What Is Secondary Adjustment in Transfer Pricing?
A secondary adjustment is what happens after a transfer pricing adjustment is made but the cash never moves. If an Indian company's international transaction with a foreign associated enterprise is repriced to the arm's length price and the repricing increases the Indian company's taxable income by ₹1 crore or more, the law does not stop at taxing that extra income. It also asks: where is the money? If the "excess money" implied by the adjustment is still sitting with the foreign associated enterprise, it is treated as a deemed advance (an interest-bearing loan) from the Indian company to that enterprise until it is actually repatriated. The Indian company can instead close the matter by paying a one-time additional income-tax of 18% on the unrepatriated amount.
This is governed by transfer pricing law, specifically section 170 of the Income-tax Act, 2025 (section 92CE of the Income-tax Act, 1961). It matters because most transfer pricing adjustments are booked as accounting entries — nobody physically wires money back to India just because a tax return or an assessment order restates a price. Secondary adjustment closes that gap by forcing a choice: repatriate the cash, treat it as a loan and pay interest on it indefinitely, or pay 18% and be done with it.
Legal Basis
Section 170 of the Income-tax Act, 2025 (Section 92CE of the Income-tax Act, 1961)
Section 170 requires an assessee to make a secondary adjustment in every case where a primary adjustment of one crore rupees or more to the transfer price has occurred. "Primary adjustment" means a determination of the transfer price under the arm's length principle that increases the assessee's total income or reduces its loss. The threshold is applied to the amount of the primary adjustment itself, not to the size of the underlying transaction.
The Five Triggers for Secondary Adjustment
Section 170(1) applies wherever the ₹1 crore primary adjustment:
- has been made by the assessee on its own in its return of income;
- has been made by the Assessing Officer and accepted by the assessee;
- is determined by an Advance Pricing Agreement entered into under section 168 of the Income-tax Act, 2025 (section 92CC of the Income-tax Act, 1961);
- is made as per the safe harbour rules made under section 167 of the Income-tax Act, 2025 (section 92CB of the Income-tax Act, 1961); or
- arises from resolving an assessment through the mutual agreement procedure under an agreement entered into under section 159 of the Income-tax Act, 2025 (section 90 of the Income-tax Act, 1961) for avoidance of double taxation — that is, under a DTAA.
The scope is deliberately wide. It does not matter whether the transfer pricing dispute was resolved by the taxpayer conceding, an officer's order, a negotiated APA, a safe harbour election, or a cross-border MAP settlement — once the ₹1 crore threshold is crossed, secondary adjustment applies unless the taxpayer elects the 18% additional-tax route.
How the Deemed Advance Works
Section 170(9) defines "excess money" as the difference between the arm's length price determined in the primary adjustment and the price at which the international transaction was actually undertaken. If, as a result of the primary adjustment, the assessee's total income increases (or its loss reduces) and this excess money is not repatriated to India within the prescribed time, section 170(2) deems that excess money — or the part of it still outstanding — to be an advance made by the assessee to its associated enterprise.
Two features stand out. First, the excess money does not have to be repatriated from the same associated enterprise that was party to the original transaction — section 170(3) allows repatriation from any of the assessee's associated enterprises that is not resident in India. Second, "secondary adjustment" itself is defined narrowly in section 170(9)(d): it is an adjustment in the books of account of the assessee and its associated enterprise to align the actual allocation of profits with the arm's length transfer price, removing the imbalance between the assessee's cash position and its actual (post-adjustment) profit. The deemed-advance and interest consequences in section 170(2) and (4) are what give that book entry real financial cost.
This provision only applies to international transactions — the "excess money" definition in section 170(9)(b) is expressed in terms of an international transaction, so a primary adjustment to a specified domestic transaction between two Indian associated enterprises does not attract secondary adjustment.
The 90-Day Repatriation Window
The time limit for repatriation and the interest computation are prescribed under Rule 10CB. The rule sets a uniform 90-day window, but the start date depends on how the primary adjustment arose:
| Trigger | 90-day period runs from |
|---|---|
| Suo motu adjustment in the return | The due date for filing the return of income |
| Adjustment by the Assessing Officer or appellate authority, accepted by the assessee | The date of that order |
| Advance Pricing Agreement | The date of filing the return of income (where the APA was entered into on or before the return due date), or the end of the month in which the APA was entered into (where it was entered into after that date) |
| Safe harbour rules | The due date for filing the return of income |
| Mutual agreement procedure resolution | The date the Assessing Officer gives effect to the MAP resolution |
If the excess money is not repatriated within its applicable 90-day window, the deemed-advance treatment and interest under section 170(2) and (4) apply automatically — there is no separate notice requirement before interest starts running.
Interest on Unrepatriated Excess Money
Section 170(4) leaves the interest computation to be prescribed; Rule 10CB(2) fixes the benchmark:
- Rupee-denominated international transactions: the one-year marginal cost of fund-based lending rate (MCLR) of the State Bank of India as on 1 April of the relevant year, plus 325 basis points.
- Foreign-currency-denominated international transactions: the six-month London Interbank Offered Rate (LIBOR) as on 30 September of the relevant year, plus 300 basis points.
The foreign-currency limb is still expressed in the rule's own wording as the six-month London Interbank Offered Rate, even though that benchmark has been discontinued in the market; the rule has not been reworded to name a replacement reference rate.
Because the benchmark is reset annually and the interest accrues per annum for as long as the excess money stays abroad, the cost of leaving a large adjustment unrepatriated can run for years and grow substantially — which is precisely why section 170(5) offers a way out.
The One-Time 18% Additional Tax Option
Instead of repatriating the excess money or carrying it as an interest-bearing deemed advance indefinitely, section 170(5) lets the assessee elect to pay a one-time additional income-tax at the rate of 18% on the excess money (or the part of it) that has not been repatriated within the prescribed time. This election has several consequences that make it a genuine "close the file" option rather than just another layer of tax:
- Final payment (section 170(6)): the 18% tax is treated as the final payment of tax on that excess money — no credit for it can be claimed by the assessee or by anyone else.
- No further deduction (section 170(7)): no deduction under any other provision of the Act is allowed in respect of the amount on which this tax has been paid.
- Interest stops (section 170(8)): once the additional tax is paid, the assessee is not required to make the secondary adjustment under section 170(1), and interest under section 170(4) is computed only up to the date of payment — it does not continue to accrue afterward.
In effect, the 18% additional tax substitutes for both the deemed-loan interest and the obligation to actually bring the cash back to India.
Why This Matters for Foreign Companies
Foreign investors with Indian subsidiaries or branches often treat a transfer pricing dispute as resolved once income tax has been paid on the adjusted amount — through a return filing, an assessment order, an APA, or a MAP settlement. Section 170 is the reminder that resolving the tax liability is not the end of the story: the associated enterprise abroad is still holding cash that, on paper, belongs to the Indian entity's post-adjustment profit. Groups that route funds through India as part of a wider treasury or IP-licensing structure can find that a single transfer pricing adjustment — even one they accepted without dispute — creates an ongoing repatriation obligation, a running interest cost, or a one-time cash-tax cost of 18% on the whole adjustment amount. Because repatriation can come from any non-resident associated enterprise in the group, multinational groups have some flexibility in funding the repatriation, but the 90-day clock under Rule 10CB starts regardless of which entity in the group eventually sends the money.
Common Mistakes
- Assuming a settled transfer pricing dispute is fully closed. Accepting an Assessing Officer's adjustment, signing an APA, or reaching a MAP resolution only resolves the primary adjustment. Secondary adjustment is a separate, follow-on obligation once the ₹1 crore threshold is met.
- Missing the 90-day window because the trigger date is miscalculated. The clock runs from different events depending on how the adjustment arose — the return due date, the order date, the APA date, or the date the Assessing Officer gives effect to a MAP resolution — and using the wrong trigger date can mean interest has already been accruing without anyone noticing.
- Treating the 18% additional tax as automatic. It is an election under section 170(5), not a default outcome. Without actively paying it, the deemed-advance and interest consequences under section 170(2) and (4) continue to apply.
- Ignoring specified domestic transactions incorrectly. Secondary adjustment attaches to international transactions; conflating it with domestic transfer pricing exposure (which has its own consequences but not this deemed-loan mechanism) can lead to over- or under-stating exposure.
Practical Example
An Indian subsidiary accepts a transfer pricing adjustment of ₹5 crore proposed by the Assessing Officer, increasing its taxable income because it had been underpricing services billed to its foreign parent. If the ₹5 crore of excess money is not repatriated to India within 90 days of the date of that order, it is deemed an advance from the subsidiary to the parent, and interest starts accruing under Rule 10CB — at the SBI one-year MCLR as on 1 April plus 325 basis points if the transaction is rupee-denominated, or six-month LIBOR as on 30 September plus 300 basis points if it is foreign-currency-denominated — for as long as the amount remains outstanding. Alternatively, the subsidiary can elect under section 170(5) to pay a one-time additional tax of 18% on the ₹5 crore, i.e. ₹90 lakh. Once that payment is made, no further secondary adjustment, deemed advance, or ongoing interest applies, but the ₹90 lakh is a final tax cost with no credit and no deduction available against it.
Frequently Asked Questions
What is the difference between a primary adjustment and a secondary adjustment?
A primary adjustment restates the transfer price of an international transaction to the arm's length price, increasing taxable income or reducing a loss. A secondary adjustment is the follow-on step: aligning the books of account and, if the resulting excess money is not repatriated within the prescribed 90-day window, treating it as an interest-bearing deemed advance to the associated enterprise under section 170.
Does secondary adjustment apply if the adjustment came from an Advance Pricing Agreement or the mutual agreement procedure?
Yes. Section 170(1) explicitly lists an APA entered into under section 168 and a MAP resolution under a DTAA entered into under section 159 as two of the five triggers, alongside a self-made adjustment, an accepted Assessing Officer's order, and a safe harbour election. Reaching a negotiated resolution does not exempt the taxpayer from secondary adjustment.
What happens if the excess money is not repatriated within 90 days?
The unrepatriated excess money (or the part still outstanding) is deemed an advance from the assessee to its associated enterprise under section 170(2), and interest is computed on it under Rule 10CB — using the SBI one-year MCLR plus 325 basis points for rupee-denominated transactions, or six-month LIBOR plus 300 basis points for foreign-currency-denominated transactions — until it is repatriated or the 18% additional tax is paid.
Can a company avoid the deemed-advance treatment altogether?
Yes, in two ways: by actually repatriating the excess money to India within the applicable 90-day window, or by electing under section 170(5) to pay a one-time additional income-tax of 18% on the unrepatriated amount, which section 170(8) treats as removing the need to make the secondary adjustment or to keep computing interest.
Does secondary adjustment apply to domestic transactions between two Indian group companies?
No. Section 170(9)(b) defines "excess money" by reference to an international transaction, so the deemed-advance and interest mechanism under section 170 attaches only to cross-border transactions between an Indian assessee and its foreign associated enterprise, not to specified domestic transactions.
