Proposed IRS data sharing with immigration authorities and ICE raids have made filing risky for those who are undocumented

The Trump administration’s immigration crackdown could cause the US to potentially lose up to $479bn in lost tax revenue over the the next 10 years, with enforcement deterring undocumented workers from filing their taxes this year, according to tax experts.

Tax advisers say major changes, including proposed data sharing with immigration enforcement, have made filing taxes risky for undocumented immigrants. Tax benefits for immigrant parents have also been removed, further removing incentive to file taxes at all.

Experts believe that a drop in tax filings could cost the federal government billions of dollars in lost revenue. According to Yale’s Budget Lab, the losses could range from $147bn to $479bn over the next 10 years. At the same time, up to 2.7 million children who are US citizens or lawful permanent residents might lose access to the credit due to these policy changes.
