Understanding Self-Employment Tax
As a freelancer, you're both employer AND employee. This means you pay both halvesof Social Security and Medicare taxes—the 15.3% self-employment tax that W-2 employees split with their employer.
💡 The 15.3% Breakdown
Social Security: 12.4% (on first $168,600 in 2025)
Medicare: 2.9% (on all income)
Additional Medicare: 0.9% (on income above $200k single/$250k married)
Note: SE tax is calculated on 92.35% of net income (you get a small break).
Quarterly Estimated Tax Payments
Unlike W-2 employees who have taxes withheld each paycheck, freelancers must pay taxes quarterly. Miss these and you'll face underpayment penalties.
| Quarter | Income Period | Due Date |
|---|---|---|
| Q1 | Jan 1 - Mar 31 | April 15 |
| Q2 | Apr 1 - May 31 | June 15 |
| Q3 | Jun 1 - Aug 31 | September 15 |
| Q4 | Sep 1 - Dec 31 | January 15 (next year) |
Safe harbor rule: Pay at least 100% of last year's tax liability (or 90% of this year's) to avoid penalties.
Common Freelancer Tax Deductions

Frequently Asked Questions
How much should I set aside for taxes?
A safe rule is 25-30% of net income for most freelancers. Higher earners (above ~$100k) should set aside 30-35%. Open a separate savings account and transfer this amount with each payment received.
What's the QBI deduction?
The Qualified Business Income (QBI) deduction lets you deduct up to 20% of your net self-employment income from taxable income. This is a significant tax break for freelancers, though high-income earners may have phase-outs.
Should I form an LLC or S-Corp?
An LLC provides liability protection but no tax benefit (still pay SE tax). AnS-Corp election can save SE taxes at ~$60k+ net income by splitting income into salary (subject to SE tax) and distributions (not subject). Consult a CPA.
