It is 3 of the previously available 4 agencies. Tax man is certainly taking an interest in Norwegian nationality contractors, but the greater majority of them are
AFAIK compliant at home anyhow.
Social tax burden placed on agencies/pilots , NAS smells like roses for the Norwegian public , & justice is seen to be done. . . simples.
Tax , which is in reality your affair between you & your resident country (or in some cases your country of employment) thrust upon contractors at "Base Country" ( quite arbitrarily) & those paying at home left to sort their own mess out (not too easy for Danish colleagues working in Spain)
Ill thought out / rushed through/ "one size fits all" solution, whose only purpose is to try & make NAS look whiter than white to the Norwegian public. . . . until the SAS Union & the NPF start stirring it up about the future Dreamliner operation.
This one will run & run.
