Free Freelance Tax Estimator

Freelancers pay self-employment tax of 15.3% on net earnings (12.4% for Social Security up to the wage base limit, plus 2.9% for Medicare) in addition to regular income tax. Employees only pay half of this (7.65%) because their employer covers the other half. This means a freelancer earning $100,000 pays approximately $14,130 in self-employment tax alone — before income tax. However, freelancers can deduct the employer-equivalent half (7.65%) from their adjusted gross income, and they have access to numerous business deductions that W-2 employees cannot claim, which partially offsets the higher tax burden.

Self-employment tax was established by the Self-Employment Contributions Act (SECA) of 1954, extending Social Security and Medicare taxes to self-employed individuals who were previously excluded from the system. Before SECA, self-employed workers didn't contribute to Social Security and therefore didn't qualify for benefits. The rate has increased over the decades — from 3% in 1954 to the current 15.3% (combined Social Security and Medicare). The Additional Medicare Tax of 0.9% on earnings above $200,000 was added by the Affordable Care Act in 2013. Understanding this history helps explain why the rate feels high — you're paying both the employee and employer portions of a system originally designed for traditional employment.

The most frequently overlooked deductions include: home office expenses (simplified method allows $5/sq ft up to 300 sq ft), health insurance premiums (fully deductible for self-employed individuals), retirement contributions (SEP-IRA allows up to 25% of net earnings), business miles driven (67 cents per mile for 2024), professional development and courses, software and tools used for work, professional association memberships, and the employer-equivalent portion of self-employment tax itself. Many freelancers also miss the Qualified Business Income (QBI) deduction, which allows eligible freelancers to deduct up to 20% of qualified business income — potentially saving thousands annually.

The IRS quarterly payment schedule follows an uneven pattern that trips up many freelancers: Q1 is due April 15, Q2 is due June 15 (only 2 months later), Q3 is due September 15, and Q4 is due January 15 of the following year. Miss a payment or underpay, and the IRS charges a penalty calculated as interest on the underpayment. The safe harbor rule protects you from penalties if you pay at least 100% of last year's total tax liability (110% if AGI exceeds $150,000) or 90% of the current year's liability — whichever is lower.

A common rule of thumb is 25–30% of gross income for combined federal income tax and self-employment tax, though the actual amount depends on your total income, filing status, and deductions. For freelancers earning $50,000–$100,000 with typical deductions, 25–28% is usually sufficient. For higher earners in the 32%+ income tax bracket, 35–40% may be needed. The estimator calculates your specific percentage based on your actual numbers, which is far more accurate than a generic rule of thumb.

No — this estimator provides approximate calculations to help you plan cash flow and set aside appropriate amounts throughout the year. Tax law is complex and changes frequently, and individual circumstances (state taxes, multiple income sources, investments, dependents, business entity type) can significantly affect your actual liability. Use this tool for planning and quarterly budgeting, and work with a CPA or tax professional for your annual filing. The estimator covers federal self-employment and income tax but does not calculate state income tax, which varies widely.
