“The wording of regulation 13(3) also precludes the making of a direction under regulation 9 after the date on which a determination has been made. It seems to us that the intention is that regulation 9 and regulation 13 are mutually exclusive. If an amount is included in a direction made under regulation 9(5) it cannot be included in a subsequent determination under regulation 13, but if an amount is included in a determination under regulation 13, it cannot thereafter be the subject of a direction under regulation 9.”
“52. I turn to the question of double taxation and double recovery. I return to CISR §83050 (see §39iv above), inserting square brackets for referencing purposes: [a] The purpose of directions under Regulation 9(5) is to avoid the situation where HMRC pursues a contractor for a deduction that should have been made where the subcontractor has no liability, or has already met any tax liability, on the sum paid gross. [b] It follows the principle that HMRC should not recover more tax from both contractor and subcontractor than is correctly payable by the subcontractor. That is why the relief is sometimes known as ‘double taxation’ relief. [c] A request for a direction under Regulation 9(5) may be made at any time except where a Determination under regulation 13(2) has already been issued (see CISR83040) ... This involves a recognition (at [a]) that a Non-Liability Direction on the Chargeability- Basis or the Collection-Basis is a form of “relief” whose “purpose” is to “avoid the situation” where the Contractor is pursued for failure to make a Contract Payment deduction where the Sub-Contractor “has no liability, or has already met any tax liability, on the sum paid gross”
