- Sole traders fall under the Entstrickung (de-recognition tax under § 4 Abs. 1 Satz 3 EStG when business assets leave German taxing rights) rules of § 4 Abs. 1 Satz 3 EStG — § 6 AStG (Wegzugsbesteuerung for corporations) does NOT apply to them
Sole traders face a different tax problem on the Wegzug than GmbH shareholders. The Wegzugsbesteuerung under § 6 AStG does NOT apply to them — they hold no shares in a corporation. Instead, the Entstrickung under § 4 Abs. 1 Satz 3 EStG applies, which can be economically just as expensive.
Anyone leaving Germany as a liberal professional or sole trader risks the uncovering of all hidden reserves in their business — goodwill, client base, tangible assets. The tax office deems a sale that never took place. A domestic Betriebsstaette is the most important lever for avoiding it.
How does the Entstrickung work in sole proprietorships?
The Entstrickung under § 4 Abs. 1 Satz 3 EStG applies when an asset leaves Germany's taxing rights. Specifically: when the asset remains in business assets, but is no longer within German reach — typically through relocation of the business abroad or through giving up unlimited tax liability.
That is exactly what happens with a sole trader's Wegzug: the business — law firm, medical practice, online shop, coaching practice — moves abroad with its owner. The German authorities lose ongoing taxation. The consequence: the hidden reserves are "de-recognised" (entstrickt) on the Wegzug and taxed.
Hidden reserves are the difference between fair market value and book value. For a law firm with EUR 1.5 m goodwill and EUR 50,000 of tangible assets on the balance sheet, the hidden reserve amounts to around EUR 1.45 m. At the top tax rate plus solidarity surcharge that produces tax of around EUR 650,000 — immediately, without any actual sale.
When does the Entstrickung NOT apply?
The Entstrickung is avoided if the asset remains subject to German taxing rights. Three classic constellations:
- A domestic Betriebsstaette is preserved. The business is continued in Germany — for example through a permanent place of business that the leaver continues to run themselves or that they transfer to a managing director.
- Structural change before the Wegzug. Contribution of the Einzelunternehmen into a GmbH (§ 20 UmwStG, book-value contribution possible). The GmbH shares then fall under § 6 AStG — which, given the low book values on contribution, is often cheaper than the Entstrickung.
- Transfer to domestic successors. Sale or Schenkung (lifetime gift) of the business before the Wegzug to a purchaser remaining in Germany. The hidden reserves are then taxed at the purchaser's level — not the leaver's.
What is a domestic Betriebsstaette?
A Betriebsstaette under § 12 AO is any fixed place of business that serves the activity of a business. This covers:
| Type of Betriebsstaette | Likelihood of recognition |
|---|---|
| Business premises with staff | very high |
| Own management offices | high |
| Warehouse with own staff | high |
| Server / IT infrastructure with maintenance | medium |
| Co-working place with a fixed booking | medium |
| Bare postal address | very low |
| Letterbox company | not recognised |
In practice the requirements are substantive. A bare letterbox address or a virtual office without real business activity is not enough. The tax office tests the economic substance — rooms, staff, actual business handling.
A lawyer who continues to run their firm in Germany (with employed lawyers, a secretariat, mandates) and personally moves to Spain has a genuine Betriebsstaette — Entstrickung does not apply. A coaching online shop without any German infrastructure, by contrast, has no Betriebsstaette — Entstrickung applies in full.
Step by step: a sole trader planning the Wegzug in 6 stages
- Valuation of the business. Goodwill, client base, tangible assets, intangible assets (trademarks, software) — document all hidden reserves.
- Test structuring options. GmbH contribution, Betriebsstaette solution, sale to a successor — depending on sector and assets.
- Plan the timeline backwards. Structural change and book-value contribution take 1 to 2 years. Three years of lead time is realistic.
- Set up the Betriebsstaette or carry out the structural change. Operational implementation depending on the chosen strategy.
- Analyse the destination country for tax purposes. DBA treatment of freelance income (often the source-state principle), withholding tax, social security.
- Carry out the Wegzug operationally. Deregistration of residence, new residence abroad, clean documentation of the Betriebsstaette.
