🚨New working paper🚨 In this updated work with Annette Alstadsaeter, @bluebery-planterose.com , @gabrielzucman.bsky.social and @andokl.bsky.social , we use leaked data to chart the rise of offshore real estate in Dubai www.taxobservatory.eu//www-site/up...

Matching the Forbes 400 to tax data finds that they pay a total tax rate of 24 percent of economic income, lower than the 30 percent tax rate paid on average in the US, from Akcan S. Balkir, Emmanuel Saez, Danny Yagan, and Gabriel Zucman https://www.nber.org/papers/w34170

New Bureau of Economic Analysis data: In 2023 US multinationals booked 42% of their foreign profits in the main tax havens After 2 years of unprecedented decline, profit shifting seems to be rising again Back to the lung-run trend that started in 1978?

Think how much you pay in taxes. Now think about this: The ultra-wealthy pay between 0% and 0.6% of their wealth in individual income tax – around 0.6% in a country like the United States and 0.1% in a country like France. We wrote about it in @lemonde.fr www.lemonde.fr/en/opinion/a...

An international call for action just got louder: Today, 7 Nobel Laureates have issued a powerful call for a minimum tax on the ultra-wealthy in Le Monde Here’s a quick breakdown of the debate—and where things stand globally 🧵 www.lemonde.fr/en/opinion/a...

Fewer reporting requirements had large negative effects on French wealth tax compliance, w/ 35% of wealth taxpayers missing in affected brackets & evading 10% of payments each year. @bgarbinti.bsky.social @s-stantcheva.bsky.social @gabrielzucman.bsky.social et al. cepr.org/voxeu/column... #EconSky

Quelle que soit la façon dont on regarde les choses, les milliardaires sont considérablement moins imposés que le reste de la population dans son ensemble Merci au Grand Continent de m’avoir permis de revenir sur cette réalité incontestable et inacceptable legrandcontinent.eu/fr/2025/07/0...

The G7 is exempting American multinationals from the global minimum tax. It’s pathetic and scandalous.

Predictable—and yet shameful and pathetic—capitulation of the G7, who agrees to let US multinationals escape the global minimum tax of 15% A clear illustration of why we need fundamentally new rules of the game www.nytimes.com/2025/06/27/b...

Après Olivier Blanchard et Jean Pisani-Ferry, Patrick Artus appelle à mettre en oeuvre la taxe Zucman. Le gouvernement dispose désormais : - de toute la caution intellectuelle nécessaire - d'une majorité à l'Assemblée Une situation rare ! www.alternatives-economiques.fr/patrick-artu...

New post: A minimum tax on billionaires mainlymacro.blogspot.com/2025/06/a-mi... The very rich pay a much lower percentage of their income in tax than almost everyone else. The 'Zucman tax' addresses this problem directly in a way designed to attract the maximum popular support.

Merci @lemonde.fr pour cet éditorial qui pose sereinement les termes du débat "L'équité fiscale passe par la taxation des ultrariches" 👇👇👇 www.lemonde.fr/idees/articl...

L’impôt plancher sur le patrimoine a été adopté par l’Assemblée nationale Il est plébiscité par les Français Sa logique économique est limpide Le Sénat, en première lecture, le rejette aujourd’hui Que fait on maintenant ? On continue ! 🧵

Pour que les Français acceptent la nécessaire consolidation des finances publiques, il faut que la charge en soit équitablement répartie. Ma tribune @lemonde avec O. Blanchard et G. Zucman. www.lemonde.fr/idees/articl...

Olivier Blanchard, Jean Pisani-Ferry et Gabriel Zucman : « Nous partageons le constat qu’un impôt plancher sur les grandes fortunes est le plus efficace face à l’inégalité fiscale »

Rendez-vous dimanche à #WeLoveGreen !

ah these countries where the head of state and oligarchs spend their time self-dealing or fighting for contracts, laws, and everything always revolves around this ... couldn't happen here, fortunately

Imagine if Latin American countries acted as one and said: "Our billionaires must pay their fair share" That's how global change starts So great to take part in the event hosted by @icrict.bsky.social Rumbo Colective & Oxfam at the Chilean Congress Library today—thanks for having me!

💥 “It sounds like we should tax billionaires…” A 2% minimum tax on the ultra-rich is the punchline with a plan: make them pay what ordinary people already do. With growing global momentum, this is no longer just theory. Read: www.ft.com/content/859e...

Zucman and co were proven exactly right—extreme wealth inequality makes democracy and the rule of law untenable. A global wealth tax is probably the most pro-democracy policy out there. www.ft.com/content/859e...

S'il y a référendum sur les finances publiques, il faudrait consulter les Français sur l'introduction d'un taux plancher d'imposition des ultra-riches (= possédant plus de 100 millions) Avec un taux de 2 %, c'est 20 milliards d'€/an 3%= 30 milliards / an www.lemonde.fr/politique/ar...

The total gutting of the IRS will have one main consequence: a surge in tax evasion by the wealthy Working-class and middle-class individuals don't evade a lot, because they can't High-income individuals do, because they can & because an industry helps them do it

C’est la petite musique qui monte : en ces temps de disette budgétaire il n’y aurait pas grand-chose à récupérer en s’attaquant à la fraude fiscale ; l’argent se trouverait plutôt du côté de la fraude sociale. Malheureusement cela ne repose sur rien. Petit état des savoirs sur le sujet 🧵

Come work with us!

Pour réaliser 40 milliards d’économie, le plus logique serait de commencer par fermer la niche fiscale « milliardaires » qui leur payer de payer 0 impôt sur le revenu ou presque, et qui a elle seule coûte de l’ordre de 20 milliards par an www.alternatives-economiques.fr/gabriel-zucm...
