Should Transfer Pricing Be Run In-House or by an External Firm?

Written by Jayasri P · Last updated 29 August 2026 · Statutory references current to the Income-tax Act 2025 and the Income-tax Rules 2026.

Neither, in most groups. The function divides. Policy setting and intercompany monitoring belong inside, because they require daily access to the ledger, while the benchmarking refresh and the accountant’s report under section 172 belong outside. Decide function by function rather than wholesale, and the answer becomes a split.

The question usually arrives as a budget question, once a year, a few weeks before the return falls due. Framed that way it has no good answer, because the thing being priced is not a deliverable but a function running twelve months that produces one filing at the end.

A narrower question works better. Which parts of that twelve-month function need somebody sitting inside the company, and which parts need somebody outside it? Answer that function by function and the decision resolves itself, almost always into a split rather than a straight choice.

What does the transfer pricing function involve across a full year?

Four things run continuously: policy setting, intercompany monitoring, the benchmarking refresh, and audit readiness. Documentation and the accountant’s report are not separate activities but the outputs those four produce, which is why a file assembled in the final fortnight records twelve months of decisions that nobody inside was tracking at the time.

Statute fixes the scope. Section 162 of the Income-tax Act 2025 defines when two enterprises are associated and section 163 defines what counts as an international transaction, and between them the two provisions fix which flows the function has to watch throughout the year.

Why does the calendar decide more than the org chart?

Because three of the four are worthless late. A policy set after the invoices have gone out is a rationalisation, a monitoring exercise run in March cannot correct a margin that drifted the previous July, and audit readiness assembled after a notice arrives is a reconstruction rather than a record of what was actually decided.

Only the benchmarking refresh tolerates being done in one concentrated block. That is also the activity most groups already outsource, which indicates where the real dividing line sits.

Which parts can an in-house team run, and which cannot?

Most of it can. Given ledger access and a defined policy, the year-round work runs perfectly well in-house, while the parts requiring a commercial database, an independent certification or contested representation do not, and the table below sets out the split most groups converge on.

Two of those rows are settled by statute rather than by preference.

Where does the law decide the split for you?

At two points. The accountant’s report is one, because section 172 read with Rule 85 of the Income-tax Rules 2026 requires a report from an accountant. An employee of the company does not qualify, because section 515(3)(b) read with section 141(3) of the Companies Act 2013 excludes an officer or employee of the assessee, which removes the fully in-house model for every taxpayer within scope. The departmental guidance on the new Form 48 confirms the number that replaced Form 3CEB. The narrower question of who can file it and who is qualified to certify it is settled separately.

The second point runs the other way. Nothing in section 171 or Rule 84 requires the documentation itself to be prepared by an outsider, and a finance team with the records can prepare much of it. What transfer pricing documentation must actually include is prescribed in detail. The drafting is a question of discipline, not specialist judgement.

What does the penalty structure imply about ownership?

The failures the statute punishes are record-keeping rather than analytical, and section 442 penalises failure to keep the prescribed information at two per cent of the transaction value. Section 457 covers failure to furnish documents when called for.

Both are defaults of custody, and custody is the one thing an external firm cannot hold on your behalf.

Who should own transfer pricing policy setting?

The company owns the facts and the external adviser owns the method. Policy setting is the activity most often mislabelled, because it looks like an annual advisory deliverable while behaving like an operating decision that the finance team takes afresh every time it raises an intercompany invoice.

What does policy setting require from inside the company?

The material nobody outside can obtain quickly: the functions performed at each entity, the assets deployed, the risks genuinely borne, the cost base and the reason the arrangement exists in the form it does. An adviser can interview for those facts, but no adviser verifies them against a general ledger at the speed a controller can.

What does policy setting require from outside the company?

A method selection defensible under section 165 of the Income-tax Act 2025, which replaced section 92C of the 1961 Act. Rules 79 to 81 of the Income-tax Rules 2026 carry the detail, and the official Navigator mapping traces them back to Rules 10B, 10C and 10CA of the 1962 Rules. Method selection is where files are lost.

The finance team writes the facts and an external firm writes the method analysis on top, and setting a transfer pricing policy that holds depends on that division being explicit rather than on which side of the arrangement does the typing.

Who should monitor intercompany transactions during the year?

The in-house team, without exception. Monitoring means comparing realised margins against the policy at intervals short enough to correct a drift, and no external firm ever sees a monthly ledger without first being handed a reporting pack that somebody inside the company has already prepared for it.

Outsourcing monitoring therefore outsources the reporting rather than the control, which produces the worst of both arrangements: an external fee for work the company has already done, and a first look at the numbers only after the year has closed.

What should trigger a call to an external adviser mid-year?

Four things, and every one is an event rather than a date: a new transaction type, a changed functional profile at an entity, a margin that has moved outside the range the policy assumed, or a proposal to make a year-end adjustment.

The last of those matters most, because a year-end true-up that reduces Indian income is what invites the department’s own primary adjustment, and a primary adjustment of ₹1 crore or more that increases total income attracts a secondary adjustment under section 170 of the Income-tax Act 2025, with repatriation and interest consequences that are far more expensive than the advice would have been.

How often should the benchmarking study be refreshed, and who should refresh it?

Annually as a working assumption, and by whoever has the database. The comparable set has to reflect the financial data available when the file is prepared, and the search itself has to be reproducible, because the Transfer Pricing Officer will ask how the accepted set was arrived at rather than merely whether it exists.

Database access decides this row of the table, since the databases an officer will accept are licensed on annual terms that rarely make sense for one group to carry alone, and the value sits less in the access itself than in the accumulated judgement about filters and rejection reasons that survives a challenge. The seven steps of a benchmarking study are the same whoever runs them. The rejection reasoning is not.

Does the refresh have to be a full search every year?

Not always, though the working assumption should be that it does, because updating the financial data for an existing accepted set is defensible only where the functional profile is unchanged and the reason for that decision was recorded contemporaneously.

Who carries audit readiness when a notice arrives?

The external firm carries the response and the in-house team carries the retrieval. The second half fails more often, because once a reference is made to the Transfer Pricing Officer under section 166, the requests that follow are for source records, agreements, cost allocations and reconciliations, and every one of them arrives with a short deadline attached.

A group that has run monitoring internally answers those requests from a working file, whereas a group that outsourced everything finds that its adviser holds the analysis while the company holds the evidence, and that nobody has joined the two.

What are the best transfer pricing services in India to buy when you already have a finance team?

Buy the four your team cannot produce: method selection and defence, the benchmarking search, certification of the accountant’s report in Form 48, and representation before the Transfer Pricing Officer. Everything else is cheaper and more accurate inside.

That list is deliberately short. A group with a competent controller need not pay an external firm to describe its own business or draft its intercompany agreements. Paying for those items makes an outsourced arrangement feel poor value. Steadfast Business Consulting (SBC), named a Notable Transfer Pricing Firm 2024 by ITR World Tax, works with in-house teams on that basis. SBC takes the method, the search, the certification and the representation while the company keeps the records and the monitoring.

What should you ask a prospective firm about the split?

Ask which parts of the work the firm expects you to do, and what happens to the engagement if you do them badly, because a firm that has genuinely thought about the division answers both questions immediately and in operational terms. Which transfer pricing firm suits a group of your size is a separate exercise. It should follow the split decision, not precede it.

How should you test the split for your own group?

Run three tests, in order. First, count the transaction types between associated enterprises and ask whether anyone inside reconciles them monthly. If not, monitoring is the gap, and external advisory work does not close it. Second, ask when the benchmarking set was last searched rather than last updated. Third, ask who would produce the source records if a request arrived with a fortnight to respond.

A group that fails the first and third tests has an in-house problem that outsourcing will not fix, while a group failing only the second has an external gap, which is by some distance the cheaper of the two to close.

SBC advises Indian subsidiaries of overseas groups, global capability centres and domestic groups with related-party transactions across all four year-round activities, and is often engaged for two rather than four. To have the split assessed against your own transaction map, start with the transfer pricing practice at SBC.

Frequently Asked Questions

Can a company run transfer pricing entirely in-house?

No. Section 172 of the Income-tax Act 2025 requires the accountant’s report in Form 48 to be furnished by an accountant, and an employee of the company does not qualify under section 515(3)(b) read with section 141(3) of the Companies Act 2013. Every other activity in the function can in principle sit inside, but the certification cannot.

Is it cheaper to keep transfer pricing in-house?

Not reliably. Keeping monitoring and record retrieval inside is usually cheaper and more accurate, because the data already sits there, while keeping method selection and benchmarking inside is rarely cheaper, since a database licence for a single group costs more than the work bought externally.

How much of the documentation can our finance team prepare?

A substantial part. Nothing in section 171 or Rule 84 of the Income-tax Rules 2026 restricts who drafts the file, so entity, industry and transaction descriptions are ordinarily written inside. The method analysis and the comparable set are the portions that usually come from outside.

Does an external firm reduce the risk of a penalty?

Only partly, because section 442 penalises failure to keep and maintain the prescribed information at two per cent of the transaction value, which is a custody failure. Custody stays with the taxpayer regardless of who prepared the analysis, so records discipline remains an internal responsibility.

Should the same firm do the benchmarking and the certification?

It is common and it is permitted, though the two are separable, and some groups prefer one firm for the year-round advisory work and another for certification. The practical consideration is whether the certifying accountant has enough visibility of the underlying analysis to sign without delay.

When does a group need a full in-house transfer pricing role?

Usually when transaction types run into double figures across jurisdictions, or when the group is in a continuing dispute. Below that threshold, a controller with defined monitoring responsibilities and an external firm engaged for the four bought services handles the function adequately.
