Capital gains tax on a second home in Ireland: rates, exemptions, and worked examples

Do you pay capital gains tax when selling a second home in Ireland?

Under Irish tax law, selling any residential property that is not your principal private residence is a disposal of a chargeable asset. Whether the property is a coastal holiday cottage in West Cork, a townhouse in Galway, or an investment property in Dublin, any profit realised above your acquisition and improvement costs is subject to Irish Capital Gains Tax (CGT).

For the 2026 tax year, Revenue (revenue.ie) assesses Capital Gains Tax on residential property at a standard flat rate of 33%. Unlike the United Kingdom or the United States, where your capital gains tax rate depends on your overall employment income or marginal income tax bracket, Ireland applies the flat 33% rate uniformly to individuals regardless of their salary, pension, or business earnings.

The tax is levied strictly on the capital gain, never on the gross sale proceeds. If you sell a holiday home for €420,000, you do not pay 33% on €420,000. You pay only on the net increase in value after deducting what you paid to purchase the property, the direct legal and stamp duty costs of buying and selling, qualifying capital enhancement expenditures, and your annual statutory tax-free exemption.

How do you calculate capital gains tax on an Irish second home?

Calculating your Irish Capital Gains Tax liability follows four statutory stages defined in the Taxes Consolidation Act 1997:

• Gross sales proceeds: The contract sale price agreed with the buyer, minus allowable disposal costs such as estate agent fees, auctioneer commissions, and legal conveyancing.
• Base cost: The original purchase price paid when you acquired the property, plus allowable acquisition costs including Irish Stamp Duty (typically 1% on residential purchases up to €1 million) and solicitor conveyancing fees.
• Enhancement expenditure: Capital additions and permanent structural improvements made during your ownership, such as building an extension, converting an attic, or installing central heating, provided they remain reflected in the property at the time of sale.
• Annual personal exemption: Under Section 601 of the Taxes Consolidation Act 1997, every individual receives a personal exemption of €1,270 per tax year, deducted directly from their net chargeable gain.

Consider a typical scenario in 2026: an owner purchased a secondary residence in 2014 for €220,000. Over years of ownership, they incurred €6,000 in acquisition costs (solicitor fees and stamp duty), spent €30,000 adding an extension and upgrading insulation, and incurred €14,000 in auctioneer commission and legal fees when selling for €420,000.

Their total allowable costs equal €50,000 (€6,000 + €30,000 + €14,000). Subtracting the purchase price and allowable costs from the sale proceeds yields a net chargeable gain of €150,000 (€420,000 - €220,000 - €50,000).

Applying the individual personal exemption of €1,270 reduces the taxable gain to €148,730. Taxed at Revenue's statutory rate of 33%, the total Capital Gains Tax payable is €49,081. The seller retains €100,919 of their €150,000 profit, representing an effective tax rate of 32.7%.

How much capital gains tax do you pay across different sale prices?

Because Irish property values range from rural cottages to high-value coastal retreats, it is vital to model tax liabilities at multiple sale prices. The table below details the exact tax due for a property bought for €220,000 with €50,000 in allowable expenses across six realistic sale prices.

On a €280,000 sale (net gain €10,000), the single owner pays €2,881 (effective rate 28.8%), while joint owners pay €2,462. On a €750,000 sale (net gain €480,000), single-owner tax reaches €157,981, and the effective rate converges to 32.9%.

Joint ownership consistently saves €419 (€1,270 × 33%) across every profitable price point because each co-owner claims a separate €1,270 exemption against their half of the gain.

What allowable expenses and improvements reduce your Irish capital gain?

Under Section 552 of the Taxes Consolidation Act 1997, Revenue allows taxpayers to deduct specific costs wholly and exclusively incurred in acquiring, enhancing, and disposing of the property. Claiming all qualifying deductions is the most effective legal method to reduce your capital gains tax bill.

Deductible costs fall into three distinct categories:

• Acquisition costs: The original purchase price, Irish Stamp Duty paid on the deed of transfer, solicitor conveyancing fees, Land Registry fees, and professional surveyor or structural engineering fees incurred at purchase.
• Enhancement expenditure: Capital money spent that permanently enhances the value of the asset and is reflected in the state of the property when sold. Examples include adding an extension or conservatory, installing a new central heating system, rewiring, modernising insulation, or building boundary walls.
• Disposal costs: Auctioneer and estate agency sales commissions, advertising costs, energy performance certificate (BER) assessments, and legal fees paid to your solicitor to handle contracts and conveyancing on the sale.

Equally important are expenses that Revenue strictly prohibits from capital gains deductions:

• Routine repairs and redecoration: Painting, repointing, servicing boilers, cleaning gutters, replacing broken window panes, or garden maintenance. These are operational expenses, not capital additions.
• Mortgage financing charges: Mortgage interest, loan arrangement fees, and broker commissions cannot be deducted for Capital Gains Tax.
• Carrying costs: Local Property Tax (LPT), home insurance premiums, management company service charges, and utility standing charges.

As demonstrated in the comparison table, failing to retain documentary proof for €50,000 of legitimate costs inflates the taxable gain by €50,000, triggering an extra €16,500 in tax payable to Revenue. In the event of a Revenue audit, claims without original contractor invoices, itemised receipts, or bank statements will be disallowed.

Can you claim Principal Private Residence relief if you once lived there?

Many secondary properties in Ireland were not purchased as holiday homes originally. Often, an owner bought a home, resided in it for several years, and subsequently retained it as an investment or second residence after moving elsewhere.

