HC Deb 17 November 1986 vol 105 c80W
Mr. Stern

asked the Chancellor of the Exchequer whether, in view of the fact that the new form of income tax assessment incorporates a demand note in the form of a bank giro credit, it is the intention of the Inland Revenue to treat the tax as paid when it is paid into the payer's bank, or when the amount of tax is received by the collector of taxes.

Mr. Norman Lamont

Where a taxpayer makes a payment of tax at a branch bank using the bank giro system, the Inland Revenue treats the date stamped on the payslip by the bank cashier as the date of payment.
