New Zealand PAYE Calculator (2026–27)

Why payday PAYE is not simply annual tax divided by 12

Inland Revenue’s regular-pay method first annualises the pay period and discards cents from that annualised income. It calculates annual income tax, adds the ACC earners’ levy, subtracts the independent earner tax credit when an eligible ME code is used, and then converts the result through a truncated weekly PAYE amount. Monthly, fortnightly and four-weekly deductions are derived from that weekly amount.

Those required truncation steps can create a small difference between payroll deductions multiplied across a year and a clean annual-tax calculation. This engine follows the published 2026–27 sequence so its result can be checked against IRD’s PAYE deduction tables.

What PAYE includes in this result

The PAYE line combines income tax and the ACC earners’ levy, less IETC when selected. From 1 April 2026 the earners’ levy used in payroll is 1.75% including GST, charged only up to $156,641 of liable earnings and capped at $2,741.22 for the tax year.

The individual income-tax brackets are 10.5% to $15,600, 17.5% to $53,500, 30% to $78,100, 33% to $180,000 and 39% above $180,000. Only the portion inside each bracket uses that bracket’s rate.

M versus ME and the independent earner tax credit

Choose ME only if you are eligible for the independent earner tax credit and use an ME or ME SL tax code. For 2026–27 the full annual credit is $520 from $24,000 through $66,000 of income, then it reduces by 13 cents for each dollar until it reaches zero at $70,000.

Eligibility involves more than income. You generally cannot receive IETC while you or your partner receive Working for Families, or while receiving an income-tested benefit, New Zealand Superannuation, a veteran’s pension or an overseas equivalent. When unsure, leave the calculator on M and check IRD’s eligibility guidance.

Student-loan deductions use payday thresholds

For main employment, the 2027 tax-year student-loan threshold is $24,128 a year. IRD publishes equivalent thresholds of $464 weekly, $928 fortnightly, $1,856 four-weekly and $2,010.66 monthly. The deduction is 12% of pay above the relevant threshold after gross pay is floored to whole dollars.

This switch models M SL or ME SL regular main-employment pay only. Secondary income, special deduction rates, repayment deductions from bonuses, overseas borrower obligations and voluntary extra repayments need separate treatment.

KiwiSaver and the cash-versus-saving chart

From 1 April 2026 the default employee rate and compulsory employer minimum are both 3.5%. Employees can normally choose 3.5%, 4%, 6%, 8% or 10%; an approved temporary rate reduction can use 3%. The comparison chart shows the immediate take-home difference across contribution rates without pretending the highest cash result is automatically the best financial choice.

Employer contributions are shown separately because they do not form part of take-home pay. ESCT is deducted before the net employer amount reaches KiwiSaver. This calculator assumes the employer contribution sits on top of salary; a total-remuneration package can produce a different payslip and employer-cost result.

Important scope and payslip differences

This calculator covers regular main-employment salary or wages under M, ME, M SL and ME SL. It does not calculate secondary tax codes, tailored tax codes, casual agricultural or election-day work, schedular payments, bonuses and lump sums, child support, payroll giving, benefits, allowances, holiday-pay complications or multiple jobs.

It is an independent educational estimator, not payroll software and not affiliated with Inland Revenue, ACC or a KiwiSaver provider. Your employer’s actual payroll record remains authoritative because pay composition, tax-code declarations, contribution holidays, age eligibility and prior-year ESCT information can alter a real deduction.
