Section 80LA: Tax Deduction for Offshore Banking Units and IFSC Units
Understand the eligible income, deduction percentages, ten-year and fifteen-year timelines, statutory definitions, and compliance requirements for qualifying units.
Reviewed: 10 October 2026
What is Section 80LA?
Section 80LA of the Income-tax Act, 1961 provided a profit-linked deduction for specified income earned by an eligible Offshore Banking Unit (OBU) in a Special Economic Zone (SEZ) or by an approved International Financial Services Centre (IFSC) unit. It is a deduction from eligible income included in gross total income, not a blanket exemption from tax on every receipt of a bank or financial institution.
The provision is especially relevant to offshore banking operations and authorised financial services activities in an IFSC. Qualification depends on the assessee's legal status, approvals, the nature of income and the applicable statutory version for the tax year.
Deduction amount and period under Section 80LA(1)
| Qualifying category | Deduction under the amended 1961 Act framework | Relevant point |
|---|---|---|
| Eligible scheduled bank or foreign bank having an Offshore Banking Unit in an SEZ | 100% of qualifying income for five consecutive assessment years, then 50% for the next five consecutive assessment years | Starting year is linked to the relevant regulatory permission |
| Qualifying IFSC unit | 100% of qualifying income for any ten consecutive assessment years chosen from a block of fifteen years | Choice and commencement are governed by the applicable version of section 80LA, including the permission or registration year |
Historical note: The earlier text gave IFSC units the same five-year 100% plus five-year 50% pattern. That should not be presented as the general IFSC rule after the legislative amendments. The exact assessment-year version and transition to the Income-tax Act, 2025 must be checked before filing a claim.
Which income qualifies? Section 80LA(2)
The eligible categories of income under the 1961 Act include:
- Section 80LA(2)(a): income from an Offshore Banking Unit in a Special Economic Zone.
- Section 80LA(2)(b): income from banking business of the kind referred to in section 6(1) of the Banking Regulation Act, 1949, with an SEZ undertaking or an undertaking that develops, operates or maintains an SEZ, as specified in the provision.
- Section 80LA(2)(c): income of an IFSC unit from the business for which it has been approved to operate in the centre.
- Additional specified IFSC activities: later amendments extended the provision to certain prescribed financial transactions and income categories, subject to their own statutory requirements. These must be tested against the applicable assessment-year text rather than assumed to qualify automatically.
Income outside the permitted and qualifying business should not be included merely because the taxpayer operates in an IFSC or SEZ.
Eligibility, approvals and compliance
Who may qualify?
Under section 80LA(1), an eligible offshore banking assessee includes a scheduled bank or a bank incorporated under the laws of a country outside India with an Offshore Banking Unit in an SEZ. The separate IFSC limb covers a qualifying unit of an International Financial Services Centre. The unit must hold the permissions, registrations or approvals required under the relevant regulatory law.
Section 80LA(3): audit report and documentary proof
The deduction is subject to the prescribed accountant's report certifying that it has been correctly claimed and to submission of the relevant regulatory permission or registration documentation as required by the applicable law and rules. Maintain segment-wise accounts, approvals, business commencement dates, computation workings and the records supporting the nature of qualifying income.
Return filing and other restrictions
Review the due-date requirements and deduction restrictions in the applicable income-tax legislation, including relevant Chapter VI-A rules and the prohibition on claiming the same income twice under incompatible incentives. The filing mechanism and forms may differ between assessment years.
The International Financial Services Centres Authority (IFSCA) is the unified regulator for financial products, services and institutions in India's IFSCs. Regulatory authorisation alone does not establish the tax deduction: the income-tax eligibility conditions must also be satisfied.
Meaning of important terms
International Financial Services Centre (IFSC)
The term takes its meaning from section 2(q) of the Special Economic Zones Act, 2005, as referenced in the explanation to section 80LA. An IFSC is a designated centre for permitted international financial services, subject to the relevant legal and regulatory framework.
Special Economic Zone (SEZ)
The term is defined in section 2(za) of the Special Economic Zones Act, 2005. It refers to a zone notified under the SEZ legislation.
Unit
As defined by section 2(zc) of the Special Economic Zones Act, 2005, the term covers the specified unit established within an SEZ under the statute.
Scheduled bank
Section 80LA references the definition in section 2(e) of the Reserve Bank of India Act, 1934. It generally refers to a bank included in the Second Schedule to that Act.
Offshore Banking Unit (OBU)
An OBU is a banking unit authorised to conduct permitted offshore banking business within the statutory and regulatory framework. Merely maintaining a foreign-currency account does not make an entity an eligible OBU.
Illustrative deduction calculation
Assume a qualifying IFSC unit has eligible business profits of Rs. 4 crore in an assessment year falling within its valid ten-year deduction selection period. At a 100% deduction rate, the illustrative deduction is Rs. 4 crore, subject to the statutory computation, approvals and other limitations. Non-qualifying income must be excluded.
For a qualifying OBU with eligible profits of Rs. 4 crore, the illustrative deduction would be Rs. 4 crore during its applicable 100% period and Rs. 2 crore during its applicable 50% period. These examples do not determine eligibility under the post-2026 legislation.
Official legislation and regulatory references
Consult the India Code for the Income-tax Act, 1961, the Income-tax Act, 2025, the SEZ Act, 2005 and the Banking Regulation Act, 1949; the Income Tax Department for tax legislation and guidance; the Income Tax e-Filing Portal for forms and filing; the IFSCA for IFSC authorisations; and the SEZ India portal for the SEZ framework.
For assessment years governed by the 1961 Act, examine the precise version of section 80LA in force for that year. For tax years beginning on or after 1 April 2026, examine the corresponding provisions of the Income-tax Act, 2025 and applicable transition rules.
Frequently asked questions
Does every IFSC business receive a 100% income-tax deduction?
No. The unit and income must meet the specific statutory conditions, hold appropriate approvals and fall within the applicable deduction period.
What is the difference between the OBU and IFSC deduction periods?
Under the amended 1961 Act framework, an eligible OBU generally had five years at 100% followed by five years at 50%, while an eligible IFSC unit could claim 100% for ten consecutive years selected from fifteen years.
Can a unit claim section 80LA without regulatory permission?
No. The required permission, registration or approval and other statutory conditions must be satisfied.
Is the deduction calculated on total turnover?
No. It is based on eligible income or profits determined under the relevant statutory rules, not gross receipts.
