New Zealand · 2027 tax-year estimate
Compare the income tax paid during the year with an estimate of your final income-tax liability. Add eligible non-business expenses and IETC when they apply to see a possible refund or amount of tax to pay.
Tax year: 1 April 2026 to 31 March 2027
Estimated refund
$279.50
The income tax entered is higher than the estimated final income-tax liability.
This simplified estimate does not model Working for Families, donation claims, overseas tax credits, PIE adjustments, business or rental income, automatic write-offs, or other individual adjustments.
Estimate only: Inland Revenue issues the official income tax assessment. Check all income and deduction information in myIR before confirming an assessment or filing a return.
The calculator applies the current progressive income-tax brackets to income after entered eligible expenses. It subtracts IETC only when selected, then compares the estimated liability with total income tax already paid.
Open your Income tax account, choose Income summary and download or view Income details. Use total income before the expenses entered here and the total tax paid figure. Do not use the larger PAYE total: PAYE includes the ACC earners' levy.
This is a transparent comparison rather than a promise that a refund is available. For example, $75,000 of income and $15,000 of tax paid produces an estimated refund of $279.50 before other adjustments.
Subtract only eligible non-business expenses entered, without allowing expenses to reduce income below zero.
Apply the current tax brackets and, when selected, the independent earner tax credit.
Tax paid above the estimate produces a possible refund; tax paid below it produces a possible bill.

The calculator can apply a full year of IETC based on the entered income, but the switch does not test every eligibility rule or partial-year entitlement. Do not select it solely because your income falls inside the configured range; Working for Families and some payments can affect eligibility.
IRD permits limited claims for people whose income is already taxed, including some tax-return preparation costs, qualifying income-protection insurance and certain investment-related costs. Keep supporting records and confirm that a cost is eligible before entering it.
Wrong tax codes, multiple jobs, lump sums, interest, dividends, PIE income, overseas income, Working for Families, write-offs and changes reported after calculation can all alter an assessment. Complex business, rental or overseas situations need a complete return calculation.
The calculation uses the tax settings held in KiwiTools’ dated configuration. Inland Revenue remains the source for your recorded income, deductions, eligibility and final assessment.
It subtracts eligible non-business expenses from the total annual income entered, calculates income tax using the current brackets, applies full-year IETC when selected, and compares the result with income tax already paid. A positive difference is shown as an estimated refund and a negative difference as estimated tax to pay.
In myIR, open your Income tax account and select Income summary. The detailed Income details information separates total income, total tax paid and the ACC earners’ levy. Enter total tax paid here, not PAYE, ACC, KiwiSaver or student-loan deductions.
If Inland Revenue has all the information needed for an automatic income tax assessment, the assessment shows whether you have a refund, tax to pay or a balanced position. Any refund is paid using the bank-account details held by Inland Revenue.
No. This calculator compares income-tax liability with total income tax paid. Use the total tax paid figure from your detailed myIR Income details information and do not enter the larger PAYE amount or add ACC, KiwiSaver or student-loan deductions.
IRD allows limited non-business expenses in eligible circumstances, such as some tax-return preparation costs, qualifying income-protection insurance, certain investment-related costs and late-payment interest paid to IRD. Only enter expenses you can support and that IRD permits.
No. The official result comes from Inland Revenue. Working for Families, overseas income and tax credits, PIE income, donation claims, business or rental activity, incorrect tax codes, write-offs and other adjustments can materially change the result.
Check the official process after using the estimate: find your assessment in myIR, understand the payment timing and make sure your tax code is still suitable.
