About GigTax
GigTax was built by people who have lived the freelance life: irregular income, clients in different countries, quarterly filings, and the frustration of trying to make sense of tax tables designed for salaried employees.
We created this tool because every other calculator we found was either locked behind an account, focused on a single country, or assumed a fixed paycheck. That doesn't match how freelancers, contractors, and independent professionals actually earn.
Our goal is simple: give you a fast, honest estimate of self-employment tax, national income tax, and regional or state tax using published 2026 rates for 53 countries and 140+ regions, while being clear about what the tool can and cannot do.
Nothing leaves your browser
All calculations run client-side. No accounts, no tracking of financial inputs, no data sent to a server.
Built for speed
Every page is pre-rendered, with no loading spinners and no waiting on a backend.
Global by default
Built for the global freelance economy, not just one country's tax system.
Why this exists
Our numbers are drawn from official tax authority publications and built around the realities of self-employment: variable earnings, business expenses, and regional rates. We want you to feel confident the calculator is grounded in real data and honest about its limits.
