The Draft Income-tax Rules, 2026 introduce significant clarity on how the income of non-residents will be determined when the exact amount accruing or arising in India cannot be precisely computed. Rule 9 provides the Assessing Officer (AO) with structured methods to calculate taxable income in such cases, ensuring effective tax administration while addressing practical challenges in cross-border transactions.
When Does Rule 9 Apply?
Rule 9 applies in situations where the Assessing Officer forms an opinion that the actual income of a non-resident cannot be definitely ascertained. This may arise where income is derived directly or indirectly through:
- Any asset or source of income in India
- Any property located in India
- Any business connection in India
Given the increasing complexity of global business models, digital transactions, and multinational operations, determining exact India-sourced income can sometimes be challenging. Rule 9 addresses this gap.
Methods Prescribed for Income Determination
If the income cannot be definitively computed, Rule 9 empowers the Assessing Officer to determine taxable income using one of the following methods:
1. Percentage of Turnover Method
The AO may calculate income at a reasonable percentage of the turnover accruing or arising in India. This method resembles presumptive taxation principles and may be used where turnover figures are available, but profit allocation is unclear.
2. Proportionate Profit Method
Income may be determined in proportion to the total profits and gains of the non-resident’s global business. Under this approach:
- Total profits are computed as per the Income-tax Act.
- The proportion of Indian receipts to total global receipts is applied to total profits.
This ensures a rational allocation of income attributable to India.
3. Any Other Suitable Method
Rule 9 also gives the AO residual authority to compute income “in such other manner as deemed suitable,” allowing flexibility in complex cases involving layered structures, transfer pricing issues, or indirect income streams.
Why Rule 9 is Important
The provision reinforces India’s source-based taxation framework. In cross-border taxation matters—especially where books of account are incomplete, unreliable, or not fully accessible—the tax department must rely on reasonable estimation mechanisms.
Key implications include:
- Greater scrutiny of non-resident business connections in India
- Increased documentation requirements for multinational entities
- Potential overlap with transfer pricing and attribution of profits rules
- Enhanced administrative discretion for tax authorities
However, the exercise of such discretion must align with principles of natural justice and be backed by reasoned orders to avoid arbitrary assessments.
Alignment with Global Tax Trends
Rule 9 reflects international practices where tax authorities estimate profits attributable to a jurisdiction in cases of incomplete data. With the rise of digital economy taxation and significant economic presence concepts, such estimation mechanisms are becoming increasingly relevant.
Conclusion
Rule 9 of the Draft Income Tax Rules, 2026, strengthens the framework for taxing non-residents where income attributable to India cannot be precisely determined. By providing structured yet flexible computation methods, it aims to balance revenue protection with administrative practicality.
Non-resident entities operating in India or having Indian-sourced income should carefully review their documentation, profit allocation models, and compliance frameworks in light of these proposed rules.
