The New Zealand Student Loan scheme provides government-funded loans to eligible students to help cover the costs of tertiary education, including tuition fees, course-related costs, and living expenses. Once you have finished studying, repayment begins automatically — but the rules and costs depend heavily on where you live. For New Zealand residents who remain in the country, student loans are completely interest-free. This is a significant benefit: the real value of your debt does not grow over time, so every dollar you repay reduces the principal. For the 2024/25 year, repayments are triggered when your income exceeds the repayment threshold of $22,828 per year (equivalent to $439 per week). Once your income crosses this threshold, you automatically repay 12 cents for every dollar earned above it — this deduction is made automatically through the PAYE system by your employer, so most employees never need to think about it. Voluntary extra repayments can be made at any time and are encouraged because there is no interest cost to incentivise faster repayment the way there would be with a commercial loan. However, some borrowers choose to invest surplus income rather than repay their loan early, since the interest-free nature makes the loan effectively free money in real terms. Borrowers who move overseas face a completely different regime. Overseas-based borrowers are charged interest (currently a variable rate that has historically been around 3–6%), and the repayment threshold system does not apply in the same way. Instead, repayment obligations are based on loan balance and set by IR on an instalment basis. Failure to meet repayment obligations while overseas can result in significant penalties and credit issues. The loan balance is written off entirely upon the borrower's death, and Inland Revenue sends an annual statement each year showing the current balance, repayments made, and any interest (for overseas borrowers).
Annual Repayment Obligation = max(0, (Annual Income − Repayment Threshold) × 12%); Weekly Repayment = max(0, (Weekly Income − $439) × 12%)
- 1When you start a new job, complete a tax code declaration (IR330) and select the student loan repayment tax code (SL or SL with another code such as M SL) — this tells your employer to deduct repayments via PAYE automatically.
- 2Each pay period, your employer calculates your gross income and deducts the standard repayment: 12% of the amount earned above the threshold ($439/week or $22,828/year). The deduction appears on your payslip.
- 3If you have multiple sources of income (e.g., two part-time jobs), each employer applies the repayment rate separately. You may need to review whether your total repayments match your actual obligation at year end via your tax return.
- 4At the end of the tax year, Inland Revenue reconciles your total income and repayments. If you have underpaid (common when income from multiple sources is combined), you will owe the shortfall. If overpaid, you receive a refund.
- 5If you wish to repay faster, you can make voluntary repayments directly to IR at any time online, by direct debit, or by increasing your employer deductions. Voluntary repayments are not refundable once made.
- 6If you move overseas, notify IR immediately. You will be switched to the overseas borrower regime, which charges interest. IR will set repayment instalments based on your loan balance.
- 7Each year, IR sends an annual statement showing your opening balance, all repayments received (employer deductions and voluntary), any interest charged (for overseas borrowers), and your closing balance. Check this carefully for accuracy.
Repayments are deducted automatically by employer via PAYE
($45,000 − $22,828) × 12% = $22,172 × 0.12 = $2,660.64 per year. At this rate the loan is repaid in approximately 9–10 years (assuming no further borrowing).
Income below the threshold means zero compulsory repayment, but voluntary repayments can still be made
$18,000 is below the $22,828 threshold, so no compulsory repayment applies. The loan remains interest-free for NZ residents, so there is no financial penalty for not repaying while income is low.
Voluntary repayments reduce the outstanding balance immediately but cannot be refunded
Compulsory: ($60,000 − $22,828) × 12% = $4,461.84. Adding a voluntary $5,000 brings total to $9,461.84, significantly shortening the repayment period.
Overseas borrowers must pay interest; failure to meet IR instalment obligations incurs penalties
$30,000 × 3.5% = $1,050 interest per year. Unlike NZ-resident borrowers, overseas borrowers see their loan grow if repayments do not keep pace with interest.

A student receiving both a StudyLink allowance and a student loan uses the allowance for living costs and borrows only for tuition fees, minimising the total loan balance that will need to be repaid after graduation.
