1. The salary income and the foreign tax need not necessarily be converted using the same exchange rate. The applicable rules are different.
1. Conversion of Salary Income
You are correct that Rule 115 applies for conversion of salary income.
- Rule:Rule 115(c)
- Exchange Rate: Telegraphic Transfer Buying Rate (TTBR)
- Relevant Date: The last day of the month immediately preceding the month in which the salary is paid.
2. Conversion of Federal Tax Deducted (Foreign Tax Credit)
For the foreign federal tax deducted, the applicable provision is Rule 128, which governs Foreign Tax Credit (FTC), not Rule 115.
Under Rule 128(9), the foreign tax shall be converted into Indian Rupees at the TTBR on the last day of the month immediately preceding the month in which such foreign tax was paid or deducted, as the case may be.
Accordingly:
- If the US federal tax is withheld from salary each month, convert the tax deducted using the TTBR on the last day of the month immediately preceding the month in which the tax was deducted.
- If additional federal tax is paid later (e.g., on filing the US tax return), such payment should be converted using the TTBR on the last day of the month immediately preceding the month in which the payment was made.
Practical Illustration
Particulars | Applicable Rule | TTBR Date |
Salary received in April 2025 | Rule 115 | 31 March 2025 |
US federal tax withheld from April 2025 salary | Rule 128(9) | 31 March 2025 |
Additional US tax paid in October 2026 | Rule 128(9) | 30 September 2026 |
Practical Note
Where salary is paid and federal tax is simultaneously withheld each month (as is common in the US payroll system), the TTBR date under Rule 115 and Rule 128(9) will generally coincide. However, where there are subsequent tax payments or refunds upon filing the US return, the conversion date for those amounts will differ.
Therefore, for claiming FTC in India, the foreign tax should be converted in accordance with Rule 128(9), using the TTBR on the last day of the month immediately preceding the month in which the foreign tax was paid or deducted, and not necessarily using the exchange rate adopted for conversion of the salary income.
