When a business obtains GST registration, the GST previously paid on inventory, capital goods, and finished products held in stock becomes eligible for Input Tax Credit (ITC). Form ITC-01 is the mandatory declaration filed on the GST portal that enables newly registered taxpayers to claim this credit on their existing stock from the date of registration.
What Is Form ITC-01 and Why Is It Required?
Businesses operating before obtaining GST registration often hold substantial inventory, raw materials, and capital assets on which GST has already been paid to suppliers. However, this embedded tax cannot be claimed as ITC until the business is formally registered under GST. Form ITC-01 bridges this gap by providing a structured mechanism for declaring pre-registration stock and claiming the associated tax credit.
The form serves a critical commercial purpose. Without it, the GST embedded in existing inventory would become a permanent cost to the business, increasing product prices and reducing competitiveness. The ITC-01 mechanism ensures that the fundamental GST principle of taxing only value addition is maintained even during the transition from unregistered to registered status.
Once filed successfully, the claimed ITC is credited to the taxpayer’s electronic credit ledger on the GST portal. This credit can then be utilised to offset output tax liability in subsequent GSTR-3B filings, providing immediate working capital relief.
Situations Requiring ITC-01 Filing
Form ITC-01 must be filed under four specific scenarios defined in Section 18 of the CGST Act.
Section 18(1)(a): Mandatory Registration
When a person applies for GST registration within 30 days of becoming liable for GST (because their turnover exceeded the threshold), they can claim ITC on inputs held in stock on the day immediately preceding the date when the liability to pay tax commenced. This is a one-time claim.
Section 18(1)(b): Voluntary Registration
When a person voluntarily opts for GST registration even though their turnover is below the mandatory threshold, ITC is available on stock held on the day immediately preceding the date of grant of registration. This is also a one-time claim.
Section 18(1)(c): Exit from Composition Scheme
When a person exits the Composition Scheme but continues to register as a regular taxpayer, they can claim ITC on stock held on the day before they switch to the regular regime. Since composition dealers cannot claim ITC, this provision ensures credit availability upon switching. This can be exercised once per year.
Section 18(1)(d): Exempt Supply Becomes Taxable
When goods or services previously exempt from GST become taxable following a rate change or exemption withdrawal, the supplier can claim ITC on inputs held in stock relating to those newly taxable supplies. The cut-off date is the day preceding the date the supply becomes taxable. This can be exercised once per month.
ITC Claim Deadlines and Cut-off Dates
| Scenario | Cut-off Date for Stock | Claim Frequency | Filing Deadline |
| Mandatory registration [18(1)(a)] | Day before liability date | Once | Within 30 days of eligibility |
| Voluntary registration [18(1)(b)] | The day before registration grant | Once | Within 30 days of registration |
| Exit from composition [18(1)(c)] | The day before switching to regular | Once per year | Within 30 days of switching |
| Exempt becomes taxable [18(1)(d)] | The day before the supply becomes taxable | Once per month | Within 30 days of the change |
For example, if Mr A, a trader, obtains voluntary registration on December 29, 2024, he can claim ITC on all eligible inputs and capital goods held as of December 28, 2024. The ITC-01 must be filed by January 28, 2025.
Categories of ITC Available Under Form ITC-01
Not all categories of stock are eligible for ITC under every scenario. The availability depends on the specific section under which the claim is made.
| Category | 18(1)(a) Mandatory Reg | 18(1)(b) Voluntary Reg | 18(1)(c) Composition Exit | 18(1)(d) Exempt to Taxable |
| Inputs held in stock | Yes | Yes | Yes | Yes |
| Inputs in semi-finished goods | Yes | Yes | Yes | Yes |
| Inputs in finished goods | Yes | Yes | Yes | Yes |
| Capital goods | No | No | Yes | Yes |
| Services | No | No | No | No |
ITC on services is not available through Form ITC-01 under any scenario. ITC on capital goods is restricted to composition scheme exits and exempt-to-taxable transitions only. For capital goods, the available ITC is reduced by 5% per quarter (or part thereof) from the date of the original invoice to the date of the ITC claim.
Step-by-Step Filing Procedure on the GST Portal
Step 1: Log in to the GST portal. Access services.gst.gov.in using your GSTIN credentials.
Step 2: Navigate to ITC forms. Go to Services, then Returns, then ITC Forms, then select ITC-01.
Step 3: Select the applicable section. Choose the relevant provision: Section 18(1)(a), (b), (c), or (d) under which the claim is being made. The form structure adapts based on the selected section.
Step 4: Enter stock details. For each item, provide the supplier’s GSTIN, invoice number and date, description of goods with HSN code, quantity and unit of measurement, taxable value, and the GST amount broken into CGST, SGST, or IGST.
Step 5: Upload CA/CMA certificate (if applicable). When the total ITC claimed exceeds Rs. 2 lakh, a certificate from a practising Chartered Accountant or Cost Accountant must be uploaded. The certificate confirms that the declared stock details are accurate and the invoices are genuine.
Step 6: Preview and verify. Review all entries carefully. Form ITC-01 cannot be revised after filing. Any errors in invoice details, quantities, or GST amounts will remain in the filed declaration.
Step 7: Submit using DSC or EVC. File the form using a Digital Signature Certificate (for companies and LLPs) or Electronic Verification Code (for other entities). An acknowledgement with Application Reference Number (ARN) is generated upon successful submission.
Key Considerations for Accurate Filing
Taxpayers must ensure several conditions are met for a valid ITC-01 claim. Invoices for inputs must be no older than one year from the cut-off date. Invoices for capital goods can be up to five years old. The goods must be physically in the claimant’s possession on the cut-off date. The supplier must have deposited the GST shown on the invoice with the government. Items falling under Section 17(5) blocked credits (motor vehicles for personal use, food and beverages, club memberships, etc.) cannot be claimed through ITC-01.
Additionally, businesses should reconcile their stock records with purchase invoices before filing. Any mismatch between physical stock and declared quantities may trigger scrutiny from the jurisdictional officer. Maintaining a stock register with running balances and periodic physical verification records strengthens the ITC claim.
What Happens After Filing ITC-01?
Once ITC-01 is successfully filed, the claimed credit is reflected in the electronic credit ledger on the GST portal. The taxpayer can utilise this credit to pay the output tax liability in GSTR-3B from the same period onwards.
The jurisdictional officer may verify the claim by requesting supporting documents, conducting a physical stock verification, or cross-checking the supplier’s filing status. If any portion of the claim is found ineligible, the officer can issue a demand for reversal of the excess credit with interest at 18% per annum.
