Estimate your self-employment tax and quarterly payments. Know exactly what to set aside.
Self-employment taxes are one of the biggest surprises for new freelancers. Unlike traditional employees who have taxes withheld automatically, freelancers must estimate, set aside, and pay their own taxes quarterly. This free Tax Estimator helps you plan ahead so you are never caught off guard by a large tax bill.
Select your country from the available options — United States, United Kingdom, India, Australia, or Canada. Enter your estimated annual freelance income and business expenses. For US users, you can also choose your filing status (single or married filing jointly). The tool instantly computes your net taxable income and applies the relevant tax brackets, self-employment levies, and deductions for your jurisdiction.
The results show your estimated quarterly payment (due four times per year), a monthly savings target, and a full breakdown including income tax, self-employment tax equivalent, and effective tax rate. Use the monthly savings amount as a guide for how much to transfer to a separate savings account each month so you are ready when payments are due.
Rates vary by country and income level. The US uses progressive federal brackets (10–37%) plus the 15.3% self-employment tax (Social Security and Medicare). The UK applies income tax (20–45%) plus Class 4 National Insurance (9% on profits between £12,570 and £50,270, then 2% above). Each country has its own progressive bracket structure and self-employment levies.
The tool divides your estimated total annual tax by four to give your quarterly payment amount. In the US, quarterly estimated payments are due April 15, June 15, September 15, and January 15 of the following year. The tool includes a dedicated table showing US quarterly due dates with corresponding payment periods.
Common deductible expenses include home office costs, software subscriptions, equipment, internet and phone bills, travel, professional development courses, health insurance premiums, and retirement contributions. Deduction rules vary significantly by country — always check your local tax authority's guidelines for what is allowable.
You can switch between countries to compare estimated tax burdens side by side, but the tool models one country at a time. Each country's calculation is independent and uses that jurisdiction's specific tax brackets, deductions, and self-employment levies. The tool currently supports the US, UK, India, Australia, and Canada.
These are estimates for planning and awareness purposes only. Actual tax liability depends on many factors including state or provincial taxes, specific deductions and credits, changing tax laws, and personal circumstances. Always verify your obligations with a qualified tax professional and use official government resources for filing.
