The Income Tax (Payments on Account)(Amendment) Regulations 1997
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; andthat the proportion which the relevant amount bears to the assessed amount is not less than such proportion as may be prescribed.
