Company Tax and Imputation Calculator NZ

This calculator works out New Zealand company tax on your profit at the 28 percent rate, the after-tax profit left to distribute, and the imputation credits that attach to a fully imputed dividend. It is a useful tool for company owners and shareholders who want to understand how profit flows from the company to their own pocket and how the imputation system stops the same money being taxed twice. A company pays 28 percent tax on its taxable profit, leaving 72 percent as after-tax profit it can retain or pay out as dividends. When it pays a fully imputed dividend, it attaches imputation credits equal to the tax already paid, which the shareholder then uses against their own tax on that dividend, so they are only ever taxed once on company profits, topping up to their personal rate if it is higher than 28 percent. You enter your company profit, and the calculator shows the company tax, the after-tax profit available, and the maximum imputation credits you can attach when distributing it. Use it for provisional tax planning and to understand the building blocks before working out the shareholder tax with the dividend gross-up calculator. This is general information about the imputation system, not tax advice, so confirm the detail with your accountant.

Assumes the 28% company rate and that profit is fully taxed. Imputation credits attach when fully imputed dividends are paid. General information, not tax advice.

How it works

The company tax is the taxable profit times 28 percent. The after-tax profit is the remaining 72 percent, which is what the company can retain or distribute. The imputation credits available equal the company tax paid, since those credits can be attached to dividends to pass on the tax already paid to shareholders.

Worked example

On 100,000 dollars of profit, company tax is 28,000 dollars, leaving 72,000 dollars of after-tax profit. If all of it is distributed as a fully imputed dividend, it carries 28,000 dollars of imputation credits.

Frequently asked questions

What is the company tax rate in New Zealand?

The company tax rate is 28 percent of taxable profit. A company pays this on its profit and can then distribute the after-tax profit to shareholders as dividends, attaching imputation credits for the tax already paid.

What are imputation credits?

Imputation credits represent the company tax already paid on profits. When a fully imputed dividend is paid, shareholders receive credits equal to that tax, so the same profit is not taxed twice. Shareholders use the credits against their own tax on the dividend.

Does the shareholder pay more tax?

It depends on their rate. A shareholder on 33 or 39 percent pays the difference above the 28 percent already paid, while one on a lower rate may have excess credits. Use the dividend gross-up calculator to see the shareholder side.
