Russia has a flat 13% personal income tax.
“Personal income tax (PIT) is levied individually normally at 13 percent. There is no joint filing. Employers withhold income taxes, thus the taxpayers whose only taxable income was paid by employer do not need to file a tax return—except to claim a refund for itemized deductions. “

Also —in Russia there is basically NO capital gains tax, if you owned the asset longer than 3 years.
“Capital gains from asset sales are taxable only if the seller owned the asset for less than 3 years. “
