Question

Fred has been completing his own tax returns for years. The IRS has recently contacted him with questions about some of his prior returns. How many years back is he responsible for providing documentation?

Answer 1

The IRS will usually request information about the last three years when they are performing an audit, but if they find any substantial errors, then the IRS might request information about the last six years.

If the IRS determines that you made a mistake with your past tax filings, they can try to collect unpaid taxes for the last ten years.
