Do dual citizens pay taxes in both countries?

Typically, yes you will be subject to taxation obligations in both countries if you hold dual citizenship.

If the tax rates in the 2 countries are different, you’ll pay the higher rate of tax. The tax year may start on different days in different countries.

A double tax treaty between South Africa and the United Kingdom was ratified by both countries on 17 December 2002 and entered into force in South Africa with effect from years of assessment which commenced after 1 January 2003.

Double taxation agreements do not apply to tax on gains from selling UK residential property.

However for example, if an individual who is resident in the UK but has rental income from a property in another country, will most likely have to pay tax on the rental income in both the UK and that other country.

This is a common situation for migrants regarding UK taxes who have come to the UK to work to find themselves in.

Another common situation when double taxation occurs is where an individual who is not resident in the UK but who has UK-sourced income and remains tax resident in their home country will still have to pay tax for both countries.

A double tax agreement effectively overrides the domestic law in both countries.

For example, if you are non-resident in the UK and you have UK bank interest, this income would be taxable in the UK as UK-sourced income under domestic law.

However, if you are resident in South Africa, the UK-South Africa double tax agreement states that the interest should only be taxable in South Africa.

This means that the UK must give up its right to tax that income. In this situation, you would make a claim to HMRC ( this would usually be made on a Self Assessment tax return) to exempt the income from UK tax.

Yes, you are eligible for potential tax obligations for both countries that you have citizenship for. This could be foreign income tax, residency tax if you own property in either country, or other situations where tax is payable.

You should always double check if you are subject to pay income tax in either of the countries that you hold citizenship for, or the country you are residing in. There may also be tax in the country where the income was earned.

Most countries submit to the idea that taxation should be only national, not global.

The two exceptions lie in the United States and China, who both require their citizens living abroad pay domestic taxes on worldwide income, regardless of whether they are a resident alien or not.

So what are the advantages of dual citizenship? A dual citizen is obliged under national laws and regulations of both countries they have citizenship with.

For instance, some disadvantages could include:

• Career limitations
• Double taxation in line with tax laws
• Dual responsibilities and obligations
• Complex citizenship process
• Limited assistance from your native country.

As a South African dual citizen, you can use your British passport and nationality freely when travelling outside South African.

However, if you are in South Africa, you are not allowed to use your UK nationality to gain an advantage or to avoid any responsibility or duty which you would otherwise have or not have been entitled to.

Whether British citizens are entitled to tax your worldwide income varies depending on your residency status.

You must be a registered British citizen to receive tax credits for all incomes in the world. Non-resident taxation applies to UK sources of income.

Obviously the above rule has exceptions. Consult a qualified immigration lawyer to discuss your status and tax laws.
