About this tool
Self-employed contractors and freelancers face a unique tax burden: you owe both income tax and self-employment tax (Social Security and Medicare), with no employer to split the cost. Calculating what you actually owe—and what to set aside each quarter—is complex and easy to get wrong. Most people either overpay out of caution or underpay and face penalties. This tool solves that by computing your exact self-employment tax liability from your net income.
You need this calculator if you file a 1099, earn income as a sole proprietor, or run a side business. Whether you're a freelancer, consultant, contractor, or small-business owner, you must estimate quarterly tax payments to avoid underpayment penalties. Waiting until tax day to discover you owe thousands is stressful and expensive. This tool lets you see the full picture right now and plan accordingly.
Free tax calculators online are either too generic (they ignore self-employment specifics) or they demand you enter dozens of fields and still give you an incomplete picture. This AI-powered tool cuts through the noise by focusing on the one number that matters—your net self-employment income—and instantly returns your self-employment tax, effective tax rate, and recommended quarterly payment amounts. No guessing, no outdated tables.
Example: A freelancer with $75,000 net self-employment income enters that amount. The tool shows: self-employment tax owed ($10,605), quarterly estimated payment ($2,651), net income after SE tax ($64,395), and an itemized breakdown of Social Security vs. Medicare portions. The paid report includes a downloadable PDF you can save, forward to your accountant, or file with your quarterly payments.
