Important IRD figures every New Zealand employee, sole trader, business owner and KiwiSaver member needs to know this tax year.
No Tax-Free Threshold
Unlike Australia, New Zealand has no tax-free threshold. You pay PAYE income tax at 10.5% from the very first dollar you earn. Low-income earners are supported through Working for Families tax credits instead.
ACC Earner's Levy
All New Zealand employees pay the ACC earner's levy at 1.67% of gross income up to $152,790 for 2025/26. This funds New Zealand's no-fault accident compensation scheme for all residents and visitors.
KiwiSaver
All new employees are automatically enrolled in KiwiSaver. You contribute 3%, 4%, 6%, 8% or 10% of gross pay. Your employer must contribute at least 3%. The government adds up to $521 per year as a member tax credit.
GST Registration
You must register for GST with the IRD when your taxable supplies exceed $60,000 in any 12-month period. Once registered, you add 15% GST to your prices and file GST returns monthly, two-monthly or six-monthly.
Student Loan Repayments
Student loan repayments are deducted automatically through PAYE at 12% of every dollar earned above $24,128 per year. New Zealand student loans are interest-free while you remain in New Zealand.
Independent Earner Tax Credit
The IETC gives eligible New Zealand tax residents up to $520 per year in tax credits if they earn between $24,000 and $70,000 and do not receive Working for Families or other government assistance.

NZ PAYE Tax Calculator: IRD Rates 2025/26
New Zealand uses a Pay As You Earn (PAYE) system where your employer deducts income tax from your wages or salary before paying you, based on your tax code. The PAYE system means most New Zealand employees never need to file an income tax return, as their tax obligations are automatically met throughout the year through payroll deductions.
New Zealand income tax is progressive, with five brackets ranging from 10.5% to 39%. A key difference from countries like Australia is that New Zealand has no tax-free threshold. Every dollar you earn is subject to income tax from the first dollar at 10.5%. For example, on a salary of $55,000, you pay 10.5% on the first $15,600, 17.5% on income from $15,601 to $53,500, and 30% on the remaining $1,500, giving an effective tax rate of around 15.9%.
In addition to PAYE income tax, all employed New Zealanders pay the ACC earner's levy, which is currently 1.67% of gross income up to the $152,790 cap for 2025/26. This levy funds the Accident Compensation Corporation scheme, which provides no-fault cover for personal injuries to all New Zealand residents and visitors.
NZ GST Calculator: Add or Remove 15% GST
New Zealand's Goods and Services Tax (GST) is a flat rate of 15% applied to most goods and services. GST was introduced in New Zealand in 1986 at 12.5% and increased to 15% in 2010. Unlike VAT systems in some countries, New Zealand GST applies broadly with very few exemptions. Financial services, residential rent and some donated goods sold by non-profit organisations are among the limited GST-exempt supplies.
To add 15% GST to a net price, multiply by 1.15. For example, $100 multiplied by 1.15 equals $115 including GST. To remove GST from a gross price, the IRD prescribes using the 3/23 fraction method. Divide the gross amount by 23, then multiply by 3. For example, $115 multiplied by 3/23 equals exactly $15 GST. You must register for GST when your taxable supplies exceed $60,000 in any 12-month period.
KiwiSaver Calculator: Grow Your Retirement Savings
KiwiSaver is New Zealand's voluntary workplace-based savings scheme designed to help Kiwis save for retirement or a first home. All new employees are automatically enrolled and must actively opt out if they do not wish to participate. You can choose to contribute 3%, 4%, 6%, 8% or 10% of your gross salary, and your employer must contribute at least 3% on top of your salary.
The government adds a member tax credit of 50 cents for every dollar you contribute, up to a maximum of $521.43 per year. To receive the full government contribution, you need to contribute at least $1,042.86 per year. KiwiSaver funds are locked in until age 65 or NZ Super age (whichever is later), though first home buyers can make an early withdrawal for a deposit, and those experiencing significant financial hardship may apply for a withdrawal.
NZ Mortgage Calculator: Home Loan Repayments
New Zealand home loans are typically offered as one to five year fixed rate terms or as floating (variable) rate loans. Fixed rates provide certainty of repayments for the term but may attract break fees if you repay early or refinance. Floating rates move with the Reserve Bank of New Zealand (RBNZ) official cash rate (OCR) and can be repaid or refinanced at any time without penalty.
Most New Zealand lenders require a minimum deposit of 20% for an owner-occupied property, though first home buyers may be able to access lending with a deposit as low as 5% through the First Home Loan scheme backed by Kainga Ora. Making fortnightly repayments instead of monthly repayments is a popular NZ strategy to pay off your mortgage faster, as you effectively make one extra full monthly payment per year.
NZ Student Loan Repayment Calculator
New Zealand student loans are interest-free for borrowers who remain in New Zealand. Repayments are automatically deducted through the PAYE system at a rate of 12% on every dollar earned above the annual repayment threshold of $24,128 for 2025/26. For example, if you earn $50,000, your annual student loan repayment is 12% multiplied by ($50,000 minus $24,128), which equals $3,105 per year or approximately $119 per fortnight.
If you leave New Zealand for more than 6 months, interest applies to your student loan at the current rate set by the IRD. Making voluntary repayments above your required amount of $500 or more previously attracted a 10% bonus from the government, though this incentive has been modified in recent years. Contacting the IRD or checking your myIR account gives you the most accurate current repayment information for your specific loan balance.
