This Portugal dividend tax calculator shows what you keep from a dividend under Portugal’s two IRS methods: the flat 28% withholding (retencao na fonte), which is usually a final tax, or englobamento, where only 50% of the dividend is added to your income and taxed at the progressive marginal rates. Enter your figures to see the tax and net income under each, and which wins.
How it works
Flat method: tax is simply gross dividend × 28%, withheld at source. Nothing further is due.
Englobamento method: only 50% of the gross dividend is added to your other taxable income. The extra tax is the difference between your IRS bill with and without that half-dividend, computed across the progressive brackets. Because only half is included, the effective rate can fall below 28% when your income is modest.
The tool compares both and highlights the cheaper option, so you can decide whether to tick the englobamento box on your IRS return.
Example
On a €1,000 dividend, the flat method takes 1,000 × 28% = €280, leaving €720. Under englobamento with €15,000 of other income, only €500 is added; taxed at a marginal rate around 23%, the extra tax is roughly €115 — so englobamento leaves about €885, clearly better at that income level. At high incomes the flat 28% usually wins.
Notes
This models resident Portuguese/EU dividends. It excludes the foreign-withholding tax credit for overseas dividends, the additional solidarity surcharge at very high incomes, and any deductions that interact with englobamento. The IRS marginal brackets used are the mainland 2024 scale. Confirm with an accountant before electing englobamento, as it applies to all your category-E income for the year.
