Student Loan Repayment on $180,000 Income (NZ)

What this means at $180,000

Of your $180,000 gross income, $155,872 sits above the $24,128 threshold. At 12%, that produces $18,705 of repayment per year — roughly 10.4% of your total income.

This runs in parallel with your regular PAYE and ACC earner's levy. On a $180,000 salary your total deduction stack (at a main tax code M SL) is PAYE + 1.75% ACC + 12% student loan above threshold — before any KiwiSaver.

At this income level, if you want to clear the loan faster, consider switching to a higher deduction rate via myIR — you can opt in to a rate above 12% so IRD takes more per pay. Or make voluntary lump-sum repayments around bonus or tax-refund time.

If you are planning to move overseas, note that the overseas-based borrower schedule replaces the 12%-above-threshold rule with a fixed annual amount based on your loan balance. On balances above $45,000, that means $5,000+/year even on zero NZ income.

2025-26 vs 2026-27

The repayment threshold is frozen at $24,128 across both 2025-26 and 2026-27 per Treasury's Budget 2025 student loan paper — no CPI indexation until further legislative review. The 12% rate is unchanged since the Student Loan Scheme Act 2011. On $180,000 your annual repayment is therefore the same in both years: $18,705.
