Tax-saving instruments, honestly

Sections and limits as at FY 2026-27. The old/new regime choice, deduction limits and section numbering all change with the Finance Act. Everything below is an educational framework with current figures stated so you can check the logic. Verify against current law and your own return. Not tax advice.

Here is the uncomfortable idea at the centre of this lesson, and it is worth stating before any table:

A tax deduction is a loan from the government at your marginal tax rate — repayable by whatever you would otherwise have spent.

If you would never have bought an ELSS fund, the ₹1.5 lakh deduction is not a saving. It is ₹1.5 lakh of forced investment, illiquid for three years, chosen so you can reduce a tax bill you were going to pay anyway. The arithmetic is exact: at a 30% slab, a full ₹1.5 lakh 80C usage is worth ₹45,000 of tax. Everything else about the product is separate.

Most people treat "tax-saving" as a product category. It is a rate of return on a decision, and it belongs after the question, not before it.

The regime question comes first

The deduction-oriented instruments below only exist inside the old regime. The new regime, the default for most individual taxpayers, gives a much higher standard deduction and removes most deductions — including the ones this article is about.

	Old regime	New regime
80C	₹1,50,000 available	Not available
80D health insurance	Available (₹25,000 / ₹50,000 senior)	Not available
HRA exemption (s.10(13A))	Available	Not available
s.24(b) home loan interest	Up to ₹2,00,000 self-occupied	Only for let-out property, no cap
80CCD(1B) NPS ₹50,000	Available	Not available
80CCD(2) employer NPS	Up to 10% of salary	Up to 14% of salary
Standard deduction	₹50,000	₹75,000
87A rebate	Up to ₹12,500 (income to ₹5 lakh)	₹60,000 (income to ₹12 lakh)
Marginal rate relief	Applies	Applies

The pattern is worth internalising: under the new regime essentially every Chapter VI-A deduction is switched off, and the only ones that survive are employer NPS under 80CCD(2), the Agniveer corpus deduction under 80CCH, and the additional employee cost deduction under 80JJAA. If you own a term insurance premium, pay health cover, or claim HRA, you are very likely in the old regime — that comparison is not a detail, it is the whole decision.

The practical sequence:

1. Compute your tax under both regimes with real numbers.
2. Pick the lower one. Most people should do this comparison annually — the answer flips as income rises.
3. Only then decide how to use any remaining deductions.

Doing this the other way round — picking an ELSS and then discovering the new regime is cheaper — is how people end up holding products they did not want for tax reasons that evaporated.

Section 80C — ₹1.5 lakh, and a list of very different things

Option	Lock-in	What it actually is
ELSS mutual fund (equity)	3 years	Market risk + LTCG tax treatment
PPF	15 years, extends in 5-year blocks	Guaranteed, tax-free, government-backed
EPF	Until you exit the scheme	Retirement benefit, tax-free
Sukanya Samriddhi	21 years from opening	Girl child; 8.2%, tax-free, EEE
Senior Citizen Savings Scheme	5 years, then quarterly payout	Tax-free, 7–8%
National Savings Certificate	5 years	7.7%, fully taxable at maturity
Life insurance premium	Term premium	Pure protection — no savings at all
Principal on a home loan	Until the loan closes	Not a saving; you are repaying debt
Rent (HRA exemption)	None	Money you were spending anyway
80C(a)/(b)/others	Various	Small-savings, postal schemes

The list looks uniform. It is not. A term insurance premium under 80C is a genuine expense that protects a family; an ELSS is a market bet; PPF is a 15-year commitment. Treating them as interchangeable is the category error that costs the most money.

The 80C deadline trap

The section is usable for the whole assessment year, and the previous year's returns can be filed late to claim the earlier year in a revised return — but this is now time-limited and condition-bound, and revised returns carry a cost and are not a reliable strategy. The genuine deadline is:

31 March of the financial year. Not 15 April. Not "I will do it next month."

Money invested on 1 April belongs to the next year. This is the single most common and most expensive tax mistake, and it is a calendar problem, not a finance problem.

Section 80D — health cover, and the two things people miss

	Self and family	Senior citizens
Section 80D	Up to ₹25,000	Up to ₹50,000
Preventive health check-up	Additional, within the limit	Additional, within the limit
Section 80DD (severe disabilities)	Higher limits	Higher limits

Two features that are frequently missed:

1. The 5-year rule. A top-up health policy bought to keep a floater family together is not eligible for 80D. Only the first ₹25,000 of the base cover counts. This is genuinely good news for most households: you should buy enough cover, not just enough to fit the deduction.

