Capital Gains Tax on a Second Home or Rental in Lucan: What Sellers Pay
When you sell a second home or rental property in Lucan, you usually pay capital gains tax at 33% on the profit. Your gain is the sale price minus the purchase price and allowable costs. However, the first €1,270 of gains each year is tax-free. Principal Private Residence relief can also cut the bill if you once lived there.
Why Second-Home Sellers Get Caught Out
Capital gains tax on a second home catches many Lucan sellers off guard. Because your family home is normally exempt, it is easy to assume the same rule covers the starter home you let out when you moved. Similarly, many people assume it covers a house they inherited from a parent.
Unfortunately, it does not. Once a property stops being your main home, Revenue treats part or all of any increase in value as a taxable gain. Since Lucan values have risen strongly over the past decade, the sums can be significant.
This guide explains how the tax works, which reliefs apply and when you must pay. It also shows how timing your sale can make a real difference.
How Capital Gains Tax on a Second Home Works
Capital Gains Tax (CGT) applies to the profit you make when you dispose of an asset. According to Citizens Information, the standard rate is 33%. In addition, the first €1,270 of chargeable gains in a tax year is exempt.
The exemption is personal. So if a married couple owns a property jointly, each spouse can use their own €1,270. However, one spouse cannot transfer an unused exemption to the other.
What Counts as a “Second Home”?
For CGT purposes, Revenue can tax any residential property that was not your only or main residence for the entire time you owned it. For example, that includes:
- A buy-to-let apartment or house you bought as an investment
- Your former home, which you let out after you moved (the “accidental landlord”)
- A holiday home or pied-à-terre
- An inherited house that you sell rather than live in
- A property you bought so a family member could live in it
How to Calculate the Gain
The basic formula is simple:
Sale price − selling costs − purchase price − buying costs − improvement costs = chargeable gain
Next, you deduct any reliefs, the €1,270 annual exemption and any allowable losses. Finally, Revenue taxes the balance at 33%.
Costs You Can Deduct (and Costs You Can’t)
Getting your deductions right is the easiest way to reduce your bill legally. In general, Revenue allows money that adds value to the property, as well as the costs of buying and selling it.
Usually Deductible
- Purchase price, or market value at the date of inheritance if you inherited the property
- Stamp duty you paid when you bought
- Solicitor’s fees on both the purchase and the sale
- Estate agent fees and advertising on the sale
- Valuation and BER certificate costs connected to the sale
- Improvement (enhancement) costs, such as an extension, attic conversion or new kitchen, as long as the property still reflects them when you sell
Usually Not Deductible
- Mortgage interest
- Routine repairs, maintenance and redecoration
- Any cost you already claimed against rental income for Income Tax
- Your own time or labour
Above all, keep every receipt. If you bought your Lucan property ten or fifteen years ago, start gathering old solicitor’s statements and invoices now. Otherwise, missing paperwork means lost deductions.
Principal Private Residence Relief: The Biggest Saver for Accidental Landlords
If you lived in the property as your main home for part of your ownership, you can claim partial Principal Private Residence (PPR) relief. Revenue sets out the rules in its PPR relief guidance.
Key PPR Rules
- Relief is time-based. You only get relief for the share of your ownership when you lived there.
- The last 12 months count as occupation, even if you let the property or left it empty.
- Working abroad can also count as occupation when you carried out all your employment duties outside Ireland, in certain circumstances.
- Employer relocation counts too, when your employer required you to live elsewhere, up to four years.
- Grounds of up to one acre around the house qualify, excluding the site of the house itself.
- Rent-a-Room Relief does not affect PPR, so taking in a lodger won’t reduce your relief.
The occupation rules are complex, and the conditions around absences are strict. Therefore, ask your accountant to confirm exactly which periods qualify before you rely on them.
Worked Example: An Accidental Landlord in Lucan
The figures below are illustrative only and do not relate to a specific property.
Aoife bought a two-bed townhouse in Lucan in June 2015 for €260,000. She also paid €5,000 in stamp duty and legal fees. After living there for four years, she moved in with her partner and let the house for seven years.
In 2026, she sells for €480,000 and pays €9,000 in agent and legal fees. As a result, her total ownership is 11 years.
Aoife’s CGT Calculation
| Step | Calculation | Amount |
|---|---|---|
| Sale price | €480,000 | |
| Less selling costs | −€9,000 | |
| Less purchase price and buying costs | €260,000 + €5,000 | −€265,000 |
| Gain before relief | €206,000 | |
| PPR relief | 4 years lived + last 12 months = 5/11 | −€93,636 |
| Chargeable gain | €112,364 | |
| Less annual exemption | −€1,270 | |
| Taxable gain | €111,094 | |
| CGT at 33% | €36,661 |
What the Example Shows
If Aoife had never lived in the property, her CGT would have been roughly €67,561. In other words, her four years of occupation, plus the final 12 months, saved her about €30,900.
