June 8 (UPI) -- The Taxpayer Inspector General reported Monday that the use of IRS taxpayer data for immigration enforcement has been inconsistent and unreliable.

The report said that the IRS provided addresses for nearly 47,000 people to U.S. Immigration and Customs Enforcement as part of a data-sharing agreement when the Trump administration ramped up its deportation efforts.

It also found that ICE did not meet the safeguarding standards for receiving confidential taxpayer information.

"Our evaluation found that, before releasing address information on individual taxpayers, the IRS developed an automated process to match ICE data to IRS records," the report reads. "However, the criteria were unable to identify and match the records accurately and consistently."
