KiwiSaver ESCT and government contribution: the 2026 numbers
By GrowThenDraw Editorial Team · Updated July 28, 2026 · 11 min read · Editorial policy
Four flows can build an employed member's KiwiSaver balance: their payroll deduction, employer money after ESCT, personal direct payments and an eligible government contribution.
Combining them into one percentage hides important tax and eligibility rules. The calculator and this guide keep every component visible.
ESCT is deducted from the employer contribution
Employer superannuation contribution tax normally applies to gross employer KiwiSaver contributions. It is not deducted from the employee's own contribution. The net employer amount invested is the gross contribution minus ESCT.
An alternative PAYE treatment can apply when the employer and employee agree to treat some or all of the employer contribution as salary or wages. That special treatment is outside the calculator.
The 2026 ESCT thresholds
The threshold amount generally combines the employee's salary or wages and gross employer superannuation contributions for the previous tax year. For a person who was not employed for that whole year, the employer estimates the current-year total.
The rate is set at the start of the tax year and normally does not change merely because pay changes during that year. A public calculator without payroll history can therefore estimate the threshold but cannot certify the employer's rate.
- $0 to $18,720: 10.5%.
- $18,721 to $64,200: 17.5%.
- $64,201 to $93,720: 30%.
- $93,721 to $216,000: 33%.
- $216,001 and above: 39%.
Worked example at an $80,000 salary
At the 3.5% employee rate, the member contributes $2,800 per year before payday rounding. A 3.5% gross employer contribution is also $2,800.
Salary plus gross employer money is $82,800, inside the 30% ESCT band. Estimated ESCT is $840, so $1,960 of employer money reaches the account. If the member meets the government conditions and contributes throughout the full member credit year, another $260.72 can be added.
How the $260.72 government maximum is earned
The current rate is 25 cents for each dollar the member contributes between 1 July and 30 June, up to $260.72. Reaching the maximum requires at least $1,042.86 of the member's own eligible contributions.
Payroll deductions and direct personal payments can count. Employer contributions, prior government contributions and money transferred from an Australian retirement scheme do not count toward the member contribution test.
The $180,000 income limit and age rules
The government contribution is available only when annual taxable income is $180,000 or less and the other conditions are met. The current age range is 16 to 65; turning 16 or 65 part-way through a year can prorate the entitlement.
Joining part-way through a year or ceasing to meet residence conditions can also change the amount. GrowThenDraw models complete eligible years and labels partial-year treatment outside scope.
Use standard projection assumptions without calling them forecasts
The Financial Markets Authority describes government-set return assumptions after fees and tax at a 28% PIR, ranging from 1.5% for defensive funds to 5.5% for aggressive funds. Standard projections also use 3.5% pay growth and 2% inflation.
Those common assumptions help comparisons; they do not predict a provider's result. Actual fees, PIR, market returns and contribution interruptions will change the balance.
