Assessment: Self-Assessment, Verification and Provisional Duty

Three points about section 17(5) are worth making. The obligation is to give reasons, so an importer who disagrees receives a document he can appeal against. The obligation is excused only by written acceptance, so silence does not dispense with it. And the period is fifteen days, which is short and is frequently breached in practice, giving a ground of challenge.

Section 17(6) provides that where re-assessment has not been done or a speaking order has not been passed, the proper officer may audit the assessment at his office or at the premises of the importer or exporter, which is the link to the audit provisions in [Audit and Identity Verification].

Section 18: provisional assessment

Section 18(1) states when duty may be assessed provisionally. Notwithstanding anything contained in the Act but without prejudice to section 46, provisional assessment is available where:

(a) the importer or exporter is unable to make self-assessment and makes a request in writing to the proper officer for assessment;

(b) the proper officer deems it necessary to subject the goods to any chemical or other test;

(c) the importer or exporter has produced all the necessary documents and furnished full information, but the proper officer deems it necessary to make further enquiry;

(d) necessary documents have not been produced or information has not been furnished and the proper officer deems it necessary to make further enquiry.

In each case the proper officer may direct that the duty be assessed provisionally, on the importer or exporter executing a bond in the prescribed form binding himself to pay the deficiency, and furnishing such security as the proper officer deems fit.

Section 18(1A), inserted by the Finance Act 2025, requires the importer or exporter to furnish such documents or information as may be required for finalisation within the prescribed time.

Section 18(1B) is the new discipline and the examinable currency point. The proper officer shall finalise the provisional assessment within two years from the date of the provisional assessment under sub-section (1). The first proviso allows the Principal Commissioner or Commissioner of Customs, on sufficient cause being shown and for reasons to be recorded in writing, to extend the period by a further one year. A further proviso deals with cases where the finalisation is held up because information is awaited, for instance from an authority outside India, excluding that period from the computation.

Why section 18(1B) matters. Before it, provisional assessments could remain open indefinitely. An importer's bond stayed alive, his security stayed with the department, and his liability was unquantified for years. A two-year outer limit, extendable by one, converts an open-ended exposure into a bounded one, and it is a genuine improvement that a critical answer should acknowledge while noting that the exclusion for awaited information leaves a gap.

Sections 18(2) to 18(5) deal with the consequences of finalisation. On final assessment the amount paid provisionally is adjusted; where duty is payable it is demanded, and where an excess was paid it is refunded. Interest is payable by the importer on any amount short paid, from the first day of the month in which the duty was provisionally assessed till the date of payment, and interest is payable to him on a refund of excess, at the rates fixed under sections 28AA and 27A respectively. The refund is subject to the unjust enrichment test: the amount is credited to the Consumer Welfare Fund unless the claimant shows that the incidence of duty was not passed on.

Section 18A: voluntary revision of entry after clearance

Section 18A, inserted by the Finance Act 2025 and in force from 1 May 2025, is the most significant recent addition to this part of the Act.

Section 18A(1) provides that, notwithstanding anything contained in section 149, the importer or exporter of goods may, after the clearance of the goods, revise an entry already made in respect of them, in the prescribed form and manner and within the prescribed time.

The scheme has these features. Where the revision discloses duty short paid, the importer or exporter pays it with interest under section 28AA. Where it discloses duty paid in excess, the revised entry is treated as a claim for refund under section 27, so the refund machinery, including the unjust enrichment test, applies. The revision is not available in prescribed cases, including where the matter is already under audit, investigation or reassessment, so it cannot be used to pre-empt a proceeding already begun.

Its significance is that it answers ITC Ltd. That decision had held that a refund claim on a self-assessed bill of entry is not maintainable unless the assessment is first modified in appeal, because a self-assessment is an order. The practical consequence was that an importer who assessed himself wrongly had to appeal against his own return, within the appellate limitation, before he could recover anything. Section 18A restores a direct route: he may revise the entry and claim, without an appeal. The gap lasted from September 2019 to May 2025, and an answer that states the position without noticing section 18A is describing law that has changed.

Distinctions

Worked example

Talegaon Pharma imports an active ingredient and self-assesses under section 17(1), claiming a concessional rate under an exemption notification. The proper officer doubts whether the goods answer the notification's description and orders a chemical test.

Provisional assessment follows under section 18(1)(b), since the officer deems it necessary to subject the goods to a chemical test. Talegaon executes a bond binding itself to pay the deficiency and furnishes security, and the goods are released. Under section 18(1B) the officer must finalise within two years, extendable by one year by the Principal Commissioner or Commissioner for recorded reasons.

