The verdict
The United States usually wins the rate table. Federal ordinary income tax tops at 37%, long-term capital gains are often 0% to 20%, and C corporations pay 21% federally. Germany's personal scale reaches 45%, investment income is commonly 25% plus the 5.5% solidarity surcharge, and companies typically sit near 30% once trade tax is included.
The comparison is not a clean federal-versus-federal story. A U.S. citizen or green-card holder remains on the U.S. worldwide system after a move to Berlin or Munich. Germany then adds wage-tax withholding, payroll social security of about 20% for employees, church tax in participating states, and the solidarity surcharge on many income-tax and corporation-tax liabilities.
Choose the United States when U.S. customers, fundraising or a low-tax state is the real plan. Choose Germany when the EU market, German employment or family life is the point. Do not treat a German assignment as a U.S. tax exit.
How to read this comparison
Germany is a high-compliance social-state tax system. The United States is a layered federal-and-state system that follows its citizens. That is the comparison that matters, not a one-line rate contest.
U.S. ordinary federal rates run from 10% to 37%. Long-term capital gains and qualified dividends can use 0%, 15% or 20%, and high earners can also owe 3.8% NIIT. There is no federal VAT and no federal net wealth tax. The federal estate tax can still reach 40%. Those federal numbers look competitive against Germany until you add a high-tax state, payroll taxes and the fact that a U.S. passport does not stop at the German border.
Germany taxes residents on worldwide income. The 2026 personal tariff is progressive from 0% to 45%, with a EUR 12,348 basic allowance. The 5.5% solidarity surcharge still attaches to many income-tax and corporation-tax bills, and church tax can apply in participating states. Employees also fund social security through payroll, commonly around 20% on the employee side before employer contributions. Private investment income is often collected as Abgeltungsteuer at 25% plus the surcharge, producing 26.375% in the ordinary case.
Companies are the other German weight. Corporation tax of 15% plus solidarity surcharge is only the federal slice. Local trade tax usually lifts the combined burden to about 30%. That is heavier than a 21% U.S. C corporation before state tax, and it is a poor match for a founder who expected โEU company, U.S. rates.โ
VAT is 19% standard and 7% reduced. Inheritance and gift tax run from 7% to 50% by class of heir. There is no German net wealth tax, which is one of the few areas where Germany is not automatically harsher than a U.S. person with a large estate.
A move only works if you model both systems at once: U.S. citizenship or green-card status, German wage tax, social-security totalization, treaty residence and the state you are leaving. A German employment contract is not an expatriation plan.
