Cgt on rented appartment

I have a appt - purchased in Jan 2001. I resided there until Jan 2007. The appt has been rented out since 2007 as I had moved cities due to a job relocation. It was not my intention to have the property as an investment but had no option but to rent it out to cover the mortgage.

I am now buying a 2nd property which will be my main residence.

My appt is now up for sale - my question is am I liable for CGT if and when it sells...

Thanks for any advice

The period you lived in it will be exempt - 6 years (72 months)
The last 12 months of ownership will be exempt (12 months)
Any other proportion of ownership will be taxable.

Say gain was €10,000 and sold in January 2010. (Totla ownership = 108 months)

Taxable gain would be €100,000 x 24/108 = €22,222 (less annual exemption).

Periods of absence due to employment are only exempt if you live in property both before and after the relevant period - so may not apply to you.
