Swiss Bitcoin holders worry about the wrong tax. Capital gains get the headlines. Death gets the bill.
I work in the crypto self-custody space. The Zurich answer is statutory and often surprising to people who assume inheritance tax mirrors wealth tax. Spouses owe nothing. Children owe 2 to 6 percent on a tiered scale. Bitcoin gets valued at one government rate. None of it is discretionary.
This post covers Zurich only. Federal rules and other cantons differ. If you hold a multi-million CHF position, read to the end. The tiered math compounds fast.
TL;DR
Under ZH Erbschaftssteuergesetz (ESchG) §17, surviving spouses and registered partners pay zero inheritance tax in Zurich, regardless of the Bitcoin estate size. Direct descendants (children, grandchildren) pay a tiered rate under ZH ESchG §19: 2% up to CHF 200K, 3% from CHF 200K to CHF 500K, 4% from CHF 500K to CHF 1M, 6% above CHF 1M, per heir. Switzerland levies no federal inheritance tax (DBG Art. 44). Bitcoin is valued at the ESTV Kursliste rate on the date of death. Disclosure of digital asset holdings in the Erbschaftsinventar is legally required under AMLO-FINMA Art. 51.
No federal inheritance tax exists in Switzerland
Start here. DBG Art. 44 excludes inheritances from federal income tax. Switzerland has no federal Erbschaftssteuer. You are navigating cantonal law only.
Each of the 26 cantons sets its own rates, exemptions, and brackets. Zug exempts direct descendants entirely. Zurich does not, but it sits far from the most punitive end. Knowing the federal layer is zero lets you focus on the Zurich statute.

Zurich inheritance tax rates by relationship
ZH ESchG structures rates by the heir's relationship to the deceased. Closer relationship, lower or zero rate.
Spouses and registered partners: exempt. ZH ESchG §17 grants a full exemption with no cap. A surviving spouse inheriting CHF 10 million in Bitcoin pays zero Erbschaftssteuer in Zurich. §17a extends the same logic to registered civil partnerships.
Direct descendants (children, grandchildren): tiered rates. ZH ESchG §19 applies a progressive bracket structure per heir:
| Taxable inheritance per heir | Rate |
|---|---|
| Up to CHF 200,000 | 2% |
| CHF 200,001 to CHF 500,000 | 3% |
| CHF 500,001 to CHF 1,000,000 | 4% |
| Above CHF 1,000,000 | 6% |
The rates apply to each heir's individual share, not to the total estate. A CHF 2M estate split between two children creates two CHF 1M assessments, not one CHF 2M assessment.
Siblings: 6% to 18%. Non-direct-line relatives pay materially more under ZH ESchG §20. If your Bitcoin is going to a sibling rather than a child, the tax treatment is categorically different. Plan accordingly.
Non-relatives and unmarried partners: up to 36%. Without a registered partnership or marriage, an unmarried partner has no exemption under Zurich law. Bitcoin left to a long-term partner triggers the top bracket. Swiss Erbrecht also limits such bequests through Pflichtteil rules, which reserve a mandatory share for direct heirs.
How Bitcoin is valued for Zurich estate tax
The ZH Steuerverwaltung does not accept exchange screenshots, portfolio app exports, or self-assessed figures. The official valuation basis is the ESTV Kursliste reference rate on the date of death, published by the Federal Tax Administration.
The deceased held 2 BTC. They died on a date when the ESTV Kursliste listed CHF 95,000 per Bitcoin. The taxable estate value for those 2 BTC is CHF 190,000. The calculation is mechanical. You can pull the rates from estv.admin.ch.
For Bitcoin held at a Swiss custodian (Sygnum, Crypto Finance, or similar), the custodian provides a balance statement on the date of death. The cantonal authority cross-references it against the ESTV rate. For self-custody holdings, the estate executor identifies wallet addresses and computes the CHF value using the ESTV rate.
One practical problem sits underneath all this: hardware wallets with lost or undisclosed seed phrases make the inventory impossible to complete accurately. The Bitcoin is technically in the estate but is unrecoverable. For the access-protocol mechanics that prevent this, the Bitcoin Taxes Switzerland chapter covers the disclosure side.
Three worked estate scenarios with full ZH math
Scenario A: CHF 500,000 Bitcoin estate, surviving spouse and two children
Deceased: Zurich resident, 3.2 BTC valued at CHF 500,000 at date of death (ESTV Kursliste rate).
Heirs: spouse (50% share = CHF 250,000) + two children (25% each = CHF 125,000 each).
Zurich Erbschaftssteuer:
- Spouse: CHF 0 (§17 full exemption)
- Child 1: CHF 125,000 at 2% = CHF 2,500
- Child 2: CHF 125,000 at 2% = CHF 2,500
Total Erbschaftssteuer: CHF 5,000 on a CHF 500,000 Bitcoin estate. At this size the spouse exemption dominates.
Scenario B: CHF 2,000,000 Bitcoin estate, two children only (no surviving spouse)
Deceased: Zurich resident, 12.9 BTC valued at CHF 2,000,000. No surviving spouse. Two children inherit equally: CHF 1,000,000 each.
