Choosing the right PAYE tax code NZ is important because it helps your employer deduct the appropriate amount of tax from your salary or wages. Your tax code can depend on your employment situation, expected income, student loan status and eligibility for certain tax credits.

If you are starting a new job, working for multiple employers or reviewing your payslip, understanding your PAYE tax code in New Zealand can help you identify when your details may need updating. This guide explains common tax codes, secondary tax and how to check your code using official Inland Revenue (IRD) resources.

1. What is a PAYE tax code in NZ?

A PAYE tax code in NZ tells your employer or income payer how to calculate tax deductions from your salary or wages. PAYE stands for Pay As You Earn, and the deductions are paid to Inland Revenue.

Your tax code is different from your income tax rate. Your tax rate determines how your taxable income is taxed, while your tax code helps your employer calculate deductions from a particular income source.

New Zealand’s individual tax year runs from 1 April to 31 March. When checking your PAYE tax code in 2026, use current IRD guidance rather than relying on outdated tax-code charts.

2. Common PAYE tax codes in NZ explained

Understanding common PAYE tax codes in NZ can help you identify which code may apply to you. The following table provides general explanations. Always check the official requirements before selecting your code.

This is a general guide, not a personalised tax-code determination. Check the official IR330 tax code declaration for current requirements.

3. How to choose the right PAYE tax code NZ

If you are unsure which PAYE tax code NZ applies to you, follow these steps and confirm your selection with Inland Revenue.

Step 1: Identify your main source of income

Consider your main or highest source of salary or wage income. If you have multiple jobs, you may need a main-income code for one job and a secondary tax code for another.

Step 2: Estimate your annual income

Estimate your income for the full tax year, from 1 April to 31 March. Your expected annual income may affect which secondary tax code applies to an additional job.

Step 3: Check your student loan status

If you have a New Zealand student loan, you may need a code with the SL suffix so the relevant student loan deductions are made. If you repay your loan in full or your circumstances change, check whether your code needs updating.

Step 4: Check eligibility for the ME tax code

The ME tax code relates to the Independent Earner Tax Credit. Eligibility depends on Inland Revenue’s requirements, including income and other conditions. Do not choose ME based on your salary alone.

Step 5: Complete your IR330 declaration

Once you have identified the appropriate code, complete the IR330 tax code declaration and give it to your employer or income payer. If your circumstances change, review whether you need to submit an updated declaration.

Read IRD’s instructions for completing a tax code declaration.

4. What is a secondary PAYE tax code in NZ?

A secondary PAYE tax code in NZ may apply when you receive salary or wages from more than one job at the same time. For example, you might have a full-time job and a part-time job or receive another type of payment alongside your main employment income.

Secondary tax deductions help account for income from an additional source. The correct secondary code depends on your estimated annual income and Inland Revenue’s rules.

Common secondary tax codes include SB, S, SH, ST and SA. The appropriate code is not necessarily the same for everyone with a second job. Student loan obligations may also affect the deductions that apply.

Secondary tax is a withholding method. It does not mean your second job is automatically taxed twice. Your final tax position depends on your overall taxable income and the applicable tax rules.

Read IRD’s guidance on secondary tax codes.

5. What happens if you use the wrong PAYE tax code?

Using the wrong PAYE tax code in NZ can cause too much or too little tax to be deducted from your pay. This may affect your take-home pay and could contribute to a tax bill or refund after Inland Revenue assesses your income.

You may need to review your tax code if you:

• Start a second job or change your main job.
• Take out or repay a student loan.
• Experience a significant change in expected annual income.
• Become eligible or no longer eligible for a tax credit.
• Start receiving another type of taxable payment.

If you think your tax code is incorrect, review the official IRD instructions and provide your employer with an updated IR330 declaration if required. If you regularly receive a large tax bill or refund, ask Inland Revenue whether a tailored tax code is appropriate for your circumstances.

6. What happens if you do not provide a tax code?

Employees should provide the required tax code declaration to their employer. If an employee does not provide the declaration, the employer must generally apply the non-notified rate of 45%, plus the applicable ACC earners’ levy, under the relevant rules.

This can significantly reduce your take-home pay. If you have not submitted your declaration, contact your employer and follow Inland Revenue’s instructions promptly.
