Crypto tax is one of the most searched topics among Irish crypto holders — and one of the most misunderstood. Many beginners assume that because crypto feels different from traditional investments, it might be treated differently by Revenue. It is not. Revenue has clear rules on how crypto is taxed and from 2026, exchanges are legally required to share your transaction data with them automatically.

This guide gives you a plain English overview of Irish crypto tax rules — what is taxable, what is not, how much you owe, when to pay, and how to report it. This is a beginner overview, not professional tax advice. For complex situations, always consult a qualified Irish tax adviser.

Revenue can see your crypto transactions. From January 2026, DAC8 and CARF regulations require all EU exchanges to automatically report user transaction data to Revenue. If you use Coinbase, Kraken, Binance, or any other EU-registered exchange, assume Revenue already has your data. Blockchain transactions are also publicly visible and Revenue uses data analysis tools. Treat your crypto activity as fully visible from day one.

How Revenue Treats Crypto

Revenue does not treat cryptocurrency as a currency. It treats it as a capital asset — similar to shares, property, or any other investment asset. This single fact determines almost everything about how crypto is taxed in Ireland.

Because crypto is an asset rather than a currency, the tax rules that apply are those for capital gains — specifically Capital Gains Tax (CGT) at 33%. When you make a profit from an asset, you pay CGT on that profit. When you sell crypto for more than you paid, that profit is taxable.

This also means that the rules are surprisingly straightforward for most casual investors. If you bought Bitcoin, held it, and eventually sold it for a profit — you calculate the gain and pay 33% on anything above €1,270.

What Is and Is Not a Taxable Event

Understanding what triggers a tax liability is the most important thing to get right. Many beginners are surprised to discover that swapping between cryptocurrencies is taxable, not just selling to euros.

✓ Taxable events (CGT applies)

  • Selling crypto for euros or any other fiat currency
  • Swapping one cryptocurrency for another (e.g. BTC → ETH)
  • Spending crypto on goods or services
  • Receiving crypto as payment for work or services
  • Gifting crypto to someone other than a spouse or civil partner
  • Receiving staking rewards or mining income (taxed as income on receipt, then CGT on later disposal)

✗ Not taxable events

  • Buying crypto with euros
  • Simply holding crypto long term
  • Transferring crypto between wallets you own
  • Transferring crypto to a spouse or civil partner
  • Buying crypto with a credit or debit card

The crypto-to-crypto trap: This catches many beginners off guard. Swapping Bitcoin for Ethereum is treated as two transactions by Revenue — you disposed of Bitcoin (triggering CGT on any gain) and acquired Ethereum. Every swap, bridge, or DeFi interaction that exchanges one token for another is a disposal. Keep records of every single swap, not just euro cash-outs.

Capital Gains Tax — The Basics

Capital Gains Tax in Ireland is charged at a flat rate of 33% on gains above the annual exemption. There is no progressive rate — the same 33% applies whether your gain is €2,000 or €200,000.

The €1,270 annual exemption

Every individual in Ireland has an annual CGT exemption of €1,270. The first €1,270 of net gains in any tax year is completely exempt from CGT. This exemption cannot be carried forward — if you do not use it in a given year, it is lost. It also cannot be transferred to a spouse (though spouses each have their own €1,270 exemption).

How to calculate your gain

Your taxable gain is simply: Sale proceeds minus your original cost. You can also deduct allowable expenses such as trading fees paid when buying and selling. The resulting figure — after the €1,270 exemption — is your taxable gain, and you pay 33% on that amount.

Losses reduce your tax bill

If you sold any crypto at a loss in the same year, those losses can be offset against your gains before calculating the tax owed. Only the net gain is taxed. Unused losses can also be carried forward to future years indefinitely.

Worked Example

📊 Example CGT Calculation — Irish Crypto Investor 2026

Bought 0.1 BTC in January 2024 €4,000
Sold 0.1 BTC in March 2026 €8,500
Trading fees (allowable deduction) − €60
Gross gain €4,440
Annual CGT exemption − €1,270
Taxable gain €3,170
CGT owed (33% of €3,170) €1,046

In this example, the investor made a profit of €4,440 after fees, used the €1,270 exemption, and owes €1,046 in CGT to Revenue. This must be paid by 15 December 2026 (as the gain was made before December) and declared on the annual tax return by 31 October 2027.

When Income Tax Applies Instead

Not all crypto income is subject to CGT. Some types of crypto activity are treated as income rather than capital gains, and are taxed at your normal income tax rate — either 20% or 40% depending on your total earnings.

Frequent trading: If Revenue determines that your crypto activity constitutes a trade rather than an investment — based on frequency, volume, and commercial intent — all profits may be taxed as income rather than CGT. This is known as the Badges of Trade. If you trade crypto very frequently, seek specific advice from an Irish tax adviser about how your activity may be classified.

Using Losses to Reduce Your Tax Bill

Crypto losses are not just bad news — they are a legitimate tax tool. Revenue allows you to use capital losses to reduce your CGT liability in several ways:

Practical tip: If you are approaching year end and have some coins sitting at a loss, selling them before 31 December locks in the loss for that tax year and reduces your overall CGT bill. This is a common and legitimate tax planning strategy. You can then buy the same coins back immediately if you wish — there is no wash sale rule in Ireland like there is in some other jurisdictions.

Key Dates and Deadlines

CGT Payment — Period 1

15 December

CGT due on gains made between 1 January and 30 November of the same year.

CGT Payment — Period 2

31 January

CGT due on gains made during December of the previous year.

Tax Return Declaration

31 October

Annual tax return declaring all gains and losses must be filed by 31 October of the following year via ROS or MyAccount.

Record Keeping

6 Years

Irish tax law requires you to keep transaction records for at least six years. Keep dates, euro values, exchange statements, and wallet records.

Late payment penalties apply. Revenue charges interest on late CGT payments. The payment deadlines are separate from the filing deadline — you must pay by December 15th even if you have not yet filed your return. Do not wait until October to calculate what you owe.

How to Report to Revenue

How you report depends on whether you are a PAYE worker or self-employed:

PAYE workers

File a Form CG1 through Revenue's MyAccount portal at myaccount.revenue.ie. This is a straightforward form that asks for details of your disposals, the proceeds, the original cost, and any losses. If your only income is PAYE employment and your only additional tax obligation is CGT from crypto, this is all you need.

Self-employed individuals

Report crypto gains on your Form 11 through Revenue Online Services (ROS). Crypto CGT is included in the capital gains section of the return alongside any other asset disposals.
