Blocked ITC Review

Quick View

Why It Matters

Section 17(5) blocks specified credits even where expenditure has a business connection, subject to detailed exceptions.

Common disputes involve vehicles, employee benefits, health and life insurance, food and beverages, works contracts, construction and goods lost or written off.

Exceptions should be proven with the outward supply, statutory obligation, further supply or plant-and-machinery analysis.

Control Framework

Action Checklist

1. Create expense-category matrix.
2. Flag blocked codes in ERP.
3. Review vehicle and construction spend.
4. Document statutory employee benefits.
5. Reverse common credit where needed.
6. Test exceptions annually.

Practical Example

Evidence to Keep

• Invoice and contract.
• Expense purpose.
• Outward supply linkage.
• Statutory obligation evidence.
• Capitalisation record.
• ITC decision memo.

Warning Signs

Detailed Review

GST control should connect five records: commercial contract, tax invoice, movement or service evidence, accounting entry and portal return. A filing that cannot be traced back to all five records is difficult to defend.

Every reconciliation should have a clear opening balance, current-period additions, corrections, reversals, payments and closing balance. Avoid unexplained plugs that make the total match but do not identify the invoice or legal reason.

Portal data is important but not conclusive by itself. GSTR-2B, e-invoice, e-way bill and ledger data should be read with the statute, rules, notifications, contracts and actual supply evidence.

Keep original source files and final filed versions. Screenshots help explain a portal event but should not replace downloaded returns, JSON, signed invoices, acknowledgements or bank records.

For material exposure, prepare a written position memo stating facts, issue, law, alternatives, conclusion, amount and approval. The memo should record uncertainty rather than hide it.

ITC review must establish supplier, invoice, receipt, business use, tax reporting and absence of a statutory block. A purchase-register match is only one layer.

Vendor remediation should have an ageing rule: request correction, escalate commercially, defer or reverse credit where required and preserve later re-availment evidence.

Escalation Route

Start with the GST portal record, responsible business owner and tax working. Where the issue is operational, correct the source system and retain the acknowledgement. Where it is legal or disputed, obtain a reasoned professional position before payment, reply, refund or appeal.

Track the statutory or portal deadline separately from internal approval. Preserve helpdesk tickets, ARN, hearing requests, orders and payment records so a later reviewer can reproduce the entire path.

Transaction Test

Before filing or replying, prepare a one-page issue sheet showing GSTIN, tax period, transaction type, amount, applicable provision, portal form, evidence owner and due date. This prevents different teams from solving different versions of the same problem.

Reconcile tax by CGST, SGST, IGST and cess rather than only by total. A total can match even when the wrong tax head, state or period has been used, which can still create interest, cash-flow and customer-credit consequences.

Build an exception register with five statuses: identified, evidence pending, vendor or customer action, tax treatment approved and closed. Every exception should retain its original amount even after correction so the audit trail remains visible.

Test the position against the counterparty’s records. Customer ITC, vendor GSTR-1, transporter data, marketplace statements and bank receipts can expose differences that are invisible in the taxpayer’s own ledger.

The final approval should record who reviewed the legal position and who approved the return, reply, payment, refund or appeal. Material GST decisions should not remain buried in informal email chains.

Use an invoice ageing report that distinguishes missing in 2B, wrong GSTIN, duplicate, ineligible, blocked, received-not-booked and booked-not-received. Each category requires a different action.

Re-availment should link back to the original reversal month and document. Without that link, the business can claim the same credit twice or fail to reclaim it.
