Bank interest taxation

My query is simple. What is the rate of tax on bank account interest (assuming earnings are taxed at the higher rate). I searched the Revenue site already and cannot find an answer there. Also is interest earned on SSIA accounts liable for more income tax not already deducted by the bank also ?

Thanks,
Mark

Interest on Irish bank accounts is normally (some exemptions apply) subject to 20% DIRT deducted at source and the account holder has no further liability for tax on such income. I'm not sure if PRSI may be an issue if the amount if interest earned is over a certain threshold though.
