Rule 12 of the Draft Income-tax Rules, 2026 prescribes the method for determining income attributable to assets located in India in cases of transfer outside India of shares or interests in a company or entity referred to in section 9(2). The income attributable to Indian assets is computed using a formula: (A × B) ÷ C. Here, A represents the total income from transfer computed as if the share or interest were located in India; B represents the fair market value (FMV) of assets located in India as on the specified date, derived substantially from such assets and computed under Rule 11; and C represents the FMV of all assets of the company or entity as on the specified date, also computed under Rule 11. If the transferor fails to provide required information for applying this formula, the Assessing Officer may determine the income in a manner deemed suitable. Further, the transferor must obtain and furnish, along with the return of income, a report in Form No. 4 certified by an accountant, confirming the correctness of the apportionment and computation of income attributable to Indian assets.
