Germany’s health system can feel like a maze the first time you see words like gesetzliche Krankenkasse, Beitragsbemessungsgrenze, or Mitgliedsbescheinigung. The good news: if you’re new to Germany on a work visa, as a student, or as a family member, joining Techniker Krankenkasse (TK) is a clear and reliable way to get comprehensive, legally compliant coverage from day one. TK is Germany’s largest statutory health insurer and a popular choice among immigrants thanks to English support, fast documentation for employers and universities, and a modern app that makes paperwork far less painful.
This guide explains how TK health insurance works for foreigners in 2025: who is eligible, how contributions are calculated, the role of your employer, what documents you need, and how to get insured quickly for visa, work, or study. You’ll also find up-to-date salary thresholds, contribution caps, and family-insurance rules in one place, plus a simple table you can save for your move.
How TK insurance works
TK belongs to Germany’s statutory health insurance system (GKV). If you are employed below the annual compulsory insurance threshold, you must join public insurance and can pick a fund such as TK. If your salary sits above the threshold, you may choose between staying in public insurance (voluntarily) or taking a private plan. TK provides the same core benefits package mandated by law, with its own additional service extras and a fund-specific supplemental contribution.
For 2025, TK’s total health contribution rate is 17.05% of gross salary: a general rate of 14.6% plus TK’s fund-specific supplemental rate of 2.45%. Employers pay half and employees pay half, and contributions are only charged up to the legal contribution ceiling; income above the ceiling is not assessed.
2025 income rules at a glance
Two national figures matter for anyone comparing TK with other options. The compulsory insurance threshold (often called the annual income limit or JAEG) is 73,800 euros for 2025. Employees below this are mandatorily insured in public health insurance; those above it can choose public or private. Separately, the contribution ceiling for health insurance is 66,150 euros per year in 2025; contributions are calculated only up to that amount.
Why this matters: if you earn well over the ceiling, your monthly TK premium won’t keep rising with every pay increase; it’s capped by law. If your gross income rises above the compulsory threshold, you don’t lose public insurance—many high earners simply stay with TK voluntarily because of predictable costs and broad coverage.
Who is eligible to join
Employees below the 73,800-euro threshold are required to join public insurance and can select TK. High earners above the threshold may remain with TK as voluntary members. International students under standard student-eligibility rules can join TK at nationally regulated student rates. Non-working spouses and children may be covered free of charge through family insurance if their incomes stay below the annual family-insurance limits and other conditions are met.
For family insurance in 2025, the general monthly income limit is 535 euros; for mini-jobs, the special limit is 556 euros. If a spouse or child regularly earns more than these amounts, they typically need their own insurance.
What TK coverage includes
TK’s statutory package covers GP and specialist visits, hospital treatment, prescribed medicines, maternity care, and a wide range of preventive services. Your TK eHealth card doubles as your European Health Insurance Card (EHIC) on the back, giving access to medically necessary treatment during temporary stays across the EU and certain partner countries. For digital convenience, the TK-App lets you manage documents, request certificates, and access TK-Safe, TK’s interface to the electronic patient record (ePA).
The electronic patient record is being rolled out across Germany in 2025 with an opt-out model, meaning publicly insured patients receive an ePA unless they decline. TK provides access to the ePA via TK-Safe and the TK-Ident app, which also enables secure log-ins to approved digital health applications.
Employer sponsorship and cost split
In Germany, employers effectively “sponsor” public health insurance by paying half of the contributions for employees. Once you choose TK, your employer registers you and sends the employer share directly each month; your share is withheld from payroll. Because TK’s total 2025 rate is 17.05% and employers cover half, the employee’s health contribution is about 8.525% of assessed income, up to the contribution ceiling.
Practically, this split means public health insurance is predictable—especially for new arrivals who need visa-compliant coverage without underwriting or long waiting periods. TK membership also generates the insurance certificate employers and immigration offices often ask to see before onboarding or issuing a residence permit.
How to apply step by step
- Choose TK and start the online application. Filling out the form takes only a few minutes; you’ll receive a membership confirmation your employer or university can use. If you need a certificate urgently, you can download one via the TK-App or your TK online account.
- Provide passport and local details. TK will need your personal data, German address (or planned address), and, if employed, your start date and employer’s details. Students provide their study information for the student tariff and university enrollment.
- Coordinate with your employer or university. Employers register you electronically and begin payroll contributions; universities receive your insurance status confirmation directly from TK for enrollment. If you already hold public insurance elsewhere in the EU, TK can coordinate status without gaps.
- Receive your TK eHealth card. Your physical card arrives by post after your membership is confirmed; meanwhile, your digital membership certificate is accepted by HR and most authorities. The EHIC is printed on the back of the card.
