IRS Form W8
W-8s for U.S. Citizens Abroad: Filing False Information with Non-U.S. Banks
Individuals who do not specialize in U.S. federal tax law, often have little detailed understanding of the U.S. federal “Chapter 3” (long-standing law regarding withholding taxes on non-resident aliens and foreign corporations and foreign trusts) and “Chapter 4” (the relatively new withholding tax regime known as the “Foreign Account Tax 
Compliance Act”) rules.
Indeed, plenty of U.S. tax law professionals (CPAs, tax attorneys and enrolled agents) do not understand well the interplay between these two different withholding regimes –
- 26 U.S. Code Chapter 3 – WITHHOLDING OF TAX ON NONRESIDENT ALIENS AND FOREIGN CORPORATIONS
- 26 U.S. Code Chapter 4 – TAXES TO ENFORCE REPORTING ON CERTAIN FOREIGN ACCOUNTS
Plus, the IRS forms have been significantly modified over the years; with increasing factual representations that must be made by individuals who sign the forms under penalty of perjury. They are complex and not well understood. For instance, the older 2006 IRS Form W-8BEN for companies was one page in length and required relatively little information be provided.
The entire form is reproduced here; indicating how foreign taxpayer information was optional and generally there was no requirement to obtain a U.S. taxpayer identification number. It was governed exclusively by Chapter 3 and the regulations that had been 
extensively produced back in the early 2000s.
The forms were even easier before those regulations (see old IRS Form 1001). No taxpayer identification numbers were ever required and virtually no supporting information regarding reduced tax treaty rates on U.S. sources of income.
Life was simple back then – compared to today!
The one thing all of these forms have in common is that all information was provided and certified under penalty of perjury. Current day IRS Forms W-8s can typically be completed accurately by experts who understand the complex web of rules. Plus, multiple versions of W-8s exist today; most running some 8+ pages in length.
See the potpourri of current day W-8 forms –
Making certifications under penalty of perjury are more complex, the more and more factual information that is being certified. If I certify the dog I see in front of me is “white and black” that is not a complex certification, if I see the dog and see the “white and black”. If the dog also has some brown coloring, my certification would necessarily not be false.
However, if I have to certify as to the colors of each dog in a pack of 8 dogs (and each and every color that each dog is/was), that becomes a much more complicated certification.
That’s my analogy for the old IRS Forms W-8s and the current day IRS Forms W-8s.
Compare that form, of just 10 years ago, with what is required and must be certified to under current law. It can be daunting.
Now to the rub. Individuals who certify erroneously or falsely, can run a risk that the government asserts such signed certification was done intentionally. I have seen it happen in real cases; even though the individual layperson (particularly those who speak little to no English and live outside the U.S.) typically has little understanding of these rules. They typically sign the documents presented to them by the third party; usually the banks and other financial institutions.
The U.S. federal tax law has a specific crime, for making a false statement or signing a false tax return or other document – which is known as the perjury statute (IRC Section 7206(1)). This is a criminal statute, not civil. Some people are also under the misunderstanding that a false tax return needs to be filed. The statute is much broader and includes “. . . any statement . . . or other document . . . “.
(1) Declaration under penalties of perjury
Willfully makes and subscribes any return, statement, or other document, which contains or is verified by a written declaration that it is made under the penalties of perjury, and which he does not believe to be true and correct as to every material matter; or . . .
Therefore, if a U.S. citizen living overseas (or anywhere) signs IRS Form W-8BEN (or the bank’s substitute form, which requests the same basic information), that signature under penalty of perjury will necessarily be a false statement, as a matter of law. Why? By definition, the statute says a U.S. citizen is a “United States person” as that technical term is defined in IRC Section 7701(a)(30)(A). Accordingly, IRS Form W-8BEN, must only be signed by an individual who is NOT a “United States person”; who necessarily cannot be a United States citizen. To repeat, a United States citizen is included in the definition of a “United States person.” Plus, the form itself, as highlighted at the beginning of the form, warns against any U.S. citizen signing such form. 
Accordingly, if a U.S. citizen were to sign IRS Form W-8BEN which I have seen banks erroneously request of their clients, they run the risk that the U.S. federal government will argue that such signatures and filing of false information with the bank was intentional and therefore criminal under IRC Section 7206(1). See a prior post, What could be the focal point of IRS Criminal Investigations of Former U.S. Citizens and Lawful Permanent Residents?
Indeed, criminal cases are not simple, and I am not aware of any single criminal case that hinged exclusively on a false IRS Form W-8BEN. However, I have seen cases, where the government has alleged the U.S. born individual must have signed the form intentionally, knowing the information was false. It’s a question of proof and of course U.S. citizens wherever they reside, should take care to never sign an IRS Form W-8BEN as an individual certifying they are not a “United States person”; even if they think they are not a U.S. person