Self-Employed Borrowers
{'title': 'Self-Employed Borrowers', 'body': "Self-employed people do not have an employer to deduct repayments automatically. Instead, they pay provisional tax and student loan repayments at the same time — either under the standard instalment dates (August, January, May) or through IR's estimate or ratio options. They must include student loan repayments as part of their end-of-year income tax return filed through myIR."}
Multiple Employers
{'title': 'Multiple Employers', 'body': 'If you work for two employers simultaneously, each employer applies the 12% repayment rate independently above the weekly threshold. This can result in over-deductions because the threshold is effectively applied twice. At year end, IR reconciles your repayments against your actual obligation and refunds any excess.'}

What is the 2024/25 student loan repayment threshold?
The repayment threshold for the 2024/25 tax year is $22,828 per year, which is equivalent to $439 per week. You pay 12% of your income above this threshold. The threshold is reviewed periodically and adjusted in line with wage growth. This is particularly important in the context of nz student loan repayment calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise nz student loan repayment computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Are student loans interest-free for everyone?
No. Student loans are interest-free only for borrowers who are based in New Zealand. Borrowers who move overseas for more than six months become 'overseas-based borrowers' and are charged interest at a variable rate set annually by the government. The rate has historically ranged from approximately 3% to 6%. This is particularly important in the context of nz student loan repayment calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise nz student loan repayment computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
How is the repayment deducted from my salary?
Your employer deducts repayments automatically alongside your income tax through the PAYE system, provided you use the correct student loan tax code (SL suffix on your code, e.g., M SL or S SL). The deduction is 12% of your gross income above the weekly threshold of $439. You do not need to make any separate payments while employed.
What happens to my student loan if I die?
Your student loan balance is completely written off upon your death. The loan does not form part of your estate and is not passed on to your family or heirs. Inland Revenue requires a death certificate to process the write-off. This is particularly important in the context of nz student loan repayment calculations, where accuracy directly impacts decision-making. Professionals across multiple industries rely on precise nz student loan repayment computations to validate assumptions, optimize processes, and ensure compliance with applicable standards. Understanding the underlying methodology helps users interpret results correctly and identify when additional analysis may be warranted.
Can I make voluntary repayments on top of my compulsory deductions?
Yes. You can make voluntary repayments at any time through myIR online, by direct credit to IR's bank account, by direct debit, or by instructing your employer to deduct extra from your pay. Voluntary repayments reduce your principal directly and help pay off the loan sooner. They cannot be refunded once made.
What happens if I move overseas?
If you leave New Zealand for more than six months, you must notify Inland Revenue. You will be reclassified as an overseas-based borrower, which means interest starts accruing on your loan balance. IR will set repayment obligations based on your balance and income. Failure to meet these obligations can result in late payment penalties and may affect your credit rating in New Zealand.
What tax code should I use on my IR330 form?
If you have a student loan and you earn income from a job, you must add 'SL' to your tax code. For example, if your main tax code is M, your student loan code is 'M SL'. If you have a secondary income, you use your secondary code followed by 'SL'. Using the wrong tax code means your employer will not deduct student loan repayments, creating an end-of-year debt.
Does Inland Revenue send statements showing my loan balance?
Yes. IR sends an annual student loan statement (usually in June or July) that shows your opening balance at the start of the year, all repayments received, any interest charged if you were overseas, and your closing balance. You can also check your current balance at any time through myIR online.
Pro Tip
If you are a NZ resident and have surplus cash, consider making voluntary student loan repayments before investing elsewhere — the guaranteed 'return' of eliminating a debt is risk-free, even though the loan is interest-free. However, if you can earn a higher after-tax return on investments than the value of early repayment, investing may be more effective.
Did you know?
New Zealand made student loans interest-free for domestic borrowers from 1 April 2006, which dramatically increased take-up of the scheme. Before that date, borrowers paid interest at commercial-equivalent rates, meaning many graduates spent years just covering interest before making any meaningful dent in their principal.
