2. How Does New Zealand Income Tax Work?
New Zealand operates a Pay As You Earn (PAYE) system. When you work as an employee, your employer automatically calculates and deducts income tax and statutory levies from your paycheck each payday and remits them directly to the Inland Revenue Department (IRD).
Unlike countries such as Australia or the United States, New Zealand does not have a general tax-free threshold. Every dollar you earn from $1 onwards is taxed starting at 10.5%. However, tax rates are progressive, meaning you only pay higher rates on the portion of your income that falls into higher thresholds.
3. Marginal Tax Rate vs Effective Tax Rate Breakdown
A common point of confusion is the distinction between your marginal tax rate and your effective tax rate:
- Marginal Tax Rate: The rate of tax applied to the very last dollar of income you earn. For example, if you earn $85,000 per year, your marginal tax rate is 33% because your top dollars fall into the $70,001–$180,000 tax band.
- Effective Tax Rate (Average Tax Rate): The actual percentage of your total income paid in tax. Because your first $14,000 is taxed at 10.5%, your next $34,000 at 17.5%, and so forth, your overall effective tax rate is significantly lower than your top marginal rate.

5. New Zealand Tax Codes Explained (M, S, SL, etc.)
When starting employment in New Zealand, you must complete an IR330 Tax Code Declaration form. IRD uses your tax code to determine how your employer calculates pay period tax deductions:
- M (Main): Used for your primary income source (where you earn the majority of your income) if you do not have a student loan.
- M SL (Main + Student Loan): Used for your main job if you have a New Zealand student loan.
- S (Secondary - Low Income): Used for a second job if your total annual income across all jobs is between $14,001 and $48,000 (withheld at 17.5%).
- SH (Secondary - High Income): Used for a second job if total annual income is between $70,001 and $180,000 (withheld at 33%).
- ST (Secondary - Top Rate): Used for secondary income when total income exceeds $180,000 (withheld at 39%).
- NSW (Non-Resident Seasonal Worker): Applies to recognized seasonal employer (RSE) workers (flat 10.5%).
6. ACC Earners' Levy & Statutory Deductions
In addition to income tax, all employees in New Zealand pay the Accident Compensation Corporation (ACC) Earners' Levy. ACC provides comprehensive no-fault personal injury coverage across New Zealand.
The ACC Earners' Levy is automatically deducted alongside PAYE tax at a rate of 1.60% (inclusive of GST) up to a maximum liable income cap (e.g. capped at $142,283 of earnings).
7. What is Residual Income Tax (RIT)?
Residual Income Tax (RIT) is the amount of income tax you owe after deducting tax credits (such as foreign tax credits, donation tax credits, or tax already paid at source via PAYE).
If your RIT exceeds NZD $5,000 at the end of a tax year, you may be required to pay Provisional Tax in installments across the subsequent tax year.
