How PAYE is calculated in New Zealand
PAYE (Pay As You Earn) is how Inland Revenue collects income tax from salary and wage earners. Your employer withholds PAYE from each pay and forwards it to IRD. The PAYE amount on your payslip combines several pieces:
- Income tax calculated on your annualised gross income using NZ's progressive brackets (10.5% / 17.5% / 30% / 33% / 39%)
- ACC earner's levy at 1.67% on income up to $152,790 per year
- Student loan repayments (12% on income above the threshold) if your tax code ends in "SL"
- KiwiSaver at your chosen rate (3% / 4% / 6% / 8% / 10%) — separate from PAYE but deducted from the same pay
Primary vs secondary tax codes
If you only have one job, you use a primary code (M, ME, M SL, or ME SL). Income tax is calculated using the progressive brackets — each dollar is taxed at the rate of the bracket it falls into.
If you have a second job, that job uses a secondary code (SB, S, SH, ST, or SA — plus "SL" if you have a student loan). Secondary codes withhold a flat rate matched to the marginal bracket your combined income falls into. This is because your primary employer has already used up your lower brackets.

Frequently asked questions
What does PAYE stand for?
PAYE stands for Pay As You Earn. It's the income tax (and student loan, if applicable) your employer withholds from each pay and forwards to Inland Revenue on your behalf.
Is PAYE the same as income tax?
PAYE is the mechanism by which income tax is collected from salary and wage earners. It includes income tax and the ACC earner's levy, and may also include student loan repayments if your tax code ends in 'SL'. KiwiSaver is deducted alongside PAYE but is separate.
Why is my PAYE different each pay period?
If your gross pay varies (overtime, bonuses, irregular hours), the PAYE withheld will vary too. PAYE is calculated by annualising your current pay period's gross, applying the progressive brackets, then dividing back. So a higher pay period pushes more income into a higher bracket for that period.
How is PAYE calculated on a bonus?
Bonuses use 'extra pay' rules with their own withholding rates based on your annualised income. We have a dedicated bonus tax calculator that handles this.
What if I have two jobs?
Your second job uses a secondary tax code (SB, S, SH, ST, or SA — plus 'SL' if you have a student loan). Pick the secondary code based on your TOTAL income from both jobs. The flat rate matches the marginal bracket your combined income falls into.
How do I check my employer is deducting the right amount?
Enter your gross pay per period and your tax code into this calculator. The PAYE figure should match your payslip within a dollar or two. If it's more than a few dollars off, raise it with your payroll team — they may have your code wrong.
What happens if I'm on the wrong tax code?
You'll either over- or under-pay tax during the year. IRD performs an automatic income tax assessment after 31 March each year. Overpayment → refund; underpayment → bill. Using the right code from day one avoids surprises.
Does PAYE include KiwiSaver?
No. KiwiSaver is a separate deduction your employer takes alongside PAYE. This calculator can include it as an optional add-on so you see your true take-home.
Does PAYE include ACC?
Yes — the ACC earner's levy (1.67% in 2025-26, capped at $152,790) is collected through PAYE alongside income tax.
When is PAYE paid to IRD?
Your employer pays PAYE to IRD by the 20th of the month following the pay period (or twice monthly for larger employers). You don't need to do anything — it's automatic.
