A group of US lawmakers is asking tax authorities to accelerate an investigation into rich Americans seeking lucrative tax breaks in Puerto Rico.

Twelve Democratic members of the House of Representatives asked the Internal Revenue Service on Friday to expedite a congressional request for information about efforts to root out people allegedly abusing Puerto Rico’s tax benefits. In July, the IRS said it was investigating about 100 wealthy individuals and might pursue criminal charges after announcing an audit of the benefits in 2021.
