Chapter X - Special Provisions Relating to Avoidance of Tax

Section 170

Section 170: secondary adjustment in certain cases

Section 170 deals with what happens after a transfer-pricing "primary adjustment" of ₹1 crore or more increases an assessee's income: if the resulting excess money sitting with the associated enterprise is not brought back to India in time, it is treated as a deemed advance (attracting notional interest), unless the assessee instead opts to pay an 18% additional tax on it.

Statutory text

Bare law

(1) An assessee shall make a secondary adjustment in every case where primary adjustment of one crore rupees or more to the transfer price— (a) has been made by the assessee on his own in his return of income; (b) made by the Assessing Officer has been accepted by him; (c) is determined by an advance pricing agreement entered into by him under section 168; (d) is made as per the safe harbour rules made under section 167; or (e) is arising as a result of resolution of an assessment by way of the mutual agreement procedure under an agreement entered into under section 159 for avoidance of double taxation.

(2) The excess money or part thereof available with its associated enterprise shall be deemed to be an advance made by the assessee to such associated enterprise if–– (a) as a result of primary adjustment to the transfer price, there is an increase in the total income or reduction in the loss, as the case may be, of the assessee; and (b) such excess money or part thereof is not repatriated to India within the time as may be prescribed.

(3) The excess money or part thereof referred to in sub-section (2) may be repatriated from any of the associated enterprises of the assessee which is not a resident in India.

(4) The interest on advance as referred to in sub-section (2) shall be computed in such manner as may be prescribed.

(5) Without prejudice to the provisions of sub-section (2), where the excess money or part thereof has not been repatriated within the prescribed time, the assessee may, at his option, pay additional income-tax at the rate of 18% on such excess money or part thereof, as the case may be.

(6) The tax on the excess money or part thereof so paid by the assessee under sub-section (5) shall be treated as the final payment of tax in respect of the excess money or part thereof not repatriated and no further credit thereof shall be claimed by the assessee or by any other person in respect of tax so paid.

(7) Deduction under any other provision of this Act shall not be allowed to the assessee in respect of the amount on which tax has been paid as per sub-section (5).

(8) In a case where the additional income-tax referred to in sub-section (5) is paid by the assessee, he shall not be required to make secondary adjustment under sub-section (1) and compute interest under sub-section (4) from the date of payment of such tax.

(9) For the purposes of this section,— (a) “arm’s length price” shall have the meaning assigned to it in section 173(a); (b) “excess money” means the difference between the arm’s length price determined in primary adjustment and the price at which the international transaction has actually been undertaken; (c) “primary adjustment” to a transfer price, means the determination of transfer price as per the arm’s length principle resulting in an increase in the total income or reduction in the loss, as the case may be, of the assessee; (d) “secondary adjustment” means an adjustment in the books of account of the assessee and its associated enterprise to reflect that the actual allocation of profits between the assessee and its associated enterprise are consistent with the transfer price determined as a result of primary adjustment, thereby removing the imbalance between cash account and actual profit of the assessee.

Introduction

Section 170 requires a secondary adjustment after a qualifying primary transfer-price adjustment of ₹1 crore or more. It addresses the excess money remaining with the associated enterprise and sets routes for repatriation, deemed advance and additional tax.

Key takeaways

1

Secondary adjustment

A qualifying primary transfer-pricing adjustment of at least ₹1 crore triggers the secondary-adjustment rule when it arises by one of the routes listed in subsection (1).

2

Cash consequence

The section addresses excess money not repatriated within the prescribed time by treating it as an advance and computing interest, subject to its exceptions and alternative tax option.

When a secondary adjustment is required

An assessee must make a secondary adjustment in every case where a primary adjustment of ₹1 crore or more to the transfer price:

  • has been made by the assessee on his own in his return of income;
  • made by the Assessing Officer has been accepted by him;
  • is determined by an advance pricing agreement entered into under Section 168;
  • is made as per the safe harbour rules made under Section 167; or
  • arises as a result of resolution of an assessment by way of the mutual agreement procedure under a double-taxation avoidance agreement entered into under Section 159.

Excess money treated as a deemed advance

If, as a result of the primary adjustment, there is an increase in the assessee's total income or reduction in loss, and the resulting "excess money" (or part of it) held by the associated enterprise is not repatriated to India within the prescribed time, that excess money (or the unrepatriated part) is deemed to be an advance made by the assessee to the associated enterprise.

This excess money may be repatriated from any of the assessee's associated enterprises that is not resident in India.

Interest on this deemed advance is computed in the manner prescribed.

Option to pay 18% additional income-tax instead

Instead of repatriating the excess money and computing notional interest, the assessee may, at his option, pay additional income-tax at the rate of 18% on the excess money (or part) not repatriated within the prescribed time.

Tax so paid is treated as the final payment of tax on that excess money - no further credit for it can be claimed by the assessee or any other person, and no deduction under any other provision of the Act is allowed in respect of the amount on which this tax has been paid.

Where this 18% additional tax is paid, the assessee is not required to separately make the secondary adjustment or compute notional interest from the date of payment of that tax.

Key definitions

For the purposes of this section:

  • "arm's length price" has the meaning assigned in Section 173(a).
  • "excess money" means the difference between the arm's length price determined in the primary adjustment and the price at which the international transaction was actually undertaken.
  • "primary adjustment" to a transfer price means determination of the transfer price as per the arm's length principle, resulting in an increase in total income or reduction in loss.
  • "secondary adjustment" means an adjustment in the books of account of the assessee and its associated enterprise to reflect that the actual allocation of profits between them is consistent with the transfer price determined by the primary adjustment - removing the imbalance between cash account and actual profit.

Step-by-step flow for applying Section 170

  1. 1

    Is there a primary adjustment of ₹1 crore or more?

    Made by the assessee in its return, made by the Assessing Officer and accepted, determined by an advance pricing agreement, made under safe harbour rules, or arising from a mutual agreement procedure resolution.

    • No: No secondary adjustment under Section 170(1).
    • Yes: Go to the next step.
  2. 2

    Make the secondary adjustment in the books

    Adjust the books of the assessee and its associated enterprise so that the allocation of profits matches the transfer price after the primary adjustment.

  3. 3

    Is the excess money repatriated to India within the prescribed time?

    It may come from any non-resident associated enterprise.

    • Yes: No deemed advance arises for the repatriated amount.
    • No: The unrepatriated amount is a deemed advance to the associated enterprise, and interest on it is computed in the prescribed manner.
  4. 4

    Does the assessee opt to pay additional income-tax of 18%?

    • Yes: 18% is paid on the unrepatriated excess money. It is the final payment of tax and no credit for it can be claimed; no deduction is allowed in respect of the amount on which it is paid; and no secondary adjustment or interest is needed from the date of payment.
    • No: Interest on the deemed advance continues to be computed in the prescribed manner.

Practical checklist

Do

  • Identify the primary adjustment amount and statutory route, including self-adjustment, accepted assessment, APA or safe harbour.
  • Track excess money, prescribed repatriation period and any deemed interest or additional-tax computation.

Avoid

  • Do not trigger a secondary adjustment below the ₹1 crore primary-adjustment threshold.
  • Do not assume a primary transfer-price adjustment automatically settles the movement of excess funds.

Illustrative example

Worked example: partial repatriation and the 18% option

Hypothetical facts (illustration only, not a real taxpayer): An Indian company accepts a primary adjustment made by the Assessing Officer that raises its total income by ₹1,50,00,000. This is the difference between the arm's length price and the price actually charged to its foreign associated enterprise. The associated enterprise sends ₹50,00,000 back to India within the prescribed time; the rest is not repatriated.

  1. Threshold

    ₹1,50,00,000 is at least ₹1 crore, and the adjustment was accepted by the assessee, so a secondary adjustment is required (Section 170(1)(b)).

  2. Excess money not repatriated

    ₹1,50,00,000 - ₹50,00,000 = ₹1,00,00,000 is deemed an advance to the associated enterprise, and interest is computed on it in the prescribed manner.

  3. Option under Section 170(5)

    If the company opts to pay additional income-tax: 18% of ₹1,00,00,000 = ₹18,00,000.

  4. Effect of paying

    The ₹18,00,000 is the final payment of tax on that amount, and no one can claim credit for it. No deduction under any other provision is allowed in respect of the ₹1,00,00,000 on which it was paid. From the date of payment, no further secondary adjustment or interest computation is needed.

Outcome

  • A primary adjustment below ₹1 crore (for example ₹80,00,000) would not trigger Section 170(1).
  • Interest for the period up to the date the 18% tax is paid is still computed in the prescribed manner; the option only stops it from that date.

Frequently asked questions

What triggers the secondary adjustment requirement under Section 170?

A transfer-pricing primary adjustment of ₹1 crore or more, whether made by the assessee himself, accepted from the Assessing Officer, fixed by an advance pricing agreement, arising under safe harbour rules, or resulting from a mutual agreement procedure under a tax treaty.

What happens if the excess money is not brought back to India?

It is deemed to be an advance made by the assessee to the associated enterprise, and notional interest on that deemed advance is computed in the prescribed manner.

Is there an alternative to computing notional interest every year?

Yes - the assessee may instead pay a one-time additional income-tax at 18% on the unrepatriated excess money, which is treated as final payment of tax on that amount, with no further credit or deduction available.
