Tax planning in India involves using legitimate deductions, exemptions, rebates and tax-efficient investment options available under the Income-tax Act. The right approach depends on your income, investments, expenses and whether you opt for the old or new tax regime.
This article explains the structural differences between the default New Tax Regime and the traditional Old Tax Regime, highlights statutory deduction caps under Sections 80C, 80D, 80CCD, and 24(b), and offers a practical framework for evaluating your tax liabilities.
Note: The Income-tax Act, 2025 replaced the Income-tax Act, 1961 from 1 April 2026, so sections are renumbered for FY 2026-27 onwards (for example, 80C is now Section 123, 80D is Section 126, 87A is Section 156 and 115BAC is Section 202). The section numbers used in this article are the 1961 Act numbers, which still apply to FY 2025-26 and earlier. The deduction limits discussed below are unchanged, except that the 50% HRA rate now covers eight metro cities.
Key Takeaways
-
The New Tax Regime under Section 115BAC is the statutory default. Taxpayers must opt out to claim traditional deductions under the Old Regime.
-
Salaried employees paying tax under the New Regime incur zero tax liability on salary up to ₹12.75 lakh, factoring in the ₹75,000 standard deduction and the Section 87A rebate on taxable income up to ₹12 lakh.
-
For mid-to-high income earners, the Old Regime proves beneficial only if total eligible deductions (such as HRA, 80C, 80D, and home loan interest) are very large: roughly ₹5.4 lakh at a ₹15 lakh salary, ₹7.1 lakh at ₹20 lakh, and about ₹8 lakh at ₹25 lakh and above.
-
Employer contributions to your National Pension System (NPS) account are deductible under both regimes: up to 14% of Basic plus Dearness Allowance under the New Regime for all employees, and under the Old Regime up to 10% for private-sector employees (14% for Central and State Government employees).
-
Salaried employees can choose their preferred regime annually, whereas individuals with business or professional income who opt out of the New Regime can return to it only once and cannot opt out again while their business income continues.

The Breakeven Formula
To decide between regimes, calculate your aggregate eligible exemptions and deductions:
-
If your total deductions (excluding the standard deduction) exceed the breakeven for your salary, the Old Tax Regime yields a lower tax liability. For a salaried taxpayer with no other income, the breakeven is roughly ₹5.4 lakh at a ₹15 lakh salary, ₹7.1 lakh at ₹20 lakh, and about ₹8 lakh at ₹25 lakh and above. Up to a ₹12.75 lakh salary, the New Regime means zero tax, so the Old Regime cannot beat it.
-
If your deductions are below this threshold, the New Tax Regime offers lower headline slab rates and simpler compliance, with no investment lock-ins.

Section 80C Basket (₹1.5 Lakh Ceiling)
Section 80C is the most common deduction basket, but it has a single aggregate limit of ₹1.5 lakh across all eligible items:
-
Statutory Deductions: Mandatory Employee Provident Fund (EPF) deducted by your employer automatically counts toward this limit.
-
Market-Linked Options: Equity Linked Savings Schemes (ELSS) carry the shortest lock-in period (3 years) among 80C options and offer equity market compounding.
-
Guaranteed Return Options: Public Provident Fund (PPF) and Sukanya Samriddhi Yojana (SSY) provide sovereign-backed, tax-exempt returns under the Exempt-Exempt-Exempt (EEE) structure.
Section 80D Health Insurance Deduction
Section 80D provides tax relief while securing healthcare coverage:
-
Self, Spouse, and Dependent Children: Up to ₹25,000 per financial year (including up to ₹5,000 for preventive health check-ups).
-
Parents: An additional ₹25,000 if parents are under 60 years of age, or up to ₹50,000 if parents are senior citizens. A non-senior taxpayer insuring senior parents can claim a total deduction of up to ₹75,000.
National Pension System (NPS) Deductions
-
Self-Contribution (Section 80CCD(1B)): An exclusive deduction of up to ₹50,000, bringing total deduction potential under the Old Regime to ₹2,00,000 (Section 80C + Section 80CCD(1B)).
-
Employer Contribution (Section 80CCD(2)): Under the New Regime, up to 14% of Basic Salary plus Dearness Allowance is deductible for all employees. Under the Old Regime the limit is 14% for Central and State Government employees and 10% for others. Crucially, this deduction remains available under both regimes.
Home Loan Tax Structuring: Section 24(b) vs Section 80C
Homeowners repaying a residential mortgage can divide the equated monthly instalment (EMI) into two tax deductions under the Old Regime:
-
Interest Repayment: Deductible under Section 24(b) up to ₹2,00,000 per financial year for a self-occupied property. For let-out properties, you can deduct actual interest paid, subject to loss set-off limitations of ₹2 lakh against other income heads.
-
Principal Repayment: Deductible under Section 80C up to the composite ₹1.5 lakh limit, alongside stamp duty and registration charges incurred in the year of purchase.

Tax Planning Calendar
-
April to May (Q1): Declare your intended tax regime (New vs Old) to your employer's payroll team to optimise Monthly Tax Deducted at Source (TDS).
-
June to September (Q2): If you have chosen the Old Regime, set up automated monthly SIPs in tax-saving options (such as ELSS or your own NPS contributions) to avoid lump sum liquidity pressure in March.
-
October to December (Q3): Collate documentation for home loan interest certificates, tuition fee receipts, and health insurance premium statements.
-
January to February (Q4): Submit verified investment proofs to your employer to prevent excessive TDS deductions from your final salary cycles.
Conclusion
Effective tax management is an ongoing financial habit, not a March emergency. The first step is running an objective mathematical comparison between the simplified, lower-rate New Tax Regime and the deduction-heavy Old Tax Regime. Taxpayers with large combined deductions, such as high rent (HRA), home loan interest, and 80C, 80D and NPS contributions, may still come out ahead under the Old Regime, but only if those deductions exceed the breakeven for their salary.
Those with fewer deductible expenses benefit from the New Regime's higher rebate limits and expanded standard deduction. By matching your statutory tax deductions to disciplined, goal-based investments, you protect your current cash flows while compounding long-term wealth.
