Retroactive clause for Italy + FICA taxes
Hi all,
I am an Italian Research Scholar (J1), first immigrated in the USA in November 2008. I claimed full income tax exemption under art. 20 and was FICA tax exempt for 2 calendar years. I have 2 questions for you:
1) I am extending my stay beyond 2 years. Does the Italy-USA tax treaty have a retroactive clause that will force me to give back income taxes? Could you append the official document supporting your answer?
2) I am a little bit puzzled by FICA taxes... I am sure I'll not retire in the US (indeed I am planning to go back to Europe in 1-2 years), so I am paying for a service I'll never take advantage from. Is there any way to claim these taxes back (or at least to legally stop paying them)?
Thanks in advance for your help!!
Francesco
