As a holding company for which company - an EU or non-EU company?
If an EU company then there is little advantage over other EU holding companies i.e Cyprus, Estonia, Malta, Bulgaria one etc etc due to EU parent subsidiary .
Actually there seems to be a massive difference when you sell the subsidiary.
I am going to be a >10% shareholder in an EU company and when I sell my shares, I would prefer the sale to be tax free.
Turns out that while even socialist countries like Sweden or Norway would apply the participation exemption for the sale of qualifying shares, Estonia does not. In other words, Estonia would tax your exit from a startup at 20% on the holding company level, while Sweden wouldn’t. Sure, as long as you don’t pay out any profits from the holding company, there is no difference.
But that makes Estonia utterly useless for such a case. It would only be useful for receiving dividends.
Latvia and Lithuania on the other hand don’t tax capital gains from qualifying shares, provided the shares have been held for 3 years or something. And Latvia doesn’t apply withholding tax on dividends paid to a resident of most countries.
The only thing you need to look out for is any substance requirements for the holding company
That’s the thing: Cyprus is a red flag and I’m worried that the other country (not Cyprus) will have additional substance requirements to recognize the holding company. But maybe that’s something to be aware of in general and they may be just as strict with a holding company from Latvia?
