National interest analysis and Select Committee consideration

Since 2002, DTAs, protocols and TIEAs have been subject to Parliamentary treaty examination (Parliament’s Standing Orders 397-400). This involves a Select Committee considering a national interest analysis. For treaties with regulatory impacts, the national interest analysis must cover all of the requirements normally considered in a regulatory impact assessment. The national interest analysis is published as part of the Select Committee report back to the House, and links to these reports are included on each country's tax treaty web page.

Double tax agreements

New Zealand has a network of 40 DTAs in force with its main trading and investment partners. DTAs reduce tax impediments to cross-border trade and investment and assist tax administration. To find out more about DTAs see the role of double tax agreements.

United States Intergovernmental Agreement (FATCA)

New Zealand has an intergovernmental agreement with the United States for their Foreign Account Tax Compliance Act (FATCA). This helps financial institutions minimise their compliance costs in meeting FATCA's reporting requirements.

Automatic Exchange of Information (AEOI) and Common Reporting Standard (CRS)

Although not represented by any specific treaty, the AEOI initiative provides for the exchange of FATCA-type information under the OECD Convention on Mutual Administrative Assistance in Tax Matters and under some DTAs. The CRS sets out the international rules for the collection and reporting of this information.
