August 11 - File Form 941 for Q2 2025

Ensure you submit Form 941 for the second quarter of 2025, provided you have made full and timely tax deposits. This form is essential for reporting withholding amounts of social security, Medicare, and income taxes.

August 15 - Monthly Payroll Tax Deposit

Employers bound by monthly deposit rules should mark August 15 as the deadline for remitting taxes including Social Security, Medicare, and withheld income tax for July 2025. Nonpayroll withholding deposits also follow this deadline under the same monthly rules.

Consideration for Weekends & Holidays

If tax due dates coincide with weekends or legal public holidays, the deadline extends to the subsequent business day. This allows for extra time to ensure compliance without incurring penalties.

Special Extensions for Disaster Areas

Businesses located in designated disaster areas might qualify for extended deadlines. For accurate details on qualifying locations and extended dates, please visit the following resources:
