Section 64 CGST Act — Summary Assessment in Special Cases

1. Why Section 64 matters

Searches such as “Section 64 CGST Act”, “GST summary assessment”, “summary assessment under GST”, “ASMT-16”, “ASMT-17”, “ASMT-18”, “GST revenue protection assessment” and “30 days withdrawal of summary assessment” relate directly to this provision.

Section 64 is not the normal method by which every GST liability is assessed. It is a special and exceptional mechanism designed for situations where the department has evidence of a tax liability and believes that waiting for the ordinary process may adversely affect government revenue.

2. Section 64 in very simple language

Imagine the department obtains reliable evidence that a person has a significant GST liability. At the same time, there is a reason to believe that delaying the assessment could harm revenue—for example, there may be a serious risk that the amount will become difficult to recover.

In such a special situation, the proper officer can use Section 64 after obtaining prior permission from an Additional Commissioner or Joint Commissioner.

The assessment is issued immediately through ASMT-16. The law then provides a specific mechanism for the taxable person to seek withdrawal of the order within 30 days.

3. What is summary assessment?

“Summary” means that the law permits the department to determine the liability without following the ordinary full assessment sequence first, because the circumstances are considered urgent from a revenue-protection perspective.

It is therefore different from routine scrutiny or a normal tax determination proceeding.

4. Three core conditions

Section 64 should be read carefully because three central conditions work together.

These are not merely administrative preferences. They define the special circumstances in which Section 64 can be used. The current statutory text expressly contains these requirements. citeturn0search0

5. Prior approval requirement

Before making the Section 64 assessment, the proper officer must obtain previous permission of the Additional Commissioner or Joint Commissioner.

This is an important safeguard because Section 64 is an exceptional power. The approving senior officer should therefore be satisfied that the statutory conditions for summary assessment exist.

6. Is a prior hearing required?

Section 64 does not contain the same express pre-assessment hearing requirement found in Section 63.

The reason is the exceptional nature of the provision: the law allows immediate summary assessment where delay may adversely affect revenue.

However, the taxpayer is given an important post-assessment remedy. Under Section 64(2), the taxable person can apply for withdrawal of the summary assessment order within 30 days of receiving it. The Additional Commissioner or Joint Commissioner can also withdraw an erroneous order on his own motion.

7. Unascertainable taxable person and goods

Section 64 contains a special rule for cases involving goods.

If the taxable person to whom the liability belongs cannot be ascertained, the person in charge of the goods can be deemed to be the taxable person liable to be assessed and liable to pay tax and other amounts due under the section.

This is an unusual but important situation. It is designed to prevent uncertainty about the person liable from making immediate revenue protection impossible.

8. Complete statutory structure

The current text expressly refers to Section 74A for the newer tax periods covered by that provision. citeturn0search0

9. ASMT-16 assessment order

Rule 100 provides that the summary assessment order under Section 64(1) is issued in FORM GST ASMT-16.

ASMT-16 is therefore the key document a taxpayer receives when a Section 64 summary assessment has been made.

On receiving ASMT-16, immediately record:

• date of receipt/service;
• financial/tax period involved;
• tax assessed;
• interest and other amounts;
• facts stated by the department;
• approval details where available; and
• the 30-day deadline for withdrawal application.

Rule 100 specifically prescribes ASMT-16 for Section 64(1). citeturn0search1

10. DRC-07 demand summary

The Section 64 assessment order is accompanied by an electronic summary uploaded in FORM GST DRC-07.

Therefore, the taxpayer should compare ASMT-16 with DRC-07 and verify that the demand appearing electronically corresponds with the assessment order.

11. ASMT-17 withdrawal application

If the taxable person believes the summary assessment is erroneous, Section 64(2) allows an application for withdrawal within 30 days from the date of receipt of the order.

Rule 100 prescribes FORM GST ASMT-17 for this application.

A strong application should explain why the summary assessment is incorrect and provide supporting documents. It should not simply state that the taxpayer disagrees.

12. Important 30-day period

The 30-day period is extremely important.

The taxpayer must make the withdrawal application within 30 days from the date of receipt of the Section 64 order.

The current Section 64(2) expressly provides this 30-day mechanism. citeturn0search0

13. ASMT-18 withdrawal/rejection order

Rule 100 provides that the order withdrawing the summary assessment, or rejecting the withdrawal application, is issued in FORM GST ASMT-18.

This three-form sequence makes Section 64 different from the ordinary scrutiny process under Section 61.

14. What happens after withdrawal?

Withdrawal does not mean that the tax liability automatically disappears.

Section 64(2) provides that where the Additional Commissioner or Joint Commissioner considers the summary assessment erroneous, the order can be withdrawn and the department can follow the ordinary determination procedure under Section 73, Section 74 or Section 74A, as applicable.

This gives the department a route to determine the actual liability through the appropriate ordinary procedure rather than leaving the revenue issue unresolved. citeturn0search0

15. Section 73/74/74A connection

Because Section 64 now expressly cross-references Section 74A, an article written only from the original 2017 wording would be incomplete for current readers. citeturn0search0

16. What evidence can trigger Section 64?

The law does not say that one particular document automatically triggers Section 64. It refers broadly to any evidence showing a tax liability coming to the notice of the proper officer.

The key is not simply possession of information. The officer must also satisfy the revenue-protection and delay-risk conditions.

17. Meaning of “protect the interest of revenue”

This phrase is central to Section 64.

In simple language, the provision is meant for situations where waiting for the normal assessment route could create a real risk to government revenue.

Examples could include circumstances where:

• taxable goods are found and immediate identification/payment is necessary;
• there is a credible risk that the tax liability will become difficult to recover;
• the relevant transaction or taxable person may otherwise become untraceable; or
• delay would materially prejudice collection of the tax.

21. Detailed practical examples

Example 1 — Unaccounted goods

Departmental officers find goods in a vehicle or godown and the person liable to tax is not immediately ascertainable. The Section 64 goods proviso can become relevant if the statutory conditions are satisfied.

Example 2 — Evidence of large tax liability

The department obtains reliable evidence of taxable supplies and has sufficient grounds to believe that delay could prejudice revenue. After prior approval, a summary assessment may be made.

Example 3 — Prior approval missing

If the statutory prior permission of the Additional/Joint Commissioner has not been obtained, the Section 64 procedure raises a fundamental procedural issue.

Example 4 — Taxpayer disputes ASMT-16

The taxpayer receives ASMT-16 and believes the tax liability is wrongly computed. The taxpayer can apply for withdrawal within 30 days using ASMT-17.

Example 5 — Erroneous order recognised by senior officer

The Additional Commissioner or Joint Commissioner independently considers the order erroneous. The officer can withdraw it on own motion and the applicable normal determination procedure can follow.

Example 6 — Goods owner cannot be identified

Goods are found, but the taxable person to whom the liability belongs cannot be ascertained. The person in charge of the goods may be treated as the taxable person under the special proviso, subject to Section 64 conditions.

Example 7 — Delay not harmful to revenue

If the facts show only an ordinary tax dispute without a genuine revenue-risk reason for immediate action, Section 64 should not be treated as a routine shortcut.

Example 8 — Construction material

Taxable construction materials are found at a site without proper accounting and the underlying taxable person cannot be readily ascertained. The special goods proviso may become relevant depending on the facts.

Example 9 — Withdrawal and normal assessment

The summary assessment is withdrawn as erroneous. The department can then use the appropriate Section 73/74/74A process to determine the actual liability.

Example 10 — DRC-07 reconciliation

The taxpayer receives ASMT-16 and sees a corresponding DRC-07 demand. Both should be reconciled before payment or withdrawal proceedings are initiated.

22. Construction and infrastructure examples

Unaccounted project material

Construction projects often hold large quantities of steel, cement, machinery and other materials. If taxable goods are found without proper supporting records, the department may investigate ownership and tax liability.

Site records

Gate registers, GRNs, purchase invoices, delivery challans, e-way bills and project stock registers can be critical evidence to establish the actual position.

Subcontractor material

Where materials belong to a principal contractor but are held at a subcontractor's site, ownership and movement documents should be maintained carefully.

RA bills and services

Section 64 can also be relevant to evidence showing tax liability on services, but the special urgency/revenue-risk conditions must still be satisfied.

23. Documents and evidence

• tax invoices;
• purchase and sales registers;
• stock registers;
• delivery challans;
• e-way bills;
• contracts and work orders;
• bank statements;
• customer/vendor confirmations;
• project-wise records;
• GRNs and gate records;
• previous GST returns;
• tax payment records;
• ASMT-16, ASMT-17 and ASMT-18; and
• DRC-07 demand records.
