Am i right in saying that at this point I just calclate my liability and submit payment and that this time nexy year i will need to submit details on gains i.e i just tell revenue i have a EUR 600 liability for this year with no further details and provide details, reciepts etc this time next year.
Correct pokerhead. If you made the gain between Jan and Sept 2005 then you must only make the payment by Oct 31st. By Oct 31st 2006 you must file your 2005 tax return and show the computation then.
