Schedule SE: Self-Employment Tax for H-1B Visa Holders
If you or your H-4 EAD spouse earn self-employment income through freelancing, consulting, or a side business, Schedule SE calculates the Social Security and Medicare taxes you owe on that income. This guide explains when H-1B households need Schedule SE and how the 15.3% self-employment tax works.
What Is Schedule SE?
Schedule SE (Self-Employment Tax) computes Social Security and Medicare tax for individuals who work for themselves. When you receive a W-2, your employer withholds 7.65% for FICA and pays a matching 7.65%. When you are self-employed, you pay both halves — a combined 15.3% on net self-employment earnings.
The tax has two components: 12.4% for Social Security (on the first $168,600 of combined wages and SE income for TY2025) and 2.9% for Medicare (no cap). If your combined income exceeds $200,000 ($250,000 MFJ), an additional 0.9% Medicare surtax applies under IRC Section 1401(b)(2).
Who Needs to File Schedule SE?
- Anyone with net self-employment earnings of $400 or more during the tax year.
- H-4 EAD spouses who freelance, consult, or operate a business.
- H-1B holders with Schedule C side income (subject to visa employment restrictions — consult an immigration attorney).
- Partners receiving Schedule K-1 income from a partnership where they are a general partner or active LLC member.

How Schedule SE Is Calculated
- Start with net profit from Schedule C (line 31) or net self-employment income from K-1.
- Multiply by 92.35% (0.9235) to get the tax base. This adjustment mirrors the employer-share deduction that W-2 employees effectively receive.
- Apply the 15.3% rate (12.4% Social Security + 2.9% Medicare) to the adjusted amount.
- If combined wages and SE income exceed the Social Security wage base ($168,600 for 2025), the 12.4% portion stops and only the 2.9% Medicare portion continues.
- Deduct half of the SE tax as an above-the-line deduction on Schedule 1, line 15. This reduces your AGI.
Example: H-4 EAD Freelancer
| Schedule C net profit | $45,000 |
| x 92.35% | $41,558 |
| SE tax (15.3%) | $6,358 |
| Deductible half (Schedule 1) | $3,179 |
Key Lines on Schedule SE
- Line 2: Net farm profit or loss (rarely applicable for H-1B households).
- Line 3: Net profit from Schedule C (your primary self-employment income source).
- Line 4a-4b: 92.35% adjustment.
- Line 6: Social Security tax component.
- Line 10: Medicare tax component.
- Line 12: Total self-employment tax, which transfers to Schedule 2, line 4.
- Line 13: Deductible half, which transfers to Schedule 1, line 15.
Interaction with W-2 Wages
If you have both W-2 wages and self-employment income, your employer already withheld Social Security tax on your wages. The Social Security portion of SE tax only applies to the gap between your W-2 wages and the $168,600 wage base. If your W-2 wages already exceed $168,600, you owe zero Social Security tax on your SE income — but you still owe the 2.9% Medicare portion.
