its not only a rented property - it can be ownership too...
u can get some tax relief - providing you are not in arrears and have been paying on time.
see joan burtons statement:
With respect to management company fees, that part of the fees payable by residents to a management company in respect of such ‘service charges’ may, subject to the conditions outlined in the leaflet above, qualify for tax relief up to the €400 limit.
Unfortunately, the remaining elements of the management fees, such as payments towards the upkeep and maintenance of the property and payments towards a sinking fund do not qualify for tax relief.
