Reverse charge input tax credit: ITC timing follows the financial year of the recipient issued invoice, subject to tax payment. Where tax is payable by the recipient under the reverse charge mechanism for supplies from unregistered persons, the relevant financial year for the time limit to claim input tax credit is the financial year in which the recipient issues the invoice under the recipient invoice requirement, provided the recipient pays the tax and satisfies other conditions and restrictions; delayed issuance after time of supply attracts interest on late tax payment and possible penal consequences.
