Opposition parties had accused the Government of creating confusion over the issue.
It is understood some taxpayers will have their relief stopped until the Revenue Commissioners establish if they are entitled to continued relief.
However, Government sources have indicated that this will not affect first time buyers, and claimed that it will only apply to a minority of other home owners.
In his Budget speech, Minister for Finance Brian Lenihan said mortgage interest relief would be restricted to the first seven years of a mortgage.
Since then, the Revenue Commissioners have been in discussion with the banks about how that can be done.
The situation is clear for first time buyers, but it is more confused for people on their second or third mortgages - and it is likely that at least some of them will have their relief stopped until Revenue can establish if they are entitled to continued relief.
In a statement this evening, the Revenue Commissioners said that the relief at source would be reactivated in June where an entitlement is established, and that any arrears will be credited to their accounts automatically.
