When a overeas company︂ directly makes an investment in a Seychelles Company, the withholding tax in the Seychelles will︃ be 15% on dividends and 10% on interest on investment made within the Seychelles. Now here comes the catch..... When the investments are made in the Seychelles by a︄ way of loan or capital through the Cyprus company, the payouts made from the Seychelles︅ in form of dividends or interest is tax free, due to DTA Treaty with Cyprus︆ and vice versa.
A Seychelles company has made investments in countries like India, CIS countries︇ or outside of EU with whom Cyprus has treaties very easy and simplifies the entire︈ process. Payouts from a Cyprus Company will be at 0% Tax rate due to the︉ DTA of Cyprus with the Seychelles or any other country that Cyprus has a treaty︊ with. Dividends or interest received by the Seychelles Company will have 0% withholding tax as︋ there is no deduction at source in Cyprus on payouts made to a non-resident.
Useful information: Cyprus companies can incorporate mutual funds in the Seychelles for investments to and︌ from EU and CIS countries, as well as to reach out to countries like South︍ East Asia where the Seychelles has favourable double taxation treaties.
