i have some tax number here but i didn't update my address and they don't seem to really care over here in the atlantic, about what the idiots in lisbon think, which is quite comical (and the lady i dealt with was very friendly with me)
it's my firm opinion that you just play dumb, you stop interacting with the idiots in the bureaucracy, and you just build a strategy for how to deal with the possible, but not likely proactive investigation on your pitiful estate and it's lack of compliance with their extortion threats
it's not something that risk averse people will do, but i have much experience at various points in the systems i have interacted with, that tell me:
- they never really refund you anything
- they accept whatever idiot bullshit you provide to them
- it's better to not file anything
and lastly
- their whole business is criminal, and in violation of the constitution where you are, and/or the grandfathered in laws that still apply due to you living in a colony of whereever
