GST on Sale of Old Motor Vehicles: Margin Scheme, Capital Asset Disposal and the Legal Position under GST

 By CA Surekha Ahuja

Introduction

The sale of old motor vehicles under GST continues to be one of the most misunderstood areas of indirect taxation, not because the taxability is unclear, but because the valuation mechanism differs according to the nature of the transaction. A used vehicle may be sold by a dealer as part of trading activity, by a business as disposal of a capital asset, or by an individual as sale of a personal asset. Each category carries a different GST consequence.

The practical significance of this distinction is substantial. In one case, GST may apply only on the margin; in another, on the value after depreciation; and in some cases, no GST may arise at all. The issue has gained further attention after the Advance Ruling in Ponnusamy Thangaraj, where the Authority adopted a restrictive approach and subjected the entire sale consideration to GST.

The real question, therefore, is not whether GST applies, but on what value it applies.

The GST Framework on Sale of Old Motor Vehicles

GST law does not treat every sale of an old motor vehicle in the same manner. The valuation depends on the capacity in which the vehicle was held.

Where a person is engaged in the business of buying and selling used vehicles, the transaction falls within the margin scheme under Rule 32(5) of the CGST Rules. In such cases, GST is payable only on the difference between the selling price and the purchase price.

$\text{Value of Supply} = \text{Selling Price} - \text{Purchase Price}$

This reflects the GST principle that tax should be levied only on the value added by the dealer and not on the entire turnover.

A different treatment applies where the vehicle is held as a capital asset in business. Notification No. 08/2018-Central Tax (Rate) provides a separate valuation mechanism, recognising that such assets suffer depreciation over time and that GST should apply only on the value remaining after adjusting the depreciated base.

$\text{Value of Supply} = \text{Sale Consideration} - \text{Written Down Value (WDV)}$

This ensures that GST does not become a tax on capital recovery.

Where the vehicle is sold by an individual as a personal asset and not in the course or furtherance of business, the transaction generally remains outside the scope of GST.

The Real Distinction: Nature of Holding

The most important principle in determining GST on sale of old motor vehicles is that the law looks at the nature of holding and not merely the identity of the seller.

A dealer and a business may both sell an old car, but the GST treatment cannot be identical if the vehicle was held for entirely different commercial purposes.

Nature of Holding	Applicable Provision	Tax Base
Stock-in-trade	Rule 32(5)	Margin
Capital asset	Notification 08/2018	Sale value less WDV
Personal asset	Outside GST	Nil

This distinction forms the legal foundation of correct valuation.

AAR in Ponnusamy Thangaraj: Why It Matters

In Ponnusamy Thangaraj, the applicant sought to adopt margin-based valuation on sale of a used motor vehicle. The Authority denied the benefit on the ground that the applicant was not engaged in the business of buying and selling second-hand goods and therefore could not claim the margin mechanism.

As a result, GST was directed to be paid on the full sale consideration under Section 15(1).

The significance of this ruling lies not merely in its conclusion, but in its reasoning. By linking eligibility for concessional valuation to dealer status, the ruling has raised concerns for ordinary businesses disposing of capital assets.

Whether the Restrictive View is Correct

A closer reading of Notification No. 08/2018 shows that it does not require the supplier to be a dealer in second-hand goods. Its focus is on the asset itself and the conditions attached to its disposal.

Broadly, the conditions revolve around:

• the vehicle being an old or used motor vehicle
• the supplier being a registered person
• non-availment of input tax credit
• identifiable depreciation where applicable

The notification addresses a separate commercial reality from Rule 32(5). One governs trading inventory; the other governs business asset disposal.

Treating both under the same interpretational lens defeats the legislative distinction.

Further, as a settled principle of tax interpretation, a specific valuation mechanism prevails over a general valuation rule. Therefore, where Notification No. 08/2018 applies, Section 15(1) should not become the default basis.

Practical Compliance and Advisory Perspective

For taxpayers, the legal position alone is not enough. The sustainability of the position depends on documentation.

Businesses intending to apply Notification No. 08/2018 should ensure:

• the vehicle is properly reflected in the fixed asset register
• depreciation is consistently claimed under income tax law
• no input tax credit has been availed on purchase
• sale documentation clearly records the valuation basis
• accounting treatment remains consistent across financial and tax records

In practical scrutiny, disputes often arise not because the law is weak, but because the evidence is incomplete.

