Inheriting a Medical Practice: What Your Heirs (Maybe) Will Get

The Gnadenquartal — the countdown almost no doctor knows about

The term sounds like a well-meaning concession. In practice it is a sharp time window. The Kassenaerztliche Vereinigung (Association of Statutory Health Insurance Physicians, KV) may permit the practice to continue to be operated by a substitute after the death of the Vertragsarzt — until the end of the quarter following the quarter of death. In practice that means a maximum of six months, often considerably less.

During this period, three things have to happen. First, a licensed substitute physician must be found to run the practice. Second, the Nachbesetzungsverfahren of the KV must be applied for and completed — with all formal hurdles. Third, a buyer must be found to take over the advertised seat. In blocked planning areas, the KV's admission committee decides on the selection — the heir has no right to nominate here.

That is the central point: the seller has no voting right in the Nachbesetzungsverfahren. You cannot decide who takes over the seat. You cannot choose the highest bidder. The KV decides — according to criteria such as suitability, supply situation and the order of applications.

The Federal Social Court ruled in its judgment of 11 December 2013 (case no. B 6 KA 49/12 R) that the admission of a doctor by way of practice succession requires the existence of a viable, continuable practice. The point in time when the re-appointment is applied for is decisive. Anyone who lets the Gnadenquartal expire without filing the application with the KV loses not only the KV seat — they also lose the right to the entire Nachbesetzungsverfahren.

In rural areas, an additional problem arises: in areas of undersupply, there are often simply no applicants. Around 12.5 per cent of all general-practitioner practices today are considered effectively unsellable. Anyone who dies there leaves an asset that no one will ever lift.

The Federal Social Court tightened this further in its decision of 5 June 2013 (case no. B 6 KA 2/13 B): in the case of long-lasting non-exercise of contract-physician activity, the practice value can be reduced or fall away entirely. In the decided case, a psychotherapist had not treated any patients for over four years — the continuable practice was no longer present, the claim for advertising the seat failed. Translated to the death event (Erbfall): if no substitute arrangement is in place and the practice stands idle for months, the patient base lapses — and with it the economic core of the practice value.

Practice case from my consultations: internist practice after a stroke

An anonymised case from my doctor clientele in the Frankfurt area illustrates the pattern in concrete terms. A 58-year-old internist with a sole solo practice (around 1,400 cases per quarter, practice value estimated at 480,000 EUR plus inventory of 80,000 EUR) suffered a severe stroke in 2024. The widow was a teacher, the two daughters were studying architecture and law — no Approbation in the family. No one knew the first thing about the practice.

Three phases ran in parallel. In the first two weeks, the family searched for a substitute themselves — through professional networks, KV enquiries, a friendly colleague. The KV referred to the formal application procedure but held back on the search for applicants. We were brought in in week three. First measure: a written Vertreterregelung with a neighbouring internist BAG for six months, free of charge for patient care, fees paid out of running KV settlements. Second measure: an immediate application for the Nachbesetzungsverfahren before the admission committee, together with a valuation report under the modified income-capitalisation method. Third measure: targeted outreach to applicants via the KV and a practice-brokerage specialist.

The result after six months: three applicants, a sale to a young internist from the MVZ sector at 410,000 EUR (around 85 per cent of the valuation report — written down because of the three-month substitute phase and the slight drop in patient numbers). Had we lost those first three weeks, the patient base would have declined by a further 35 per cent according to KV data — the practice value would have fallen to 220,000 to 260,000 EUR. The difference: around 180,000 EUR rescued, by the early substitute mandate and the timely KV application alone.

In my work with doctor clients (Mandanten), this is the single most common mistake: the family starts the search for applicants before securing the practice substitution. Both steps running in parallel are the only way to use the Gnadenquartal meaningfully at all.

The Berufstraegerklausel — why your children often cannot take over the practice

A further doctor-specific mechanism: the Musterberufsordnung of the Bundesaerztekammer (model professional code of the Federal Medical Association, MBO-AE) and contract-physician law only allow medical activity to be carried out by Approbierte (holders of a German Approbation). That means: even if your children legally become the heirs of your practice — they may only practise it if they are doctors themselves.

What many people consider a solution — a silent participation of the non-licensed child in the practice — is not permitted under professional law. Non-professionals may not share in the income from medical activity. That excludes indirect structures too.