Under Section 604 of the Taxes Consolidation Act 1997, Principal Private Residence (PPR) relief provides full tax exemption for the portion of ownership during which the property served as the owner's sole or main residence. If the property was your main home for part of the ownership, you receive partial PPR relief.

Revenue calculates partial PPR relief using the statutory fraction:

Relief Fraction = (Months of Actual Occupation as Main Home + Last 12 Months of Ownership) divided by Total Months Owned.

The final 12 months of ownership are deemed by Irish law to be a period of occupation as your main residence, whether you lived in the property during that year or not, provided you lived in the property as your main home at some point during your ownership.

The table below illustrates how partial PPR relief reduces capital gains tax on an Irish property owned for 15 years (180 months), bought for €220,000 and sold for €420,000 with €50,000 in allowable deductions (raw gain €150,000), across varying periods of primary occupancy.

If the owner never lived in the property, zero relief applies, resulting in a tax bill of €49,081. Residing in the property for three years (36 months) triggers the deemed 12-month addition, granting 48 months of relief (26.7%). This shelters €40,000 of the gain, bringing the tax down to €35,881—saving €13,200.

Does indexation relief reduce capital gains tax on pre-2003 properties?

If you have held a second home or holiday property in Ireland for several decades, Indexation Relief (also known as inflation relief) may significantly reduce your taxable gain.

Under Section 556 of the Taxes Consolidation Act 1997, Revenue permitted taxpayers to multiply their original acquisition cost and pre-2003 enhancement expenditures by statutory inflation multipliers based on the Consumer Price Index. While indexation relief was abolished for expenditures incurred on or after 1 January 2003, it remains fully applicable to allowable expenditure incurred up to 31 December 2002.

For example, consider a holiday home purchased in 1996 for €80,000 and sold in 2026 for €320,000 with €12,000 in selling costs:

• Without indexation: Net capital gain equals €228,000 (€320,000 - €80,000 - €12,000). Deducting the €1,270 exemption leaves €226,730 taxable, producing a tax liability of €74,821.
• With 1996 indexation (multiplier 1.251): Revenue adjusts the allowable cost base from €80,000 up to €100,080 (€80,000 multiplied by 1.251). This provides €20,080 in statutory indexation relief.
• Tax outcome: The net chargeable gain falls to €207,920. Deducting the €1,270 exemption leaves €206,650 taxable, reducing the CGT payable to €68,195.

Claiming the statutory indexation multiplier saves the seller €6,626 in tax. Revenue's official multiplier table sets specific rates for every year from 1974/75 (multiplier 7.528) up to 2002 (multiplier 1.049). Under Irish tax rules, indexation relief cannot be used to create or artificially increase a capital loss.

When is the deadline to pay and file capital gains tax in Ireland?

Ireland enforces a strict "Pay and File" system for Capital Gains Tax. Unlike Irish income tax, where tax is typically calculated and paid in the autumn following the tax year, Capital Gains Tax must be paid within the same calendar year as the disposal for most transactions.

Revenue divides the calendar tax year into two distinct payment windows:

• Initial Period (Disposals between 1 January and 30 November): You must pay the Capital Gains Tax due to Revenue on or before 15 December of the same year. If you exchange contracts on a second home on 15 May or 20 October, your tax payment is due by 15 December of that same year.
• Later Period (Disposals between 1 December and 31 December): You must pay the Capital Gains Tax due on or before 31 January of the following year.

In addition to paying the tax, you have a mandatory legal obligation to file an annual Capital Gains Tax return by 31 October of the year after the disposal:

• PAYE individuals: File Revenue Form CG1 (Capital Gains Tax Return) by 31 October following the year of sale.
• Self-assessed individuals: Include the disposal details on Form 11 when filing via the Revenue Online Service (ROS), which typically extends the deadline to mid-November.
• Sales at a loss or no gain: You must still file Form CG1 reporting the disposal, even if no tax is due, to declare the transaction and preserve allowable capital losses for future offset.

What mistakes do Irish second home sellers make most often?

• Confusing contract exchange with closing date: Under Section 542 TCA 1997, the date of disposal is the contract date. Exchanging contracts on 28 November but closing in January means tax is due on 15 December of the contract year, not the following year.
• Missing the 15 December payment deadline: Many sellers assume property tax payments coincide with self-assessment filing in October of the following year, triggering unexpected Revenue interest penalties.
• Assuming the €1,270 exemption transfers between spouses: The CGT personal exemption is strictly individual. If a second home is registered in one spouse's sole name, only a single €1,270 deduction can be claimed against the gain.
• Failing to claim the final 12 months under PPR relief: If you resided in the property as your main home at any point, the final 12 months are deemed occupation under Section 604, reducing the taxable portion.
• Discarding invoices for capital improvements: Without original receipts, bank records, and contractor invoices, Revenue auditors will disallow enhancement expenditures, taxing the gross difference.
• Attempting to deduct repairs and Local Property Tax: Painting, maintenance, boiler repairs, mortgage interest, and Local Property Tax (LPT) are completely non-deductible for Capital Gains Tax purposes.
• Neglecting indexation relief on pre-2003 acquisitions: Properties purchased before 2003 are entitled to indexation multipliers that adjust base costs upward and significantly lower tax payable.
• Omitting the disposal when selling at a loss: Capital losses must be formally reported on Form CG1 or Form 11 to Revenue in order to be carried forward against future capital gains.
