Form 48 Replaces Form 3CEB: What Transfer Pricing Teams Must Document

There is a familiar transfer pricing ritual in many Indian subsidiaries of multinational groups. The finance team closes the books, the statutory audit gets completed, the tax audit starts, and somewhere around the compliance deadline someone asks: “Do we also need to prepare the TP study?”

The honest answer has always been yes, at least where the prescribed documentation requirements apply. But in practice, many taxpayers treated the transfer pricing study like a fire extinguisher: technically required, but brought out only when there was smoke, litigation, or a specific notice from the tax department.

That approach may soon become very uncomfortable.

The Income-tax Act, 2025 and the Income-tax Rules, 2026 are now in force from 1 April 2026, and the reporting form moves from the old Form 3CEB to the new Form 48. The Income-tax Rules, 2026 were notified by CBDT on 20 March 2026. What concerns me is not the form itself. It is that Form 48 asks for the record behind the numbers: the comparables, the margin range, the aggregation logic, and the confirmation that the prescribed file exists. The analysis that used to sit quietly inside the local file is now requested at the reporting stage.

This is why the industry should not wait until FY 2026–27 to change its behaviour. Even though Form 48 will apply to the new tax year framework, the discipline required to file it properly must begin now, while closing and documenting FY 2025–26.

The old world: Form 3CEB as the "minimum compliance" document

Under the Income-tax Act, 1961, every person entering into an international transaction or specified domestic transaction was required to obtain and furnish an accountant’s report in Form 3CEB under section 92E. The old form required details such as the list of associated enterprises, nature of relationship, broad transaction categories, amounts as per books, amounts computed with reference to arm’s length price, and the method used for determining arm’s length price.

This was never meant to replace the transfer pricing study. The accountant’s report was a certification and disclosure mechanism. The deeper analysis belonged to the documentation framework under section 92D and Rule 10D: functions performed, assets used, risks assumed, comparables, economic analysis, method selection, assumptions, pricing policies and adjustments. The Income Tax Department’s transfer pricing guidance states that every person entering into international transactions or specified domestic transactions must keep prescribed documentation. Rule 10D covered the group profile, the business description, the transaction terms, the FAR analysis, the comparability analysis, the method and the actual working for arm’s length price.

Yet, in practice, many businesses and even some advisers operated in a grey zone. They would file Form 3CEB, disclose the transaction values, mention a method, and then keep the detailed TP study pending unless there was scrutiny, a TPO reference, or a management requirement. It was a little like submitting the cover page of a thesis and promising that the research exists somewhere in the background.

The law did not endorse that approach. But the old reporting format sometimes allowed it to survive.

The new world: Form 48 brings the TP study closer to the filing itself

Form 48 is the accountant’s report under section 172 of the Income-tax Act, 2025. The official FAQ maps Form 3CEB under the Income-tax Rules, 1962 to Form 48 under the Income-tax Rules, 2026, section 92E to section 172, and Rule 10E to Rule 85. It also confirms that Form 48 is mandatory for every person who has entered into an international transaction and/or specified domestic transaction during the tax year. Section 171, which deals with keeping the prescribed information and documents, is where the study itself sits.

The structure shows where the pressure now sits. Form 48 has six parts. Part A takes the assessee’s details and Part B the aggregate transaction amounts, which the form auto-populates. Parts C and D take the international and deemed international transactions and the specified domestic transactions. Part E works out the arm’s length price and any adjustment. Part F asks about the documentation, where the specified conditions are met.

That is the real shift. Form 48 does not stop at what you transacted and which method you used. It wants the trail behind the position: the associated enterprise, the relationship, the transaction ID, any aggregation, the method, the number of comparables, the margins, whether the result sits inside the range, whether an adjustment follows, and whether the prescribed documents were kept.

Part E is the wake-up call: benchmarking moves into the form

The most important change in behaviour sits in Part E. This section asks how the arm’s length price was determined. It asks whether closely linked transactions were aggregated, which method was chosen as the most appropriate, how many comparables were used, and what the mean, median, 35th and 65th percentile results were. Every one of those answers has to come from a file that already exists. The form summarises the work. It does not replace it.