Costs and contribution examples
TK’s total rate in 2025 is 17.05% of gross salary (14.6% general rate plus 2.45% TK supplemental rate), split equally between you and your employer. Contributions are assessed only up to the health-insurance ceiling of 66,150 euros per year (5,512.50 euros per month). Above that monthly amount, your payment does not increase.
If you are a full-time employee, your personal health contribution is about 8.525% of your assessed income each month; the employer pays the same again. Students typically pay a national student contribution amount rather than a percentage; universities in 2025 quote approximately 145 euros per month (health plus long-term care) as a planning figure. Always check TK’s current student contribution page for your exact age and family situation.
Students, graduates, and researchers
International students can join TK if they meet standard student requirements in Germany. Your university will not enroll you without proof of compliant health insurance; TK can send confirmation directly. If you are over the student age or semester limit, TK will advise on the correct tariff. For exchange students with an EHIC or S1, TK can confirm exemption for enrollment. Newly graduated Blue Card holders and researchers can switch to an employee policy the day their contract begins—your HR team simply needs your TK membership certificate.
If your student status ends or you take a paid internship, tell TK as soon as your circumstances change so your coverage type updates correctly. This prevents back payments and ensures your contributions match your new status.
Family insurance and dependents
One reason many families choose TK is the ability to co-insure spouses and children at no extra cost when certain conditions are met. In 2025, the general income limit for a family member to stay co-insured is 535 euros per month; for mini-jobs, it is 556 euros. If a spouse or adult child’s income regularly exceeds those amounts, they will need their own insurance, either with TK or another compliant provider.
Note that family insurance does not apply to a spouse who is primarily self-employed, and special rules apply if the higher-earning spouse is privately insured. TK provides detailed English guidance and can advise which documents they need to confirm eligibility.
Care on the road and digital tools
Your TK card includes the EHIC for medically necessary treatment during temporary stays across the EU and certain partner countries. For trips beyond EHIC coverage, TK partners offer low-cost add-on travel policies; many members buy these for vacations or long visits outside the EU. In daily life, the TK-App lets you send documents, request certificates, and manage your account; TK-Safe gives you secure access to your electronic patient record as the national rollout continues in 2025.
When you need advice, TK’s medical hotline provides round-the-clock access to German specialists. For general customer service, English lines are available during business hours; the hotline can also point you toward local providers who speak your preferred language.

Visa, onboarding, and timelines
If you need health insurance for your visa or university enrollment, TK can quickly issue a membership certificate you can download in the TK-App or your online account. Employers commonly request this certificate before your first payroll; universities receive your status electronically. Your physical TK eHealth card typically arrives by post after your membership starts. For students arriving before term, ask TK when your coverage starts and whether you need a short travel policy to bridge any gap.
For work visas and residence permits, public health insurance with TK satisfies Germany’s legal requirements and spares you from private-policy underwriting or exclusions. If you already hold public insurance in another EU country, TK can coordinate recognition or exemption steps to ensure enrollment proceeds smoothly.
Common questions from newcomers
Is TK mandatory for employees?
No specific fund is mandatory, but public insurance is mandatory for most employees under the 73,800-euro threshold, and TK is a popular choice. High earners above the threshold can stay with TK voluntarily.
How much will I actually pay each month?
As an employee, your share is roughly 8.525% of your assessed income up to the contribution ceiling, with your employer paying the same. If you are close to the ceiling, your monthly cost will not exceed the cap.
Can TK help with English and digital services?
Yes. TK offers English information, app-based services, downloadable certificates, an EHIC on your card, and access to the electronic patient record via TK-Safe.
Can my spouse and children be covered for free?
Often yes, if they meet the 2025 income limits and other family-insurance criteria. Mini-jobs have a higher limit. If your spouse is mainly self-employed or privately insured, rules differ—ask TK for a checklist.
I am a student—what do I need?
TK can confirm coverage or exemption directly to your university, and the typical combined student cost quoted in early 2025 is about 145 euros per month.
Practical tips to lower hassle
Start your application a few weeks before your start date or enrollment so your membership certificate is ready for HR or the registrar. If you change status (student to employee, employee to freelancer), notify TK immediately so your contribution basis is correct and gaps don’t arise. Save your TK-App login and enable notifications; it’s the fastest way to receive documents, submit paperwork, and access your ePA. For frequent trips outside the EU, consider a low-cost travel add-on to complement your EHIC.
Germany’s public health system can feel complex, but TK makes it straightforward for immigrants, international students, and global families to meet legal requirements and get dependable care. With transparent 2025 rules—17.05% total contribution split with your employer, a 66,150-euro contribution ceiling, a 73,800-euro compulsory threshold, and clear family-insurance limits—you can budget confidently and focus on your new life. Share your situation (job offer, salary, family details, and start date), and I’ll map out a TK enrollment checklist, estimate your monthly cost, and suggest the fastest path to the certificate your visa, employer, or university needs.
