amended will be within 16 weeks.
While this is true for the majority of amended returns, a portion takes longer to process or faces problems not well explained by the IRS.
The IRS does not disclose to taxpayers that if their amended returns are selected for audit, processing will likely take several more months and sometimes the IRS will simply stop processing them. In these situations, the Where’s My Amended Return tool, is of little help because it has only three statuses (received, adjusted, or completed) and does not explain where an amended return is in the processing pipeline or estimate when processing will be complete.
