Understanding Dividends and Imputation

🧾 Imputation Credits

Why They Exist

A company pays company tax on its profit before paying a dividend. Without imputation, that profit would be taxed again as your income, taxing it twice. Imputation credits represent the company tax already paid, and you can use them to offset your own tax on the dividend.

Fully vs Partly Imputed

A fully imputed dividend carries credits for the full company tax paid. A partly imputed or unimputed dividend carries fewer or no credits, which means more tax is left for you to pay. The imputation level affects your after-tax return.

📊 How Dividend Tax Works

Gross Dividend and Your Rate

Your gross dividend is the cash you receive plus the imputation credits attached. You are taxed on that gross amount, usually at 33% for dividends. The imputation credits cover most of the tax, and the payer withholds a small amount of resident withholding tax (RWT) to bring the total up to your rate.

Our Dividend Calculator works out the cash, imputation credits, gross, RWT, and the net dividend for your situation.

Why High and Low Earners Differ

If your tax rate is exactly covered by the credits, little or no extra is taken. A higher earner may have a bit more to pay, while someone on a lower rate might even be due a refund of excess credits through their return.

Dividend Reinvestment Plans

Some companies offer to reinvest your dividend into more shares automatically. This compounds your holding over time, though the dividend is still taxable even when reinvested rather than paid in cash.

💡 Common Mistakes

Mistake 1: Ignoring Imputation Credits

The cash dividend is not the whole story. The attached credits are part of your gross dividend and your tax, so ignoring them misreads your real return and tax position.

Mistake 2: Assuming All Dividends Are Fully Imputed

Partly imputed or overseas dividends carry fewer credits, leaving more tax for you. Check the imputation level.

Mistake 3: Thinking Reinvested Dividends Are Tax-Free

A reinvested dividend is still income and still taxable, even though you did not receive cash.

Mistake 4: Chasing Yield Alone

A high dividend yield can come from a falling share price or an unsustainable payout. Look at the whole picture, not just the yield.

A Simple Approach

See our RWT and PIR and Investing Basics guides. Final word: a dividend is your share of company profit, and in New Zealand it usually comes with imputation credits that pass on the company tax already paid, preventing double taxation. You are taxed on the gross dividend at your rate, mostly covered by credits. This is general information, not financial or tax advice.
