What Happens to KiwiSaver PIE Tax at Retirement Withdrawal in NZ (2026): Is Your Lump Sum Tax-Free?

Withdrawing KiwiSaver at 65? Your lump sum is not taxed again on the way out, because PIE tax was already deducted from earnings every year. Here is the tax detail, and why your PIR still matters right up to retirement.

TL;DR: When you withdraw your KiwiSaver at 65, the lump sum is not taxed again on the way out — tax of $0 applies to the withdrawal itself. That is because your fund's earnings were already taxed every year as PIE income at your PIR (10.5%, 17.5% or 28%). The only tax that matters is that yearly PIE tax, which is why your PIR is worth checking before you draw.

One of the most common questions people ask as they approach 65 is whether Inland Revenue will take a slice of their KiwiSaver when they finally withdraw it. It is a fair worry — many lump sums in life do get taxed at the point you receive them.

KiwiSaver works differently. The tax has already been paid, a little at a time, every year you were invested. This guide explains why the withdrawal itself is tax-free, how the yearly PIE tax worked, why your PIR still matters in your final working years, and what changes if you draw down gradually or retire overseas.

Do I pay tax when I withdraw my KiwiSaver at 65?

In short, no — the withdrawal is not taxed again. Once you reach the age of eligibility, currently 65 (the NZ Super qualifying age), you can withdraw all of your KiwiSaver savings, and any lump sum or amount you take out at retirement is not taxed on the way out ¹².

This catches a lot of people by surprise, because so many other lump sums are taxed when you receive them. KiwiSaver is the opposite: the tax was collected steadily across the years you were invested, not at the finish line.

So if you have a balance of $180,000 in a fund at 65 and you ask your provider to pay it all out, the full balance lands in your bank account. There is no separate withdrawal tax, no exit tax, and nothing to declare as income on the way out ¹. The reason is simple once you see it: the income your KiwiSaver earned along the way was already taxed each year as PIE income, so the taxman has had his turn before you withdraw ¹.

Why your lump sum isn't taxed again on the way out

KiwiSaver funds are Portfolio Investment Entities, or PIEs. A PIE is a special tax structure: instead of the fund paying tax at company rates and you paying tax again when you cash out, the income your share of the fund earns is taxed inside the fund each year, at your personal rate ³.

That yearly tax is the only tax on the growth. Because it has already been applied to the earnings as they accrued, there is nothing left to tax when you withdraw ¹. The lump sum is made up of:

• Your own contributions, which came out of income that was already taxed as wages or salary, and
• Employer and government contributions plus investment earnings, where the earnings portion has already had PIE tax deducted year by year ³.

None of those components creates a fresh tax bill at withdrawal. This is a deliberate design feature, not a loophole — the tax is collected on the earnings as you go, rather than on the way out. The table below shows the two-stage picture.

How PIE tax was already taken along the way

Each year, your provider works out the investment income attributed to you — your share of the fund's interest, dividends and certain gains — and deducts tax on it at your Prescribed Investor Rate (PIR) ³. PIR is the tax rate that applies to your KiwiSaver earnings, and for a New Zealand-resident individual it is one of three rates: 10.5%, 17.5% or 28% ³.

You never had to file or pay this separately. It came out inside the fund, usually deducted from your balance once a year (and whenever you make a full withdrawal). For most people, PIE income is a final tax, so there is nothing further to do.

The rate matters because it is capped below the top personal tax rate. The highest PIR is 28%, which sits below the 33% and 39% top personal income tax rates — one of the reasons a PIE is tax-efficient for many savers ³. If you never told your provider a PIR, or you joined without an IRD number, the default 28% rate applies automatically ³, whether or not it is the right rate for you.

So the "tax-free withdrawal" headline is only half the story. The growth in your balance was taxed — quietly, every year, at your PIR. The question worth asking is not "will I be taxed at withdrawal?" but "was I on the right PIR all those years?"

Does my PIR still matter close to retirement?

Yes — arguably more than ever in your final working years, and into retirement. Your PIR is based on your income over the last two income years (each ending 31 March), and you use the lower of the two qualifying rates ⁶. That two-year rule is exactly why retirees often drop to a lower PIR once their working income stops.

Here is how the rates work for the 2025/26 tax year. The thresholds below took effect on 1 April 2025 ⁴⁵.

Picture someone who earned $70,000 in their final working year, then retired and lived on NZ Super plus a modest drawdown. Once the high-income years roll off the two-year window, their income may fall below the $53,500 threshold — which can move them from 28% down to 17.5%, or lower ⁴⁵⁶. Because you use the lower of the last two years, that drop can apply sooner than people expect.

