GST Input Tax Credit (ITC) is the mechanism that allows businesses to offset the GST paid on purchases (inputs) against the GST collected on sales (output tax). Proper ITC management — claiming every rupee you're entitled to while avoiding ineligible claims — directly impacts your working capital and compliance standing.
Critical: ITC on invoices for a financial year must be claimed by November 30 of the following year — after which it lapses permanently. Excess ITC already claimed and utilized but later reversed attracts interest at 24% per annum from the date of utilization. Always reconcile GSTR-2B monthly rather than at year-end to avoid large-scale reversals.
Match purchases to portal data
Every invoice in your purchase register must be matched against GSTR-2B (auto-populated from supplier filings). Unmatched invoices mean ITC is not yet available — we identify and resolve these monthly.
Section 17(5) ineligible ITC
Section 17(5) specifically blocks ITC on motor vehicles (for non-transport businesses), food/catering, club memberships, health/life insurance (non-mandated), and works contracts for immovable property. We screen all purchases for blocked categories.
Proportionate reversal under Rule 42/43
Businesses making both taxable and exempt supplies must reverse ITC proportionately under Rules 42 and 43. We calculate the reversal ratio accurately to minimize the reversal amount while ensuring compliance.
Chase defaulting suppliers
If a supplier hasn't filed GSTR-1, your ITC for their invoices is unavailable. We identify such suppliers monthly and support follow-up communications to protect your ITC.
All four conditions must be satisfied simultaneously to claim ITC on any purchase.
You must be a registered GST taxpayer. ITC cannot be claimed for periods before GST registration. Composition dealers and UIN holders (diplomats) are not eligible for ITC.
You must hold a valid GST invoice — with the supplier's GSTIN, your GSTIN (for B2B), HSN code, taxable value, and tax amount clearly mentioned.
The supplier must have filed their GSTR-1 and the invoice must appear in your GSTR-2B. ITC cannot be claimed for invoices not reflected in GSTR-2B — even if the invoice is genuine.
ITC is available only for goods and services used or intended to be used in the course of business for taxable supplies. Purchases for personal use, gifts, or exempt supplies do not qualify.
ITC directly affects your cash flow, tax liability, and working capital.
Every rupee of eligible ITC properly claimed reduces your net GST payment. For a business with ₹1 crore in GST-eligible purchases at 18%, that is ₹18 lakhs in tax savings annually.
ITC reduces the cash you need to deposit as GST each month — freeing working capital for business operations. Maximizing ITC reduces the need for GST cash deposits.
Excess ITC claimed attracts 24% per annum interest from the date of wrong utilization — significantly higher than the 18% rate on late payments. Correct ITC avoids this costly exposure.
Monthly GSTR-2B reconciliation identifies suppliers who are not filing returns — giving you visibility to switch to compliant vendors and protect your ITC chain.
Exporters and businesses in inverted duty structures (input tax rate > output tax rate) accumulate excess ITC that can be claimed as refund. We manage the complete refund application process.
ITC is the most frequently challenged item in GST audits and scrutiny. Documented reconciliation records provide a complete, verifiable audit trail that protects against demands.
ITC management is a monthly discipline — not a year-end exercise.
Scroll through the steps — or skip the queue and let our experts handle every one of them for you.
Get Expert HelpGather all supplier invoices for the month — including imports, interstate purchases, and reverse charge transactions. Organize by supplier GSTIN.
Filter out all Section 17(5) blocked items — motor vehicles, food, club memberships, personal insurance, works contract for real estate. These must never enter the ITC claim.
Download GSTR-2B from the GST portal and reconcile each purchase invoice against the auto-populated data. Identify unmatched invoices — where supplier has not yet filed.
If you make exempt or non-business supplies, calculate the ITC reversal under Rules 42/43 based on the proportion of exempt turnover to total turnover.
Enter the reconciled, eligible ITC in the appropriate tables of GSTR-3B — split by IGST, CGST, and SGST. Apply ITC in the correct order of utilization as per GST rules.
Maintain a running ITC register with opening balance, monthly claims, reversals, and closing balance — to support annual reconciliation in GSTR-9.
These records are essential for both claiming and defending ITC.
GST-compliant invoices from all suppliers — with GSTIN, HSN, taxable value, and GST amount.
Any CDNs received from suppliers affecting invoice values or ITC amounts.
For imports, the Bill of Entry issued by Customs — from which IGST paid on imports is claimed as ITC.
Under Rule 86B, businesses with taxable turnover above ₹50 lakhs in a month must pay at least 1% of their tax liability in cash (not ITC). This rule has exceptions — we identify whether Rule 86B applies to your business and plan accordingly.
ITC compliance is a continuous monthly process with annual reconciliation.
GSTR-2B is generated on the 14th of each month. Reconcile immediately against your purchase register — don't wait until the GSTR-3B deadline.
GSTR-9 requires a comprehensive reconciliation of ITC — claimed vs. available vs. reversed across all 12 months. Monthly discipline makes this exercise straightforward.
If your exempt-to-taxable revenue ratio changes during the year, the ITC reversal obligation changes too. Review and recalculate proportionate reversal at year-end.
Unclaimed ITC lapses permanently after November 30 of the following year, and reversed excess credit draws 24% annual interest. We reconcile GSTR-2B monthly so nothing is left on the table or clawed back later.
Credit matched against GSTR-2B every month instead of at year-end, catching gaps before they compound.
Input credit reviewed against invoices and business use to make sure nothing eligible goes unclaimed.
Ineligible or blocked credit flagged early so you never face the 24% interest on reversed ITC.
Vendor filing behaviour tracked, since a non-filing supplier can block your credit through no fault of your own.
