Guardian liability extends to payment and recovery of tax, interest or penalty when acting for an incapacitated person's business. Liability to pay tax, interest or penalty arises where a guardian, trustee or agent carries on a business for a minor or other incapacitated person; such liabilities shall be levied upon and recoverable from that guardian, trustee or agent in the same manner and to the same extent as if the incapacitated person were capacitated and conducting the business, and all provisions of the law and rules apply accordingly.
