NPPR 2012 - €200 per unit not per property. 2 flats in one property = 2 charges.
Liability date is 31st March, 2013. You can pay up to the 30th June, 2013. After that there are serious penalties.
NOTE: It is considered by some to be tax deductable. I will be backdating a claim on this, this year. Revenue never did come back with full clarify on it.
To the two posters on AAM in the last month that claims never to have heard of the NPPR, here it is in black and white.
This is the last year it's due.
Local Property Tax. 2 flats in one property = 1 charge. Ditto for granny flats. 2 flats with separate legal title in the same block of flats would be 2 charges
