How to claim input tax credit under GST
To claim ITC under GST you need a valid tax invoice, receipt of goods or services, and the supplier to have filed and paid the tax.
To claim input tax credit under GST, a business must have a valid tax invoice, have received the goods or services, and ensure the supplier has filed and paid the relevant GST.
What ITC means
Input tax credit (ITC) is the GST you paid on business purchases that you can set off against the GST you collect on sales. It stops tax from cascading at every step of the chain.
Example: You buy raw material with ₹1,000 GST and sell finished goods with ₹1,800 GST. If the purchase is eligible, you can use ₹1,000 as credit and pay ₹800 net (simplified illustration).
Basic conditions (in simple terms)
Rules have details and exceptions, but these are the everyday checks most MSMEs need:
- You are a registered taxpayer (and not blocked from ITC for that supply).
- You hold a valid tax invoice or debit note with required GST fields.
- You have received the goods or services.
- The supplier has reported the invoice and paid tax (reflected in your GSTR-2B / matching process as per current law).
- You use the goods/services for business (not purely personal), subject to blocked credit rules.
- You claim ITC in the correct return period within the allowed time limits.
Blocked credits (examples often include motor vehicles for personal use, certain food/entertainment costs, etc.) should not be claimed. When unsure, ask your CA.
Practical steps to claim ITC
- Save every purchase GST invoice — photo or PDF is fine; store it with the bill.
- Enter purchases in your books with GSTIN, taxable value, and tax split (CGST/SGST or IGST).
- Match with GSTR-2B (or your accountant’s reconciliation) so credit invoices appear.
- Claim eligible ITC while filing GSTR-3B for that period.
- Keep proof — invoices, e-way bills where relevant, and payment records for audits.
Common reasons ITC gets stuck
- Supplier delay in filing GSTR-1
- Wrong GSTIN or invoice number mismatch
- Claiming on a bill of supply (no tax charged) by mistake
- Claiming after the time limit for that financial year
- Personal or blocked expenses booked as business ITC
How clean records help
ITC is paperwork-heavy. If purchase bills are scattered across WhatsApp and paper files, month-end filing becomes slow and risky.
Billoxy stores organised, GST-compliant purchase and sale records so you can verify eligible credit and hand a clear trail to your accountant.
