Competent employees

At the end of 2025, the Finnish Tax Administration employed 4,345 people (2024: 4,767), with 119 individuals working at the Incomes Register Unit (2024: 136). The reduction is due to economic restructuring. Because of economic adjustment measures, the number of temporary employees decreased significantly. The lower number of fixed-term employees increased the average age of Tax Administration employees (2025: 47.6 years). In 2026, the number of employees will probably increase slightly.

There has been a long-term trend within the Finnish Tax Administration toward specialist roles, and this trend continued strongly in 2025. At the end of 2025, 54% of Tax Administration personnel worked in specialist roles (2024: 50%). In 2020, this figure was 42%. In 2025, 6.3 days/person-days were used for staff training (2024: 6.1 days/person-days). Sickness absences amounted to 9.6 days/person-days in the entire Tax Administration in 2025 – the same level as in 2023 and 2024.

Metrics and goals

Highlights from the past year: foundation laid for the use of AI in Tax Administration

In the coming years, artificial intelligence will change the workflows and methods of both Tax Administration and our customers. Our goal is to implement AI solutions that improve productivity, work results and quality. To achieve this, we must scale our capabilities and integrate AI into our daily workflows.

Our rollout of AI has been systematic and gradual. The goal has been to ensure that all AI use is secure and fully aligned with regulatory requirements.

The main goal for 2025 was to achieve widespread adoption of Copilot Chat, the first personal AI assistant. For many employees, this was their first experience with AI assistants, so we also studied the basics of AI, such as how to write prompts. Before the rollout, all Tax Administration employees had to complete an online course on the basics and safe use of artificial intelligence.

The rollout took place in stages across different units, which were allowed to define their own objectives and develop ideas for suitable uses of AI in their work, taking the Tax Administration’s policies into account. As part of the project, responsibility networks were created within the units, with key users playing a vital role during implementation and beyond.

Highlights from the past year: collaboration with Ukrainian Tax Administration initiated

In early 2025, we launched a joint development project aimed at building trust in the Ukrainian tax administration as a competent, high-quality organisation. Our cooperation strengthens the State Tax Service of Ukraine's ability to comply with international standards.

Work is carried out across three key areas, focusing on stakeholder collaboration, integrity, and the management and implementation of reforms and initiatives to strengthen trust. Indirectly, the work supports Ukraine’s integration into the EU.

The most important achievement of the first year of collaboration was the building of trust between the parties, which will serve as the foundation for cooperation in the years to come. The work in different result areas was divided into practical activities, all of which were launched during the first ten months.

Online anti-money-laundering and anti-corruption training, applying Nordic expertise, is delivered as modules. The theme for the new Whole of Government pilot programme was selected from the field of combating the grey economy.

Development of the operations of the State Tax Service using a project model is a key development target. The STS officially launched a Code of Ethical Conduct project, which the agency will use to practice project management methods and tools in action. Several other projects are under preparation.

The utilisation of institutional risk-management maturity assessments has been agreed upon, and the security themes that are addressed have been prioritised. The comprehensive approach of Tax Administration's training offering has made a strong impression on the Ukrainians.

In supporting strategy work, the focus was confirmed to be on implementation support. Regarding the strengthening of trust, it was agreed that a general organisation-level survey method will be created for STS, and development targets also include metrics and methods to improve the follow-up processing of survey results. Internal communications infrastructure and practices have been identified as another key development target at the State Tax Service.

The cooperation project will run until the end of 2028, with project funding of EUR 1.6 million from the Finnish Ministry for Foreign Affairs.
