January 2026 Business Due Dates

January 2026 brings key tax deadlines for businesses, employers, farmers, and fishermen. A little planning now can help keep compliance on track and penalties off your radar.

January 15 - Employer’s Monthly Deposit Due -

If you are an employer and the monthly deposit rules apply, January 15 is the due date for you to make your deposit of Social Security, Medicare, and withheld income tax for December 2025. This is also the due date for the nonpayroll withholding deposit for December 2025 if the monthly deposit rule applies. Employment tax deposits must be made electronically (no paper coupons), except employers with a deposit liability under $2,500 for a return period may remit payments quarterly or annually with the return.

January 15 - Farmers and Fishermen -

Pay your estimated tax for 2025 using Form 1040-ES. You have until April 15 to file your 2025 income tax return (Form 1040 or Form 1040-SR). If you don't pay your estimated tax by January 16 15, you must file your 2025 return and pay any tax due by March 2, 2026, to avoid an estimated tax penalty.

Weekends & Holidays:

If a due date falls on a Saturday, Sunday or legal holiday, the due date is automatically extended until the next business day that is not itself a legal holiday.
