Senior citizens (aged 60 or more) are affected by the switch to the Income-tax Act 2025 in three ways: the deductions they use most are renumbered, the new tax regime removes most of them, and the paperwork for TDS changes (Form 121 replaces Forms 15G and 15H). This guide maps each deduction and benefit to its new section, states the current limits, and works through two examples that compare the old and the new regime.

Complete Deduction Map — Senior Citizens Under Old vs New Act

Deduction or benefit	Old Section	New Section	Limit	In the new tax regime?
Interest on savings, fixed and post-office deposits	80TTB	153	₹50,000 a year for a senior citizen (₹10,000 under old 80TTA for others)	No
Health insurance premium and medical expenditure	80D	126	₹50,000 for a senior citizen (₹25,000 for others); includes preventive health check-up up to ₹5,000 and, for a senior citizen with no health insurance, medical expenditure within the limit	No
Treatment of specified diseases	80DDB	128	₹1,00,000 for a senior citizen (₹40,000 for others); specialist's prescription as required by Rule 62	No
Interest on higher-education loan	80E	129	Full interest, for up to 8 years	No
Standard deduction on pension	16(ia)	19	₹50,000 (old regime); ₹75,000 (new regime)	Yes — ₹75,000
Family pension	57(iia)	93(1)(d)	One-third of the pension or ₹15,000, whichever is less; ₹25,000 where tax is computed under Section 202(1)	Yes — ₹25,000
Rebate against tax	87A	156	₹12,500 if income is up to ₹5 lakh (old regime); up to ₹60,000 if income is up to ₹12 lakh (new regime)	Yes

⚠️

Interest on deposits is not deductible in the new regime: Section 202(2) bars deductions under Chapter VIII in the new regime, apart from the exceptions in Sections 124(1), 124(2), 125(2) and 146. That covers Section 153 (old 80TTB), Section 126 (80D), Section 128 (80DDB) and Section 129 (80E). What a senior citizen keeps in the new regime is the ₹75,000 standard deduction on pension, the family-pension deduction of ₹25,000 and the Section 156 rebate.

Old Regime vs New Regime — Senior Citizen Decision Framework

The choice depends on how much of the income is pension, how much is interest, and how large the old-regime deductions are. The rates below are unchanged for Tax Year 2026-27:

New regime (Section 202(1)): nil up to ₹4 lakh, 5% on ₹4–8 lakh, 10% on ₹8–12 lakh, 15% on ₹12–16 lakh, 20% on ₹16–20 lakh, 25% on ₹20–24 lakh, 30% above ₹24 lakh; rebate under Section 156 makes tax nil up to ₹12 lakh, with marginal relief just above it.
Old regime, age 60 to 79: nil up to ₹3 lakh, 5% on ₹3–5 lakh, 20% on ₹5–10 lakh, 30% above ₹10 lakh; nil up to ₹5 lakh for age 80 and above; rebate of up to ₹12,500 if total income is up to ₹5 lakh.

Hypothetical figures — Tax Year 2026-27, health insurance premium paid by each

	Case A — pension ₹4.8 lakh	Case B — pension ₹9 lakh
Bank FD interest	₹1,20,000	₹4,00,000
Other income (Case A: bond interest ₹18,000 + dividend ₹22,000; Case B: dividend ₹50,000)	₹40,000	₹50,000
Gross income	₹6,40,000	₹13,50,000
Old regime: less standard deduction ₹50,000, Section 153 ₹50,000, Section 126 (₹42,000 premium in A, ₹50,000 in B)	Total income ₹4,98,000	Total income ₹12,00,000
Old regime tax after rebate, with 4% cess	Nil (tax ₹9,900, rebate ₹9,900)	₹1,76,800
New regime: less standard deduction ₹75,000	Total income ₹5,65,000	Total income ₹12,75,000
New regime tax after rebate, with 4% cess	Nil (tax ₹8,250, rebate ₹8,250)	₹74,100

In Case A both regimes give nil tax — the old regime only because the deductions bring total income just under ₹5 lakh, the new regime because of the ₹12 lakh rebate. In Case B the old regime's deductions of about ₹1.5 lakh do not offset the new regime's lower slabs, and the new regime saves about ₹1.03 lakh.

Lesson: run both computations every year. Interest income and premiums decide the old regime's value, but the new regime is often lower once income passes the ₹5 lakh level.

Senior Citizen Benefits Specific to Tax Administration

No advance tax: a resident individual aged 60 or more at any time during the tax year, with no income from business or profession, is not liable to pay advance tax (Section 403(3), old Section 207). Pay the balance as self-assessment tax before filing. Interest for a late return (old Section 234A, now Section 423) can still apply; the advance-tax interest provisions do not apply to a person who is not liable for advance tax.
TDS on interest: banks and post offices deduct TDS on a senior citizen's interest only when it exceeds ₹1,00,000 a year from one payer (₹50,000 for others) — the thresholds in force since 1 April 2025.
Stopping TDS: a senior citizen whose total income is below the taxable limit gives the payer a declaration in Form 121 (which replaces Forms 15G and 15H).
Age 75 and above: old Section 194P — a resident aged 75 or more with only pension and interest income from the same bank can give the bank a declaration (Form 125, earlier Form 12BBA); the bank then computes tax after Chapter VIII deductions and the Section 156 rebate (Rule 208; Section 393(1), Table Sl. No. 8(iii)). Confirm the clause of the return provisions that relieves such a person from filing a return before citing it.
Return due date: for FY 2025-26 (AY 2026-27), 31 July 2026 for ITR-1 and ITR-2 filers with no business income.

Senior Citizen Tax Planning Checklist

Compare the old and new regime every year — interest income and health premiums drive the answer
Give banks a Form 121 at the start of the year if your total income will be below the taxable limit
Age 75 or more: check whether the single-bank declaration (Form 125) suits you
Old regime only: claim Section 153 (₹50,000 interest), Section 126 (₹50,000 health insurance), Section 128 and Section 129 where they apply
For a specified disease, get the specialist's prescription in the format required by Rule 62 before claiming Section 128 (₹1 lakh)
Keep premium receipts, interest certificates and bank statements ready for the return

Frequently Asked Questions

Yes, if they qualify. Section 403(3) says the advance-tax liability in Section 403(1) does not apply to a resident individual who has no income from business or profession and is aged 60 or more at any time during the tax year. Such a person pays the tax as self-assessment tax when filing. Interest for delay in filing the return can still apply, but the advance-tax interest provisions do not apply to someone who is not liable for advance tax.

Pension from a former employer is salary income and qualifies for the standard deduction in Section 19 of the Income-tax Act 2025. It is ₹75,000 in the new tax regime and ₹50,000 in the old regime. The amount does not depend on age — it applies to all pensioners and salaried taxpayers.

No. Section 153 (which combines old Sections 80TTA and 80TTB) is a Chapter VIII deduction, and Section 202(2) bars Chapter VIII deductions in the new regime except those in Sections 124(1), 124(2), 125(2) and 146. A senior citizen can claim up to ₹50,000 of deposit interest under Section 153 only if they choose the old regime.
