On 24 May 2017, the Norwegian Government notified several amendments to the Norwegian tonnage tax regime in order for the regime to be approved by EFTA Surveillance Authority (ESA) as compliant with EEA law.

As ESA will not be able to approve the tonnage tax regime before 1 July 2017, the Government applied for a six months prolongation of the existing tonnage tax regime.

On 24 June 2017, ESA notified that the Government's application was approved and thus the existing regime will continue throughout 2017.
