In the paper we distinguished the dominants of tax policy, taking the challenges of martial law and the special period into account. Also, we systematized the institutional changes in the tax policy after the full-scale war. It was determined that adaptability is the key principle of tax policy formation in Ukraine now.

Authors justified the urgency of suspending the increase in excise tax on tobacco, considering the level of shadow market. The need for a comprehensive tax reform in the post-war reconstruction period has been determined. Practical implications. Tax policy and instruments of its implementation. Conclusions. It is advisable to ensure institutional transformations of tax policy in order to increase its transparency, fairness, and fiscal capacity. It is important to improve the technological component of the tax service development, which would effectively administer taxes and fees, provide high-quality and convenient administrative services to taxpayers. In modern conditions the dominants of tax policy should be: effective fiscal management by increasing the level of work automation, creating conditions for ensuring a stable and protected IT infrastructure, further improvement of the internal control system of the State Tax Service of Ukraine; new quality of taxes and fees administration, taking into account the large-scale challenges associated with the introduction of martial law; comprehensive fight against tax evasion based on the implementation of international standards and improvement of existing analytical tools. The war duration and the significant increase of fiscal deficit determine the need to enhance the fiscal space, which is a vital direction for further research.
