RS 47:337.73: Negligence penalty

If any taxpayer fails to make any return required by this Chapter or makes an incorrect return, and the circumstances indicate willful negligence or intentional disregard of rules and regulations, but no intent to defraud, there shall be imposed, in addition to any other penalties provided, a specific penalty. This specific penalty shall be an obligation to be collected and accounted for in the same manner as if it were a part of the tax due, and can be enforced either in a separate action or in the same action for the collection of the tax.
