May 2026 Employer Tax Deadlines: Keep Your Payroll on Time

At our Billings firm, we believe business stability rests on a "three-legged stool": accurate books, optimized taxes, and on-time payroll. For subcontractors, real estate professionals, and service businesses across Montana and surrounding states, keeping that payroll leg sturdy means tracking important deadlines. Let's look at the critical employer tax due dates for May 2026.

Key May 2026 Payroll Tax Deadlines

May 11 – Form 941 Filing

Employers must file Form 941 for the first quarter of 2026 by this date, but this specific deadline only applies if you already deposited your tax for the quarter in full and on time.

May 15 – Monthly Employer Deposits

If your business operates under the monthly deposit rules, your April 2026 deposits for Medicare, Social Security, and withheld income tax are due today. This also serves as the due date for nonpayroll withholding deposits.

Holidays and Disaster Extensions

Whenever a tax deadline lands on a weekend or legal holiday, it automatically rolls over to the next business day. Additionally, if your region experiences extreme weather, filing dates may shift. Check current geographic extensions via the following resources:
