Quick Answer
Schedule SE calculates self-employment tax (15.3% rate) on your freelance income. You must file it if you have $400+ in net self-employment earnings from Schedule C. Most freelancers earning over $1,538 will hit this threshold and owe at least $236 in self-employment tax.

What is Schedule SE?
Schedule SE (Self-Employment) is the IRS form that calculates your self-employment tax — essentially your Social Security and Medicare taxes as a freelancer. When you work for an employer, they pay half of these taxes (7.65%) and you pay the other half. As a freelancer, you pay both halves, totaling 15.3%.
When must you file Schedule SE?
You must file Schedule SE if your net earnings from self-employment are $400 or more. This is your Schedule C profit (gross income minus business expenses), not your total revenue.
Example: Meeting the $400 threshold
Let's say you're a freelance writer who earned $2,500 in 2026:
Since $2,200 > $400, you must file Schedule SE.
Even if you earned $1,000 but had $700 in expenses (net earnings = $300), you wouldn't need to file Schedule SE because $300 < $400.
How much will you owe?
The self-employment tax rate is 15.3% (12.4% for Social Security + 2.9% for Medicare), but it's calculated on 92.35% of your net earnings due to a deduction that simulates the employer portion.
Calculation example: $15,000 net earnings
Plus, you get to deduct half of this SE tax ($1,060) on your Form 1040, reducing your income tax.
Key factors that affect Schedule SE
What you should do
1. Track your net earnings throughout the year using our freelance dashboard
2. Make quarterly estimated payments if you expect to owe $1,000+ in total taxes
3. File Schedule SE with your tax return if net earnings exceed $400
4. Don't forget the deduction — half your SE tax reduces your adjusted gross income
Use our quarterly estimator to calculate both income tax and self-employment tax payments throughout the year.
Key takeaway: File Schedule SE if your freelance profit (after expenses) is $400+. Expect to pay 15.3% in self-employment tax, but you'll get to deduct half of it on your return.

Key Takeaway: File Schedule SE when your net freelance earnings exceed $400, and expect to pay 15.3% in self-employment tax on 92.35% of those earnings.

W-2 employees with freelance income on the side
Schedule SE for side hustlers
As a W-2 employee with side freelance income, you still need Schedule SE if your freelance profit exceeds $400. The tricky part is that your W-2 wages affect how much Social Security tax you owe on freelance income.
Example: $65,000 W-2 salary + $8,000 freelance profit
This is in addition to any income tax you owe on the $8,000.
Why side hustlers get surprised
Many side hustlers don't realize they need to make quarterly estimated tax payments. If your total tax owed (including SE tax) minus withholding from your W-2 job exceeds $1,000, you should make quarterly payments to avoid penalties.
Key takeaway: Side hustlers with $400+ in freelance profit must file Schedule SE, even though your W-2 job already covers some Social Security taxes.
Key Takeaway: Side hustlers must file Schedule SE for freelance profits over $400, in addition to W-2 withholding — plan for quarterly payments if you'll owe $1,000+ total.

Experienced freelancers with substantial self-employment income
Schedule SE for high earners
As a full-time freelancer, Schedule SE becomes more complex once your earnings approach the Social Security wage base of $176,100 (2026 limit).
The Social Security cap matters
If your net self-employment earnings exceed $176,100, you'll hit the Social Security tax cap:
Example: $200,000 net freelance earnings
Plus, you deduct half ($13,596) on Form 1040.
Quarterly payment strategy
With high SE tax liability, quarterly estimated payments are essential. Consider paying 110% of last year's total tax (safe harbor rule) to avoid penalties, especially if your income is growing.
Key takeaway: High-earning freelancers face SE tax caps and additional Medicare taxes — careful quarterly planning prevents large year-end tax bills.
Key Takeaway: Full-time freelancers earning over $176,100 hit Social Security tax caps but face unlimited Medicare tax, requiring strategic quarterly payment planning.
