According to the guide, which can be downloaded from the State Tax Service website, the "Taxpayer's Personal Account" provides individuals and legal entities with centralized access to electronic tax services, tax information, and electronic communication with the State Tax Service. Users log in through the State Tax Service portal, which redirects them to MPass, where EvoSign, mobile signature, qualified electronic signature, electronic ID, and two-factor authentication are available. The latter option allows users to log in using an IDNP, password, and verification code without having to use a qualified electronic signature for every session. Upon first login, the user must accept the terms of use and verify or update their contact information. The set of features in the main interface depends on the taxpayer's type and the user's role. For individuals, the account displays personal and contact information and allows users to configure notifications via MNotify, SMS, and email. For legal entities, there is a separate interface, the ability to switch between available companies and roles, as well as access to company documents. Through the "Messages" section, taxpayers can receive announcements, payment notices, and notifications regarding tax returns; access the archive; and send messages and documents to the State Tax Service directly from their account. The "Services" section lists all available electronic tax services, with the list tailored to the taxpayer's category, role, and granted permissions. A separate "Access Management" module is provided for legal entities: an administrator can view the company's users, add new ones, assign and revoke roles and electronic services, modify access rights, and remove users. The system provides, in particular, roles for administrator, director, chief accountant, and accountant, and also maintains a history of changes to access rights.// 09.11.2026 - InfoMarket.
