Supreme Court on Employee Secondment: When Overseas Deputation Can Become a Taxable Service
The Supreme Court’s ruling in CC, CE & ST Bangalore v. Northern Operating Systems Pvt. Ltd. remains one of the most important judicial decisions on the tax treatment of employee secondment arrangements in India. The dispute centered on whether reimbursement of salary cost by an Indian entity to an overseas group company, in relation to seconded employees, could be treated as consideration for a taxable service.
The Court ultimately held that, on the facts of the case, the Indian entity was the recipient of a taxable service from the overseas group company. The arrangement was viewed as a form of manpower supply, not a pure employer-employee relationship. This ruling has had a lasting impact on the tax analysis of cross-border secondment structures, particularly in cases involving overseas group entities deputing personnel to Indian affiliates.
Background: Why Secondment Arrangements Became a Tax Dispute
Cross-border secondment is common in multinational groups where technical, managerial, or leadership personnel are deployed to India for a defined period. In many such cases, the secondees work under the day-to-day direction of the Indian entity while remaining on the payroll of the overseas employer and retaining overseas employment rights.
The core tax question in such arrangements is whether the seconded individual becomes an employee of the Indian entity for tax purposes or whether the overseas group entity is effectively supplying manpower or services to the Indian company. That distinction becomes critical in determining whether indirect tax exposure arises under the reverse charge framework.
Key Facts in the Northern Operating Systems Case
In the Northern Operating Systems case, the Indian entity had entered into arrangements with overseas group companies for back-office and operational support. Managerial and technical personnel were seconded to India for a limited period. Although the Indian entity exercised operational control over the secondees and undertook certain local payroll and compliance obligations, the secondees continued on the payroll of the overseas entity and were repatriated to that overseas employer after the secondment period.
The tax authorities treated the reimbursement of salary and related costs to the overseas entity as consideration for manpower recruitment or supply service. The assessee argued that an employer-employee relationship existed with the Indian entity and that the arrangement should therefore fall outside the scope of taxable service.
What the Supreme Court Held
The Supreme Court rejected any single-factor test for determining the employer-employee relationship and instead adopted a substance-over-form approach. After reviewing the master service agreements, secondment agreements, and related documentation, the Court concluded that the “real” employer continued to be the overseas group entity in the fact pattern before it.
The Court placed weight on factors such as
- continued payroll and employment lien with the overseas entity;
- the temporary nature of secondment;
- the repatriation of employees to the overseas entity after the deputation period;
- the specialized nature of the services being provided to the Indian entity; and
- the broader commercial arrangement under which the Indian entity derived economic benefit from those personnel.
On that basis, the Court held that the arrangement amounted to a taxable service and that the assessee was liable for service tax for the normal period covered by the show cause notices.
Why the Ruling Matters for Businesses
The Northern Operating Systems judgment significantly altered how multinational groups assess secondment arrangements in India. It demonstrated that reimbursement without markup does not automatically insulate a transaction from indirect tax scrutiny. More importantly, it showed that contractual language alone will not decide the issue if the factual matrix suggests that the overseas entity continues to remain the substantive employer.
For businesses, this means secondment structures must be reviewed not only from an employment and payroll perspective, but also from an indirect tax advisory standpoint. In practice, the analysis often extends to documentation, contractual terms, control rights, reimbursement mechanics, and the wider business purpose of the deputation. This is also where support under indirect tax litigation and GST advisory and compliance becomes relevant.
Present Relevance Under GST
Although the Supreme Court ruling arose in the service tax regime, its reasoning has continued to influence GST-era investigations concerning employee secondment. At the same time, the position today is more nuanced than a plain reading of the judgment may suggest.
In December 2023, CBIC issued Instruction No. 05/2023-GST, clarifying that the Northern Operating Systems decision should not be applied mechanically in all cases. The instruction expressly noted that different secondment arrangements may carry different tax implications depending on the contractual and factual framework, and that each case requires a careful examination of its own matrix.
That makes the current position especially important for businesses: the judgment is highly relevant, but it is not a blanket rule for every secondment model. The real tax outcome continues to depend on how the arrangement is structured and evidenced.
