Step-by-step
-
Step 1: Aggregate all transactions
Pull CSV exports from every exchange you used (Coinbase, Kraken, Binance, etc.) and add wallet addresses for on-chain activity. Coverage is everything — even a single missing trade can cascade into wrong cost basis for every subsequent disposal.
-
Step 2: Import into crypto tax software
Koinly, CoinTracker, CoinLedger, Accointing and ZenLedger all support Switzerland. Import the CSVs and link the wallet addresses. The software auto-classifies trades, transfers, swaps, staking rewards, and airdrops.
-
Step 3: Reconcile mis-tagged transactions
Most software gets 80% right but flags ambiguous events: cross-platform transfers (which look like sales), bridge events, LP token mints, and rebasing tokens. Review each warning and correct the classification.
-
Step 4: Apply the correct method and jurisdiction
In Switzerland, gains are reported as private capital gains generally tax-free; wealth tax on holdings; mining and staking taxed as income. Choose the cost-basis method (FIFO is the default in most jurisdictions) and apply consistently.
-
Step 5: Generate the tax report
Export the Switzerland-specific tax report (capital-gains schedule + income-events list). Most software outputs a PDF and the relevant Cantonal tax office format.
-
Step 6: File with Cantonal tax office
Attach the report to Cantonal tax return and submit through your normal annual filing channel. Keep all underlying CSVs and software outputs for at least 5 years in case of audit.
-
Step 7: Pay any tax owed
Plan for the cash impact — for private investors capital gains are tax-free, but wealth tax on your holdings and income tax on any staking or mining rewards still apply. These are settled through your annual cantonal tax return.
Common errors and fixes
- Missing exchange exports for a defunct platform. Use blockchain explorers to reconstruct the missing transactions. If unrecoverable, document the gap and use reasonable basis estimates with disclosure.
- Transfer between own wallets flagged as a sale. Tag both sides as a "transfer" in the tax software. Most platforms auto-detect this when both addresses are linked.
- Staking rewards not picked up. Some chains (Cosmos, Solana) need wallet auto-staking to be enabled in the tool. Manually add validator rewards if missing.
- DeFi LP positions mis-priced. LP token mints and burns are often mis-tagged as trades. Use the tool's "DeFi" view to manually mark them as deposits / withdrawals (not always taxable).
- Wash-sale or bed-and-breakfast rule. Switzerland has no crypto-specific wash-sale (bed-and-breakfast) rule; check current local guidance before harvesting losses.
FAQ
Are crypto-to-crypto trades taxable in Switzerland?
Generally no for private investors. In Switzerland, capital gains on movable private assets — including crypto-to-crypto trades (BTC→ETH, USDT→SOL, etc.) — are typically tax-free. (Professional/commercial traders are instead taxed on gains as income.) The software still computes the gain in local currency for your records.
Is staking taxable in Switzerland?
In most jurisdictions including Switzerland, staking rewards are ordinary income at the moment of receipt at fair market value.
Do I need to file if I only held and never sold?
Even if you only held, Switzerland levies an annual wealth tax, so you must declare your crypto holdings at their year-end value on your tax return. And if you received airdrops, staking, or any income event, those are taxable as income even without a disposal.
What if I lost crypto to a hack or rug pull?
Because private capital gains are tax-free in Switzerland, private capital losses — including crypto lost to theft or hacks — are generally not deductible for income tax; a proven loss can instead reduce the value of your holdings for wealth-tax purposes. Professional or commercial traders may be able to deduct losses. File a police report and keep all evidence.
