As a resident of Germany, Austria or Switzerland, you are subject to the worldwide income principle and must therefore pay tax on your worldwide income, including income from a company in Dubai, in your country of residence. All income, including profits from your company in Dubai and investments in foreign companies, must be declared in your tax return. Income that remains in your company's business account in Dubai and is not distributed to you is generally not taxed immediately as it is considered business income of the company. Please note the CFC (Controlled Foreign Company) regulations for controlled foreign companies, as these could be relevant for your company in Dubai, especially if your income is predominantly passive. In addition, proof of your company's actual business operations in Dubai is required for tax purposes.
