New Zealand Revenue Minister Peter Dunne has announced moves to minimise costs for New Zealand banks wanting to comply with the US Foreign Account Tax Compliance Act (FATCA) laws that force banks to provide US authorities with information on dealings with US clients.Dunne said New Zealand was now negotiating a FATCA inter-governmental agreement that would allow New Zealand banks to pass information on to New Zealand's Inland Revenue Department, which would then pass it on to US authorities.Dunne said New Zealand had 37 double-tax agreements and 20 tax information exchange agreements with various governments."We are negotiating the FATCA agreement on the same basis, but we are very aware of compliance cost issues and are looking at how we can minimise any burden," he said.
