KiwiSaver Tax - Everything you need to know

Tax is not the most riveting subject in the world, nor is it something we like paying, but having the right information when it comes to tax can save you a lot of money. National Capital has done the research so instead of receiving a shock after viewing the tax cuts on our KiwiSaver funds this financial year, let’s try to be a step ahead and understand how KiwiSaver funds get taxed.

KiwiSaver Tax Basics

Firstly, the amount of tax you pay is based on your Prescribed Investor Rate (PIR). Your KiwiSaver scheme will collect your share of the payable tax and pay the IRD on your behalf, in most cases. 

If the IRD believes the tax rate that you selected is incorrect they will contact your KiwiSaver provider directly and have them change it. This can happen if you have selected a lower or higher than accurate PIR rate. 

Prior to 2020, if you didn't supply a PIR, the IRD just applied the highest tax bracket (28%) and there was no chance for a refund. Additionally, if you paid extra tax - tough break - no refund. Luckily for everyone, the law was revised in 2019 and the policy changed as of 1 April 2020.

Also, you only pay tax on the taxable portion of your returns from KiwiSaver, not on the entire balance. Meaning, only some of your KiwiSaver returns are subject to tax. We will get into the reason for that in more depth as we move forward.

What Rate of Tax Will I Pay?

As mentioned above, the amount of tax you pay is based on your Prescribed Investor Rate (PIR) with an upper ceiling of 28%. 

Your PIR for the current tax year depends on how much you earned in the previous two tax years. It’s your responsibility to tell your provider the correct rate, so if you are still unsure, here is a simple tool to help you calculate your PIR. 

Calculating KiwiSaver Tax PIR

The Scheme provider pays the tax on your behalf. To do so, they cancel a number of units you have invested, in order to fund the amount payable to the IRD during the quarter that the tax payable falls on.

Income Tax Rate vs PIR 

It is important to understand that your PIR may be a different rate from your income tax rate. 

You pay income tax to IRD based on your yearly income for the year. The PIR on the other hand takes into consideration your lowest income in the last two income years. Additionally, the bands & minimum and maximum rates for your Income Tax and PIR are different. 

Wrong or missing PIR 

If you do not provide your KiwiSaver provider with a PIR, you will be charged tax at a default rate of 28%. This part of the law has not changed. 

However, the IRD has now put systems in place where they will calculate your PIR themselves and ask you (via your provider) to correct your tax rate if you have registered with an incorrect rate. Should you be due a refund, you will now get paid that money back. 

The refund will be paid directly to your KiwiSaver provider and used by them to buy more units on your behalf in your chosen fund. Should you no longer be in your original Scheme, the refund will then go to either to your new Scheme or be paid directly to you. 

Which Part of My KiwiSaver Money Is Taxed?

Your KiwiSaver earns money for you by investing your contributions. You only pay tax on a portion of these returns, not the principal amount. Additionally, you only pay tax on the taxable portion of your returns.

For example, let's say John has $10,000 balance in his KiwiSaver account which has earned 5% in the current year. This comes to an earning of $500 on his KiwiSaver investment. From this $500, depending on the type of fund he is, all or part of it could be subject to tax.

Your share of the taxable income of the scheme's earnings is calculated daily and attributed to you every quarter.

Taxable Returns In Different Types of Funds 

As we mentioned before you only pay tax on the 'taxable portion' of your returns. The difference in the make-up of your fund can play a big part in how much tax is paid. We did some research to find how much of a fund's returns are made up of taxable income. Using a few of Milford KiwiSaver Plans funds we got an idea of what proportion of these funds returns were taxable. The figures are in the table below.

Different Funds Taxable portion

As seen above, 100% of the Cash funds returns were taxable - while only 33% of the Active Growth Funds returns were taxable for the period in question. This led to a huge difference in how much of an investor's Gross returns were being paid out in tax.

Depending on how the fund manager has invested your money hence can lead to different tax bills which affect your final payout. So it's good to look into these things.

 

Domestic Shares vs International Shares

As most KiwiSaver schemes are PIE schemes,  investments in some Australasian shares are exempted from tax by the Foreign Investment Fund rule. Gains on New Zealand shares are also currently tax-free.

The set of rules for companies that meet the Australian company share exemption criteria are as follows: 

  • A company must be included in the official ASX list,

  • The company is an Australian resident and is not  considered a resident of any other country under an agreement reached between Australia and the other country,

  • The company maintains a franking account, and

  • The company offers stock that is not stapled.  

KiwiSaver providers share with the public and their clients the companies they invest in for the different schemes they have. If you are curious to find out which companies are exempt from paying tax you can access the ASX list and search for the companies shown in your scheme’s list of investments. The investments made on those companies are the ones you are not paying tax on. 

The IRD considers this list as reasonable care when taking a tax position. Therefore, you as the investor will not be penalized (will not owe money to the IRD) should changes to this list be made before your scheme provider knows about and is able to take the necessary steps to allow for PIR adjustments.

You can do the same for New Zealand companies and find them on the NZX50 list if you are curious to create a more detailed view on which parts of your investment are not subject to tax. 

The value of this tax-free status is very valuable, particularly for younger investors who may be in KiwiSaver for 30-40 years and so get the compounding benefit of tax-free gains for a long period. 

However, tax on other international shares is paid on the income you derive from those shares.

For example, let's assume John’s KiwiSaver scheme has a total balance of $10,000, of which $4,000 are invested in Australasian equities or shares, while the other $6000 are invested in international shares. According to the current taxation rules, the ‘income’ on the $4000 which are invested in Australasian shares are tax-free. However, John will have to pay tax on the ‘income’ he earns from $6000 from the international shares at his PIR rate.

