Selling a property, shares, business assets or another chargeable asset can create a tax liability on the profit made from the disposal. Understanding capital gains tax ireland rules before completing a transaction can help you estimate the liability, identify available reliefs and meet Revenue payment and filing requirements. The tax is generally calculated on the gain rather than the full amount received from selling an asset.
The calculation can involve acquisition costs, allowable expenses, enhancement expenditure, capital losses and specific reliefs. Finsoul Ireland provides Tax Services Ireland to support businesses and individuals with tax calculations, compliance requirements, returns and relevant tax planning.
What Is Capital Gains Tax in Ireland?
If you are searching for what is capital gains tax ireland, it is a tax on the profit, or gain, made when certain assets are disposed of. A disposal can include a sale, gift, or transfer of an asset. In some circumstances, Revenue requires the market value of an asset to be considered instead of the actual amount received. CGT can apply to assets including:
- Property and land
- Shares and securities
- Business assets
- Certain interests in companies
- Other chargeable assets
Revenue confirms that CGT is calculated on the chargeable gain rather than the total sale proceeds. The basic calculation takes account of the amount received, the acquisition cost and allowable expenses. Irish residents can also have CGT obligations relating to certain assets located outside Ireland, depending on their circumstances and the relevant tax rules. Non-residents may have Irish CGT obligations on specified Irish assets, including Irish land and buildings.
When Does Capital Gains Tax Apply?
CGT generally becomes relevant when a chargeable asset is disposed of at a gain. Simply owning an asset that has increased in value does not normally create a CGT liability. The disposal is the event that brings the gain into the tax calculation. The position can become more complicated when an asset is gifted, transferred between connected parties or sold for less than its market value. Revenue states that market value may need to be used in certain circumstances.
This is particularly important for property, business transfers and transactions involving family members or connected companies. Reviewing the tax position before a transaction can help identify issues that might otherwise arise after completion.
How to Calculate Capital Gains Tax in Ireland
The starting point is to establish the disposal proceeds and deduct the original acquisition cost together with qualifying expenses. Enhancement expenditure that adds value to the asset may also be relevant. A simplified calculation is:
Disposal proceeds − acquisition cost − allowable expenses = chargeable gain
After calculating the chargeable gain, relevant capital losses and the individual’s annual personal exemption are considered. The remaining taxable gain is then subject to the applicable CGT rate. Revenue confirms that allowable expenses can include expenditure that adds value to an asset and certain costs incurred when acquiring or disposing of it, including qualifying solicitor or auctioneer fees. Individuals have a personal exemption of €1,270 each year.
| Calculation stage | What it means | Example |
| Disposal proceeds | Amount received for the asset | €150,000 |
| Less acquisition cost | Original cost of purchasing the asset | €100,000 |
| Less allowable expenses | Qualifying acquisition, disposal or enhancement costs | €5,000 |
| Chargeable gain | Gain after allowable costs | €45,000 |
| Less personal exemption | Annual individual exemption | €1,270 |
| Taxable gain | Amount remaining after exemption | €43,730 |
| CGT at 33% | Illustrative tax on the taxable gain | €14,430.90 |
A capital gains tax calculator ireland search can provide an initial estimate, but online calculators may not account for specific relief conditions, previous losses, ownership history, market-value rules or more complicated transactions. Significant disposals should therefore be reviewed against the actual facts and applicable revenue requirements.
Capital Gains Tax Calculation Example
Suppose an individual sells an investment asset for €150,000. The original purchase cost is €100,000 and qualifying acquisition and disposal expenses total €5,000. The initial gain is €45,000. After the €1,270 annual personal exemption, the taxable gain is €43,730. Applying the standard 33% rate produces an illustrative CGT liability of €14,430.90. This example assumes that no capital losses or additional reliefs apply. The actual liability can differ depending on the asset, disposal date, taxpayer’s circumstances and reliefs available.
Capital Gains Tax Rates and Annual Exemption
The standard capital gains tax rate ireland taxpayers should generally expect for most gains is 33%. Revenue also provides different rates for specific types of gains. For example, certain foreign life policies and foreign investment products can be subject to a 40% rate, while specified venture capital fund gains can have different rates depending on the taxpayer. Individuals have a €1,270 annual personal exemption. This is applied when calculating the taxable gain and is not a general exemption from tax on the first €1,270 of sale proceeds.
The capital gains tax allowance ireland taxpayers refer to is therefore the annual personal exemption available to an individual. It should not be confused with the total amount that can be received from an asset sale without tax. Companies, trusts and other taxpayers can have different tax treatment, so the rules applying to an individual should not automatically be applied to another type of taxpayer.
Allowable Costs When Calculating CGT
Allowable costs can materially reduce the gain subject to tax. Taxpayers should keep records supporting the expenditure included in their calculation. Potentially relevant costs may include:
- Original acquisition costs
- Certain solicitor’s fees
- Auctioneer or estate agent fees
- Professional costs connected with disposal
- Qualifying expenditure that enhances the value of an asset
Revenue specifically identifies acquisition and disposal costs and qualifying enhancement expenditure as relevant to calculating the chargeable gain.
