Practice area guide
What does a tax lawyer do?
Tax law covers income, corporate, indirect and property taxes, tax planning and structuring, cross-border issues such as double tax treaties and transfer pricing, and disputes and audits with the tax authority. Lawyers work alongside accountants, focusing on legal interpretation, structuring and contentious matters.
How do I choose a tax lawyer?
- Decide whether you need planning or a dispute; ask for experience in that specific kind of work.
- For cross-border matters, ask how the lawyer coordinates with advisers in the other countries involved.
- Bring tax returns, assessments, audit letters and the documents behind the transactions in question.
