There is a small flowchart that determines a quarter of your German tax bill for the rest of your career. You meet it on day one of your first job: the box on the onboarding form that asks "Public or private insurance?". Most expats tick whatever a colleague recommends. The decision is much bigger than that, and the rule that makes it big is the one nobody mentions: after age 55, you cannot move back.
Who Even Has a Choice
In Germany, health insurance is mandatory under §193 of the Versicherungsvertragsgesetz (VVG). You must be insured. The choice of which kind is gated by three categories.
Employees earning under €77,400/year (2026)
You are in GKV by law. No choice. The Jahresarbeitsentgeltgrenze (JAEG) for 2026 is €77,400 gross per year (€6,450/month). The number ratchets up most years; 2025 was €73,800. You can buy a supplementary private policy on top (Zusatzversicherung), but your base must be GKV.
Employees earning above €77,400/year
You can choose between GKV and PKV. You only get this choice once you have earned above the threshold for a full calendar year. A single high-paying month does not flip you out of GKV obligation.
Freelancers, self-employed, civil servants
You can choose from day one, independent of income. Civil servants (Beamte) get a partial state subsidy (Beihilfe) that makes PKV strongly favored. Freelancers default into PKV in most income brackets because GKV applies a minimum assumed income.
The Cost Picture in 2026
Concrete numbers from public sources, all valid as of January 2026.
GKV (public)
- Contribution rate: 14.6% of gross income, plus a provider-specific Zusatzbeitrag.
- Zusatzbeitrag 2026: TK 2.69%, Barmer 3.29%, DAK 2.80%, AOK varies by Land 2.50%-3.50%.
- Total 2026 contribution: 17.29% to 17.89% of gross.
- Cap: contributions stop accruing above the Beitragsbemessungsgrenze (€66,150/year in 2026). After that, you pay a flat €477-€493 per month no matter your salary.
- Split: employer pays roughly half. Your share is half the percentage, capped at the same ceiling.
- Family: spouse (if under €565/month earnings) and children are insured for free.
PKV (private)
- Premiums are set per person, per age, per health status at signup.
- Single under 30 with no pre-existing conditions: €280-€450/month for full coverage.
- Single 35-45: €450-€700/month.
- Single 55+: €700-€1,200/month, climbing yearly.
- Family: each member needs a separate policy. A couple with two children can hit €1,800-€2,500/month combined.
- Employer share: 50% of premium up to half the equivalent GKV cap (€477 in 2026). Anything above that, you pay out of pocket.
The break-even math
For a 30-year-old single earning €90,000 gross with no dependents and no pre-existing conditions, PKV is cheaper by €200-€350 per month in 2026. For the same person at 45 with a partner and two kids: GKV is cheaper by €600-€1,000 per month. (How-to-Germany on GKV vs PKV 2026)
The Five Questions That Actually Decide
Ignore the marketing on either side. Five questions determine the right choice.
1. How long are you staying in Germany?
PKV is a long-term contract optimized for people who will be in Germany for decades. If you might leave within five to ten years, PKV's age-based premium and cash-back structures are wasted on you. Pick GKV.
2. Do you have or plan to have a family?
GKV covers spouse (income under €565/month) and children free. PKV charges per head, including newborns from day one. For a couple with two kids, the family difference can be €1,500+ per month. Pick GKV.
3. Are you over 40?
PKV premiums climb every year you age in the system. Joining PKV at 25 with thirty years ahead of you is one math problem. Joining at 42 is a different one, because you are signing up for the steepest part of the curve. Pick GKV over 40 unless your salary is very high and you plan to retire abroad.
4. Do you have any pre-existing condition?
PKV insurers underwrite on signup. Pre-existing conditions raise premiums by 10-50% or trigger exclusions. GKV cannot discriminate by health status under §3 SGB V. Pick GKV if any chronic condition is on your medical record.
5. Can you accept a one-way door at 55?
PKV-to-GKV switching after 55 is effectively impossible under §6 SGB V. If your career, family situation, or savings change at 55+, GKV may not be available. PKV premiums at retirement age can hit €1,500-€2,500 per month. This is the single most important consideration. (Findenglish on the 55-switch rule)
The Decision Tree
START
│
├─ Salary under €77,400/year (or freelancer below €60k)?
