Countries tax in more than one direction. As a resident you may be taxed on income from anywhere. As a non-resident you may still be taxed on income that has a source in that country. The second idea is what people mean by source. It is why a move does not close every file you had at home.
The situations that feel like source
Rent from a property in the country you left. Employment duties carried out there. A business that still operates there. Dividends or interest that a payer withholds on because of where the payer is. Each of these can be taxed as source income under local law, or not. The label in a textbook is a prompt to ask, not a computation.
Both countries, one receipt
The country of source may tax because the income arose there. The country of residence may tax because you live there. A treaty, a credit, or an exemption in one of the laws are the usual ways the overlap is reduced. They are not automatic, and they are not identical for rent and for dividends. Keep the evidence of any tax already paid. A credit without evidence is a story.
Source is about where the income is treated as arising
Source-based taxation is the idea that a country taxes income or gains because they arise there, even if the person who receives them lives somewhere else. Rent from a property, a salary for work done in the country, and some dividends or interest are common examples people meet. Whether a particular receipt has a source in a particular country is a legal question, and countries do not all answer it the same way. The phrase is a map, not a verdict on your return.
It sits beside the idea of taxing residents on their worldwide income. You can meet both at once: the country where you live taxes you as a resident, and the country where a property sits taxes the rent because of the property. A treaty may then limit one of those charges or allow a credit. Without a treaty, domestic rules on foreign tax are what you have. Ask a qualified adviser which of these applies to the income you actually receive. Do not apply the label ‘source’ to everything earned abroad and stop there.
Match each payment to a place before you ask how it is taxed
List the payments: who pays them, for what, and from which country. A remote salary can be especially easy to mis-describe, because the employer, the place you sit, and the place the contract names may differ. Note all three. The same discipline helps with a business: where the customer is, where the work is done, and where the company is managed are separate facts.
Keep the contracts and the statements that show the payer’s country. They are what an adviser will use to test source, and what a tax authority may ask for if a return is questioned. This guide does not rank countries as ‘source only’ or ‘worldwide’. That shorthand hides the exceptions, and the exceptions are where people get hurt.
Before you act
When you brief an adviser, resist the urge to lead with a conclusion. Lead with the payment. Who paid it, under which contract, for work or assets in which country, into which account. Do that for rent, salary, dividends and fees separately. The adviser can then tell you whether a source question even arises, or whether residence is the whole of the issue. If you have already taken a view on a form for a bank, show the adviser that form. Self-certifications are easy to complete and awkward to contradict later. Correcting one because the analysis has moved is a sign the process is working.
A practical checklist
- List income that still comes from the country you left.
- Ask whether that country taxes non-residents on it.
- Ask whether your new country taxes it too.
- Check the treaty article, if a treaty exists.
- Keep withholding statements.
- Do not net the two taxes in your head and call it a plan.
Questions to ask
- Does this income have a source in that country if I am non-resident?
- Is tax withheld, and is that the final tax?
- Must I still file there?
- How does my country of residence treat the same income?
- Is a credit or an exemption available?
- Does the way I own the asset change the source?
Common mistakes
- Assuming departure ends every filing.
- Ignoring rent because a tenant pays it to a local agent.
- Treating withholding as a nuisance rather than as tax.
- Applying one treaty article to every kind of income.
- Forgetting that a company you still run may keep a source, or a permanent establishment, alive.
