Guide to Key Income Tax Deductions
1. Sec 123 & 124(3) (formerly 80C & 80CCD(1B))
These sections provide the core tax-saving mechanism under the Old Regime. They reward long-term savings and necessary expenses:
- Section 123 (old 80C): Deducts up to ₹1.5 Lakh for investments (PPF, ELSS, NSC, Life Insurance, home loan principal).
- Section 124(3) (old 80CCD(1B)): Allows an additional ₹50,000 for contributions made to the National Pension System (NPS Tier-I account). This benefit is separate from the ₹1.5 Lakh limit.
2. HRA Exemption (Section 10(13A))
Available exclusively under the Old Regime, HRA exemption reduces taxable income for salaried individuals living in rented housing. The exempt amount is the minimum of three conditions:
- Actual HRA received from the employer.
- Actual rent paid minus 10% of Basic Salary + DA.
- 50% of Basic Salary + DA (Metro Cities: Delhi, Mumbai, Kolkata, Chennai) or 40% (Non-Metro).

- Standard Deduction: ₹75,000 flat deduction from salary or pension.

- Sec 80CCH: Contribution to the Agniveer Corpus Fund.
Frequently Asked Questions
What are the key differences between the Old and New Tax Regimes (Section 202 under ITA 2025)?
The New Regime (Sec 202, formerly 115BAC) is the default under the new Income Tax Act 2025. For Tax Year 2025-26, it offers lower slab rates, a higher basic exemption limit of ₹4 lakh, and makes income up to ₹12.75 lakh tax-free (including standard deduction). However, you must forego common deductions like Sec 123 (old 80C) and HRA. The Old Regime uses higher slab rates but allows you to claim all your deductions and exemptions.
What deductions are allowed under the New Regime for Tax Year 2025-26?
While most deductions are disallowed, you can claim the Standard Deduction of ₹75,000 against your salary/pension. You can also claim deductions for Employer's contribution to NPS under Section 124 (formerly 80CCD(2)) and Agniveer Corpus Fund under Section 80CCH.
What is the ITR filing deadline for FY 2025-26?
The ITR filing deadline for non-audit cases for FY 2025-26 (AY 2026-27) is July 31, 2026. Late filing incurs a ₹5,000 penalty (or ₹1,000 if income is below ₹5 lakh) under Section 234F.
Can I switch between old and new tax regimes?
Salaried individuals can switch between regimes every year when filing ITR. Business/professional taxpayers are restricted: if they opt out of the new regime once, they can only switch back once in a lifetime (unless they cease having business income).
