Il n'y a pas tant de bonnes nouvelles que ça alors réjouissons nous : 2 jours de conférence à l'Ecole d'économie de Paris ont montré que l'échange automatique d'informations fiscales, sans être parfait, a largement remis en cause les paradis fiscaux.

5/ We remain proudly hosted by @pse.bsky.social , benefiting from a world-class research environment alongside @wid.world, @ippofficial.bsky.social & #JPAL.
With a team of 35+ researchers & policy experts, we’ll continue to turn frontier research into actionable policy.
4/ We're honoured and happy that #EUTO, as lead of a European consortium, has been renewed and awarded the #TAXUD grant 🇪🇺🎉

3/ European projects remain a core pillar via EUTO, supported by the @ec.europa.eu 🇪🇺
Our goal: To be a central actor in research and action for more equitable and democratic societies🏛️⚖️
2/ Why the change? 🤔
Global challenges require global solutions. From our 2023 Global #TaxEvasionReport to G20 discussions on taxing ultra-high-net-worth individuals, our work has already crossed borders.
The ITO formalizes this global trajectory.
1/ Big news! Today, we officially launch the International Tax Observatory (#ITO)🚀
Building on the foundation of the EUTO, we are expanding our mission to address global tax evasion, wealth concentration, illicit financial flows & the intersection of taxation & the environment.
Wrapping up Day 2 with the closing keynote: "The AEOI – A Success Story?" by Pascal Saint-Amans.
💬 "Despite some gaps, the AEOI has been a success story. However, growing geopolitical fragmentation risks undermining the infrastructure on the ground that makes it work."
"In terms of challenges, the issue is twofold: the quality of CRS data and timing, as we hope to move toward real-time CRS reporting in the future." 💬 Diego Armando Miranda Barrios

"The challenge for Africa regarding #CRS is capacity building, which is why #ATAF is here to support countries in implementing AEOI. For African tax administrations, the most important thing is to use CRS data to conduct tax audits & increase tax revenues." 💬 Ezera Madzivanyika

"For developing countries, the #AEOI has improved taxpayer compliance, but non-compliance remains pervasive. Findings challenge the view that #LDCs with limited administrative capacity do not benefit from AEOI." 💬 Nadine Riedel

Day 2 kicks off with a session on Common Reporting Standard (CRS) & compliance.
"There is significant tax evasion through offshore tax havens, mostly driven by the wealthiest. Third-party information is key to tax enforcement, & AEoI contributes to this objective." 💬 @hjaltefb.bsky.social
"Data access has been difficult because these exchanges take place on the basis of a multilateral convention that has very strict confidentiality rules. Countries may consider information sharing a violation of the treaty and may stop sharing their information." 💬 Philip Kerfs

“The same mechanisms that operate for tax evasion are used for corruption. There is almost a perfect congruence/coincidence.” 💬 Matthew Caruana Galizia

"The real test for Africa is whether transparency leads to audits, tax collection, and changes in behavior. It is not the creation of new registries but the ability to use the existing ones effectively." 💬 Ezera Madzivanyika

Wrapping up Day 1 with a policy panel discussion on how far have we come along on the transparency road?
The experts are diving deep into the progress made and the challenges that lie ahead.
"Even without international reporting for #crypto, #Denmark 🇩🇰 enforces third-party reporting by domestic platforms. Linking these data to tax returns shows that about 90% of crypto sellers fail to report in a given year." 💬 Mona Baraké

"Crypto sits largely outside the traditional financial system, with no international third-party reporting. In Norway (2021), approximately 5% of adults owned crypto, but only 0.89% reported it for tax purposes—implying a reporting rate of about 17%." 💬 Andreas Okland

"Oligarchs’ companies have a very global footprint & rely heavily on tax havens. Sanctions have no impact on their global footprint. After sanctions are imposed, these companies tend to reallocate toward more secretive locations & continue to receive Western capital." 💬 Marcel Olbert

"Adopted in 2015, the EU’s 4th AML Directive required beneficial ownership registries. Exploiting its staggered adoption, evidence shows higher competition in public procurement, driven by open procurement procedures." 💬 Carol Seregni

Session 2: transparency & beneficial ownership
"Tax havens create negative spillovers—eroding tax bases & enabling crime. In 2015, #Ecuador 🇪🇨 imposed a +3pp corporate tax surcharge on firms owned via tax havens. Result: a 30% drop in observed haven ownership." 💬 @jakobbrounstein.bsky.social
"The Automatic Exchange of Information (AEOI) seems to deter the shifting of new wealth to offshore accounts; when people become wealthier after the AEOI, they are less likely to transfer money offshore." 💬 @gabrielzucman.bsky.social
