Post Office FD vs Bank FD: Which Fixed Deposit Fits Your Needs?

The Deposit Insurance and Credit Guarantee Corporation (DICGC) insures eligible deposits in insured banks up to Rs. 5,00,000 per depositor per bank, including principal and accrued interest.

Deposits held across different branches of the same bank are aggregated when determining the insurance limit. Deposits held with different banks are separately covered, subject to the applicable rules.

This means a Rs. 5 lakh DICGC limit should not be interpreted as Rs. 5 lakh for every FD account at the same bank. The coverage is based on the depositor's deposits held in the same right and capacity with that bank.

DICGC insurance is also different from the Government backing associated with small-savings schemes.

The three options can be compared across the factors that generally matter to fixed-income savers.

The important distinction is that interest rate and safety structure are separate considerations. A higher quoted rate does not by itself indicate a higher level of protection.

The Post Office Time Deposit has government-notified rates. Bank FD rates are determined individually by banks and can differ by tenure, customer category and deposit amount.

For the July–September 2026 quarter, the Post Office rates are:

A Bank FD comparison therefore needs to use the rate offered by a specific bank for the same tenure and depositor category rather than an unspecified market average.

For example, a 3-year Bank FD should be compared with the 3-year Post Office rate of 7.10%, while also considering the bank's senior citizen rate, premature-closure rules and applicable DICGC coverage.

No. The Post Office Time Deposit does not have a separate senior-citizen interest rate.

The same notified rate applies to eligible depositors irrespective of age.

Banks and corporate FD issuers may provide additional interest to senior citizens. The amount varies between institutions and should therefore be checked against the issuer's current rate card.

For example, Bajaj Finance currently offers up to 7.75% p.a. for customers below 60 and up to 8.15% p.a. for senior citizens, with the senior-citizen differential going up to 0.40% percentage points. Its published rates are applicable to deposits from Rs. 15,000 to Rs. 3 crore from w.e.f 07 October, 2026

Both of the following can qualify for a deduction under Section 80C, subject to the applicable conditions:

1. 5-Year Post Office Time Deposit
2. 5-Year Bank Tax-Saving Fixed Deposit

The combined deduction limit under Section 80C is Rs. 1.50 lakh. Section 80C deductions are generally relevant when the taxpayer opts for the old tax regime and meets the applicable conditions.

A tax-saving FD generally has a mandatory five-year lock-in. Premature closure is restricted compared with a normal FD.

The tax benefit applies to the eligible investment amount; interest earned on an FD remains subject to the applicable income-tax rules.

Interest earned from FDs is generally taxable as income according to the applicable tax provisions and the taxpayer's circumstances.

What are the 2026 TDS thresholds?

For FY 2026–27, the threshold for TDS on interest from banks, post offices and eligible cooperative banks is:

The higher senior-citizen threshold was introduced through the tax changes applicable from 1 April 2025.

For interest from other categories of payers, including certain corporate deposits, a different threshold can apply. The applicable rules should therefore be checked based on the issuer.

TDS is not the same as the final income-tax liability. It is a tax deduction at source that can be adjusted against the taxpayer's final tax liability.

A resident senior citizen can claim a deduction of up to Rs. 50,000 on eligible interest income from deposits under Section 80TTB, subject to the applicable conditions and tax regime. Eligible deposits include bank and Post Office deposits.

The deduction is separate from the TDS threshold.

For example, an eligible senior citizen may have a Rs. 1,00,000 TDS threshold for applicable bank/Post Office interest, while the Section 80TTB deduction remains capped at Rs. 50,000

Yes, but the withdrawal rules are different from those of a typical Bank FD.

A Post Office Time Deposit cannot generally be prematurely closed before six months from the date of opening.

After six months and before one year, premature closure is permitted under the scheme rules, with interest calculated at the applicable Post Office Savings Account rate for the completed period.

For deposits of two, three or five years that are closed after one year but before maturity, the interest calculation is made at the prescribed reduced rate under the applicable Time Deposit rules.

Therefore, the earlier statement that the rate is always “2% below the contracted rate” should not be used as a blanket rule without specifying the applicable scheme provision and withdrawal period.

Bank FD premature withdrawal rules are determined by the individual bank and the product terms.

Depending on the bank and deposit type, premature closure may involve:

• A reduction in the applicable interest rate
• A premature-closure penalty
• Interest being recalculated for the period the deposit actually remained with the bank
• Restrictions on premature closure for certain special deposits

The specific bank's terms should therefore be checked before opening an FD if early liquidity is important.

A corporate FD can offer a different combination of interest rate, tenure and issuer risk.

For example, Bajaj Finance's current FD rates range up to 7.40% p.a. for regular customers and 7.75% p.a. for senior citizens, depending on tenure and payout option. Deposits are currently accepted from Rs. 15,000 to Rs. 3 crore per deposit under the published rate structure.

The deposits are rated CRISIL AAA/STABLE and [ICRA]AAA(Stable). These ratings indicate the rating agencies' assessment of the credit quality of the relevant instrument; they should not be described as a sovereign guarantee or DICGC insurance.

Current Bajaj Finance FD rates

These are cumulative/at-maturity rates in the current published rate table and are valid for deposits from Rs. 15,000 to Rs. 3 crore from 1 May 2026. Non-cumulative payout rates differ.

A useful comparison should go beyond the headline interest rate.

Consider the safety structure

A Post Office Time Deposit and a Bank FD do not use the same protection mechanism.

Post Office deposits form part of the Government's small-savings framework, while eligible Bank FDs receive DICGC insurance up to Rs. 5 lakh per depositor per bank. Corporate FDs rely on the financial strength and repayment capacity of the issuing institution.

Compare the same tenure

A 1-year FD should be compared with another 1-year FD rather than a 3-year or 5-year product.

The interest rate can vary substantially with tenure.

Check senior citizen rates

For a senior citizen, compare the actual rate available for the same tenure rather than assuming every FD provides the same additional interest.

Consider liquidity

If the money may be required before maturity, check:

• Minimum lock-in period
• Premature closure eligibility
• Penalty or reduced interest
• Loan or overdraft facility, if available
• Processing time for accessing funds

Consider taxation

Compare the post-tax return rather than only the advertised interest rate.

The tax treatment depends on the depositor's income, tax regime, applicable deductions and TDS provisions.

There is no single FD structure that fits every depositor. The relevant features depend on the purpose of the deposit.
