The Ireland Dividend Tax calculator shows what you actually keep from a dividend after Irish tax. Two layers apply: a flat Dividend Withholding Tax (DWT) taken at source, and your personal income tax plus social charges on the dividend as income. Because the withholding is only a payment on account, the final result depends on your own tax bands.
How it works
When an Irish company pays a dividend it deducts 25% DWT at source, so you receive 75% in cash up front. At year end the gross dividend is taxed as income at your marginal rate — 20% in the standard band or 40% in the higher band — and then PRSI (usually 4%) and USC are added on top.
The total charge is gross x (income rate% + PRSI% + USC%). The 25% DWT already withheld is
credited against that total, so your remaining balance is total tax − DWT credit, and your net
dividend is gross − total tax.
Net dividend = gross − (income tax + PRSI + USC). DWT of 25% is credited, not extra tax.
If your combined rate is below 25% you may be due a refund of the over-withheld DWT; if it is above 25% you owe the difference when you file.
Tips and notes
The 25% withholding is never the end of the story — a higher-rate taxpayer typically owes well above 25% once PRSI and USC are added, while someone in the standard band may reclaim part of the DWT. Always declare dividends on your return. Non-residents and foreign dividends follow different rules (treaty relief, exemptions, foreign withholding), so set the rates to match your situation and confirm anything unusual with Revenue or an accountant.
