The responsibility for organizing public healthcare, social welfare, and rescue services was transferred from municipalities to wellbeing services counties starting from 2023. The key objective of this reform was to improve the availability and quality of basic public services throughout Finland. Municipal tax revenue was transferred to the central government to finance activities of the wellbeing services counties. Approximately EUR 14 billion in earned income taxes and around EUR 1 billion in corporate income taxes were transferred. Additionally, the central government transfers to municipalities concerning health and social services were cut by approximately EUR 7 billion.
Changes in earned income taxation were implemented within the existing tax system. Municipal tax rates in all municipalities were reduced by 12.64 percentage points, and central government taxation was tightened accordingly. The tightening of central government taxation was achieved by changing the income tax scale and adjusting several parameters for reducing income taxation. At the same time, tax bases for central government and municipal taxation were combined. This meant that from 2023 onwards, income deductions were granted on the same basis and at the same level in both state and municipal taxation.
Changes in earned income taxation were implemented so that they had as little impact as possible on the level of taxation of taxable persons. The purpose of the reform was not to ease or raise the taxation of anyone. As a result more earned income tax is now paid to the central government and correspondingly less to the municipalities. The overall level of taxation has remained almost unchanged. In accordance with the Government Programme, the reform was carried out in such a way that changes in the tax structure did not, upon entry into force, lead to a tightening of taxation on any income level (by more than 0.2 %-points).
Adjustments for inflation and rise of earnings levels were made to the central government tax scale in 2023.
The maximum amount of the basic allowance in municipal taxation was raised from EUR 3 740 to EUR 3 870. The maximum amount of the earned income tax credit in state taxation was raised from EUR 1 930 to EUR 2 030.
Since 2012, the deductible share of home-loan interest has been reduced gradually, and for the tax assessment of 2022, 5% of home-loan interest was deductible. From 2023, the deductibility of interest expenses from home loans was abolished.
