Every February and March, the same ritual plays out in offices across India. Someone in HR sends a reminder about investment proofs, and suddenly everyone is scrambling to show ₹1.5 lakh under Section 80C — PPF, ELSS, EPF, life insurance premium, a five-year FD. Then, once the 80C limit is filled, most people stop. They assume there is nothing more to save.
That assumption costs real money. Section 80C is only one deduction among many, and for a salaried person earning, say, ₹15 lakh a year, the deductions beyond 80C can easily save another ₹20,000 to ₹40,000 in tax every year. The rules are not complicated. They are just scattered across different sections of the Income Tax Act, and nobody puts them together in one place — which is exactly what this guide does.
One thing to note before we start: these deductions apply under the old tax regime. If you have chosen the new regime, most of them are not available, because the new regime trades lower slab rates for fewer deductions. So the first decision is always the regime itself — and for many people with a home loan, health insurance, and NPS contributions, the old regime still wins. Work that comparison out first; everything below assumes you are in the old regime.
Section 80D: health insurance, the deduction people underuse
Section 80D covers health insurance premiums, and it is the single most underused deduction after 80C. You can claim up to ₹25,000 a year for health insurance premiums paid for yourself, your spouse, and your children. If you also pay premiums for your parents, you get another ₹25,000 for them. And if either you or your parents are senior citizens, the limits rise: ₹50,000 for yourself and family if you are a senior citizen, and ₹50,000 for senior-citizen parents.
So a person in their late thirties who pays ₹18,000 a year for a family floater policy and ₹32,000 a year for their parents’ policy can claim ₹50,000 in total — ₹18,000 for the family plus ₹32,000 for the parents, capped at ₹25,000 and ₹25,000 respectively, which comes to ₹50,000. In the 30% slab, that is ₹15,000 of tax saved, and the insurance itself is protection the family needs anyway.
There are two details that trip people up. First, the premium must be paid by a mode other than cash — online payment, cheque, or card. Cash premiums do not qualify. Second, preventive health check-ups of up to ₹5,000 a year are also covered within the same overall 80D limit, so the cost of an annual full-body check-up for the family can count too.
If your parents are senior citizens and you buy them a policy costing ₹45,000, the whole ₹45,000 is deductible within the ₹50,000 senior-citizen limit. If they have no insurance at all and you pay their medical bills instead, medical expenditure on senior citizen parents is also deductible up to ₹50,000 under the same section — a rule that helps families whose parents are too old or unwell to get a policy.
Section 80CCD(1B): the extra ₹50,000 for NPS
This is the easiest extra deduction in the whole tax code, and one of the least claimed. On top of the ₹1.5 lakh under 80C, you can claim an additional ₹50,000 a year for contributions to the National Pension System under Section 80CCD(1B). It sits outside 80C entirely, so it is genuinely extra.
The maths is straightforward. Contribute ₹50,000 to your NPS Tier I account in a year, claim the full ₹50,000 as a deduction, and if you are in the 30% slab you save ₹15,000 in tax — a 30% return on the contribution before the NPS itself earns anything. Even in the 20% slab, that is ₹10,000 saved. There are very few places where the government hands you that kind of immediate return for saving for your own retirement.
NPS has its own quirks — the money is locked in until retirement, with only partial withdrawals allowed, and at maturity you must use at least 40% of the corpus to buy an annuity. Those are real constraints. But as a tax-saving tool for money you were going to keep for retirement anyway, the extra ₹50,000 deduction is hard to beat. And your employer’s contribution to NPS, up to 10% of your basic salary, is deductible under a separate provision, 80CCD(2), on top of everything else. If your employer offers NPS as part of your salary structure, take it — it reduces your taxable income without costing you anything extra.
HRA: the deduction renters forget to claim properly
House Rent Allowance is one of the largest deductions available to salaried people, and one of the most badly claimed. If you live in rented accommodation and your salary includes HRA, the exempt portion is the lowest of three numbers: the actual HRA you receive, the actual rent you pay minus 10% of your basic salary plus dearness allowance, and 50% of your basic salary if you live in Mumbai, Delhi, Chennai or Kolkata, or 40% in other cities.
Take a concrete example. Your basic salary is ₹50,000 a month, so ₹6,00,000 a year, and your HRA is ₹20,000 a month, or ₹2,40,000 a year. You pay ₹18,000 a month in rent in Pune, which is ₹2,16,000 a year. The three numbers are: actual HRA ₹2,40,000; rent minus 10% of basic, which is ₹2,16,000 minus ₹60,000, or ₹1,56,000; and 40% of basic, which is ₹2,40,000. The lowest is ₹1,56,000, so that is your exemption. In the 30% slab, that is ₹46,800 of tax saved on rent you were paying anyway.
Two things people get wrong here. First, you need rent receipts, and if the rent is more than ₹1 lakh a year, you need the landlord’s PAN — get it when you sign the rent agreement, not in March. Second, if you pay rent but your salary has no HRA component at all, you can still claim up to ₹60,000 a year under Section 80GG, provided you do not own a house in the city where you live and work. Many people in startups or small companies miss this entirely.
