Key points at a glance
- Healthcare professions don’t register a trade (Gewerbe). You notify the Finanzamt (tax office) of your self-employed activity within one month, using the Fragebogen zur steuerlichen Erfassung (tax registration questionnaire) via ELSTER (the tax authorities’ online portal).
- Doctors and psychotherapists are compulsory members of their regional chamber. To treat patients with statutory insurance, they need a KV approval, which, because of needs-based planning, is often only possible by taking over a practice seat.
- Physiotherapists have no chamber. They need the Zulassung under § 124 SGB V (approval by the statutory health insurance funds) and premises that meet the minimum requirements.
- Plan your cover: professional liability insurance, health and long-term care insurance, the Versorgungswerk (professional pension fund) or statutory pension insurance, and registration with the BGW (statutory accident insurer for the health sector) within one week.
- Go online early: your website with an Impressum and your Google profile should be ready before the practice sign goes up.
This post is general information and does not replace legal or tax advice. Rules change – check details with your chamber, your professional association or your tax adviser.
The roadmap: from decision to opening
With a private practice or a physiotherapy practice, you can complete the set-up in six to twelve months. If you want to take over a Kassensitz (practice seat with statutory insurance approval), allow twelve to 18 months, because advertised seats and the meeting dates of the Zulassungsausschuss (admissions committee) set the pace.
18–12 months before: choose your route
A Kassensitz, taking over a practice, joining a Berufsausübungsgemeinschaft (joint practice) or a private practice? Doctors and psychotherapists check the needs-based planning, have themselves entered in the Arztregister (physicians’ register) of their KV (Kassenärztliche Vereinigung, Association of Statutory Health Insurance Physicians) and use the KV’s advice service for setting up a practice.
12–6 months before: approval, premises, financing
Apply for advertised seats and submit a complete approval application before the Zulassungsausschuss meets. Look for premises, clarify the change of use, and finalise your business plan and financing with your bank and tax adviser.
6–3 months before: online presence and liability
Plan your practice name, domain, website and photos. Get quotes for professional liability insurance. Physiotherapists apply for approval under § 124 SGB V as soon as they have the lease and a floor plan of the premises.
3–1 months before: chamber, insurance, equipment
Inform your chamber and the Versorgungswerk, sort out health and long-term care insurance, order equipment, practice software and the connection to the Telematikinfrastruktur (TI, the healthcare data network), and prepare employment contracts for your team.
Opening: notifications with deadlines
BGW within one week, tax office within one month, chamber usually within one month, Gesundheitsamt (public health office) depending on the federal state, pension insurance (physiotherapy) within three months. Verify your Google profile.
The first year
Check your numbers monthly, plan for advance tax payments, get used to billing with the KV or the insurance funds, collect reviews and improve the website based on patients’ first questions.

Approbation, licence and chamber
Every practice is based on the state licence to practise your profession. After that, the three professions differ considerably:
| Profession | Professional licence | Chamber | Patients with statutory insurance | Professional liability insurance |
|---|---|---|---|---|
| Doctors | Approbation (licence to practise medicine, § 2 BÄO) | Compulsory member of the Landesärztekammer (regional medical chamber) | KV approval (§ 95 SGB V), Arztregister with specialist recognition | Required by professional law (§ 21 MBO-Ä and state law); with approval at least €3 million per insured event (§ 95e SGB V) |
| Psychotherapists | Approbation (§ 1 PsychThG) | Compulsory member of the Landespsychotherapeutenkammer (regional chamber of psychotherapists) | KV approval, Arztregister with completed further training or specialist qualification (§ 95c SGB V) | Required by professional law (professional code, state law); with approval at least €3 million (§ 95e in conjunction with § 72 SGB V) |
| Physiotherapists | Permission to use the professional title (§ 1 MPhG) | No chamber | Approval under § 124 SGB V by the working group of the health insurance funds | No statutory minimum sum, but indispensable |
- Chamber: membership arises by law, but you have to register yourself. The deadline is set in the Heilberufe-Kammergesetz (Healthcare Professions Chamber Act) of your federal state and is usually one month after starting your activity, less in some states.
- Gesundheitsamt: in some federal states, you also have to notify the public health office at your practice location when you start working self-employed, e.g. in Hesse within one month (§ 12 HGöGD) or in Bavaria. There, this often applies to physiotherapists too. Ask your Gesundheitsamt.
- Psychologists without an Approbation may practise healing only with a Heilpraktiker licence (alternative practitioner licence) limited to psychotherapy, and may not bill the GKV (statutory health insurance).
Statutory insurance approval, needs-based planning or private practice
Doctors and psychotherapists: KV approval
To treat patients with statutory insurance, you need an approval from the Zulassungsausschuss of your Kassenärztliche Vereinigung (§ 95 SGB V). The prerequisite is entry in the Arztregister. Whether a seat is available is determined by needs-based planning (Bedarfsplanung): if the level of provision for a group of doctors in a planning area exceeds demand by 10 % or more, the area counts as oversupplied and is closed (§§ 101, 103 SGB V). Then you can usually only get in by taking over an advertised seat, where the committee chooses among the applicants.
- Deadlines: the Zulassungsausschuss meets at fixed intervals. Complete applications must be submitted in good time before the meeting; your KV publishes dates and submission deadlines.
- Proof: with your application, you submit the insurance certificate for your professional liability insurance (§ 95e Abs. 3 SGB V).
- Start: in its approval decision, the committee sets the date by which you must start practising (§ 19 Abs. 2 Ärzte-ZV).
Physiotherapists: approval under § 124 SGB V
There is no needs-based planning for Heilmittel (therapeutic services). The working group of the regional associations of the health insurance funds and the substitute funds grants approval if you hold the professional licence, the practice is appropriately equipped and you accept the contracts under § 125 SGB V. Among other things, the nationwide contract requires at least 23 m² of therapy space (one area of 15 m², one of 8 m²) and a clear ceiling height of 2.40 m. With your application, you submit the lease, a floor plan with the areas and a list of equipment.
