The Government is said to be considering a new tax rate to ease pressure on middle-income earners as the cost of living continues to rise.
Tánaiste Leo Varadkar said a new rate of 30 per cent is being examined by Minister for Finance Paschal Donohue to see if it is possible.
At present, a single person earning up to €36,800 a year pays income tax of 20 per cent, while any yearly income above that level for a single person is taxed at a rate of 40 per cent.
