Belgium Tax Guide 2026 — Expat Regime, High Taxes & Why Brussels Still Attracts Talent

Belgium has Europe's highest tax wedge — but the expat regime (revamped 2022) and Brussels premium keep international talent coming.

Expat Regime 2026 (Post-2022 Reform)

Feature	Details
Exemption	30% of gross salary tax-free (capped)
Cap	€90,000/year (2026 indexed)
Effective benefit	Max €27,000/year exempt
Duration	5 years (year of arrival + 4)
Eligibility	Not tax resident in BE for prior 5 years; recruited from abroad; specialist role

2022 change: Replaced old "expat status" (complex, case-by-case) with simple 30% exemption + cap. Much clearer.