Below is an example of a fund with a percentage of the total assets invested in cash, Australasian and international assets to better understand the distribution of assets in KiwiSaver fund investments.

KiwiSaver tax - Geographic breakdown

Below figures are an example of how a KiwiSaver schemes allocation with respect to growth and income assets look like. 

KiwiSaver Tax - Asset breakdown

 

In most cases, growth assets such as shares, generate more taxable returns as compared to investments in bonds, fixed interest bonds etc. Thus a KiwiSaver scheme with a higher asset allocation to growth assets is likely to incur more tax as compared to a KiwiSaver scheme with more allocation to income investments. 

The amount of tax you will be charged thus will not just depend upon how much of your assets are invested in growth funds but also what proportion of your KiwiSaver funds have asset allocation in international shares.

In the case of New Zealand share there is also no capital gains tax. What this means is that if you today buy shares in a company such as Air New Zealand and their share price triples the next day, you will not be required to pay tax on the returns you make from that price increase. You would only be taxing tax should you receive dividends from said shares. 

Returns made from shares invested in international companies are taxed differently. The FDR (Fair Dividend Rate) method is what is used to calculate the tax applied to international shares that are not listed on the Australian share market (remember, we said shares listed on the ASX are tax free). The method assumes that the international shares will generate a dividend income of 5%. This is applied as a fixed rate which means that no matter whether the share price goes up or down, you only get taxed on 5% of said share value.

Funds with Conservative Assets vs Funds with Growth Assets

Funds with Growth Assets have higher rates of return, and on average give you higher amounts of income. This does not necessarily mean that the tax you will be paying will also be higher. There are benefits to these growth assets. The returns earned on such investments could well make it worth the investors’ while and far exceed the tax they will be paying. After all, there is a reason these growth asset funds are still around. 

The new Financial Markets Authorities regulations on fees are designed to give the investors scale benefits that fund managers themselves receive. The fees that the investors are currently paying are deemed to be too high and the value for money they are receiving is being put into question. The FMA’s aim is to help regulate the market in the investors’ favour by demanding higher returns for the fees the investors are paying to their providers or by having these fees reduced. What does this have to do with tax, you might be wondering.

Well, the new regulations’ purpose is to readjust the fee/returns ratio, while the tax rate rate remains unchanged. Meaning you as the investor might be receiving higher returns and/or paying lower fees to your providers. While the proportion of tax you are paying is directly related to the returns, if you are receiving more value for money from your investments, you would consider the tax you are paying to be worth it. 

This means that although Funds with more Growth Assets do see, on average, higher returns and are taxed more heavily due to those higher returns, the benefits you would be receiving from such a fund could far exceed the ‘setbacks’ of a higher tax. 

Investment managers put a great deal of focus on making their schemes as tax-effective as possible. They are always adjusting the asset ratios in order to achieve the highest returns possible while allowing the investor to minimise the amount of tax they have to pay to the IRD. 

Let’s remember John and his $10,000 KiwiSaver account. For this year he was taxed on all his $500 returns, with let’s say a PIR of 17.5%. Therefore he has $412.5 left to add to his pre-existing $10,000, taking his balance available for investing for the following to $10,412.5. 

Screen Shot 2021-04-29 at 6.42.15 PM

In scenario one this balance earns a 3% return on a Cash Fund composed mostly of investments in Bonds, Term Deposits and other low risk securities. This means that $312 (his return on investment 3% x $10,412.5) is being taxed 28% because Cash Funds have the highest tax rate applied to them. This is due to the high allocation of lower risk securities such as bonds and term deposits. This makes the returns from such a fund much more of a ‘sure’ thing and much more consistent, on average, than returns from other types of funds. 

This leaves him with $225 to add to his total amount for his third year of investing. 

Screen Shot 2021-04-29 at 6.52.13 PM-1

In scenario two he earns a 6% return in a Growth Fund composed mostly of growth assets such as stocks and investment properties. Because he is in a Growth Fund composed mostly of shares and other higher risk securities , his tax rate (even with a PIR of 28%) has gone down to 9%. This is due to the mixture of securities in a Growth fund, i.e. a mixture of tax free New Zealand and Australian shares and other International Shares taxed only at 5%. National Capital has run the calculations and the overall tax John has to pay on his Growth Fund returns comes down to 9%. 

6% of 10,412.5 is ~$625. The tax on that (9%) is equal to $56, leaving him with $569 to add to his total investment amount for his third year of investment. 

Screen Shot 2021-04-29 at 6.44.25 PM

So as you can see, that is nearly double the amount he was left with in scenario one.  

$569 > $225

Being taxed higher rates on schemes with higher growth asset allocations does not necessarily mean you should shy away from said schemes.

 

How Is The KiwiSaver Tax Applied?

In most cases, your KiwiSaver scheme is a Portfolio Investment Entity. A PIE is a type of entity (such as managed funds)  that invests your contributions in different types of investments as shown in an example below;

PIE fund

 Note: For more information on other types of schemes read the additional reading section below. 

The PIE rules allow investment funds to pay tax on your share of investment earnings at your specific Prescribed Investor Rate (PIR) with an upper ceiling tax rate of 28%.

Since the new legislation in 2019, IRD is now able to give direct instructions to PIE managers to change the tax rate should the Commissioner find that the currently applied tax rate is incorrect. This will be based on the information the IRD has about the investor’s income. 

Your share of taxable income changes depending on what kind of fund you are in as well as the asset allocation it has. 

It's Not All About KiwiSaver Tax

It is important to remember that everyone is different and it is the tolerance to risk that is another very important thing to focus on, in addition to tax rates, fees, and returns.
