Essential May 2026 Tax Deadlines for Business Owners

Staying ahead of payroll tax deadlines is essential for maintaining business tax compliance and avoiding costly penalties. As we move through spring, employers must prepare for a few critical filing requirements.

Key May 2026 Deadlines

May 11: Form 941 Extended Filing

Employers who deposited all first-quarter 2026 Medicare, Social Security, and withheld income taxes accurately and on time have an extended deadline to file Form 941. If you fell behind on your quarter-one deposits, this extension does not apply to your business.
