IRS Form Schedule SE - Self-Employment Tax
Schedule SE is the IRS attachment used to calculate self‑employment tax on net earnings from self‑employment. File it with your individual income tax return (Form 1040) when you have self‑employment income.
Risk Radar
Scan points- 1A missing or miscalculated Schedule SE can trigger a penalty for underpaid self‑employment tax.
- 2Using the wrong net profit figure (e.g., forgetting Schedule F income)
- 3Failing to apply the 92.35% reduction
- 4Omitting Schedule SE entirely when required
- 5Mis‑keying the 15.3% rate
Plain English
If you earned money as a freelancer, independent contractor, or from a business you own, Schedule SE tells the IRS how much Social Security and Medicare tax you owe. It’s added to your regular tax return and shows the extra tax you must pay because you’re not an employee.
Submission Date
- Filing date: Attach Schedule SE to your Form 1040 when you file the annual return, typically by April 15 of the following year.
- Preparation window: collect IDs, supporting records, and signatures in advance.
- Final review: verify names, dates, and required fields before submission.

Common confusion points
Self‑employment vs. employee status
Mistaking W‑2 wages for self‑employment
→ Verify source of income
92.35% factor purpose
Some think it’s a discount
→ Remember it adjusts for the employer’s share
Farm income reporting
Farmers think Schedule SE isn’t needed
→ Farm net profit still flows through Schedule SE
Multiple businesses
Users add profits from several Schedule Cs
→ Sum all net profits before applying factor
Deduction of self‑employment tax
Some try to deduct the tax twice
→ Only the employer‑equivalent portion is deductible on Schedule 1
