Ireland taxes Bitcoin at 33% CGT above a €1,270 annual exemption. No holding period benefit. The 30-day bed-and-breakfast rule limits loss harvesting. Filing has split deadlines: December 15 and January 31. Full guide for Irish HODLers.
Ireland has a large, tech-savvy population and hosts the European headquarters of many major technology companies. It also has one of the highest Capital Gains Tax (CGT) rates in the developed world — 33% — applied directly to Bitcoin profits. There is no special holding-period benefit, no inflation adjustment, and no exemption for long-term HODLing.
For Irish Bitcoin holders, the tax picture is clear: profitable disposals are taxed at 33% above a modest annual exemption. Understanding the rules, the exemption mechanics, and the filing deadlines is essential for staying compliant and minimizing your bill legally.
The Revenue Commissioners (Revenue) — Ireland's tax authority — has treated cryptocurrency as a capital asset since its guidance was first published. Bitcoin disposals trigger Capital Gains Tax at the standard rate:
| Detail | Rate |
|---|---|
| Capital Gains Tax rate | 33% |
| Annual CGT exemption | €1,270 per person |
| Holding period benefit | None |
| Loss carryforward | Yes |
The €1,270 annual exemption is applied before calculating the tax owed. It applies to net annual gains (gains minus losses). Once your net gains exceed €1,270, the full amount above the threshold is taxed at 33%.
Revenue treats cryptocurrency similarly to other capital assets (shares, property). A disposal occurs when you:
Taxable:
NOT a disposal:
The crypto-to-crypto rule is critical for Irish traders: Swapping Bitcoin for Ethereum on an exchange is a full disposal of the Bitcoin position at market value, triggering CGT. Many Irish crypto traders are unaware of this and face large unexpected tax bills after active trading years.
Ireland uses specific rules for identifying which Bitcoin units you are selling. The order of priority:
The 30-day rule has important implications for loss harvesting: If you sell Bitcoin at a loss and rebuy within 30 days, the disposal is matched against the rebuy (not your original higher-cost purchase). The loss you were trying to realise is deferred until you sell the newly acquired Bitcoin.
Scenario:
Step 1: Apply FIFO (no same-day or 30-day match)
Step 2: Calculate gain
Step 3: Apply annual exemption
Step 4: Apply CGT
Ireland has a split payment deadline system for CGT that catches many taxpayers off guard:
Disposals from January 1 to November 30: Tax is due by December 15 of the same year.
Disposals from December 1 to December 31: Tax is due by January 31 of the following year.
The annual return: CGT disposals are reported in your annual Form 11 (self-assessed taxpayers) or CG1 (capital gains only) return, due by October 31 of the following year.
Why this matters: You must pay the CGT before you file your annual return. If you sell Bitcoin in June 2026 at a large gain, Revenue expects payment by December 15, 2026 — even though the formal return isn't due until October 2027. Late payment triggers interest charges (currently 8% per annum, applied from the due date).
The 33% CGT rate applies to investment-style Bitcoin holdings. Revenue may reclassify gains as income (taxed at marginal income tax rates of up to 52% including PRSI and USC) if:
Indicators of trading vs. investment: Revenue considers the "badges of trade" — frequency, purpose, financing method, nature of the asset, supplementary work done. Occasional Bitcoin purchases held for investment clearly fall under CGT. Daily high-frequency trading as a primary income activity may be reclassified as trading income.
Bitcoin mining: Mining income is typically treated as income at the time Bitcoin is mined, valued at the fair market value on the date of receipt. When the mined Bitcoin is later sold, the gain from that value to the sale price is subject to CGT.
Within-year offset: Capital losses from Bitcoin disposals (and other capital assets) offset gains in the same tax year.
Loss carryforward: Unused capital losses can be carried forward indefinitely to offset future capital gains. This is a significant benefit compared to countries like India and Brazil, which prohibit loss carryforward for crypto.
Important restriction: Capital losses can only offset capital gains — they cannot reduce income tax on salary, rental income, or business profits.
The 30-day bed-and-breakfast rule (described above) limits the ability to create artificial losses by selling and immediately rebuying.
Gifting Bitcoin: Treated as a disposal at market value for the donor → 33% CGT applies on any gain above the cost basis.
