How is net salary calculated for Belgium?

For Belgium, we apply the official tax brackets in force and social contributions to the gross salary. The gross is entered in EUR and converted to EUR at the ECB reference rate before calculation.

What assumptions does this comparison use?

Both calculations assume a single filer with no children, no special deductions or tax regimes, and standard filing options. For Swiss cantons, the main municipality is used with age group 35-44, no church tax, and no Pillar 3a contribution. For US states, the standard deduction is applied.

Are the amounts in the same currency?

Each side shows amounts in the local currency of that jurisdiction (EUR for Belgium, CHF for Geneva). The input gross salary is in EUR, converted to each local currency at ECB reference rates. The effective rate comparison is currency-independent.

Can I change the salary or filing status?

The tool above lets you enter any gross salary in EUR and choose from five household configurations: single, married, or married with 1-3 children. The comparison updates in real time.

How often are tax rates updated?

Tax brackets and social contribution rates reflect the tax year stated in the source line below the tables. Exchange rates are updated regularly from ECB reference rates. We update rates whenever official sources publish new figures.

Comparing taxes: Belgium and Geneva

Belgium (country) and Geneva (Swiss canton) 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 22.0% in Geneva. That translates to a difference of roughly €16,902 per year in favor of Geneva.

In Belgium, income tax amounts to €24,077 and social contributions add €10,456. In Geneva, federal tax is 779 CHF with cantonal/municipal taxes of 7,364 CHF and social contributions of 8,306 CHF.

The net annual take-home is €45,468 in Belgium and 58,191 CHF in Geneva (amounts in respective local currencies, converted from the same EUR gross). 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 €54,200 gross is needed in Geneva 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.

Across the €30,000 to €250,000 gross range, Geneva leaves the higher net salary at every level tested.

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.

Cost of living

Consolidated cost-of-living index (Paris = 100): Brussels 90, Geneva 135. 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 €46,000 for Geneva, at Paris price levels.
