Planning estimate only. The calculation applies the IRS 92.35% net-earnings factor, 15.3% combined self-employment rate and 2026 Social Security wage base. It assumes no other wages use that wage base. The optional income-tax figure applies your chosen rate to profit less half the estimated self-employment tax; it is not a full income-tax calculation. Quarterly is annual estimate ÷ 4, not a payment instruction. If expenses exceed income, profit is shown as zero for tax-estimate purposes. For actual payments, use Form 1040-ES or consult a qualified tax professional.
A plain-English tax guide
Income, expenses, and profit
Income is what clients pay you for work. Business deductions are eligible costs of earning it; profit is income minus those costs. Keep receipts and distinguish business from personal spending. The IRS uses Schedule C to report sole-proprietor business profit or loss.
What self-employment tax covers
Self-employment tax funds Social Security and Medicare. It is separate from federal income tax. Generally, net self-employment earnings of $400 or more trigger it. The 2026 Social Security portion is limited by the wage base, and wages from another job can affect the amount. Read the IRS explanation.
Why quarterly payments matter
Unlike a regular paycheck, freelance payments usually have no federal tax withheld. Estimated payments let you pay toward income tax and self-employment tax during the year. Underpaying may lead to a penalty even if you later receive a refund. The 2026 Form 1040-ES explains who needs to pay and how to calculate it.
Reading your results
Net profit is your starting point, not your final taxable income. The self-employment tax line is a simplified federal estimate. If you enter an assumed income-tax rate, the page adds a rough income-tax amount. Your actual tax may differ because of filing status, other income, deductions, credits, withholding, state taxes and special rules. Use the quarterly figure as a budgeting reference, not as the required IRS payment.
Frequently asked questions
How much should a freelancer set aside for taxes?
There is no universal percentage. Your income tax depends on your whole tax situation, while self-employment tax is a separate calculation. Use the estimate above as a planning starting point, update it as income changes, and use the IRS Form 1040-ES worksheet for a more complete estimate.
When are estimated tax payments due?
For the 2026 tax year, the usual federal installment dates are April 15, June 15, and September 15, 2026, and January 15, 2027. These are payment dates, not four separate annual tax returns. See the 2026 IRS payment schedule for exceptions and updates.
What is the self-employment tax rate?
The federal self-employment tax rate is 15.3%: 12.4% Social Security plus 2.9% Medicare. It is generally calculated on 92.35% of net self-employment profit, with a Social Security wage limit and other special rules. See the IRS explanation.
Do freelancers have to pay taxes on every dollar they earn?
Not necessarily. Ordinary and necessary business expenses can reduce business profit. Income tax and self-employment tax are then determined under different rules; neither is simply a flat percentage of gross client payments. See Schedule C.
What expenses can freelancers deduct?
Eligible ordinary and necessary business costs may include supplies, software used for work, and advertising. Personal expenses are not automatically deductible, and mixed-use expenses need careful allocation. Keep records and consult IRS business-expense guidance.
How do quarterly estimated taxes work?
You estimate annual federal income tax and self-employment tax, account for withholding and credits, and make payments during the year if required. Generally, estimated payments may be needed if you expect to owe at least $1,000 after withholding and refundable credits and meet the IRS underpayment test. Amounts can change when your income changes. Check Form 1040-ES.
Does this calculator include state taxes or my other income?
No. It estimates federal self-employment tax on the freelance figures you enter. The optional federal income tax rate is only a rough planning assumption; this tool does not apply tax brackets, standard or itemized deductions, credits, other wages, state or local taxes, or additional Medicare tax.
