We will explain how this may apply to you. Ireland has signed comprehensive double taxation (SAA) conventions with 74 countries; 73 are in force. The treaties concern direct taxes which are in the case of Ireland: in another scenario, a double taxation convention may provide that income which is not exempt is collected at a reduced rate. For more information, see help sheet HS304 “Non-residents – Relief under double taxation treaties” on GOV.UK. The OECD is an organisation of developed countries whose objective is to develop world trade and maintain stability. The OECD has published a Model Double Taxation Convention which forms the basis of most double taxation treaties between Western countries. If you come to the UK and have UK work income that is taxed in your home country, you normally have to pay UK taxes. Your home country should give you double tax relief by giving a credit for UK taxes paid. However, if you are established in a country with which the UK has a double taxation treaty, you may be entitled to an exemption from UK tax if you spend less than 183 days in the UK and have an employer outside the UK.
A non-resident is taxable in respect of the UK obligations of his employment. An Irish resident is exempt from UNEMPLOYMENT INCOME TAX in the UNITED Kingdom if the following conditions are met: the beneficiary is not present in the United Kingdom for more than 182 days in the tax year; and the remuneration is paid on behalf of an employer who is not established in the United Kingdom and who is not remunerated by a permanent establishment located in the United Kingdom. The provisions of the Article shall not apply where the main purpose of the operation is to make use of the Article. . . .