Home loan interest: Section 24(b), the big one
If you have a home loan on a house you live in, the interest you pay — up to ₹2 lakh a year — is deductible under Section 24(b). This is separate from 80C, which covers the principal repayment up to ₹1.5 lakh. So a home loan gives you two deductions at once: principal under 80C and interest under 24(b).
On a ₹50 lakh loan at 9% over 20 years, the interest in the early years is roughly ₹4.4 lakh a year — far more than the ₹2 lakh cap, so you will use the full deduction for years. In the 30% slab, that is ₹60,000 of tax saved every year from the interest alone. This is the single biggest reason the old regime often beats the new regime for homeowners, and it is worth doing the maths before you switch regimes, because the new regime does not allow this deduction for a self-occupied house.
There is more. If you are a first-time homebuyer, Section 80EEA offers an additional deduction of up to ₹1.5 lakh a year on home loan interest, over and above the ₹2 lakh under 24(b), for loans sanctioned within the specified window and for houses within the value limit. The window has specific dates, so check whether your loan qualifies, but if it does, that is another ₹45,000 of tax saved in the 30% slab.
And if you have taken a loan for an under-construction property, the interest paid during construction — called pre-construction interest — can be claimed in five equal instalments starting from the year construction completes, along with the regular interest, subject to the same ₹2 lakh overall cap.
The smaller deductions that quietly add up
Beyond the big four, there is a list of smaller deductions that together can add several thousand rupees of savings a year.
Section 80TTA and 80TTB. Interest on your savings account is deductible up to ₹10,000 a year under 80TTA. For senior citizens, 80TTB raises this to ₹50,000 and covers interest from fixed deposits and recurring deposits too. If you are a senior citizen with ₹8 lakh in FDs earning 7%, that is ₹56,000 of interest, of which ₹50,000 is exempt — a saving of ₹15,000 in the 30% slab.
Section 80G. Donations to approved charities and relief funds are deductible, some at 100% and some at 50%, with or without a cap. Donations must be made by a mode other than cash if they are above ₹2,000. Keep the receipt and the charity’s registration details, because the tax department can ask for them.
Section 80E. Interest on an education loan — for yourself, your spouse, or your children — is fully deductible for up to eight years, with no upper limit. There is no cap at all, which makes it one of the most generous deductions in the Act. On a ₹20 lakh education loan at 10%, the first year’s interest alone is about ₹2 lakh, fully deductible.
Section 80DD and 80U. If you have a dependent with a disability, or you yourself have a disability, there are flat deductions of ₹75,000 a year, rising to ₹1,25,000 for severe disability. These are often missed entirely by families who qualify.
Section 80C’s neighbours. A few things that look like 80C but are not: your EPF contribution and your employer’s NPS contribution sit partly outside 80C, as noted above, and the interest on your PPF is tax-free. Keeping these straight is what lets you use the full ₹1.5 lakh of 80C for the things that need it most.
Putting it together: a worked example
Let us see what all of this adds up to for a realistic person. Meet Priya, 35, living in Pune, earning ₹18 lakh a year, in the 30% slab, under the old regime.
She fills her 80C with EPF, PPF and an ELSS, saving ₹46,800 in tax. Then she claims ₹50,000 under 80D for her family floater and her parents’ policy, saving ₹15,000. She puts ₹50,000 into NPS under 80CCD(1B), saving another ₹15,000. Her HRA exemption is ₹1,56,000, saving ₹46,800. Her home loan interest gives her the full ₹2 lakh under 24(b), saving ₹60,000. Her savings account interest gives her ₹10,000 under 80TTA, saving ₹3,000.
Add it up: beyond 80C, she has claimed deductions worth about ₹4.66 lakh, saving her roughly ₹1,39,800 in tax. Her total deductions, including 80C, come to over ₹6 lakh. None of this required exotic planning or a chartered accountant. It required a health insurance policy her family needed, an NPS account for retirement, a rent agreement, and a home loan she already had. The tax saving is what happens when ordinary financial decisions are documented properly.
A short checklist for this year
Tax saving beyond 80C is mostly a matter of paperwork and timing, so here is a checklist worth running through before the financial year ends.
First, check your regime. If your deductions beyond 80C add up to more than about ₹2 lakh, the old regime usually wins; if you have almost none, the new regime probably does. Do not assume — calculate it once.
Second, pay your health insurance premium online, get your parents’ policy in place if they do not have one, and keep the receipts. Claim the preventive health check-up within the same 80D limit.
Third, put the ₹50,000 into NPS before March 31 if you have not already, and ask your employer whether NPS is available in your salary structure.
Fourth, collect rent receipts through the year and get your landlord’s PAN if your rent crosses ₹1 lakh a year. If you have no HRA, check 80GG.
Fifth, keep your home loan interest certificate from the bank — it arrives every year and it is the document that supports the biggest deduction most people claim.
And finally, do all of this before March, not in March. The deductions exist all year. The people who save the most tax are not the ones with the cleverest plans; they are the ones who set the pieces in place early and let the year do the work.
