Capital gains tax - 25.5% on the difference between the sale price and the purchase price, less documented investments. Example: bought for €60,000, invested €10,000, sold for €100,000 - tax is 25.5% of €30,000 = €7,650. No tax is due if you have owned the property for more than 60 months and it was your declared residence for at least 12 consecutive months, or it is your only property owned for more than 60 months, or your only property and the proceeds are reinvested in another home within 12 months. We'll check your case before going to market - sometimes moving the deal by a couple of months saves thousands of euros.
