About TK — Why It Matters for Expats
Techniker Krankenkasse (TK) is Germany's largest statutory health insurer (gesetzliche Krankenversicherung / GKV), covering 12.3 million people. Founded in 1884 originally for technical workers, TK has evolved into one of Germany's most modern, digitally advanced insurers.
For expats, TK stands out for three key reasons: partial English support (the only major German public insurer to offer English-language phone service), a below-average contribution rate (17.29% vs. a market average exceeding 20% for many competitors), and an excellent digital app with English functionality for routine tasks.
On 19 December 2025, TK's supervisory board set the 2026 Zusatzbeitrag at 2.69%, up from 2.45% in 2025 but still well below the government-mandated average benchmark of 2.9%. The total rate of 17.29% makes TK one of the most affordable major public insurers in Germany for 2026.

What TK Covers — Key Benefits for Expats
All German statutory insurers cover the same legally required services. Here's what that means in practice for expats:
GKV vs. PKV: Should You Consider Private Insurance?
Germany's health insurance system has a fundamental split: GKV (gesetzliche Krankenversicherung) — statutory public insurance like TK — and PKV (private Krankenversicherung) — private insurance.
For most expats, especially those earning below the Versicherungspflichtgrenze of €73,800/year gross (2026), GKV is mandatory. If you earn above this threshold, you can opt out of GKV and take PKV instead. Key considerations for expats:
- GKV (TK): Family members covered for free (non-earning spouse/children), rate-based contribution (scales with income), no age penalty, standardized coverage.
- PKV: Often better coverage and faster specialist appointments, but monthly premiums are based on age and health status — not income. Premiums rise with age. Family members are NOT covered for free.
- Expat recommendation: Unless you're a high earner planning to stay in Germany long-term, GKV with TK is the safer, more predictable choice.
How to Enroll with TK as an Expat

- Submit documents: Work contract (Arbeitsvertrag), passport/ID, and in some cases visa/residence permit copy.
- Receive Mitgliedsbescheinigung — TK membership certificate. Give this to your employer immediately — they need it to register you with the system.
- Employer handles contributions — Your employer deducts your employee share (8.645%) from your salary and pays both their portion and yours directly to TK.
- Get your health card (Gesundheitskarte) — arrives by post within 2–3 weeks. Show it at every doctor visit. Lose it? Report via TK app for replacement.
Frequently Asked Questions
-
Yes — after a minimum membership period of 12 months with your current insurer. Since TK raised its Zusatzbeitrag in January 2026, existing TK members received a Sonderkündigungsrecht (special termination right) — they can switch without the 12-month lock-in. To switch to TK: apply on tk.de, TK handles the notice to your old insurer automatically.
-
Within the EU/EEA, your TK EHIC card covers emergency and medically necessary treatment. Outside the EU (USA, Asia, South America), TK has very limited coverage. For non-EU travel, always add a separate Auslandsreisekrankenversicherung (travel health insurance) — typically €50–100/year for annual coverage.
-
Yes, but the calculation is different. Freelancers pay both the employee and employer share — meaning the full 17.29% on your income. The minimum monthly contribution is based on an assumed income floor set by TK. Many freelancers opt for PKV due to the potentially lower premiums when healthy and younger.
