Tax Refund

Hello. I am about to submit P60 to revenue to check if I am due a tax refund (or owe some) for 2011. I also have a rental property which I am ready to submit the accounts for 2011- my question is do I have to wait till october to submit the rental account info? Or can I do it all now? -NOTE :- this is first yeat tax for rent is being submitted, i.e. 2011

You can fill out the form 11 now (or form 12 if within the limits)
