New Double tax agreement with the United Kingdom signed

New Zealand and the United Kingdom have signed a new double tax agreement (DTA) to replace the current agreement. Which entered into force in 1984.

The new DTA with the United Kingdom will better support cross-border trade and investment between the two countries by providing greater certainty to taxpayers on their tax obligations, while protecting New Zealand’s interests. It also includes key anti-abuse provisions developed by the OECD to prevent base erosion and profit shifting.

The new DTA will enter into force after both countries have completed the necessary domestic procedures, which in New Zealand’s case will require an Order in Council.
