The IRS has faced criticism for its ineffective oversight of Act 22, a tax incentive program in Puerto Rico aimed at attracting wealthy investors. Despite a three-year campaign to audit and regulate the program, few audits have been conducted and no back taxes have been collected. Whistleblowers and critics argue that the IRS lacks the necessary resources and authority to enforce the tax laws effectively. The Senate Finance Committee is now investigating the IRS's handling of Act 22, amid growing concerns about the displacement crisis of local residents and the failure to close tax loopholes that can cut wealthy Americans' tax bills to zero. Calls for transparency from the IRS have intensified.
