Common GST Refund Mistakes to Avoid

The Goods and Services Tax (GST) framework was introduced to simplify India’s indirect tax system and ensure transparency. However, while the GST refund mechanism aims to ease working capital pressures for businesses, many taxpayers still face refund rejections or delays due to avoidable mistakes. Understanding and avoiding these common errors can help Delhi-based taxpayers ensure faster and smoother GST refund processing.

Incorrect or Incomplete Documentation

One of the most frequent reasons for refund rejection under GST is incomplete or incorrect documentation. Businesses often miss attaching key supporting documents such as invoices, bank realization certificates (BRCs), or shipping bills while filing the refund application in FORM GST RFD-01.

How to Avoid It

• Maintain proper invoice records and reconcile them monthly.
• Ensure all documents are uploaded in the correct format and within the prescribed limit.
• Cross-verify details before final submission to avoid mismatches.

Under Delhi GST law, refund applications must comply with both CGST and SGST provisions, so missing even one state-level requirement may lead to delays.

Mismatch Between GSTR-1, GSTR-3B, and Books of Accounts

The GST system heavily relies on automated reconciliation. A mismatch between the details declared in GSTR-1, GSTR-3B, and your accounting records is a red flag for tax authorities. Even a small discrepancy can trigger scrutiny or rejection.

How to Avoid It

• Perform a monthly reconciliation of outward supplies and tax payments.
• Rectify errors before filing returns.
• Use a GST compliance service or software to automate reconciliation and reduce manual errors.

Businesses in Delhi often face mismatches due to multiple state branches or input service distributors (ISDs). Regular internal checks help maintain accuracy and compliance.

Delay in Filing Refund Application

As per Rule 90 of the CGST Rules, 2017, the refund application must be filed within two years from the relevant date. Many taxpayers miss this timeline, leading to loss of eligible refunds.

How to Avoid It

• Track refund timelines in your compliance calendar.
• Prioritize high-value refund cases (like exports or inverted duty structure).
• Engage professional GST refund services in Delhi for end-to-end support and timely submission.

In Delhi, GST authorities strictly adhere to statutory timelines, so delayed filings are rarely entertained.

Wrong Category Selection in Refund Application

While filing refund claims in FORM GST RFD-01, taxpayers must select the correct category—such as refund of excess cash balance, export without payment of tax, or inverted duty structure. Many businesses choose the wrong category, leading to rejection.

How to Avoid It

• Understand refund types as defined in Section 54 of the CGST Act.
• Seek professional advice before submission.
• If an error occurs, withdraw and reapply under the correct category promptly.

Correct categorization ensures faster processing by Delhi’s GST department and minimizes correspondence delays.

Ignoring the Rule of Unjust Enrichment

The doctrine of unjust enrichment prevents taxpayers from claiming a refund that they have already passed on to customers. Failing to submit a CA certificate or declaration under this rule often leads to rejection.

How to Avoid It

• Attach a Chartered Accountant’s certificate confirming that the refund amount has not been passed on.
• Maintain transparent accounting and documentation to support refund claims.

Delhi authorities strictly verify unjust enrichment declarations, especially for large-value claims.

Incorrect Input Tax Credit (ITC) Claims

Claiming ineligible Input Tax Credit (ITC) or misclassifying zero-rated supplies is another major cause of refund disallowance. Errors often arise due to confusion between input goods and input services or inter-state and intra-state transactions.

How to Avoid It

• Verify ITC eligibility under Section 16 of the CGST Act.
• Keep track of blocked credits listed under Section 17(5).
• Use professional GST compliance services to monitor ITC utilization accurately.

Proper ITC management ensures that refund applications withstand scrutiny by Delhi’s GST officers.

Lack of Consistency in Export and Bank Records

For exporters and zero-rated suppliers, refund claims often fail due to mismatches between shipping data, invoices, and bank realization details. The GST portal cross-verifies this data with ICEGATE (Customs portal).

How to Avoid It

• Ensure that shipping bills and export invoices match the GST returns.
• Maintain clear documentation of foreign inward remittance certificates (FIRCs).
• Regularly reconcile export data with bank records.

In Delhi, exporters must coordinate with both GST and Customs authorities to ensure seamless refund approvals.

Not Responding to GST Notices on Time

After filing a refund, taxpayers may receive queries or deficiency memos from the GST officer. Ignoring these communications can lead to automatic rejection.

How to Avoid It

• Regularly check your GST portal for notices under FORM GST RFD-03 or RFD-08.
• Respond promptly and submit required clarifications within the prescribed time.
• Maintain communication logs for compliance records.

Timely response demonstrates transparency and builds credibility with Delhi’s GST authorities.

Inadequate Record Keeping

Maintaining GST-related records for at least six years is mandatory under Section 36 of the CGST Act. Missing records during audits or refund verifications can lead to disputes or recovery proceedings.

How to Avoid It

• Digitally archive invoices, returns, and refund applications.
• Conduct annual audits to ensure all records are up-to-date.
• Use cloud-based GST filing and record management tools.

Strong record-keeping practices safeguard businesses during departmental scrutiny.

Not Taking Professional Assistance

Many businesses attempt to handle refunds in-house, but given the complexity of Delhi’s GST environment, expert assistance can make a significant difference. Professionals specializing in GST refund services ensure compliance, accuracy, and timely processing.

Why It Matters

• Experts are well-versed in the latest GST notifications and Delhi-specific updates.
• They help minimize errors and handle departmental communication effectively.
• Their structured approach reduces refund rejections and financial stress.

Conclusion

Avoiding these common GST refund mistakes can save Delhi taxpayers valuable time and money. With proper documentation, timely filing, and professional support, your refund claim can move smoothly through the verification process.

If you’re a Delhi-based business seeking reliable guidance on GST refunds, consider consulting qualified tax professionals who can manage your refund process efficiently and ensure compliance with both Central and Delhi GST laws.
