The phenomenon of overregulation applies to all sectors, including institutions of the pension market. They have to function with an increasing number of obligations, both quantitative and qualitative. Although this translates into a higher level of security offered to clients, at the same time huge costs are generated, especially compliance costs. Their systematic increases may adversely affect the efficiency of pension market institutions. The implementation of RegTech tools can be a way to reduce these costs and improve efficiency at the same time. Thanks to the use of modern technologies, they can support the day-to-day functioning of the institution. Their implementation enables quick adaptation to the changing regulatory environment. At the same time, the technology gap between institutions of the pension market and their supervising institutions is narrowing. The aim of the article was to present the possibilities offered by RegTech. The hypothesis was adopted that implementing RegTech tools will reduce compliance costs, which will translate into improved efficiency. The applied research methods include the descriptive method, the method of literature analysis and the method of logical inference. The benefits of using RegTech presented in the article confirmed the adopted hypothesis. Tools included in this group are focused on long-term operation, therefore they have a real impact on the efficiency of these institutions, especially cost efficiency.
