Safe Harbour, APA, Secondary Adjustment and Thin Capitalisation (CA Final DT)
Updated 5 October 2026 · Fact-checked
Safe harbour, APA, secondary adjustment and thin capitalisation are transfer pricing tools. Safe harbour and APA give certainty on the arm's length price. Secondary adjustment forces repatriation of excess money after a price adjustment. Under thin capitalisation, interest paid or payable to a non-resident associated enterprise above 30% of EBITDA is disallowed, where that interest exceeds ₹1 crore.
Understand Safe Harbour, APA, Secondary Adjustment and Thin Capitalisation
Transfer pricing starts with one idea: transactions between associated enterprises must be priced as if the parties were independent. That price is the arm's length price (ALP). Disputes about ALP are long and costly. So the law gives you ways to get certainty, and ways to stop value leaking out of India.
Safe harbour is the simplest certainty tool. The rules set out circumstances, such as a minimum margin for a class of transaction, in which the tax authority accepts the price you declared. If you are an eligible assessee with an eligible transaction and you opt in as the rules require, the authority does not go behind your price. The margins and thresholds are in the prescribed rules, so check the current table before you quote any number.
An Advance Pricing Agreement (APA) is an agreement between the CBDT and a taxpayer. It fixes the ALP, or the method of finding it, for specified future international transactions. A unilateral APA is between the taxpayer and the CBDT only. A bilateral APA also involves the competent authority of the treaty partner country and works through the mutual agreement procedure. A multilateral APA involves more than two countries. The agreement covers a fixed number of future years, and a rollback can extend it to earlier years. It binds both the taxpayer and the department for the covered transactions, unless the law changes or the agreed critical assumptions fail.
A secondary adjustment follows a primary adjustment. When the transfer price is changed, the taxpayer's income goes up, but the extra money stays with the foreign associated enterprise. The law says this excess money must be brought back to India within the prescribed time. The proviso to section 92CE excludes small primary adjustments (₹1 crore or less) and older years. Its conditions have been amended over time, so check the current text before you rely on the threshold. If the money is not brought back, it is treated as a deemed advance to the associated enterprise, and interest on it is added to your income. Alternatively, you can pay additional income-tax on the excess at a flat 18%, plus surcharge and cess at the rates applicable, and then no secondary adjustment is made. The 18% is fixed, but the surcharge and cess are not, so check the applicable rates. As an illustration only, a 25% surcharge and 4% cess would give an effective rate of 23.4%.
Thin capitalisation (limitation on interest deduction) stops a group from loading an Indian entity with debt from a foreign associated enterprise to shift profit out as deductible interest. The 30% of EBITDA cap is applied to the interest paid or payable to the non-resident associated enterprise, including on a loan that the associated enterprise guarantees. Interest to third parties is not caught by this rule. Where that interest exceeds ₹1 crore, the part above 30% of EBITDA is disallowed. The deductible amount is the cap, or the associated enterprise interest if that is lower. The disallowed interest can be carried forward for up to 8 tax years immediately following the year of disallowance. It is deductible in those years only to the extent of the 30% EBITDA headroom, which is the cap less the interest actually claimed in that year. Penalties apply for weak documentation, non-reporting and under-reporting of income.
Key rules to remember
- Interest limitation (thin capitalisation)
- Excess interest = interest paid or payable to the associated enterprise − 30% of EBITDA (nil if negative). Deductible associated enterprise interest = associated enterprise interest − excess interest
- Applies where interest to the non-resident associated enterprise (including on a loan guaranteed by it) exceeds ₹1 crore. The excess is not deductible. The cap is 30% of EBITDA, or the associated enterprise interest if that is lower. Interest paid to other lenders is not disallowed under this rule.
- EBITDA for the cap
- EBITDA = Profit before interest, tax, depreciation and amortisation
- Use the figure from the profit and loss account, adjusted as the Act requires. Do not use total income.
- Carry forward of disallowed interest
- Disallowed interest can be carried forward for up to 8 tax years immediately following the year of disallowance, and deducted within the 30% EBITDA headroom of those years
- Headroom = 30% of EBITDA of that year less the interest actually claimed in that year. Set off the carried-forward interest only up to that headroom.
- Secondary adjustment trigger
- Primary adjustment above ₹1 crore, subject to the other conditions in the proviso to section 92CE → excess money to be repatriated within the prescribed time (90 days)
- Primary adjustment may arise from: a suo motu adjustment by the taxpayer in the return; an adjustment made by the Assessing Officer and accepted by the taxpayer; an adjustment determined by an APA; an adjustment made under the safe harbour rules; or a resolution under the mutual agreement procedure. The proviso excludes primary adjustments of ₹1 crore or less and older years. Its conditions have been amended over time, and they differ for older years. Check the current text before you rely on the threshold.
- Imputed interest on deemed advance
- Interest = Excess money not repatriated × prescribed rate × period outstanding
- The rate is fixed in the prescribed rules and differs for rupee and foreign currency transactions. The interest is treated as the taxpayer's income.
- Option to pay additional tax
- Additional income-tax = 18% × excess money, plus surcharge and cess at the applicable rates. Illustration only: with a 25% surcharge and 4% cess, effective rate = 18% × 1.25 × 1.04 = 23.4%
- The 18% is a flat rate under section 92CE. The surcharge and cess depend on the rates applicable, so the 23.4% holds only under the stated illustrative assumptions of a 25% surcharge and 4% cess. Once the tax is paid, no secondary adjustment is made and no further credit or deduction is allowed for it. The manner of payment is set out in the prescribed rules.
- APA types and period
- Unilateral = CBDT + taxpayer; Bilateral = CBDT + taxpayer + one treaty partner's competent authority; Multilateral = more than two countries. Future period up to 5 tax years; rollback up to 4 earlier years
- Rollback applies to the same international transaction and needs the conditions in the prescribed rules to be met. The agreement is void if obtained by fraud or misrepresentation.
- Key transfer pricing penalties
- 2% of transaction value for failure to maintain documents, report a transaction or furnish documents (each default attracts the penalty separately); ₹1 lakh for failure to furnish the accountant's report. Separately, the general penalties for under-reporting (50% of tax on under-reported income) and misreporting (200%) apply to the income that a transfer pricing adjustment brings in
- The 50% and 200% rates are the general under-reporting and misreporting penalties, not special transfer pricing penalties. Quote the rate along with the default. Check the Act's text for the exact conditions, including the reasonable cause defence.
How to solve Safe Harbour, APA, Secondary Adjustment and Thin Capitalisation questions
Use this method for any question on this topic. It works for descriptive answers and for case-scenario MCQs.
- 1Identify which tool the facts point to: safe harbour, APA, secondary adjustment, interest limitation or penalty.
- 2Confirm the base condition. Is there an international transaction with an associated enterprise? Is the lender a non-resident associated enterprise? Was there a primary adjustment?
- 3Test the threshold and eligibility: ₹1 crore for interest and for secondary adjustment, transaction type for safe harbour, and notified jurisdiction exclusions.
- 4State the rule in plain words and apply it to the facts. For an APA, name the type and the parties. For a secondary adjustment, give the time limit and the consequence.
- 5Compute step by step. For interest, take 30% of EBITDA first, then interest paid or payable to the associated enterprise less that figure. That is the disallowed excess, and it is nil if negative. For secondary adjustment, take the excess money, the rate and the period.
- 6Show the effect: disallowed amount, carry forward, deemed advance, imputed interest or penalty.
- 7Close with a one-line conclusion and mention any option, such as paying additional tax in place of repatriation.
Quickest way: Three-check shortcut
When to use it: Use it for MCQs and for short-note questions where you have about five minutes.
- Check 1, who is the party? A non-resident associated enterprise lender means thin capitalisation. A treaty partner means a bilateral APA. An accepted adjustment means a secondary adjustment.
- Check 2, is the ₹1 crore threshold crossed? If not, the interest cap or secondary adjustment usually does not apply.
- Check 3, compute: excess interest = interest to the associated enterprise − 30% of EBITDA. That excess is disallowed.
- Write the consequence in one line, such as disallowed interest carried forward for up to 8 tax years within the EBITDA headroom.
Common mistakes in Safe Harbour, APA, Secondary Adjustment and Thin Capitalisation
Applying the 30% cap to total interest instead of only to the interest paid to the associated enterprise.
Students remember '30% of EBITDA' and apply it to every interest cost.
Fix: Take only the interest paid or payable to the non-resident associated enterprise. Deduct 30% of EBITDA. The balance is the disallowed excess, provided the associated enterprise interest exceeds ₹1 crore. Interest paid to other lenders is not disallowed under this rule.
Treating a bilateral APA as one signed only by the taxpayer and the CBDT.
The word 'bilateral' is read as two parties in total.
Fix: Bilateral means a treaty partner's competent authority is also involved, so there are three parties. Unilateral has two parties. Multilateral involves more than two countries.
Ignoring the time limit and threshold for secondary adjustment.
Students treat every primary adjustment as triggering interest.
Fix: Check the ₹1 crore limit and the year conditions in the proviso to section 92CE. These have been amended, so confirm the current text. Then check whether repatriation was made within the prescribed 90 days. Only then impute interest on the deemed advance.
Saying that a safe harbour or APA applies to all transactions of the assessee.
Students overlook the 'eligible' conditions.
Fix: Safe harbour covers only eligible assessees and eligible transactions, and not transactions with associated enterprises in notified jurisdictions. An APA covers only the transactions and years named in it.
Treating disallowed interest as lost forever.
The carry forward rule is forgotten.
Fix: Disallowed excess interest can be carried forward for up to 8 tax years immediately following the year of disallowance. It is allowed in later years only within the 30% EBITDA headroom, which is the cap less the interest actually claimed in that year.
Quoting penalties without the default they relate to, or calling 50% and 200% transfer pricing penalties.
Penalty rates are memorised as a list.
Fix: Learn each as default and rate together, for example failure to maintain documents with 2% of transaction value. The 50% (under-reporting) and 200% (misreporting) rates are general penalties that reach a transfer pricing adjustment only through the income it adds.
Worked examples
Example 1
Case: Zenith Components Pvt Ltd, an Indian company, has EBITDA of ₹10,00,00,000 for the tax year. It pays total interest of ₹6,00,00,000, of which ₹4,50,00,000 is paid to its non-resident parent, an associated enterprise. It is not a bank or an insurer. Determine the interest allowed and the treatment of the balance.
Show the solution
- Interest to the associated enterprise is ₹4.5 crore, which exceeds ₹1 crore. So the limitation applies.
- 30% of EBITDA = 30% × ₹10,00,00,000 = ₹3,00,00,000.
- Interest to the associated enterprise = ₹4,50,00,000.
- Excess interest = ₹4,50,00,000 − ₹3,00,00,000 = ₹1,50,00,000. This is disallowed.
- Interest to the associated enterprise that is allowed = ₹4,50,00,000 − ₹1,50,00,000 = ₹3,00,00,000.
- Interest paid to other lenders = ₹6,00,00,000 − ₹4,50,00,000 = ₹1,50,00,000. It is not affected by this rule.
- Total interest allowed = ₹6,00,00,000 − ₹1,50,00,000 = ₹4,50,00,000.
- The ₹1,50,00,000 disallowed can be carried forward for up to 8 tax years immediately following this year. It is allowed in those years only within the 30% EBITDA headroom, which is the cap less the interest actually claimed in that year.
Answer: Interest of ₹4,50,00,000 is allowed. Interest of ₹1,50,00,000 is disallowed and can be carried forward for up to 8 tax years, within the 30% EBITDA headroom of those years.
