Individual Taxpayer Identification Number Internal Revenue Service
If questions 11 through 17 on Form SS-4 do not apply to the applicant because he has no U.S. tax return filing requirement, such questions should be annotated "N/A". A foreign entity that completes Form SS-4 in the manner described above should be entered into IRS records as not having a filing requirement for any U.S. tax returns. Failure to respond to the IRS letter may result in a procedural assessment of tax by the IRS against the foreign entity.
