Extract:-
Article 17
PENSIONS
Subject to the provisions of paragraph 2 of Article 18, pensions and other similar remuneration paid to an individual who is a resident of a Contracting State, shall be taxable only in that State.
Article 18
GOVERNMENT SERVICE
1. a) Salaries, wages and other similar remuneration paid by a Contracting State or a political subdivision or a local authority thereof to an individual in respect of services rendered to that State or subdivision or authority shall be taxable only in that State.
b) However, such salaries, wages and other similar remuneration shall be taxable only in the other Contracting State if the services are rendered in that State and the individual is a resident of that State who:
(i) is a national of that State; or
(ii) did not become a resident of that State solely for the purpose of rendering the services.
2.a) Notwithstanding the provisions of paragraph 1, pensions and other similar remuneration paid by, or out of funds created by, a Contracting State or a political subdivision or a local authority thereof to an individual in respect of services rendered to that State or subdivision or authority shall be taxable only in that State.
14b) However, such pensions and other similar remuneration shall be taxable only in the other Contracting State if the individual is a resident of, and a national of, that State.
3. The provisions of Articles 14, 15, 16 and 17 shall apply to salaries, wages, pensions, and other similar remuneration in respect of services rendered in connection with a business carried on by a Contracting State or a political subdivision or a local authority thereof.
Put simple
All pensions, 0ther than Crown Pensions (police, military, NHS, etc) are taxed in the country where one is resident. . Thus a UK private pension, or an OAP for a person resident in Spain, is taxable only in Spain.
One just informs HMRC (UK tax office) that you have moved to Spain and the UK and Spanish tax offices liaise.
One also needs to inform bank, Buildimg Sociey etc., that you tax free in UK as you must declare the income in Spain. You will then get interest etc gross.
