Are there international treaties preventing states from taxing property transfers out of it?
<p>With the goal of discouraging companies and high net worth individuals from leaving the country to save taxes by taxing wealth leaving the country by a multiple of the taxes due per year if they stayed.</p>

<p>With "state" I mean a sovereign state which nationally can do whatever it wants, I'm only asking about international treaties/laws.</p>

<p>Purely hypothetical question, sorry if this shows a lack of basic understanding on my part. To me it seems like that would be qualitatively similar to the transaction tax some people have been proposing.</p>

<p>I am not aware of any such treaties (although some free trade treaties such as the treaties forming the EU may have that effect among members nations). Limitations on removing assets from a country aren't that uncommon. Many countries have them and more have had them historically. There is a small sub-field within economics that examines the effect of such restrictions.</p>