The alternative: private practice
Without approval, you treat privately insured patients, Beihilfe recipients (civil servants with state healthcare allowance) and self-payers, and bill according to the GOÄ or GOP (fee schedules for doctors and psychotherapists). This is quicker, but requires a clear offer and good visibility. More on this in the guides opening a private practice, setting up a psychotherapy practice and setting up a physiotherapy practice. Psychologists without an Approbation bill privately, see setting up a psychology practice.
Insurance: liability, retirement provision, health insurance, BGW
- Professional liability insurance: for doctors and psychotherapists, it is required by the chamber act and the professional code; for doctors without adequate insurance, the Approbation can even be suspended (§ 6 Abs. 1 Nr. 5 BÄO). With statutory insurance approval, the minimum sum of €3 million per insured event applies. Physiotherapists shouldn’t go without it either, even though no law specifies a sum.
- Versorgungswerk: doctors are compulsory members of the Versorgungswerk of their Landesärztekammer. For psychotherapists, depending on the federal state, there is either a separate Versorgungswerk or affiliation with that of another state; your chamber will tell you which one is responsible.
- Pension insurance (physiotherapy): self-employed physiotherapists without employees subject to compulsory insurance are generally subject to compulsory pension insurance (§ 2 Satz 1 Nr. 2 SGB VI). You must register with the Deutsche Rentenversicherung (German statutory pension insurance) within three months (§ 190a SGB VI).
- Health and long-term care insurance: as a full-time self-employed person, you are no longer compulsorily insured (§ 5 Abs. 5 SGB V). If you had statutory insurance, it automatically continues as voluntary membership, unless you leave within two weeks of being notified by your insurance fund and prove other cover (§ 188 Abs. 4 SGB V). Long-term care insurance follows your health insurance. Consider daily sickness allowance insurance.
- BGW: your practice is a member of the Berufsgenossenschaft für Gesundheitsdienst und Wohlfahrtspflege (statutory accident insurer for health and welfare services). You must register within one week of opening (§ 192 SGB VII), even without employees. Employees are then automatically covered by accident insurance. Self-employed physiotherapists are compulsorily insured themselves (§ 2 Abs. 1 Nr. 9 SGB VII); doctors and psychotherapists are exempt (§ 4 Abs. 3 SGB VII) and can insure themselves voluntarily.
Tax office: a liberal profession, not a trade
Doctors and Krankengymnasten (the traditional German term) or physiotherapists are explicitly listed as liberal professions (§ 18 Abs. 1 Nr. 1 EStG), and psychotherapists count as a similar profession. So you don’t register a trade and pay no trade tax. Instead, you notify the tax office that you have started your activity: with the Fragebogen zur steuerlichen Erfassung, electronically via ELSTER, within one month (§ 138 Abs. 1, 1b and 4 AO). You then receive your tax number.
Medical treatments by doctors, physiotherapists and similar healthcare professions are exempt from VAT (§ 4 Nr. 14 Buchst. a UStG). In return, you generally cannot deduct input VAT on your purchases. So calculate equipment, alterations and your website including VAT.
Premises: change of use, accessibility, hygiene
- Change of use: turning a flat or a shop into a practice is often a change of use requiring a permit under the building code of your federal state. In cities with a Zweckentfremdungsverbot (ban on using housing for other purposes), such as Berlin, Hamburg or Munich, you also need a permit for residential space. Clarify both before signing and have the lease guarantee use as a practice.
- Accessibility: the state building codes require accessibility for publicly accessible buildings in new builds and major alterations. When a Kassensitz is filled again, the needs of people with disabilities are among the selection criteria (§ 103 Abs. 4 SGB V). Under the contract with the insurance funds, new premises for physiotherapy practices should be accessible, and the GKV directory shows this.
- Hygiene: as head of the practice, you are responsible for ensuring that hygiene meets the current state of science (§ 23 Abs. 3 IfSG). Many federal states require hygiene plans for practices performing invasive procedures.

Data protection and confidentiality
- Specially protected data: health data falls under Art. 9 GDPR, plus professional confidentiality (§ 203 StGB). You need a record of processing activities (Art. 30 GDPR) even as a solo practice.
- Data protection officer: mandatory if, as a rule, at least 20 people are permanently involved in the automated processing of personal data or a data protection impact assessment is required (§ 38 BDSG).
- Service providers: data processing agreements (Art. 28 GDPR) with your practice software, online appointment booking, hosting and IT support.
- Documentation: you keep patient records for at least ten years after the end of treatment (§ 630f Abs. 3 BGB).
- Telematikinfrastruktur: practices with statutory insurance approval are connected to the TI (e-prescription, electronic sick note, electronic patient record). Providers of therapeutic services must be connected by 1 October 2027; from 1 January 2027, Heilmittel are prescribed electronically (§ 360 SGB V).
Go online early
Most patients look for their practice online, and privately insured patients and self-payers even more so. Start three to six months before opening:
- Domain and email: a short domain that is easy to spell and an address such as praxis@ihre-praxis.de.
- Website: what patients look for is covered in 12 things for your practice website; what it costs, in the cost comparison.
- Impressum and mandatory information: the requirements differ by profession – for doctors, physiotherapists, psychologists and psychotherapists. The legal notice generator creates the text.
- Advertising: what is allowed is governed by the professional code and the Heilmittelwerbegesetz (Healthcare Advertising Act) – see the posts for doctors, physiotherapy, psychology and psychotherapy.
- Google profile: create and verify it as soon as your address is fixed – step by step in the post on the Google profile.