Where classification and records are strong, the defence under Notification No. 08/2018 remains significantly stronger.

Where they are weak, the Department may seek to apply Section 15(1) and tax the full consideration.

Conclusion

The GST treatment on sale of old motor vehicles is fundamentally driven by the nature of holding and not merely by the act of sale. A dealer selling used inventory and a business disposing of a depreciated capital asset operate under different commercial and legal frameworks and therefore cannot be subjected to the same valuation principle.

Rule 32(5) and Notification No. 08/2018 are distinct statutory mechanisms designed for distinct situations. The former taxes trading margin; the latter taxes value over depreciated cost.

The ruling in Ponnusamy Thangaraj may influence departmental scrutiny, but it does not alter the statutory framework. For taxpayers, the key lies in correct classification, robust documentation, and consistent accounting treatment.

Under GST, the question is rarely whether tax is payable. The real question is on what value it is payable—and in the sale of old motor vehicles, that distinction makes all the difference.

GST Refund Under GST: Rejection, Scrutiny, Appeal Procedure, Interest on Delayed Refund and Litigation Strategy - Part II

By CA Surekha Ahuja

Introduction: When GST Refund Becomes a Defence Process

GST refund is often perceived as a procedural filing exercise. In reality, it becomes a structured legal and data verification process once the application enters departmental scrutiny.

Part I deals with eligibility and creation of a valid refund claim. Part II deals with what happens after filing and how the claim is defended through scrutiny, objections, adjudication, appeal and final settlement.

At this stage, refund is no longer a compliance submission. It becomes a document driven, reconciliation intensive and legally examined process.

The refund lifecycle typically moves through the following stages

Filing of refund application in RFD 01
Acknowledgment and initial processing in RFD 02
Deficiency memo, if any, in RFD 03
Show cause notice in RFD 08
Reply submission in RFD 09
Order of sanction or rejection
Appeal under Section 107 where required
Interest computation and final settlement

A well prepared response at scrutiny stage often determines whether the matter ends at the department level or proceeds into litigation.

Unjust Enrichment: The Core Legal Principle

The doctrine of unjust enrichment ensures that refund is granted only where the burden of tax has not been passed on to another person.

Under Section 54 of the CGST Act, refund is not admissible if it results in unjust enrichment, except in specified situations.

Applicability Understanding

Export and zero rated supplies under LUT are generally outside the scope of unjust enrichment
Refund of input tax credit is generally not subject to unjust enrichment but requires proper reconciliation
Excess balance in electronic cash ledger is generally not subject to unjust enrichment in practical application
Refund of excess tax paid may be subject to unjust enrichment based on factual circumstances

Core Principle

Refund is allowed only where the taxpayer has actually borne the tax burden.

Where tax is recovered from the recipient, refund may be credited to the Consumer Welfare Fund.

Proper certification and documentary evidence play a decisive role in establishing this position.

Departmental Scrutiny: The Real Examination Stage

After filing of RFD 01 and issuance of RFD 02 acknowledgment, the refund application enters scrutiny.

Scrutiny is not subjective in nature. It is primarily a data matching and reconciliation exercise.

Key Verification Areas

Turnover comparison between GSTR 1 and books of accounts
Tax liability matching between GSTR 3B and electronic liability ledger
Input tax credit reconciliation with GSTR 2B
Export validation through shipping bills and customs data
Foreign exchange realisation through FIRC or BRC
Refund computation accuracy and formula validation
Completeness of supporting documents

Most refund disputes arise due to mismatches in data rather than interpretation of law.

Deficiency Memo versus Show Cause Notice

Two distinct procedural tools are used by the department.

A deficiency memo under RFD 03 indicates that the application is incomplete or defective and requires correction or fresh filing.

A show cause notice under RFD 08 indicates proposed rejection of refund after preliminary examination.

Key Distinction

Deficiency memo is procedural in nature
Show cause notice is substantive in nature

Deficiency memo leads to rectification or re filing
Show cause notice requires legal and factual defence

Understanding this distinction is critical for deciding response strategy.

Show Cause Notice Response Strategy

A show cause notice is a critical stage in refund proceedings as it represents the department’s intention to reject the claim.

