You have put Rs. 1.5 lakh into ELSS, EPF, and LIC. Section 80C is full. Most people stop there and pay the rest in taxes, not knowing there are seven more buckets available under the old tax regime.

Here is what you are likely leaving on the table.

Quick Recap: Old Regime Only

All of these apply only if you have opted for the old tax regime. If you are on the new tax regime, you lose almost all deductions except NPS through employer and a few standard ones. If your deductions total more than Rs. 3.75 lakh (the breakeven point varies by income level), old regime likely saves you more.

1. Section 80D - Health Insurance Premium (Up to Rs. 75,000)

This is the most widely unused deduction for salaried employees under 35.

  • Rs. 25,000 for health insurance premium for self, spouse, and children.
  • Rs. 25,000 additional for health insurance premium for parents (under 60 years).
  • Rs. 50,000 if parents are senior citizens (60+), instead of Rs. 25,000.

Combined maximum: Rs. 75,000 per year if parents are senior citizens.

A family floater policy covering you, spouse, and two kids runs Rs. 15,000 to Rs. 25,000 per year. Adding a senior citizen parent plan adds another Rs. 20,000 to Rs. 35,000. Both are deductible and both are money you should be spending anyway for protection.

Tax saved at 30% bracket: Up to Rs. 22,500.

2. Section 80CCD(1B) - NPS Additional Contribution (Up to Rs. 50,000)

This is over and above the Rs. 1.5 lakh 80C limit. If you invest Rs. 50,000 additionally in NPS (National Pension System) Tier 1, you get another Rs. 50,000 deduction.

This deduction is available under both old and new tax regimes for contributions made by the employee.

NPS returns have historically been 9-11% per year for equity-heavy allocation. The lock-in is until retirement (with partial withdrawal allowed after 3 years for specific reasons), which makes it less flexible than ELSS - but the additional Rs. 50,000 deduction makes it powerful.

Tax saved at 30% bracket: Rs. 15,000.

3. Section 24(b) - Home Loan Interest (Up to Rs. 2 lakh)

If you have a home loan on a self-occupied property, the interest component of your EMI (not the principal) is deductible up to Rs. 2 lakh per year under Section 24(b).

On a Rs. 50 lakh home loan at 8.75% for 20 years, the interest in the early years is Rs. 4-4.3 lakh per year. You can claim Rs. 2 lakh of that as a deduction. The principal repayment goes under 80C.

Tax saved at 30% bracket: Rs. 60,000.

4. Section 80E - Education Loan Interest (No Upper Limit)

Paying an education loan for yourself, spouse, or children? The entire interest amount is deductible with no cap, for up to 8 years of repayment.

If your education loan interest this year is Rs. 1.2 lakh, that full Rs. 1.2 lakh is deductible.

Note: Only interest counts, not principal. And you must be the borrower (not the student, necessarily) to claim this.

Tax saved at 30% bracket: 30% of whatever interest you paid.

5. Section 80TTA / 80TTB - Savings Account Interest (Up to Rs. 10,000 / Rs. 50,000)

Section 80TTA allows a deduction of up to Rs. 10,000 on interest earned from savings accounts (not FDs, only savings accounts). If you are under 60 and earn Rs. 8,000 in savings account interest, the entire Rs. 8,000 is deductible.

If you are a senior citizen (60+), Section 80TTB gives you Rs. 50,000 deduction on interest from savings accounts, FDs, and RDs combined.

Most people with a reasonable savings account balance qualify for the full Rs. 10,000 deduction without even trying.

6. HRA Exemption - If You Rent and Have Not Claimed It Properly

If you live in a rented home and receive HRA as part of your salary, you can claim HRA exemption. The exempt amount is the lowest of:

  • Actual HRA received
  • 50% of basic salary (metro cities) or 40% (non-metro)
  • Actual rent paid minus 10% of basic salary

Many employees forget to submit rent receipts or do not structure their rent correctly. If you pay Rs. 20,000 per month rent and have a basic salary of Rs. 25,000 per month, you can potentially exempt Rs. 1.2 lakh to Rs. 1.5 lakh from tax.

If you pay rent to a parent, that is also valid - the parent then shows it as rental income in their ITR.

7. Section 80G - Donations (50% to 100% Deductible)

Donations to approved charitable organizations under Section 80G are deductible. Some organizations qualify for 100% deduction, others for 50%.

The PM Relief Fund, PM CARES, National Defence Fund, etc. offer 100% deductions. Charitable trusts and hospitals usually offer 50%.

If you donate Rs. 20,000 to a PM CARES-eligible fund, you deduct Rs. 20,000 from taxable income. Small amounts add up, especially near year-end.

Summary Table

Section Max Deduction Who Benefits Most
80D Rs. 75,000 Anyone with health insurance and senior citizen parents
80CCD(1B) Rs. 50,000 Anyone willing to lock into NPS for retirement
24(b) Rs. 2,00,000 Home loan borrowers
80E No limit Education loan borrowers
80TTA Rs. 10,000 Anyone with savings account interest
HRA Variable Salaried employees paying rent
80G Variable (50-100%) Donors

Bottom Line

Maxing 80C is a starting point, not the finish line. If you have health insurance, a home loan, or are contributing to NPS, you have access to Rs. 3-4 lakh in additional deductions beyond 80C. At a 30% tax rate, that is Rs. 90,000 to Rs. 1.2 lakh in annual tax savings. The forms and documentation are simple - your CA or the income tax portal will guide you through each one.
