Much work has already happened in that area. There are two things happening specifically. The Revenue Commissioners are either organising seminars or are engaging with representative bodies in different sectors of the economy, explaining to those bodies the kinds of requirements necessary to deal with a third country.

At this point, what the Revenue Commissioners can do is indicate to people the change that is likely to happen and give them enough time to plan for it. There will be change, however.