A structured response under RFD 09 should include

Legal basis of refund eligibility under relevant provisions
Factual reconciliation of GST returns and books of accounts
Detailed computation of refund amount
Documentary evidence supporting each claim component
Specific clarification against each objection raised
Judicial or interpretational support where relevant

A strong and well structured response at this stage often determines the final outcome without further escalation.

Common Grounds for Refund Rejection

Refund rejections generally arise from predictable and recurring issues.

Typical Grounds

Mismatch between GST returns and accounting records
Input tax credit differences between books and GSTR 2B
Incomplete documentation or missing evidence
Errors in refund formula or computation method
Inclusion of ineligible input tax credit
Delay beyond statutory limitation period
Incorrect classification of refund category

Defence Approach

Reconciliation statements for data mismatch
GSTR 2B mapping for ITC differences
Supplementary documentation for missing records
Revised computation workings for formula errors
Limitation analysis based on legal interpretation

Each issue requires factual correction supported by documentary evidence.

Withholding of Refund by Department

Refund may be withheld in specific statutory situations.

Common grounds include pending GST returns, outstanding tax demands, ongoing investigation or protection of revenue interest.

Practical Response Strategy

File pending returns immediately
Seek stay on disputed demand where applicable
Challenge arbitrary withholding through appropriate legal remedy where required

Appeal Against Refund Rejection

Refund rejection orders are appealable under Section 107 of the CGST Act.

Key Features

Appeal is filed in Form APL 01
Time limit is three months from the date of order
Condonation of one additional month is available in appropriate cases
Appeal lies before the First Appellate Authority

Timely filing is critical as delay may weaken procedural position and evidentiary strength.

Pre Deposit Requirement

In cases involving only refund rejection without tax demand, pre deposit is generally not applicable.

Where refund rejection is linked with demand of tax, pre deposit of prescribed percentage of disputed tax may be required.

Each case must be evaluated based on the operative portion of the order rather than its title.

Appeal versus Writ Strategy

Selection of remedy is a strategic decision.

Appeal is appropriate in cases involving factual disputes or computational issues.

Writ jurisdiction is appropriate where there is violation of natural justice, arbitrary withholding or unreasonable delay beyond statutory timelines.

Incorrect remedy selection may lead to procedural delays and prolonged blockage of refund.

Interest on Delayed Refund

Section 56 of the CGST Act provides for interest on delayed refund where refund is not sanctioned within sixty days from the date of acknowledgment in Form RFD 02.

Interest is payable from the expiry of statutory period until the date of actual refund.

Illustration

Acknowledgment date 1 May 2026
Statutory due date 30 June 2026
Actual refund date 20 August 2026

Interest is payable for the intervening period of delay.

Interest claim should always be computed and monitored as part of refund tracking.

Refund as an Audit Ready Exercise

A refund claim should be prepared with the assumption that it may be subject to audit verification.

Key Readiness Checks

Turnover reconciliation completed and validated
Input tax credit fully reconciled with GSTR 2B
Export and supporting documentation complete
Computation workings properly structured
Limitation period compliance verified

Any gap in these areas increases litigation risk significantly.

Refund Risk Management Framework

Refund management should be treated as a continuous compliance process.

Recommended Monitoring Structure

Monthly refund status tracking
Monthly reconciliation of turnover and exports
Regular ITC validation against GSTR 2B
Periodic review of cash ledger balances
Continuous monitoring of limitation periods

Consistent monitoring significantly reduces disputes and rejection probability.

Professional Refund File Structure

A well organised refund file strengthens defence at every stage.

Ideal Structure

Legal eligibility note under Section 54
Limitation computation sheet
Refund calculation workings
Reconciliation statements with GST returns
Supporting documentary evidence
Copy of departmental communications
Show cause notice and reply records
Appeal documentation where applicable

Proper documentation often resolves disputes at the scrutiny stage itself.

Common Practical Mistakes in Refund Cases

Frequent errors leading to rejection include ignoring show cause notices, submitting incomplete replies, failure to reconcile data, delay in filing appeals and not claiming statutory interest.

These errors are procedural but have significant financial consequences.

Final Conclusion

GST refund is not a single stage compliance process. It is a structured legal lifecycle involving filing, scrutiny, adjudication, appeal and final settlement.

The success of a refund claim depends on four critical pillars

Accuracy of data at the time of filing
Strength of reconciliation during scrutiny
Quality of response during adjudication
Strategic consistency during appeal, if required

The governing principle remains absolute.

A refund is not complete when it is filed. It is complete only when it is successfully received and sustained.

The difference between filing and realization lies in preparation, documentation discipline, timely response and sustained professional execution.

GST Refund Under GST (2026): Complete Guide on Eligibility, Limitation, Filing Process, Documentation & Refund Calculation (Part I)

By CA Surekha Ahuja

GST Refund: A Statutory Right, Realised Through Procedural Discipline

The GST refund mechanism is founded on a settled principle of indirect taxation:

Tax should not remain embedded in business cost where the law permits adjustment, neutrality or refund.

Where tax remains unutilized, is paid in excess, or becomes refundable under law, the taxpayer is entitled to claim refund.

In practical terms, refund situations commonly arise in:

• exports and zero-rated supplies,
• inverted duty structures,
• excess balance in electronic cash ledger,
• tax paid under the wrong tax head,
• excess tax payments, and
• consequential appellate relief.

However, practical experience consistently shows that refund realization is rarely lost because of absence of legal entitlement.

It is usually lost because of procedural failure.

The Real Reasons Refund Claims Fail

Risk Area	Practical Consequence
Wrong refund category	Wrong form, wrong documents, wrong computation
Limitation failure	Claim becomes time-barred
Reconciliation mismatch	Notice, objection, rejection
Incomplete documents	Deficiency memo
Incorrect computation	Reduced or rejected refund
Weak internal review	Delayed realization

Professional principle:
GST refund is not merely a filing process.

It is a structured statutory recovery process.

And like every recovery process, preparation determines realization.

Legal Framework Governing GST Refunds

The refund mechanism under GST is governed by Sections 54 to 56 of the CGST Act, 2017 read with Rules 89 to 96 of the CGST Rules.

These provisions together regulate eligibility, procedure, computation and sanction.

Core Legal Structure

Provision	Scope
Section 54	Refund of tax, interest, penalty, fee or other amount
Section 56	Interest on delayed refund
Section 77	Refund of tax paid under wrong tax head
Rule 89	Application and computation
Rule 90	Acknowledgment and deficiency
Rule 91	Provisional refund
Rule 92	Sanction or rejection
Rule 93	Re-credit on rejection
Rule 96	Export refund mechanism

Professional Interpretation

Legal Layer	Practical Function
Section 54	Creates the statutory right
Rules 89–96	Prescribe the procedural route
Documentation & Reconciliation	Protect admissibility

A strong refund claim requires all three.

Types of GST Refund: Correct Classification is the Foundation

Refund under GST is category-driven.

Classification is not a technical formality.

It determines:

• limitation,
• computation formula,
• documentary requirement,
• procedural route.

Refund Category Matrix

Refund Type	Typical Scenario	Primary Risk Area
Export under LUT	Export without tax payment	LUT validity / realization
Export with IGST	Tax paid on exports	Shipping bill mismatch
Supply to SEZ	Zero-rated supply	Endorsement deficiency
Inverted duty structure	Input tax higher than output tax	Formula error
Excess cash ledger	Excess tax deposited	Ledger mismatch
Wrong tax paid	Wrong tax head used	Delay in correction
Excess tax paid	Tax deposited in excess	Unjust enrichment issue

Professional rule:
Correct classification determines the refund strategy.

Refund Eligibility vs Non-Eligibility

Not every payment or credit under GST qualifies for refund.

Eligibility must be examined before filing.

Eligibility Matrix

Particulars	Refund Position	Practical Note
Export under LUT	Eligible	Subject to realization
Export with IGST	Eligible	Subject to customs integration
Inverted ITC accumulation	Eligible	Subject to statutory formula
Excess cash ledger	Eligible	Direct recovery mechanism
Wrong tax payment	Eligible	Section 77 protection
Blocked ITC under Section 17(5)	Not eligible	Statutory restriction
Ineligible ITC	Not eligible	No refund permissible
Voluntary penalty payment	Usually not eligible	Depends on legal facts

Professional principle:
Refund eligibility begins only where tax admissibility survives.

Limitation Period: The First Professional Check

A refund claim may be legally valid and yet fail completely if filed late.

The law prescribes:

Refund application must be filed within two years from the relevant date.

This is substantive compliance.

Not procedural.

A valid claim filed beyond limitation is a failed claim.

That makes limitation the first professional checkpoint.

Not the final one.

Relevant Date: The Starting Point of Limitation

The refund clock does not begin uniformly.

It differs according to the refund category.

That distinction is legally decisive.

Relevant Date Matrix

Refund Type	Relevant Date
Export of goods	Shipping bill date
Export of services	Date of receipt of foreign exchange
Inverted duty refund	Due date of relevant return
Excess tax paid	Date of tax payment
Wrong tax paid	Date of payment of correct tax

Practical Illustration

Particular	Date
Shipping bill date	15 April 2024
Last date for refund	14 April 2026

Not invoice date.

Not return filing date.

Professional reality:

Wrong identification of relevant date is one of the costliest refund mistakes.

Why April 2026 Is Strategically Important for Refund Planning

April is the most critical month for refund review.

Because it marks:

• financial year closure,
• annual reconciliations,
• final visibility of accumulated ITC,
• pending refund identification,
• limitation-sensitive claim review.

For FY 2025–26, April 2026 should be treated as a structured refund audit month.

It is the month where businesses should identify blocked funds and recoverable tax positions.

April 2026 Refund Audit Checklist

Every business should conduct a structured refund review.

Refund Review Matrix

Review Area	Purpose
Export invoice review	Identify missed claims
ITC accumulation review	Determine refund eligibility
LUT validity review	Protect export continuity
Shipping bill reconciliation	Prevent export refund blockage
FIRC/BRC verification	Validate export realization
Cash ledger review	Recover idle deposits
Pending ARN review	Expedite pending claims
Limitation tracker	Prevent expiry of claims

This single review can protect substantial working capital.

Refund Filing Process: The Correct Professional Workflow

Refund filing should begin with internal review—not with the portal.

A professional filing sequence is essential.

Filing Workflow Matrix

Stage	Action	Objective
Stage 1	Eligibility review	Confirm admissibility
Stage 2	Category determination	Select correct refund type
Stage 3	Limitation review	Protect filing period
Stage 4	Reconciliation	Ensure data consistency
Stage 5	Documentation	Compile evidence
Stage 6	Computation	Determine admissible amount
Stage 7	Portal filing (RFD-01)	Formal claim submission

Portal path:

Services → Refunds → Application for Refund

Always preserve:

• ARN
• acknowledgment
• supporting worksheets

Reconciliation Before Filing: Non-Negotiable

Most refund disputes are not legal disputes.

They are reconciliation disputes.

A refund application should never be filed without internal matching.

Mandatory Reconciliation Matrix

Reconciliation Area	Objective
Books vs GSTR-1	Turnover verification
Books vs GSTR-3B	Tax verification
Purchase register vs GSTR-2B	ITC verification
Export invoices vs shipping bills	Export verification
FIRC/BRC vs invoices	Realization verification

Professional truth:

Reconciliation protects refund admissibility.

Refund Forms and Their Practical Importance

Every refund application moves through procedural stages.

Understanding the forms improves compliance discipline.

Refund Form Matrix

Form	Purpose
RFD-01	Main refund application
RFD-02	Acknowledgment
RFD-03	Deficiency memo
RFD-04	Provisional refund
RFD-05	Payment order
RFD-06	Final sanction or rejection

Each form represents a procedural stage.

Each stage requires professional response.

Deficiency Memo (RFD-03): A Hidden Limitation Risk

A deficiency memo means the refund application is incomplete.

Processing stops.

Fresh filing becomes necessary.

This creates limitation exposure.

Practical Illustration

Event	Date
Original filing	28 March 2026
Deficiency memo issued	8 April 2026
Limitation expiry	31 March 2026

Fresh filing after limitation may be contested.

Professional lesson:
Incomplete filing can be more dangerous than delayed filing.

Refund Computation: Accuracy Determines Recovery

Refund under GST is formula-based.

Incorrect computation can reduce or destroy entitlement.

Accuracy is non-negotiable.

Export Refund Computation Formula

Refund = (Zero-rated turnover ÷ Adjusted turnover) × Net ITC

Practical Illustration

Particulars	Amount
Export turnover	₹80 lakh
Total turnover	₹100 lakh
Net ITC	₹12 lakh
Refund admissible	₹9.60 lakh

Key professional point:
Net ITC means eligible ITC after reversals.

Not gross ITC.

Inverted Duty Refund Computation

Formula

Refund = (Turnover of inverted supplies × Net ITC ÷ Adjusted turnover) − tax payable

Practical Illustration

Particulars	Amount
Inverted turnover	₹50 lakh
Net ITC	₹8 lakh
Adjusted turnover	₹80 lakh
Tax payable	₹2 lakh
Refund admissible	₹3 lakh

Computation Risk Matrix

Error	Impact
Gross ITC considered	Excess claim
Blocked ITC included	Rejection
Wrong turnover base	Reduced refund

Professional principle:
Only eligible net ITC must enter the formula.

Documents Required: Category-Wise Checklist

Documentation determines defensibility.

A strong claim without documents is a weak claim.

Documentation Matrix

Refund Type	Core Documents
Export of goods	Invoices, LUT, shipping bills, returns
Export of services	Invoices, LUT, FIRC/BRC, agreements
Inverted duty refund	Purchase register, sales register, ITC ledger
Excess cash ledger	Ledger extract, challan/payment proof

Documentation must support both facts and computation.

Top Practical Mistakes at the Filing Stage

Most refund failures arise from avoidable procedural mistakes.

Error Matrix

Mistake	Consequence
Wrong refund category	Technical rejection
Wrong relevant date	Time-barred claim
Formula error	Reduced refund
Ineligible ITC included	Partial rejection
Return mismatch	Notice/query
Missing documents	Deficiency memo
Weak reconciliation	Refund delay

Most refund failures are procedural.

Not substantive.

Professional Pre-Filing Checklist

Before filing any refund claim, every professional should validate the following:

Quick Validation Matrix

Checkpoint	Status
Refund category correctly identified	Yes
Limitation period protected	Yes
Returns reconciled	Yes
ITC defensible	Yes
Documents complete	Yes
Formula correctly applied	Yes

If any answer is uncertain, filing should wait.

Correction before filing is easier than defence after filing.

Professional Conclusion 
GST refund is not merely a claim for money.

It is the recovery of blocked working capital through disciplined statutory compliance.

A sustainable refund claim depends on:

Refund Foundation Matrix

Core Element	Importance
Correct classification	Legal foundation
Limitation protection	Time protection
Reconciliation accuracy	Data integrity
Documentation strength	Evidence support
Computation correctness	Financial accuracy

The strongest refund claims are not prepared at the time of filing.

They are prepared before filing.

That preparation determines recovery.

In GST refunds, entitlement creates the right, but preparation secures the recovery.

In Part II, we will cover the more critical litigation side of GST refunds: departmental objections, show cause notices, rejection, appeals, writ remedies, interest on delayed refunds and litigation strategy.

TDS / TCS Compliance for FY 2026–27 (AY 2027–28): New Forms, Rates, Due Dates & Transition Risks

A Practical Compliance Note under the Income-tax Act, 2025

By CA Surekha Ahuja

FY 2026–27 marks the first full compliance cycle under the revised TDS/TCS framework of the Income-tax Act, 2025.

This is not merely a renumbering of sections. The law has restructured the operational compliance architecture itself—returns, declarations, certificates, remittance reporting and special challan-cum-statements.

For deductors, this creates a new compliance reality:

Procedural accuracy is now as important as tax deduction accuracy.

A correct deduction with wrong reporting, wrong form, wrong challan or wrong certificate can still result in defective compliance.

And defective compliance may trigger:

• interest liability
• late filing fee
• penalty exposure
• tax credit mismatch
• notices and disputes

This note captures the key practical changes every deductor must track for FY 2026–27.

What Has Changed? (Quick Form Mapping)

Compliance Area	Old Form	New Form
Declaration (non-deduction)	15G / 15H	121
Salary TDS Return	24Q	138
Resident TDS Return	26Q	140
Non-resident TDS Return	27Q	144
TCS Return	27EQ	143
Salary Certificate	16	130
Non-salary Certificate	16A	131
Property / Rent / Specified Payment Certificate	16B / 16C / 16D	132
TCS Certificate	27D	133
Foreign Remittance Declaration	15CA	145
Foreign Remittance CA Certificate	15CB	146
Special Challan-cum-Statement	26QB / 26QC / 26QD	141

Biggest transition risk: Use of old forms in the new compliance year.

