Who this is for
For people and businesses whose tax life does not stop at one border
Cross-border tax planning deals with the situations that arise when your affairs touch more than one tax system — an expatriate earning in one country while resident in another, a founder with companies in several jurisdictions, a family with property or investments abroad, or an executive posted overseas. Each country applies its own rules on residence, source of income and reporting, and the interaction between them is governed by double tax treaties, tie-breaker provisions and disclosure obligations that are technical and easy to get wrong. The goal is not to hide anything but to ensure you are not taxed twice on the same income, that you claim the reliefs you are entitled to, and that you meet every filing duty in every country involved. We match you with a tax lawyer who coordinates the full picture rather than treating each country in isolation.
Why cross-border affairs go wrong
Cross-border tax rarely fails because one country is unfair.
It fails because nobody coordinated the whole picture.
Residence, treaties and reporting obligations each pull in a different direction — and a piecemeal approach leaves gaps and double taxation.
Double taxation
The same salary, dividend or gain can be taxed in two countries at once when residence and source rules overlap. Relief through a treaty exists, but only if you claim it correctly and on time.
Unclear residence
Being treated as tax resident in two countries, or in the wrong one, changes everything about what you owe and where. Residence tie-breakers are technical and often decided on facts you would not think matter.
Missed reporting duties
Holding a foreign account, trust or company often triggers disclosure obligations in your home country, with significant penalties for silence. Many people simply do not know the duty exists.
What you get
A tax lawyer who sees the whole cross-border picture
We only match you with tax lawyers who coordinate multiple jurisdictions, treaties and reporting regimes as a single plan.
Residence & treaty analysis
Your lawyer determines where you are actually tax resident, how the relevant double tax treaties apply to your income and assets, and what that means for what you owe in each country.
Double tax relief
Where the same income could be taxed twice, your lawyer identifies the available reliefs — credits, exemptions or treaty provisions — and ensures you claim them properly so you pay once, not twice.
Coordinated structuring
Businesses and holdings spanning borders are structured carefully so all the pieces work together across jurisdictions, rather than each country’s arrangement quietly undermining the next.
Full disclosure handled
Foreign assets, accounts and entities carry reporting obligations that vary by country. Your lawyer maps every duty and files what is required, so nothing is left undisclosed by accident.

Frequently asked
Cross-border tax — common questions
How do I know where I am tax resident?
Residence is decided by each country’s own rules, often weighing days spent there, your home, family and centre of vital interests. You can be resident in more than one country, and treaties then apply tie-breakers. A lawyer can determine your actual position with confidence.
What is a double tax treaty?
It is an agreement between two countries that allocates taxing rights and prevents the same income being taxed twice, typically through credits or exemptions. The precise terms vary from treaty to treaty, and claiming the relief correctly requires care.
Can I be taxed twice on the same income?
Yes, if two countries both claim the income and no relief is applied. Most countries provide mechanisms — through treaties or domestic credits — to prevent this, but you must invoke them correctly. A lawyer ensures you do.
Do I have to report foreign bank accounts or companies?
In many countries, yes. Holding foreign accounts, investments or entities commonly triggers disclosure obligations, and failure to report can carry serious penalties even when no tax is owed. A lawyer can confirm exactly what you must file and where.
Does relocating for work affect my cross-border taxes?
It can significantly. Your salary, benefits and any equity may become taxable in more than one country, and timing of the move matters. A lawyer can plan the move so your obligations and reliefs are handled from the outset.
How can I avoid double taxation on my investments abroad?
By understanding which country taxes the income, what the relevant treaty provides, and which credits or exemptions apply — then structuring and reporting accordingly. This is precisely the coordination a cross-border tax lawyer handles.
