The head of AIB says the bank will not pay corporate tax for another 18 or 19 years.
That's despite the bank reporting pre-tax profits of 1.6 billion euro last year.
AIB is allowed to write off tax costs based on previous losses of €3bn during the financial crisis.
AIB CEO Bernard Byrne has told the Public Expenditure Committee that is likely to give them almost two decades of tax-free income.
He said: "We don't definitively know is the answer because obviously, it's a calculation based on profitability at any point in time, so what we gave is a set of estimates based on a prediction of future profitability.
"If you apply for a similar number you end up somewhere between 17-18 years, I think in terms of a projection based on a set of assumptions that ultimately will vary on the actual financial performance of the bank."
