GST Basics #11: Section 16 — The Conditions for Claiming Input Tax Credit

Ravi has explained what input tax credit is. This instalment covers the conditions in Section 16 of the CGST Act you must meet before you can take it — invoice, GSTR-2B, receipt, tax paid, and the time limit.

Ravi's earlier post explained what input tax credit is — the tax you pay on your purchases, set off against the tax you collect on your sales. This instalment is about the conditions the law attaches before you can actually take it. Section 16 of the CGST Act is where they live, and every one of them has to be met.

Start with Section 16(1). Only a registered person can take credit, only on goods or services used or intended to be used in the course or furtherance of business, and the credit goes into the electronic credit ledger.

Section 16(2) is the heart of it — four conditions, all mandatory. First, you must hold a tax invoice or other prescribed tax-paying document. Second, under clause (aa), inserted from 1 January 2022, the invoice must have been reported by your supplier and communicated to you in Form GSTR-2B — if it is not in your 2B, you cannot claim it, whatever your books show. Third, you must have actually received the goods or services. Fourth, the tax must have been paid to the Government, and you must have furnished your return under Section 39.

Two provisos to watch. Where you receive goods in lots, credit is available only when the last lot arrives. And the 180-day rule: if you do not pay your supplier the invoice value plus tax within 180 days of the invoice date, the credit already taken is added back to your output tax with interest — you get it back once you pay.

Section 16(3) blocks double benefit: if you have claimed depreciation on the tax component of the cost of capital goods under the Income-tax Act, you cannot also take input tax credit on that tax. Choose one.

Section 16(4) is the time limit. Credit for an invoice or debit note cannot be taken after 30 November following the end of the financial year, or the date of filing the annual return, whichever is earlier. Two relief valves were added by the Finance (No. 2) Act, 2024: Section 16(5) reopened credit for 2017-18 to 2020-21 where the return was filed up to 30 November 2021, and Section 16(6) helps those whose registration was cancelled and later revoked.

What this means for you: reconcile your purchase register against GSTR-2B every month, clear supplier dues within 180 days, and never let the November cut-off pass on an unclaimed invoice. A credit you were entitled to but did not take in time is simply lost.
