Federal Employer Deadline Calendar 2027: Payroll Tax, OSHA and Form 5500

Missing one payroll tax date can cost real money. This puts every federal date for 2027 on one page. Print it, tick what applies to you, and import the dates into your calendar with reminders.

What you get

• Year at a glance: one printable page with every due date marked.
• Every date with its source: Forms 941, 940, 945, W-2/W-3, 1099-NEC, OSHA 300A posting and electronic submission, Form 5500, plus monthly deposit dates.
• Weekend and holiday moves done: Jan. 31, Jul. 31 and Oct. 31 fall on weekends in 2027, so the calendar shows Feb. 1, Aug. 2 and Nov. 1.
• Excel tracker: Yes, No or Check on each row, an owner, reminder days, status and days left.
• Calendar file (.ics): works with Google Calendar, Outlook and Apple Calendar, with a 7 day reminder on each date.
• Plain rules and a filled example for a fictional company.

How it works

1. Print page 2.
2. Open the Excel file and mark what applies.
3. Import the calendar file.

Requirements

A PDF reader. Excel or Google Sheets for the tracker. Any calendar app for the .ics file.
