Ukraine Overhauls Mobilization Rules Starting April 1: New Checks on Deferments Announced.

Changes to Ukraine's Mobilization Process

According to Novyny.live: Starting April 1, 2026, Ukraine will introduce reforms to its mobilization system. These changes will enable automatic data sharing between the 'Oberih' registry, the Tax Service, and the Pension Fund. The goal is to improve how authorities verify whether military reservists have legally obtained deferments.

New Verification Standards

Under the updated rules, officials will check:

• salary levels;
• payment of the unified social tax (USC);
• the actual existence of the workforce listed by employers.

Deferments for military reservists will be automatically revoked if a company has outstanding debts or if an employee is not actually receiving a salary—indicating fake employment. Additionally, a cap of 50% will be set on the total number of reservists a company can defer, preventing any firm from exceeding the allowed percentage. This means businesses must comply with these new requirements to keep their deferments valid.

These measures are designed to curb abuse in the deferment system and create a fairer mobilization process. By automating checks and tightening oversight, the government aims to reduce loopholes and ensure equal treatment across all enterprises.

The reforms, effective from 2026, are a direct response to challenges in mobilizing reservists in Ukraine. The automation of verification processes and stricter control over deferment legality are intended not only to minimize fraud but also to level the playing field for all businesses. This is especially critical given the ongoing demands on national security and defense.
