Self-Employed vs W-2: What You Actually Pay More
As a W-2 employee, your employer pays half (7.65%) of your FICA taxes. Self-employed individuals pay both halves — 15.3% total. However, you can deduct half of SE tax before calculating income tax, and the higher deduction options (SEP-IRA up to $70k, full health insurance premium) can significantly offset this.
