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

File Form 941 for the second quarter of 2025. This deadline is applicable if you have paid your due taxes for the quarter in full and on time.

August 15 - Monthly Payroll Tax Deposits

Employers must adhere to the August 15 deadline to deposit Social Security, Medicare, and withheld income taxes for July 2025 if subject to monthly deposit rules. Additionally, nonpayroll withholdings for July 2025 should be deposited by this date under the same rule.

Considerations for Weekends & Holidays

Should any due date fall on a Saturday, Sunday, or legal holiday, it is automatically shifted to the next business day that is not a holiday.

If your business is located in a disaster-designated area, additional time to meet IRS deadlines may be granted. Stay updated on the status of geographic areas by visiting the following resources:
