Section 155 of CGST Act: Burden of Proof for Input Tax Credit

Section 155 of the Central Goods and Services Tax Act, 2017 places the burden of proving eligibility for input tax credit (ITC) on the person who claims the credit.

Updated: 15 September 2026 | Chapter XXI - Miscellaneous

Text of Section 155 - Burden of proof

"Where any person claims that he is eligible for input tax credit under this Act, the burden of proving such claim shall lie on such person."

In practical terms, a taxpayer cannot rely only on the fact that an ITC amount appears in a return or system-generated statement. When eligibility is questioned, the claimant must be able to establish that the credit satisfies the applicable provisions of the CGST Act and the CGST Rules.

Relationship with Section 16 of the CGST Act

Section 16 governs eligibility and conditions for taking input tax credit. Accordingly, a person relying on an ITC claim should be in a position to demonstrate compliance with the conditions that apply to that claim, including possession of the prescribed tax document, receipt of goods or services or both, satisfaction of the statutory tax-payment condition, furnishing of the required return, and compliance with applicable time limits and other restrictions.

The exact evidence required depends on the facts. For example, documentary records may be examined to establish the underlying supply, receipt of goods or services, the tax document, accounting treatment, payment-related requirements, return reporting, reversals or reclaims, and whether the credit is blocked or otherwise restricted.

Section 155 and Form GSTR-2B

Form GSTR-2B is an important ITC statement, but GST portal guidance expressly cautions that there can be situations in which ITC is not available even though the system does not mark it as unavailable. The taxpayer is advised to self-assess eligibility and make the appropriate claim or reversal in Form GSTR-3B.

Important: Reflection of an invoice or credit in GSTR-2B should therefore be read together with the statutory eligibility conditions. Section 155 makes the claimant responsible for proving the claim when it is disputed.

Documents and evidence commonly relevant to an ITC claim

AreaExamples of relevant material
Tax documentTax invoice, debit note or other document prescribed under the GST law.
Receipt of supplyGoods receipt records, e-way bill where applicable, delivery documents, service records, contracts, work completion material or other evidence suited to the transaction.
Books and accountingPurchase register, ledger entries, stock records, expense or asset records and reconciliation statements.
GST return trailRelevant GSTR-2B and GSTR-3B details, supplier-reported information and reconciliations.
Payment and reversalsPayment records and evidence concerning any reversal, reclaim or other condition applicable under the Act or Rules.
Eligibility restrictionsMaterial showing that the credit is not barred or restricted under provisions such as Section 17(5), where relevant.

Practical compliance approach

A taxpayer claiming ITC should maintain a clear audit trail from the tax invoice to the underlying supply, books of account and GST returns. Periodic reconciliation of purchase records with GSTR-2B and GSTR-3B can help identify missing invoices, duplicate claims, reversals, reclaims and other discrepancies before they become the subject of a notice or demand proceeding.

Where the GST system identifies a specified difference between ITC available in GSTR-2B and ITC claimed in GSTR-3B or GSTR-3BQ, the GST portal provides for an intimation and response process through Form GST DRC-01C. This procedural mechanism does not replace the underlying requirement to establish ITC eligibility under the Act.
