How PPR relief shelters your home from CGT

When you sell your own home in Ireland, Principal Private Residence relief normally wipes out the entire gain from CGT, because you lived there for the whole period of ownership. The relief becomes a calculation only when you sell a property that was your PPR for some years but not all. This happens when a property is first lived in and then let, or when someone inherits a property they never occupied. The taxable portion is simply the gain multiplied by the fraction of ownership years that were not PPR years, with the final 12 months of ownership always counting as PPR regardless of actual occupation.

A common situation is the accidental landlord, someone who moved out, started renting the old home, and eventually sells. If they owned for eight years and lived there for four, half the gain is sheltered and half is taxable at 33%, subject to the 1,270 euro annual exemption. This calculator works through that arithmetic so you can see the CGT before calling a solicitor.

A worked example: eight years owned, four as PPR

Take a property bought for 250,000 euro and sold for 420,000 euro. The total gain is 170,000 euro. The owner lived there for four years out of eight, so the PPR fraction is 4/8, which is 50 percent. PPR relief of 85,000 euro comes off, leaving a chargeable gain of 85,000 euro. After the 1,270 euro annual exemption the taxable gain is 83,730 euro. CGT at 33% is 27,631 euro. The proceeds after CGT are 392,369 euro, making the effective tax rate on the total gain about 16 percent, much less than the headline 33% because of the PPR shelter on the occupied half.

Costs that reduce the gain

Your allowable cost is not just the purchase price. You can add stamp duty paid on acquisition, solicitor fees at purchase and at sale, estate agent commission, surveyor fees, and the full cost of capital improvements such as extensions, new bathrooms, or a converted attic. Running repairs and maintenance do not count, and mortgage interest is not allowable for CGT purposes on a main home. Keep invoices and receipts for improvements made during ownership, because they directly reduce the taxable gain, and Revenue will ask for evidence if the figures are large.

Frequently asked questions

How does Principal Private Residence relief work for Irish CGT?
PPR relief exempts the portion of the gain that relates to the years you lived in the property as your main home. The relief is calculated as years of PPR occupation divided by total years owned, multiplied by the full gain. The final 12 months of ownership always count as PPR even if you are not living there, which helps sellers who have moved out before completing. Only one property can qualify as your PPR at any time.
What is the CGT rate and annual exemption on Irish property?
Capital Gains Tax on Irish property is charged at 33% on the taxable gain. Every individual has a 1,270 euro annual personal exemption that reduces the taxable gain before the 33% rate applies. The exemption cannot be transferred between spouses, though each person who co-owns the property can apply their own exemption to their share of the gain.
Can I add buying and selling costs to my base cost?
Yes. Allowable expenditure includes the purchase price, stamp duty paid on acquisition, solicitor and surveyor fees at purchase and sale, and the cost of capital improvements such as extensions. Running maintenance costs and mortgage interest are not allowable. Adding legitimate costs reduces the gain and therefore the CGT, so keeping receipts for improvements over the years can materially lower the final bill.
When do I pay CGT on an Irish property sale?
Gains arising between 1 January and 30 November must be paid by 15 December of the same year. Gains arising in December must be paid by 31 January of the following year. Payment is made via Revenue Online Service before filing the Form CG1 or Form 11 return. Late payment attracts interest, so the payment date matters even if the return deadline is later.
