A Revenue "payment processing" error has led to a large number of people being wrongly debited thousands of euro from their bank accounts.
The Irish Times reports that 1,500 people have been affected, with more than €830,000 taken in total.
The local property tax deductions were made despite homeowners having agreed with Revenue to have the money debited in the New Year.
Revenue says it is in the process of contacting affected taxpayers about the error and receiving refunds.
Revenue said they had “fully resolved” the problem and that people would be refunded any fees or charges imposed by their banks as a result of the mistake.
They said: “Revenue is now in the process of contacting, and returning the payments to, the affected customers.”
“22% of customers have confirmed they do not wish to receive a refund, 24% of refunds have been approved on Thursday, while it is expected a further 52% will be approved today.
“While the issue is now fully resolved, Revenue has acknowledged, and sincerely apologised for, the inconvenience caused to the affected customers.”