Invoices, contracts, receipts and other supporting records should therefore be retained. Estimated figures should not be used where appropriate documentation can reasonably be obtained. For businesses, accurate accounting records can make it easier to trace transactions and supporting expenditure.
Capital Losses and CGT
Capital losses can reduce taxable gains. Where an individual has both gains and allowable losses during the same tax year, the losses can generally be used against gains in accordance with Revenue rules. Unused allowable losses may also be relevant in later years, subject to the applicable requirements. This means taxpayers should review their complete investment and disposal position rather than looking at a profitable transaction on its own.
For example, a gain on the sale of shares may be reduced by an allowable loss arising from another investment. The calculation should therefore take account of the wider tax-year position. Records of previous losses should also be retained so that available losses can be considered when a later disposal takes place.
Capital Gains Tax Filing and Payment Deadlines
The date of disposal determines when CGT must be paid and when the return must be filed. For disposals made between 1 January and 30 November, CGT is generally due by 15 December of the same year. For disposals made between 1 December and 31 December, CGT is generally due by 31 January of the following year.
The CGT return must generally be filed by 31 October of the year following the disposal. Revenue confirms that this filing requirement applies even where no tax is due because of reliefs or allowable losses. For example, an asset disposed of in October 2026 would generally have a payment deadline of 15 December 2026 and a return deadline of 31 October 2027. An asset disposed of in December 2026 would generally have a payment deadline of 31 January 2027, while the return would generally be due by 31 October 2027. Late payment can result in interest, and a late return can result in a penalty.
How to File Capital Gains Tax in Ireland
The filing method depends on the taxpayer’s circumstances. Revenue provides several filing routes, including Form CG1, Form 12, Form 11, Form 1 and Form CT1. Taxpayers using Form 11 can report CGT through ROS, while companies generally include relevant information in their corporation tax return. The return may require information about:
- The asset disposed of
- Disposal proceeds
- Acquisition costs
- Allowable expenses
- Chargeable gains or losses
- Reliefs claimed
- Previous losses used
- Taxable gain
- CGT paid
Capital Gains Tax Reliefs and Exemptions in Ireland
Irish tax legislation provides several CGT reliefs and exemptions that can reduce or eliminate tax on a qualifying disposal. Revenue currently identifies reliefs including Principal Private Residence Relief, Revised Entrepreneur Relief, Retirement Relief, Farm Restructuring Relief and relief relating to certain property acquired between 7 December 2011 and 31 December 2014.
Each relief has its own qualifying conditions. The availability of a relief should therefore be established before relying on it when planning a disposal.
Revised Entrepreneur Relief
Revised Entrepreneur Relief can reduce the CGT rate to 10% on qualifying gains from certain business assets. From 1 January 2026, the lifetime limit for qualifying gains increased from €1 million to €1.5 million.
The relief has detailed conditions. For qualifying company share disposals, for example, an individual generally needs to hold at least 5% of the ordinary shares and satisfy specified employment or directorship requirements. Revenue also requires the relevant ownership and service conditions to be met.
The €1.5 million amount is a lifetime limit rather than an annual allowance. Previous qualifying disposals therefore need to be considered when determining how much of the limit remains.
Retirement Relief
Retirement Relief can apply to qualifying disposals of business or farming assets. Despite its name, an individual does not necessarily have to stop working completely to qualify.
The conditions and limits depend on factors including the individual’s age, the type of assets transferred and the person receiving the assets. Revenue provides separate rules for transfers to children and transfers to other individuals. Business owners considering a transfer should review the relief before completing the transaction because the structure and timing of a disposal can affect the available relief.
CGT on Property
Property disposals can require detailed calculations because the tax position may depend on the purchase price, sale price, qualifying improvement expenditure, professional fees, occupation history and periods of letting.
A specific relief applies to qualifying property acquired between 7 December 2011 and 31 December 2014. Where the conditions are satisfied, full relief can apply where the property was owned for at least four and up to seven continuous years. Where the property was held for longer, partial relief may apply based on the relevant ownership period.
This is sometimes referred to as a 7 year capital gains tax exemption, but it should not be interpreted as a general seven-year exemption for every Irish property. The acquisition date, ownership period and other conditions must be checked. Property owners should also consider Principal Private Residence Relief where the property has been their main residence.
CGT Clearance Certificate
A capital gains tax clearance certificate may be required for certain high-value property transactions. Revenue states that a CG50A certificate is required where an asset is sold for more than €500,000, or where a house or apartment is sold for more than €1 million, subject to the applicable rules.
Applications can be made through myAccount or ROS using the Capital Gains Clearance facility. Where the required certificate is not obtained, the purchaser may be required to withhold 15% of the purchase price under Section 980. This makes clearance an important consideration before completing a qualifying property transaction. The vendor should address the requirement early enough to avoid unnecessary complications at completion.
