Free Investment Calculators for Indian Investors
India's Income Tax Act provides numerous deductions and exemptions that can significantly reduce your tax liability — but only if you plan strategically. This guide covers every major tax-saving section available under the old tax regime, helping you save up to Rs 4-5 lakh in taxes annually through legitimate deductions. Whether you are a salaried employee, self-employed professional, or business owner, understanding these deductions is essential for efficient financial planning.
Since FY 2023-24, India offers two tax regimes. The new regime is the default with lower slab rates but almost no deductions. The old regime allows all deductions listed in this guide. Choose the old regime if your total deductions exceed Rs 3-4 lakh (which is common for salaried employees with home loans, insurance, and investments).
Section 80C is the most widely-used deduction, offering Rs 1.5 lakh annual deduction across multiple investment options. Here is a comparison of all eligible instruments:
| Instrument | Returns | Lock-in Period | Risk | Tax on Returns |
|---|---|---|---|---|
| ELSS Mutual Funds | 12-15% | 3 years (shortest) | High (equity) | 10% LTCG above Rs 1.25L |
| PPF | 7.1% | 15 years | Zero (govt backed) | Fully tax-free (EEE) |
| EPF (employee share) | 8.25% | Till retirement | Zero | Tax-free after 5 yrs |
| NPS (under 80CCD(1)) | 8-12% | Till age 60 | Low-Medium | 60% tax-free |
| Tax-Saver FD | 6.5-7% | 5 years | Zero | Interest fully taxable |
| NSC (National Savings Certificate) | 7.7% | 5 years | Zero (govt backed) | Interest taxable (but reinvested interest qualifies for 80C) |
| SCSS (Senior Citizens) | 8.2% | 5 years | Zero (govt backed) | Interest taxable |
| Sukanya Samriddhi (daughters) | 8.2% | 21 years | Zero | Fully tax-free (EEE) |
| Life Insurance Premium | 4-6% | Policy term | Zero | Tax-free (if premium < 10% of sum assured) |
| Children Tuition Fees | N/A | N/A | N/A | N/A (expense, not investment) |
| Home Loan Principal | N/A | N/A | N/A | N/A (expense) |
Best strategy for most investors: Fill your 80C limit with ELSS (Rs 1.5L in monthly SIPs of Rs 12,500) for maximum growth potential with the shortest 3-year lock-in. If EPF already takes Rs 50,000-1,00,000, invest the remaining in ELSS. PPF is excellent if you want guaranteed, tax-free returns as part of your debt allocation.
This is the single most valuable deduction that many taxpayers miss. NPS contributions up to Rs 50,000 qualify for an additional deduction under Section 80CCD(1B) — completely over and above the Rs 1.5 lakh 80C limit. This saves:
No other investment instrument in India offers a deduction beyond the Rs 1.5L 80C limit (except Section 80D for health insurance). This makes NPS uniquely attractive for high-income taxpayers seeking to maximise deductions.
Health insurance premiums are deductible under Section 80D, with limits depending on age:
| Category | Deduction Limit | Details |
|---|---|---|
| Self + Family (below 60) | Rs 25,000 | Premium for self, spouse, and dependent children |
| Parents (below 60) | Rs 25,000 | Additional deduction for parents' health insurance |
| Parents (60 or above) | Rs 50,000 | Higher limit for senior citizen parents |
| Self (60+) + Parents (60+) | Rs 1,00,000 | Maximum: Rs 50,000 for self + Rs 50,000 for parents |
| Preventive Health Check-up | Rs 5,000 | Included within the above limits (not additional) |
Tip: A person below 60 paying health insurance for themselves (Rs 25,000) and senior citizen parents (Rs 50,000) can claim a total deduction of Rs 75,000 under Section 80D — saving Rs 23,400 in tax at the 30% bracket.
Interest paid on a home loan for a self-occupied property is deductible up to Rs 2 lakh per financial year under Section 24(b). Key points:
If you receive House Rent Allowance (HRA) as part of your salary and pay rent, you can claim HRA exemption. The exempt amount is the minimum of:
Example: Basic salary Rs 60,000/month, HRA Rs 24,000/month, rent paid Rs 25,000/month (metro city). Exempt HRA = minimum of (Rs 24,000, Rs 30,000, Rs 19,000) = Rs 19,000/month = Rs 2,28,000/year exempt from tax.
Interest paid on education loans (for self, spouse, or children) is fully deductible under Section 80E with no maximum limit. The deduction is available for 8 years from the year you start repaying the loan, or until the interest is fully repaid — whichever is earlier. This applies to loans taken for higher education in India or abroad from recognised financial institutions.
Here is a comprehensive tax-saving plan that maximises deductions for a salaried professional earning Rs 15-25 lakh per annum:
Instead of investing Rs 1.5 lakh in a lump sum in March, spread your 80C investments throughout the year via SIPs:
Total monthly outflow for tax saving: approximately Rs 17,000 — and every rupee is also building your long-term wealth or providing essential protection.
