Nadia Brennan

Nadia Brennan is the International Tax & Relocation Editor at TaxPros Rated. She leads the research and verification behind the site's expat-tax guides and the Worldwide Tax Rates Index, focusing on cross-border personal taxation: residency tests, special expat regimes, and how income, capital gains, and inheritance are treated for people moving between countries.

Every figure she publishes is traced to a primary source - PwC Worldwide Tax Summaries, the OECD, and national tax authorities such as the IRS, HMRC, the ATO, and the CRA - and carries the date it was last verified. Each rate is cross-checked against a second authority before it ships. Where a jurisdiction sits outside the main references, as some microstates do, the source is named in-line so readers can see exactly where a number comes from.

TaxPros Rated is an informational publisher, not a tax adviser, and these guides are not personalized tax advice. Nadia’s role is to keep the public rules accurate, current, and easy to compare - and to point readers to a qualified professional for their own circumstances. Every page links to a corrections process for reporting anything that looks out of date.
