Form Schedule SE is one of the forms every US small business eventually encounters. Here's everything you need to know.

What is Form Schedule SE?

Schedule SE — Self-Employment Tax

Purpose: Calculates Social Security and Medicare tax for self-employed

Filing deadline: With Form 1040

Who must file Form Schedule SE?

If you're a US-based business or self-employed individual, you likely need to file Form Schedule SE if any of these apply:

  • You meet the threshold specific to this form
  • You're in an applicable business activity or entity type

How to complete Form Schedule SE

The form can look intimidating, but the process breaks down into:

1. Collect the information (payee name, TIN, amount paid)

2. Fill out the form (paper or electronically)

3. Deliver copies (to recipient, IRS, and state if required)

4. Keep a copy for your records (7 years recommended)

Penalties for missing Form Schedule SE

Penalties scale with how late you file:

  • Up to 30 days late: $60 per form
  • 31 days to August 1: $130 per form
  • After August 1 or not at all: $330 per form
  • Intentional disregard: $660+ per form

For a business with 10 unfiled forms, that's $6,600 in penalties — easily avoided by filing on time.
