IRS confirms 2026 tax filing start date — when you can file and what to know

IRS Confirms 2026 Tax Filing Start Date: The IRS will officially begin accepting 2025 tax returns on January 26, 2026. This early start follows the "One Big Beautiful Bill," introducing historic relief for millions. Taxpayers can access the IRS Free File program starting January 9. With over 160 million returns expected, filing electronically is essential. New "no tax" rules on tips and overtime, plus senior bonuses, could significantly boost your federal refund this year.
