Special Tax Regimes—A Comprehensive Analysis

This analysis provides a statutory and strategic examination of the parallel structures of tax concessions extended across the primary categories of assessees: non-corporate entities (Individuals, HUF, AOP, BOI, AJP) under Section 115BAC, corporate assessees under Sections 115BAA and 115BAB, and co-operative societies under Sections 115BAD and 115BAE of the Income Tax Act.

The following table provides a reference point, summarizing the lowest available base concessional rates across the major assessee categories, which illustrates the substantial magnitude of the rate reduction achieved through these specialized sections compared to the standard maximum corporate rate of 30%.

Key Concessional Base Rate Comparison Matrix (AY 2024-25)

I. Non-Corporate Assessees: Section 115BAC (Individuals, HUF, AOP, BOI, AJP)

A. Statutory Evolution and Applicability

The New Tax Regime, introduced under Section 115BAC of the Income Tax Act, 1961, represents the most pivotal structural reform for non-corporate assessees. The refined regime under Section 115BAC(1A) was incorporated by the Finance Act 2023 and has been formally designated as the default method of taxation starting from the Financial Year 2023-24 (Assessment Year 2024-25).

This means that individuals, Hindu UndividedFamilies (HUF), Association of Persons (AOP, excluding co-operative societies), Body of Individuals (BOI), and Artificial Juridical Persons (AJP) are automatically subjected to the 115BAC tax calculation unless they proactively choose to opt out of it.

B. Tax Structure and Rates under Section 115BAC(1A) (AY 2024-25 Statutory)

The Section 115BAC regime is characterized by a significantly modified slab system featuring a higher basic exemption limit and a greater number of progressive income brackets compared to the traditional structure. The statutory slab schedule enacted by the Finance Act 2023 is applicable for the Assessment Year 2024-25.

New Tax Regime (Section 115BAC) Slabs (AY 2024-25 Statutory)

The Finance Act 2023 also increased the rebate available under Section 87A, resulting in taxable income up to ₹7 lakh being effectively tax-free under this new regime for AY 2024-25. While the statutory rates apply for the current year, it should be noted that proposed revisions for future financial years, such as FY 2025-26, project a potential increase in the basic exemption limit to ₹4 lakh and a revised structure where the highest 30% slab may only apply to income above ₹24 lakh.

C. Key Deductions and Exemptions Retained

The new regime preserves certain essential benefits, particularly those associated with the compulsory costs of earning employment income or statutory employer obligations:

1. Standard Deduction: A standard deduction of ₹50,000 is explicitly available for salaried employees and pensioners under Section 115BAC for AY 2024-25. (It should be noted that this amount is sometimes projected to rise to ₹75,000 in future years based on anticipated revisions , but the statutory AY 2024-25 rate is ₹50,000).
2. Statutory Contributions: The employer's contribution to the National Pension Scheme (NPS) under Section 80CCD(2), up to 14% of the salary, is preserved.
3. Specific Allowances: The transport allowance for specially-abled employees, conveyance allowance for job-related travel, and daily allowances for duty-related expenses remain exempt under specific conditions.
4. Property and Pension Income: Interest paid on housing loans for let-out property (Section 24) and the deduction available for family pension income (Section 57(iia)) are also retained.

Benefits such as the standard deduction and 80CCD(2) confirms that the legislative objective of the new regime is to systematically eliminate incentives linked to discretionary personal savings (like 80C and 80D), while retaining benefits related to mandatory or necessary costs incurred to generate income.

D. Compliance for Opting Applicable Tax Regime

The procedure for electing or changing the applicable tax regime differs critically based on the nature of the assessee's income.

Non-Business Income Assessees

Assessees (Individuals, HUF, AOP, BOI, or AJP) who do not have income from business or profession are afforded maximum flexibility. They can choose between the Old and New Regimes on an annual basis simply by exercising the option directly within their Income Tax Return (ITR 1 or ITR 2). The return must be filed by the due date specified under section 139(1) of the Income Tax Act. No separate prescribed form is required to opt out or re-enter the 115BAC regime.

Business Income Assessees (B&P)

Taxpayers with income derived from business or profession are subject to more stringent conditions to manage the complexities related to the carry-forward of depreciation and losses. These assessees must file Form 10-IEA to communicate their decision to opt out of the default new regime or to subsequently re-enter the new scheme. This form must be submitted by the due date specified under section 139(1) of the Income Tax Act.

A critical statutory restriction applies specifically to B&P assessees: they possess only a one-time option to switch back from the new regime to the old regime. Once this one-time switch has been utilized, the assessee is permanently locked into the old regime and forfeits the ability to opt back into 115BAC in any subsequent financial year.

II. Analysis: Old Regime vs. New Regime (115BAC)

A. Critical Comparison and Break-Even Point Determination

Determining the optimal tax regime requires a detailed quantitative assessment tailored to the specific income profile and the quantum of deductions utilized by the individual taxpayer.

The primary advantage of the New Regime lies in its reduced marginal rates and the significantly enhanced Rebate under Section 87A. For AY 2024-25, the taxable income up to ₹7 lakh is effectively rendered tax-free due to this rebate.

This effective zero-tax threshold makes the New Regime highly attractive and often superior for middle-income salaried taxpayers who historically claim minimal statutory deductions.

The fundamental strategic decision rests on whether the financial benefit derived from forgone deductions (HRA, 80C, 80D, etc.) is greater than the tax savings provided by the New Regime's lower marginal rates.

For high-income taxpayers (those with gross income exceeding ₹25 lakh), the Old Regime is only likely to prove more beneficial if the total quantum of available deductions and exemptions exceeds a crucial threshold, estimated to be around ₹8,00,000.

For salaried individuals in the mid-to-high income brackets (e.g., ₹10 lakh to ₹15 lakh salary), the quantum of deductions required to favor the Old Regime is substantial. This threshold is typically only surpassed if the taxpayer utilizes the full statutory limit under Section 80C (₹1.5 lakh), claims significant interest deductions on a self-occupied housing loan (up to ₹2 lakh), and maximizes health insurance benefits under Section 80D. The New Regime is generally the more efficient choice for taxpayers whose aggregate deductions fall below approximately ₹3 lakh, confirming its effectiveness for individuals with simplified financial structures.

B. Comparative Tax Liability (Illustrative AY 2024-25)

The following model illustrates how the utilization of common deductions can strategically shift the comparative tax liability for a salaried individual earning a gross income of ₹10,00,000 in AY 2024-25, based on scenarios where significant deductions are claimed in the Old Regime.

Comparative Tax Liability: Old vs. New Regime (AY 2024-25, ₹10L Salary)

The analysis confirms that even for an income level where the marginal rates start to increase rapidly, if the individual successfully utilizes substantial deductions (in this case, ₹2,00,000 under Chapter VI-A plus HRA and Professional Tax benefits), the Old Regime still provides a lower net tax liability.

III. Taxation of Specific Non-Corporate Entities: AOP, BOI, and AJP

A. Standard Tax Liability and Surcharge

For the collective non-corporate entities—Association of Persons (AOP, excluding co-operative societies), Body of Individuals (BOI), and Artificial Juridical Persons (AJP)—the standard taxation method generally applies the same progressive slab rates applicable to individuals, with a maximum marginal rate of 30% for income exceeding ₹10 lakh. These entities are also eligible to adopt the New Tax Regime under Section 115BAC of the Income Tax Act.

Applicable Surcharge Rates for AOP/BOI/AJP (Old Regime)

The Health and Education Cess (HEC) at 4% is applied universally on the income tax plus surcharge, irrespective of the regime selected.

B. Maximum Marginal Rate (MMR) Provisions

To guard against the potential for tax avoidance or income fragmentation within AOP/BOI structures, the Income Tax Act includes specific provisions that mandate the taxation of their income at the Maximum Marginal Rate (MMR). The base MMR is defined as 30% plus the highest applicable surcharge and cess.

The income of an AOP or BOI is assessed at the MMR under two primary statutory safeguards:

1. Indeterminate Shares: If the shares of the members in the total income of the AOP/BOI are not determined or are unknown, the entire income is automatically assessed at the Maximum Marginal Rate.
2. High-Income Members: Even in cases where the members' shares are clearly determinate, the AOP/BOI's income is still assessed at the Maximum Marginal Rate if the total income of any single member exceeds the basic exemption limit (i.e., the maximum amount not subject to income tax).

These statutory conditions, by applying the MMR to AOP/BOI income in scenarios of ambiguity or where members are themselves high-income individuals, function as a critical anti-abuse mechanism. This prevents the utilization of these collective entities by high-net-worth members to park income at a lower rate than their highest personal marginal rate, thereby enforcing the principle that the income must be taxed at the highest attributable rate within the structure.

C. Alternate Minimum Tax (AMT) Applicability

AOPs and BOIs are subject to the provisions of the Alternate Minimum Tax (AMT) regime. If the adjusted total income of an AOP/BOI surpasses the threshold of ₹20 lakh, it becomes liable to pay AMT at a rate of 18.5% of the adjusted total income (plus surcharge and cess). This liability is triggered when the normal income tax payable by the entity is less than 18.5% of its adjusted total income. The complex interaction of MMR and AMT often makes adopting the simplified 115BAC regime, which typically exempts these entities from AMT, a sound strategic choice.

IV. Concessional Corporate Tax Regimes for Domestic Companies

The legislature introduced Sections 115BAA and 115BAB specifically to stabilize corporate investment by providing distinct concessional regimes designed to ensure a low and certain tax base for domestic companies.

A. Section 115BAA: The Standard Low-Rate Option

Section 115BAA offers a reduced tax rate primarily targeting existing domestic companies. This provision, inserted in 2019, aimed to stimulate corporate investment and global competitiveness.

Applicable Rate and Effective Tax Rate (ETR)

Domestic companies opting for this section pay income tax at a base rate of 22%. This rate is subject to a flat surcharge of 10%, which applies uniformly regardless of the company's total income. Including the 4% HEC, the resulting Effective Tax Rate (ETR) is 25.17%. This ETR is generally far more favorable than the ETRs applicable to standard corporate tax rates, which can range up to 29.12% or 34.94% for high-income companies.

Compliance and Permanence

The election for 115BAA must be formally exercised before the due date for filing the income tax return for the relevant assessment year. A paramount condition of this regime is its irrevocability: once the company opts for 115BAA, it is permanently locked in and cannot revert to the standard corporate tax rate of 30% in subsequent years.

Key Advantage

A significant fiscal benefit of choosing Section 115BAA is the explicit exemption from the provisions of Minimum Alternate Tax (MAT) under Section 115JB of the Income Tax Act.

B. Section 115BAB: Incentive for New Manufacturing Companies

Section 115BAB provides the lowest corporate tax rate, intended solely as a powerful incentive to encourage new, greenfield investments in domestic manufacturing.

Highly Concessional Rate

Qualifying new manufacturing companies under this section benefit from an exceptionally low base tax rate of 15%. After applying the flat 10% surcharge and 4% HEC, the effective tax rate stabilizes at approximately 17.16%.

Eligibility and Conditions

Access to the 15% rate is conditional upon meeting strict statutory requirements:

1. The company must be a new domestic company incorporated on or after October 1, 2019.
2. It must commence manufacturing or production activities on or before March 31, 2023.
3. The company must be predominantly engaged in the business of manufacturing or production.
4. It must adhere to specific restrictions regarding the use of second-hand plants and machinery.
5. Any income derived from sources that are not related to or incidental to the manufacturing or production activities is taxed at a higher rate of 22%.
6. This option is also irrevocable once exercised before the ITR due date.

C. Specific Forfeited Benefits (Common to 115BAA and 115BAB)

The reduced corporate tax rates necessitate the mandatory abandonment of several investment and operational statutory incentives. Both 115BAA and 115BAB require companies to compute their total income without claiming a comprehensive list of deductions and exemptions, which include:

1. Deduction for SEZ Units: Forgoing the deduction available to companies established in Special Economic Zones (SEZs) under Section 10AA.
2. Accelerated Depreciation: The claim for additional depreciation under Section 32(1)(iia) is disallowed. Standard depreciation under Section 32 remains eligible.
3. Investment Allowances: Forgoing investment allowance under Section 32AD for machinery installed in notified backward areas.
4. Scientific Research: Deductions for expenses related to scientific research, including payments made to specified research associations or universities under Section 35.
5. Capital Expenditure Incentives: Claims for specified capital expenditure deductions under Section 35AD.
6. Other Chapter VI-A Deductions: Most deductions under Chapter VI-A (e.g., 80IA, 80IB) are disallowed, with the notable exception of the deduction for new employment generation under Section 80JJAA.
7. Unabsorbed Losses: The ability to offset any carried-forward loss or unabsorbed depreciation from prior years is disallowed if such losses were specifically attributable to the forgone deductions listed above.

The mandatory requirement to sacrifice accelerated depreciation and R&D benefits suggests that 115BAA and 115BAB are strategically less suitable for companies operating in highly capital-intensive industries (e.g., heavy infrastructure) or those relying heavily on substantial domestic scientific research and development activities.

These firms must acknowledge that the higher standard statutory rate (30%), combined with the ability to claim substantial capital expenditure and R&D deductions, might still result in a lower effective tax burden over the long term than the fixed 25.17% ETR under 115BAA of the Income Tax Act.

D. Comparative Corporate Tax Rates for Domestic Companies

The strategic determination for domestic companies must carefully balance the stability and certainty of a fixed, low rate against the potential for higher, but deduction-dependent, tax savings under the standard regime.

V. Special Tax Regimes for Resident Co-operative Societies

The Indian cooperative sector has been structurally aligned with corporate taxation through parallel tax concession schemes, recognizing the sector's economic contribution and importance.

A. Section 115BAD: General Reduced Rate

Section 115BAD, effective from the Financial Year 2020-21, provides a reduced tax rate option for general resident co-operative societies.

Tax Rate and Compliance

Societies electing this regime are taxed at a base rate of 22%. This is subject to a flat surcharge of 10%. Like the corporate concessions, the decision to opt for 115BAD is irrevocable.

Forfeiture and Benefits

In exchange for the 22% rate, societies must abandon certain specified deductions, including those related to SEZ operations, additional depreciation, and scientific research. A notable benefit is the exemption from paying the Alternate Minimum Tax (AMT), which simplifies compliance relative to the general AMT liability for collective bodies like AOP/BOI.

B. Section 115BAE: Concession for New Manufacturing Co-operative Societies

Section 115BAE offers the lowest tax rate within the co-operative sector, specifically targeting new manufacturing enterprises, effective from the Financial Year 2024-25.

Lowest Rate and Eligibility

This section provides a highly competitive base rate of 15% (plus flat 10% surcharge). The eligibility criteria are stringent and designed to focus on new ventures:

1. The society must be newly incorporated on or after April 1, 2023.
2. It must be resident in India.
3. It must be engaged exclusively in the business of manufacturing, production, or the generation of electricity.
4. The society must forgo other exemptions and deductions under the Act.

This legislative strategy, creating Section 115BAE (15% for new co-operatives) parallel to Section 115BAB (15% for new companies), is a significant policy action.

It grants new manufacturing co-operatives parity with newly incorporated domestic companies, providing tax neutrality for new manufacturing investments regardless of whether the structure is corporate or cooperative. Co-operative societies choosing Section 115BAE are not liable for Alternate Minimum Tax (AMT).

VI. Conclusion

The comprehensive framework encompassing Sections 115BAC, 115BAA, 115BAB, 115BAD, and 115BAE confirms a fundamental, coordinated legislative convergence toward a simplified, low-rate, low-exemption tax model across the Indian economy.

• Individuals and HUF (115BAC): This default regime is optimal for the vast majority of taxpayers. The combined benefit of lower marginal rates and the enhanced Section 87A rebate makes it superior unless the quantum of forgone deductions (80C, 80D, SOP interest, HRA) represents a critical mass, generally exceeding 30% to 40% of taxable income.
• Domestic Companies (115BAA/BAB): The 15% rate under 115BAB is overwhelmingly beneficial for new manufacturing entities. The 25.17% ETR under 115BAA is advantageous for service-oriented companies or those with high profitability and intrinsically low capital expenditure requirements. Crucially, companies with substantial R&D claims, or reliance on accelerated depreciation, must recognize that these capital-related deductions may offer a greater lifetime tax shield under the standard regime than the guaranteed, albeit lower, fixed rate of 115BAA.
• AOP, BOI, and AJP: Due to the complexity of the standard regime, including the statutory safeguards that trigger the Maximum Marginal Rate and the applicability of the Alternate Minimum Tax (AMT), defaulting to the New Regime (115BAC) usually offers superior compliance simplicity and rate predictability.

Consequently, taxpayers must strategically reorient their financial and organizational planning. Future planning should rely less on complex, deduction-based tax avoidance methods and instead focus on operational efficiency and capitalizing on the statutory efficiency provided by the concessional rate structures.