The Gleichstellungsgelder trap

The usual solution in doctor families with mixed children (one child a doctor, one child not) is the so-called Gleichstellungsgelder. The licensed child takes over the practice, the non-licensed child receives a sum of money in equivalent amount. So far, so logical.

A trap arises here for tax purposes that costs many families six-figure additional burdens: if the Gleichstellungsgelder are paid directly from the licensed sibling to the non-licensed sibling, they fall into Schenkungsteuerklasse II (gift-tax class II for German inheritance and gift tax). The Freibetrag is only 20,000 euros instead of 400,000 euros per parent. With an equalisation sum of 300,000 euros, 60,000 to 80,000 euros of gift tax can quickly arise that would not have been incurred at all under correct structuring.

The correct approach: the parents make lifetime Schenkungen to the non-licensed child equal to the later practice transfer. These gifts fall into tax class I with a 400,000-euro Freibetrag per parent and are renewable every ten years (§ 14 ErbStG). With two parents and staggered gifts, often 800,000 euros per child can be transferred tax-free.

Three structures that secure the practice value for the family

There is no single step that covers all risks — but three structural building blocks that should be set up jointly in every doctor's family.

Building block 1: Testament with a practice clause and an executor

A simple Berliner Testament (joint spousal will under § 2269 BGB) is not enough for a medical practice. You need an explicit practice clause that governs:

• who manages the practice as trustee until a licensed successor is found
• what powers the executor receives (KV application, choice of substitute, sales negotiation)
• the ratio in which the practice value and the remaining assets are divided among the heirs — particularly when not all children are doctors

The executor should ideally be someone with sector knowledge: a Steuerberater (German tax advisor) with doctor clients or a specialised lawyer. §§ 2197 ff. BGB governs the appointment; the practice-specific executorship itself has to be clearly defined so that the Gnadenquartal is not lost to internal disputes between the heirs.

Building block 2: KV power of attorney and substitute arrangement during the owner's lifetime

An emergency plan that does not only kick in upon the death event: you deposit a Vollmacht with the KV that automatically activates a prepared substitute arrangement in the event of sudden incapacity to work or death. Ideally you have a substitute agreement pre-arranged with two or three collegial practices — in writing, with a fee arrangement, KV-compliant.

This prevents the first weeks of a crisis being lost to the family having to search, vet and negotiate. In practice those are the most precious weeks of the Gnadenquartal.

Building block 3: Lifetime gift to a licensed child plus Gleichstellungsgelder

If one of your children is a doctor and will take over the practice: hand it over during your lifetime, not only upon death. This has three advantages:

• The relief provisions of § 13a ErbStG and § 13b ErbStG also apply to freelance practices as begünstigtes Vermoegen (favoured business assets) — if the retention period is complied with, 85 or 100 per cent of the practice is exempt from tax.
• The donor generation can actively control the handover design instead of trusting the death event.
• Gleichstellungsgelder to non-licensed siblings are correctly paid from parents to children (tax class I, high Freibetrag), not from siblings to siblings (tax class II, low Freibetrag).

When selling the practice during your lifetime: saving 70,000 to 80,000 euros in tax

If you sell the practice to an external successor instead of transferring it within the family, two tax instruments are decisive.

First: § 16 Abs. 4 EStG grants sellers from the age of 55 or in case of permanent incapacity to work a one-off Freibetrag of 45,000 euros on the capital gain. Anyone who sells before the age of 55 loses it.

Second: the Fuenftelregelung under § 34 EStG (one-fifth rule for extraordinary income) spreads the capital gain notionally over five years and significantly reduces tax progression. With a practice value of 500,000 euros and a top tax rate of 42 per cent, the Fuenftelregelung can push the effective tax rate down to around 25 to 28 per cent — a saving of 70,000 to 80,000 euros compared to standard taxation.

Example calculation: a doctor sells their practice for 500,000 euros at age 58. Book value 50,000 euros, capital gain 450,000 euros. With the Freibetrag (§ 16 Abs. 4 EStG): 405,000 euros remain to be taxed. With the Fuenftelregelung instead of the full top tax rate: around 113,000 euros tax instead of around 190,000 euros — a saving of around 77,000 euros. Anyone selling the same practice at age 53 loses the Freibetrag — the tax rises by around 19,000 euros.

The Federal Social Court ruled in its judgment of 14 December 2011 (case no. B 6 KA 39/10 R): there is no room for the admission committees to set the market value of a practice if the outgoing Vertragsarzt has reached agreement with all applicants on a purchase price. In the event of disputes, the modified income-capitalisation method is the benchmark. For the heir family this means: anyone who finds a buyer by mutual consent holds the valuation monopoly — the KV selection remains formal, the purchase-price negotiation is free.

