# Germany → Switzerland: commuters, weekly stayers and full movers

**Why this corridor is different.** Most migration corridors have one population. DE→CH has
three, with completely different tax outcomes: the **Grenzgänger** who lives in Germany and
crosses daily, the **Wochenaufenthalter** who rents a weekday room in Zurich and drives home on
Fridays, and the **full mover** who relocates family and life. People slide between these
categories without noticing — and each slide changes which country taxes your salary, whether
Germany's exit tax fires, and how long German inheritance tax follows you. This Guide maps all
three, because the questions arriving through this corridor mix them constantly.

**Who it's for.** German-resident employees and business owners working in or moving to
Switzerland, and their advisers. It is a rulebook and a trap-map, not advice on your facts —
this corridor combines a bilateral treaty with special Grenzgänger provisions, German
anti-emigration rules, and 26 cantonal tax systems. Have someone who knows both ends check
your plan.

## Part 2 — The Wochenaufenthalter: the accidental Swiss resident

Rent a weekday studio in Basel, keep the family home in Freiburg, drive home Fridays — the
classic *Wochenaufenthalter*. Two systems now both have a claim:

- **Switzerland** will usually treat you as resident for withholding (Quellensteuer) because
  you dwell there during the week.
- **Germany** still treats you as resident because your family home (Wohnsitz / centre of
  vital interests) is there.

The treaty tie-breaker (Art. 4) then decides — and with spouse and children in Germany, the
centre of vital interests almost always keeps **German** residence, with Switzerland taxing
Swiss workdays and Germany applying exemption-with-progression. You are *not* a Grenzgänger
(too many non-return nights), and you have *not* escaped German taxation — you've landed in the
split-taxation middle: Swiss tax on the salary, German progression effect on everything else,
two filing obligations.

**The single most common error on this corridor** is believing the weekday flat alone moved
your tax life to Switzerland. It doesn't — the family home anchors you. Which leads to Part 3.

## Part 3 — The full move: what Germany does when you actually leave

Genuinely relocating — home given up, family across the border — ends ordinary German
unlimited tax liability. Germany, however, has three long-reach rules aimed exactly at moves
to low-tax neighbours:

### 3.1 Wegzugsbesteuerung — the exit tax on shareholdings (§6 AStG)
If you have held **≥1% of a corporation** (GmbH, AG, foreign equivalents) at any point in the
last five years and you have been subject to German unlimited tax liability for (broadly) 7 of
the last 12 years, leaving Germany triggers a **deemed disposal**: German tax on the unrealised
gain in those shares at departure, under the Teileinkünfteverfahren (effectively ~27% of the
gain for individuals).

- Since ATAD implementation (2022), moves to the EU/EEA no longer get the old indefinite
  interest-free deferral — and **Switzerland never qualified** for it anyway. The concession is
  payment in **seven annual instalments**, normally against security, on application.
- Returning to Germany within the statutory window (broadly 7 years, extendable to 12) can
  cancel the tax retroactively if the shares were kept — the "temporary absence" relief. Paper
  the intention *before* leaving.
- Planning happens **before** the move or not at all: reorganising into a partnership
  (Personengesellschaft holding, which is outside §6), gifting stakes early, or simply selling
  first are all pre-departure decisions.

### 3.2 Extended limited tax liability (§2 AStG)
German citizens who were unlimited-liability taxpayers for at least 5 of the last 10 years and
move to a **low-tax territory** while keeping **substantial German economic interests** remain
taxable on an extended catalogue of German-source income for **10 years**. Whether your Swiss
canton counts as "low-tax" is tested numerically (effective burden roughly a third below German
levels, or a privileged regime such as lump-sum taxation — see 4.2, which *automatically*
triggers it). Assume the Finanzamt will ask; structure the answer before departure.

### 3.3 The inheritance-tax shadow (§2 ErbStG)
German citizens remain within **German inheritance and gift tax on their worldwide estate for
5 years after giving up German residence** (extended unlimited liability). Move to Zug in 2026,
gift your portfolio to the children in 2028 — German Schenkungsteuer applies as if you never
left. German-situs assets (real estate above all) stay within German IHT permanently. Since
most Swiss cantons levy **no inheritance tax on spouses and direct descendants**, sequencing
gifts *after* the five-year shadow is one of the largest legitimate wins on this corridor.

