Complete guide: crypto taxation in Ireland (2026)

Taxation of cryptocurrencies in Ireland

In Ireland, capital gains on cryptocurrencies are subject to tax. The calculation method used is FIFO with a rate of 33%. Understanding these rules is essential to stay compliant with tax legislation.

The FIFO method explained in detail

The First-In-First-Out (FIFO) method considers that the first assets purchased are the first sold. The gain is calculated on the difference between the sale price and the purchase price of the oldest lot.

Taxable events

• ●Sale of crypto for fiat currency (EUR, USD...)
• ●Payment for goods or services with cryptocurrencies
• ●Crypto-to-crypto exchanges: taxable in most countries (Germany, Spain, Italy...), but NOT in France
• ●Receiving staking rewards: taxable as income at the time of receipt
• ●Airdrops and free tokens: generally taxable at the value upon receipt
• ●Mining income: taxable as business income or miscellaneous income
• ●Crypto-to-crypto exchange (in some countries only)
• ●Transfer between your own wallets
• ●Holding (HODL): holding without selling does not create any tax obligation (except in the Netherlands, Box 3)

Tax declaration procedure in Ireland

You must declare your crypto capital gains on the following forms: Form 11, CG1. We recommend keeping the complete history of your transactions as proof.

Exemption thresholds and allowances

Some EU countries provide exemption thresholds below which crypto capital gains are not taxable. In Ireland, the threshold is 1 270€. If your annual capital gains are below this amount, you owe no tax (though you may still be required to file a declaration). Other countries offer holding period exemptions: in Germany, crypto held for more than 12 months is tax-free; in Czechia, 3 years; in Slovenia, the exemption is progressive up to 15 years.

Deadlines and tax calendar

Each EU country has its own tax filing deadlines. In Ireland, the income tax return (including crypto capital gains) must generally be filed between April and June of the following year. We strongly recommend preparing your crypto tax return in advance with Taxes Crypto rather than waiting until the last moment.

Penalties for non-declaration

Failing to declare your crypto capital gains can lead to significant penalties: tax surcharges (10% to 40%), late-payment interest, and in serious cases, criminal prosecution for tax fraud. With DAC8 (2026), Binance automatically transmits your data to tax authorities, making detection of non-filers virtually automatic.

Tax treatment of crypto-to-crypto exchanges

The tax treatment of crypto-to-crypto exchanges (e.g., BTC to ETH) varies significantly from country to country. In France, they are not taxable — only conversions to fiat currencies trigger taxation. In Germany, Spain, Italy and the majority of other countries, each crypto-to-crypto exchange is a taxable event. Taxes Crypto automatically applies your country's rules.

NFTs, DeFi and derivatives

NFTs are treated for tax purposes like other crypto assets: buying and selling them generates a taxable capital gain. DeFi transactions (decentralised swaps, liquidity provision, yield farming) are also taxable. Each swap on a DEX is fiscally equivalent to a crypto-to-crypto exchange. Crypto derivatives (futures, options) follow the financial derivatives tax regime of each country.

Obligation to declare foreign crypto accounts

In many EU countries, you must declare accounts held on foreign platforms. In France, the 3916-bis form is mandatory, with a fine of €750 per account (€1,500 if the value exceeds €50,000) for non-compliance. In Spain, the Modelo 720/721 requires declaration of foreign assets exceeding €50,000.

Practical calculation examples in Ireland

Let's look at a concrete example to illustrate crypto capital gains calculation in Ireland using the FIFO method. Imagine an investor who buys 1 BTC at €20,000 in January, then 0.5 BTC at €25,000 in March. They later sell 0.8 BTC at €35,000 in September. Using the FIFO method, the acquisition cost is calculated according to the specific rules of this approach. The taxable gain is the difference between the sale price (€28,000) and the weighted acquisition cost of the 0.8 BTC sold. In Ireland, this gain is subject to a rate of 33%. It is essential to maintain a detailed record of every transaction, including the date, crypto amount, EUR exchange rate at the time of the transaction, and any fees. Taxes Crypto fully automates this calculation for you.

Tax calendar and key dates in Ireland

Each country imposes specific tax deadlines for declaring crypto assets. In Ireland, the income declaration period generally opens in spring for the previous tax year. It is crucial to meet these deadlines: a delay can result in penalties ranging from 10% to 40% of the amount owed, depending on the circumstances. With the implementation of the DAC8 directive in 2026, exchange platforms will be required to automatically report their users' transactions to tax authorities. This means tax administrations will have detailed information about your crypto activities. Prepare your declaration as early as possible using Taxes Crypto to generate a complete tax report before the deadlines.

Specific tips for Ireland

Crypto taxation in Ireland has certain specificities that are important to know. The FIFO calculation method imposes a precise logic for determining the order of disposals. Investors should be particularly vigilant about the following: crypto-to-crypto exchanges may be taxable depending on the jurisdiction, airdrops and hard forks have specific tax treatment, and staking or mining income is generally considered taxable income upon receipt. In case of a change of tax residence, the rules of your new country apply for future transactions, but unrealised gains may be subject to an exit tax in certain cases. Consult a tax professional if your situation is complex.
