With numerous tax changes confirmed in the agreement the following stood out:

Personal income tax, the documents confirm that the income tax structure will be reduced from four brackets to two, of 37% on income up to €68 000 and 49.5% on income exceeding this threshold. At present, personal income is taxed at progressive rates up to 52%, which applies to income exceeding €67 072.

To offset the cost of these tax cuts, it is proposed that the lower rate of value-added tax will be increased from 6% to 9%.

In other tax measures, the coalition has agreed to higher environmental taxes, with a carbon price to be introduced in the electricity sector, and the possible introduction of noise and pollution taxes on the aviation sector, including a flight ticket tax.
