The U.S. House has passed a series of measures aimed at compelling Washington D.C. to align its tax code with federal tax cuts, including those from the Trump administration, which could result in a loss of $600 million in revenue for the city. This political struggle occurs as D.C. officials warn of chaos during the tax filing season, with potential delays and disruptions affecting over 300,000 taxpayers. Opposition from local leaders and advocacy groups highlights the risks of imposing these changes, particularly regarding child tax credits and benefits for tipped and overtime workers. As the Senate prepares to address these tax changes, concerns over the implications for families and businesses in D.C. grow, emphasizing the contentious nature of congressional interference in local tax policies.
