How to File a GST Refund for an Inverted Duty Structure

The Goods and Services Tax (GST) system in India has streamlined indirect taxation and improved transparency. However, certain industries or businesses that deal with an inverted duty structure often face a challenge they pay more tax on inputs than they collect on output sales. To address this imbalance, the government allows businesses to claim a GST refund for an inverted duty structure.

This article explores how to file such a refund, the steps involved, its benefits, eligibility criteria, and FAQs, especially with a focus on using the GST refund portal.

Why is a GST Refund Necessary for Inverted Duty Structure?

An inverted duty structure arises when the GST rate on inputs (raw materials or input services) is higher than the GST rate on output supplies (final goods or services). This results in accumulation of unutilized Input Tax Credit (ITC) in a business’s electronic credit ledger.

Without refunds, this excess credit remains locked, negatively impacting cash flow and working capital. Hence, the GST law provides a mechanism for refund of the unutilized ITC to help maintain financial stability and operational efficiency.

Advantages of Filing a GST Refund under Inverted Duty Structure

1. Improved Cash Flow: Unlocking blocked ITC helps maintain liquidity for business operations.
2. Compliance Recognition: Businesses claiming refunds regularly are seen as compliant and eligible for other tax benefits.
3. Operational Efficiency: Reduces the burden of input costs over time.
4. Financial Planning: Provides a clear projection of available funds and tax planning.
5. Encouragement for Exporters: Export-oriented businesses often face inverted duty structures and benefit from refund mechanisms.

Eligibility for GST Refund under Inverted Duty Structure

Businesses are eligible for a GST refund in an inverted duty structure scenario if:

• They deal in goods/services where input GST is higher than output GST.
• They are not availing refund under zero-rated supplies (like exports) simultaneously for the same tax period.
• The inverted duty structure refund claim is not barred by notification (some goods are restricted).
• The refund is claimed within two years from the end of the relevant tax period.

Important Note: Certain items like coal, petrol, or services where inversion does not exist are excluded from refund eligibility.
