TL;DR: The lowest income tax rate NZ individuals currently pay is 10.5% on the first $15,600 of taxable income. The rates applying from 1 April 2025 are progressive: each rate applies to the income within its own band. These are individual income tax rates, not a complete measure of every deduction or levy.
- The lowest current individual rate is 10.5%.
- Higher rates apply only to the income within their bands.
- Business structure and other obligations affect the overall position.
A tax bracket can sound more alarming than it is. Moving into a higher bracket does not mean all your income is suddenly taxed at the higher rate. Only the portion within that band is affected.
For a business owner, the next distinction is between turnover, profit and personal taxable income. Those are different amounts, and the way income reaches you depends on the business structure. A correct rate applied to the wrong number still gives an unhelpful answer.
What are the current individual income tax bands?
Inland Revenue lists the following bands from 1 April 2025. The first $15,600 is taxed at 10.5%, the portion over $15,600 to $53,500 at 17.5%, over $53,500 to $78,100 at 30%, over $78,100 to $180,000 at 33%, and the portion over $180,000 at 39%.
These figures describe the standard individual income tax schedule. A final calculation may also involve credits, deductions or other obligations. Inland Revenue's current rate table and calculator are the appropriate references for checking a calculation.
Key point: The published bands apply progressively, rather than one rate applying to all income.
What is the difference between marginal and average tax?
Your marginal rate describes the rate applying to the next dollar within the relevant band. Your average income tax rate describes total income tax as a proportion of the taxable income being measured.
The two are different because the earlier portions of income remain in their lower bands. This distinction matters when considering extra work or a change in income. The calculation should show the additional return after the relevant tax and costs, rather than assume the highest band applies to everything.
Key point: Marginal and average rates answer different questions about the same income.
How does this relate to sole trader income?
For a sole trader, business income needs to be worked through the tax calculation with the appropriate expenses and adjustments. The amount withdrawn from the bank account is not a substitute for that calculation.
Other personal income may also need to be included. Your accountant can help estimate the total position and the amount to reserve. A regular provision can make the eventual payment easier to manage, but the percentage needs to suit your circumstances rather than come from a universal rule.
Key point: The tax estimate needs the full taxable position, rather than only drawings or sales.
What should you do before relying on a tax figure?
A useful check confirms the tax year, the type of income and whether the calculation covers income tax only. ACC, student loan obligations and other items may need separate consideration, depending on the person.
Your forecast also needs payment timing. Knowing an annual estimate does not ensure the money will be available when required. A practical tax process connects the estimate, the reserve and the due dates, with a review when income changes materially.
Key point: A useful tax estimate needs the correct period, scope and payment plan.
What information is needed for a useful tax estimate?
A calculation needs the correct inputs as well as current rates. Your accountant can explain which income and adjustments belong in it. The resulting estimate should be connected to the business cash plan so that a future obligation is not mistaken for money available now.
- The relevant tax year is identified.
- All relevant income sources are considered.
- The scope of the estimate is clear.
- The reserve and payment timing are reviewed when circumstances change.
Key point: The estimate should support a payment plan, rather than remain an isolated annual number.
Which official sources can you check?

Key point: The current official guidance is the reference for a rule or requirement; your own circumstances may need an adviser’s assessment.
Frequently asked questions
Is there a general tax-free income band in New Zealand?
The standard individual rate schedule starts at 10.5% rather than a general tax-free band. Credits and individual circumstances can affect the final amount payable.
Does a higher bracket apply to all my income?
No. The progressive schedule applies each rate to the portion of taxable income in that band.
Are these the rates a company pays?
No. This article explains individual rates. Companies can have different treatment, and payments from a company to its owner require separate consideration.
Can this article determine the tax treatment for my situation?
No. This is general information, with links to official guidance checked on 30 October 2026. Your accountant or tax adviser should assess the facts, current rules and any exceptions before you act.
How can I enquire about business coaching?
The Book a Conversation button takes you to the enquiry section. A little information about your business and the issue you want help with lets us suggest an independent coach we think could be a good fit. That coach may work with you remotely rather than be based in your area.
Key point: The next step should suit the question, whether that is a practical business review or advice from a specialist.

What to take away from this
A useful tax estimate needs the correct period, scope and payment plan. The estimate should support a payment plan, rather than remain an isolated annual number.
Where does coaching fit alongside tax advice?
Your accountant or tax adviser should confirm the treatment for your circumstances. Coaching can help you organise the surrounding business work, such as record-keeping responsibilities, cash planning and following through on the decisions you have agreed.
Our collective of independent business coaches works with small business owners remotely as well as across New Zealand. The Book a Conversation enquiry form lets you tell us what you need. We can suggest someone we think will be a good fit, which may be a coach outside your area.
