The Income Tax (Payments on Account) Regulations 1996
Section 59A of the Taxes Management Act 1970 (inserted by section 192 of the Finance Act 1994) provides for a taxpayer to make payments on account of income tax as regards a year of assessment, if, as regards the immediately preceding year, the conditions set out in subsection (1) of that section are satisfied. Those conditions are that the taxpayer is assessed to income tax in any amount; that that amount (“the assessed amount”) exceeds the amount of income tax which has been deducted at source or otherwise treated as paid; that the amount of the excess (“the relevant amount”) is not less than such amount as may be prescribed; and that the proportion which “the relevant amount” bears to “the assessed amount” is not less than such proportion as may be prescribed.
