Form GST DRC-01A pre-notice intimation and how to reply in Part B

What DRC-01A is and why it arrives

Form GST DRC-01A is titled "Intimation of tax ascertained as being payable under section 73(5) / 74(5) / 74A(8) / 74A(9)". It is issued before a show cause notice, and its whole purpose is to let a taxpayer settle a liability the officer has worked out, at a materially lower cost than fighting the notice.

It usually arrives after one of three things. Either you replied to an ASMT-10 and the officer was not satisfied, or the officer picked up a data mismatch directly, or an audit under section 65 or an investigation has thrown up a figure. In every case the notice comes with an annexure setting out the grounds, the tax period, and the tax, interest and penalty proposed.

Do not confuse DRC-01A with DRC-01. DRC-01 is the summary of a show cause notice and starts adjudication. DRC-01A is pre-notice correspondence. Nothing in a DRC-01A is recoverable. There is no liability posted to your electronic liability register at this stage.

The rule, the parts and the reply route

There is no statutory reply period fixed in Rule 142(1A). The officer specifies the date in Part A. If the time given is unreasonably short for the volume of records involved, ask in writing for an extension, on the record, and state what you are collating. Officers usually accommodate a specific and reasoned request; they rarely accommodate silence.

Is a DRC-01A compulsory before a show cause notice?

This is a genuinely contested point and you should know both sides. Until 15 October 2020, Rule 142(1A) said the officer "shall" communicate the details before serving the notice. Notification 79/2020-Central Tax replaced "shall" with "may". For periods governed by the earlier wording, several High Courts, including the Jharkhand High Court, have quashed show cause notices issued without a DRC-01A. For the post-amendment wording, the dominant view is that the intimation is directory rather than mandatory, although some benches have still set aside proceedings where the absence of a DRC-01A caused demonstrable prejudice. Do not build your defence on the absence of a DRC-01A alone. Treat it as a supporting ground, not a primary one.

The arithmetic of paying now against fighting later

This is the part that decides most DRC-01A responses, and it is worth setting out precisely.

Work the numbers on your actual figures before deciding. On a ₹4,00,000 tax demand under section 73 where you know the ground is good against you, paying at the DRC-01A stage costs tax plus interest and nothing else. Losing at adjudication costs the same tax and interest plus ₹40,000 penalty, plus the cost of the reply and the hearing. Under section 74 the same demand costs ₹60,000 in penalty now against ₹4,00,000 later, which is why fraud allegations must be assessed quickly and coldly rather than defensively.

Two cautions. First, paying under section 73(5) or 74(5) does not stop the officer issuing a notice for anything he considers short-paid; section 73(7) and 74(7) expressly allow that. Second, payment made under protest to buy peace can be used against you on the same issue in later years, so record your position clearly in Part B even when you pay.

Interest, and the parts people get wrong

Interest under section 50(1) is 18 per cent per annum. Rule 88B(1) restricts interest on a belated return to the portion of tax discharged through the electronic cash ledger, but that relief falls away once proceedings under section 73, 74 or 74A have commenced, which for these purposes means the notice stage. Rule 88B(2) covers everything else, charging interest on the unpaid tax from the due date to the date of payment.

For input tax credit, section 50(3) with Rule 88B(3) charges 24 per cent per annum, and only where credit was wrongly availed and utilised. The Explanation treats credit as utilised when the balance in the electronic credit ledger falls below the amount of the wrongly availed credit. If you maintained a credit balance above that amount throughout, and then reversed, there is no interest. Officers routinely compute 24 per cent from the date of availment. Attach the credit ledger to Part B and the number usually comes down substantially.

Answering the annexure

The grounds in a DRC-01A annexure are the same family as an ASMT-10, but the officer has usually already rejected your first explanation, so the reply has to be more evidential and less narrative.

On outward supply mismatches, produce the invoice-level reconciliation with amendment tables and credit notes mapped, and state clearly whether the difference is timing or substantive. Since July 2025 the liability tables of GSTR-3B have been locked to GSTR-1 and GSTR-1A, so this ground is largely historical, but for FY 2017-18 to 2024-25 it is still live.

On input tax credit against GSTR-2B, separate the credits into buckets: credit where the supplier filed late and the invoice appeared in a subsequent 2B, credit on imports evidenced by the bill of entry and ICEGATE data, credit distributed by an input service distributor, and credit on tax paid under reverse charge which never appears in 2B. Only the residue is genuinely in dispute.

On section 16(2)(c), where the supplier reported the invoice but did not pay, follow Circular 183/15/2022-GST for FY 2017-18 and 2018-19 and Circular 193/05/2023-GST for 1 April 2019 to 31 December 2021. Obtain a chartered accountant or cost accountant certificate with UDIN where the supplier-wise difference exceeds ₹5 lakh, and a supplier certificate below that. Where the supplier genuinely defaulted, say plainly in Part B that the issue is unsettled: the Calcutta, Gauhati and Karnataka High Courts have protected bona fide recipients, while the Patna, Kerala and Andhra Pradesh High Courts have upheld denial on the plain words of the section.

On reverse charge, reconcile the freight, legal and professional, security, sponsorship, director and rent ledgers against Table 3.1(d) and against the credit taken in Table 4A(3). Remember that renting of commercial immovable property by an unregistered landlord to a registered tenant attracts reverse charge from 10 October 2024. Where the tax was payable and not paid, the net cost is interest and a cash outflow, since the credit is generally available.

On old section 16(4) denials, check whether sections 16(5) and 16(6), inserted retrospectively by the Finance (No. 2) Act, 2024, apply. Credit for FY 2017-18 to 2020-21 is protected if it was taken in any GSTR-3B filed up to 30 November 2021. A large number of pending demands became unsustainable on this ground alone.

DRC-03 mechanics, and the form people forget

Payment against a DRC-01A goes through Form GST DRC-03 with the cause of payment marked appropriately and the intimation reference quoted. The officer then issues DRC-04 as acknowledgement and, once the liability is fully discharged, DRC-05 concluding proceedings. Chase the DRC-05. Without it the file sits open and can resurface.

If a demand has already been posted to your electronic liability register and you pay by DRC-03, the register does not clear automatically. You must file Form GST DRC-03A to map the DRC-03 payment against the demand. This form went live on the portal in November 2024 and is one of the most common causes of taxpayers being chased for amounts they have already paid.

Mistakes that cost money

Treating DRC-01A as informal correspondence and replying by email to the officer rather than in Part B on the portal leaves no record of a reply. Paying tax but not interest means the section 73(5) or 74(5) relief does not apply, because both sections require tax and interest. Paying under the wrong head, most often CGST and SGST where IGST was payable, leaves the demand alive and forces a separate refund claim under section 77 and Rule 89(1A). Accepting a section 74 characterisation without objecting is expensive: if fraud is not established, section 75(2) requires the tax to be redetermined as if the notice had been issued under section 73, which changes the penalty from 100 per cent to 10 per cent. And chasing the section 128A waiver of interest and penalty for FY 2017-18 to 2019-20 is now pointless; that scheme required tax to be paid by 31 March 2025 and applications in SPL-01 or SPL-02 by 30 June 2025, and the window has closed.

What to attach to Part B

The invoice-level reconciliation for each disputed ground, the electronic credit and cash ledger extracts for the periods in question, GSTR-2B extracts showing where late-filed invoices actually landed, bills of entry and ICEGATE extracts for import credit, supplier certificates or CA certificates with UDIN where section 16(2)(c) is alleged, expense ledgers and agreements for reverse charge issues, the Rule 42 and 43 computation, DRC-03 challans and ARNs for any accepted amount, and a covering computation showing your admitted figure against the officer's figure line by line.

Doing it yourself or getting help

A single-ground DRC-01A for a modest amount, where you know the answer and have the documents, can be handled internally. Bring in a professional where the intimation invokes section 74 or 74A on fraud grounds, where the aggregate exposure crosses roughly ₹5 lakh, where the same issue runs across several years, where the intimation follows an audit or a summons, or where you are weighing payment against contest. The decision at this stage is commercial as much as legal, and the difference between 15 per cent and 100 per cent penalty is usually worth a professional fee.
