Key Tax Deadlines for January 2026: A Business Guide

As January 2026 approaches, businesses, employers, farmers, and fishermen need to stay mindful of critical tax deadlines. Smart planning can help maintain compliance and keep penalties at bay.Image 1

January 15 - Employer’s Monthly Deposit Due -

If you are an employer subject to monthly deposit rules, mark January 15 on your calendar as the deadline to deposit Social Security, Medicare, and withheld income taxes for December 2025. This date also applies to nonpayroll withholdings if the monthly deposit rule affects you. Remember, employment tax deposits must be made electronically unless your deposit liability is under $2,500 for the return period, allowing for quarterly or annual remittances with the return.

January 15 - Farmers and Fishermen -

Use Form 1040-ES to pay your estimated tax for 2025. You have until April 15 to file your 2025 income tax return using Form 1040 or Form 1040-SR. Should you opt not to remit your estimated tax by January 15, make sure to file your 2025 return and pay any remaining taxes by March 2, 2026, to avoid penalties.Image 2

Weekends & Holidays:

Take into account that if a due date falls on a Saturday, Sunday, or legal holiday, the deadline automatically extends to the next business day that is not a holiday.

Geographical areas designated as disaster zones receive filing extensions. To confirm if your area is affected and learn about extension dates, check these sites:
