How to File Crypto Tax in Ireland

How to File Crypto Tax in Ireland (2026 Guide)

Filing crypto tax in Ireland requires reporting all taxable disposals and crypto-related income to the Revenue Commissioners (Revenue). Cryptocurrencies are treated as capital assets for Capital Gains Tax (CGT) purposes and as income when received as rewards, compensation, or services.

The Irish tax year runs from 1 January to 31 December, and all relevant transactions must be reported correctly, including exemptions, offsets, and losses.

How Crypto Is Taxed in Ireland (2026)

Capital Gains Tax (CGT)

Crypto disposals are treated as CGT events, including:

• Selling crypto for fiat
• Swapping one crypto for another
• Using crypto to purchase goods or services
• Gifting crypto (except to a spouse or civil partner)

Key CGT rules:

• Flat 33% CGT rate
• Applies to gains above the €1,270 annual exemption
• Losses can offset gains and be carried forward

Income Tax on Crypto Income

Crypto received as income is taxed under income tax rules. This includes:

• Mining rewards
• Staking rewards
• Airdrops
• Crypto earned for services or employment

Tax treatment:

• Taxed at standard income tax rates (20% or 40%)
• Subject to Universal Social Charge (USC) and PRSI, where applicable

Capital Acquisitions Tax (CAT)

Crypto received as a gift or inheritance may be subject to Capital Acquisitions Tax (CAT), depending on:

• The relationship between donor and recipient
• Lifetime exemption thresholds

Step-by-Step Filing Instructions

Step 1: Gather All Crypto Transaction Records

Collect full transaction histories from all wallets and exchanges for the tax year:

• Transaction dates
• Transaction types (sell, spend, swap, income)
• Amounts received or disposed of
• Fair market value in EUR at each transaction date
• Fees and cost basis (purchase price plus fees)

Step 2: Calculate Capital Gains and Losses

Use the following formula:

Capital Gain = Disposal Proceeds − Cost Basis

• Cost basis includes purchase price and transaction fees
• Positive result = capital gain
• Negative result = capital loss
• Apply the €1,270 CGT exemption before calculating tax

Step 3: Record Crypto Income

For crypto received as income:

• Determine the fair market value in EUR on the date received
• Include this amount in your total taxable income
• Combine with other income to determine your applicable tax bracket

Step 4: Convert All Values to Euros (EUR)

All crypto transactions must be reported in EUR:

• Use consistent and reliable exchange rate sources
• Convert values using the rate on the transaction date

Step 5: Complete the Appropriate Tax Forms

Form CG1 – Capital Gains Tax Return (PAYE Workers)

• Used if you are not normally self-assessed
• Report crypto gains above the €1,270 exemption
• Submit via MyAccount or Revenue Online Service (ROS)

Form 11 – Self-Assessment (Chargeable Persons)

You must file Form 11 if:

• You are self-employed, or
• Your non-PAYE income is €5,000 or more, or
• Your gross non-PAYE income exceeds €30,000

Form 11 includes:

• Capital gains reporting
• Crypto income reporting

Step 6: Submit and Pay by the Deadlines

Key Irish crypto tax deadlines:

• 31 October – Submit CGT returns (Form CG1)
• 31 January – Pay CGT for disposals made late in the year
• 31 October – Submit Form 11 (if applicable)

Even if your gains fall below the exemption, filing is recommended to record losses for future use.

Recordkeeping and Supporting Documentation

Irish law requires records to be kept for at least six years. Keep:

• Transaction dates and timestamps
• Wallet addresses
• Exchange transaction exports
• EUR values at transaction dates
• Proof of income events
• Cost basis and fee documentation

Good records protect you in audits or Revenue inquiries.

Common Mistakes to Avoid

1. Reporting disposals but ignoring staking or mining income
2. Failing to report gains below the €1,270 exemption
3. Excluding fees from cost basis calculations
4. Using incorrect EUR conversion rates
5. Missing CGT or Form 11 deadlines
6. Not recording losses for future offsetting
