Under Russian tax law, a company is a tax resident in Russia if (a) it is incorporated in Russia, (b) its management and central control are in Russia, or (c) if a treaty deems it to be in Russia. Estonia has no tax treaty with Russia, so (c) is not relevant. In your case, (a) is also not relevant. Point (b) is more interesting: do you live in Russia and exercise management of your Estonian company in Russia?

If yes, then you own a Russian-resident company and Russian corporate tax law is applicable. You are required to prepare financial statements and file corporate tax returns in Russia. Presumably there's also many foreign ownership disclosure requirements.

Please consider discussing your case with a tax advisor if you have not already done so. I would never ever easily recommend a citizen of an OECD country incorporate a company overseas without first thoroughly researching disclosure requirements and tax law. Please be careful as tax laws generally are of the "go straight to jail" type.

I wish this Estonian e-residency program would contain more warnings in red about the significant impact such a foreign company will have on a shareholder. This applies to Atlas as well--non-US-residents need to be extremely careful with US corporations as there's a good chance they will not actually be resident in the US.
