The proposed glossary is based on terms from the International Glossary of Tax Terms, the OECD Glossary of Tax Terms, the Glossary of Financial and Investment Terms and websites of the Tax Agencies. This dictionary contains the most commonly used terms in the tax field and has about 1600 terms that are of interest to both researchers and professionals in this field. We have paid special attention to the phenomenon that is currently only being implemented in Ukraine, namely the concept of “Base erosion and Profit Shifting” (BEPS), which refers to tax planning strategies that use gaps and inconsistencies in national and international tax law to artificially transfer profits to low- or zero-tax areas where economic activity is low or non-existent. In the future, it is planned to create a Swedish-Ukrainian dictionary of tax terms, which will contain more dictionary entries and help future professionals in this field.
