HM Revenue and Customs (HMRC) is to close its regional offices in Derry.
Foyle House is one of six regional HMRC offices which currently operate across the North of Ireland.
The other offices are in Coleraine, Newry, Craigavon, Enniskillen and Lisburn.
The Derry office is scheduled to close around the year 2020/2021.
HMRC said it is phasing the closures to “allow staff time to make choices for their future” and reduce redundancies.
In 2013, HMRC also began a voluntary redundancy scheme for some staff in Derry, Enniskillen, Newry and Belfast.
HMRC expects between 1,300 and 1,600 full-time equivalent employees to work in the Belfast regional centre.
Lin Homer, HMRC’s chief executive, said: “The new regional centre in Belfast will bring our staff together in more modern and cost-effective buildings in an area with lower rent.
“It will also make a big contribution to the economy of Northern Ireland providing high-quality, skilled jobs and supporting the government’s commitment to a national recovery that benefits all parts of the UK.”
