Iceland Crypto Tax Guide 2026
Cryptocurrency is treated as a capital asset in Iceland. Gains are subject to 22% capital gains tax. Mining and trading as a business may be treated as ordinary income.
Classification of Crypto Assets
RSK treats cryptocurrencies as capital assets for individuals. The disposal of crypto (selling for fiat, exchanging for other crypto, or using for purchases) triggers a taxable event.
Tax Rate
- 22% CGT — on gains from disposal of crypto held as an investment
- IIT rates (36.94–46.28%) — if mining, staking, or trading constitutes a business activity or employment
Cost Basis and Gains Calculation
Gains are calculated as proceeds minus cost basis. Iceland uses the FIFO (First-In, First-Out) method by default. Costs include purchase price plus transaction fees.
Mining and Staking
- Mining: If conducted as a regular business, mining income is taxable as business income at IIT rates. Expenses (equipment, electricity) are deductible.
- Staking rewards: Likely treated as investment income at 22% at the time of receipt. The fair market value at receipt becomes the cost basis for future disposal.
DeFi and Lending
Interest or returns from crypto lending, DeFi yield farming, and liquidity provision are taxable as investment income at 22%. The characterisation depends on the specific arrangement.
Losses
Crypto losses can offset crypto gains and other capital gains in the same year. Unused losses carry forward for 3 years.
Reporting
All crypto transactions must be reported on your annual tax return. RSK requires detailed records of each transaction, including dates, amounts, counterparties, and fair market values. Several Icelandic exchanges report transaction data to RSK automatically.
Energy-Intensive Mining
Iceland's abundant geothermal and hydroelectric power has attracted crypto miners. Large-scale mining operations are subject to business registration, CIT at 20%, and VAT considerations on imported equipment.
