I registerd two properties with them in early dec 04. After receiving no reply I tracked down someone working there and called them. They are inundated with work. They have roughly 70,000 of a backlog to register.
They reckon that there are about 120,000 to 140,000 landlords in this country.
They are so backlogged that they have started cashing in the cheques for fear they will go out of date. Your cheque may be cashed but don't expect to hear anything from them for a while.
To answer the original question, you must register. The fee is 70 euro. They have stamped all forms as they arrived. They have pushed out the deadline to register, but the person i spoke to did not state to what date. I had a feeling that anyone in the backlog would only be charged 70 euro.
The fines for not registering are substantial. Up to 3,000 euro if they find you to be a landlord and not registered. Also I believe that they can fine you 200 euro per day from the date that are requested by them to register but do not.
Mention this to your unregisterd friends !!! 3,000 euro fine, 200 euro per day if they fail to register and a court appearance with a maximum jail sentence of six months.
If they are not aware of the PRTB, they should become aware of it very very quickly .
