International double taxation is the 'taxation of the same profits, in the same taxpayer's hands, in the same period, by two or more countries,' explains The Practical Tax Loose Leaf Service. This is also known as juridical double taxation.
But through unilateral relief and international tax treaty relief, you can avoid double taxation and maximise your savings.
Unilateral relief exists where no tax treaties are concluded. Countries use the unilateral relief method to 'avoid double taxation where that country can't conclude any double tax treaties with certain host countries,' says the Loose Leaf.
International treaty relief happens when countries enter into agreements with each other to eliminate or alleviate double taxation suffered by their residents in other countries.
Here's how to determine how you'll be taxed.
The two step solution to solving a double taxation problem
Step #1: Determine if you're a South African resident or not. If you are, then you'll be taxed in South Africa on your worldwide income, irrespective of its source. If you're a non-resident, you'll be taxed on your income or capital gain derived from a South African source or deemed source only.
Step #2: Consider if there's a problem of international double taxation. If you're subjected to taxation on the same profits, during the same period, in two or more countries, determine which country is afforded taxing rights.
Using this two steps approach ensure you save and don't pay tax twice.
