International Tax Lawyers

Paying tax on global wealth can be complicated. We take a proactive approach, helping you stay compliant and making sure you don’t pay more than you should.

International wealth brings international tax challenges.

Our dedicated international tax lawyers can advise on bespoke international tax strategies and manage them on your behalf.

If you have assets and investments in different countries, your wealth is affected by a variety of different tax regimes, regulations, and cultural issues. Ex-pats, non-doms, and foreign nationals living in the UK are all affected by international tax law, too.

Staying legally compliant while taking advantage of all tax efficiency opportunities is complicated, time-consuming, and requires deep, technical knowledge.

We can advise on:

  • Cross-border tax planning
  • HMRC disclosures and enquiries
  • Tax compliance and completing UK tax returns
  • Using international tax treaties and conventions
  • Tax-efficient structuring of UK and cross-border investment
  • UK tax matters for individuals and families moving to or from the UK
  • Tax domicile and residence for you and your trusts, foundations and companies
  • Your obligations for disclosing financial information under the Common Reporting Standard