2. Senior-citizen benefit. Above 60, the limit rises to ₹50,000, and the rules are more generous.

The deduction is nice. It is not a reason to under-insure. The medical bill that motivates a ₹5 lakh top-up will not care about your remaining deduction.

Section 80CCD(1B) — the extra ₹50,000

An additional ₹50,000 deduction on NPS contributions, over and above the 80C limit, for salaried individuals with taxable income. It is an old-regime-only deduction — under the new regime this ₹50,000 simply is not available, and one of the most common "I use the new regime" mistakes is leaving it on the list anyway.

The arithmetic that makes it interesting:

₹50,000 × 30%  +  4% cess  =  ₹15,600 of tax saved

And against that, the cost. NPS Tier-I investments are locked until age 60, with only a limited 25% pre-retirement withdrawal at 15-year contributions and 50% at 10 years. An early exit is possible in defined exceptional cases only.

So you would be tying up ₹50,000 for potentially three decades to save roughly ₹15,600 of tax. For a young salaried person that can be worth it, because the long compounding period may outweigh the tax. For someone about to retire, the lock-in makes it poor value. The same deduction is good for a 28-year-old and bad for a 56-year-old, and the reason is the horizon, not the tax.

Section 24(b) — home loan interest

Deduction on interest paid on borrowing to acquire or construct a residential property. It is one of the few items that behaves completely differently across the two regimes:

• Old regime: up to ₹2,00,000 per year for a self-occupied property.
• New regime: the self-occupied cap is gone entirely — but the deduction is still available without limit on a let-out (rented-out) property, because it is then treated as a business expense against that rental income.

So a self-occupied borrower is heavily penalised by the new regime, while a landlord with a let-out property is not. That asymmetry surprises almost everyone, and it means the regime choice is not one decision for a household — it can be two different answers for two people in the same flat.

A vehicle loan gets nothing. s.24(b) is specific to residential property; car, personal and gold loans get no deduction whatsoever.

The part that surprises people: this is a deduction for a debt you are paying anyway. The home loan principal is not tax-free, and the loan itself is a negative-return instrument. See Debt and loans: when to pre-pay.

This is a real deduction, and on a ₹40 lakh loan at 8.5% the interest portion in year one is about ₹3.4 lakh, so a household in a high bracket can save meaningfully. But the deduction is an argument for the loan you already have, not an argument to take a new one.

Section 80CCD(2) — the one that needs no investment

An employer's NPS contribution is deductible for the employee, with no 80C limit and no minimum tenure. You do nothing, and you get the deduction.

The ceiling depends on the regime you are in: up to 10% of basic salary plus dearness allowance under the old regime, and up to 14% under the new regime — a genuine new-regime advantage, and one of the few. If your employer contributes more than 10% of your salary and you are on the new regime, that difference is being wasted.

Most employees never claim it. It costs nothing to claim, needs no lock-in, and is frequently worth tens of thousands of rupees. If you are salaried and you have not claimed it, this is the highest-return five minutes available in this article.

Also worth checking, because it is money left on the table:

• 80TTB / 80TTA — deduction on interest earned on your savings account, and on the interest component of a senior citizen's FD income. Small, automatic, and often unclaimed.
• HRA exemption — if you are renting and your employer is not paying a rent-equalised component, this is often worth lakhs. Almost entirely unclaimed by people who own or live with family.
• Standard deduction — now available under the new regime too, and relevant to the regime comparison in step 1.
• Section 87A rebate — a rebate of up to ₹60,000 on tax for a resident individual with total income up to ₹12 lakh under the new regime, and up to ₹12,500 on income up to ₹5 lakh under the old regime. It is why small taxpayers pay near zero. One important trap: income taxed at special rates is excluded when computing the 87A threshold, so a large LTCG or dividend income can leave you owing tax even when your "total income" looks comfortably under the limit.

Worked example — is 80C worth it?

A 35-year-old, single, no home loan, no dependents, ₹18 lakh total income, old regime chosen.

Using the old-regime slabs (₹2.5L nil, ₹2.5–5L at 5%, ₹5–10L at 20%, above ₹10L at 30%), plus 4% cess:

Without 80C or 80CCD(1B):
  Taxable income                ₹18,00,000
  Tax                           ₹ 3,52,500
  + 4% health & education cess    ₹  14,100
                                ───────────
  Total tax                      ₹ 3,66,600

With ₹1,50,000 of 80C + ₹50,000 of 80CCD(1B):
  Taxable income                ₹16,00,000
  Tax                           ₹ 2,92,500
  + 4% health & education cess    ₹  11,700
                                ───────────
  Total tax                      ₹ 3,04,200
                                ───────────
  Tax saved                      ₹   62,400

So the maximum 80C plus 80CCD(1B) is worth about ₹62,400 of tax on an ₹18 lakh income — not the ₹2,00,000 many people assume. Both the full 80C limit and the extra 80CCD(1B) sit entirely in the 30% band, so the ceiling on the value of a rupee of deduction is 30% plus 4% cess, and every extra rupee of deduction beyond that band is worth less than the one before it.

Now the real question. What does that ₹2,00,000 of locked capital have to do for the saving to be worthwhile?

• If the ₹50,000 80CCD(1B) portion goes into a 15-year PPF at ~7.1% with zero tax, it grows to roughly ₹1.4 lakh by the time the person is 50. That comfortably outweighs the ₹15,600 of tax that the same ₹50,000 saved.
• If it goes into a 3-year ELSS and then is redeemed for a tuition bill: the tax saved may exceed the market risk taken.

But if the person has no dependents, no home loan, and no HRA, the honest answer is that most of the ₹1.5 lakh of 80C has nothing to buy — and the better use is a larger emergency fund and more equity exposure. For that person, a partial 80C plus the rest invested properly beats a full 80C chosen to fill a limit.

The saving is the reward, not the reason. An investor who uses 80C because it is mandatory and ELSS because it is the only option is fine. An investor who uses 80C because it is wrong is worse off, because the lock-in continues regardless of the regime they end up choosing.

Where the returns are actually weak

A broad group of small-savings products — NSC, Postal Office MIS, Senior Citizen Monthly Income Scheme, some bank FD variants — is often marketed as "tax-free, guaranteed 7–8%". The compounding works, but the tax treatment of the interest and the post-maturity withdrawal treatment can be worse than the headline suggests.

Read the tax clause, not the rate card. The rate is the marketing. The tax treatment is the contract. See Where to park cash for the full comparison.

Failure modes

Buying an ELSS to use the deduction, then holding it out of fear. The 3-year lock-in has already happened. The additional penalty for holding a good equity fund is emotional, and it is self-inflicted.

Claiming 80C on a top-up health policy. Not eligible after the first 5 years. The 80D limit is ₹25,000, not the policy sum insured — do not confuse a deduction with coverage.

Chasing 80CCD(1B) at 55. A 5-year lock-in with a 60-year horizon is worse than a 5-year lock-in at 25. The tax saving is identical; the compounding opportunity is not.

Missing 80CCD(2) and 80TTB. Money on the table, no downside, no lock-in, no product to buy.

Claiming a deduction and never having income tax to set off against. Not an issue for most salaried people, but a genuine trap for someone whose total income is below the rebate threshold.

Treating HRA as a formality. It is often worth more than 80C, and it is the most under-claimed deduction in India.

Surrendering a policy to show the deduction. You already paid the premium and you are now realising a loss. The deduction is not a reason to destroy an asset.

Buying a product to fill a limit in a financial year you should have switched regimes. Recompute the regime comparison every year.

Exercise

1. Compute your tax under both regimes. Which is lower, and by how much?
2. List every deduction you are eligible for but not claiming: 80C, 80D, 80CCD(1B), 80CCD(2), HRA, 80TTB, 87A.
3. For each unused deduction, write what it buys — which specific instrument, with what lock-in, at what expected return.
4. For each, compute: tax saved ÷ capital locked ÷ years of lock-in. Call it tax efficiency per year.
5. Does the tax saved exceed the return you gave up by not putting that money in your best risk-appropriate investment?
6. How much of your 80C is spent anyway (rent, loan principal, term insurance) versus genuinely new money?
7. If you had to redeem any of it in an emergency, what happens to the deduction?

Step 7 is the one that separates a real plan from a tax-shaped one.

Checklist

1. Have I compared the old and new regimes with real numbers this year?
2. Do I know my 80C usage as a percentage of the ₹1,50,000 limit?
3. Have I invested before 31 March, not after?
4. Am I counting a top-up health policy in 80D? It does not count after 5 years.
5. Have I claimed 80CCD(2) from my employer?
6. Do I have a preventive health check-up in the 80D claim?
7. Am I eligible for HRA and claiming it?
8. Have I considered 80CCD(1B) as a horizon decision, not a free ₹50,000?
9. For any "tax-free guaranteed" product, have I read the actual tax clause?
10. Is any deduction pushing me toward a product I would not otherwise buy?