Zurich Erbschaftssteuer per child, applying ZH ESchG §19 brackets:
| Bracket | Applies to | Rate | Tax |
|---|---|---|---|
| First CHF 200,000 | CHF 200,000 | 2% | CHF 4,000 |
| CHF 200,001 to CHF 500,000 | CHF 300,000 | 3% | CHF 9,000 |
| CHF 500,001 to CHF 1,000,000 | CHF 500,000 | 4% | CHF 20,000 |
Per child: CHF 33,000. Total for two children: CHF 66,000.
No amount falls into the 6% bracket. Each child's share is exactly CHF 1,000,000, which is the top of the 4% bracket. The 6% bracket activates only above CHF 1,000,000 per heir.
Scenario C: CHF 10,000,000 Bitcoin estate, two children only
Deceased: Zurich resident, 64.5 BTC valued at CHF 10,000,000. Two children inherit equally: CHF 5,000,000 each.
Zurich Erbschaftssteuer per child:
| Bracket | Applies to | Rate | Tax |
|---|---|---|---|
| First CHF 200,000 | CHF 200,000 | 2% | CHF 4,000 |
| CHF 200,001 to CHF 500,000 | CHF 300,000 | 3% | CHF 9,000 |
| CHF 500,001 to CHF 1,000,000 | CHF 500,000 | 4% | CHF 20,000 |
| Above CHF 1,000,000 | CHF 4,000,000 | 6% | CHF 240,000 |
Per child: CHF 273,000. Total for two children: CHF 546,000.
The 6% bracket now dominates. Combined Erbschaftssteuer is 5.46% of the total estate value, driven by the share sitting in the top bracket.
The critical threshold sits at CHF 1,000,000 per heir. Once any heir's share crosses that line, 6% applies to everything above it. A CHF 10M Bitcoin estate split between two children produces a materially different outcome than the same estate split among four children, because spreading the inheritance pulls each share down out of the 6% band.
Disclosure obligations under AMLO-FINMA Art. 51
Digital asset inheritance carries a disclosure dimension most asset classes do not. AMLO-FINMA Art. 51 sets reporting thresholds for inherited digital assets. Heirs who receive Bitcoin via estate proceedings must include it in the Erbschaftsinventar submitted to the cantonal authority.
The inventory must identify all wallet addresses, the exchange accounts (including foreign exchanges), the ESTV Kursliste CHF valuation, and the basis for that valuation. Omitting self-custody Bitcoin from the inventory is not a grey area. The asset exists on a public blockchain. It is findable.
Custodians (Swiss banks, licensed exchanges) holding Bitcoin for the deceased get notified by the cantonal authority as part of standard estate proceedings. They freeze the account until inheritance is resolved. For self-custody holdings, the executor reconstructs the wallet inventory from the deceased's records.
This is the operational argument for structured estate planning while you are alive. A sealed envelope with the executor that identifies hardware wallets, exchange accounts, and access protocols (but not the seed phrase itself) solves the inventory problem without exposing the seed.
Pre-mortem gifting and the five-year lookback
Can you reduce Zurich inheritance tax by gifting Bitcoin to children before death?
Yes, with structure. ZH Steuergesetz §142-150 governs Schenkungssteuer (gift tax) in Zurich. The same tiered §19 rates apply to gifts. A lifetime Freibetrag of CHF 200,000 per direct descendant exists for gifts, so each child can receive up to CHF 200,000 in Bitcoin tax-free.
The constraint sits in ZH ESchG §12. An anti-avoidance provision pulls gifts made within five years of death back into the taxable estate for Erbschaftssteuer purposes. Gifts beyond five years before death are not clawed back.

What the Pflichtteil rules mean for Bitcoin bequests
Swiss Erbrecht (inheritance law) under ZGB Art. 470-480 mandates minimum shares (Pflichtteil) for direct heirs. You cannot disinherit children or a spouse entirely under Swiss law.
The current Pflichtteil quotas after the 2023 reform:
- Descendants: 50% of their statutory share
- Surviving spouse or registered partner: 50% of their statutory share
Parents lost their Pflichtteil right in the 2023 reform.
For Bitcoin estates, this means you cannot will 100% of your Bitcoin to a charity or a sibling while children survive. The children retain their Pflichtteil claim. If the will violates it, heirs can challenge through Herabsetzungsklage within a 10-year period.
The Pflichtteil applies to the estate as a whole, not specifically to Bitcoin. But if Bitcoin is the primary asset, that is what the claim lands on.
The Zurich inheritance tax timeline
After death, the Nachlassbehörde (probate authority) opens proceedings. The estate executor (Willensvollstrecker, if named) or the heirs prepare and submit the Erbschaftsinventar within the deadline set by the cantonal authority, typically 30 days from the opening of proceedings, extendable on request.
The ZH Steuerverwaltung issues the Erbschaftssteuer assessment separately, typically 12 to 18 months after inventory submission. Payment is due within 30 days of the assessment. Interest accrues on late payment.
For a Bitcoin estate, the inventory submission step holds most of the complexity. You must apply the ESTV Kursliste valuation on the date of death correctly. You must identify self-custody wallet addresses and confirm balances. You must list exchange accounts with balance statements.
Executors unfamiliar with Bitcoin custody mechanics run aground here. The seed phrase never goes to any authority. What you submit is the CHF value and the address evidence that supports it.
