The IRS right now isn't the same agency it was at the start of this year.

That's because about 20% of IRS workers have signaled they want to leave or have been fired. The ripple effects of this exodus could go far, not just for the IRS itself, but for businesses and individual taxpayers trying to file their returns.

Roughly half of the 30 people at the top of the IRS organizational chart have left, many because of Trump administration decisions that stretch boundaries of the law. Those departures in particular erode an important layer of defense to the IRS's most important missions: taxpayer data security and a fair tax system, former and current agency officials said.

Most recently, two executives brought on to help the IRS build up its enforcement and reporting of digital assets left and were replaced by longtime IRS official Trish Turner.

The leadership departures, combined with the broader cuts across different levels of the agency, make it harder for the IRS to collect revenue for the government and provide help to taxpayers. The IRS plans to lean more heavily on technology to make up for the lost workers.

In this episode of Talking Tax, Bloomberg Tax reporters Erin Slowey and Erin Schilling discuss who's replacing executives who have left, the impacts of the high turnover, and what happens when workers who want to leave can't.