The catch is that your provider does not change your PIR for you automatically when your income falls. If you retire on a 28% PIR and never update it, you keep paying 28% on your fund's earnings even after your income has dropped — overpaying tax on a balance that may still be largely invested ³. It is worth checking, because the fix takes a few minutes with your provider and can lift your after-tax return for the rest of your life.

To work out which rate fits your situation, our guide on what PIR you should be on walks through the two-year rule with worked examples.

Tax if you leave it invested and draw down gradually

Plenty of people do not take the whole lot at 65. Instead they leave the balance invested and draw a regular income from it — a managed drawdown. The tax treatment here is the same principle, applied continuously.

If you leave your KiwiSaver invested, the balance keeps earning PIE income that continues to be taxed at your PIR (10.5%, 17.5% or 28%), year by year, exactly as it did before you turned 65 ⁷. The periodic withdrawals you take — the income you draw — are not separately taxed ⁷. You are simply moving already-taxed money out of the fund.

So the choice between a lump sum and a gradual drawdown does not change whether you are taxed — only the earnings are ever taxed, via PIE, and never the withdrawals themselves ⁷. What it does change is how much of your balance stays invested and keeps earning (and being taxed on those earnings). For most people the bigger decisions in drawdown are about investment risk, sequencing and how long the money needs to last — not the tax on withdrawals. Our guide to KiwiSaver drawdown options in retirement covers those trade-offs.

One related point on timing: once you turn 65 you are no longer eligible for the government contribution. In your final qualifying year you receive it only for the part-year before your 65th birthday ⁸. That is a withdrawal-and-contributions detail rather than a tax on your lump sum, but it is worth knowing as you plan the year you turn 65.

What about overseas tax if you retire abroad?

This is where the simple picture gets more complicated, and where general information stops being enough. If you become a non-resident or move overseas, the resident PIR rules no longer apply in the same way ⁹.

In broad terms, non-residents must include their PIE income in a New Zealand income tax return, and overseas tax residents are generally treated at the 28% top rate ⁹. On top of that, the country you move to may tax your KiwiSaver or its earnings under its own rules, and any double-tax agreement can affect the outcome. Some countries treat foreign pensions and savings very differently from how New Zealand does.

Because the answer depends on which country you move to, your residency status and the timing of your move, this is not something to settle from a blog post. Smiths Financial does not provide tax or migration advice. This is general information only — if you are planning to retire overseas, please consult an appropriately authorised tax professional, and check your position with Inland Revenue, before you act.

Checking your PIR is right in your final working years

The single most useful thing you can do in the run-up to 65 is confirm your PIR is correct, because it is the only tax that actually touches your KiwiSaver. A wrong rate does not show up as a bill or a payslip line — it just quietly shaves your returns each year.

01. Find your last two years' taxable income. Pull the figures for the two income years ending 31 March — your IRD income summary or payslips will have them ⁶.

02. Run both years against the thresholds. Apply the 2025/26 brackets to each year separately, using the two figures: taxable income, and taxable income plus PIE income ⁴⁵.

03. Use the lower qualifying rate. If the two years point to different rates, you use the lower one — which often helps people whose income has just dropped at retirement ⁶.

04. Tell your provider. You update your PIR with your KiwiSaver provider, not IRD. Most can change it in the app or online banking in a few minutes ³.

05. Re-check after you stop working. Once your high-earning years roll out of the two-year window, you may qualify for a lower PIR — so it is worth checking again a year or two into retirement ⁶.

Frequently asked questions

Is my KiwiSaver lump sum tax-free when I withdraw it at 65? Yes — the withdrawal itself is not taxed again. The earnings in your fund were already taxed each year as PIE income at your PIR, so there is no separate tax when you take a lump sum at retirement ¹².

If the withdrawal is tax-free, what was I actually being taxed on? The investment earnings your balance made each year. Your provider deducted tax on those earnings inside the fund at your PIR — 10.5%, 17.5% or 28% — usually once a year. That yearly PIE tax is the only tax on KiwiSaver growth ³.

Do I pay tax if I leave it invested and draw an income instead of a lump sum? The balance keeps earning PIE income that is taxed at your PIR while it stays invested, but the regular withdrawals you take are not separately taxed ⁷. Only the earnings are ever taxed, never the withdrawals themselves.

Will my PIR change automatically when I retire? No. Your provider does not adjust it for you. Because your PIR uses the lower of your last two income years, you may qualify for a lower rate once your working income stops — but you have to tell your provider to update it ³⁶.

What happens to my KiwiSaver tax if I retire overseas? The resident PIR rules no longer apply in the same way. Non-residents generally include PIE income in a New Zealand income tax return and may be treated at the 28% rate, and the country you move to may tax it too ⁹. Get tailored tax advice before you move.

Do I still get the government contribution in the year I turn 65? Only for the part-year before your 65th birthday. After you turn 65 you are no longer eligible for the government contribution ⁸.
