← All fixed-income sectionsWhat it is
Post Office and National Small Savings products are a family of Government-backed schemes, not one investment. They include products for long-term saving, regular income, senior citizens and specific goals.

ReturnRates notified / scheme-specific
Key checkEligibility, lock-in, tax status
What can go wrong
- Credit risk is low because these are Government-backed schemes, but lock-in and premature-withdrawal rules can be significant.
- Some products have strict eligibility or annual contribution limits.
- Do not assume every small-savings product has the same tax treatment.
Tax in India
- PPF: interest and qualifying withdrawals/maturity are generally exempt; contribution deductions matter only under a regime that allows the relevant deduction.
- NSC, SCSS, Post Office Time Deposit, MIS, RD and similar schemes generally have taxable interest/returns, subject to product-specific rules. A 5-year Post Office Time Deposit can have deduction relevance under the old regime.
- Always separate “deduction on investment” from “taxability of interest.” A product can offer one without making the other tax-free.
What the example below measures
The example below focuses on the tax increase caused by this instrument’s return for people starting with ₹6 lakh, ₹12 lakh or ₹50 lakh of normal taxable income. It does not treat TDS as final tax.
Post Office TD tax: what happens to a ₹6L, ₹12L or ₹50L income person?
This is an instrument-specific illustration, not the same generic tax chart repeated on every page.
Example used on this page: Because this page covers several schemes with different tax rules, the persona example uses a 5-year Post Office Time Deposit: ₹5,00,000 at an illustrative 7.5% → ₹37,500 annual interest. Existing income below means normal taxable income before this investment return is added. Assumes a resident individual, no special-rate income, and includes 4% Health & Education Cess.
Existing taxable income before Post Office TD return₹6,00,000
After adding return: ₹6,37,500
Income becomes ₹6,37,500. Because normal-rate total income is still within ₹12 lakh, the available resident-individual rebate can keep final tax at nil in this simplified example.
Existing taxable income before Post Office TD return₹12,00,000
After adding return: ₹12,37,500
Income becomes ₹12,37,500. ₹12 lakh is exactly the rebate cut-off. Marginal relief limits the sudden tax jump; 4% cess is then added. This is a threshold effect, not a normal 104% tax rate.
Existing taxable income before Post Office TD return₹50,00,000
After adding return: ₹50,37,500
Income becomes ₹50,37,500. ₹50 lakh is exactly the surcharge threshold. Marginal relief reduces the surcharge jump just above ₹50 lakh; 4% cess is then added.
Why the ₹12L and ₹50L examples can look surprising: both people start exactly on a tax boundary before the Post Office TD return is added. At ₹12 lakh, the 87A rebate boundary is crossed; at ₹50 lakh, the surcharge boundary is crossed. Marginal relief softens each jump, but 4% cess still applies. A person whose total income is comfortably inside a slab will normally see a much more familiar marginal tax effect. These cards are designed around your exact “₹6L / ₹12L / ₹50L income person then invests” question.
Small-savings taxation is mixed: PPF and Sukanya Samriddhi are generally tax-exempt on qualifying interest/maturity, while Time Deposit, MIS, SCSS, RD, NSC/KVP and similar products can have taxable interest/returns under product-specific rules. Always check the exact scheme, not just “Post Office”.
PPF example — generally exempt interestIllustration: ₹1,50,000 contribution and 7.1% annual interest = ₹10,650 interest. PPF interest is generally exempt; contribution deduction is a separate old-regime question.
Sukanya Samriddhi — generally exempt interest/maturityQualifying interest and maturity are generally exempt. The account has eligibility, contribution and withdrawal rules, so compare it as a goal-linked scheme rather than a normal deposit.
Tax & bond words — explained simply
No jargon without meaning. These are the terms used on this Post Office TD page.
Taxable interestInterest that is added to normal taxable income, as with many Post Office Time Deposit, MIS and SCSS receipts.
Exempt interestInterest that is not included in taxable income when the scheme and conditions qualify, as is generally the case for PPF and Sukanya Samriddhi interest.
DeductionAn amount allowed to be subtracted while computing taxable income. A deduction on investment is different from exemption of the interest/maturity amount.
80CA deduction provision used mainly under the old regime for qualifying investments/expenses, subject to conditions and limits. Choosing a product for “80C” does not automatically make its interest tax-free.
TDSTax deducted before interest is paid/credited. TDS is only credit toward final tax.
CessA 4% Health & Education Cess charged on income tax plus surcharge, if any.
