"Any tax assessable in accordance with Schedule 13 or 16 to [ICTA 1988] shall carry interest at the rate applicable undersection 178 of the Finance Act 1989 from the date when the tax becomes due and payable until payment."
"In a case where— (a) the company pays an amount of advance corporation tax in respect of qualifying distributions actually made by it in the relevant period, (b) the amount, or part of it, is available to be dealt with under this section, and (c) there is as regards the company an amount of notional foreign source advance corporation tax for the relevant period, an amount of the advance corporation tax paid shall be repaid to the company, or set off, or partly repaid and partly set off, in accordance with this section and section 246Q."
"No amount shall be repaid or set off under this section and section 246Q unless the company makes a claim for the purpose."
"If at the time when it falls to be determined whether the amount mentioned in subsection (1) above is to be repaid or set off— (a) advance corporation tax paid (or treated for the purposes of section 239 as paid) by the company in respect of distributions made by it in the relevant period has so far as possible been set against its liability to corporation tax for the period under section 239(1), but (b) the company's liability to corporation tax for the period is to any extent undischarged, the amount mentioned in subsection (1) above shall so far as possible be set off against the company's liability to corporation tax for the relevant period (and an amount of that liability equal to the amount so set off shall accordingly be discharged); and any excess of the amount mentioned in subsection (1) above over the amount so set off shall be repaid."
"No amount shall be repayable under section 246N and this section until the expiry of nine months from the end of the relevant period."
"I conclude that one cannot establish a set-off, whether at common law or equity it matters not, against an admitted liability, a right to repayment which can only arise once the admitted liability has been discharged. The two liabilities are not concurrent. The second liability is ultimately contingent upon the discharge of the first."
"The issue therefore is one of simple statutory construction. Can the expression 'payment' when used in section 87 of the 1970 Act, or 'pays' when used both in section 246N(2) of the 1988 Act and section 239 of the 1988 Act, encompass a set-off of the sort that the appellant asserts? In order to succeed, the appellant has to establish, both that those statutory references to payment or paying can potentially include a situation of set-off; and that also that in this case 'set-off' was in fact available to the appellant. In my judgment, the appellant fails on both of those scores."
"I am quite satisfied that, both in section 246N(2) and in section 87, 'payment' cannot extend to a set-off. First, it is the literal meaning of the statute that payment means payment, not to be departed from without good reason. Secondly, the statute itself distinguishes payment from set-off. It does so in terms in section 246N(2), and the judge drew attention to that, if I may say so rightly, when she said this: 'Part of the pattern of the Act is to use words "paid" and "repaid" in circumstances which do not sit comfortably with the concept of set-off. It is interesting also to note that where it regards it as appropriate, the statute does, indeed, refer to set-off and one sees those words in section 246N(2) itself.' Third, there is a clear policy reason, in the interests of the Revenue's cash flow, why advance corporation tax must be actually paid, and not treated as a suspended book debt which the taxpayer can revert to or fall back on when his corporation tax comes to be assessed. The judge so found: 'It is plain that advance corporation tax is designed to define and instigate an income stream to be paid in to the Revenue in advance of the corporation tax assessment.' That, I think, is not a controversial point, but it is valuable to see it as the basis of the judge's approach to this subject. It points very strongly against any suggestion that a taxpayer can be counted as having 'paid' advance corporation tax when he has paid nothing at all. Fourthly, the very outline account that I have ventured to give of the background to the law of set-off indicates that, on any view, it is something very different from, much more complicated than, and much more many-headed than the single concept of payment. It would be odd indeed if the legislature had imported the concept of set-off into a statute without making it plain what aspect of set-off it was referring to, and even more difficult to know, against the background that I have set out, exactly what it is that counts as a set-off that can be relied on as equivalent to statutory payment."
"[20] … had it paid its advance corporation tax as the statute required, in January, none of this trouble would have occurred and we would not have had to spend time investigating what I have to say are arcane matters of equitable law. [21] This system is simple and straightforward. Taxpayers may not like it but it is what Parliament has decided. If people keep the rules everybody knows where they are. The rules were not kept in this case."
