Important Precautions and Practical Checklist to Safeguard Input Tax Credit (ITC)
In recent times, one major issue has rapidly emerged across the country – denial and reversal of Input Tax Credit (ITC) even in cases where purchases are genuine and tax has already been paid to the supplier.
A taxpayer purchases goods or services from a supplier, pays GST along with the invoice amount, makes payment through proper banking channels, and claims ITC in GSTR-3B. Despite this, GST authorities in many cases issue notices demanding reversal of ITC along with interest and penalty.
Today, such disputes are being raised on a large scale throughout India, particularly on the following grounds:
- Supplier failed to deposit GST with the Government
- Supplier failed to file GST returns
- Supplier’s GST registration was subsequently cancelled
- Allegation of fake billing or bogus firm
- Absence of E-Way Bill or transportation documents
- Invoice not reflecting in GSTR-2B
- Dispute under Section 16(2)(c) regarding payment of tax by supplier
The most concerning aspect is that in many cases:
- the purchases are genuine,
- goods/services are actually received, and
- payment has been made through banking channels,
yet the recipient taxpayer is still subjected to litigation and recovery proceedings.
In such a scenario, every GST taxpayer must strengthen documentation and compliance procedures from the very beginning. Proper due diligence and record maintenance can significantly help in defending the matter during departmental proceedings and appeals before higher authorities.
Important Checklist to Protect Your ITC
1. Obtain Proper Original Tax Invoice
Always obtain a proper GST Tax Invoice from the supplier.
If E-Invoicing is not applicable, ensure that the invoice contains:
- Rubber stamp/seal
- Authorized signature
- Complete firm details
The invoice should correctly mention:
- Supplier’s name and GSTIN
- Purchaser’s name and GSTIN
- Invoice number and date
- HSN/SAC Code
- Tax amount
- Place of supply
Incorrect or incomplete invoices may become grounds for denial of ITC.
2. Verify Supplier’s GST Registration Status
Search the supplier’s GSTIN on the GST Portal and ensure that:
- GST registration status is “Active”
- Registration is not suspended or cancelled
Keep screenshots or PDF copies of such verification for future records.
3. Verify Supplier’s Address from GST Portal
The address printed on the invoice should match with the principal place of business available on the GST Portal.
Mismatch in address may later lead to allegations that the supplier is non-existent or bogus.
4. Carefully Check Purchaser’s Details on Invoice
Ensure that the purchaser’s:
- Name
- GSTIN
- Address
are correctly mentioned on the invoice.
Even small clerical mistakes sometimes become grounds for litigation.
5. Verify HSN / SAC Code
The HSN/SAC Code mentioned in the invoice should correspond with the nature of business declared by the supplier on the GST Portal.
If the supplier issues invoices for goods/services unrelated to its declared business activities, the department may raise suspicion regarding genuineness of the transaction.
6. Prefer Payment Only After Invoice Reflects in GSTR-2B
Wherever practically possible, make payment to the supplier only after the invoice appears in your GSTR-2B.
This acts as preliminary evidence that the supplier has at least filed GSTR-1.
7. Verify Whether Supplier Has Filed GSTR-3B
Filing of GSTR-1 alone is not sufficient.
Also verify whether the supplier has filed GSTR-3B for the relevant tax period.
Nowadays, many businesses also obtain:
- GST compliance declarations
- Return filing confirmations
from suppliers periodically.
8. Maintain Copy of E-Way Bill (Where Applicable)
In transactions involving movement of goods, E-Way Bill is a very important document.
Maintain:
- E-Way Bill copy
- Vehicle details
- Transportation details
along with the invoice.
9. Preserve LR / GR / Transport Documents
Where goods are transported through transport agencies, maintain supporting records such as:
- LR Copy
- GR Copy
- Bilty
- Freight receipt
These documents help establish actual movement of goods.
10. Maintain Delivery Challans in Job Work Transactions
In case of job work transactions, preserve delivery challans relating to:
- Goods sent to job worker
- Goods received back from job worker
Further, ensure proper reporting in ITC-04 return wherever applicable.
11. Make Payment Only Through Banking Channels
Always make payment to suppliers through proper banking modes such as:
- Account Payee Cheque
- RTGS / NEFT
- UPI
- Bank transfer
Cash transactions may create unnecessary suspicion during assessment proceedings.
12. Ensure Payment Within 180 Days
Under Section 16(2) of the CGST Act, failure to make payment to the supplier within 180 days may trigger ITC reversal provisions.
Separate compliance requirements under MSME law should also be carefully followed wherever applicable.
Additional Important Precautions
13. Verify Supplier’s Business Credibility
Merely having an active GST registration is not always sufficient.
Wherever possible, verify:
- Business premises
- Market reputation
- Contact details
- Website / visiting card
- Banking details
before entering into substantial transactions.
14. Preserve Purchase Orders and Agreements
In major transactions, always maintain:
- Purchase orders
- Work orders
- Quotations
- Agreements
- Email communications
These documents help establish genuineness of the transaction.
15. Maintain Proof of Receipt of Goods
Where goods are received at warehouse or factory premises, preserve records such as:
- Goods inward register
- Stock register
- Weighment slips
- Gate entry register
These documents act as strong supporting evidence.
16. Conduct Regular Reconciliation
Regularly reconcile:
- GSTR-2B vs Purchase Register
- GSTR-1 vs GSTR-3B
- Books of accounts vs GST returns
Timely reconciliation helps identify discrepancies at an early stage.
17. Avoid Dealing with Suspicious Suppliers
Exercise caution while dealing with suppliers who:
- Offer unusually low billing margins
- Frequently change GST registrations
- Default in return filing
- Do not have proper business establishments
A cheap invoice today may result in expensive litigation tomorrow.
Can Buyer’s ITC Be Denied Solely Due to Supplier’s Default?
This is presently one of the most litigated issues under GST law.
Several High Courts have observed that where:
- purchases are genuine,
- goods/services are actually received,
- tax invoices are available,
- payment has been made through banking channels, and
- the buyer has exercised proper due diligence,
then ITC should not automatically be denied merely because the supplier failed to deposit tax with the Government.
However, every case depends upon its own facts and documentation. Therefore, stronger documentation substantially improves the taxpayer’s chances of succeeding in appeal proceedings.
Conclusion
Input Tax Credit is a valuable statutory right under GST law. However, under the present compliance environment, merely making genuine purchases is no longer sufficient.
Every taxpayer must now focus on:
- Proper documentation
- Supplier verification
- Compliance monitoring
- Banking trail
- Transportation evidence
The above checklist may appear time-consuming, but it can play a crucial role in protecting taxpayers from future tax demands, interest, penalties, and prolonged litigation.
Precaution and proper documentation are the strongest safeguards under GST law today.
