Frequently asked questions

Do I pay self-employment tax on all my freelance income?

In the U.S. you owe self-employment tax on net earnings of $400 or more from freelancing or gig work. Most other countries treat it as part of your income tax instead, so check your local rules. This calculator estimates the U.S. 15.3% rate on your profit after expenses.

What counts as a deductible business expense?

Ordinary and necessary costs directly tied to your work — software, a portion of home internet, equipment, professional subscriptions — can lower your taxable profit. Personal spending does not. Keep receipts; rules vary by country.

Should I set aside 30% of every payment?

A common rule of thumb is to reserve 25–35% of each payment for tax if you are a U.S. sole proprietor, then true up at filing. The exact share depends on your profit, deductions, and where you live.

What self-employment tax actually is

If you work for yourself, you pay both the employee and employer halves of Social Security and Medicare — 15.3% combined on net earnings. It is separate from income tax, and it applies once your net self-employment earnings reach $400 in a year, even if you owe no income tax at all.

Two things most people miss: the tax is calculated on net profit (revenue minus legitimate business expenses), and you are allowed to deduct half of what you pay. Both can move the number by thousands of dollars.

How the calculation is built

Net profit is multiplied by 92.35% first, then the 15.3% rate is applied. Social Security (12.4%) only applies up to an annual wage base; Medicare (2.9%) has no cap and increases at higher incomes. This calculator applies those pieces in order and shows the deductible half separately so you can carry it to your return.
