Certain overseas government pensions paid in the United Kingdom

The governments of certain overseas territories may pay pensions in the United Kingdom through any public department, officer or agent. These are chargeable to income tax by virtue of Section 615 ITEPA 2003 and not under Section 573 ITEPA 2003 like other foreign pensions.

Certain conditions apply. The pension:
• must be paid to a person who has been employed in overseas government service, or
• to the widow, widower, surviving civil partner, child, relative or dependant of a person who has been employed in overseas government service and
• must be payable in respect of that service.

The pension must also be payable in the United Kingdom to a United Kingdom resident by or on behalf of the government of:
• any country forming part of Her Majesty's dominions
• any other country mentioned in Schedule 3, British Nationality Act 1981 (these are listed in a footnote to Section 320 ICTA 1988)
• any territory under Her Majesty's protection.
Pensions that are payable out of the public revenue of the United Kingdom or of Northern Ireland are not chargeable under Section 615 but will be chargeable as United Kingdom pensions under Section 569 ITEPA 2003 or as pensions under registered pension schemes under Section 579A ITEPA 2003.
