Belgium (country) and Portugal (country) have distinct approaches to taxing employment income. On a gross salary of €80,000, the effective total deduction rate is 43.2% in Belgium compared to 40.1% in Portugal. That translates to a difference of roughly €2,419 per year in favor of Portugal.

The net annual take-home is €45,468 in Belgium and €47,887 in Portugal. These figures assume a single filer with no children or special deductions. Actual results vary based on household composition, deductions, and specific tax credits available in each jurisdiction.
Equivalent gross and tipping point
At €80,000 gross in Belgium, about €75,100 gross is needed in Portugal to reach the same net salary.
That figure answers the same net. For the gross that gives back the same purchasing power, restated at each side's price level, the two answers sit side by side.
Over the €30,000 to €250,000 gross range the ranking reverses at around €45,500: below that level Belgium leaves the higher net salary, above it Portugal does.
These figures use the default profile. The Expat Package Report runs the same calculation on your own two salaries and household, and quantifies the gap in euros.

Special tax regimes
The figures on this page apply the ordinary scale. Where one of the two sides opens a tax regime of its own for arrivals from abroad, it is computed alongside here, without changing the comparison above.
Belgium · BBIB Expat Regime
Up to 35% of gross remuneration is exempt from income tax as costs proper to the employer, without ceiling, for remuneration paid from 1 January 2025 (law of 18 December 2025, Belgian Official Gazette of 30 December 2025, articles 15 to 18, which also lowered the salary threshold to 70,000 EUR). For social security the exemption stays at 30% of remuneration, capped at 90,000 EUR a year: the royal decree of 28 November 1969 (article 19, paragraph 2, 4°) refers to the version of the regime in force on 1 January 2022 and was not amended, as the ONSS administrative instructions 2026/3 state, so the tax and social treatments differ. Applies to employees and executives recruited from abroad or seconded to Belgium. The comparison above applies the ordinary scale and does not assume this regime.
| Gross (EUR) | Net Belgium, ordinary scale | Net under the regime | Difference (signed) |
|---|---|---|---|
| €45,000 | €30,355 | €38,295 | +€7,940 |
| €80,000 | €45,468 | €61,240 | +€15,772 |
| €120,000 | €61,636 | €86,294 | +€24,658 |
| €250,000 | €114,186 | €165,556 | +€51,371 |
Who this regime is open to
Cumulative conditions: recruited directly from abroad or seconded within a multinational group; during the 60 months before taking up the position in Belgium, neither a Belgian tax resident, nor subject to the non-resident tax on Belgian professional income, nor living within 150 km of the border; gross annual remuneration above 70,000 EUR; regime granted on application approved by the tax administration. Whether a given move qualifies is a question for a tax lawyer, not for this calculator.
Portugal · IFICI (NHR 2.0)
Tax incentive for scientific research and innovation (IFICI), successor to the NHR: 20% flat rate on qualifying Portuguese-source employment and self-employment income for 10 years. Most foreign-source income is exempt, except pensions. The former NHR closed to new entrants on 1 January 2024 (transitional registrations until 31 March 2025); existing beneficiaries keep it until the end of their 10 years. The comparison above applies the ordinary scale and does not assume this regime.
| Gross (EUR) | Net Portugal, ordinary scale | Net under the regime | Difference (signed) |
|---|---|---|---|
| €45,000 | €30,282 | €31,050 | +€768 |
| €80,000 | €47,887 | €55,200 | +€7,313 |
| €120,000 | €66,923 | €82,800 | +€15,877 |
| €250,000 | €127,087 | €172,500 | +€45,413 |
Who this regime is open to
Became a Portuguese tax resident from 2024 onwards and not a Portuguese tax resident in the previous 5 years. Limited to qualifying activities (research, innovation, certain highly qualified professions). Foreign pensions are not covered by the regime. Whether a given move qualifies is a question for a tax lawyer, not for this calculator.
Cost of living
Consolidated cost-of-living index (Paris = 100): Brussels 90, Lisbon 70. This is a rounded editorial benchmark, built from Numbeo readings and official statistics rather than published by them. On a gross salary of €80,000, the net amounts adjusted to this index correspond to a purchasing power on the order of €51,000 for Brussels and €68,000 for Lisbon, at Paris price levels.
