When Sikkim merged with India in 1975, special constitutional protections were preserved under Article 371F. To honor historical arrangements and safeguard the interests of indigenous residents, Parliament introduced Section 10(26AAA) of the Income-tax Act.
Under Section 10(26AAA), a Sikkimese individual is exempt from income tax on:
- Income arising from any source within Sikkim.
- Dividend income.
- Interest on securities.
The exemption applies only to individuals recognized as “Sikkimese” under the statutory definition provided in the Act.
Why is Sikkim Exempt from Income Tax?
Several historical and constitutional factors contributed to the exemption:
1. Historical Merger Agreement
Sikkim was an independent kingdom before joining India in 1975. Special protections were guaranteed to preserve the rights of its residents.
2. Constitutional Protection
Article 371F grants special constitutional safeguards to Sikkim and its people.
3. Preservation of Indigenous Rights
The tax exemption was designed to protect the economic interests of indigenous Sikkimese communities.
4. Judicial Recognition
The Supreme Court and subsequent legislative amendments expanded protection to certain old settlers and clarified the scope of the exemption.

Common Misconceptions
Myth: Nobody in Sikkim pays income tax.
Reality: The exemption applies only to eligible Sikkimese individuals as defined by law. Others may still be subject to income tax.
Myth: Every resident of northeastern states is exempt.
Reality: Only qualifying Scheduled Tribe members residing in specified areas can claim exemption under Section 10(26).
Myth: Tribal-owned companies are automatically tax-free.
Reality: The exemption generally applies to qualifying individuals, not companies, firms, or associations merely because their members belong to Scheduled Tribes.
India’s income tax system contains unique constitutional and statutory exemptions designed to protect historically distinct communities. Sikkim enjoys a special position through Section 10(26AAA), making eligible Sikkimese individuals largely exempt from income tax. Meanwhile, Scheduled Tribe members in Assam, Arunachal Pradesh, Manipur, Mizoram, Nagaland, Tripura, and Ladakh receive targeted relief under Section 10(26). These provisions reflect India’s commitment to preserving cultural identity while promoting equitable economic development.
