I am employed in the US but not a US citizen. My wife, who is not a US citizen either and has never been in States, will join me soon. She has sold our property abroad and would like to transfer the moneys by sending it as a wire transfer from her account overseas to mine in the US. Assuming the amount is between US $100K-$150K in order to buy a property in the USA, what would be my IRS Tax filing/declaration requirements if any? Would I have to actually pay any taxes?
