Cost of Living

Belgium offers genuine value within Western Europe. Brussels is the most expensive city but remains 30–40% cheaper than Paris or Amsterdam for rent. Antwerp and Ghent are significantly more affordable. Groceries, dining, and utilities are broadly similar across cities — the difference lies primarily in rent. The BISR expat tax regime can meaningfully improve net disposable income for qualifying workers.

Opening a Belgian bank account requires your national number from the commune registration. Major banks — BNP Paribas Fortis, KBC, ING Belgium, and Belfius — offer multilingual online banking and welcome expat customers. Belgian banking heavily uses Bancontact for in-person payments and online transactions.

Belgian income tax is progressive, with marginal rates of 25% (up to €15,820), 40% (€15,820–€27,920), 45% (€27,920–€46,440), and 50% (above €46,440). These are among Europe's highest headline rates. However, the BISR expat tax regime dramatically reduces the effective rate for qualifying international workers by allowing 35% of gross salary to be received tax-free.

Self-employed workers in Belgium (indépendant/zelfstandige) face the same progressive tax rates as employees but must also pay quarterly social security contributions. The administrative burden is higher — quarterly VAT returns, social insurance fund membership, and annual tax filing through a comptable (accountant) are practically mandatory. The upside is access to Belgium's strong market and EU institutional contracts.

Belgium's pension system has three pillars: the state pension (funded by social security), occupational pensions (offered by many employers), and individual pension savings (tax-advantaged). The state pension is relatively modest — the maximum is approximately €1,600/month for employees with a full career. Most expats supplement with occupational and private pension savings.
