Critical Tax Deadlines for Businesses in August 2025

Staying on top of essential IRS deadlines is crucial for maintaining compliance and avoiding penalties. This guide covers key due dates for businesses in August 2025, focusing on payroll taxes and filings.

August 11 - Quarterly Payroll Tax Filing

Ensure timely submission of Form 941 for Q2 2025, applicable only if taxes were fully paid on time. This step is vital for compliance in managing Social Security, Medicare, and federal income taxes.

August 15 - Monthly Payroll Tax Deposit

Employers must deposit July 2025's Social Security, Medicare, and withheld income tax by this date if monthly rules apply. Nonpayroll withholding for the same period must also be deposited by this deadline.

Considerations for Weekends & Holidays:

Should a deadline land on a weekend or recognized holiday, it automatically shifts to the next working day. This gives you extra time but also highlights the importance of strategic planning.

Extensions for Disaster-Affected Areas:
In designated disaster areas, the IRS often provides extensions. For updated details on disaster designations and related filing extensions, consult these resources:
