Common use of Declarations of estimated tax Clause in Contracts

Declarations of estimated tax. In the case of a taxable year beginning before the date of the enactment of this Act, if any taxpayer is required to make a declaration or amended declaration of estimated tax, or to pay any amount or additional amount of estimated tax, by reason of the amendments made by this Act, such amount or additional amount shall be paid ratably on or before each of the remaining installment dates for the taxable year beginning with the first installment date on or after the 30th day after such date of enactment. With respect to any declara- tion or payment of estimated tax before such first installment date, sections 6015, 6154, 6654, and 6655 of the Internal Revenue Code of 1954 shall be applied without regard to the amendments made by this Act. For purposes of this subsection, the term ‘‘installment date’’ means any date on which, under sec- tion 6153 or 6154 of such Code (whichever is applicable), an installment payment of esti- mated tax is required to be made by the tax- payer.
