185.—(1) This regulation applies for the purpose of determining—
(a)the excess mentioned in section 59A(1) of TMA(1) (payments on account of income tax: income tax assessed exceeds amount deducted at source), and
(b)the difference mentioned in section 59B(1) of TMA(2) (payments of income tax and capital gains tax: difference between tax contained in self-assessment and aggregate of payments on account or deducted at source).
(2) For those purposes, the amount of income tax deducted at source under these Regulations is the total net tax deducted during the relevant tax year (“A”) after making any additions or subtractions required by paragraphs (3) to (5).
(3) Subtract from A any repayments of A which are made before the taxpayer’s return and self-assessment is made under section 8 or 8A of TMA(3) (personal return and trustee’s return).
(4) Add to A any overpayment of tax from a previous tax year, to the extent that it was taken into account in determining the taxpayer’s code for the relevant tax year.
(5) Add to A any tax treated as deducted, other than any direction tax, but—
(a)only if there would be an amount payable by the taxpayer under section 59B(1) of TMA on the assumption that there are no payments on account and no addition to A under this paragraph, and then
(b)only to a maximum of that amount.
