However can I jump back to my 2004 situation. I started renting out my appt in July (6mts for 04) and recieved €5160 in rent - this is under the rent a room limit by €2460. Can I now in theory back date a rental increase for 04 to maximise my RaRS limit i.e €7620. Hence I don't know my tennants as much overall. I would owe them €1350 for 05 and they owe me €1230 for 04. Balance I owe them is €120ea. Is this possible. ANain I ran this by Revenue and the "advise" I got would be that this is ok. All that would appear on my return for 04 is €7620 and the same for 05. Should I ask revenue for this in writing or get an accountants or tax advisors advice.
This looks a rocky road to go down. Your return for 04 is overdue. It should have been made last October and if it had been made then you would have placed a value of E5160 on your 04 rental income. There isn't a credit associated with the rent a room scheme that you can carry forward.
A lot of the time the advice you get from Revenue will be the advice you want to get off them. This can come about through asking leading questions whereby you have, deliberately or not, left out relevant details. Or the person on the other end may simply not be qualified enough to give you the right answer. You could be talking to a 18 year straight out of doing the Leaving cert when you should be spending a few quid on getting a qualified professional to give you the correct answer, not the answer you want to hear.
