Post Office Time Deposit
Also written POTD · Post Office Time Deposits · Post office fixed deposit · POTD account
A government-guaranteed post office deposit of one, two, three or five years with a Rs 1,000 minimum and no maximum, of which only the five-year deposit qualifies for a tax deduction.
In plain language
The Post Office Time Deposit is the post office's version of a fixed deposit. The workbook says so directly: POTDs are similar to fixed deposits of commercial banks.
Four terms are on offer — one year, two years, three years and five years. The minimum deposit is Rs 1,000 and there is no maximum. The account can be held singly, or jointly by a maximum of two holders, and an individual can hold any number of deposits.
The risk is low, because the interest and principal are guaranteed by the Government of India.
One detail carries most of the exam weight. Only the five-year deposit qualifies for a tax deduction — and even that is unavailable under the new tax regime. The one, two and three-year deposits get nothing. The interest earned is taxable in every case.
And the deposit can be transferred from one post office to another, with early withdrawal entailing a penalty in the form of lower interest.
How it works
The terms.
| Feature | Post Office Time Deposit |
|---|---|
| Nature | A debt-oriented investment |
| Terms available | 1 year, 2 years, 3 years and 5 years |
| Holding | Singly, or jointly by a maximum of two holders |
| Number of deposits | Any number |
| Minimum deposit | Rs 1,000 |
| Maximum deposit | None |
| Risk | Low — interest and principal guaranteed by the Government of India |
| Liquidity | Transferable between post offices; early withdrawal entails a penalty in the form of lower interest |
| Tax on investment | Only the 5-year deposit qualifies under section 123 read with Schedule XV of the Income-tax Act, 2025 (corresponding to section 80C of the 1961 Act), subject to conditions — and not available under the new tax regime under section 202 (corresponding to section 115BAC) |
| Tax on interest | Taxable, and no tax is deducted at source |
A contradiction in the workbook, and you must carry both sides. The reset frequency is stated two different ways:
| Where | What it says |
|---|---|
| Chapter 6, accumulation-stage description of POTD | The interest on the deposits is reset each year by the government, and interest rates are compounded quarterly |
| Chapter 6, distribution-stage description of POTD | The interest rates on these accounts are reset every quarter |
| Chapter 1, section 1.2.4 | Small savings schemes such as NSC and post office time deposits are periodically reset (every quarter) |
Two of the three passages say quarterly and one says annually. Neither figure is safe to discard: cite the chapter if the point arises, and note that the weight of the workbook — two passages against one — sits with the quarterly reset. This is a reset in the reset-linked sense: the rate is re-fixed, while the capital is guaranteed and does not move.
Compounding and payout, which are also stated twice. The accumulation-stage passage says interest is compounded quarterly. The distribution-stage passage says the interest is paid annually for all deposits. Those are compatible — quarterly compounding with an annual payout — and together they explain why POTD appears on the workbook's list of income-stage products.
Its role in the distribution stage. Chapter 6 lists POTD among the products used to generate income in retirement, alongside the Senior Citizens Saving Scheme, the Post Office Monthly Income Scheme and bank deposits. It gives guaranteed income for the term of the deposit, and notes that except for POMIS there is no upper limit on the amount that can be invested. The risk it names is reinvestment risk: the money has to be re-invested on maturity and the interest rates at that time may be lower. So a retiree relying on POTD income must plan to reinvest the funds on maturity to ensure continued income at the prevalent rates.
A worked example
Mr Rane, 61, has Rs 24,00,000 to place for retirement income and wants sovereign safety.
He builds a ladder across the four available terms, so that something matures every year and he is never forced to reinvest the whole amount in one rate environment.
| Deposit | Term | Amount | Tax deduction on investment? |
|---|---|---|---|
| A | 1 year | Rs 6,00,000 | No |
| B | 2 years | Rs 6,00,000 | No |
| C | 3 years | Rs 6,00,000 | No |
| D | 5 years | Rs 6,00,000 | Yes, under section 123 read with Schedule XV — old regime only |
All four are above the Rs 1,000 minimum, and there is no maximum to worry about. He holds D jointly with his wife, which the maximum of two holders permits.
Only deposit D gives him a deduction on the amount invested, and only if he files under the old regime. The interest on all four is taxable, with no TDS — so he must set the tax aside himself.
Illustrative interest at 7.1 percent on Rs 24,00,000 = about Rs 1,70,400 a year
TDS deducted = Nil
Tax at his slab, payable by him = his own liability
The reinvestment risk, one year later. Deposit A matures. Rates have fallen, and the best POTD rate on offer is now lower than the one he locked in. The workbook names exactly this: the money has to be re-invested on maturity and the interest rates at that time may be lower. Because he laddered, only Rs 6,00,000 — a quarter of the corpus — is exposed to that lower rate, not the whole Rs 24,00,000. The ladder is his version of the same idea the workbook calls staggering income investments.
The early-exit cost. In year two he needs Rs 3,00,000 in a hurry and considers breaking deposit C. He can, and the deposit is also transferable between post offices if he moves — but early withdrawal entails a penalty in the form of lower interest. He breaks deposit B instead, which has less remaining term and therefore less accrued benefit to give up.
Why NISM asks about it
Chapter 6 covers the Post Office Time Deposit twice — once among the accumulation-stage products, with the full feature list, and again among the distribution-stage income products, with the nature of income, flexibility, reinvestment risk and taxability. Chapter 2, section 2.10.4, lists it under Post Office Schemes and Deposits. Chapter 1, section 1.2.4, uses it as an example of a reset-linked instrument.
Expect the recall numbers: terms of 1, 2, 3 and 5 years, a Rs 1,000 minimum, no maximum, a maximum of two joint holders, and any number of deposits. The highest-value single fact is that only the 5-year deposit qualifies for the deduction, and that the deduction is not available under the new tax regime. Expect also what risk does a retiree relying on POTD income bear (reinvestment risk), and the early-withdrawal consequence (a penalty in the form of lower interest).
Common exam traps
- Only the 5-year deposit gets the deduction, and only under the old regime. The 1, 2 and 3-year deposits get nothing at all, and section 202 of the 2025 Act (corresponding to section 115BAC) removes it under the new regime.
- The interest is taxable in every case, including on the 5-year deposit. A deduction on the investment is not an exemption on the income. And there is no TDS, so the tax does not take care of itself.
- The workbook contradicts itself on the reset frequency. One Chapter 6 passage says the rate is reset each year; another Chapter 6 passage and Chapter 1 both say every quarter. State both and cite the chapter rather than picking one.
- Compounded quarterly, paid annually. Both statements appear, in different sections, and they are not in conflict.
- Maximum two joint holders here; three adults on a Post Office Recurring Deposit. Two different limits in the same chapter.
- No maximum deposit — except that POMIS has one. The workbook is explicit that among these products only POMIS carries an upper ceiling.
- The risk is reinvestment risk, not price risk. Capital is guaranteed; what is not guaranteed is the rate available when the deposit matures.
- Early withdrawal is permitted but costly. The penalty takes the form of lower interest, not a loss of principal.
