Section 60 — PROVISIONAL ASSESSMENT
BLOCK 1 — VERBATIM TEXT
Marginal note — Provisional assessment
60. (1) Subject to the provisions of sub-section (2), where the taxable person is unable to determine the value of goods or services or both or determine the rate of tax applicable thereto, he may request the proper officer in writing giving reasons for payment of tax on a provisional basis and the proper officer shall pass an order, within a period not later than ninety days from the date of receipt of such request, allowing payment of tax on provisional basis at such rate or on such value as may be specified by him.
(2) The payment of tax on provisional basis may be allowed, if the taxable person executes a bond in such form as may be prescribed, and with such surety or security as the proper officer may deem fit, binding the taxable person for payment of the difference between the amount of tax as may be finally assessed and the amount of tax provisionally assessed.
(3) The proper officer shall, within a period not exceeding six months from the date of the communication of the order issued under sub-section (1), pass the final assessment order after taking into account such information as may be required for finalizing the assessment:
Provided that the period specified in this sub-section may, on sufficient cause being shown and for reasons to be recorded in writing, be extended by the Joint Commissioner or Additional Commissioner for a further period not exceeding six months and by the Commissioner for such further period not exceeding four years.
(4) The registered person shall be liable to pay interest on any tax payable on the supply of goods or services or both under provisional assessment but not paid on the due date specified under sub-section (7) of section 39 or the rules made thereunder, at the rate specified under sub-section (1) of section 50, from the first day after the due date of payment of tax in respect of the said supply of goods or services or both till the date of actual payment, whether such amount is paid before or after the issuance of order for final assessment.
(5) Where the registered person is entitled to a refund consequent to the order of final assessment under sub-section (3), subject to the provisions of sub-section (8) of section 54, interest shall be paid on such refund as provided in section 56.

BLOCK 2 — STATUTORY MAP
ELEMENT OF THE PROVISION
OPERATIVE READING
Trigger A — ‘unable to determine the value’
Genuine inability to determine taxable value under s. 15 read with Rules 27-31A. Typical scenarios: related-party / distinct-person supplies where Rule 28 OMV is uncertain and second proviso (full-ITC recipient) is unavailable; contingent consideration (price subject to future events); supplies where goods or services have not yet stabilised in commercial pricing; HO-BO cross-charge where the underlying valuation methodology is contested; supplies under contracts with price-escalation clauses pending arbitration.
Trigger B — ‘unable to determine the rate of tax’
Genuine inability to determine the applicable GST rate. Typical scenarios: a product or service that could fit two HSN / SAC entries with different rates (e.g., a multi-purpose chemical between Sl. No. X at 18% and Sl. No. Y at 12%); a composite supply with disputed principal character (e.g., solar EPC turning on works-contract vs goods classification); a product where the Government has not yet clarified the rate; pending advance ruling under s. 97.
‘Request the proper officer in writing’
Application in FORM GST ASMT-01 on the common portal with detailed reasons, supporting commercial documentation, proposed provisional rate / value, and the basis of the genuine difficulty. Pre-emptive — the application must be filed BEFORE the due date of return for the affected tax period.
‘Within a period not later than ninety days’
Hard 90-day outer limit for the proper officer to pass the provisional order in ASMT-04. May be preceded by ASMT-02 notice seeking additional information and the applicant's reply in ASMT-03.
Bond + surety / security under sub-s. (2)
FORM GST ASMT-05. Bond amount typically equal to the differential tax exposure between proposed provisional and worst-case final rate / value. Security usually a bank guarantee for up to 25% of the bond amount. The proper officer determines the surety / security based on the applicant's track record and the quantum at issue.
Final assessment under sub-s. (3)
FORM GST ASMT-07 within 6 months from communication of the provisional order. Extension by the Joint / Additional Commissioner for a further 6 months on recorded reasons; by the Commissioner for further period up to 4 years. Outer aggregate limit therefore — 6 months + 6 months + 4 years = approximately 5 years from the provisional order.
Interest under sub-s. (4)
Interest at 18% per annum under s. 50(1) on tax under final assessment but not paid on the due date of the original tax period. Interest runs from the first day after the due date till date of actual payment — irrespective of whether the differential is paid before or after the ASMT-07 final order. Practically: provisional payment defers tax but does not defer interest exposure on the eventual differential.
Refund under sub-s. (5)
Where final assessment determines refund (i.e., provisional payment exceeded final tax), refund is processed under s. 54 subject to s. 54(8) unjust enrichment test; interest under s. 56 on delayed refund (6% per annum after 60 days).
BLOCK 3 — COMMENTARY
STATUTORY ARCHITECTURE — A TIME-LIMITED ESCAPE VALVE FROM SELF-ASSESSMENT
Section 60 is the only departure from the s. 59 self-assessment regime that is initiated by the taxpayer (as opposed to the Department). It is designed for genuine inability — not unwillingness — to determine value or rate. The architecture reflects a careful balance: the taxpayer needs certainty before committing to a self-assessed return; the Department needs revenue protection during the period of uncertainty. The bond + surety mechanism under sub-s. (2) protects revenue against eventual short-payment; the 6-month + 6-month + 4-year hierarchical extension framework under sub-s. (3) provides procedural flexibility for complex cases; the s. 50 interest under sub-s. (4) ensures that the taxpayer does not benefit financially from the deferral; and the s. 56 interest under sub-s. (5) ensures that the Government does not benefit from a subsequent finding of over-payment.
Three architectural points are critical for practitioner orientation. First, s. 60 must be invoked pre-emptively — before the due date of the return for the affected period. Once the taxpayer has filed a self-assessed return under s. 59, the self-assessment has crystallised and the s. 60 route is no longer the appropriate remedy; the taxpayer must then engage with the s. 61 scrutiny process or seek a correction in a subsequent period (subject to Bharti Airtel constraints). Second, s. 60 is designed for genuine inability not deferral. Departmental practice has been to reserve s. 60 for narrow, well-articulated cases of uncertainty; applications that appear to be deferral strategies are rejected. Third, interest under sub-s. (4) is not avoidable. Provisional payment defers tax but creates an interest exposure on the eventual differential running from the original due date. This is the principal economic disincentive built into the section.
INTERFACE WITH SECTION 97 ADVANCE RULING — STRATEGIC CHOICE OF FORUM
A persistent practitioner question is whether s. 60 provisional assessment or s. 97 advance ruling is the appropriate route for resolving rate / valuation uncertainty. The two are complementary but distinct: (i) s. 97 AAR provides a binding determination on the question (between applicant and jurisdictional officer) — substantive certainty for ongoing and future transactions; (ii) s. 60 provisional assessment provides a procedural mechanism to pay tax pending substantive certainty — operational continuity without committing to a self-assessed position.
Where the question is purely classification or notification applicability and the transaction is recurring, the AAR route is generally preferable — the ruling resolves the underlying uncertainty. Where the question is fact-specific valuation and the transaction is one-off or evolving, provisional assessment may be the better route. In high-stakes cases practitioners frequently pursue both in parallel — provisional assessment for operational continuity while the AAR application progresses to a binding ruling. Once the AAR ruling issues, the provisional assessment is typically finalised on the basis of the ruling.
BOND AND SECURITY UNDER SUB-S. (2) — RULE 98 OPERATIONAL FRAMEWORK
Rule 98(3) of the CGST Rules prescribes that the proper officer may specify the bond amount and the surety / security based on the differential tax exposure. The operational practice is: (i) bond amount = differential between worst-case final tax and the proposed provisional tax for the period the provisional regime is expected to operate (typically multiplied by an estimate of monthly turnover for a 6-12 month buffer); (ii) security = bank guarantee for up to 25% of the bond amount; (iii) where the applicant has an established compliance track record, the proper officer may accept a lower security percentage; (iv) where the differential is very large (e.g., a 6% rate dispute on a Rs. 200 crore annual turnover would mean Rs. 12 crore exposure), the bond is sized appropriately and the security is institutionally significant.
Practitioners should engage proactively on the bond / security sizing — overly conservative officer estimates can lock up substantial working capital. Counter-proposals supported by historical compliance data, audited financials and the applicant's banking limits often succeed in negotiating reasonable terms. Where the security is operationally burdensome, the applicant may consider monetary release routes — pre-paying the worst-case tax through the cash ledger and seeking refund of any excess on final assessment.
TIMELINE DISCIPLINE — 90 DAYS + 6 MONTHS + EXTENSIONS
The timeline architecture under s. 60 is hierarchical: 90 days for the provisional order under sub-s. (1); 6 months for the final assessment under sub-s. (3); 6 months extension by Joint / Additional Commissioner on recorded sufficient cause; 4 years further extension by Commissioner. The cumulative outer limit is therefore approximately 5 years from the provisional order. In practice, most provisional assessments are finalised within the first 6-month window; extension to the 12-month total window is occasionally invoked; the Commissioner's 4-year extension is reserved for cases involving cross-jurisdictional inputs (e.g., GST Council clarifications pending), pending Supreme Court rulings, or particularly complex valuation methodologies. Practitioners should diary all the milestones from day 1 of the provisional order and track Commissioner-level extensions — bald or unreasoned extensions can be challenged on Wednesbury / reasoned-decision grounds.
INTEREST FRAMEWORK — SUB-S. (4) AND (5) — THE ECONOMIC ARCHITECTURE
The interest architecture has two limbs. Sub-s. (4) operates where the final assessment determines a higher tax than the provisional — the differential attracts interest at 18% per annum from the first day after the original due date till date of actual payment. The interest runs irrespective of whether the differential is paid before or after the ASMT-07 final order; pre-emptive payment of the worst-case provisional tax does not avoid interest if subsequently a higher final tax is determined.
Sub-s. (5) operates where the final assessment determines a lower tax than the provisional — the taxpayer is entitled to refund of the excess, with interest under s. 56 at 6% per annum from 60 days after the application date. The interest framework is asymmetric — 18% Departmental interest vs 6% taxpayer interest — reflecting the general indirect-tax design principle that revenue protection takes precedence over taxpayer time-value-of-money interests.
Practitioner strategy: where the worst-case tax exposure is significantly higher than the proposed provisional rate, consider monetary payment of the worst-case amount upfront to avoid the 18% interest accrual; on final assessment if the actual tax is lower, claim refund with 6% interest. The net financial outcome is typically better than paying the lower provisional rate and accruing 18% interest on the eventual differential.
INTERPRETATIVE POSITION — JUDICIAL TREATMENT AND DEPARTMENTAL PRACTICE
Section 60 has not generated significant Supreme Court or High Court jurisprudence in the GST regime to date. The substantive judicial position on provisional assessment in indirect-tax law has been developed under analogous pre-GST provisions — Rule 9B of the Central Excise Rules, 1944 / 2002 and s. 18 of the Customs Act, 1962. The principles consistently applied across these analogues are: (i) provisional assessment is for genuine, articulated inability — not deferral; (ii) timely finalisation is mandatory and the Department's failure to finalise within statutory windows is reviewable; (iii) interest on differential is statutory and automatic; (iv) refund of excess provisional payment carries interest from the prescribed date. Practitioners can rely on this pre-GST jurisprudence as persuasive in GST writ proceedings on s. 60 disputes.
The Departmental practice on s. 60 applications has been conservative — officers are trained to scrutinise applications carefully and reject those that appear to be deferral strategies. Acceptance rates are higher for: (i) bona-fide classification disputes pending AAR / clarification; (ii) related-party valuation cases with documented difficulty; (iii) contingent-consideration contracts. Acceptance rates are lower for: (i) applications filed after the return due date; (ii) bald applications without specific quantification of difficulty; (iii) cases where the difficulty is the taxpayer's own structuring choice.
DEPARTMENTAL VIEW (CBIC HANDBOOK OF GST LAW AND PROCEDURES, 2024 — CHAPTER IV)
The CBIC Handbook of GST Law and Procedures (DGGST, updated 30 September 2024) addresses provisional assessment in Chapter IV (Assessment, pp 101-114). The Handbook records the Departmental view that provisional assessment under s. 60 is ‘exceptional’ — to be invoked only where the taxpayer has a ‘genuine difficulty’ in determining value or rate, and not as a general deferral mechanism. The Handbook emphasises three operational features: (i) the 90-day window under sub-s. (1) is mandatory for the officer; (ii) the bond + security under sub-s. (2) must be sized to fully cover the worst-case differential; (iii) the 6-month finalisation under sub-s. (3) is the default norm — extensions are to be granted only on properly documented sufficient cause.
The Handbook expressly endorses the practice of routing classification disputes through AAR / AAAR (s. 97 / 100) where the issue is one of pure interpretation, and reserving s. 60 for cases involving fact-specific valuation or rate ambiguity that the AAR cannot easily resolve. The Department's stated view is that frequent or recurring use of s. 60 by a single taxpayer is itself a red flag — indicating either valuation / classification structuring issues or deferral strategy — and may trigger more intensive scrutiny under s. 65 (audit) or s. 61 (scrutiny of returns).
Practitioner alignment: file ASMT-01 with a comprehensive reasoned application — specify the precise legal question, the alternative interpretations, the proposed provisional rate / value with detailed calculations, the supporting documentation (contracts, commercial pricing data, prior period precedent), and the parallel measures (AAR application, industry-association engagement, GST Council clarification request). Engage proactively on bond / security sizing. Track the timeline carefully and follow up at month 5 of the 6-month final assessment window.

PROCEDURE — INVOKING AND OPERATING THE PROVISIONAL ASSESSMENT REGIME
Step 1: Diagnose the determinative difficulty
Document precisely the inability to determine value (s. 15 / Rule 27-31A application) or rate (HSN / SAC determination). Frame the question as a legal-interpretative question, not a commercial-decision question. Collate supporting commercial documentation — contracts, pricing histories, audit reports, prior period precedents, industry data.
Step 2: Evaluate alternative routes
Determine whether the question is amenable to s. 97 AAR application — if classification / notification applicability and the transaction is recurring, AAR is often the better primary route. Consider parallel pursuit — AAR for substantive certainty, s. 60 for operational continuity. Consider GST Council clarification request through industry association where the question is sector-wide.
Step 3: Frame the provisional proposal
Determine the proposed provisional rate / value with a detailed computation. The proposed provisional should be defensible — neither the most aggressive position nor a placeholder figure. The proposed provisional should be supported by a methodology that the Department can review and endorse with minimum modification.
Step 4: File FORM GST ASMT-01 on the common portal
Comprehensive application — statement of facts, legal question framed, alternative interpretations analysed, proposed provisional value / rate with computation, supporting documentation indexed and attached. Reference any pending AAR application or industry-clarification request.
Step 5: Respond to FORM GST ASMT-02 if issued
Within prescribed time (typically 15 days), respond in ASMT-03 with the additional information sought. Comprehensive and timely response is critical — the officer's bandwidth is limited and incomplete responses extend the 90-day clock.
Step 6: Receive ASMT-04 provisional assessment order
Within 90 days of application. Examine the order for: (i) the provisional rate / value granted; (ii) the bond / security conditions; (iii) the period covered by the provisional regime; (iv) any specific reporting requirements. Where the order is acceptable, proceed to bond execution; where it is unacceptable, file appeal under s. 107 within 3 months.
Step 7: Execute bond and furnish security in ASMT-05
Bond amount sized to cover the differential tax exposure; security typically bank guarantee for up to 25% of the bond amount. Engage with the officer on the sizing — overly conservative estimates lock up working capital. Where security is operationally burdensome, consider monetary payment of worst-case tax through cash ledger as an alternative.
Step 8: Discharge tax on provisional basis through regular returns
GSTR-3B for the covered periods at the provisional rate / value. Maintain a reconciliation register showing the provisional discharge vs the alternative computations (best-case and worst-case). Cross-reference with the bond amount to verify ongoing coverage.
Step 9: Cooperate with finalisation under sub-s. (3)
Respond promptly to FORM GST ASMT-06 finalisation notice; furnish documents called for; engage with the proper officer on methodology questions. Track the 6-month default window from the ASMT-04 order date; follow up at month 5.
Step 10: Engage with extensions where applicable
If Joint / Additional Commissioner proposes 6-month extension, examine the recorded sufficient cause — bald extensions are reviewable. If Commissioner proposes further extension up to 4 years, similar scrutiny. Where the extension is unreasoned, consider HC writ challenge on Wednesbury grounds.
Step 11: Receive ASMT-07 final assessment order and reconcile
On receipt, compute the differential (final vs provisional). Where final > provisional, pay the differential with s. 50 interest from the original due date through DRC-03; the bond will then be released. Where final < provisional, file refund application under s. 54 within 2 years from the ASMT-07 date with s. 56 interest claim.
Step 12: Apply for release of security in ASMT-08
Once the differential is paid (or refund processed), file ASMT-08 for security release. Receive ASMT-09 release order. Coordinate with banking partner for return of bank guarantee.

WORKED EXAMPLES
Example 60.1 — Classification difficulty: multi-purpose industrial chemical
Disputed HSN classification pending AAR — parallel s. 60 provisional assessment for operational continuity
Facts: M/s Polyphase Chemicals Pvt. Ltd. manufactures a multi-purpose industrial cleaning chemical that can be marketed for two distinct end-uses: heavy-duty industrial cleaning (Sl. No. X under HSN 3402 at 18%) and household / institutional cleaning (Sl. No. Y under HSN 3401 at 12% — concessional rate for household-use cleaning preparations). The company has historically classified at 18% (the higher rate) but the industry association has obtained a favourable Karnataka AAR ruling for a similar product at 12%; Polyphase wishes to migrate to 12% but the Department's local jurisdiction has not yet accepted the position. Polyphase's annual turnover from this product is Rs. 80 crore; the 6% rate differential is approximately Rs. 4.80 crore per annum.
Step 1: Step 1 — Diagnosis. The question is one of classification — purely interpretative — turning on the principal end-use and trade-parlance evidence. The product is the same; only the classification is uncertain.
Step 2: Step 2 — Alternative routes. Parallel AAR application filed in own State (with Karnataka AAR ruling cited as persuasive). Concurrent s. 60 provisional assessment to manage operational continuity during the 6-12 months the AAR application is expected to take.
Step 3: Step 3 — Provisional proposal. Polyphase proposes 12% as the provisional rate (consistent with Karnataka AAR; supported by trade-parlance evidence and industry-association studies). The Department may insist on 18% provisional (the higher rate) — negotiation on the bond / security framework becomes important.
Step 4: Step 4 — Filing. ASMT-01 with comprehensive product specifications, comparative HSN analysis, trade-parlance evidence, Karnataka AAR ruling, industry-association studies, and proposed 12% rate.
Step 5: Step 5 — ASMT-04 order. Officer grants 12% provisional subject to bond of Rs. 14.40 crore (3-year buffer at the 6% differential) with bank guarantee for 25% = Rs. 3.60 crore.
Step 6: Step 6 — Negotiation. Polyphase negotiates the bond down to Rs. 9.60 crore (2-year buffer) and the security down to 15% = Rs. 1.44 crore based on its 5-year compliance track record.
Step 7: Step 7 — Provisional discharge. GSTR-3B at 12% from the next month onwards. Reconciliation register: 12% (provisional) vs 18% (worst-case) tracked monthly. Interest exposure on the differential accrues at 18% per annum.
Step 8: Step 8 — AAR progresses. Own-State AAR concurs with Karnataka AAR — 12% classification confirmed.
Step 9: Step 9 — Final assessment. ASMT-07 finalises at 12%. No differential. Bond released; bank guarantee returned.
Result: Alternative outcome — if AAR / final assessment confirms 18%, Polyphase pays the differential (Rs. 4.80 crore per annum × period covered) with s. 50 interest at 18% per annum from the original due date. The interest cost is significant; this is why pre-emptive monetary payment of the worst-case tax is sometimes preferable to provisional 12% rate.
Example 60.2 — Valuation difficulty: related-party HO-BO supply
HO-BO supply where Rule 28 OMV is genuinely uncertain — provisional assessment with Rule 30 cost-plus methodology
M/s Cygnus Tech Services Pvt. Ltd. (head office in Karnataka) provides internally-developed software-as-a-service to its branch offices (BO) in 8 other States. Each BO is in an SEZ / EOU framework with restricted ITC (export-oriented operations). The Rule 28 second proviso (full-ITC recipient deemed OMV) is unavailable because the BO's ITC is restricted. Genuine OMV under Rule 28(a) is difficult — the software is uniquely developed for the group; there is no external commercial benchmark. The Rule 28 hierarchy progresses to Rule 30 (cost-plus 10%) as the residual methodology. Cygnus's annual HO-BO supply value (under proposed cost-plus 10%) is Rs. 50 crore; tax at 18% = Rs. 9 crore. The Department may seek to apply higher value under Rule 28(c) (90% of price to unrelated recipient) which would be operationally inapplicable in absence of unrelated recipients. Cygnus files ASMT-01 proposing Rule 30 cost-plus methodology as the provisional valuation basis, with detailed cost build-up (direct + indirect + overhead allocation), and trade-comparison data showing the 10% mark-up is reasonable. ASMT-04 issued granting cost-plus 10% as provisional value subject to bond of Rs. 5 crore (representing a 50% upward adjustment buffer) with bank guarantee for 20% = Rs. 1 crore. Provisional discharge proceeds; reconciliation register maintained. ASMT-07 final assessment finalises at cost-plus 10% on review of detailed cost data — no differential. Practitioner alignment — Rule 30 cost-plus is often the defensible provisional methodology for unique inter-group services; document the cost build-up rigorously; the bond / security framework is then sized to a reasonable upward-adjustment buffer rather than maximum hypothetical exposure.
Example 60.3 — Strategic monetary release vs bond / security
Cash payment of worst-case tax to avoid bond / security and interest accrual
M/s Vega Power Equipment manufactures equipment that has been classified at 18% but a recent industry-association study suggests 12% is supportable. Annual turnover Rs. 100 crore; 6% differential = Rs. 6 crore per annum. Vega is considering provisional assessment at 12% pending AAR. The bond + security framework would require Rs. 6 crore bond + Rs. 1.5 crore bank guarantee — operationally significant. Interest exposure on the differential if final assessment confirms 18% would be 18% per annum on Rs. 6 crore = Rs. 1.08 crore per annum. Alternative strategy — pay worst-case 18% through cash ledger via regular GSTR-3B; do not invoke s. 60 at all; pursue parallel AAR application. If AAR rules at 12%, file refund application under s. 54 for the excess paid; receive s. 56 interest at 6% per annum from 60 days post-application. Net financial outcome: Vega has paid Rs. 6 crore more than necessary for the AAR-pendency period (say 12 months); receives back Rs. 6 crore + 6% interest on receipt (say 4-6 months after refund application). Net interest cost — Rs. 6 crore × 6% × 18 months / 12 = Rs. 54 lakh. Compared to provisional 12% with worst-case 18% interest exposure: if AAR rules adversely, the s. 50 interest cost is Rs. 6 crore × 18% × 12 months / 12 = Rs. 1.08 crore. The break-even depends on the probability of favourable AAR. Where the practitioner assesses favourable AAR likelihood at > 50%, provisional 12% is preferable; where < 50%, monetary worst-case payment is preferable. Practitioner alignment — every s. 60 decision should be preceded by a quantitative scenario analysis weighing the bond / security cost, interest exposure under each outcome, and the probability assessment of AAR / final assessment outcome. The strategic choice often turns on this analysis.
Example 60.4 — Contingent consideration pending price determination
Supply with price subject to future event — provisional assessment with milestone-based finalisation
M/s Lyra Construction Pvt. Ltd. enters into a turnkey construction contract for Rs. 200 crore base price + variable bonus / penalty depending on completion timeline (bonus up to 10% of base for early completion; penalty up to 5% for delay). The contract is for 24 months. The taxable value under s. 15 is genuinely uncertain at the time of each supply (progress invoices) because the bonus / penalty cannot yet be determined. Lyra files ASMT-01 proposing the base price (Rs. 200 crore over the contract period) as the provisional value, with the bond sized to cover the maximum upward adjustment (10% bonus × Rs. 200 crore = Rs. 20 crore differential value × 18% = Rs. 3.60 crore tax differential). ASMT-04 grants base price as provisional; bond Rs. 4 crore with bank guarantee Rs. 1 crore. Lyra invoices progress payments at the provisional rate; tracks the contract completion milestones; reconciles on final completion. On contract completion, the actual bonus / penalty crystallises; if bonus achieved, Lyra issues supplementary invoice for the differential value with corresponding output tax and pays through DRC-03 with s. 50 interest from the original supply dates. The bond is then released after security retention period.
Example 60.5 — Timeline non-compliance and HC writ challenge
Commissioner's bald extension order — writ challenge on Wednesbury grounds
M/s Polaris Industries received ASMT-04 provisional order on 1 April 2024. The 6-month default window for finalisation expired on 1 October 2024. The Joint Commissioner issued a 6-month extension order on 28 September 2024 stating only ‘sufficient cause exists in view of the complexity of the matter’ — no specific reasons recorded. The further window expired on 1 April 2025. The Commissioner issued a further 2-year extension order on 25 March 2025 stating only ‘sufficient cause exists; matter is complex and Department needs more time’ — no specific reasons. Polaris files HC writ challenging the Commissioner's extension order on the ground that the recorded reasons are bald and unreasoned, falling foul of the Wednesbury principle and the s. 60(3) proviso's mandate of ‘reasons to be recorded in writing’. The writ seeks: (a) quashing of the extension order; (b) direction to finalise the provisional assessment within a time-bound window (typically 60 days); (c) interim protection from coercive recovery. Outcome — HCs across States have consistently quashed bald extension orders and directed time-bound finalisation. The substantive position on s. 60 timeline discipline is firm. Practitioner alignment — at every extension stage, demand the recorded reasons; where they are bald or boilerplate, preserve grounds and prepare HC writ; this discipline limits the Department's tendency to extend indefinitely.
PRACTITIONER PLANNING — STRATEGIC FRAMEWORK FOR s. 60 INVOCATION
• Diagnose first, file second. Before filing ASMT-01, conduct a substantive legal-interpretative analysis of the determinative difficulty. The question must be framable as a legal-interpretative question, not a commercial-decision question. Bald applications are routinely rejected.
• Evaluate the AAR route first. For classification / notification-applicability questions on recurring transactions, AAR is usually the better primary route. Consider parallel pursuit — AAR for substantive certainty, s. 60 for operational continuity.
• Quantify the bond / security cost vs the interest exposure. Conduct a scenario analysis: (i) cost of bond + security if provisional rate is granted; (ii) interest exposure at 18% if final assessment determines higher tax; (iii) alternative — monetary payment of worst-case tax with subsequent refund at 6% interest if final assessment favours taxpayer. The optimal strategy depends on the probability assessment of favourable final assessment.
• Time the application pre-emptively. ASMT-01 must be filed BEFORE the due date of return for the affected period. Once a self-assessed GSTR-3B is filed, the s. 60 route is no longer available for that period.
• Negotiate the bond / security framework. Engage proactively on bond amount and security percentage. Where the compliance track record is strong, lower security percentages (10-15% rather than 25%) are often achievable.
• Maintain comprehensive working papers throughout the provisional period. Reconciliation register showing provisional discharge vs best-case / worst-case alternatives; cross-reference with bond amount to verify ongoing coverage; monthly review with senior tax / finance leadership.
• Diarise all timeline milestones. ASMT-04 receipt date (day 0); 90-day window for officer's order (day 90); 6-month finalisation window (day 270); first extension by Joint / Additional Commissioner (day 270 + 6 months); Commissioner's further extension (up to 4 years). Follow up at month 5 of the 6-month finalisation window.
• Examine extension orders for recorded reasons. Bald or boilerplate extensions are reviewable on Wednesbury / reasoned-decision grounds. Where the recorded reasons are inadequate, preserve grounds and prepare HC writ.
• Engage with finalisation cooperatively. Comprehensive response to ASMT-06; cooperate with officer's methodology review; engage with cross-Departmental clarifications where applicable.
• Plan for both outcomes at finalisation. If final > provisional, prepare for DRC-03 differential payment with interest; if final < provisional, prepare refund application under s. 54 with s. 56 interest claim. Both paths require contemporaneous documentation.
LITIGATION DEFENCE — DISPUTES ARISING UNDER PROVISIONAL ASSESSMENT
• ASMT-01 rejection on procedural grounds. Defence — examine the rejection order for specific grounds; cure any procedural defect (e.g., insufficient documentation, missing reasoning) and re-file. The 90-day clock restarts.
• ASMT-04 order granting at less favourable terms than proposed (higher provisional rate / lower provisional value). Defence — appeal under s. 107 within 3 months with 10% pre-deposit; argue substantive merits of the proposed provisional approach.
• Excessive bond / security demand. Defence — engage with the proper officer with detailed compliance-track-record data, banking-limits information, and a sized differential analysis. Where the officer insists on unreasonable terms, the practical alternative is monetary payment of worst-case tax through cash ledger.
• Department's failure to finalise within 6-month default window. Defence — at month 5, file written representation seeking finalisation; at month 6, examine any extension order for recorded reasons. Bald extensions are reviewable.
• Commissioner's 4-year extension on inadequate grounds. Defence — HC writ challenge on Wednesbury grounds; seek time-bound finalisation direction; consider interim protection from coercive recovery.
• ASMT-07 final order at less favourable terms than provisional. Defence — appeal under s. 107 within 3 months; substantive merits arguments; alternative settlement under s. 73(5) / 74(5) framework where appropriate.
• Department's interest computation on differential. Defence — verify the start date (first day after due date of original tax period) and end date (date of actual payment); challenge any incorrect computation.
• Refund claim under sub-s. (5) denied on unjust enrichment grounds. Defence — invoke s. 54(8) carve-outs (zero-rated supplies, tax paid under wrong head, refund to person who bore incidence); CA-certificate / declaration as documentary support.
• Section 56 interest on refund of excess provisional payment denied. Defence — Saraf Natural Stone HC line — interest is automatic from 60 days post-application; HC writ for mandamus where Department denies.
• Bond release delay after final assessment differential paid. Defence — file ASMT-08 promptly; follow up with proper officer; HC writ where unreasonable delay.
