Tax Deduction Mapping for Senior Citizens Under New Act 2025 — Complete Guide
Senior citizens (age 60+) are among the most directly impacted by the Income-tax Act 2025 transition — their key deductions are renumbered, the new tax regime has a structural exception specifically for their interest income, and some long-standing benefits (advance tax exemption, higher TDS threshold, ITR exemption for 75+) need to be understood under the new Act's language. This guide provides a complete deduction-by-deduction mapping with a practical worked example comparing old vs new regime for a retired pensioner.

Old Regime vs New Regime — Senior Citizen Decision Framework
The decision for a senior citizen between the old regime (more deductions) and new regime (lower slab rates) depends primarily on the quantum of interest income, health expenses, and pension income.
Case Study: Retired Bank Officer Ramesh — Old vs New Regime
Ramesh (67) receives: pension ₹4.8 lakh/year, FD interest ₹1.2 lakh/year from ₹20 lakh FDs, SGB interest ₹18,000/year, dividend ₹22,000/year. Health insurance premium paid: ₹42,000/year (private policy, no group policy). Medical expenses for diabetes management: ₹28,000/year (no certificate from specialist — cannot claim 80DDB).
Old regime calculation: Total income = ₹4.8L + ₹1.2L + ₹18K + ₹22K = ₹6.6 lakh. Less: standard deduction on pension ₹50,000 = ₹6.1L. Less 80TTB (FD interest) ₹50,000 = ₹5.6L. Less 80D (health insurance) ₹42,000 = ₹5.18L. Tax on ₹5.18L (old slab, senior citizen: NIL up to ₹3L, 5% on ₹2.18L) = ₹10,900. Rebate 87A: not eligible (above ₹5L). Final tax ≈ ₹10,900 + cess = ~₹11,336. New regime: ₹6.6L less standard deduction ₹75K = ₹5.85L. Tax on ₹5.85L (new slab) = ~₹21,000 + cess = ~₹21,840. Old regime saves ₹10,504 — choose old regime.
Lesson: For senior citizens with significant interest income and health insurance premiums, the old regime almost always wins. The 80TTB benefit alone is ₹50,000 — which at the 5% slab saves ₹2,500, and at the 20% slab saves ₹10,000.
Senior Citizen Benefits Specific to Tax Administration
- No advance tax: Senior citizens (60+) with no business/professional income are exempt from paying advance tax — pay all tax as self-assessment tax by July 31 (new Act: 31 August for Tax Year 2026-27)
- Higher TDS threshold on FD interest: Banks deduct TDS only when annual interest exceeds ₹50,000 (₹40,000 for non-seniors)
- Form 15H: Senior citizens can submit Form 15H (old: same name, new: merged into Form 121) to prevent TDS if total income is below taxable limit
- Simplified ITR: Senior citizens above 75 with only pension and interest income from the bank that deducts TDS are exempt from filing ITR under Section 194P (new Act: Section 391) — if enrolled with the bank
Senior Citizen Tax Planning Checklist
- Compare old vs new regime every year — interest income and health premium levels determine the better regime
- Submit Form 121 (new; old Form 15H) to banks before April 1 to prevent unnecessary TDS
- Age 75+: check 194P/391 exemption from filing — only if single bank, only pension + interest
- Claim 80TTB (₹50,000) interest deduction in old regime — also available in new regime as exception
- Claim 80D (₹50,000 limit for seniors) for health insurance premiums — old regime only
- For specified diseases (diabetes complication, cancer, kidney failure) — get Form 10I certification from specialist to claim Section 129 (old 80DDB) — ₹1 lakh deduction
- Keep health insurance receipts, FD interest certificates, and bank statements ready for ITR filing
