Methodology
This page explains how TaxAtlas collects data, how we evaluate sources, and how updates are handled.
Sources We Trust
We prioritize primary sources such as government tax authorities, ministries of finance, and official legislation portals. We also use respected secondary sources like OECD datasets and Big 4 tax summaries to corroborate details.
What We Measure
We capture key fields including personal income tax rates, corporate tax rates, capital gains, foreign income treatment, residency thresholds, and major compliance notes. Each country page shows its data sources and the most recent update date.
Scoring (Directional, Not Advice)
The personal and business scores are directional indicators designed to help compare jurisdictions at a high level. They reflect rates, foreign income treatment, and practical considerations described on each page. Scores are not a substitute for professional advice.
Update Cadence
We run a weekly source audit. If a source changes, we verify the change and update the data with a documented citation before publishing.
Limitations
Tax regimes vary by individual circumstances. Rates may differ by income bands, residency status, or special programs. Always verify your situation with local professionals.
