It’s worth noting that the existence of an audit, according to the IRS, does not preclude the release of tax returns. In fact, it actually makes the release of returns less risky. The primary issue with making your tax returns public is triggering an audit. Trump doesn’t have to be worried about that.
But there is a bigger problem with the Trump campaign’s argument that all his returns are under audit: It’s not true.
The truth is disclosed in a letter from his accountants that was published to the Trump campaign website in March. It reveals that Trump’s returns from 2008 and prior are not under audit and have been “administratively closed” by the IRS.