Furthermore, if she owned the house jointly with a spouse, each would claim their own €1,270 exemption. In that case, the total bill would fall slightly, to around €36,242.
Other Reliefs That May Apply
PPR is the most common relief for Lucan sellers. That said, it is not the only one, so check the table below before you sell.
| Relief | Who It Helps | How It Works | Source |
|---|---|---|---|
| Principal Private Residence | Owners who lived there for part of the ownership | Exempts the share of the gain for time lived there, plus the last 12 months | Revenue.ie |
| 7-year relief (property bought 7 Dec 2011 – 31 Dec 2014) | Investors who bought during the market low | Held 4–7 years: full exemption. Held longer: 7 ÷ years owned of the gain is exempt | Revenue.ie |
| Indexation relief | Owners who bought before 2003 | An inflation multiplier increases purchase costs you paid up to 31 December 2002 | Revenue.ie |
| Annual exemption | Every individual | First €1,270 of gains each year is tax-free | Citizens Information |
| Allowable losses | Sellers with losses on other assets | Losses on other disposals can reduce the chargeable gain | Citizens Information |
| Spouse transfers | Married couples and civil partners | Transfers between spouses are exempt, and the receiving spouse takes over the original cost | Citizens Information |
The 2011–2014 Relief Is Worth Checking in Lucan
Many Lucan properties changed hands at the bottom of the market between 2011 and 2014. Consequently, if you bought during that window, this relief may exempt a large share of your gain.
For instance, suppose you bought in early 2013 and sell in 2026. You have then owned the property for about 13 years, so roughly 7/13 of the gain would be exempt.
CGT Payment Dates and Filing Deadlines
For CGT, the date of disposal is generally the date of the contract, not the closing date. This detail decides which tax year your gain falls into and, therefore, when you must pay.
| If You Sign Contracts | Pay CGT By | File Your Return By |
|---|---|---|
| 1 January – 30 November 2026 | 15 December 2026 | 31 October 2027 |
| 1 – 31 December 2026 | 31 January 2027 | 31 October 2027 |
| 1 January – 30 November 2027 | 15 December 2027 | 31 October 2028 |
Source: Citizens Information
You must file a return even when you owe no tax, for example where reliefs cover the whole gain. In practice, most landlords already file a Form 11 for rental income, so they report the gain there.
Why Timing Matters This Autumn
If you go sale agreed in Lucan this autumn, your contract date can change your cash flow:
- Sign by 30 November: CGT is due by 15 December 2026, possibly before or close to your closing date.
- Sign in December: instead, you gain an extra six weeks, with payment due 31 January 2027.
- Sign in January 2027: the gain then falls into the 2027 tax year, with a fresh €1,270 exemption and payment not due until 15 December 2027.
The Government will announce Budget 2027 in October 2026. So check whether it brings any CGT changes before you commit to a contract date.
CGT Clearance: Will the Buyer Withhold 15%?
When you sell a house or apartment for more than €1 million, you must give the buyer a CGT clearance certificate (Form CG50A). Otherwise, the buyer must withhold 15% of the purchase price and pay it to Revenue, according to Revenue’s clearance guidance.
Most Lucan homes sell below this threshold, so clearance rarely applies. However, larger detached homes on bigger sites may need it. For that reason, raise it with your solicitor early.
Common Mistakes Lucan Landlords Make
- Losing old paperwork, because without receipts you cannot prove your costs
- Assuming the family home exemption still applies after you let the property
- Forgetting the tax is due within weeks, rather than with next year’s tax return
- Ignoring the contract date and accidentally pulling a sale into an earlier tax year
- Overlooking the 2011–2014 relief, even though it can exempt a large share of the gain
- Not budgeting for other selling costs, such as agent fees, legal fees and any outstanding LPT

Frequently Asked Questions
Do I pay capital gains tax when I sell a rental property in Ireland?
Yes, in most cases. You pay CGT at 33% on the gain after you deduct your purchase price, buying and selling costs, and qualifying improvement costs. However, the first €1,270 of gains each year is exempt. Also, if you lived in the property as your main home at any point, partial Principal Private Residence relief may reduce the bill.
How can I reduce capital gains tax on a second home in Lucan?
Firstly, claim every allowable cost, including stamp duty, legal fees, agent fees and improvement works. Secondly, check whether you qualify for partial PPR relief for years you lived there, or for the relief on property bought between December 2011 and December 2014. Finally, if you own jointly, each owner can use their own €1,270 exemption.
Do I pay CGT on a house I inherited and then sell?
Only on any increase in value since you inherited it. Your base cost is the property’s market value at the date of death, so a formal valuation at that time is important. As a result, if you sell soon after inheriting, the gain is often small. Separately, Capital Acquisitions Tax rules apply to the inheritance itself.
When do I have to pay CGT after selling a property?
It depends on your contract date. When you sign between 1 January and 30 November, CGT is due by 15 December of the same year. For December contracts, however, it is due by 31 January of the following year. You must also file a return by 31 October of the following year.
