新西兰怎么弄税号？
拿到签证后，登陆税务局网站注册Tax File Number（TFN），网址是URL 选择My tax and super 登录。 点击Get a TFN 输入信息，地址一定要填写在新西兰的地址。
我第一次申请TNN的时候因为公司即将开业，所以填了国内的公司地址和电话。结果收到邮件通知说我的住址无法联系，要求我补充材料或者重新申请。
于是我马上给税务局发了邮件解释情况并提供了新地址。几天以后收到了改签的邮件。 所以大家一定不要偷懒，填错就麻烦了！而且要如实申报自己的收入，如果报低会影响退税。 如果报税时发现有漏报的收入，在补报时需要缴纳43%的税款。但如果及时补报，是可以申请退税的。 每年4月1日到4月5日是报上年的tax return的时间。
New Zealanders and residents must complete and file an income tax return for each year. This includes people who did not earn any income from New Zealand sources during the period， or whose only income was a few dollars from savings interest. You do not need to pay tax on this small amount of interest – it's not enough to warrant filing a tax return. However， if you did have other income (for example， dividends) you will need to tell us about that in your tax return so we can work out how much tax you owe.
If you are a resident of New Zealand but worked overseas， paid foreign taxes and want to claim those tax credits， you will also need to fill out the relevant parts of the IRD157 form （PDF 86KB） . 海外收入需要填报IRD157表格，可以下载了用word编辑或者直接打印签字扫描发送给他们。
