Company Tax and Imputation Calculator

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.
