Top 10 Errors Detected During a GST Health Checkup
In today’s regulatory environment, staying GST-compliant is not a choice — it’s a necessity. A GST Health Checkup is like a financial diagnostic test that uncovers compliance gaps, reporting mismatches, and tax inefficiencies in your GST filings.
At YKG Global, we’ve conducted GST Health Checkups for companies across industries. Through our experience, we’ve identified some recurring errors that could lead to serious consequences — including interest, penalties, and even departmental audits.
Let’s uncover the Top 10 most common errors detected during a GST Health Checkup so you can stay ahead of compliance risks.
1. Mismatch Between GSTR-3B and GSTR-1
One of the most frequent errors is the difference in outward supply data reported in GSTR-1 and GSTR-3B. This mismatch can trigger scrutiny notices or rejection of ITC by the department.
Pro Tip by YKG Global: Reconcile GSTR-1 with GSTR-3B monthly, not just at year-end.
2. Ineligible Input Tax Credit (ITC) Claimed
Many businesses wrongly avail ITC on ineligible expenses such as personal use items, blocked credits under Section 17(5), or invoices older than one year.
Tip: Always match ITC with vendor data from GSTR-2B.
3. Non-Reversal of ITC on Exempt or Non-Business Use
As per Rule 42 & 43 of CGST Rules, partial ITC reversal is mandatory when inputs are used for both taxable and exempt supplies. This is often overlooked.
Impact: Department may demand ITC reversal with interest.
4. Delay in Tax Payments or Filing Returns
Late filing of GSTR-3B or GSTR-1 attracts late fees and interest — and it affects the GST rating of the company.
YKG Insight: A good compliance rating builds trust with stakeholders and vendors.
5. Errors in HSN Code Declaration
Wrong HSN/SAC codes lead to classification errors, causing wrong tax rates and departmental queries.
Tip: Use the latest HSN codes as per turnover threshold.
6. Undisclosed or Missed Outward Supplies
Businesses often miss reporting:
6.1 Branch transfers
6.2 Free samples
6.3 Reimbursements
All of these are reportable under GST.
7. Wrong Place of Supply
Inaccurate place of supply determination can result in wrong GST type (CGST/SGST vs. IGST), leading to credit mismatches and interest demands.
8. Not Reconciling Books with GST Returns
Discrepancy between financial books and GST returns creates compliance red flags.
YKG Global Tip: Monthly reconciliation helps avoid year-end surprises.
9. Not Reporting Advances and Reverse Charge Liabilities
Many companies skip:
9.1 Advance receipts
9.2 Reverse charge payments (especially on import of services or rent)
9.3 This non-disclosure could lead to short payment notices.
10. Missing or Expired E-Invoice Requirements
If you're mandated to issue e-invoices and fail to do so, your invoice becomes invalid under GST law.
Important: Check your e-invoice applicability based on turnover each financial year.
