New Zealand Tax Interest Rate Changes:
What You Need to Know
Effective 16 January 2025, Inland Revenue has adjusted the interest rates applied to tax overpayments and underpayments. These changes affect all taxpayers, including individuals, sole traders, and businesses.
Here’s a comprehensive breakdown of the new tax interest rates, their implications, and practical advice to navigate the updates.
New Tax Interest Rates Explained
Tax Underpayment Interest Rate:
Taxpayers who underpay taxes will incur an interest rate of 10.88%, down slightly from the previous 10.91%.
This interest rate applies when taxes are not paid by the due date and is intended to encourage timely payments.
Tax Overpayment Interest Rate:
For taxes that are overpaid, the interest rate will be 4.3%, reduced from 4.67%.
This reflects the lower return taxpayers can expect on overpaid amounts held by Inland Revenue.
Context Behind the New Zealand Tax Interest Rate Changes
The adjustments align with Inland Revenue’s formulas:
- The underpayment rate is based on the Reserve Bank’s floating first mortgage rate for new housing customers, plus 2.5%.
- The overpayment rate is set as the greater of 0% or the Reserve Bank’s 90-day bill rate minus 1%.
These formulas ensure that the rates remain responsive to broader economic conditions. The disparity between high underpayment and low overpayment interest rates discourages taxpayers from using Inland Revenue as a de facto banking service.
Practical Advice for Taxpayers
Plan Provisional Tax Payments Wisely:
Sole traders, contractors, and landlords, who often rely on provisional tax systems, should utilise tax pooling services to minimise exposure to underpayment interest.
Engage Early with Inland Revenue:
Businesses struggling with tax debt should contact Inland Revenue or consult a tax professional (such as a Chartered Accountant) to establish manageable repayment plans. Interest will continue to accrue on unpaid amounts, so proactive management is key.
Monitor Your Payments:
Regularly review your tax account to ensure payments align with your liabilities and avoid unnecessary interest charges.