Core TDS Rates (High-Frequency Transactions)

Nature of Payment	Section	Rate	Threshold
Salary	392	Slab rates	Taxable salary
Interest (bank/deposits)	393(1)T5	10%	₹50,000 / ₹1 lakh
Rent	393(1)T2(i)	2%	₹50,000 per month
Contractor Payments	393(1)T6(i)	1% / 2%	₹30,000 / ₹1 lakh
Professional Fees	393(1)T6(iii)(a)	10%	₹50,000
Technical Fees	393(1)T6(iii)(b)	2%	₹50,000
Property Purchase	393(1)T3(i)	1%	₹50 lakh
Purchase of Goods	393(1)T8(ii)	0.1%	₹50 lakh
Virtual Digital Assets (VDA)	393(1)T8(vi)	1%	₹10,000 / ₹50,000

Practical caution: Wrong classification remains one of the biggest causes of short deduction disputes.

Declaration Forms (Form 121 replacing Form 15G / 15H)

Form 121 now replaces Form 15G and Form 15H.

Rule	Compliance Impact
Obtained before payment/credit	Valid non-deduction possible
Obtained after deduction	No retrospective relief

Practical caution: Late declaration does not regularise an earlier deduction default.

Quarterly Returns & Due Dates

Nature	New Form	Due Date
Salary TDS	138	31 July / 31 October / 31 January / 31 May
Resident Payments	140	Same
Non-resident Payments	144	Same
TCS	143	Same

Watchpoint: Q4 due date (31 May) remains the most frequently missed deadline.

Form 141 (Special Compliance Cases)

Separate from quarterly returns.

Transaction	Due Date
Property Purchase	30 days from month-end
Rent by specified persons	30 days from month-end
Contractor / Professional payments by specified persons	30 days from month-end
VDA Transfer	30 days from month-end

Important: Default in Form 141 is an independent compliance default.

Certificates (New Form Mapping)

Purpose	New Form	Due Date
Salary Certificate	130	15 June
Non-salary Certificate	131	15 days after return due date
Property / Rent / Specified Payments	132	15 days after Form 141 due date
TCS Certificate	133	15 days after TCS return due date

Practical caution: Wrong certificate issuance may affect deductee credit.

Foreign Remittance Compliance

Purpose	New Form	Timing
Remittance Declaration	145	Before remittance
CA Certificate	146	Before remittance (where applicable)

Banks may not process remittance without proper compliance.

Transitional Compliance Alert (April–May 2026)

This is the most critical transition phase.

For a brief period, both compliance systems will operate simultaneously.

Deduction Period	Applicable Framework	Due Date
March 2026 deduction	Earlier framework (FY 2025–26)	30 April 2026
April 2026 deduction	New framework (FY 2026–27)	7 May 2026

This creates a dual-compliance window.

High-risk transition errors:

❌ Depositing March deductions under new framework
❌ Depositing April deductions under old framework
❌ Wrong challan tagging
❌ ERP/payroll masters not updated from 1 April 2026
❌ Wrong form mapping in Q1 filings

Practical action:

✔ Close March reconciliation before 30 April
✔ Update payroll/TDS masters from 1 April
✔ Segregate old-year and new-year challans
✔ Validate new form mapping before first April deduction

Practical note: The first defaults under the new law may arise from transition confusion—not tax failure.

Payment Due Dates

Compliance	Due Date
Monthly TDS/TCS (April–February)	7th of next month
March deduction	30 April
Form 141 cases	30 days from month-end

Financial Cost of Non-Compliance

Default	Exposure
Failure to deduct	1% per month or part thereof
Failure to deposit	1.5% per month or part thereof
Late return filing	₹200 per day (subject to statutory limits)

Common correction areas:

• Wrong PAN
• Wrong section code
• Wrong financial year
• Wrong deductee mapping

Practical point: Correct errors before return processing and certificate issuance.

Key Compliance Traps in FY 2026–27

❌ Using old forms
❌ Missing Form 141 timelines
❌ Late Form 121 collection
❌ Wrong PAN reporting
❌ Wrong challan mapping
❌ Wrong certificate issuance
❌ Missing Q4 return deadline
❌ Transition-period confusion

Under the new law, TDS/TCS defaults will increasingly arise not from failure to deduct—but from failure to comply correctly.

And in the first year of transition, the biggest exposure may not be tax computation—

it may be compliance migration failure.

In FY 2026–27, procedural discipline will be the first line of tax defence.
