Infrastructure developers in India benefit from a comprehensive tax framework that combines profit-linked deductions under Section 80-IA with accelerated depreciation on eligible assets. The Direct Tax Code (DTC) 2025 preserves and enhances these benefits, with buildings for installing machinery and plant forming part of water supply projects or water treatment systems eligible for depreciation at 40% — a rate significantly higher than the general 10% rate for commercial buildings. This guide analyses the Section 80-IA-linked depreciation rules and their application to infrastructure developers.
The Section 80-IA Framework
Section 80-IA — Deduction for Infrastructure Development
Section 80-IA of the Income-tax Act, 1961 (as it existed prior to its repeal, with savings under the DTC) provides a 100% deduction of profits and gains derived from eligible infrastructure businesses for a specified period.
Key Features of Section 80-IA
- 100% deduction of profits for 10 consecutive years out of 15 years
- Available to enterprises engaged in developing, operating, and maintaining infrastructure facilities
- Infrastructure facilities include roads, bridges, ports, airports, water supply projects, and other specified facilities
Savings Clause
Under Section 536(2)(s) of the DTC, the deduction referred to in Section 80-IA of the repealed Income-tax Act shall, on fulfilment of the conditions, continue to be allowed under the DTC for tax years beginning on or after 1st April 2026.
Section 80-IA-Linked Depreciation Rates
Building for Water Supply/Treatment — 40%
Buildings acquired on or after 1st September 2002 for installing machinery and plant forming part of a water supply project or water treatment system which is put to use for the purpose of business of providing infrastructure facilities under Section 80-IA(4)(i) of the Income-tax Act, 1961 are eligible for depreciation at 40%.
This is significantly higher than the general rate of 10% applicable to other commercial buildings.
Infrastructure Buildings — Comparison
| Type of Building | Depreciation Rate |
|---|---|
| Residential buildings | 5% |
| Commercial buildings (general) | 10% |
| Water supply/treatment project buildings | 40% |
| Purely temporary erections | 40% |
Eligibility Conditions
1. Acquisition Date
The building must be acquired on or after 1st September 2002.
2. Use for Water Supply or Treatment

- Water supply project; or
- Water treatment system
3. Infrastructure Facility Status

Plant and Machinery for Infrastructure Facilities
General Rule
Machinery and plant other than those covered by special provisions are eligible for depreciation at 15%.
Special Provisions for Infrastructure
For machinery and plant acquired and installed on or after 1st September 2002 in a water supply project or a water treatment system put to use for the purpose of business of providing infrastructure facilities under Section 80-IA(4)(i), the depreciation rate is 40%.
Depreciation on Infrastructure Assets — Special Rules
Section 33(2) — Power Generation Assets
For assets of an undertaking engaged in generation or generation and distribution of power, the deduction in respect of depreciation shall be such percentage of its actual cost to the assessee, as may be prescribed.
Option for Power Generation Assets
The undertaking specified in Section 33(2) may, at its option, be allowed depreciation under sub-rule (1) read with Appendix I instead of the depreciation specified in Appendix II. Once exercised, the option is final and shall apply to all subsequent tax years.
Additional Depreciation
Additional depreciation of 20% (or 10% if used for less than 180 days) is available for new machinery or plant acquired and installed by an assessee engaged in the business of manufacture or production of any article or thing, or generation, transmission or distribution of power.
Practical Compliance for Infrastructure Developers

2. Calculate Depreciation

3. Claim Section 80-IA Deduction

- File separate audit report for each undertaking under Section 80-IA
4. Maintain Records
