Freelance Tax Calculator (Self-Employment Tax)
Estimate your 15.3% US Self-Employment tax liability and net profit.
Understanding Self-Employment Tax
When you work as a freelancer, independent contractor, or small business owner, the IRS considers you both the employer and the employee. This means you are responsible for the full 15.3% Social Security and Medicare taxes, commonly known as the Self-Employment (SE) tax.
Traditional W-2 employees only see 7.65% deducted from their paychecks because their employers pay the other 7.65%. As a freelancer, you cover both halves. This calculator specifically targets the SE tax portion of your tax burden.
How the Calculation Works
The IRS doesn't tax your entire gross revenue. Instead, the calculation follows these steps:
- Calculate Net Profit: Subtract your legitimate business expenses (software, equipment, office space) from your gross income.
- Apply the 92.35% Multiplier: The SE tax is calculated on 92.35% of your net earnings. This accounts for the deduction of the employer-equivalent portion of self-employment tax.
- Apply the 15.3% Rate: This consists of 12.4% for Social Security (up to the annual wage limit) and 2.9% for Medicare.
If you earn $100,000 in revenue and have $20,000 in expenses, your net profit is $80,000.
1. Taxable Basis: $80,000 × 0.9235 = $73,880
2. SE Tax: $73,880 × 0.153 = $11,303.64
3. Estimated Take-Home: $68,696.36 (before standard federal/state income taxes).
How to Lower Your Freelance Tax Bill
The most effective way to lower your tax liability is by accurately tracking all deductible business expenses. This includes home office deductions, travel costs, professional services, and health insurance premiums. Additionally, high earners might consider restructuring as an S-Corp to pay themselves a reasonable salary and take the remaining profit as a distribution, which is not subject to self-employment tax.
