The dividend has two routes and you pick one
The default needs no decision from you. Your company withholds 28% when it pays the dividend and the tax ends there: the taxa liberatória is a final withholding, not an advance. The dividend never enters your taxable income, so your salary cannot push it into a worse bracket and the solidarity surcharge cannot reach it.
The second route is englobamento. You elect it in your annual return, the dividend joins your general IRS base, and it is taxed on the same scale as everything else you earn, from 12.5% at the bottom to 48% at the top. The company still withholds the same amount at payout, but here that money is only a payment on account. If the scale produces less tax than was withheld, the difference comes back to you.
A Spanish shareholder has nothing of the sort to weigh: there, the savings scale is the only route a dividend has. The election is the reason this page has a dropdown and the Spanish one does not.
Aggregation wins more often than founders expect
Only 50% of a distributed profit enters the base under englobamento. Half a dividend taxed at the very top rate of the scale still costs less than the flat rate applied to all of it, and the gap widens as the rest of your income falls. A founder on a modest salary who elects aggregation can get a chunk of the withholding refunded.
The half-inclusion carries a condition this calculator cannot check: the paying company must be subject to Portuguese corporate tax and not exempt from it, or be an EU parent-subsidiary entity. Your own Lda qualifies. A dividend from somewhere else may enter your base in full, and the model would not know the difference.
There is also a cost on the other side of the ledger. The half that does enter counts toward the rendimento coletável on which the additional solidarity rate bites, so aggregation can add 2.5% above €80,000 that the flat route would never have triggered.
The election is annual and it takes the whole category with it
You do not choose per dividend. Elect englobamento and you are obliged to aggregate every item of investment income you hold that year, and the others (bank interest, coupons, dividends from elsewhere) come in at their full value, not at half. Only company profits get the half-inclusion. Run the numbers on the whole category before you tick the box, not just on the dividend that made you think about it.
The profit is still taxed twice
Before it reached you it was company profit, and it paid corporate tax. Portugal returns none of that to the shareholder. The half-inclusion looks like an imputation credit and is not one: it shrinks your base rather than refunding the company’s tax, and it is worth only half your marginal rate.
If you are weighing this against paying yourself a salary, which is deductible for the company and lands on the general IRS scale, the two levels are worked through together on the Portuguese founder page.
Last year’s answer is not this year’s
The scale that englobamento runs on is the one enacted in the budget law for 2026, and it is redrawn every year. The flat route stands still. So the comparison shifts under you even when nothing about your company changes, and the election is made afresh in every return anyway, which makes rechecking it cheap.
