- Refund of tax paid on inputs or input services used in making such zero-rated supplies made without payment of tax
- Refund of tax on the supply of goods regarded as deemed exports
- Refund of unutilized input tax credit, where the credit has accumulated on account of rate of tax on inputs being higher than the rate of tax on output supplies, except supplies of goods or services or both as may be notified by the Government on the recommendations of the Council
- Refund of tax paid on a supply which is not provided, either wholly or partially, and for which invoice has not been issued, or where a refund voucher has been issued

- The tax and interest, if any, or any other amount paid by the applicant, if he had not passed on the incidence of such tax and interest to any other person