For a taxpayer on TNMM, Part E goes into the mechanics. It asks for the base used for the net profit margin, such as costs incurred, sales effected, assets employed or another base, the amount of that base as per the books, the margin realised, the comparable margin before and after adjustments, and whether section 165 of the Income-tax Act, 2025 requires an adjustment. A cost base assembled after the year end answers none of this well.

This changes the compliance conversation.

Historically, a captive service provider might say: “We are cost plus 15%, our group policy says so, and we will prepare the study later.” Under the Form 48 environment, that is a weak operating model. If the form itself asks for the computation logic, the number of comparables, margin range, adjustment and ALP outcome, then the benchmarking analysis cannot be an afterthought. It must exist before filing, and in many cases, it should exist before book closure.

Part F ends the "prepare documentation if selected" mindset

Part F carries the same weight. It opens where the aggregate value of international transactions is above ₹1 crore, or where specified domestic transactions are reported. The assessee states whether the conditions for not keeping fresh documents are met. If they are not, the assessee states whether the information and documents prescribed under section 171 have in fact been kept. The accountant then certifies that proper information and documentation have been kept, so far as appears from examination of the records.

This is not a small checkbox. It puts the documentation question squarely inside the reporting workflow.

Rule 84 of the Income-tax Rules, 2026 sets out what that file must hold. For every international transaction and every specified domestic transaction, the record has to cover the ownership structure, the group profile, the business and industry description, the terms of the transaction, the FAR analysis, the economic and market analyses, the uncontrolled transactions, the comparability analysis, the method, the actual working for arm’s length price, the assumptions, the pricing policies and the adjustments. Read as a list, that is a working file, not a set of disclosures.

Rule 84 also keeps the idea of contemporaneous documentation. The information and documents should, as far as possible, be contemporaneous, and they should exist on the specified date. They must then be kept for nine years from the end of the tax year. So contemporaneous documentation is a date test as much as a filing test. A study built after the specified date sits awkwardly against that requirement, however good the analysis.

So, the new regime is not saying something completely new. It is making the old expectation harder to ignore.

Why FY 2025–26 matters, even though Form 48 applies from FY 2026–27

A common reaction will be: “Form 48 applies from Tax Year 2026–27. Why should we change the FY 2025–26 process?”

Because process maturity cannot be switched on like a portal utility.

The transition FAQ answers that. Income of FY 2025–26 is filed as AY 2026–27, under the 1961 Act and the old ITR forms. Income of FY 2026–27 moves into the new framework. The portal runs both during the transition. None of that shifts the documentation question, and FY 2025–26 is where that question is answered first.

So FY 2025–26 is the bridge year. In law, Form 3CEB still applies to it. In practice, I would run this year to the Form 48 standard. If the FY 2025–26 study is assembled late, on partial data and after-the-event margin corrections, the same gaps appear in FY 2026–27, where the form asks for the granular version.

The smarter approach is to treat FY 2025–26 as a rehearsal with real consequences.

The real problem: books, TP policy and Form 48 must agree

For captive subsidiaries, this is where the issue becomes practical.

A captive IT or ITES unit may work on cost plus. But what is the cost base? Does it include stock compensation charged by the foreign parent? Then there are the software tools the AE provides, the travel costs borne overseas for Indian employees, and the training, secondment and outsourcing costs the AE incurs but India uses. Each one moves the margin.

Form 48 asks for these costs item by item: stock compensation or bonus paid by the assessee or the AE to employees; costs or depreciation of assets, software, tools, licences or databases provided by the AE; travel and training borne by AEs; secondment and outsourcing costs; and other AE-incurred expenses used in the business. On the revenue side it asks for forex fluctuation income, subsidies, grants, incentives, duty drawbacks, waivers, concessions and reimbursements.

This is operational transfer pricing in plain English. The form is indirectly asking: “Did your books capture the real economics of the transaction, and can you explain what was included or excluded in the ALP computation?”

A distributor faces a similar issue. Group pricing may target a certain return on sales, but local discounts, warranty provisions, marketing reimbursements, slow-moving stock and forex losses can quietly move the Indian entity outside the arm’s length range. If the TP study is prepared only after year-end, the team may discover the problem after the books are already closed.

A contract manufacturer has its own version of pain. Capacity utilisation, idle plant costs, raw material price variance, group-directed production changes and extraordinary costs can all affect margins. If these are not tracked during the year, the year-end TP analysis becomes a forensic exercise: less “transfer pricing study”, more “crime scene reconstruction”, except the only criminal is an unreconciled spreadsheet.

