August 11 - Social Security, Medicare, and Withheld Income Tax

By August 11, ensure you file Form 941 for the second quarter of 2025. This requirement applies if your tax deductions for the quarter have been fully and punctually paid. Compliance with these criteria helps businesses avoid unnecessary complications and fines.

August 15 - Social Security, Medicare, and Withheld Income Tax

Employers abiding by the monthly deposit rules must make deposits for Social Security, Medicare, and withheld income tax for July 2025 by this date. This deposit deadline also applies to nonpayroll withholdings for July if monthly rules apply. Adhering to these deadlines improves cash flow management and strengthens fiscal discipline.

Weekends & Holidays:

Business deadlines are generally extended to the next working day if they fall on a weekend or legal holiday. Understanding these small nuances can prevent oversight and maintain seamless operation.

Disaster Area Extensions:
In cases where a region has been officially recognized as a disaster area, filing deadlines will be adjusted. For updates on disaster designations and new filing timelines, visit:
