@VKNK , can you please either describe your issue or better start a new thread -- this is a very old thread ?
generally speaking the adjusted basis of foreign income often has a treaty component. Hence the need for a clear articulation of the issue --- what type of income, which country, are you a US person ( citizen/Green Card, Resident for Tax purposes ), if you are on a visa -- what type; are you in the USA or abroad etc. etc.---please
