Productivity Bonus Tax Calculator
Up to 6% of annual base pay can be free of Portuguese income tax. See what applies to you.
Base pay is the contractual base salary, without the meal allowance or other supplements. The salary rise is the company's, not yours, and it is the condition that decides everything: it must be at least 4.6% in 2026.
The bonus does not arrive tax-free on the payslip. In the month it is paid, €168.15 is withheld, because the employer does not yet know whether it will close the year with the required salary rise. The €141.25 on the exempt part comes back in the following year's tax settlement.
The bonus exceeds the exempt ceiling of €1,260.00. The excess of €240.00 is taxed normally as employment income.
The calculator does not verify whether your employer met the salary-rise condition, which is only established once the financial year closes and is reported to you in the annual income statement, nor does it compute your full annual income tax. Out of scope: the Azores and Madeira withholding tables, the disability and pension tables, and the relief the company gets on its own tax.

The 6% is measured on 14 months of base salary, and nothing else
Article 96 of Law 73-A/2025 exempts these amounts from income tax «up to a limit of 6% of the worker’s annual base remuneration», and almost everyone stumbles on that phrase. It is not 6% of what you earned in the year, nor 6% of gross pay with all its supplements, nor even 6% of twelve months of salary. The Portuguese tax authority answered it in binding terms: annualised base remuneration counts the base pay earned over 12 months plus the 13th and 14th months, meaning the Christmas and holiday subsidies that are paid compulsorily, and excludes any other salary supplement, whether fixed or variable. It is 14 months of base pay, and only that. On a base salary of 1500 EUR that gives 21 000 EUR of annual base pay and therefore 1260 EUR of exempt bonus a year. Anyone working from twelve months arrives at 1080 EUR and gives up 180 EUR of exemption. It is worth recording that the binding information contradicts itself in the same paragraph, opening by admitting fixed supplements and closing by excluding them; the concluding sentence, the one that says what «only» counts, is the one this calculator follows.
Both conditions sit with the employer
This is the most unusual relief in the Portuguese income tax code, because the worker controls neither of the conditions it depends on. The first is the form of the award: it must be paid «voluntarily and without regular character». The second, in article 96(2), is more demanding still: the exemption depends on the employer having made, in that same year, a salary increase that qualifies under article 19-B of the Tax Benefits Statute. That article, in the wording given by the same budget law, requires a rise of at least 4.6% on two fronts: in the company’s average annual base pay, and in the base pay of workers earning at or below that average. Note the figure, because it is the difference between this page and most of what remains published: the threshold was 4.7% in 2025 and fell to 4.6% for 2026. A rise of 4.65% fell short last year and clears the bar this year.
What counts as voluntary, and why a target-based bonus does not
The phrase «voluntarily and without regular character» looks like a formality and is, in practice, the filter that excludes most real bonuses. The tax authority was asked exactly this and answered in binding terms: a bonus previously defined in an internal regulation, even one conditioned on meeting objectives or metrics, cannot be treated as awarded voluntarily. The reasoning is that if the bonus is pre-established by objective and general criteria, the worker can count on receiving it once the targets are met, the right becomes vested and the payment stops being discretionary. The same applies from the regularity side: awarding bonuses annually, on a recurring basis, defeats the exemption even when no such right is written down anywhere. What survives is the genuinely extraordinary bonus, decided by management that year and promised to nobody. That is why the calculator asks how the bonus was awarded, and not only how much it was.
The money does not arrive tax-free: it arrives in next year’s refund
This is the part that surprises everybody and the reason the calculator shows two net figures rather than one. The tax authority set out the mechanism in Circular 20282/2025: at the moment the bonus is paid, the employer does not yet know whether it will actually meet the pay-rise requirements, because that is only established once the financial year closes. The bonus is therefore withheld in full as taxable employment income, at the rate applying to that month’s remuneration, and reported under code A. Only after the tax period ends, once the condition is verified, does the employer file a replacement monthly remuneration return that separates out the exempt part under code A41, by subtraction from the income already declared, leaving the withholding where it was. The circular adds that no penalty applies to that replacement filing. The practical result is that the worker sees the bonus arrive with tax already deducted and recovers the exempt part in the following year’s settlement, not on the payslip.
Worked example
Take a base salary of 1500 EUR a month and a productivity bonus of 1500 EUR awarded in 2026, at a company that raised salaries by 5% that year and decided the bonus at its discretion. Annual base pay is 14 × 1500 EUR, so 21 000 EUR, which puts the exempt ceiling at 1260 EUR. Of the 1500 EUR bonus, 1260 EUR is exempt and the remaining 240 EUR is taxed. The withholding rate on that month’s remuneration is 11.21%, so 168.15 EUR is withheld on the whole bonus in the month it is paid and 1331.85 EUR reaches the account. At the following year’s settlement the tax that stays paid is only the tax on the 240 EUR taxed portion, that is 26.90 EUR, and 141.25 EUR comes back. Adding the 138.60 EUR of social security that does not fall on the exempt part, the saving reaches 279.85 EUR. The same amount paid as ordinary salary would leave 1166.85 EUR in hand, against the 1473.10 EUR this bonus ends up leaving.
