Rule 83 of Income explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Rule 83 of the Income-tax Rules, 2026 gives ninety days to repatriate excess money after a primary transfer pricing adjustment under section 170(2), measured from one of six starting dates. Where it is not repatriated, imputed interest runs at the SBI one-year MCLR as on 1 April plus 325 basis points for rupee transactions, or the reference rate as on 30 September plus 300 basis points for foreign currency.
Why a secondary adjustment exists
A primary adjustment increases the taxpayer's income to an arm's length figure, but the cash stays where the original mispricing left it — with the associated enterprise. Section 170 treats that stranded cash as an advance to the associated enterprise, and rule 83 sets the deadline for bringing it back and the interest cost of not doing so.
The six starting dates — sub-rule (1)
For section 170(2)(b), the time limit for repatriation is on or before ninety days from the date in column C for the circumstance in column B.
| Sl. | Circumstance | Ninety days run from |
|---|---|---|
| 1 | Primary adjustments made suo motu by the assessee in its return of income | Due date of furnishing the return under section 263(1) |
| 2 | Primary adjustment as determined in the order of the Assessing Officer or the appellate authority, accepted by the assessee | Date of the order of the Assessing Officer or appellate authority |
| 3 | Primary adjustment determined by an advance pricing agreement under section 168 entered into on or before the return due date for the relevant tax year | Due date of furnishing the return under section 263(1) |
| 4 | Primary adjustment determined by an advance pricing agreement under section 168 entered into after the return due date for the relevant tax year | End of the month in which the advance pricing agreement was entered into |
| 5 | Option exercised by the assessee under the safe harbour rules in section 167 | Due date of furnishing the return under section 263(1) |
| 6 | Primary adjustment determined by a resolution under the mutual agreement procedure under a double taxation avoidance agreement entered into under section 159(1) or (2) | Date of the order giving effect under rule 121(10) to that resolution |
An advance pricing agreement signed on or before the return due date starts the clock at that due date. One signed after it starts the clock at the end of the month of signing. Since an advance pricing agreement covering earlier years is routinely signed years after those returns were filed, row 4 is the common case — and it gives a workable window, whereas applying row 3 to a late-signed agreement would make the deadline already past on the day of signature.
Row 5 is easily missed. Electing safe harbour under section 167 does engage the secondary adjustment machinery, with the clock running from the return due date. Safe harbour removes the transfer pricing dispute; it does not remove the repatriation obligation.
The interest charge — sub-rules (2) and (3)
The imputed per annum interest income on excess money not repatriated within the sub-rule (1) time limit is computed:
| Denomination | Rate | Rate fixing date |
|---|---|---|
| Indian rupee | One-year marginal cost of funds lending rate of the State Bank of India plus 325 basis points | As on 1 April of the relevant tax year |
| Foreign currency | Reference rate of the relevant foreign currency, as defined in rule 89(3), plus 300 basis points | As on 30 September of the relevant tax year |
Under sub-rule (3), the interest is chargeable on the excess money or part of it that is not repatriated, from the date mentioned in column C of the sub-rule (1) Table.
Sub-rule (1) gives ninety days to repatriate. Sub-rule (3) then charges interest from the column C date itself where repatriation does not happen in time. Missing the deadline by a day therefore does not cost a day's interest — it costs interest for the whole period from the column C date onwards. The ninety days is a grace period that is lost entirely if it is not used.
Note also that the two rates are fixed on different dates — 1 April for rupee transactions and 30 September for foreign currency — and that the foreign currency reference rate is the one defined in rule 89(3), the safe harbour rule. That definition carries a currency-by-currency list with its own uplifts, so the applicable rate for a US dollar transaction is not the bare benchmark.
Currency conversion — sub-rule (4)
The exchange rate for converting the value of international transactions denominated in foreign currency into Indian rupees is the telegraphic transfer buying rate of that currency on the last day of the tax year in which the transaction was undertaken, with "telegraphic transfer buying rate" carrying the meaning in rule 207.
The conversion date is the last day of the transaction's tax year — not the transaction date, and not the date of the adjustment or the repatriation.
Rule 10CB and rule 83 compared
| Point | Rule 10CB (1962) | Rule 83 (2026) |
|---|---|---|
| Parent provision | Section 92CE | Section 170 |
| Repatriation window | Ninety days | Ninety days |
| Number of starting dates | Six circumstances | Six circumstances |
| Rupee rate | SBI one-year MCLR plus 325 bps | SBI one-year MCLR plus 325 bps, as on 1 April |
| Foreign currency rate | Six-month benchmark plus 300 bps | Reference rate per rule 89(3) plus 300 bps, as on 30 September |
| Mutual agreement procedure limb | Order giving effect | Order giving effect under rule 121(10) |
| Conversion rate | TT buying rate | TT buying rate on the last day of the transaction's tax year |
Worked example
An Indian company makes a suo motu primary adjustment of Rs 6 crore in its return for tax year 2026-27, on a transaction denominated in Indian rupees.
- Row 1 applies, so the ninety days run from the section 263(1) due date for that return.
- If the Rs 6 crore is repatriated within those ninety days, no interest arises.
- If it is not, interest runs at the SBI one-year MCLR as on 1 April 2026 plus 325 basis points, and it runs from the return due date — not from the ninety-first day.
- Had the same adjustment arisen from an advance pricing agreement signed in, say, November 2028 for tax year 2026-27, row 4 would apply and the ninety days would run from 30 November 2028.
Compliance checklist
- Identify the correct row of the sub-rule (1) Table — the starting date differs by six weeks to several years between them.
- For an advance pricing agreement, check whether it was signed before or after the return due date.
- Remember that a safe harbour election under section 167 is row 5 and does engage the rule.
- Treat the ninety days as a use-it-or-lose-it grace period; interest backdates to the column C date.
- Fix the rupee rate at the 1 April SBI one-year MCLR and the foreign currency rate at the 30 September reference rate under rule 89(3).
- Convert at the TT buying rate on the last day of the transaction's tax year.
- Cite rule 83 and section 170, not rule 10CB and section 92CE.
Common mistakes
- Charging interest only from the ninety-first day.
- Applying row 3 to an advance pricing agreement signed after the return due date.
- Assuming safe harbour removes the repatriation obligation.
- Using a single rate-fixing date for both rupee and foreign currency transactions.
- Using the bare foreign benchmark instead of the rule 89(3) reference rate with its uplift.
- Converting at the transaction date rather than the last day of the transaction's tax year.
