Input Tax Credit (ITC) under GST: Conditions to Claim, Blocked Credits and Time Limit
Input tax credit lowers your GST bill, but only if you meet the conditions. Here is what must be true, what is blocked and when you must claim.
Input tax credit (ITC) is the engine of GST. It lets a business reduce the GST it pays to the government by the GST it already paid on purchases used for business. Claim it correctly and your tax cost drops; claim it wrongly and you face reversal, interest and notices.
The basic conditions to claim ITC
Section 16 of the CGST Act sets the core conditions. In plain terms, you must:
- Hold a valid tax invoice or other prescribed document from the supplier.
- Have actually received the goods or services.
- Ensure the invoice appears in your GSTR-2B, meaning the supplier has reported it.
- Ensure the supplier has actually paid the tax to the government.
- File your return (GSTR-3B) in which the credit is claimed.
If you do not pay your supplier within 180 days of the invoice date, the credit must generally be reversed with interest, and can be re-claimed once you pay.
Why GSTR-2B matching is critical
GSTR-2B is the auto-drafted ITC statement that the GST system generates for you each month. Claiming ITC that does not appear in it is a common trigger for notices. Reconcile your purchase books with GSTR-2B every month, before you file GSTR-3B.
Blocked credits under Section 17(5)
Some credits are not allowed even if you hold a valid invoice. Common examples include:
- Motor vehicles for passenger transport, with specific exceptions (for example, when used for further supply or for transport of goods).
- Food, beverages, outdoor catering, club membership, health and fitness services, and similar personal-consumption items, with limited exceptions.
- Goods or services used to construct immovable property (other than plant and machinery), for the business’s own account.
- Goods lost, stolen, destroyed or given as free samples or gifts.
Time limit to claim
ITC for an invoice of a financial year can be claimed up to 30 November following the end of that year, or the date of filing the annual return for that year, whichever is earlier. Missing this deadline means losing the credit, so build a year-end check into your routine.
A simple monthly ITC routine
- Download GSTR-2B after the 14th.
- Match it with your purchase register.
- Follow up with suppliers whose invoices are missing.
- Claim only eligible credit in GSTR-3B and reverse what is ineligible.
Frequently asked questions
Can I claim ITC on an invoice that is not in GSTR-2B?
Not safely. The law ties the claim to the invoice being reported by the supplier, so keep such credit on hold until it shows up.
Is ITC available on capital goods?
Yes, subject to the same conditions, and not if you depreciate the GST portion for income-tax purposes.
What if my supplier never files?
Pursue the supplier, as the credit may be denied. Keep records of your communication and payment.
