TL;DR
- Capital gains: 0% (federal exemption for private investors)
- Wealth tax range: 0.5‰–3‰

Canton Zurich — Switzerland's largest canton by population — applies the same federal Bitcoin tax framework as the rest of the country: capital gains on private holdings are tax-free under StG-ZH §16 paragraph 3, but Bitcoin is subject to annual cantonal wealth tax (Vermögenssteuer, StG-ZH §38) on its 31 December valuation. Zurich's Steueramt publishes its own Bitcoin guidance under the cantonal Steuerbuch (ZStB 16.5), confirming that Bitcoin must be declared on the Wertschriftenverzeichnis at the ESTV-published year-end value, regardless of where it is held. Zurich's wealth tax tariff (einfache Staatssteuer, StG-ZH §47) is progressive from 0.5‰ to 3‰ across six taxed brackets above the zero band; the effective burden for a Stadt Zürich resident equals the einfache Staatssteuer multiplied by the Steuerfuss (Staat 98% + Gemeinde 119% in 2024 and 2025 = 217%), so the effective range for tax year 2025 works out to roughly 1.085‰ to 6.51‰. For tax year 2026 the Staatssteuerfuss falls to 95% (95% + 119% = 214%, roughly 1.07‰ to 6.42‰).

| Wealth tax brackets | Vermögenssteuer (StG-ZH §47) — einfache Staatssteuer progressive, tax year 2025: 0‰ up to CHF 80,000 (single) / CHF 159,000 (Verheiratetentarif); then 0.5‰ → 1‰ → 1.5‰ → 2‰ → 2.5‰ → 3‰ at progressive thresholds (top 3‰ above CHF 3,262,000 single / CHF 3,342,000 Verheiratetentarif). Effective burden = einfache Staatssteuer × Steuerfuss (Staat 98% + Gemeinde 119% Stadt Zürich, 2024 and 2025 = 217%) → roughly 1.085‰ to 6.51‰ effective for a Stadt Zürich resident. Tax year 2026: zero band CHF 81,000 / CHF 161,000, top 3‰ above CHF 3,304,000 / CHF 3,385,000 (Verordnung über den Ausgleich der kalten Progression of 30 June 2025, in force 1 January 2026), Steuerfuss 95% + 119% = 214% (1.07‰ to 6.42‰). Church tax (Kirchensteuer) adds 10% of the einfache Staatssteuer in Stadt Zürich for Reformed and Roman Catholic members (14% Christkatholisch); non-members pay none. |

Worked example
Suppose a Stadt Zürich resident (single, unaffiliated with a recognized church) held 1.5 BTC on 31 December 2025 with no other taxable assets. The ESTV year-end value for 2025 was CHF 69,571.99 per BTC, so the taxable holding equals 1.5 × CHF 69,571.99 = CHF 104,357.99. Subtract the zero band for a single filer (CHF 80,000 for tax year 2025 under StG-ZH §47) — taxable wealth in the 0.5‰ band becomes CHF 24,357.99. Apply the einfache Staatssteuer rate of 0.5‰: 24,357.99 × 0.0005 = CHF 12.18 einfache Staatssteuer. Multiply by the combined Steuerfuss (Staat 98% + Stadt Zürich 119% = 217%): CHF 12.18 × 2.17 ≈ CHF 26 per year total Vermögenssteuer on this Bitcoin position — the same figure the estimator below returns for 1.5 BTC. For larger holdings the marginal rate climbs progressively, reaching the 3‰ top bracket only above CHF 3,262,000 single (CHF 3,342,000 Verheiratetentarif) for tax year 2025. For tax year 2026 the zero band is CHF 81,000 single / CHF 161,000 Verheiratetentarif and the 3‰ band starts above CHF 3,304,000 / CHF 3,385,000 (Verordnung über den Ausgleich der kalten Progression of 30 June 2025, in force 1 January 2026).

