Any person required to collect, truthfully account for, and pay over the tax imposed by this Act who willfully fails to collect such tax or truthfully account for and pay over such tax or willfully attempts in any manner to evade or defeat the tax or the payment thereof, shall, in addition to other penalties provided by law, be liable for the penalty imposed by Section 3-7 of the Uniform Penalty and Interest Act.

(e) Penalties assessable.

(1) In general. Except as otherwise provided in this Act or the Uniform Penalty and Interest Act, the penalties provided by this Act or by the Uniform Penalty and Interest Act shall be paid upon notice and demand and shall be assessed, collected, and paid in the same manner as taxes and any reference in this Act to the tax imposed by this Act shall be deemed also to refer to penalties provided by this Act or by the Uniform Penalty and Interest Act.
