TEN HMRC offices are to close in the north, with services centralised in Belfast, as part of UK-wide modernisation plans.
Facilities in Newry, Coleraine, Craigavon, Derry, Enniskillen and Lisburn will shut with four offices in Belfast in the period 2016 to 2021.
Staff and services are being centralised in a new regional centre in Belfast, the exact location of which has yet to be made public.
HMRC said in situations where staff were unable to relocate it would do "everything it reasonably can" to help them to find new roles, either elsewhere in the civil service or outside it.
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."
Foyle MP Mark Durkan, whose constituency is served by the Derry facility, criticised the decision to close local tax offices.
"Yet again we have a move which shows contempt for good staff, for local customers and for the regional economy," said the SDLP representative.
"Treasury Ministers need to listen not just to the valid concerns and grievances from people here but also to the questions raised by many reports about the performance capacity of the Revenue & Customs service being strategically diminished.
"Ministers are presiding over an approach which is shrinking public employment, damaging public service and compromising public finances for the future."
Ulster Unionist MP for Fermanagh and South Tyrone Tom Elliott, whose constituents use the Enniskillen office, said he was "furious" at the move.
"It is now two years since HMRC announced a voluntary exit scheme, at the time I and others warned that this was the beginning of the end for a number of HMRC offices, unfortunately we have been proved correct," he said.
"This is a major concern, particularly in the west of the province, where this will leave a huge gap in HMRC front line customer service provision. I have received several complaints in recent weeks about the lack of customer service support, with helpline calls not being answered. This decision will certainly not help local businesses and the wider public.
"There appears to be a gradual removal of public sector services away from Fermanagh. This would be a double blow to the area - the loss of jobs and the loss of front line customer services.
"I have spoken to a HMRC representative today and intend on making further representations, including to the Secretary of State and Chancellor of the Exchequer."
