The key difference: self-employment tax
As a W2 employee, you pay 7.65% in payroll taxes (Social Security + Medicare). Your employer pays another 7.65%.
As a 1099 contractor, you pay the full 15.3% yourself — but you can deduct half of it from your income.
On a $100,000 income, the extra SE tax costs you about $5,650/year as 1099 vs W2. To break even, your 1099 rate needs to be about 6% higher than your W2 salary.