---

## Part 4 — The Swiss side: what you're moving into

### 4.1 The ordinary system
- **Three layers** — federal, cantonal, communal — and the canton/commune choice moves your
  total burden by a factor of ~2: the reason "moving to Switzerland" really means "moving to
  Zug, Schwyz, Lucerne… or Geneva".
- **Quellensteuer**: foreign employees on B permits are taxed by withholding; above roughly
  CHF 120k annual salary a mandatory **ordinary assessment** follows (and below it you can
  often opt in — worth modelling, since deductions differ).
- **Wealth tax**: every canton levies an annual net-wealth tax (rates are per-mille, cantonal).
  Trivial next to German income tax for most, material for large liquid estates.
- **No capital gains tax on private movable assets**: sell shares privately and pay nothing —
  the corridor's headline attraction, with one sharp edge: trade too actively (leverage, short
  holding periods, volume) and the assessment flips you to **professional securities dealer**,
  making gains fully taxable income plus social contributions. Real-estate gains are always
  taxed (cantonal Grundstückgewinnsteuer).
- Mandatory **health insurance** (KVG) within 3 months — a cost-of-living line German movers
  consistently underestimate; there is no employer-funded system.

### 4.2 Lump-sum taxation (Pauschalbesteuerung / expenditure-based taxation)
For foreigners who take Swiss residence and **do not work in Switzerland**: taxation on
*expenditure* rather than income — negotiated with the canton, floored by federal minimums
(taxable base of at least ~7× annual housing cost and a six-figure minimum base; several
cantons, including Zurich, have abolished the regime, while Vaud, Valais, Geneva, Ticino and
others keep it). Two German-specific warnings: Germany treats lump-sum-taxed movers as
resident in a **privileged regime**, which switches on §2 AStG's ten-year extended liability
(3.2), and the DBA's own Art. 4(6) can deny treaty benefits to lump-sum taxpayers who aren't
taxed on all Swiss-and-German income at ordinary rates ("modified lump-sum" fixes this —
negotiate it explicitly).

## Part 5 — Sequenced checklist

**Before anything is signed**
1. Classify yourself honestly: commuter, weekly stayer, or mover — and re-test after any home
   office change, family move, or new flat.
2. Shareholders ≥1%: model the §6 AStG exit tax **now**; decide sell / restructure / instalment
   / temporary-absence route before giving notice on the German home.
3. Choose canton and commune with a real comparison — income, wealth tax, and (for
   non-working movers) whether lump-sum is available and worth its German side-effects.

**The move**
4. Deregister (Abmeldung) in Germany only when the facts genuinely support it; keep the
   evidence of the new centre of life (lease, family, schools, clubs, insurance).
5. File the German departure-year return; expect exemption-with-progression mechanics for the
   split year and the §50d attestations your employer needs.
6. Register in the commune, sort the B permit, health insurance within 90 days, AHV number.

**After landing**
7. Grenzgänger/Wochenaufenthalter: set up the non-return-day log and the Gre-certificate
   renewal as annual rituals.
8. Remember the two shadows: 5 years of German gift/inheritance exposure, up to 10 years of §2
   AStG extended liability if German economic interests remain. Calendar both end-dates —
   large gifts and restructurings queue behind them.
9. Watch the professional-trader line if your wealth is in markets, and file the Swiss return
   with the wealth-tax schedule complete — undeclared accounts are what break residence
   arguments retroactively.

## The trap list

| Trap | Why it bites |
|---|---|
| The 61st non-return day | Ends Grenzgänger status for the whole year — taxing rights and withholding recomputed. |
| Weekday flat mistaken for a tax move | Family home in Germany keeps German residence via the tie-breaker; you get *two* filing lives, not one Swiss one. |
| Leaving with a GmbH stake ≥1% | §6 AStG deemed-disposal tax at departure, instalments at best. Discovered after the move, it's just a bill. |
| Gifting within 5 years of leaving | German gift tax on worldwide assets via §2 ErbStG — the Swiss cantonal exemption is irrelevant. |
| Lump-sum regime chosen naively | Triggers §2 AStG extended liability and can void treaty protection unless the modified form is negotiated. |
| Active trading of the "tax-free" portfolio | Professional-dealer reclassification: gains become income plus AHV. |
| Home office drift | Shifts workday geography, Grenzgänger counts, and A1 social-security position — all three, silently. |
