Мой Налог (My Tax) is an Android application developed by the Federal Tax Service of Russia (ФНС России) for self-employed individuals who want to apply for the special tax regime called "Professional Income Tax." The app provides an easy and convenient way for self-employed individuals to interact with the tax authorities without having to visit the office in person.

With Мой Налог, self-employed individuals can apply to become a taxpayer and receive a unique taxpayer identification number, generate receipts without the need for a cash register, send receipts to customers, pay taxes, and track their income statistics. The app also allows users to obtain certificates of registration and income statements.

The special tax regime allows self-employed individuals to pay tax on their income at a reduced rate of either 4% or 6% without additional contributions. The reduced rate applies to income earned from physical and legal entities and individual entrepreneurs. Overall, Мой Налог is a useful tool for self-employed individuals who want to simplify their tax-related obligations.
