Hi Barry,
Some good news, first-off, if you made the disposal in 09, then the tax return for this period is not due till 31 October 2010.
Secondly, I understant the Rabo funds accounts are UCITs covered by Chapter 4 part 27 of the Taxes Consolidation act.
The tax liability is currently 28% so long as your tax return is filed correctly. Where your tax return is not filed correctly, then the tax liability jumps to your marginal rate (41%).
In relation to filing your tax return, I would expect the fee to be about €100 including VAT for a stardard Form 11. (You mentioned that you did not have any other income other that the gain on the sale of these shares.)
Also a good tax advisor will take a quick look at your circumstances to see if you can claim any additional credits so you may actually end up with a tax refund.
Also, as your non PAYE income is below €3,174, you may not be considered a chargeable person and therefore no preliminary tax was due last October, instead you liability is paid this October when filing your tax return. This ties in to the information provided on the Rabo website. If you want to pm me, I would be happy to dicuss filing your 2009 tax return.