Common mistakes
Three Zurich-specific mistakes I see annually: (1) Filers report Bitcoin at the exchange purchase price rather than ESTV's 31 December valuation — Zurich's Steueramt corrects this in the assessment. Always use the ESTV Kursliste value. (2) Transfers between your own wallets are reported as taxable disposals — they are not. The wealth-tax basis is your total Bitcoin balance on 31 December, regardless of how many wallet addresses hold it. (3) Mining and staking rewards are reported under wealth tax instead of income tax — mining rewards are income from self-employment (ZStB 16.5) and staking rewards are investment income (ESTV practice); both are declared on the income tax return at market value at receipt.
Special notes
Zurich publishes a one-page Praxishinweis (ZStB 16.5, 20 December 2017, 'Steuerliche Behandlung von Kryptowährungen (Bitcoin etc.)') on Bitcoin and comparable coins. Zurich's ZHprivateTax portal is used to file the return online. The Staatssteuerfuss falls from 98% (2024 and 2025) to 95% for 2026 and 2027, marginally lowering the effective wealth-tax burden from tax year 2026. For large holdings, consider professional advice.
Frequently asked questions
What wealth tax rate does Canton Zurich apply to Bitcoin holdings?
Zurich's wealth tax tariff (Vermögenssteuer, einfache Staatssteuer per StG-ZH §47) is progressive from 0.5‰ to 3‰ across six taxed brackets above the zero band (CHF 80,000 single / CHF 159,000 Verheiratetentarif for tax year 2025; CHF 81,000 / CHF 161,000 from 2026 under the Verordnung über den Ausgleich der kalten Progression of 30 June 2025, in force 1 January 2026). The effective rate equals the einfache Staatssteuer multiplied by the combined Steuerfuss — for Stadt Zürich (Staat 98% + Gemeinde 119% in 2024 and 2025) that is 217%, giving an effective range of roughly 1.085‰ to 6.51‰ (2026: 95% + 119% = 214%, 1.07‰ to 6.42‰). Bitcoin is taxed at its ESTV year-end value — CHF 69,571.99 per BTC for tax year 2025 (down from CHF 85,926.49 for 2024).
Where do I declare Bitcoin on the Zurich tax return?
Bitcoin holdings go on the Wertschriften- und Guthabenverzeichnis (securities and assets schedule), declared as «übrige Guthaben» with the cryptocurrency name (per ZStB 16.5). Use the ESTV ICTax / Kursliste year-end value, not your purchase price. Mining income is self-employment income (ZStB 16.5) and staking rewards are investment income (ESTV practice); both go on the income side, not the wealth line.
When is the Zurich Bitcoin tax filing deadline?
31 March of the year following the tax year (so 31 March 2026 for the 2025 tax year). Extensions are requested from your Gemeindesteueramt before the deadline — Stadt Zürich normally grants until 30 September and, on a further request, until 30 November (ZStB 132.1); deadlines vary by Gemeinde. In Stadt Zürich the request goes through the «Fristerstreckung online» form or the «Steuern verwalten» account, not through the ZHprivateTax return itself. ZStB 132.3 recorded a one-off blanket extension to 30 April 2025 for 2024 returns; no equivalent is published for 2025 returns. Late filings without an approved extension trigger a reminder with a 10-day deadline; if you still do not file, the Steueramt assesses you at its discretion and can impose an Ordnungsbusse (StG-ZH §234). No fee is charged for the reminder.
Does Zurich publish Bitcoin-specific tax guidance?
Yes. The cantonal Steuerbuch entry ZStB 16.5 ('Steuerliche Behandlung von Kryptowährungen (Bitcoin etc.)') documents Zurich's treatment of Bitcoin and comparable cryptocurrencies. It confirms the ESTV year-end Steuerkurs as the wealth-tax basis (StG-ZH §38), classifies private capital gains as tax-free under StG-ZH §16 paragraph 3, and clarifies that mining for compensation generates taxable income from self-employment.
How does Canton Zurich treat Bitcoin self-custody for tax purposes?
Zurich treats self-custody Bitcoin identically to exchange-held Bitcoin for tax purposes: declared at ESTV year-end value on the Wertschriftenverzeichnis, with a wallet printout at year end as proof (ZStB 16.5). Transfers between your own wallets are not taxable events. Coins you can no longer access are not part of your wealth on 31 December; keep evidence of the loss in case the Steueramt asks why a previously declared balance disappeared.
Is Bitcoin capital gains tax-free in Zurich?
Yes — for private investors. Capital gains from selling Bitcoin are exempt from federal AND cantonal income tax in Zurich, consistent with the federal framework. The exception is if you classify as a professional trader under the ESTV Kreisschreiben 36 criteria for professional securities trading (applied by analogy), in which case gains become ordinary income.
Does CARF reporting apply to Zurich residents in 2026?
Not in 2026. Switzerland will apply the crypto-AIA (CARF, Crypto-Asset Reporting Framework) at the earliest from 1 January 2027; Parliament has not yet approved the list of partner states (SIF, 18 May 2026). If applied from 2027, Swiss crypto service providers collect 2027 data and the ESTV exchanges it with partner states from 2028 at the earliest. Tax liability does not change — only visibility.
Can I deduct Bitcoin losses in Zurich?
Capital losses on private Bitcoin holdings cannot be deducted (since gains aren't taxed either — symmetric treatment). Coins that are gone for good (lost seed phrase, exchange bankruptcy with no recovery) are simply not part of your wealth on 31 December, so they drop out of the wealth-tax basis; keep evidence of the loss. Mining costs are deductible business expenses when mining is self-employment income.
