By New Zealand law, the employer required to contribute to their employee’s KiwiSaver account or complying fund at 3% of their gross salary or wage if the employee joined Kiwisaver. However, when you look into your KiwiSaver contribution transaction record as an employee, you may notice the employer contribution amount are less than your employee contribution.

Here is an example, assume your weekly income before tax is $1200, $62400/year.

Without KiwiSaver, your take home pay will be $1200 – 225.77 (PAYE) – 16.68 (ACC) = $957.55.

If you join KiwiSaver and contribute 3%, your take home pay will be $1200 – 225.77 (PAYE) – 16.68 (ACC) – 36 (KiwiSaver) = 921.55 On your KiwiSaver statement, your contribution will be $36. However, your employer contribution will be $25.2, not $36. Why?

The reason is the employer contribution are taxed under Employer superannuation contribution tax (ESCT). Your employer payout extra 3% of your income to KiwiSaver but part of that went to IRD as tax.

You may think why both employer and employee are paying 3%, how come the cash hit my KiwiSaver fund is different? (That was me two days ago)

Let’s break it down in detail. The 3% contribution is calculated based on your income before tax. In our example, the weekly 3% KiwiSaver contribution will be $1200 x 3% = $36. So both employee and employer will pay $36 each into the KiwiSaver Fund.

Here is the tricky part, on employee contribution, it was calculate based on pre-tax income and take out on after-tax income. So the $36 will take out after they deduct PAYE and ACC and that $36 will reach your KiwiSaver fund without IRD take out any more tax.

On the other hand, employer contribution will be taxed under ESCT. So 30% of $36 = $10.80 will go to IRD, and the cash hit your KiwiSaver fund will be 36 – 10.8 = $25.2

Therefore, I was wrong by saying you will have 100% return on your employer contribution. It’s more like 67%-89.5% return. It’s still an unbeatable risk-free guaranteed return and one of the best investment in New Zealand.
