Tax on investments and savings

You pay tax on income from all your savings and investments, whether they're in NZ or overseas. Your tax rate is based on your income.

Paying tax on investments and savings in NZ

All NZ citizens and residents pay either Resident Withholding Tax (RWT) or tax at the Prescribed Investor Rate (PIR) on income from savings and investments in New Zealand. You need to choose the correct tax rate or you could face an unexpected bill at the end of the tax year.

Tell your provider — that is, your bank, fund manager or financial advisor:

  • your IRD number
  • the tax rate you should pay, based on your income.

If you have a joint investment, you should use the tax rate of whoever earns the most.

How to pay tax

Rates for RWT

Visit the Inland Revenue (IR) website for information about RWT rates.

Rates for PIR

If your investment is in a Portfolio Investment Entity (PIE) — for example managed funds like KiwiSaver — you pay tax at a different rate, known as PIR. Depending on your income, you pay between 10.5% and 28% tax.

How tax is collected

Your bank or financial provider deducts tax when they calculate the interest or dividends you’ve earned. This happens at least once a year. They pay the tax on your behalf to Inland Revenue and give you a statement of the tax you’ve paid in that financial year. They’ll either:

  • send the statement (IR15) to you, or
  • ask you to log into your IR account (My IR) and download it.

Changing your tax rate

To change the tax rate on your interest or investment income, complete an IR456 form and give it to your financial provider. Sometimes you can also do this over the phone or online.
