Crypto Taxes (CH) – How To Declare
Step-by-step: how to declare crypto in Switzerland for 2026 — wealth tax, income tax (staking/mining), and what documents to keep.
- Wealth tax basics – which crypto holdings must be declared and how valuation usually works.
- Income tax rules – staking rewards, mining, and other crypto “income” explained.
- Clean documentation – the easiest way to avoid problems with your tax office.
In Switzerland, crypto is not “tax-free by default”. Most private investors must declare crypto holdings for wealth tax, and certain crypto activities can create taxable income (for example, staking rewards or mining).
This guide shows you how to declare crypto in your Swiss tax return in a practical, step-by-step way: what to include, how to value your coins, and which documents you should keep.
Note: Tax treatment can differ by canton and by your profile (private investor vs professional trader). Use this as guidance and follow your cantonal tax software.
1. Do I need to declare crypto in Switzerland?
In most cases, yes: if you hold crypto at the end of the tax year, it is typically part of your taxable wealth and should be declared (similar to bank accounts, securities, or other assets).
- Holdings at year-end → declare under wealth (assets).
- Rewards/earnings (staking, mining, airdrops depending on case) → may be taxable as income.
- Professional trading → trading profits may be taxed as income (case-by-case).

2. Wealth tax: how to declare crypto holdings
Crypto holdings are generally declared as assets for wealth tax purposes. What matters most is your position on the valuation date (usually end of the tax year).
2.1 What you should declare
- Coins and tokens held on exchanges
- Coins held in private wallets (hardware/software)
- Stablecoins and tokenised assets (if applicable)
- Crypto-related receivables (e.g., some lending positions) if recognised as your assets
2.2 Valuation (practical approach)
Many cantons accept values shown in their tax software lists (where available) or a reasonable market value at year-end. The key is to be consistent and keep evidence of the price used.
3. Income tax: staking, mining & rewards
Some crypto activities can generate taxable income. The most common examples for private individuals:
| Activity | What happens | Tax idea (simplified) |
|---|---|---|
| Staking rewards | You receive additional tokens as rewards | Often treated like taxable income at receipt/value date |
| Mining | You earn coins for validating transactions | Often treated like income (and can resemble self-employment) |
| Interest / lending rewards | You receive yield for lending/liquidity | May be income depending on structure and canton practice |
Keep detailed transaction records and value-at-receipt evidence for any “earning” events.
4. Trading gains: private investor vs professional trading
Switzerland is known for generally not taxing private capital gains on movable private assets in many cases. However, if the tax authority considers your activity professional trading, gains can be treated as taxable income.
- Occasional investing/holding is usually simpler to declare (wealth + potential income events).
- High-frequency trading, leverage, large volumes, or business-like behaviour can increase the risk of being classified as professional.
- If unsure, keep extra documentation and consider professional tax support.

- Enter year-end balance and the valuation (price) used.

6. Documents & proof: what to keep
Crypto can look complicated to tax offices if documentation is messy. Your goal is to make your declaration easy to understand.
- Year-end exchange statements (balances)
- Wallet balance evidence (screenshots/export + addresses, where reasonable)
- Transaction history exports (trades, deposits, withdrawals)
- Staking/mining reward statements and dates
- Price/valuation evidence at year-end and at reward receipt dates
Tip: Put everything into one “Crypto Taxes 2026” folder (PDF + CSV). It saves hours later.
7. Common mistakes to avoid
- Not declaring year-end holdings (wealth tax issue)
