Romania's Government has changed recently and the new one tries to introduce a solidarity tax:
The Romanian Government wants to introduce a new type of tax called the solidarity tax, which will be paid by people who have monthly wages above RON 14,500 (EUR 3,200), said the new finance minister Ionut Misa yesterday.
Some argued that this somehow mirrors the solidarity tax (wealth tax / "ISF") from France (Romania's legislation is highly influenced by the French one).
However, I have read that in France, there were some discussions about removing it. Macron during his mandate as a economy minister suggested scrapping it:
French Economy Minister Emmanuel Macron has suggested that France should scrap its wealth tax and raise inheritance taxes instead, breaking a longstanding Socialist taboo and drawing the ire of Prime Minister Manuel Valls.
This article dives into the details of solidarity tax implementation in France:
In French, ISF means “solidarity tax on fortunes”. But there is very little solidarity, and the number of actual fortunes caught by it is small. As you would expect, anyone with real money finds ways round the tax. Its burden falls instead on those of middling income who cannot afford to pay clever advisers.
The wheezes used to avoid paying the tax are, of course, manifold. If you’ve ever wondered why French people have so many antiques and works of art in their homes, the reason is not just Gallic good taste. Assets over 100 years old, or created by hand, do not count towards the ISF. Other taxpayers make temporary “gifts” of their assets to relatives, without actually having to give them away for ever – though this procedure involves entering another potential fiscal whirlpool, France’s “gift tax”.
Question: is there a reliable source that assessed the solidarity tax impact upon the economy?
I find such an assessment really useful for countries that want to introduce such a tax, to better understand the possible outcome.
