Self-Employment Tax 101: A Guide for Freelancers & Contractors
Understanding the 15.3% self-employment tax,how to calculate it,and tips for managing quarterly estimated payments.
The Hidden Cost of Freelancing
One of the biggest shocks for new freelancers is the Self-Employment (SE) Tax. While traditional employees have their Social Security and Medicare taxes split with their employer, freelancers are responsible for both halves.
What is the SE Tax Rate?
Currently, the self-employment tax rate is 15.3%. This is composed of:
- 12.4% for Social Security
- 2.9% for Medicare
This is applied to your net earnings from self-employment. Generally, only 92.35% of your net earnings are subject to the tax.
Quarterly Estimated Payments
Unlike a W-2 job where taxes are withheld from every paycheck, you are responsible for paying your own taxes throughout the year. If you expect to owe more than $1,000 in taxes, the IRS requires you to make Quarterly Estimated Payments.
Failing to pay these on time (April, June, September, and January) can result in underpayment penalties.
Deductions: Your Best Friend
You only pay tax on your net profit, not your total revenue. Make sure to track all business-related expenses, including:
- Home office equipment
- Software subscriptions
- Marketing costs
- Professional services (Accounting, Legal)
