Any section of this Act, including an amendment made by it to another Act, except paragraph 4 of section 263 and section 548, relating to the payment of taxes, or other amounts due, in several instalments to a municipal corporation, municipality or school board, has effect from the coming into force of the regulation contemplated in that paragraph 4.
The coming into effect of such a section does not entail a person’s obligation to pay a tax or an amount, payable before that coming into effect, on a shorter term or in greater instalments than under the provisions amended by such a section.
