(WASHINGTON) — Heading into the new year, Senate Democrats are raising concerns about the Internal Revenue Service’s ability to handle the upcoming tax filing season, amid changes in leadership and to the workforce in the first year of the Trump administration.
In a letter to Treasury Secretary and acting IRS Commissioner Scott Bessent obtained first by ABC News, the group of 17 senators, led by Elizabeth Warren of Massachusetts, and Angus King, a Maine independent who caucuses with Democrats, wrote that they have “serious concerns” the IRS is “not prepared” for the next tax season, and that taxpayers “may face delays and difficulties in filing returns and receiving refunds.”
The Trump administration has conducted large-scale layoffs and voluntary buyouts — some of which have been reversed — at the IRS, which is also responsible this year for implementing new changes to the tax code following the passage of Republicans’ major tax and domestic policy bill.
Bessent has served as acting IRS commissioner since August after President Donald Trump removed Billy Long, a former GOP congressman, from the role two months after he was confirmed by the Senate and nominated Long to become the U.S. ambassador to Iceland.
Bessent became the seventh official to lead the agency in 2025, following Long and a string of other senior officials.
The law made permanent the 2017 GOP tax cuts, while boosting funding for border security and the Defense Department, scaling back some social safety net programs, and limiting taxes on tips and overtime for some workers.
In a statement to ABC News, Warren accused the Trump administration of enacting changes that will benefit wealthy Americans and make it harder for other Americans seeking help from the agency.
“Donald Trump’s endless attacks on the IRS are good news for his billionaire buddies and giant tax prep companies, but bad news for Americans getting ready for filing season. Americans rely on the IRS to file their taxes and get their tax refunds quickly and easily, and I’m pressing for answers,” she wrote.
The Democrats also cited a September report from the Treasury Department Inspector General for Tax Administration on the previous filing season.
While the watchdog called the 2025 filing season “successful” and found that the agency processed more tax returns compared to the same time period in the previous year, it also found that the Trump administration’s workforce reductions “had no significant impact” on the 2025 filing season — but that they could “impact key processing programs and customer service going forward.”
According to the inspector general’s office, the staffing losses on customer service and anti-fraud teams could lead to the agency processing fewer returns, assisting fewer taxpayers, and failing to prevent $360 million in fraudulent refunds from being paid out.
The Treasury Department did not immediately respond to questions from ABC News about the inspector general’s report and the concerns raised by Democrats.
