The United States is one of the few governments to tax the international incomes of its citizens and permanent residents residing abroad. However, there are provisions that protect against possible double taxation. This includes an agreement between the New Zealand government and the Australian government to avoid double taxation of income and ancillary benefits. The treaty has several objectives, the most important of which is the possibility of facilitating double taxation. To facilitate this objective, the two bodies of national legislation, the New Zealand Income Tax Act and the United States Internal Revenue Code, refer to the treaty. The withholding rate for non-residents is 15% and could be reduced as a result of the agreement between these countries on double taxation. DBAs reduce double taxation more than national legislation prefers. Article 13, paragraph 6, of the agreement was introduced to avoid double taxation of capital gains on outgoing residents. Under the Australian CGT scheme, a person who no longer has a home in Australia is normally taxed on unrealized profits of CGT assets held on that date, with assets other than taxable assets.
However, a person who ceases to have an Australian-based tax may choose, at the time of departure, to either pay taxes (based on the difference between the market value of the non-taxable Australian assets at the time of departure and the cost base of those assets), or to defer tax on a possible profit until the effective disposal of these non-taxable Australian assets. In both cases, this person is treated as if he had disposed of tax-free Australian assets and acquired it at fair value if, under New Zealand tax law (which currently does not impose capital gains), he is no longer resident in Australia. The U.S.-New Zealand tax contract includes double taxation on corporate, corporate and capital gains taxes, but a clause known as the Savings Clause in Article 1, paragraph 3, states that „the United States may require that the tax deduction is a 15% tax deduction. , which can be reduced under the U.S. double taxation agreement with New Zealand. All DBAs include the POP as a low-cost dispute resolution mechanism. As a general rule, the POP only provides for the relevant authorities to work to resolve the problem. However, some POPs provisions are supplemented by arbitration provisions to eliminate cases where the relevant authorities are unable to reach an agreement. There is currently no social security agreement (or totalization agreement) between the U.S. government and the New Zealand government.