Takeover or death event — intent makes the difference

Anyone googling "taking over a medical practice" is rarely searching for the death event. From the buyer's perspective, what counts is the valuation methodology (modified income-capitalisation method following the BSG benchmark), financing (Hausbank versus apoBank versus seller loan), the availability of a contract-physician seat in the planning area, and the tax treatment of goodwill (depreciation over three to five years following BFH (Bundesfinanzhof, the Federal Fiscal Court) case law on practice goodwill as an intangible asset). For the heir side: the more structured the handover is prepared, the higher the chance of a good purchase price — the buyer's perspective is therefore relevant for the seller family too. We address the buyer path in the spoke article Taking over a medical practice 2026: valuation, financing, KV procedure.

The special case of the MVZ GmbH: tax advantage or tax trap?

Some doctors consider setting up an MVZ GmbH (Medizinisches Versorgungszentrum, a medical care centre as a GmbH (private limited company under German law)). Tax-wise it is attractive: instead of 42 per cent income tax, the GmbH only pays around 15 per cent corporate income tax plus solidarity surcharge — if profits are retained. The limitation of liability is also an argument.

What many overlook: the limitation of liability does not apply to the doctor's own professional treatment errors — they continue to be personally liable under the medical contract. In addition, many MVZ GmbHs operate as a guarantee construction towards the KV, which undermines the limitation of liability in practice. The MVZ GmbH is a tool for specific constellations — not the blanket cure-all it is sometimes sold as.

What you should do now

If you are a doctor in private practice, check four points:

1. Practice emergency plan: do you have a written KV power of attorney and an agreed substitute physician? If not: that is point one for the next two weeks.
2. Testament with a practice clause: have you regulated by Testament what should happen to the practice — including an executor with sector knowledge? If your Testament is based on a template: it does not suffice for a practice.
3. Marriage contract with a practice clause: would the goodwill of your practice fall into the Zugewinnausgleich (equalisation of accrued gains under German matrimonial property law) in case of divorce? For practices worth 400,000+ euros, a modified marriage contract protects the practice and provides for the spouse in another way.
4. Timing of the sale: if you are near 55 and considering a sale — the right sequence of steps (Freibetrag, Fuenftelregelung, practice closure versus sale) decides about five- to six-figure amounts.

Frequently asked questions

What is the Gnadenquartal for a medical practice?

The Gnadenquartal is the time which the Kassenaerztliche Vereinigung grants to the heirs of a deceased Vertragsarzt in order to have the practice continued by a substitute, to find a licensed successor and to initiate the Nachbesetzungsverfahren. It usually ends with the end of the quarter following the quarter of death — so a maximum of six months, often considerably less.

Can my non-licensed children inherit and continue my medical practice?

Inherit yes, continue no. The practice does pass to the heirs as inheritance (§ 1922 BGB), but the right to exercise medical activity is tied to the Approbation. A silent participation of non-professional heirs in the practice income is also not permitted under professional law. The practice therefore has to be either sold or taken over by a licensed heir — or the KV seat lapses.

How big is the tax saving on selling the practice under § 16 and § 34 EStG?

In a typical practice sale with a price of 500,000 euros and a book value of 50,000 euros (capital gain 450,000 euros), § 16 Abs. 4 EStG yields a Freibetrag of 45,000 euros from age 55. § 34 EStG (Fuenftelregelung) additionally reduces tax progression. The total saving is typically between 70,000 and 80,000 euros compared to standard taxation at the top rate.

What is the Berufstraegerklausel and when does it apply?

The Berufstraegerklausel is the rule from the Musterberufsordnung of the Aerztekammer (§ 18 MBO-AE) and contract-physician law that only licensed doctors may run a practice. It applies to every practice transfer — whether by inheritance, gift or silent participation. Non-professional heirs or co-owners are excluded.

What provision rules exist for non-licensed family members of a deceased doctor?

If the spouse or the children are not licensed, Gleichstellungsgelder or proceeds from the practice sale have to secure their provision. A life insurance policy with a beneficiary clause in favour of the family, powers of attorney for care decisions and an executor with sector knowledge are the standard building blocks. Early Schenkungen to licensed children with Gleichstellungsgelder to non-licensed siblings are often the most tax-efficient solution.
