Government spokesman Finance says no transition period will be introduced26 April 2018
Dutchnews published an article which leaves little hope for expats with the 30% ruling that a transition period will be introduced. So far the government stands its ground in also cutting the 30% ruling for expats who already have the ruling. This might have serious financial problems for expats who intend(ed) to stay longer than 5 years. They have anticipated to having a 30% ruling based income for 8 years.
There is a petition going on though to urge Dutch lawmakers to amend this rule change by allowing expats currently residing in the Netherlands who have been granted 8 years 30% ruling in the past to keep their ruling for the full 8 years.