Structural change: contributing the sole proprietorship into a GmbH
The contribution of a sole proprietorship into a GmbH under § 20 UmwStG is the standard route before the Wegzug. Advantages:
- Book-value contribution possible (no uncovering of hidden reserves on contribution)
- Hidden reserves are "parked" in the GmbH — the Wegzug only triggers § 6 AStG for the GmbH shares
- GmbH shares can be transferred in a structured way after the Wegzug
- Seven-year holding period for book-value contributions to be observed (§ 22 UmwStG)
Worked example: a law firm with EUR 1.5 m in hidden reserves. On Entstrickung, around EUR 650,000 of tax is due immediately. On contribution into a GmbH and a later Wegzug, § 6 AStG applies — but the fair market value of the GmbH shares matches the former goodwill, and the acquisition cost equals the contribution. Economically a similar burden, but: through Holding contribution, Schenkung to family or the Rueckkehrerregelung the tax can then be reduced.
The structural change works as a reallocation effect rather than a direct avoidance — it opens the door to the Wegzugsteuer avoidance strategies for corporate shareholders.
Comparative calculation: with and without structuring
Starting position: a liberal professional (lawyer), aged 48, a firm with EUR 1.5 m goodwill, planning a Wegzug to Portugal in 3 years.
| Scenario | Strategy | Tax burden on Wegzug |
|---|---|---|
| Spontaneous Wegzug | None | EUR 650,000 Entstrickung immediately |
| Betriebsstaette | Firm stays in DE | EUR 0 Entstrickung |
| GmbH contribution 3 years earlier | § 20 UmwStG | approx. EUR 420,000 Wegzugsteuer on the GmbH shares |
| + Schenkung to the daughter | § 16 ErbStG, before the Wegzug | approx. EUR 100,000 Wegzugsteuer (remaining stake) |
| + intention to return 7 years | § 6 Abs. 3 AStG | EUR 0 (retrospectively on return) |
A liberal professional who leaves without structuring pays almost half a million more than with clean preparation. For larger practices or online businesses, the difference can be seven figures.
Frequently asked questions
Does the Wegzugsteuer under § 6 AStG also apply to sole traders?
No. § 6 AStG only governs the Wegzug for participations in corporations (GmbH, AG). Sole traders fall under the Entstrickung rules of § 4 Abs. 1 Satz 3 EStG. Economically the burden can be just as high, however, because hidden reserves are uncovered and taxed.
What is a domestic Betriebsstaette?
A fixed place of business in Germany that continues to serve the business activity after the Wegzug (§ 12 AO). Specifically: rooms with staff, own management, warehouse with employees. Bare postal addresses or virtual offices are not enough.
Is a postal address enough as a Betriebsstaette?
No. The tax office tests the economic substance. A pure postal address, a virtual office without real business activity or a letterbox company are not recognised as a Betriebsstaette. Real rooms with staff or own management are required.
What is Entstrickung under § 4 Abs. 1 Satz 3 EStG?
Entstrickung is the deemed uncovering of hidden reserves when an asset leaves German taxing rights — typically on a sole trader's Wegzug abroad. The difference between fair market value and book value is taxed immediately.
Can I avoid the Entstrickung through a GmbH contribution?
The GmbH contribution shifts the tax problem from the Entstrickung to § 6 AStG (Wegzugsbesteuerung on GmbH shares). Economically often similar, but: for GmbH shares there are avoidance routes (Holding, Schenkung, Rueckkehrerregelung) that do not work for sole proprietorships.
What about liberal professionals?
Liberal professionals (lawyers, doctors, architects, consultants) are regularly sole traders in tax terms. The Entstrickung applies to them in the same way. Goodwill of the liberal professions (client base, practice value) is often the largest item in the valuation — and therefore the largest hidden reserve.
How long does the GmbH contribution take?
Pure formation and contribution: 3 to 6 months. BUT: the book-value contribution under § 20 UmwStG has a seven-year holding period — anyone who relocates or sells the shares within that time risks subsequent taxation. Clean lead time: at least 3 years to the Wegzug, ideally 5 to 7 years.
