I feel there has been/is a OECD crusade around the world forcing countries to consider tax transparent (no change in the status of the source of income) any entity considered tax transparent in its country of origin. Mauritius is the perfect example, where their laws allow (I did not read the laws, just read it was the case) to transform whichever type the income of a tax transparent entity into a dividend (while extracting it to the parent Mauritius company)︀ but despite their laws allowing it, the tax authorities there have made a statement in︁ 2022 that they won't accept anymore that trading income from a transparent entity be transformed︂ into a dividend while extracting it to the parent Mauritius entity (dividends have a much︃ reduced taxation rate in Mauritius)
In mother EU, anti hybrid rules takes care of that.︄
Do you have example of countries who consider a US LLC or maybe even a︅ partnership as tax opaque?
