The IRS's fiscal year 2025 Data Book records USD 5.3 trillion in revenue collected across 271.4 million processed returns, as the agency rolls out new tax benefits under the Working Families Tax Cuts Act and accelerates a shift toward digital-first service delivery.
The US Internal Revenue Service (IRS) issued the 2025 Data Book on 5 June 2026, detailing the agency’s activities during fiscal year 2025. The report provides a statistical overview of the agency’s operations and the work employees performed to meet statutory responsibilities.
“Fiscal Year 2025 was a pivotal year, as we began the process of implementing tax relief for hardworking Americans enacted as part of the Working Families Tax Cuts Act,” said IRS CEO Frank J. Bisignano. “The numbers in the Data Book tell the story of an organisation that serves as a key partner in the administration’s mission.”
During the 2026 filing season, roughly 45% of individual tax returns filed claimed one or more of the new tax benefits from the WFTC: no tax on tips, no tax on overtime, no tax on car loan interest, and/or the enhanced tax deduction for seniors. The average refund on a return claiming one of these deductions was over USD 3,200, as of 27 May.
To enhance compliance, safeguard privacy, and provide the best service and experience for taxpayers, the IRS is pivoting to modern technology. Online tools, including the IRS Online Account for individuals and businesses, have been upgraded to expand access and add new features. Expanded technology and advanced analytics allow the IRS to identify high-risk areas of non-compliance and tax fraud with greater accuracy and efficiency. The CEO also highlights efforts to transform the IRS into a digital-first agency and reduce paper processing at the service through the “zero paper” initiative.
