Important May 2026 Business Tax Deadlines to Remember

Keeping your company compliant means staying ahead of the payroll and withholding calendar. This month brings several critical tax deadlines for business owners and employers to keep on their radar. Here is a breakdown of what you need to manage for May 2026.

Crucial May 2026 Tax Deadlines

May 11 - Form 941 Quarter 1 Filing

If you made full, on-time deposits for your Social Security, Medicare, and withheld income tax for the first quarter of 2026, today is your deadline to file Form 941. Missing this window can trigger unnecessary penalties, so double-check your payroll records.

May 15 - Employer’s Monthly Deposits

If your business follows the monthly deposit rules, you must remit your Social Security, Medicare, and withheld income taxes for April 2026 by May 15. This same cutoff applies to April's nonpayroll withholding deposits.

Navigating Holidays and Disaster Extensions

When a federal deadline lands on a weekend or a legal holiday, the IRS automatically shifts it to the next official business day.

Additionally, if your operations are located in a federally declared disaster zone, you likely qualify for extended relief. Check these official resources to verify your local status:
