International freelancers face complex multi-country tax situations. This guide explains tax residency, self-employment tax, VAT, and how to stay compliant across borders.
You live in Germany, your clients are in the US, and you get paid into a Wise account in GBP. Which country's taxes do you pay? What currency do you report income in? Do you pay VAT?
These questions are genuinely complex. This guide breaks down the core principles — but always consult a local tax professional for your specific situation.
The most important concept: tax residency, not citizenship or where your clients are, determines where you pay tax on worldwide income.
Tax residency is typically determined by:
- Physical presence (183-day rule in most countries)
- Permanent home location
- Center of vital interests (family, social ties)
- Habitual abode
If you spend 183+ days in Germany, Germany taxes your worldwide income — including your US client payments.
In most countries, self-employed people pay both employee AND employer portions of social contributions. In the US, this is the self-employment tax (15.3%). In Germany, it's Rentenversicherung and Krankenversicherung.
Budget 25-35% of gross income for all taxes and social contributions, regardless of where you live.
If you're EU-based and bill US clients, you typically don't charge VAT to non-EU businesses (B2B reverse charge rules). But if you bill EU consumers, VAT applies.
If you earn above the VAT threshold in your country (€22,000 in Germany for Kleinunternehmer), you must register and charge VAT.
If you accidentally pay tax in two countries (rare with proper residency planning), most countries offer a foreign tax credit to prevent double taxation. You offset taxes paid abroad against your domestic tax liability.
