Who this is for
A treaty only helps if it is applied — and the conditions matter
Double tax treaties are agreements between two countries that decide which of them may tax particular kinds of income, so that cross-border earnings, pensions, dividends, interest and royalties are not taxed twice. They also often reduce withholding rates, define who counts as resident, and set out how disputes between the two authorities are resolved. But a treaty is not a blanket exemption: each benefit is attached to conditions — about your residence, the nature of the income and how you prove your entitlement — and it must be actively claimed, usually through specific forms and certificates. This matters for anyone with income or assets across a border. A treaty lawyer identifies which treaty applies, which provisions help you, and files the claims so the benefits actually materialise rather than remaining theoretical.
Why treaty benefits go unclaimed
The treaty is there to protect you.
But only if you invoke it.
Every benefit has conditions and paperwork, and a missed step can mean paying tax you were entitled to avoid.
Reduced rates never applied
Treaties frequently cut the withholding tax on dividends, interest and royalties — but the lower rate usually has to be requested in advance with proof of residence, and failing to do so means the full rate is deducted at source.
Not knowing which treaty applies
Where income touches more than two countries, or your residence is uncertain, it can be unclear which treaty governs — and applying the wrong one can leave you exposed or forfeit relief you could have claimed.
Conditions you did not meet on paper
Treaty benefits often depend on formalities — a valid residency certificate, specific forms, declarations — and if the paperwork is missing or wrong, the authority can simply deny the relief you were counting on.
What you get
Treaty relief secured, not just understood
We match you with lawyers who apply double tax treaties in practice, not just in theory.
The right treaty identified
Your lawyer determines which treaty applies to your cross-border income, confirms you qualify as a resident under it, and pinpoints the specific provisions that reduce or remove your tax.
Reduced withholding obtained
Where a treaty lowers withholding on dividends, interest or royalties, your lawyer secures the reduced rate at source through the correct forms and residency certificates — before the tax is deducted.
Residency and entitlement proven
Your lawyer obtains the certificates and prepares the evidence that establish your treaty residence and your right to each benefit, so the authorities accept the claim the first time.
Treaty disputes handled
If an authority denies a treaty benefit or two countries disagree over who may tax you, your lawyer invokes the treaty’s dispute procedures and argues your position with the evidence to back it.

Frequently asked
Double tax treaties — common questions
What is a double tax treaty?
A double tax treaty is an agreement between two countries that allocates the right to tax particular types of cross-border income — such as salaries, pensions, dividends, interest and royalties — so the same income is not taxed in both. It also sets reduced withholding rates and a way to resolve disputes between the two tax authorities.
How do I know if a treaty applies to my situation?
A treaty applies if you are resident in one of the two countries and your income arises in or involves the other, and the specific type of income is covered. Because the analysis depends on your residence status and the nature of the income, a lawyer can confirm which treaty governs and whether it helps you.
What is a residence certificate and why do I need one?
A residence certificate is a document from a country’s tax authority confirming you are tax resident there, and it is usually required to claim treaty benefits such as reduced withholding. Without it, the authority at source may refuse the reduced rate, so it is typically the first document a treaty claim needs.
Can a treaty reduce the tax withheld on my dividends or interest?
Often, yes. Many treaties cap the withholding tax on dividends, interest and royalties at a lower rate than the domestic default. The reduced rate is not automatic — it must be requested, usually in advance, with proof of residence — which is where a lawyer’s preparation matters.
What happens if a country refuses to apply a treaty benefit?
Most treaties contain a procedure, such as a mutual agreement procedure, that lets you ask the two authorities to resolve the issue. If a benefit is wrongly denied, you can challenge it — and a lawyer experienced in treaty disputes can pursue that process on your behalf.
Do I need a lawyer to claim treaty benefits?
Not always, but the conditions, forms and evidence are easy to get wrong, and an incorrect claim can be refused or trigger a correction. Where the income is significant, your residence is uncertain or a claim has been denied, a lawyer materially improves the chance of securing the relief you are entitled to.
