Bottom Line

Running a business in Delhi NCR comes with unique compliance challenges, especially when dealing with GST refunds. Many businesses in the region face delays, rejection, or partial refunds due to common mistakes that can be easily avoided. If you're struggling with GST refund issues in Delhi NCR, understanding these problems and their solutions can help you recover your money faster.

Problem 1: Incorrect LUT (Letter of Undertaking) Filing

Exporters and businesses providing services outside India often forget to file LUT before starting export supplies. Without valid LUT, you must charge IGST on exports and wait for refund later, which delays your cash flow.

Solution:

File LUT on GST portal before first export

LUT is valid for 3 years

Renew promptly if expired

Mark export invoices as "Export under LUT"

Problem 2: ITC Mismatch with GSTR-2B

Many businesses claim input tax credit (ITC) that doesn't match their GSTR-2B. The GST portal automatically rejects ITC not available in GSTR-2B, leading to refund rejection.

Solution:

Download GSTR-2B monthly (available from 14th)

Verify ITC before claiming in GSTR-3B

Match ITC with supplier's GSTR-1

Reconcile monthly to avoid surprises

Problem 3: Delayed Refund Application

Businesses often file refund application (Form RFD-01) after the 2-year deadline from relevant date. Late applications are automatically rejected by the system.

Solution:

File refund within 2 years from relevant date

Set calendar reminders for refund deadlines

Prepare documents early

Submit application before deadline

Problem 4: Incomplete Documentation

Refund applications without proper supporting documents like export invoices, shipping bills, bank proof, or LUT copy are rejected or delayed for verification.

Solution:

Prepare document checklist before filing

Include all mandatory documents

Keep digital and physical copies

Verify document completeness before submission

Problem 5: Wrong Refund Category Selection

Selecting wrong refund category (e.g., choosing "ITC refund" instead of "Export refund") leads to application rejection or incorrect refund amount.

Solution:

Understand refund categories clearly

Select correct category based on your case

Consult GST expert if unsure

Verify selection before submission
