Any amount which a person is required to pay by a secondary-liability notice may be recovered from the person as if it were tax due and duly demanded from the person.
If a person ("H") pays any amount which a secondary-liability notice requires H to pay, H may recover the amount from the person on whom the assessment concerned was made.
A payment in pursuance of a secondary-liability notice is not allowed as a deduction in calculating any income, profits or losses for any tax purposes.
