Treaty-based taxation of foreign salary and overriding title for compulsory social security contributions narrow taxable income

Foreign salary was taxable in India only to the extent it related to services actually rendered in India under the applicable treaty, so salary for periods worked outside India was excluded. Compulsory French social security contributions were treated as a diversion of income by overriding title because the levy operated as a prior charge at the earning stage, not as a post-receipt application of income, so only net salary was taxable.

Issues: (i) Whether salary received by foreign nationals for periods when they were outside India was taxable in India in respect of the entire salary or only to the extent of services rendered in India; (ii) whether compulsory social security contributions payable in France were deductible from salary income as a diversion of income by overriding title or were merely an application of income.

Issue (i): Whether salary received by foreign nationals for periods when they were outside India was taxable in India in respect of the entire salary or only to the extent of services rendered in India

Analysis: The taxing rights were governed by the relevant double taxation agreement, which contemplated taxation only in the State in which services were rendered. On the facts, the employees were in India only for part of the period and rendered services in India only for that period. Salary referable to services rendered outside India could not be brought to tax in India merely because the employment contract related principally to Indian work.

Conclusion: The issue was decided in favour of the assessee. Salary was taxable in India only for the period during which services were actually rendered in India.

Issue (ii): Whether compulsory social security contributions payable in France were deductible from salary income as a diversion of income by overriding title or were merely an application of income

Analysis: The French social security scheme imposed a compulsory affiliation and contribution on all French nationals, irrespective of place of work, and the contribution operated as a prior charge attached to the income at the earning stage. Applying the test of overriding title, the amount never became the assessee's free income to the extent of the compulsory contribution. The scheme was materially different from cases of mere appropriation or application of income after receipt.

Conclusion: The issue was decided in favour of the assessee. The social security contribution was deductible as a diversion of income by overriding title, and only net salary was liable to be taxed.

Final Conclusion: The appeals succeeded, and the salary income was to be assessed only on the basis of services rendered in India after deducting the compulsory French social security contribution.

Ratio Decidendi: Where foreign salary is taxable only for services rendered in India under the applicable treaty, and a foreign compulsory social security levy operates as a prior charge at the stage of earning, the taxed income is confined to the India-related salary after exclusion of that diverted amount.
