How to Calculate Crypto Capital Gains Tax in Ireland
Revenue Commissioners impose a 33% Capital Gains Tax on cryptocurrency disposals, one of the highest rates in the EU. Individuals benefit from an annual exemption of €1,270. Losses can be carried forward indefinitely but cannot offset income tax. Ireland's "Bed and Breakfast" rule prevents repurchasing the same asset within four weeks to claim a loss. Gifting crypto to anyone other than a spouse is a disposal. This calculator estimates your CGT using Revenue's flat rate for the 2025 tax year.
The Ireland Crypto Tax Estimator uses the Revenue Commissioners CGT model for 2025. Gains are calculated as: Gain = (Selling Price − Purchase Price) × Quantity. Individuals can deduct the annual exemption of €1,270 from their total gains for the tax year. Any gain above this threshold is taxed at a flat 33%. The calculation is: Taxable Gain = max(0, Total Gains − €1,270), and Tax = Taxable Gain × 33%. Losses can be carried forward indefinitely to offset future gains but cannot offset other income. The "Bed and Breakfast" rule disallows a loss if you repurchase the same crypto within four weeks of the disposal. Gifting crypto to anyone other than your spouse or civil partner is treated as a disposal at market value. The calculator does not model specific spouse transfer rules or the small disposal exemption.
Track your gains throughout the year using the Profit/Loss Calculator so you are prepared for end-of-year tax filing. To work out your cost basis across multiple buys, use the DCA calculator.

Filing Guide — Office of the Revenue Commissioners
Irish taxpayers must file Form CG1 for chargeable gains if they are not already in the self-assessment system. If you file a Form 11 tax return, include your gains there. The deadline is mid-November for disposals between January and November, and mid-January for December disposals. Payments can be made online through Revenue's ROS system. Keep all transaction records with euro valuations for at least six years.
Common Mistakes to Avoid
A common Irish mistake is not realizing the Bed and Breakfast rule applies to crypto — selling at a loss and buying back within four weeks defers the loss. Another error is treating gifts to friends or family as non-taxable; they are disposals at market value unless the recipient is your spouse or civil partner. Many taxpayers also forget to use their €1,270 annual exemption or fail to carry forward losses, which can be used indefinitely against future gains.

Ireland Crypto Tax Estimator — FAQ
What is the crypto tax rate in Ireland?
Ireland applies a flat 33% Capital Gains Tax on cryptocurrency disposals. This is one of the highest CGT rates in the European Union. Individuals can deduct an annual exemption of €1,270 from their total gains.
Can I offset crypto losses against my salary in Ireland?
No. Capital losses can only offset capital gains. They cannot be used to reduce your income tax or PRSI. However, unused losses carry forward indefinitely to offset future capital gains.
What is the Bed and Breakfast rule?
The Bed and Breakfast rule prevents you from claiming a capital loss if you repurchase the same cryptocurrency within four weeks of selling it. The loss is deferred and added to the cost basis of the new purchase instead.
Do I pay tax when gifting crypto in Ireland?
Yes. Gifting cryptocurrency to anyone other than your spouse or civil partner is treated as a disposal at market value. You must calculate the gain and pay 33% CGT if the gain exceeds your annual exemption.
Are crypto-to-crypto swaps taxable in Ireland?
Yes. Swapping one cryptocurrency for another is a taxable disposal. You must calculate the euro market value of the crypto received and report any gain or loss relative to your original cost basis.
When is the CGT filing deadline in Ireland?
For disposals between January and November, the deadline is mid-November of the same year. For December disposals, the deadline is mid-January of the following year. Late filing incurs interest and penalties.
