i.e. a 100,000 EUR annual salary, the employer pays ~40,000 EUR to the government, then the employee gets their wage slips with additional deductions of ~38,000 EUR.
= total of ~78,000 EUR tax on a 100,000 EUR salary.
I don't think anything like that level of taxation exists in the US?
At 100,000 USD (a bit lower than EUR) the combined tax load on income for both employee and employer is typically ~30-35% depending on locale. In the US, $100k is pretty close to the median household income.
If you have extremely high incomes (e.g. 1,000,000+ USD) the gap closes a bit but even in the highest tax locales the marginal tax loading maxes out at ~60% of top-line income.
US Federal tax rates are some of the most progressive in the world. Only ~20% of households are net taxpayers after transfer payments and subsidies. Ironically, this is why it is so difficult to significantly increase income tax revenue in the US. It would require the middle-class majority to vote to raise their own taxes.
