Section 46 of the IT Act 2025 allows businesses in 14 designated priority sectors to claim a 100% deduction on eligible capital expenditure. The provision is optional, covers sectors ranging from cold chain facilities to semiconductor manufacturing and infrastructure projects, and comes with strict conditions on depreciation, cash payments, asset holding period, and loss set-off.

Section 46 of the Income Tax Act, 2025 provides a significant tax benefit for businesses classified as specified businesses. Under this section, an assessee may claim a 100% deduction on eligible capital expenditure incurred for such businesses, subject to the prescribed conditions. The provision is optional — the assessee may choose whether or not to claim the deduction in any given tax year.
Section 46 is designed to encourage investment in certain priority sectors by allowing eligible businesses to claim an immediate 100% deduction for qualifying capital expenditure, rather than depreciating it over multiple years under the normal depreciation schedule.
Specified businesses are those activities expressly covered under Section 46. If a business falls within the notified list and satisfies the applicable conditions, the capital expenditure incurred for that business may qualify for the deduction. The following table summarises the 14 eligible specified businesses along with their respective commencement dates:
| S.No. | Specified Business | Commencement On or After |
|---|---|---|
| 1 | Setting up and operating a cold chain facility | 01-04-2009 |
| 2 | Setting up and operating a warehousing facility for agricultural produce | 01-04-2009 |
| 3 | Laying and operating a cross-country pipeline for distribution of petroleum oil and natural gas (Only Indian companies, consortium, or authority/board/corporation/body established by a Central or State Act; must be approved by the Petroleum and Natural Gas Board) | Natural gas: 01-04-2007 | Petroleum oil: 01-04-2009 |
| 4 | Building and operating a 2-star hotel or above | 01-04-2010 |
| 5 | Building and operating a hospital with 100 beds or more | 01-04-2010 |
| 6 | Developing and building a housing project under a slum redevelopment scheme | 01-04-2010 |
| 7 | Developing and building a housing project under an affordable housing scheme | 01-04-2011 |
| 8 | Production of fertilizers in India | 01-04-2011 |
| 9 | Setting up and operating an inland container depot or container freight station | 01-04-2012 |
| 10 | Bee keeping and production of bee's honey and wax | 01-04-2012 |
| 11 | Setting up and operating a warehousing facility for sugar | 01-04-2012 |
| 12 | Laying and operating a slurry pipeline for transportation of iron ore | 01-04-2014 |
| 13 | Setting up and operating a semi-conductor wafer fabrication manufacturing unit | 01-04-2014 |
| 14 | Operating, developing and maintaining a new infrastructure facility | 01-04-2017 |
If the asset on which Section 46 deduction was claimed is used for non-specified business purposes before the 8-year lock-in period expires, the earlier deduction is partially clawed back. The amount that becomes taxable under the head PGBP is determined as follows:
| Amount of Deduction claimed under Section 46 | XXX |
| Less: Depreciation allowable (had the asset been depreciated instead) | (XXX) |
| Amount taxable under PGBP | XXX |
Further, the cost of acquisition of the asset for the purpose of the non-specified business going forward shall be computed as follows:
| Amount of Deduction claimed under Section 46 | XXX |
| Less: Depreciation allowable for non-specified business | (XXX) |
| Cost of Acquisition for non-specified business | XXX |
Early diversion of the asset to non-specified business purposes before 8 years triggers a dual consequence: (1) a partial recapture of the earlier Section 46 deduction as PGBP income, and (2) a reduced cost of acquisition for the asset in the non-specified business. Plan asset usage carefully before claiming the deduction.
| Profits from the specified business of new hotel in Madurai (before Section 46 deduction) | ₹25,00,000 |
| Less: Deduction u/s 46 — | |
| Capital expenditure incurred during TY 2026-27 (₹200 lakh less ₹150 lakh being cost of land — excluded) | ₹50,00,000 |
| Capital expenditure prior to 1.4.2026, incurred Jan–Mar 2026 (capitalised on 1.4.2026, deductible in year of commencement) | ₹50,00,000 |
| Total deduction allowable under Section 46 | ₹1,00,00,000 |
| Loss from the specified business of new hotel in Madurai | (₹75,00,000) |
| Add: Profit from the existing specified business — four-star hotel in Coimbatore | ₹1,20,00,000 |
| Net profit from PGBP after set-off of specified business loss under Section 114 | ₹45,00,000 |
Key observations from the illustration: (1) The ₹50 lakh pre-commencement expenditure (January–March 2026, capitalised on 1 April 2026) is fully deductible in TY 2026-27 under condition 2 — it is treated as incurred in the year of commencement. (2) The ₹150 lakh land cost is expressly excluded from the Section 46 deduction and receives no deduction. (3) The ₹75 lakh loss from the Madurai hotel is eligible for set-off against the ₹120 lakh profit from the Coimbatore hotel under Section 114, since both are specified businesses (hotels).
No. The deduction is entirely optional. An assessee engaged in a specified business may choose whether or not to claim the deduction under Section 46, depending on the overall tax position and the long-term implications — particularly the permanent trade-off against future depreciation. If the deduction is not claimed, the normal depreciation schedule under the Act will apply to the qualifying asset.
No. If a deduction under Section 46 is claimed on a particular capital expenditure, depreciation on that same expenditure is not allowed either in the same year or in any future year. This is a permanent restriction — once the Section 46 route is chosen for an asset, the depreciation benefit is lost for the entire life of that asset.
If the asset is diverted to non-specified business purposes before the 8-year lock-in period expires, the earlier deduction claimed under Section 46 is partially reversed. The clawback amount — computed as the deduction claimed minus notional depreciation allowable — becomes taxable as PGBP income in the year of diversion. Additionally, the residual amount (after reducing the notional depreciation) is treated as the cost of acquisition of the asset for the non-specified business going forward.
Section 46 can be highly beneficial for eligible businesses because it permits an immediate 100% deduction of qualifying capital expenditure — effectively a full write-off in the year of incurrence or commencement. However, the benefit comes with important restrictions, particularly in relation to depreciation, cash payment limits, asset holding period, and loss set-off rules. For taxpayers engaged in specified businesses, Section 46 may offer significant tax planning opportunities when used judiciously. Before claiming the deduction, it is important to verify whether the business qualifies as a specified business, whether the expenditure falls within the eligible categories, and whether all prescribed statutory conditions have been fulfilled — including mandatory audit under Section 63.