The recipient may also owe Capital Acquisitions Tax (CAT) — Ireland's gift and inheritance tax — at 33% above their applicable threshold:
Inherited Bitcoin: The deceased's estate pays CGT on the disposal (or the executor does, funded from the estate). The beneficiary receives the Bitcoin at market value on the date of inheritance — their future gains are calculated from that stepped-up value. Ireland does NOT provide a step-up in basis in the same manner as the US — the estate pays CGT, and CAT also applies.
There are no special rules distinguishing Bitcoin held on Irish exchanges from foreign exchanges. All Bitcoin — regardless of where it's custodied — is subject to Irish CGT for Irish tax residents.
Irish residents are taxed on worldwide income and gains. Revenue does not require specific foreign account reporting forms for crypto (unlike some jurisdictions), but all global Bitcoin holdings must be disclosed in your CGT return.
Revenue published specific guidance on cryptocurrency taxation in 2018 and has updated it since. Key positions:
The exemption resets each January 1. If you have gains, structure disposals to use the exemption each year rather than letting it go unused. Over 10 years, that's €12,700 of gains at 0% tax.
Sell Bitcoin at a loss before December 31 to offset gains from earlier in the year. Wait 31+ days before rebuying to avoid the bed-and-breakfast rule.
If you plan to sell a large Bitcoin position, spreading sales across multiple years uses multiple annual exemptions and may reduce the effective tax burden.
Irish pension contributions reduce your income tax base significantly (up to €115,000 of earnings, depending on age). While this doesn't directly reduce CGT, it maximises the tax efficiency of your total wealth.
Each spouse has their own €1,270 annual CGT exemption. Transfers between spouses are exempt from CGT. If one spouse has significant Bitcoin gains, consider ensuring both spouses' exemptions are used each year.
Borrowing against Bitcoin (through international platforms offering such services) does not trigger CGT — no disposal occurs. This can defer taxation while using the capital.
Missing the December 15 payment deadline: Many taxpayers focus on the October 31 return deadline and miss the earlier payment dates. Interest accrues from the actual due date.
Not reporting crypto-to-crypto trades: Revenue's position is clear: trading Bitcoin for Ethereum is a disposal. Tracking every trade is essential for crypto-active holders.
Forgetting small disposals: Even small Bitcoin spends (using Bitcoin to buy something online) are technically taxable disposals. Track everything.
Not carrying forward losses from bad years: If you had losses in 2022's bear market and didn't file a CGT return for that year, those losses are not automatically available. File returns for loss years to preserve the carryforward.
Not using the €1,270 exemption annually: Many passive HODLers never realise small gains up to the annual threshold, missing years of tax-free crystallization.

| TokenTax | Limited | Manual Irish configuration |
| Recap.io | Yes | UK/Ireland focused, good HMRC/Revenue support |
Always verify that your chosen tool implements Ireland's 30-day matching rule correctly — many tools default to US FIFO without the bed-and-breakfast rule.
Is Bitcoin legal in Ireland? Yes. There is no restriction on buying, holding, or selling Bitcoin in Ireland. Crypto asset service providers operating in Ireland must register with the Central Bank of Ireland under AML/CFT regulations.
Do I need to report Bitcoin if I didn't sell anything? If you had no disposals during the year, there is no CGT liability or CGT filing requirement. However, if you are a self-assessed taxpayer filing Form 11 for other reasons, you must disclose your Bitcoin holdings.
What if I received Bitcoin as a salary? Bitcoin received as employment income is taxed as income (PAYE) at fair market value on the date of receipt. The subsequent gain from that value to any future sale price is then subject to CGT.
Can I deduct transaction fees from my gains? Yes. Incidental costs of acquisition (exchange fees at time of purchase) and incidental costs of disposal (exchange fees at time of sale) are deductible in calculating your gain.
How does Revenue know about my Bitcoin? Cryptocurrency exchanges operating in Ireland or the EU are subject to KYC requirements and data sharing obligations. The EU's DAC8 directive (effective 2026) requires crypto asset service providers to report transaction data for EU residents to their national tax authorities. Revenue will increasingly receive this data automatically.
