Subject to the provisions of this section, he is entitled at the end of each prescribed accounting period to credit for so much of his input tax as is allowable under section 26, and then to deduct that amount from any output tax that is due from him.

If either no output tax is due at the end of the period, or the amount of the credit exceeds that of the output tax then, subject to subsections (4) and (5) below, the amount of the credit or, as the case may be, the amount of the excess shall be paid to the taxable person by the Commissioners; and an amount which is due under this subsection is referred to in this Act as a “VAT credit”.

The whole or any part of the credit may, subject to and in accordance with regulations, be held over to be credited in and for a subsequent period; and the regulations may allow for it to be so held over either on the taxable person’s own application or in accordance with general or special directions given by the Commissioners from time to time.

Where at the end of any period a VAT credit is due to a taxable person who has failed to submit returns for any earlier period as required by this Act, the Commissioners may withhold payment of the credit until he has complied with that requirement.

A deduction under subsection (2) above and payment of a VAT credit shall not be made or paid except on a claim made in such manner and at such time as may be determined by or under regulations; and, in the case of a person who has made no taxable supplies in the period concerned or any previous period, payment of a VAT credit shall be made subject to such conditions (if any) as the Commissioners think fit to impose, including conditions as to repayment in specified circumstances.
