How to Do Crypto Taxes in Ireland: Records, CGT and Filing

Overview

Ireland does not have a separate magic tax universe for crypto-assets. Revenue states that there are no special tax rules for cryptocurrencies or crypto-assets; ordinary tax principles apply according to the transaction and the taxpayer's circumstances.

For an Irish-resident individual holding crypto as an investment, gains on disposal may fall within Capital Gains Tax (CGT). A person trading as a business or receiving crypto as income may face different treatment.

The practical challenge is not knowing that a sale may be taxable. It is keeping enough reliable transaction data to calculate gains in euro and report them correctly.

What May Count as a Disposal

A disposal is not limited to cashing out to a bank account. A crypto investor may create a relevant disposal when they:

• sell crypto for euro or another fiat currency;
• exchange one crypto-asset for another;
• spend crypto on goods or services;
• gift or transfer ownership of crypto.

Revenue's general CGT guidance identifies sale, gift, or exchange of an asset as disposal events. That means an exchange from one token to another can matter even though the investor continues to hold a crypto portfolio afterwards.

Transfers between wallets controlled by the same person are a separate issue: they should normally be recorded as transfers, not mistakenly treated as sales. Keeping the source and destination history prevents later confusion.

Calculating a Gain in Euro

At its simplest, a capital gain is based on proceeds less the allowable cost of the asset and relevant allowable expenses.

Chargeable gain = Disposal proceeds – allowable cost and expenses

For crypto trades, the calculation requires values in euro. When one crypto asset is exchanged for another, the transaction still needs an appropriate euro valuation at the date of disposal.

Simple example

You acquire an asset for €1,500 and later sell it for €2,100. Ignoring expenses for illustration:

€2,100 – €1,500 = €600 gain

Two figures turn that gain into a tax number. The CGT rate is 33% for most gains, and the first €1,270 of an individual's annual gains is exempt — an allowance that cannot be transferred to a spouse or civil partner.

The calculation becomes more demanding once there are repeated purchases, partial disposals, fees, exchanges, reward receipts, or activity across several exchanges.

Why Transaction Records Matter

A yearly total from an exchange is rarely enough to establish a proper CGT calculation. You need to be able to show how each relevant gain or loss was built.

Keep records of:

• acquisition and disposal dates;
• asset quantities;
• euro values at the time of transaction;
• purchase and sale documentation;
• trading and network fees where relevant;
• exchange and wallet histories;
• transfers between accounts you control;
• any crypto received through rewards, payment, or other income-related activity.

Missing data can distort both proceeds and costs. A clean calculation depends on both sides of a transaction, not merely the final sale.

Watch: Irish crypto tax, end to end

If you would rather see the process than read it, this covers the same ground — what counts as a disposal, how the gain is worked out, and what has to reach Revenue:

Capital Activity and Income Activity Are Different

Not all crypto receipts are investment acquisitions. If you receive crypto as compensation, from a business activity, or through an activity taxable as income, that receipt may need income treatment rather than being treated only as a later investment disposal.

The later sale of an asset previously received as income may still produce a separate gain or loss. This is why a useful tax record distinguishes between:

• assets bought as investments;
• assets received through income-like events;
• assets later sold or exchanged.

The same token symbol can appear in all three situations while requiring different supporting records.

Filing and Payment Timing

Revenue separates CGT payment timing from annual return filing. Revenue's guidance states that a CGT return must generally be filed on or before 31 October of the year following the disposal, including where no tax is due because of reliefs or allowable losses.

Payment runs on a different clock, and it comes first:

• disposals from 1 January to 30 November — pay by 15 December of the same year;
• disposals in December — pay by 31 January of the following year.

So a gain realised in March is paid for that December, but not returned until the following October. Missing that is easy, because the return deadline is the one everybody remembers. Crypto tax deadlines across Europe sets Ireland's dates alongside its neighbours'.

This distinction is easy to miss and decidedly unromantic, which is exactly why it belongs in your tax process.

How CryptoTaxBridge Supports Irish Reports

CryptoTaxBridge can prepare an Irish CGT support report based on imported transactions. In the app, the Irish report uses a disposal-by-disposal calculation in euro, with support for annual exemption and estimated CGT reporting data.

A support report helps organise your transaction evidence; it does not replace review of your personal classification, other assets, losses outside the imported data, relief eligibility, or filing obligation.

Organise Irish transactions

Before Preparing Your Report

Before generating any annual result, make sure you have collected:

1. every exchange account used during the period;
2. relevant wallet transfers and on-chain activity;
3. complete acquisition history for assets disposed of;
4. euro valuation data for relevant events;
5. details of income-like crypto receipts;
6. records of costs and fees.

A missing account does not merely reduce the number of lines in a report. It may remove the acquisition behind a later disposal, causing the entire result to be unreliable.

Conclusion

Irish crypto reporting is manageable when you treat records as part of the investment activity, not as a task reserved for the deadline.

For individual investors, the essential process is:

• recognise disposals, including exchanges;
• keep euro-based supporting values;
• preserve costs and fees;
• separate income-like receipts from investment disposals;
• check Revenue deadlines for payment and filing.

Accurate data first, tax calculation second. Any other order is how spreadsheets acquire mythology.