Why this affects Indian holding companies too

This issue is not limited to foreign MNCs with Indian captives. Indian groups with overseas subsidiaries also need to pay attention.

Outbound business models often involve management fees, cost allocations, loans, guarantees, royalties, software access, shared service charges and secondment arrangements. These are all transfer pricing-sensitive. Form 48’s transaction taxonomy includes financing, guarantees, services, intangibles, restructuring and cost contribution or cost allocation arrangements.

For Indian-headquartered groups, this means the parent company’s finance team cannot assume that TP is merely a foreign subsidiary compliance issue. If the Indian entity is receiving or paying intercompany charges, extending guarantees, lending funds, charging management fees or licensing intangibles, India-side reporting and documentation must be aligned.

The penalty angle: not new, but easier to trigger through bad process

The old law already had consequences. Departmental guidance notes three of them. Failure to keep or correctly report the documentation can attract a penalty under section 271AA of 2% of the value of each international transaction or specified domestic transaction. Failure to furnish Form 3CEB can attract a penalty of ₹1,00,000 under section 271BA. Failing to furnish information or documents under section 92D(3) can attract a penalty of 2% of the value of the relevant transaction for each failure.

The business risk, however, is wider than penalty. Poor TP documentation can lead to transfer pricing adjustments, interest, prolonged audits, dispute management costs, tax provisioning uncertainty, and uncomfortable board-level questions. The new Form 48 environment increases the chance that weak positions become visible earlier, because the form asks for the mechanics upfront.

What companies should start doing now

The first step is to stop treating the TP study as a post-filing comfort document. For FY 2025–26, companies should prepare the TP documentation in parallel with the Form 3CEB process, not months later. This gives the team an opportunity to identify data gaps, confirm transaction classifications, validate cost bases, test margins, and document true-up positions before the audit file goes cold.

The second step is to create a Form 48 readiness file, even for FY 2025–26. This does not mean filing Form 48 for a year when it is not applicable. It means mapping the current-year data to the future format: AE details, relationship codes, transaction categories, deemed international transactions, aggregation logic, method selection, comparable set, margin range, ALP computation, adjustment logic, further expense and revenue disclosures, and documentation confirmation.

The third step is to bring operational teams into the TP process. HR must know whether stock compensation and secondment costs matter. Treasury must track loans, guarantees and interest. Procurement must identify AE-provided tools or licences. Business teams must document restructurings and changes in functional profile. Finance must maintain clean segmentation. Tax cannot build a defensible Form 48 filing alone while sitting in a corner with a database subscription and strong coffee.

The larger shift: from compliance reporting to compliance readiness

The move from Form 3CEB to Form 48 points to a wider policy direction. The administration wants the reporting stage to carry the analysis, not only the figures, and it wants those figures comparable across taxpayers and readable by a machine. A position of “we believe this is arm’s length” will not carry. The chain has to run from the intercompany agreement to the books, from the books to the benchmarking, and from the benchmarking to the accountant’s certification.

That is a healthy development for serious taxpayers. It rewards discipline. It also exposes shortcuts.

For years, many businesses asked: “Can we prepare the TP study only if there is a notice?” Under the new reporting environment, the better question is: “Can we afford not to prepare it before filing?”

Conclusion: Form 48 is tomorrow's form, but today's problem

FY 2025–26 may still close under the old transfer pricing reporting framework. But the habits that will make or break FY 2026–27 compliance are being formed now.

Form 48 does more than replace a form. It changes how transfer pricing compliance feels from the inside. The study can no longer be a document produced after the fact, because the form now asks for its results at the time of filing. Contemporaneous documentation becomes a working habit rather than a year-end task. For companies that already maintain robust documentation, this is not a threat. It is validation. For those that relied on last-minute reporting and “we will prepare if selected” thinking, this is the warning light on the dashboard.

And as every finance professional knows, warning lights do not disappear because you turn up the music.

So the practical takeaway is this. Use FY 2025–26 to build the Form 48 discipline. Prepare the transfer pricing study on time, reconcile it with the books, test the margins before filing, and let the record describe the year as it was, not as it is reconstructed later. In transfer pricing, consistency is not style. It is defence.
