Section 80C / 80D Tax-Saver Planner

Tax-saving deductions are the most direct lever an individual taxpayer has over their tax bill, but they are widely misunderstood — both in how much they save and in which regime they apply to. A deduction reduces your taxable income, so the tax it saves is the deduction multiplied by your marginal slab rate: a ₹1.5 lakh Section 80C investment saves ₹45,000 for someone in the 30% bracket but only ₹7,500 for someone in the 5% bracket. Crucially, all of the deductions this planner covers — 80C, 80CCD(1B), 80D, 24(b), and 80TTA/80TTB — are available only under the old tax regime. Under the new regime, which has been the default since FY2023-24, these are not available at all, so the entire exercise of tax-saving investment only pays off if the old regime is the cheaper choice for you in the first place.

Section 80C is the headline deduction and the one most people start with. It bundles a wide range of instruments — Employee Provident Fund contributions, Equity-Linked Savings Schemes, Public Provident Fund, life-insurance premiums, five-year tax-saving fixed deposits, principal repayment on a home loan, and children’s tuition fees — under a single combined ceiling of ₹1.5 lakh. Because so many everyday commitments already count toward it (your EPF deduction and home-loan principal, for instance), many salaried people are closer to the limit than they realise, which is why seeing your remaining headroom matters more than chasing new investments blindly. On top of 80C, Section 80CCD(1B) offers a separate ₹50,000 deduction for National Pension System contributions — a true addition to the ₹1.5 lakh, not a slice of it — making the combined retirement-linked deduction up to ₹2 lakh.

The health and interest deductions round out the picture. Section 80D covers health-insurance premiums, with limits that step up by age: ₹25,000 for a policy covering yourself and family when you are under 60, rising to ₹50,000 when the insured is a senior citizen, and you can claim a second, separate 80D limit for insuring your parents — so a person under 60 insuring senior parents can claim ₹25,000 plus ₹50,000. Section 24(b) allows up to ₹2 lakh of interest on a home loan for a self-occupied property, a substantial deduction entirely separate from the 80C principal. Finally, Sections 80TTA and 80TTB cover interest from savings and deposits — ₹10,000 for those under 60 under 80TTA, or a more generous ₹50,000 for senior citizens under 80TTB — and the two are mutually exclusive, so you claim one or the other depending on your age, never both. This planner brings all of these together so you can plan the full set, not just 80C in isolation.

Enter your income and age. The planner needs your gross annual income to compute the tax you save, and your age because two of the deductions — 80D health insurance and the 80TTA/80TTB savings-interest deduction — have higher limits for senior citizens. The age toggles make sure the caps applied to you are the right ones, and that the engine claims 80TTB rather than 80TTA once you are 60 or over.

Fill in what you have already committed under each section. For each deduction — 80C, the extra NPS under 80CCD(1B), health insurance under 80D for yourself and separately for your parents, home-loan interest under 24(b), and savings interest — enter the amount you have invested or paid this year. You can put in your real current numbers to see where you stand, or experiment with higher figures to plan where to direct your next rupee.

Read your headroom for each section. The tool shows, per section, how much of your declared amount is actually allowed (capped at the legal limit) and how much headroom remains before you hit that cap. If you have declared ₹2 lakh under 80C, you will see only ₹1.5 lakh allowed and zero headroom; if you have declared ₹80,000, you will see ₹70,000 of remaining room — a concrete prompt for where further tax-saving investment still helps.

Check your total deductions and the tax you save. The result shows your total declared amount and your total allowed amount separately — so over-declaring is obvious — and then the actual old-regime tax saved, computed by running your income with and without the allowed deductions through the same engine as our Income Tax Calculator. This is the number that matters: not how much you invested, but how much tax those investments removed.

Confirm the old regime is right for you first. Because every deduction here applies only under the old regime, the planner is only useful if the old regime is cheaper for you than the new one. Use the Income Tax Calculator linked below to compare the two regimes for your income; if the new regime wins even before deductions, tax-saving investments will not reduce your tax, and you should choose investments on their own merits instead. Always confirm current limits on the income-tax portal and consult a CA for personal advice.
