Direct Tax Code 2025: Guide to the New Default Tax Regime (Sec 115BAC)

Quick Answer

Expert CA analysis on the transition from the Income Tax Act 1961 to the Direct Tax Code 2025, focusing on the new default tax regime under Section 115BAC and the loss of tax exemptions.

Key Takeaways

  • Default Regime is the New Norm: The new tax regime, introduced via Section 115BAC of the Income Tax Act, 1961, is now the default option for individuals and HUFs as of Assessment Year 2024-25. Taxpayers must consciously opt-out if they wish to follow the old regime. This philosophy of a simplified, default tax system with lower rates and fewer exemptions is expected to be a cornerstone of the proposed Direct Tax Code 2025.
  • Significant Forfeiture of Exemptions: Choosing the default new regime necessitates forgoing a majority of commonly claimed deductions and exemptions. This includes House Rent Allowance (HRA), Leave Travel Allowance (LTA), and most deductions under Chapter VI-A such as those under Sections 80C, 80D, and 80TTA.
  • Selective Deductions Retained: Despite the large-scale removal of exemptions, a few key deductions are still permissible under the new default regime. These include the standard deduction of ₹50,000 from salary income and the employer's contribution to the National Pension System (NPS) under Section 80CCD(2).
  • Annual Flexibility for Most Taxpayers: Individuals without business income have the flexibility to switch between the new and old tax regimes each financial year, allowing them to choose the more beneficial option based on their financial situation for that year. However, those with business income have limited opportunities to switch back to the old regime once they have opted for the new one.

PART 1: EXECUTIVE SUMMARY

This compliance guide provides a detailed analysis of the transition towards a new default tax regime, a principle established by Section 115BAC of the Income Tax Act, 1961, and anticipated to be the foundation of the forthcoming Direct Tax Code (DTC) 2025. The core objective of this shift is to simplify the direct tax structure, offering lower slab rates in exchange for the surrender of most tax exemptions and deductions.

  • The Old Law (1961): The traditional tax system, now referred to as the "old regime," allowed taxpayers to reduce their taxable income by claiming a wide array of deductions and exemptions. These included benefits for house rent, travel, investments under Section 80C (like PPF, life insurance), health insurance premiums under 80D, and more. This structure, while beneficial for those who made specific investments, contributed to the complexity of tax compliance.

  • The New Law (2025): The new framework, currently embodied by Section 115BAC, has been made the default tax regime from the Financial Year 2023-24 (Assessment Year 2024-25). This regime features more attractive, lower tax slab rates but disallows approximately 70 common exemptions and deductions. The proposed Direct Tax Code 2025 is expected to build upon this foundation, aiming to create a modern, transparent, and simplified tax system by further reducing exemptions and streamlining compliance.

  • Who is Impacted: This transition affects all individual taxpayers, including salaried persons, professionals, and Hindu Undivided Families (HUFs). It is most significant for salaried individuals who previously structured their finances around claiming deductions like HRA, LTA, and Section 80C benefits. Taxpayers with minimal investments or those who prefer a straightforward tax calculation may find the new default regime more advantageous. A careful comparison is necessary for every taxpayer to determine the most beneficial regime for their specific circumstances.


PART 2: DETAILED TAX ANALYSIS

1. Background & Legal Context

The introduction of Section 115BAC by the Finance Act, 2020, marked a pivotal shift in India's personal taxation policy. This provision introduced an optional, alternative tax regime with lower tax rates, conditional upon the taxpayer forgoing a specified list of deductions and exemptions. The legislative intent was to simplify the tax code, reduce compliance burdens, and provide relief to taxpayers who were unable to utilize the full spectrum of available deductions.

With effect from the Assessment Year 2024-25, the Finance Act, 2023, designated this new tax regime under Section 115BAC as the default regime. This means all individual taxpayers are automatically placed under this regime unless they specifically choose to opt out and be taxed under the old, conventional system. This move is a clear precursor to the principles expected to govern the proposed Direct Tax Code (DTC) 2025. The DTC aims to replace the aged Income Tax Act, 1961, with a simpler, more modern framework characterized by reduced exemptions, rationalized tax rates, and enhanced transparency. The default nature of Section 115BAC is a foundational step in acclimatizing taxpayers to a system with fewer tax-saving exemptions.

2. Statutory Mapping: 1961 Act vs 2025 Act

The transition effectively creates two parallel systems under the current Act, with the new system setting the stage for the proposed DTC 2025.

