In 2018, the Federal Tax Service of Russia received the first data on the foreign bank accounts of Russian tax residents. I don’t think the tax authorities have enough resources to process all the information they’ve received, however, as the skills, practices, and instruments of automation of Russia’s tax authorities improve, they will gradually use this data more effectively in order to increase the volume of tax collected from Russians’ foreign incomes.
Naturally, Russia’s tax authorities will primarily be interested in cases involving larger amounts of money, but eventually they will also focus on less high profile cases.
The steady rise of the number of Russians reporting both foreign accounts and CFCs can be explained by the fact that more HNWIs understand that if they want to remain a tax resident of Russia, they need to notify the authorities. There’s only one legal alternative: stay in Russia for no longer than 183 days a year and cease to be a tax resident.
