There seems little doubt that the "vibe" is exactly as you say: to "penalize" argentines who had moved funds outside the country.
But where is the evidence that the executive and the AFIP will so helpfully interpret it now (and in the future) in accordance with the vibe?
It's a genuine question. Any evidence from AFIP's past behaviour (or any equivalent agency elsewhere in Latin America--my own personal experience has been in Peru, where vibes have not been helpful in dealing with the tax authority; someone commenting above also has given the impression that in Colombia one ought to take notice of what the legislation says rather than its vibe) would be very welcome and helpful at this point of the debate.
Well, we are in Argentina and ANYTHING can happen. I am the last person anyone should listen to. I am just a random dude on an expat forum.
Not a tax lawyer nor an accountant. I am just trying to be logical and play a devil's advocate. If you read some US tax laws you will find out they’re equally if not more vague, and it's ultimately the IRS that interprets it. A “resident for tax purposes” there is a very specific term that does NOT overlap with “immigration residency”.
This law was passed in 48hs! The reason why they moved from "domiciliado" to "residente" in Argentina, is to close a loophole that some people used to claim they live abroad.
Here’s the problem with taking a NARROW interpretation of the “residency” term.
1. As a “temporary resident” you de facto declare you are domiciled here in Argentina throughout your residency and when you apply for an extension with MIGRACIONES or change of category to permanente this is also the case. The law on bienes personals has existed for many years before this amendment. So basically, if we follow this narrow view THEN ALL of us temporary or permanent residents should have paid 0.25% (the old rate) on all assets here or abroad every prior year because the law relied on “domicile” concept and when you sign your “declaracion jurada” at migraciones you de facto claim domicilio here.
2. Additionally, Argentine law considers tourists residents as well. They are residents transitorios. So if you are here as a tourist for say 6 months and 1 day are you supposed to pay this tax? Of course not.
