IRS tax filing season starts Jan. 26

Jan. 26 marks the official start date of the 2026 tax filing season, when the IRS will begin accepting and processing 2025 tax returns. April 15 is the filing deadline to avoid penalties and interest.

Tax season is the annual period when taxpayers prepare and submit their income tax returns for the previous calendar year to the IRS and most U.S. citizens and permanent residents need to file a tax return if they make more than a certain amount of money for the year.

Tax experts, including the IRS’ independent watchdog, have warned that this year’s filing season could be hampered by the loss of tens of thousands of tax collection workers who left the agency through planned layoffs and buyouts spurred by Elon Musk’s Department of Government Efficiency.

IRS Chief Executive Officer Frank Bisignano, who was named to the new role in October, said “the IRS workforce remains vigilant and dedicated to their mission to serve the American taxpaying public. At the same time, IRS information systems have been updated to incorporate the new tax laws and are ready to efficiently and effectively process taxpayer returns during the filing season.”

The IRS will also be responsible for implementing major provisions of Republicans’ tax and spending package signed into law last summer. Several provisions in the law retroactively affect the 2025 tax year, likely leading to more questions from taxpayers and requiring the IRS to update tax forms.

The average refund amount was $3,167, according to IRS data. Bessent has said on several occasions that the effects of Republican tax law will result in bigger tax refunds in 2026.