Suppose the test shows the goods do not answer the notification. On finalisation the differential duty is demanded, with interest from the first day of the month in which the provisional assessment was made until payment.

Now change the facts. Suppose the goods were cleared on a final self-assessment at the full rate, and three months later Talegaon discovers it was entitled to the concession after all.

Before 1 May 2025 its position was awkward. ITC Ltd held that a refund claim on a self-assessed bill of entry is not maintainable unless the assessment is modified in appeal, so Talegaon would have had to appeal under section 128 against its own self-assessment, within sixty days, before claiming under section 27.

Since 1 May 2025 section 18A supplies the direct route. Talegaon may revise the entry after clearance in the prescribed form and time, and because the revision discloses an excess payment it is treated as a claim for refund under section 27, subject to the unjust enrichment test, so Talegaon must also show that it did not pass on the incidence of the duty to its customers.

One limit must be stated. If the department had already commenced an audit or investigation on that bill of entry, section 18A would not be available, and Talegaon would be back to the appellate route.

What it does NOT mean

It does not mean the officer no longer assesses. He verifies under section 17(2), may re-assess under section 17(4), must pass a speaking order under section 17(5) where the re-assessment is contrary to the self-assessment and is not accepted in writing, and may audit under section 17(6).

It does not mean a provisional assessment can be left open. Section 18(1B) requires finalisation in two years, extendable by one.

It does not mean section 18A is a general amnesty. It is unavailable in the prescribed cases, including where an audit, investigation or reassessment is already on foot, and a revision showing a shortfall carries interest under section 28AA.

And it does not mean ITC Ltd is no longer law. It remains the law on the appealability of a self-assessment; what section 18A does is provide an alternative route to a refund that does not require an appeal.

Quick revision

• Section 17(1): the importer or exporter shall self-assess the duty on goods entered under section 46 or section 50. 17(2): the proper officer may verify the entries and the self-assessment, and examine or test the goods. 17(3): he may require production of contracts, broker's notes, insurance policies, catalogues and other documents and information. 17(4): where the self-assessment is not done correctly he may re-assess. 17(5): where the re-assessment is contrary to the self-assessment and is not accepted in writing, a speaking order within fifteen days. 17(6): audit where no re-assessment or speaking order has been made.
• Section 18(1): provisional assessment where the importer or exporter cannot self-assess and asks in writing (a); the officer deems a chemical or other test necessary (b); documents and information are complete but further enquiry is needed (c); or documents or information are missing and further enquiry is needed (d). A bond and such security as the officer deems fit are required.
• Section 18(1A) (2025): the importer or exporter must furnish documents or information needed for finalisation within the prescribed time.
• Section 18(1B) (2025, in force 1 May 2025): finalise within two years, extendable by the Principal Commissioner or Commissioner by one further year on sufficient cause and recorded reasons, with an exclusion for periods spent awaiting information.
• On finalisation: adjustment, with interest payable by the importer on a shortfall and interest payable to him on an excess, and the refund subject to unjust enrichment, going to the Consumer Welfare Fund unless the incidence was not passed on.
• Section 18A (2025, in force 1 May 2025): voluntary revision of an entry after clearance, notwithstanding section 149, in the prescribed form, manner and time. Short payment is paid with interest under section 28AA; excess payment is treated as a claim for refund under section 27. Not available in prescribed cases such as goods under audit, investigation or reassessment. It answers ITC Ltd v. Commissioner of Central Excise, Kolkata IV, decided on 18 September 2019, 2019 INSC 1049, which had required an appeal against one's own self-assessment before a refund could be claimed.

Test yourself

1. Explain the scheme of assessment under section 17 and the safeguards it contains. Section 17(1) places the primary obligation on the trader: an importer entering goods under section 46, or an exporter entering goods under section 50, shall self-assess the duty leviable. The department's role is subsequent and selective. Section 17(2) permits the proper officer to verify the entries and the self-assessment, and for that purpose to examine or test the goods. Section 17(3) allows him to require production of any contract, broker's note, insurance policy, catalogue or other document and to require information, which the person concerned is bound to furnish. Section 17(4) empowers him, where verification, examination, testing or any other material shows that the self-assessment has not been done correctly, to re-assess the duty, without prejudice to any other action under the Act. Section 17(6) permits an audit of the assessment, at his office or at the premises of the importer or exporter, where no re-assessment has been done or no speaking order passed.

The principal safeguard is section 17(5). Where a re-assessment under sub-section (4) is contrary to the self-assessment, and the importer or exporter has not confirmed his acceptance of it in writing, the proper officer must pass a speaking order on the re-assessment within fifteen days of the re-assessment of the bill of entry or shipping bill. Its importance is threefold: it converts an administrative revision into a reasoned order, so that the trader knows the case against him; it gives him a document capable of appeal under section 128; and it is dispensed with only by express written acceptance, so acquiescence or silence does not excuse it. The fifteen-day period is short and is often missed in practice, and a failure to pass the order is a substantial ground of challenge to the re-assessment.

2. When may duty be assessed provisionally, and what discipline now governs finalisation? Section 18(1) permits provisional assessment in four situations: where the importer or exporter is unable to make a self-assessment and requests assessment in writing; where the proper officer deems it necessary to subject the goods to a chemical or other test; where all necessary documents have been produced and full information furnished but the officer deems further enquiry necessary; and where documents or information have not been produced or furnished and the officer deems further enquiry necessary. In each case the officer may direct provisional assessment on the importer or exporter executing a bond in the prescribed form, binding himself to pay the deficiency, and furnishing such security as the officer deems fit.

The discipline on finalisation is new. Section 18(1A), inserted by the Finance Act 2025, obliges the trader to furnish the documents or information required for finalisation within the prescribed time. Section 18(1B), in force from 1 May 2025, requires the proper officer to finalise the provisional assessment within two years from the date of the provisional assessment, with a proviso permitting the Principal Commissioner or Commissioner of Customs, on sufficient cause shown and for reasons recorded in writing, to extend that by a further year, and a further proviso excluding periods during which finalisation is held up awaiting information, for example from an authority outside India. Before these amendments a provisional assessment could remain open indefinitely, keeping the bond alive, the security with the department and the liability unquantified for years. On finalisation the provisional payment is adjusted, interest runs against the trader on a shortfall from the first day of the month of the provisional assessment and in his favour on an excess, and any refund is subject to the unjust enrichment test, being credited to the Consumer Welfare Fund unless he shows the incidence was not passed on.

3. What does section 18A provide and what problem does it solve? Section 18A, inserted by the Finance Act 2025 and in force from 1 May 2025, permits an importer or exporter, notwithstanding section 149, to revise an entry already made in respect of goods after their clearance, in the prescribed form and manner and within the prescribed time. If the revision shows duty short paid, it is paid with interest under section 28AA. If it shows duty paid in excess, the revised entry is treated as a claim for refund under section 27, and so passes through the refund machinery including the unjust enrichment test. The facility is excluded in prescribed cases, notably where the goods or the entry are already the subject of audit, investigation or reassessment, so that it cannot be used to forestall a proceeding already begun.

The problem it solves was created by ITC Ltd v. Commissioner of Central Excise, Kolkata IV, decided on 18 September 2019, 2019 INSC 1049. There the Supreme Court held that a self-assessment is itself an order of assessment, appealable under section 128, and that a refund authority cannot sit in appeal over an assessment which stands; a refund claim on a self-assessed bill of entry was therefore not maintainable unless the assessment was first modified in appeal. Since 2011 the overwhelming majority of bills of entry are self-assessed, so the practical effect was that an importer who had made an honest error against himself had to appeal against his own return, within the appellate limitation, before he could recover a rupee. Section 18A restores a direct administrative route to correction, and it does so symmetrically, catching under-payments as well as over-payments.

4. Why was self-assessment introduced, and what did the state give up in return? It was introduced because prior assessment of every consignment by an officer could not be reconciled with the volume of modern trade. Under the earlier model each bill of entry was examined and assessed before clearance, which meant that classification and valuation were settled at the port for millions of consignments a year, and the resulting delay was itself a cost to trade and to the economy. Section 17(1) reverses the order: the importer or exporter assesses and pays, the goods move, and the department verifies afterwards on a selective and risk-based footing.

What the state gave up is prior scrutiny, and what it took in exchange is a set of subsequent powers. It retained verification and examination under section 17(2), the power to demand documents and information under section 17(3), re-assessment under section 17(4), audit under section 17(6) and the separate audit provisions of Chapter XIIA, and the recovery machinery of section 28 with its two-year and five-year limitation periods. It also shifted responsibility: because the trader now makes the assessment, a false or incorrect declaration is his act, which is why the penalty provisions in sections 112, 114A and 114AA and the offence in section 135 carry the weight they do. And one consequence was unintended: because a self-assessment is an assessment, it is an appealable order, which is what produced the difficulty in ITC Ltd that section 18A was eventually enacted to cure.
