Turned out you can ride far not only despite it, but also thanks to it.
What is frustrating to me is the IRS was scammed. They sent my refund to some identity thief. This from an institution that if I owed them 10 cents, they could track down all of my financial accounts but they decide to deposit in some rando's account.
From what I can tell they claimed a lot of exemptions and got a refund.
How does that currently work?
In DK they just send it to your "nem konto", the same bank account that also gets your wages. More or less a sym link, so even if you move bank it will follow. Makes life easy.
if someone else can file for you they can put in whatever info they like, so.
if they think you're the target of identity theft they can step it up to requiring a PIN that they mail you?
Here in Denmark we have MitID, which you kind of use for everything. Taxes, every private banking login (you switch banks, keep the login), signing documents, all kinds of healthcare websites and apps, student loans and what not.
So instead the defacto ID is your SSN. This was never designed with that in mind, lacks all security mechanisms/checksums and all.
And if you were born before a certain time, all digits except the last few were determined by where you were born. And those last digits are the ones they frequently ask for...
This is all just choices guys.