Example 2
Case: The assessing authority made a primary adjustment of ₹2,40,00,000 to the price of services Arvind Tech India Ltd provided to its foreign associated enterprise, relating to AY 2016-17 or later, and the company accepted it. The excess money was not repatriated within the prescribed 90 days. Assume, for illustration only, that the prescribed interest rate is 11% per annum and that the amount stayed outstanding for 6 months after the due date. Assume also, for illustration only, a 25% surcharge and 4% cess on the additional tax; the actual surcharge and cess depend on the applicable rates. Explain the secondary adjustment and compute the imputed interest and the alternative tax.
Show the solution
- The primary adjustment is ₹2.4 crore, which exceeds ₹1 crore. It relates to AY 2016-17 or later and was accepted by the taxpayer. So secondary adjustment applies, on the conditions in the proviso to section 92CE.
- The excess money should have been brought to India within 90 days. It was not, so it is treated as a deemed advance to the associated enterprise.
- Imputed interest = ₹2,40,00,000 × 11% × 6/12 = ₹13,20,000. The 11% rate is only an illustrative assumption; use the rate in the prescribed rules. This interest is added to the company's income.
- Alternative: the company may pay additional income-tax at the flat rate of 18% on the excess money, plus surcharge and cess at the applicable rates, as per the prescribed rules. 18% × ₹2,40,00,000 = ₹43,20,000.
- Using the illustrative 25% surcharge: 25% × ₹43,20,000 = ₹10,80,000. Tax plus surcharge = ₹54,00,000.
- Using the illustrative 4% cess: 4% × ₹54,00,000 = ₹2,16,000. Total additional tax = ₹54,00,000 + ₹2,16,000 = ₹56,16,000 (effective rate 23.4% of ₹2,40,00,000, under these assumptions only).
- If the additional tax is paid, no secondary adjustment is made and no interest is imputed. No credit or deduction is allowed for this additional tax.
Answer: Without repatriation, ₹13,20,000 of imputed interest (at the assumed 11% rate) is added to income on the deemed advance. Alternatively, the company can pay additional tax at a flat 18% plus surcharge and cess. Under the illustrative assumptions of a 25% surcharge and 4% cess, this is ₹56,16,000, and no secondary adjustment is made.
Exam tips
- Write the type of APA first, then the parties, then the period. Examiners give marks for the three-party versus two-party distinction.
- For the interest limitation, show the 30% EBITDA working in a separate line. Marks are given for each step even if the final figure is wrong.
- Use the phrases 'primary adjustment', 'deemed advance' and 'repatriation' in secondary adjustment answers.
- Check the case facts for banks, insurers, loans guaranteed by the associated enterprise and the ₹1 crore threshold. These are the usual traps in the MCQ.
- Use the Income-tax Act, 2025 term 'tax year' in your answers. Do not refer to the 1961 Act or to 'assessment year' except where a rule is dated by its original year, such as AY 2016-17.

Safe Harbour, APA, Secondary Adjustment and Thin Capitalisation: frequently asked questions
What is the difference between unilateral, bilateral and multilateral APA?
A unilateral APA is between the taxpayer and the CBDT only. A bilateral APA also involves the competent authority of one treaty partner and uses the mutual agreement procedure. A multilateral APA involves more than two countries, so it removes double taxation across all of them.
Does safe harbour mean no transfer pricing scrutiny at all?
For an eligible assessee and an eligible transaction that meets the prescribed margin, the tax authority accepts the declared price. It does not carry out a comparability analysis. But the rules apply only to the covered transactions, and they exclude dealings with associated enterprises in notified jurisdictions.
What happens if I do not repatriate the excess money after a primary adjustment?
If the primary adjustment exceeds ₹1 crore and the excess money is not brought to India within the prescribed time, it is treated as an advance to the associated enterprise. Interest at the prescribed rate is then added to your income. You can instead pay additional income-tax at 18% (plus surcharge and cess) on the excess money.
Which interest is covered by the thin capitalisation rule?
It covers interest paid by an Indian company or the permanent establishment of a foreign company to a non-resident associated enterprise, including where the associated enterprise guarantees a loan from a third party. It applies where the interest exceeds ₹1 crore. Banks and insurance businesses are outside the rule.
