No, I am saying that it is NOT the bank's responsibility to question the legality of a levy from the IRS. It is the taxpayer's responsibility to do that. If a levy is served to the bank, the bank must comply, as required by law.
The taxpayer cannot prevent the bank from complying with the levy. The only way to stop or remove a levy is through contact with the IRS. If you feel the IRS is in error, and you are getting nowhere with them, I advise you to contact the office of the Taxpayer Advocate, whose job it is to work out these sorts of things if the IRS is being improper.
It works the same way if your employer is served a notice to levy your wages. The employer is required to comply, and is not in a position to question whether the levy is legal or not. It isn't relevant, either to the bank or to the employer.
