Can I ask if I sell my rental property am I liable for cgt on the Full amount or the difference between the original purchase price and the now value or the difference between the value it was when it ceased being my private residence and the value it is now
Why guess - and get it wrong - when I already posted a link that explains the CGT tax treatment in this situation?
You omitted the fact that the last 12 months/365 days are also exempt even if the property is rented at that time. Also, a more accurate calculation would be done using days rather than round years. The Revenue example uses round years for simplicity and for the purposes of illustration.
