1. Interest Income: A Comprehensive Tax Guide for Every Investor
Interest income in India comes from an enormous variety of sources: bank savings accounts, fixed deposits, recurring deposits, post office savings schemes, Senior Citizen Savings Scheme, bonds (government and corporate), debentures, Provident Fund, National Savings Certificates, peer-to-peer lending platforms, and overseas bank accounts. Each source has its own TDS rate, its own threshold, its own reporting in the ITR, and its own exemption possibility. For investors with multiple interest-bearing instruments -- which describes virtually every earning Indian -- navigating this landscape correctly is essential.
2. The Basic Rule: Interest Is Other Sources Income
Interest income, unless specifically exempt under Schedule II or Section 10(15), is taxable as income from other sources under Section 56(2) of ITA 2025 at the recipient slab rate. There is no separate LTCG-like concessional rate for interest -- it is always at the full slab rate (5%, 20%, or 30%). This makes interest income significantly less tax-efficient than equity capital gains (12.5% LTCG) for high-bracket investors, which has driven the increased interest in equity and hybrid investments over the past decade.
3. TDS Thresholds for Different Interest Types
| Interest Source | ITA 2025 Section | TDS Rate | Annual Threshold |
|---|---|---|---|
| Bank FD and RD interest | Section 393B | 10% | Rs 40,000 (Rs 50,000 for senior citizens) |
| Co-operative bank deposit interest | Section 393C | 10% | Rs 40,000 (Rs 50,000 for senior) |
| Post Office SCSS/TD interest | Section 393B equivalent | 10% | Rs 40,000 (Rs 50,000 for senior) |
| Listed debenture/bond interest | Section 393A | 10% | Rs 5,000 |
| Government securities interest | Section 193 | 10% | Rs 10,000 |
| Savings account interest (bank/post office) | No TDS on savings accounts | Nil | No TDS; taxpayer self-reports |
4. Form 15G and Form 15H: Preventing TDS
Taxpayers with interest income below the taxable threshold can submit self-declaration forms to prevent TDS deduction at source:
- Form 15G (for individuals below 60 and HUFs): Can be submitted when: (a) total estimated income for the year is below the basic exemption limit; AND (b) estimated tax liability is nil. Submit separately to each bank at the beginning of each financial year.
- Form 15H (for senior citizens 60+): Can be submitted when estimated tax liability on total income (including interest) is nil -- after all applicable deductions including Section 80TTB Rs 50K, standard deduction, and basic exemption. More widely usable than Form 15G.
- Consequences of incorrect submission: If the taxpayer submits Form 15G/15H but is actually taxable, interest and penalty apply on the unpaid TDS. Banks report all Form 15G/15H submissions to the IT Department -- these are verifiable.
5. AIS and Interest Income: The New Reality
All banks report interest income above threshold amounts via Statement of Financial Transactions (SFT) to the IT Department. This data appears in the taxpayer Annual Information Statement (AIS). Practical implications:
- Every FD interest above Rs 40,000 from any bank is reported and appears in AIS
- If you have multiple FDs across banks: ALL are reported; AIS shows total interest from each bank
- If interest appears in AIS but not in your ITR: automatic flag for potential scrutiny notice
- Always reconcile AIS with your own interest income records before filing ITR
- Include even small savings account interest that may not have TDS but appears in AIS
6. National Savings Certificate (NSC): Annual Accrual Taxation
NSC is a government savings instrument with 5-year maturity. Its interest tax treatment is unique:
- NSC interest accrues annually (notionally) even though it is paid only at maturity
- Each year accrual is TAXABLE as income from other sources in the year of accrual -- not just in the final year
- Example: NSC purchased 1 April 2022 for Rs 1 lakh at 7.7% interest. Year 1 (2022-23) accrual: Rs 7,700 -- taxable in 2022-23. Year 2 (2023-24) accrual: Rs 8,293 (on Rs 1,07,700 -- compounded) -- taxable in 2023-24, and so on.
- The annual accrual ALSO qualifies for Section 123 deduction in the year of accrual (since it is reinvested in NSC)
- At maturity: the final year interest is taxable; all prior-year interest has already been taxed
7. PPF Interest: Completely Exempt
Public Provident Fund (PPF) interest is one of the few completely tax-free interest incomes:
- PPF interest: exempt from income tax under Schedule II of ITA 2025 (EEE status -- Exempt at contribution, Exempt during accumulation, Exempt at withdrawal)
- No TDS on PPF interest
- No reporting required in ITR (it is exempt income not required to be declared separately)
- PPF lock-in: 15 years; partial withdrawals from year 7
- Annual contribution: minimum Rs 500, maximum Rs 1.5L per year
- PPF is one of the most tax-efficient long-term savings instruments -- the 7.1% (current rate) is effectively much higher on an after-tax basis compared to FD interest
8. Tax-Free Bonds: Section 10(15) Exemption
Certain government-guaranteed bonds issued in 2012-18 carry a specific income tax exemption under Section 10(15):
- Issuers: NHAI, IRFC, NHB, HUDCO, PFC, REC, IIFCL
- Interest: fully exempt from income tax under Section 10(15)(h) equivalent
- Bonds trade on stock exchanges (NSE, BSE) -- can be bought and sold at market prices
- Capital gains on sale of these bonds: taxable (the exemption is only for INTEREST, not for capital gains)
- Current availability: limited supply; traded at a premium; effective yield 4.5-5.5% but tax-free makes them competitive for 30% bracket investors (tax-equivalent yield 6.5-8%)
9. P2P Lending Interest: Emerging Category
Peer-to-peer (P2P) lending platforms (Faircent, Lendbox, RupeeCircle) generate interest income for lenders:
- Interest received: taxable as income from other sources at slab rate
- Platforms deduct TDS at applicable rates -- check each platform policy
- Bad debts from P2P: when a borrower defaults and the loan is declared irrecoverable, the principal and interest lost can potentially be claimed as a deduction when written off as irrecoverable bad debt (requires documentation of recovery attempts)
- P2P returns: higher than bank FD due to default risk; tax treatment same as bank FD interest
- High-bracket investors: P2P interest at 30% slab rate effectively reduces the risk-adjusted return -- factor this into P2P investment decisions
10. Overseas Bank Account Interest: Resident Taxation
Indian residents (ROR status) holding NRE accounts (converted to resident accounts after returning) or foreign bank accounts:
- NRE account on becoming resident: interest becomes taxable from the date of becoming resident (was exempt during NRI/RNOR period)
- RNOR status: foreign income (including foreign bank interest) still exempt during RNOR period
- ROR status: foreign bank interest fully taxable; convert foreign interest to INR at exchange rate and report in Schedule OS
- Foreign TDS (if any foreign bank deducts withholding tax): claim foreign tax credit via Form 67 on the IT Portal
- Schedule FA disclosure: all foreign bank accounts must be disclosed in Schedule FA of ITR by all ROR taxpayers
11. Interest Income Planning for Different Tax Brackets
A bracket-based approach to interest income:
- 5% or 20% bracket taxpayers: Bank FD interest is relatively efficient; explore PPF and NSC for tax-free and partially-exempt alternatives
- 30% bracket taxpayers: Bank FD interest at 30% = effective real return is low; consider: PPF (tax-free), tax-free bonds (Section 10(15)), or shifting to equity for appreciation-driven returns at 12.5% LTCG rate
- Senior citizens: Section 80TTB Rs 50K deduction makes the first Rs 50K of interest effectively tax-free; SCSS and FD are optimal for safety and Section 80TTB benefit
