If you sell a property being non resident of Russian Federation, you will have to pay 30% tax of the sale’s price! By using the right financial structuring, a recently voted law allows you to lower this tax down to 15% of capital gain only.
Standard tax rate for rental incomes in Russia is 13% for resident of Russian Federation, and 30% for non residents. However, it is possible to reduce this tax to 6% (or sometimes less) for both resident and non resident by using the status of auto-entrepreneur, and different levers associated to it. Check this carefully!
