How This Free Freelance Tax Calculator Works

This free freelance tax calculator walks you through the exact same steps a tax professional uses to estimate your freelance taxes. Here is how to use it:

Step 1 — Enter Your Freelance Income and Expenses

Enter your total freelance revenue (before expenses) and your deductible business expenses. The calculator subtracts your expenses from your gross income to find your net self-employment income — the number the IRS uses to calculate your taxes.

Step 2 — Add Your Filing Status and Other Income

Select your filing status and enter any W-2 income from a regular job. If you have both freelance and W-2 income, the calculator accounts for the Social Security wage base so you are not double-taxed. You can also enter retirement contributions (SEP IRA, Solo 401k) and self-employed health insurance premiums — both of which reduce your taxable income.

Step 3 — See Your Full Tax Breakdown

Click Calculate My Freelance Taxes to see your self-employment tax, federal income tax, quarterly payment schedule, effective tax rate, and take-home pay after all taxes. If you have already made estimated payments this year, enter that amount to see your remaining balance due.

What the Calculator Includes

This free freelance tax calculator covers self-employment tax (Social Security + Medicare), federal income tax using 2026 brackets, the half-of-SE-tax deduction, the self-employed health insurance deduction, retirement contribution deductions, and quarterly estimated payment calculations. It also accounts for the Additional Medicare Tax on high earners and properly handles combined W-2 and freelance income.

Frequently Asked Questions

What is self-employment tax?

Self-employment tax is the Social Security (12.4%) and Medicare (2.9%) tax that freelancers pay on their net earnings. When you work as an employee, your employer pays half of these taxes — but as a freelancer, you pay both halves yourself. The total self-employment tax rate is 15.3% on the first $168,600 of net earnings, and 2.9% on earnings above that. Use this free freelance tax calculator to see exactly how much self-employment tax you owe.

How do quarterly estimated payments work?

The IRS requires freelancers to pay taxes throughout the year in four installments rather than waiting until April. This is known as the estimated tax system. Quarterly due dates are April 15, June 15, September 15, and January 15 of the following year. If you do not make quarterly payments and owe more than $1,000 at tax time, the IRS may charge an underpayment penalty. Our free quarterly tax calculator can also help you plan these payments.

What expenses can I deduct as a freelancer?

Common freelance business expenses include: office supplies, software subscriptions, internet and phone (business portion), advertising, professional development, mileage (67 cents per mile for 2024 — check IRS updates for 2026), home office expenses, and contractor payments. These expenses reduce your net self-employment income, which lowers both your self-employment tax and your income tax.

Do I need to file taxes if I made less than $400 freelancing?

If your net self-employment income is less than $400, you are not required to pay self-employment tax. However, you may still need to file a federal income tax return depending on your total income from all sources. This free freelance tax calculator will show $0 for self-employment tax if your net earnings fall below the $400 threshold.

What is the difference between this and the 1099 tax calculator?

Our free 1099 tax calculator focuses on a single 1099 income stream. This free freelance tax calculator is more comprehensive — it handles business expenses, retirement deductions, health insurance deductions, combined W-2 and freelance income, and quarterly payment scheduling. If you are a full-time freelancer or have multiple income sources, this is the better tool to use.

Can I reduce my freelance taxes by contributing to a retirement plan?

Yes. Contributions to a SEP IRA, Solo 401(k), or SIMPLE IRA reduce your adjusted gross income, which directly lowers your federal income tax. These contributions do not reduce your self-employment tax, but they can significantly reduce your overall tax bill. Enter your planned contribution in this free freelance tax calculator to see the impact. Our free 401k calculator can help you plan your contribution strategy.

Understanding Freelance Taxes and Self-Employment

How Freelance Income Is Taxed

Freelance income is subject to two separate taxes: self-employment tax and federal income tax. Self-employment tax covers Social Security and Medicare — the same payroll taxes that W-2 employees split with their employer. As a freelancer, you are both the employer and the employee, so you pay the full 15.3% yourself. Federal income tax is then calculated on your adjusted gross income using the standard tax brackets. This free freelance tax calculator applies both taxes automatically so you see your true total tax obligation.

The Half-of-SE-Tax Deduction

The IRS allows you to deduct 50% of your self-employment tax when calculating your adjusted gross income. This is an “above-the-line” deduction, meaning you get it even if you take the standard deduction. It exists because W-2 employees never pay tax on their employer’s share of payroll taxes — this deduction gives freelancers equivalent treatment. The calculator applies this deduction automatically.

Self-Employed Health Insurance Deduction

If you pay for your own health insurance and are not eligible for an employer-sponsored plan, you can deduct 100% of your health insurance premiums as an adjustment to income. This applies to medical, dental, and qualifying long-term care insurance for you, your spouse, and your dependents. This deduction can save freelancers thousands of dollars per year in federal income tax. Learn more about eligibility at the IRS Tax Topic 502 — Medical and Dental Expenses.

Retirement Savings for Freelancers

Freelancers have access to some of the most powerful retirement plans available, including the SEP IRA (up to 25% of net earnings, max $69,000 for 2024 — check IRS updates for 2026), the Solo 401(k) (allows both employee and employer contributions), and the SIMPLE IRA. These contributions reduce your adjusted gross income and your federal income tax while building long-term wealth. You can explore current contribution limits and rules at the IRS One-Participant 401(k) Plans page.

Common Mistakes Freelancers Make With Taxes

The most common tax mistakes freelancers make are: not paying quarterly estimated taxes (leading to underpayment penalties), forgetting to deduct the half-of-SE-tax deduction, missing legitimate business expense deductions, and not separating personal and business finances. Using this free freelance tax calculator at the start of each year — and updating it quarterly — helps you stay ahead of your tax bill and avoid costly surprises.
