The revenue publishes an annual “Statistical Report” containing additional analysis of the tax revenue for the year.
The latest available is the 2009 report with data from 2008.

One of the reports is the 'Income Distribution Statistics"
This shows the number of tax units, their total income and the total income tax they paid for 2008.
I have tried to add PRSI and USC calculations to this based on the current rates. This is a long way from perfect as obviously incomes and other tax rates will have altered massively since then! but the best I can do with the data available.

If you include Income Tax, USC and PRSI the maximum effective rate is 44.2% for those earning over €275,000. There are less than 10k tax units in this category and they pay 13.1% of all taxes on income.
The richest 1.5% (19k people) earn 13% of all income and pay 23.3% of all tax.
Almost one third of the tax units in the state survive on less than €17k.
The top 9% earn one third of the income.
The median tax unit income in 2008 was approximately €26k.