Provision/FeatureOld Tax Regime (Optional)New Default Regime (Sec 115BAC)Anticipated in Direct Tax Code 2025
Basic Exemption Limit₹2,50,000 (below 60 years), ₹3,00,000 (60-80 years), ₹5,00,000 (>80 years)Uniform ₹3,00,000 for all individuals.Expected to maintain a simplified, uniform exemption limit.
Tax Slabs & RatesHigher rates, fewer slabs.Lower rates across multiple slabs. For FY 2024-25, income from ₹3-7 lakh is taxed at 5%, ₹7-10 lakh at 10%, etc.A streamlined structure with competitive rates is a central proposal.
Standard DeductionAvailable (₹50,000).Available (₹50,000).Expected to be retained as a key relief for the salaried class.
House Rent Allowance (HRA)Exemption available under Sec 10(13A).Not Available.Unlikely to be available, aligning with the principle of removing exemptions.
Leave Travel Allowance (LTA)Exemption available under Sec 10(5).Not Available.Unlikely to be reintroduced.
Chapter VI-A DeductionsFully available (e.g., 80C, 80D, 80E, 80G, 80TTA/TTB).Largely Not Available.The core philosophy is to eliminate most of these deductions.
Allowed DeductionsAll specified deductions.Only a few are allowed, notably employer's NPS contribution u/s 80CCD(2) and deduction u/s 80JJAA.A minimal list of deductions is expected to be carried forward.
Interest on Housing Loan (Self-Occupied)Deduction up to ₹2,00,000 u/s 24(b).Not Available.Unlikely to be available for self-occupied property.
Tax Rebate u/s 87AFor income up to ₹5 lakh (Rebate of ₹12,500).For income up to ₹7 lakh (Rebate of ₹25,000).Likely to be maintained or enhanced to provide relief to lower-income groups.
Default StatusMust be explicitly chosen.Automatic default regime.The simplified regime is expected to be the sole or default system.

3. Practical Implications & Examples

The choice between the regimes has significant financial consequences. The breakeven point depends entirely on the quantum of deductions an individual can claim.

Example 1: Salaried Individual with High Deductions

  • Gross Salary: ₹15,00,000

  • HRA Exemption: ₹1,20,000

  • LTA: ₹30,000

  • Standard Deduction: ₹50,000

  • Section 80C: ₹1,50,000

  • Section 80D (Medical): ₹25,000

  • Professional Tax: ₹2,400

  • Calculation under Old Regime:

    • Taxable Income: ₹15,00,000 - (1,20,000 + 50,000 + 1,50,000 + 25,000 + 2,400) = ₹11,52,600
    • Tax Liability (approx.): ₹1,58,350 + 4% cess = ₹1,64,684
  • Calculation under New (Default) Regime:

    • Only Standard Deduction is allowed.
    • Taxable Income: ₹15,00,000 - ₹50,000 = ₹14,50,000
    • Tax Liability (approx.): ₹1,35,000 + 4% cess = ₹1,40,400

In this scenario, the New Default Regime is more beneficial despite high deductions, showcasing the impact of the lower slab rates.

Example 2: Salaried Individual with Lower Deductions

  • Gross Salary: ₹10,00,000

  • Standard Deduction: ₹50,000

  • Section 80C: ₹50,000

  • Calculation under Old Regime:

    • Taxable Income: ₹10,00,000 - (50,000 + 50,000) = ₹9,00,000
    • Tax Liability (approx.): ₹92,500 + 4% cess = ₹96,200
  • Calculation under New (Default) Regime:

    • Taxable Income: ₹10,00,000 - ₹50,000 = ₹9,50,000
    • Tax Liability (approx.): ₹50,000 + 4% cess = ₹52,000

Here, the New Default Regime provides substantial savings.

4. Compliance & Transition Checklist

Our team advises a structured approach to navigate this transition:

  • ✓ Annual Regime Comparison: For individuals without business income, conduct a comparative tax calculation under both regimes at the start of each financial year. Do not assume the choice from the previous year holds good.
  • ✓ Intimation to Employer: Inform your employer of your chosen tax regime at the beginning of the financial year to ensure correct Tax Deducted at Source (TDS). Note that this intimation is for TDS purposes only; the final choice can be made when filing the ITR.
  • ✓ Review Investment Strategy: Re-evaluate your investment strategy. Investments made purely for tax-saving purposes (like certain instruments under 80C) may lose their appeal if you consistently opt for the new regime.
  • ✓ Documentation for Old Regime: If you choose to opt out of the default regime, ensure you maintain meticulous records and proofs for all claimed exemptions and deductions (e.g., rent receipts for HRA, investment proofs for 80C).
  • ✓ Filing the Correct ITR Form: Ensure you exercise the option correctly in the Income Tax Return form. For taxpayers with business income wanting to opt-out of the new regime, filing Form 10-IEA is mandatory on or before the due date of the ITR.
  • ✓ Understand Switching Rules: Be aware of the restrictions on switching between regimes. While salaried individuals can switch annually, those with business income who opt out of the new regime can only switch back to it once in their lifetime.

5. Final Advisory

The shift to a default tax regime with minimal exemptions is a definitive policy direction, likely to be cemented and expanded under the Direct Tax Code 2025. Taxpayers and consultants must adapt to a new paradigm where financial planning is driven less by tax deductions and more by the direct benefit of lower tax rates.

This guide recommends a proactive, analytical approach each year. The "better" regime is not a one-time decision but a dynamic choice based on annual income, potential deductions, and financial goals. For high-income individuals with substantial investment-linked deductions, the old regime might still be advantageous. However, for a vast majority of middle-income taxpayers, the simplicity and lower rates of the new default regime will likely prove more beneficial. Preparing for the Direct Tax Code 2025 means mastering the intricacies of the current Section 115BAC regime today.
