Personally none - I pay taxes in my home country and everyone is happy. The company rules (delayed income tax, income tax rate) might be subject to treaty that defines "command and control" - that is if the company is really located in Estonia or is it effectively in your home country? If you have an actual office or co founders from other countries or some other vague "company is actually located in estonia", then there are no tax implications of that, other than your personal income.
