Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
You are liable to taxation in both countries on the gain made on disposal; Profits Tax (PT) in Russia and Capital Gains Tax (CGT) in the UK. However, there is a Double Taxation Treaty between the two countries which precludes the same stream being taxed in both jurisdictions. This is achieved by means of tax credits, the tax paid in one being allowed as a tax credit against the liability in the other. The Treaty does not, however, protect you from differences in rates of taxation. From the data you are quoting, as the maximum UK CGT is at 28% and you have an Annual Exempt Amount (AEA) of 11.3K to offset this, then your UK liability would appear to be nil as any liability would be absorbed by the Russian PT at 30%.
I do hope that you have found my reply of assistance.
