The OECD measures something called the tax wedge — the total gap between what an employer pays for a worker and what the worker takes home, expressed as a percentage of total labor cost. It includes income tax, employee social contributions, and employer social contributions. For a single worker at average national wages, here are the 10 highest-burden countries in the world (OECD Taxing Wages 2024):
The ranking
| Rank | Country | Tax wedge | Net take-home (of gross) |
|---|---|---|---|
| 1 | 🇧🇪 Belgium | 53.0% | 47% |
| 2 | 🇩🇪 Germany | 47.9% | 52% |
| 3 | 🇦🇹 Austria | 47.2% | 53% |
| 4 | 🇫🇷 France | 47.0% | 53% |
| 5 | 🇮🇹 Italy | 45.1% | 55% |
| 6 | 🇸🇪 Sweden | 43.6% | 56% |
| 7 | 🇭🇺 Hungary | 43.2% | 57% |
| 8 | 🇨🇿 Czech Republic | 43.0% | 57% |
| 9 | 🇫🇮 Finland | 42.7% | 57% |
| 10 | 🇸🇰 Slovakia | 42.1% | 58% |
For comparison: the OECD average is 34.8%. Switzerland sits at 23%, the US at 28%, and Australia at 28%. The gap between Belgium and Switzerland is 30 percentage points — on the same gross salary, a Belgian worker takes home roughly €23,000 less on a €80,000 package than a Swiss equivalent.
High tax ≠ bad outcome
The simplistic conclusion — high taxes mean you keep less — misses the redistribution side. Sweden at 43.6% also provides:
Universal healthcare with no co-payments for inpatient care. Free university education for all citizens, plus a student stipend of ~800 EUR/month. 480 days of paid parental leave per child, shared between parents. Unemployment insurance covering up to 80% of prior salary for 300 days.
The question isn't whether you pay 43% or 23% in taxes — it's whether the services you receive in return are worth the difference. That calculation is deeply personal and depends on how much you use public systems.
Why Belgium tops the list
Belgium's 53% tax wedge is partly structural. The country has one of the highest employer social contribution rates in the OECD — around 25% of gross wages — layered on top of progressive income tax and employee contributions. This creates a situation where a Belgian worker earning €60,000 gross costs their employer closer to €75,000 in total, while the worker takes home around €35,000 net. The rest — €40,000 — goes to the state.
Belgium has repeatedly tried to lower this burden through "tax shifts" (moving taxation from labor to consumption) without reducing public spending. The political difficulty of those reforms explains why Belgium has led the ranking for over a decade.
Where France lands — and why
France at 47% sits in 4th place, driven by unusually high social contributions rather than income tax rates. French income tax brackets are not the highest in the OECD. But France's social security system — which includes retirement pensions, healthcare, unemployment, and family benefits — is funded largely through payroll contributions, both from employees and employers.
A French worker paying 47% of labor cost in taxes funds: retirement pension (régime général + complémentaire), full healthcare reimbursement above the base rate (sécurité sociale + mutuelles), generous maternity leave (16 weeks at 100% salary), and family allowances for parents with two or more children.
Net take-home comparison: same gross, different countries
| Country | Gross annual salary | Net take-home | Effective rate (employee only) |
|---|---|---|---|
| 🇨🇭 Switzerland | €80,000 | €61,600 | 23% |
| 🇺🇸 United States | €80,000 | €56,800 | 29% |
| 🇬🇧 United Kingdom | €80,000 | €52,800 | 34% |
| 🇫🇷 France | €80,000 | €43,200 | 46% |
| 🇧🇪 Belgium | €80,000 | €37,600 | 53% |
The difference between Switzerland and Belgium at the same gross is €24,000 per year in net income. Over a 30-year career, compounded at even modest investment returns, the cumulative wealth gap from that difference alone is substantial. This is why tax optimization through country of residence has become a real strategy for high-income earners — particularly those whose work is location-independent.
