Personal income tax (PIT) is one of the most important taxes in Ukraine due to its economic, social and political role. With its help, one can regulate the investment process, the level of real incomes and maintain stability in society. However, the potential of this tax in Ukraine is not fully used. The purpose of the study is to identify the main problems of PIT and further directions of its implementation as an instrument of social policy. Laffer’s tax theory, on the dependence of economic efficiency of taxation on lower tax rates and the degree of progressiveness of taxes, was taken as a conceptual line of research. Consideration of world trends in the practice of PIT allowed tracing its evolution and choose the methods of its optimization that are acceptable for Ukraine. The use of comparative and statistical analyses, grouping, structural modeling method, index method and systematization of results allowed formulating the author’s version of the income taxation reform in Ukraine. The introduction of a progressive taxation scale should take into account the quality of tax administration, the availability of tax benefits, deductions and loans, the amount of fines, and public perception of the tax system in addition to quantitative results. The proposed family taxation, based on the differentiation of taxpayers by their marital status, actual solvency through the introduction of family rates and the establishment of progressive rates of personal income tax, will fully implement the principle of social justice in the distribution of income.

The paper examines, using the example of Ukraine from 2003 to 2020, how and to what extent the development of various segments of the insurance market (risk insurance, life insurance, and reinsurance) influences the overall level of social progress. It also identifies the time gaps through which this influence manifests. The study creates a single measure that looks at various aspects such as social class differences, spending patterns, income changes, and government social spending (their standardized values, weighed by the principal component method, integrated through additive convolution). Using VAR modeling, the impact of the development indicators of different segments of the insurance market (risk insurance, life insurance, and reinsurance) at the current moment and with lags of one, two, and three years is investigated, as well as the level of social progress in Ukraine in previous years. The modeling confirms that social reforms yield significant results for social progress only after three years, similarly to the increase in the number of insurance companies. Given insurers’ assets and payout levels, their growth in life insurance has a faster impact on social progress than in risk, while the opposite is true for premiums. Insurance premiums transferred to Ukrainian reinsurers negatively and slowly (over three years) affect social progress, and to non-resident reinsurers – positively and faster (within a year). Across most indicators, life insurance not only influences Ukraine’s social progress more quickly than others but also provides a more substantial social effect.
