NZ Company Tax Rate Explained for Business Owners

The current NZ company tax rate is 28%, and it has applied since the 2011-12 income year. That figure matters, but it doesn’t tell you what will ultimately reach your personal bank account, because imputation credits, shareholder tax and provisional tax timing all change the cash outcome.

You’re sitting in an Auckland café reviewing your year-end accounts. Revenue looks healthy, but the tax invoice still stings. The immediate question is usually, “If my company pays 28% tax, how much of the profit can I use?”

The answer depends on taxable profit, not revenue, how much money stays in the company, whether profits are distributed, and your personal tax position. The company is one taxpayer. You, as the shareholder, may have another tax bill when money comes out. Understanding the connection is more useful than staring at the headline rate.

What the NZ Company Tax Rate Actually Means for Your Business

A company pays tax on taxable profit after allowable business expenses and tax adjustments, not on every dollar it invoices. Strong sales can still produce modest taxable profit, while a smaller operation with fewer costs may face a larger tax bill.

A company is its own legal and tax entity. It files its return and pays tax on its profit. The shareholder then deals with salary, dividends, or other amounts received from the company. Those payments may create personal tax consequences after the company has paid tax.

Practical rule: Don’t treat the company bank balance as personal income. Check whether the money is retained profit, shareholder drawings, salary, GST, or tax set aside for Inland Revenue.

The 28% NZ company tax rate is the starting point for understanding the owner’s final tax position. Imputation credits can pass company tax through to shareholders, while provisional tax affects when cash leaves the business. Looking only at the headline rate misses how these pieces connect.

Before taking money from the company, identify what it represents and how it will be taxed personally. A salary, dividend, shareholder drawing, and retained profit can produce different outcomes, even when they come from the same company bank account. That check helps prevent unexpected shareholder tax and cash-flow pressure.

Current Rate and How It Compares Over Time

Most New Zealand companies pay 28% company tax, with Inland Revenue showing this as the main business rate alongside a separate 17.5% rate for Māori authorities. The 28% company rate has applied since the 2011-12 income year, after legislation reduced it from 30%. For investments through multi-rate PIEs, the 28% top rate applied from 1 October 2010, making the 2010-2012 period an important structural change in how company and managed-fund taxation operated. Inland Revenue’s business tax-rate guidance sets out the current framework.

New Zealand’s rate has been much less stable over its longer history. Trading Economics records an all-time high of 48.00% in 1986, a record low of 28.00% in 1988, and a long-run average of 32.91% from 1981 to 2026. Inland Revenue tax-policy material also places New Zealand’s rate at ninth highest in the OECD in 2025, compared with an OECD unweighted average of 24%.  

For an Auckland owner, the practical point is clear. New Zealand’s rate is familiar domestically but sits above the average of peer economies, so imputation credits and profit-distribution planning matter. A company that retains profit, pays dividends, or funds an investment will produce different personal cash outcomes.

How Imputation Credits Pass Tax Benefits to Shareholders

Imputation prevents the same profit being taxed twice. A company earning $100,000 of taxable profit pays $28,000 in company tax, leaving $72,000 available for a fully imputed dividend.

The shareholder receives $72,000 in cash and $28,000 of imputation credits. Together, those amounts create $100,000 of gross taxable income. The credit records company tax already paid, so the shareholder is assessed on the combined amount rather than paying tax as though the company tax had never been paid.

At a 33% marginal tax rate, tax on that gross income is $33,000. The $28,000 imputation credit offsets most of the liability, leaving $5,000 of top-up tax for the shareholder. Company tax therefore works as a prepayment against personal tax, not as a separate tax cost that disappears. The Inland Revenue explanation of imputation credit accounts explains how companies record tax paid and dividend credits in the imputation credit account, or ICA.

The maximum imputation ratio is 28 cents of credit for each $1 of gross dividend paid.

A shareholder on a marginal rate below 28% may have no further tax to pay, or may receive a refund, subject to the wider tax rules. Before approving a dividend, review this guide to understanding imputation credits and check the company’s ICA balance.

Provisional Tax Dates and Cash Flow Planning

Provisional tax catches owners because the payment schedule doesn’t always match the month profit arrives. A March balance-date company generally pays instalments on 28 August, 15 January and 7 May, Your exact obligations can differ, so check myIR.

The first instalment can arrive before the previous year’s tax return has been filed. That creates a common cash squeeze. December and January can already be expensive months for wages, suppliers and holidays, while the second provisional-tax payment still falls due.

A workable cash routine

Use a separate tax savings account and transfer money into it whenever customers pay you. The amount should reflect your expected taxable profit and existing tax commitments, not an arbitrary percentage of revenue. Keep GST and tax money separate from operating cash so a busy trading account doesn’t disguise what belongs to Inland Revenue.

The standard method uses prior tax information, while estimation can be appropriate when current-year profit has changed materially. Estimation needs care. Underpaying can create use-of-money interest, while overestimating can tie up working capital unnecessarily.

For a practical explanation of the calculation and payment process, see this guide to provisional tax in New Zealand. The best plan is boring but effective, forecast profit early and reserve cash before the due date appears.

Worked Example of Company Tax in Action

Take a small Auckland service business with $120,000 of profit before owner tax. The structure changes how tax is paid and when the owner can access the money.

The company pays $33,600, leaving $86,400 available for retention or distribution. If distributed with available imputation credits, the shareholder includes the dividend and credit in their personal tax calculation. The company structure may let the owner leave some profit inside the business for working capital or future investment.

The sole trader reports the $120,000 directly as personal business income. Personal marginal rates apply across the relevant portions of income, so the result depends on the owner’s other earnings and deductions.

Neither structure wins automatically. A company can help separate business and personal affairs and defer personal tax on retained profit, but it brings more records and compliance. A sole trader is often easier to administer, particularly where the owner needs most of the profit personally. Choose based on cash needs, reinvestment plans, risk, and the value of ongoing advice, not the 28% figure alone.

Frequently Asked Questions About NZ Company Tax

Does every company pay 28%?

Most companies pay the 28% rate. Special rules and limited exceptions can apply, including qualifying charities and particular entity types, so confirm the position before filing.

How does PAYE work if I pay myself a salary?

A salary is generally treated differently from a dividend. The company must deal with PAYE obligations, while the owner returns the salary as personal income. Get the payroll treatment right before making regular transfers.

What happens to imputation credits held by a family trust?

The outcome depends on the trust, its beneficiaries and how the dividend is distributed. Keep clear dividend and credit records, then have the trust’s tax position checked before declaring the payment.

Can company losses reduce my personal income?

Generally, no. A company’s loss belongs to the company and doesn’t usually offset a shareholder’s personal income, unlike the different treatment that can apply to a look-through company (LTC).

When should I move from sole trader to company?

Consider it when you’re retaining profit, bringing in shareholders, managing commercial risk, or need a clearer structure for growth. Don’t incorporate solely because 28% looks lower, because personal tax and compliance still matter.

Is GST the same as company tax?

No. GST registration and company income-tax obligations are separate issues. A business can face one, both, or neither depending on its circumstances, so don’t use a GST decision to determine your company structure.
