DT8257 - Double Taxation Relief Manual: Guidance by country: Greece: Dividends
There is no dividend Article in the agreement. Greece does not levy a withholding tax on payments of dividends.
The agreement does not provide for credit for underlying tax (see INTM164010(d)), but where a United Kingdom company controls, directly or indirectly, not less than 10 per cent of the voting power in the Greek company paying the dividend, credit is due unilaterally for such underlying tax.
