At the beginning of the article, the purpose and objectives of the research are defined, as well as the materials, methods and conditions for conducting the research. The results of the study and their discussion are presented below. In the article, the authors highlight the problem of transition from the previously existing norms of PBU 18/02 to the new norms applied from 2020. The main part compares the concepts and indicators used in 2019 and 2020 in accordance with the requirements of PBU 18/02. The article also addresses the issues of evaluating work in progress in accordance with the requirements of regulatory legal acts in the field of accounting and taxation. The procedure for applying the norms of PBU 18/02 is shown on a specific example and the calculation procedures made that justify the occurrence of temporary differences that lead to the recognition of deferred income tax, as well as conditional income tax expense and current income tax on the accounting accounts. For clarity and comparison, the indicators for the application of PBU 18/02 in 2019 and 2020 are presented in the tables. In addition, the tables show the schemes of accounting transactions for accounting calculations with the budget for income tax in two ways to determine the current income tax: based on accounting data and based on tax Declaration data. Having considered a specific example of the procedure for applying the norms of PBU 18/02 in the version up to 2020 and in the current version from 2020, the authors conclude that changes in the procedure for identifying temporary differences do not mean a change in their value and the value of net profit
