A Complete Guide to Income Tax Deductions Beyond Section 80C

Maxed out your ₹1.5 lakh limit under Section 80C — Section 123 in the new Act's numbering — and assumed that's the end of the road for tax-saving? It isn't, at least not if you're on the old regime. There's a long tail of deductions that plenty of salaried taxpayers and professionals leave unclaimed simply because they're less talked-about than PPF and ELSS. Several of them matter even if you've never itemised a deduction beyond PPF before, and a couple are worth knowing even if you've already moved to the new regime.

Health Insurance Premium: Section 80D

Section 80D lets you deduct health insurance premiums for yourself, your spouse, and your dependent children, up to ₹25,000 a year — rising to ₹50,000 if the eldest person covered is a senior citizen. Premiums paid for your parents' health cover sit in a separate bucket entirely: another ₹25,000, or ₹50,000 if either parent is a senior citizen. That means a taxpayer paying for their own family's policy and a senior-citizen parent's policy can claim up to ₹1,00,000 in total in a single year. A preventive health check-up, capped at ₹5,000, is included within these limits rather than added on top of them, so it doesn't stretch the ceiling any further. Even a modest ₹8,000-10,000 premium for a basic family floater plan is worth claiming — it's easy to forget since the payment happens once a year at renewal time, long before filing season. This deduction is old-regime only.

NPS Gives You Two Separate Deductions

The National Pension System offers two distinct tax breaks, and mixing them up is a common mistake. Section 80CCD(1B) allows an additional ₹50,000 deduction for your own contribution to a Tier I NPS account, over and above the ₹1.5 lakh ceiling under 80C — old regime only. Separately, Section 80CCD(2) covers your employer's contribution to your NPS account, deductible up to 10% of salary generally, up to 14% for government employees, and — since a change a couple of years ago — up to 14% for private-sector employees too, provided they're on the new regime. That last point matters: 80CCD(2) is one of the very few deduction-style benefits that survives under the new regime, so it's worth asking whether your employer can route part of your CTC through NPS contributions even if you've moved to the new regime for everything else.

HRA and Home Loan Interest: the Big-Ticket Deductions

For salaried employees who pay rent, HRA exemption is usually the single largest deduction available, calculated as the lowest of three figures: the actual HRA received, rent paid minus 10% of basic salary plus dearness allowance, or 50% of basic-plus-DA for a metro city (Delhi, Mumbai, Kolkata, or Chennai) versus 40% elsewhere. It's old-regime only, and applies only if you're actually paying rent and receiving an HRA component in your salary. If you're self-employed, or salaried without an HRA component, Section 80GG offers a smaller substitute — the lowest of ₹5,000 a month, 25% of total income, or rent paid minus 10% of income. Home loan interest works differently depending on how the property is used: interest on a loan for a self-occupied house is capped at ₹2,00,000 a year under Section 24(b) (dropping to ₹30,000 if construction isn't finished within five years of taking the loan), and this too is available only under the old regime. Interest on a loan for a property that's rented out, however, remains fully deductible with no upper cap even under the new regime, because it's computed as part of house-property income rather than claimed as a standalone Chapter VI-A deduction.

Smaller but Real: Education Loan and Deposit Interest

• Section 80E — education loan interest: no rupee ceiling at all on the interest claimed, for a loan taken for the higher education (in India or abroad) of yourself, your spouse, your children, or a student for whom you're the legal guardian. The deduction runs for 8 consecutive years starting from the year repayment begins, or until the interest is fully repaid, whichever comes first. Only interest qualifies, not principal. Old regime only.
• Section 80TTA — savings account interest: up to ₹10,000 a year for taxpayers below 60, on interest from savings accounts only, not fixed deposits. Old regime only.
• Section 80TTB — deposit interest for senior citizens: a more generous ₹50,000, covering interest from savings accounts, fixed deposits, and recurring deposits alike. Senior citizens use this instead of 80TTA, not in addition to it.
• A common mistake either way: this interest isn't tax-exempt, it's deductible up to the limit — anything earned above ₹10,000 (or ₹50,000 for seniors) is fully taxable and needs to be reported.

The pattern across almost all of these is the same: they belong to the old regime, with employer NPS contributions and let-out-property home loan interest as the lone exceptions. That's worth remembering before you assume switching to the new regime is automatically simpler — if your list here runs long (health cover for parents, an education loan, a home loan, and NPS all at once), the old regime may still work out cheaper even after accounting for its higher slab rates. If your list is short, the new regime's lower rates are probably doing you more good than these deductions ever would. Either way, the only way to know for certain is to add up what you can genuinely support with proof — premium receipts, loan interest certificates, rent receipts — and compare, rather than assuming.
