Rule 89(4) and Rule 89(4B) under GST are important provisions for exporters who make zero-rated supplies without payment of IGST under a Letter of Undertaking (LUT) or Bond. These rules allow businesses to claim a refund of unused Input Tax Credit (ITC). As a result, exporters can reduce their working capital burden and improve cash flow. Furthermore, these provisions help ensure that exports remain free from unnecessary tax costs. Therefore, understanding Rule 89(4) and Rule 89(4B) under GST is essential for proper compliance and successful refund claims.
Key Points of Rule 89(4):
- Applicability:
It applies when goods or services are exported without payment of tax, and the exporter claims refund of unutilized ITC. - Refund Formula (As per Rule 89(4)):
Refund Amount = (Turnover of zero-rated supply of goods + Turnover of zero-rated supply of services) × Net ITC / Adjusted Total Turnover - Meaning of Key Terms:
- Net ITC: Input tax credit availed on inputs and input services during the relevant period (excluding capital goods).
- Turnover of zero-rated supply of goods: Value of export of goods made without payment of tax.
- Turnover of zero-rated supply of services: Value of export of services calculated as per GST rules.
- Adjusted Total Turnover: Total turnover in a State or Union Territory, excluding exempt supplies and turnover of supplies for which refund is claimed.
- Conditions:
- Exporter must have a valid LUT or Bond.
- Proper export documentation such as shipping bills and invoices must be maintained.
- Refund must be claimed within two years from the relevant date.
Key Points of Rule 89(4B):
- Purpose:
To prevent double benefits when exporters receive goods or services on which tax has already been paid. - Eligibility:
- Exporters making zero-rated supplies without payment of IGST under LUT or Bond.
- In addition, the refund applies only to unused ITC on inputs and input services used for exports.
- Restriction:
- If the supplier has already claimed a refund of tax paid on such supplies, the recipient cannot claim the same refund again.
- Ensures that refund benefits are not duplicated between supplier and recipient.
- Documents Required:
- LUT or Bond copy.
- Invoices for inputs and input services.
