Taxpayer received a notice from the "Large Business and INternational" division of the IRS a few months ago. The taxpayer is a nonresident alien who files a Schedule C for only the portion of her income earned in the US.
The taxpayer only has the first page of the letter which doesn't list an address, only a contact name and a phone number (area code 512). The listed agent doesn't return phone calls. (Her outgoing message says that calls will be returned in 3-5 business days.)
Does anybody know the address to which we can address correspondence?
Thanks for any help.
