Input tax credit lets you reduce your GST liability by claiming the tax you already paid on purchases. Here is the complete guide to ITC rules, eligibility, and the claiming process after GST 2.0.
Input Tax Credit is the mechanism that prevents the cascading effect of taxes — the tax-on-tax problem that existed before GST. When you buy raw materials, services, or capital goods for your business, you pay GST on those purchases. ITC lets you deduct this GST paid on inputs from the GST you collect on your sales. You only pay the government the difference.
Example: You buy fabric for Rs 10,000 + 5% GST (Rs 500). You make shirts and sell them for Rs 20,000 + 5% GST (Rs 1,000). Without ITC, you pay Rs 1,000 to the government. With ITC, you deduct the Rs 500 you already paid on fabric. You pay only Rs 500 (Rs 1,000 - Rs 500). This is how GST avoids double taxation.
After the GST 2.0 reform in September 2025, the ITC mechanism remains the same but the rates changed. Items that moved from 12% to 5% mean less ITC available on those inputs. Items that moved from 28% to 18% mean less ITC but also less output tax. The net impact depends on your specific business — we explain the details below.
myBillPlease tracks ITC automatically. When you record purchase invoices, the GST amount flows into your GSTR-3B report as input credit. Your net tax payable calculates automatically. Start free — no credit card needed.
Section 16 of CGST Act specifies 4 conditions — all must be met
Section 17(5) of CGST Act lists items where ITC is not available even if you have a valid invoice
ITC blocked on purchase of motor vehicles and conveyances — except when used for making taxable supplies of transport, training, or when you are in the business of selling vehicles.
ITC blocked on food, beverages, outdoor catering, and club memberships — except when these are used to make an outward taxable supply of the same category.
ITC blocked on goods or services used for personal consumption by employees or directors. Office supplies are fine — employee gifts and personal perks are not.
ITC blocked on construction of immovable property for own use — like building your office or warehouse. But if you are a builder constructing for sale, ITC is available.
Businesses registered under the composition scheme cannot claim any ITC. This is the trade-off for the lower flat tax rate under composition.
ITC must be reversed if goods are lost, stolen, destroyed, written off, or given as free samples. The credit claimed earlier must be paid back.
Step 1: Collect valid tax invoices. Every purchase must have a proper tax invoice from a GST-registered supplier with their GSTIN, your GSTIN, HSN codes, and tax breakup. Without a valid invoice, ITC is denied.
Step 2: Record purchase invoices in your billing software. In myBillPlease, go to Purchase Invoices and record each purchase with supplier details, item details, and GST amounts. The system stores this data for GSTR-3B and GSTR-2B reconciliation.
Step 3: Match with GSTR-2B. GSTR-2B is an auto-populated statement based on your suppliers' GSTR-1 filings. Your purchase invoices should match what appears in GSTR-2B. Mismatches mean either your supplier didn't report the invoice, or there is a data error. myBillPlease's GSTR-2B reconciliation highlights these mismatches so you can resolve them before filing.
Step 4: Claim ITC in GSTR-3B. In your monthly GSTR-3B return, Table 4 captures all ITC — eligible ITC from GSTR-2B, ITC reversed, and net ITC available. The net ITC reduces your output tax liability. If ITC exceeds output tax, the balance carries forward to the next month.
Step 5: Pay only the difference. Your final tax payment = Output Tax - Input Tax Credit. If you collected Rs 50,000 in GST on sales and have Rs 35,000 in ITC from purchases, you pay Rs 15,000 to the government.
GSTR-2B is the single most important document for ITC claims. It is an auto-generated statement available on the GST portal that shows all the invoices your suppliers have reported in their GSTR-1. If an invoice appears in your GSTR-2B, you can safely claim ITC on it. If it does not appear, claiming ITC is risky.
The government matches your ITC claims in GSTR-3B against what appears in GSTR-2B. Any claim beyond what GSTR-2B shows triggers an ITC mismatch — which leads to GST notices, interest, and potential penalties.
How to reconcile: Download GSTR-2B from the portal. Compare it with your purchase register. Invoices that match — safe to claim. Invoices missing from GSTR-2B — contact your supplier and ask them to include it in their next GSTR-1. Do not claim ITC on invoices not in GSTR-2B.
myBillPlease automates this. Record your purchase invoices in the system. When GSTR-2B data is available, the reconciliation report shows matched, unmatched, and excess invoices. Fix mismatches before filing GSTR-3B. This is available in the Starter plan — along with all GST reports exportable as Excel for your CA. See pricing for details.
The GST 2.0 rate changes in September 2025 affect ITC in several ways:
Items moved from 12% to 5%: If you buy inputs that moved to 5%, your ITC on those purchases drops. But if you also sell products that moved to 5%, your output tax drops equally. Net effect may be neutral.
Items moved from 28% to 18%: Less ITC available on inputs like white goods. But the items you sell at 18% instead of 28% generate less output tax. Overall, the reduced rate benefits consumers while keeping the ITC chain intact.
Insurance at 0%: Health and life insurance premiums are now GST-free. If your business pays employee health insurance, you no longer get ITC on it (because there is no tax to credit). But you also pay less for insurance overall.
New 40% items: If your business purchases items at 40% (unlikely for most), the ITC is higher. But these are mostly tobacco and luxury goods — not typical business inputs.
The key takeaway: update your product and purchase records with the new GST rates. Your ITC calculations will adjust automatically if your billing software uses the correct rates. In myBillPlease, update product GST rates once — all future invoices and ITC calculations use the new rates. Check our GST calculator to verify amounts.
