Understanding Self-Employment Tax
Self-employed workers pay both employer and employee portions of Social Security and Medicare taxes.
Tax rate breakdown: Self-employment tax: 15.3% total
- Social Security: 12.4%
- Medicare: 2.9%
Regular employees pay 7.65% while employers pay matching 7.65%. Freelancers pay both portions.
Income threshold: Self-employment tax applies to net earnings over $400 annually. Even small side hustles require tax payment and filing.
Deductible portion: You can deduct half of self-employment tax from income tax. This reduces overall tax burden slightly.
Example: $50,000 net freelance income
- Self-employment tax: $7,065
- Deductible amount: $3,532
Quarterly Estimated Tax Payments
Freelancers must pay taxes quarterly instead of waiting until April.

- Q2: June 15 (April-May income)
- Q3: September 15 (June-August income)
- Q4: January 15 (September-December income)
Calculating payments: Estimate annual income and taxes owed. Divide by four paying each quarter. Use previous year's tax as baseline adjusting for income changes.
Safe harbor rule: Pay 100% of prior year's tax (110% if income over $150,000) avoiding penalties even if current year income higher.
Payment methods: IRS Direct Pay (free), Electronic Federal Tax Payment System, Credit card (2% fee), Mail check with Form 1040-ES.
