Czech Republic Crypto Tax Guide

Current Tax Treatment of Crypto (2026)

As of 2026, the Czech Republic does not have a specific law governing the taxation of cryptocurrencies. The tax treatment is derived from general provisions of the Income Tax Act (zákon o daních z příjmů) and the interpretation guidance issued by the Ministry of Finance and the tax administration (Finanční správa). Crypto assets are not treated as currency, financial assets, or commodities in the traditional sense — they are classified as "other income" (ostatní příjem) under Section 10 of the Income Tax Act for individuals, or as business income under Section 7 for systematic or professional activity.

Taxation of Crypto Gains — 15%/23% IIT

Crypto gains are subject to personal income tax (IIT) at the progressive rates of 15% (up to 36x the average wage, approximately CZK 1,935,552 for 2026) and 23% (above this threshold). The gain is calculated as the difference between the disposal price and the acquisition cost. The časový test (time test) — which exempts capital gains on shares held for more than 3 years and on real estate held for more than 5 or 10 years — does NOT clearly apply to cryptocurrency gains in 2026. This means all crypto disposals are taxable unless the taxpayer can argue the activity is not systematic and falls outside the scope of taxable income.

• Disposal triggers tax: Selling crypto for fiat, trading crypto for crypto, using crypto to purchase goods or services, and gifting crypto (unless within the exempt family circle) are all taxable events.
• Acquisition cost: The cost basis includes the purchase price plus transaction fees. For mined crypto, the cost basis is generally the fair market value at the time of receipt (taxed as business income).
• Holding period: There is no specific holding period exemption for crypto. Each disposal is a separate taxable event.

Mining — Business Income

Cryptocurrency mining is generally classified as business income (Section 7 of the Income Tax Act) if conducted systematically for profit. Miners must register as OSVČ (self-employed) and obtain a trade license (Živnostenský list) for the relevant activity. The fair market value of the mined coins at the time of receipt is taxable income, and mining expenses (hardware, electricity, rent) are deductible. Miners must also pay social insurance (29.2% of 55% of profit) and health insurance (13.5% of 55% of profit).

Exchange Reporting Obligations

Cryptocurrency exchanges and other virtual currency service providers registered in the Czech Republic (under the AML Act — zákon proti praní špinavých peněz) are required to report certain transactions to Finanční správa and the Financial Analytical Office (FAÚ). The reporting includes transactions exceeding CZK 1,000,000 and suspicious transactions. The EU's DAC8 directive (effective from 2026) will expand automatic exchange of information on crypto transactions between EU member states, further increasing transparency.

Expected Specific Crypto Law (2026-2027)

The Czech government and the Ministry of Finance have been preparing a specific law on cryptocurrency taxation, expected to be enacted in 2026 or 2027. The proposed changes may include: a clear definition of crypto assets for tax purposes, potential introduction of a holding period exemption (časový test) for crypto (e.g., 3 years), simplified reporting for small transactions, and alignment with the EU's Markets in Crypto-Assets (MiCA) regulation and DAC8. Taxpayers should monitor legislative developments closely.

FAQs

Do I need to report every crypto trade on my tax return?

Yes. Every taxable disposal must be reported on the annual tax return (daňové přiznání) as other income (Section 10) or business income (Section 7). The total gain or loss from all crypto transactions is aggregated and reported. Losses from crypto can generally be offset against other Section 10 income but not against employment or business income.

Is crypto-to-crypto trading taxable?

Yes. Trading one cryptocurrency for another (e.g., BTC for ETH) is considered a disposal of the first cryptocurrency and is a taxable event. The gain is calculated as the difference between the fair market value at the time of the trade and the acquisition cost of the first cryptocurrency.

Are there any tax-free thresholds for crypto gains?

There is no de minimis exemption for crypto gains. All gains from crypto disposals are taxable. However, if the total income (including crypto) is below the threshold for filing a tax return, no filing is required. The filing threshold for 2026 is approximately CZK 15,000 for Section 10 income (if not exceeding CZK 6,000 from each source, etc.). Professional or systematic crypto activity has no threshold.

Do I need to declare crypto held on foreign exchanges?

Yes. Czech tax residents must declare all worldwide income, including crypto gains from foreign exchanges. Failure to declare foreign-held crypto can result in penalties, and DAC8 will make cross-border crypto data sharing automatic from 2026.
