(1) who aids or assists in, procures, or advises with respect to, the preparation or presentation of any portion of a return, affidavit, claim, or other document,Section 6701 may be viewed as the civil penalty analog to the tax crime of aiding and assisting, Section 7206(2), here.
(2) who knows (or has reason to believe) that such portion will be used in connection with any material matter arising under the internal revenue laws, and
(3) who knows that such portion (if so used) would result in an understatement of the liability for tax of another person.
One issue on the appeal was the appropriate burden of proof the Government must bear. Carlson argued that it was by clear and convincing evidence; the Government argued that it was by a preponderance. The Court held that the standard of proof is by clear and convincing evidence. Here is the Court's discussion:
I. The Government must prove violations of I.R.C. § 6701 by clear and convincing evidence.
At trial, the parties disputed the correct standard of proof. Carlson contends the correct standard should be clear and convincing evidence while the Government contends the correct standard is a preponderance of the evidence. The district court agreed with the Government and instructed the jury that the Government must prove its case by a preponderance of the evidence. We conclude that this instruction misstated the law.
Under the Eleventh Circuit's longstanding precedent, the Government must prove fraud in civil tax cases by clear and convincing evidence. See, e.g., Ballard v. Comm'r of Internal Revenue, 522 F.3d 1229, 1234 (11th Cir. 2008) ("The Commissioner has the burden of proving allegations of fraud by clear and convincing evidence."); Korecky v. Comm'r of Internal Revenue, 781 F.3d 1566, 1568 (11th Cir. 1986) ("The IRS bears the burden of proving fraud, which must be established by clear and convincing evidence."); Marsellus v. Comm'r of Internal Revenue, 544 F.2d 883, 885 (5th Cir. 1977) (holding fraud must be proved by clear and convincing evidence); Webb v. Comm'r of Internal Revenue, 394 F.2d 366, 378 (5th Cir. 1968) (same); Goldberg v. Comm'r of Internal Revenue, 239 F.3d 316, 320 (5th Cir. 1956) ("The Commissioner has the burden of proving fraud by clear and convincing evidence."); Jemison v. Comm'r of Internal Revenue, 45 F.2d 4, 5-6 (5th Cir. 1930) ("Fraud is not to be presumed, but must be determined from clear and convincing evidence, considering all the facts and circumstances of the case."). Our sister courts of appeals follow the same rule. See, e.g., Grossman v. Comm'r of Internal Revenue, 182 F.3d 275, 277 (4th Cir. 1999) (holding that a finding of fraud must be supported by clear and convincing evidence); Lessmann v. Comm'r of Internal Revenue, 327 F.2d 990, 993 (8th Cir. 1964) (same); Davis v. Comm'r of Internal Revenue, 184 F.2d 86, 86 (10th Cir. 1950) (same);Rogers v. Comm'r of Internal Revenue, 111 F.2d 987, 989 (6th Cir. 1940) ("Fraud cannot be lightly inferred, but must be established by clear and convincing proof."); Duffin v. Lucas, 55 F.2d 786, 798 (6th Cir. 1932) (same); Griffiths v. Comm'r of Internal Revenue, 50 F.2d 782, 786 (7th Cir. 1931) ("Fraud is never presumed but must be determined from clear and convincing evidence, considering all the facts and circumstances of the case.").
