Mastering Double Taxation Relief in India: A Deep Dive into Sections 90 and 91
Double taxation is a significant concern for individuals and businesses engaged in cross-border
transactions. It occurs when the same income is taxed in two jurisdictions, leading to higher tax
burdens and reduced profitability. For instance, if an Indian resident earns income abroad, that
income might be taxed both in the foreign country where it is earned and in India, where the
individual resides.
To alleviate this burden and promote international trade and investment, India’s Income Tax Act,
1961, incorporates provisions for double taxation relief through Section 90 and Section 91. These
sections aim to eliminate or mitigate the adverse effects of double taxation, ensuring taxpayers do
not pay more than their fair share of taxes.
Understanding these sections is crucial for Indian taxpayers involved in global operations, as it helps
them maximize tax efficiency and comply with both domestic and international tax regulations. This
article provides an in-depth explanation of Sections 90 and 91, their application, and a comparative
analysis to clarify their role in resolving double taxation issues.
Understanding Section 90
Section 90 applies to cases where India has entered into a Double Taxation Avoidance Agreement
(DTAA) with another country. A DTAA is a bilateral agreement between two nations aimed at
preventing double taxation of income and fostering economic cooperation.
Under this section, taxpayers can avail relief in two ways:
- Exemption Method: Income is taxed only in one of the two countries, as per the DTAA
terms. For example, if the DTAA specifies that a certain type of income (e.g., royalties) is
taxable only in the source country, the resident country will not tax that income. - Tax Credit Method: If income is taxable in both countries, the taxpayer can claim a credit for
the tax paid in the source country against their tax liability in the resident country.
The DTAA provisions vary by country, and taxpayers need to comply with the specific treaty terms to
claim relief. A Tax Residency Certificate (TRC) is typically required to prove Indian residency and
claim benefits under the DTAA.
Understanding Section 91
Section 91 comes into play when India does not have a DTAA with the country where the income is
earned. This provision offers unilateral relief, meaning India provides relief for taxes paid in the
foreign country without requiring a bilateral agreement.
Under Section 91, taxpayers can claim a tax credit for the amount of tax paid abroad, subject to
certain limits. The credit is allowed up to the lower of:
The foreign tax paid on the income.
The Indian tax payable on the same income.
This unilateral relief mechanism ensures that Indian taxpayers are not penalized in the absence of a
DTAA, making it a vital provision for individuals and businesses earning income in non-DTAA
countries.
Comparison: Section 90 vs. Section 91
Aspect Section 90 Section 91
Scope Applies when India has a DTAA with
another country.
Applies when no DTAA exists
between India and the other
country.
Relief Mechanism Relief is based on the DTAA terms
(exemption or tax credit).
Relief is provided through
unilateral tax credit under
domestic law.
Eligibility Taxpayer must be a resident of India
and earn income taxable in both India
and the DTAA partner country.
Taxpayer must be a resident of
India earning income from a non-
DTAA country.
Type of Relief May include: Tax credit up to:
- Exemption method: Income taxed
only in one country. - Indian tax liability on foreign
income or foreign tax paid,
whichever is lower. - Tax credit method: Foreign tax
credited against Indian tax liability.
Documentation
Required
Tax Residency Certificate (TRC), proof
of foreign tax payment, and DTAA
provisions.
Proof of foreign tax payment and
income details.
Flexibility Governed by the terms of the DTAA,
which may vary by country.
Relief is standardized under Indian
tax law, offering simplicity in the
absence of a treaty.
Key Differences and Practical Implications
- DTAA Dependency: Section 90 relies on the existence of a DTAA, providing customized relief
options based on agreements between India and the partner country. Section 91, on the
other hand, is independent of treaties, ensuring taxpayers benefit even in non-DTAA
scenarios. - Relief Mechanisms: DTAAs under Section 90 often offer greater flexibility with exemption
options, whereas Section 91 strictly provides tax credits. - Documentation and Compliance: Claiming relief under Section 90 involves adhering to
treaty-specific documentation and compliance requirements, such as obtaining a TRC.
Section 91 offers a simpler process as it is governed by domestic law.
Importance of Double Taxation Relief
Double taxation relief is essential for fostering global economic integration and ensuring fairness in
taxation. It reduces the tax burden on international income, promotes cross-border investments,
and encourages individuals and businesses to expand globally.
Indian taxpayers must carefully assess whether their situation is covered under Section 90 or 91 to
determine the appropriate relief mechanism. Seeking professional advice and maintaining accurate
documentation is crucial for maximizing benefits and avoiding compliance issues.
Conclusion
Sections 90 and 91 of the Income Tax Act serve as powerful tools to address the issue of double
taxation. While Section 90 leverages international agreements to provide customized relief, Section
91 ensures a fallback mechanism in the absence of such treaties. Together, these provisions align
India’s tax framework with global best practices, supporting taxpayers engaged in international
activities.
For taxpayers navigating the complexities of cross-border taxation, understanding these sections is
the key to optimizing tax obligations and fostering financial efficiency. Whether dealing with DTAA-
covered income or foreign earnings from a non-treaty country, these provisions ensure fair and
equitable treatment for Indian residents.
