non resident deposit account

my accountant has told me that if i am non resident with an Irish deposit account, that Ireland is also allowed to tax the interest but the maximun rate of tax it can apply is 10%. Anybody who has been/is non resident have any experience of this ?

Are you a resident of the Republic of Ireland with a non resident account in a bank oustide the Republic of Ireland?
