I work in the crypto self-custody space, and the question I get most often from Swiss Bitcoin holders is not about capital gains. It is about what happens to their Bitcoin when they die.
The answer in Zurich is precise, statutory, and often surprising to people who assume inheritance tax mirrors wealth tax. Spouses owe nothing. Children owe 2 to 6 percent depending on the amount. And the Bitcoin valuation method is locked to a single government source. None of this is discretionary.
This post covers the Zurich-specific rules only. Federal rules and other cantons differ. Read to the end if you have a CHF multi-million Bitcoin position, because 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
This is the starting point and it matters. DBG Art. 44 explicitly excludes inheritances from federal income tax in Switzerland. There is no federal Erbschaftssteuer at all. What you are navigating is purely cantonal.
Each of Switzerland's 26 cantons sets its own rates, exemptions, and brackets. Zurich is not the most generous (Zug exempts direct descendants entirely) but it is far from the most punitive. Knowing the federal picture is zero lets you focus entirely on the Zurich statute.

Zurich inheritance tax rates by relationship
ZH ESchG structures rates by the heir's relationship to the deceased. The closer the relationship, the lower or zero the 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. The registered partner exemption under §17a follows the same logic for Swiss-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% |
These rates apply to each heir's individual share, not to the total estate. A CHF 2M estate split between two children creates two separate 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 highest bracket. Swiss Erbrecht also limits such bequests by 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, published by the Federal Tax Administration, using the Bitcoin reference rate on the date of death.
If the deceased held 2 BTC and 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. The ESTV publishes these rates regularly and they are accessible at estv.admin.ch.
For Bitcoin held at a Swiss custodian (Sygnum, Crypto Finance, or similar), the custodian will provide a balance statement on the date of death. The cantonal authority will cross-reference it against the ESTV rate. For self-custody holdings, the estate executor is responsible for identifying wallet addresses and computing the CHF value using the ESTV rate.
One practical problem: hardware wallets with lost or undisclosed seed phrases make the estate inventory impossible to complete accurately. The Bitcoin is technically part of the estate but is unrecoverable. For practical steps on ensuring heir access to self-custody Bitcoin, the estate planning framework in the Bitcoin Taxes Switzerland chapter covers the relevant disclosure mechanics.
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. The spouse exemption dominates at this estate size.
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 because 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.
At this estate size, the 6% bracket dominates. The combined Erbschaftssteuer is 5.46% of the total estate value, driven by the high proportion of CHF in the top bracket.
These three scenarios illustrate the critical threshold: once any heir's share exceeds CHF 1,000,000, the 6% rate applies to everything above that line. A CHF 10M Bitcoin estate with two children produces a materially different tax outcome than the same estate with four children (each inheriting CHF 2.5M, with a smaller proportion at 6%).
Disclosure obligations under AMLO-FINMA Art. 51
Digital asset inheritance has a disclosure dimension that does not apply to most other asset classes. 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 are legally 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 must reconstruct the wallet inventory from the deceased's records.
This is the operational argument for structured estate planning while the Bitcoin holder is 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
One common question: can you reduce Zurich inheritance tax by gifting Bitcoin to children before death?
Technically yes. 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, which means each child can receive up to CHF 200,000 in Bitcoin tax-free via gift.
The structural constraint: ZH ESchG §12 includes an anti-avoidance provision pulling 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 (post-2023 reform):
- Descendants: 50% of their statutory share
- Surviving spouse or registered partner: 50% of their statutory share
Parents no longer have a Pflichtteil right (removed in the 2023 reform).
For Bitcoin estates, this means a testator cannot will 100% of their Bitcoin to a charity or a sibling while children survive. The children retain their Pflichtteil claim. If the will violates this, heirs can challenge it (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, it is what the claim lands on.
The Zurich inheritance tax timeline
After death, the Zurich process runs as follows. 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 is where most complexity sits. The ESTV Kursliste valuation on the date of death must be correctly applied. Self-custody wallet addresses must be identified and balances confirmed. Exchange accounts must be listed with balance statements.
Executors who are unfamiliar with Bitcoin custody mechanics frequently encounter problems at this stage. The seed phrase cannot be submitted to any authority. What is submitted is the CHF value and the address evidence that supports it.
