I have recently started working with a US based company. I am NOT a US citizen. I will be getting paid through PayPal. I would like to pay tax here as I am a permanent resident (married to an Argie) - have been here 7 years and might be here forever. How do i pay this tax here? I know i need to be registered as a monotributista but dont i need some kind of form from the company with my salary details etc?
