Inland Revenue PAYE Calculator review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

For employers and employees in New Zealand who need an estimate of PAYE withheld from salary or wages, Inland Revenue PAYE Calculator provides a focused web-based calculation. It is free and supports weekly, fortnightly, four-weekly and monthly pay periods, using the applicable tax code. Employers working through several employees can see both individual deductions and a combined total, making it more useful for payroll estimates than a single-person-only tool.

The calculation can incorporate KiwiSaver or complying fund membership and the employee contribution rate, as well as other superannuation scheme membership and the employer’s ESCT rate. Results can be printed or saved. This scope is practical for routine salary and wage estimates, but the calculator is not designed to cover every payroll situation: it excludes extra pays such as redundancy or special bonuses, other lump-sum payments, schedular payments and child support deductions. It also does not account for tailored tax codes or student loan special deduction rates.

Choose it when a straightforward PAYE estimate for regular wages, including calculations across multiple employees, is the main need. Employers dealing with the excluded payment types or deductions should use a process that accounts for those cases rather than relying on this calculator alone. Its free access and specific New Zealand PAYE focus suit small and mid-market employers seeking an estimate; it is less suited to anyone needing broader income-tax calculations or a more extensive payroll calculation tool.
