Does anyone have any experience with working a US job and trying to get a local DNI? It seems the most viable ways are to present a local Arg work contract or to show an income from US dividends over a certain amount to avoid paying double income tax on your US salary. Thanks!
You cannot "present a local Argentine work contract" if you are working (remotely) for a US company unless they are registered with AFIP to do business in Argentina.
If you are actually employed by a US company that is registered to do business in Argentina, you should be able to get temporary residency and a DNI with a "work contract" from your employer and also qualify for the foreign earned income exemption which is now more than $100K USD per year. If that's the case, you would only owe income tax in Argentina on income below the exemption and you would owe inome tax in the USA on income over it.
If you have passive US income from rental properties or stock dividends you may be able to qualify for the visa rentista and it may be possible to "avoid" Argentine income tax on that income if it is below the taxable threshold for income tax in Argentina (currently about $200K pesos per month?).
$200K pesos per month is vastly more than the current income requirement for the visa rentista, so, if you decide to go that route I suggest you carefully consider how much monthly income you "demonstate" to migraciones when applying for temporary residency.
In any case, you will have to qualify for some form of temporary residency before you will receive a DNI.
As always, others are welcome to add additonal information and/or corrections to this post
