Dividend Imputation Gross-Up Calculator

This calculator grosses up an imputed New Zealand dividend so you can see the real pre-tax value, the tax due at your marginal rate, and whether you owe extra tax or have credits to spare. Dividends from New Zealand companies usually come with imputation credits attached, representing the 28 percent company tax already paid on the profits behind them. To work out your own tax correctly you cannot just look at the cash you received; you add the imputation credit back on to find the gross dividend, tax that gross figure at your marginal rate, and then subtract the credit, so the same profit is taxed only once and you simply top up to your personal rate. A shareholder on 33 or 39 percent pays the difference above 28 percent, often collected as resident withholding tax, while someone on a lower rate may end up with excess credits. You enter the cash dividend you received, the imputation rate (usually 28 percent), and your marginal tax rate, and the calculator shows the imputation credit, the grossed-up dividend, the tax on it and the extra tax payable or the credit left over. Use it to understand your dividend tax and to check the figures on your statements. This is general information about the imputation system, not tax advice; an accountant can confirm your position.
