Facebook is in a protracted battle with the IRS related to its off-shoring of IP to an Irish affiliate. Read more here. The IRS issued an administrative summons for the documents, and Facebook has refused to comply with the summons. The IRS is asking the court to enforce the summons and force Facebook to turn over the requested documents. The court agreed that on its face, the summons was issued for a legitimate purpose. Facebook will now have to tell the court why it refuses to turn over the documents. Review the court order here. Assumedly, Facebook is asserting that it is not required to disclose the requested materials based upon a claim of privilege. The case demonstrates that the IRS is aggressively seeking documents and information from taxpayers and their representatives in cases involving international tax issues.