│ └─ GKV (legally required for employees; default for low-income freelancers)
│
├─ Family planned or current spouse/kids?
│ └─ GKV (family insurance saves €1,000+/month)
│
├─ Over 40 OR any chronic condition?
│ └─ GKV (PKV underwriting hurts you)
│
├─ Might leave Germany within 10 years?
│ └─ GKV (PKV long-term math wasted)
│
├─ Civil servant (Beamter) with Beihilfe?
│ └─ PKV (state pays 50-70%; classic choice)
│
├─ Single, under 30, healthy, earning >€95k, committed to Germany?
│ └─ Consider PKV (only here does the math really work)
│
└─ Anywhere else: GKV
What GKV Actually Covers (and Doesn't)
In one paragraph. GKV pays for: GP visits, specialist visits with a referral, hospital stays in shared rooms, generic-tier prescriptions with a €5-€10 co-pay capped at €10/month, basic dental (cleaning, fillings, root canals deemed necessary), psychotherapy (up to 50 sessions/year, see related field-notes piece), pregnancy and birth, and most preventive care.
GKV does not fully cover: ceramic crowns and implants (you pay the difference above Festzuschuss, see related dental field-notes), private hospital rooms, named-doctor treatment, glasses for adults (only one €10-€30 prescription frame allowance), most alternative medicine, business-class evacuation insurance.
The gaps are predictable. A €20/month Zahnzusatzversicherung (dental top-up) plus a €10/month Krankenhauszusatz (hospital top-up) covers most of what GKV does not, for under €30/month, and you keep all the GKV protections.
What PKV Covers Better (the real arguments)
The genuine PKV advantages, not the marketing:
- Faster specialist appointments. GKV patients wait 3-12 weeks; PKV patients often get appointments within days. Berlin specialist wait times for orthopaedics, dermatology, and gynaecology are significantly lower with PKV.
- Private hospital rooms by default. Two-bed minimum, often single rooms in good hospitals.
- Treatment by the Chefarzt (head physician). Standard option in many PKV plans.
- Coverage abroad. Most PKV policies cover non-emergency care worldwide; GKV covers emergency only in EU and select treaty countries.
- Free choice of doctor in private practice. Some specialists only see PKV patients.
What Happens If You Just Arrived
Most expats hitting Germany for the first time should default to GKV in the first six to twelve months for three reasons.
- The Anmeldung and Aufenthaltstitel chain assumes GKV registration is fast and frictionless. PKV signup adds a medical underwriting step that can take weeks.
- Your German salary in year one rarely clears €77,400 plus you have not been on it for a full year, so PKV is not even an option for most employees in their first year.
- GKV lets you reverse the decision easily. You can switch to PKV in year two or three. Going the other direction is much harder.
The exceptions are: freelancers planning a long German career, civil servants with Beihilfe, and senior executives with confirmed multi-year contracts above the threshold.
How to Actually Sign Up for Each
GKV (online, 24-72 hours)
Pick a Krankenkasse: TK, Barmer, AOK, DAK, Techniker. All offer English signup pages. Fill out the online form with your Anmeldebestätigung, passport, employer name, and predicted income. They send a digital Mitgliedsbescheinigung (membership certificate) you forward to your employer or the Ausländerbehörde.
PKV (broker, 2-6 weeks)
PKV signup runs through an insurance broker because comparing the 30+ providers is nontrivial. Reputable English-speaking brokers in 2026: Feather, Ottonova (digital-first PKV), private-insurance-germany.de, TheGoodBroker. You answer a health questionnaire, the broker shops your profile, you sign with the chosen insurer.
What to Compare on the ExpatNav Health Insurance Comparison Page
We list 6 providers across GKV (TK, Barmer, AOK) and PKV (Feather, Care Concept, MAWISTA, Ottonova). Filter by:
- Nationality + visa type (some PKV providers reject non-EU)
- English-language support and apps
- Whether the provider accepts pre-existing conditions
- Family-friendly tiering
- Monthly cost at your specific income and age
The One-Line Rule
If you are reading this and not sure: pick GKV. GKV is fully reversible. PKV is functionally one-way. The right time to consider PKV is year three of your German career, after a tax return shows a clean 12-month income above €77,400, with a broker who runs the numbers for your specific age, family, and health.
