Our reading
It is the instrument that turns announcements into construction sites: every adhesion to the RIGI turns a filed project into a build, and every build opens up demand for suppliers and satellite services (R2 · the RIGI promise is kept). The whole portfolio shown below exists thanks to this scaffolding. And there is a door almost nobody uses: article 224 invites the provinces, the City of Buenos Aires and the municipalities to adhere, on the same footing — so a municipality can adhere even if its province has not. What the adhering jurisdiction gives up is set by article 225: no new local taxes may be imposed on the investor, measured against the line of 31-12-2023 (and raising a rate or narrowing an exemption on a tax that already existed also counts as new). Fees for services actually rendered can still be charged, with a ceiling: they may not exceed the cost of the service, and the text deems them to exceed it when they are calculated on sales, gross revenue or profits.
