Income Tax on Fixed Deposits: How TDS Works and How to Legally Reduce It
Fixed deposits are the most popular savings instrument in India — and one of the most tax-inefficient for anyone above the basic exemption limit. FD interest is added to your income and taxed at your slab. On ₹10 lakh in FDs at 7%, someone in the 30% bracket keeps just ₹4,888 of the ₹7,000 monthly interest. Here's how to understand FD taxation and how to reduce it legally.
How FD Interest Is Taxed
FD interest is taxable as "Income from Other Sources" — added to your total income and taxed at your marginal slab rate. This applies to:
- Regular bank FDs (all tenures)
- Corporate FDs
- Recurring deposits
- Post Office Time Deposits
The only exception: Tax Saver FDs (5-year) — the principal qualifies for 80C deduction, but the interest is still taxable. "Tax saver" refers to the principal, not the interest.
When TDS Is Deducted on FDs
| Type of Depositor | TDS Threshold (Annual Interest) | TDS Rate |
|---|---|---|
| Regular individuals (<60 years) | ₹40,000 | 10% (20% without PAN) |
| Senior citizens (60+ years) | ₹50,000 | 10% (20% without PAN) |
| Cooperative societies / trusts | ₹40,000 | 10% |
TDS is deducted per branch per bank (not per FD). If you have ₹20 lakh across 4 FDs at one SBI branch earning ₹1.4 lakh/year in interest, SBI deducts TDS on ₹1 lakh (above the ₹40,000 threshold).
The Accrual Tax Problem With Multi-Year FDs
For cumulative FDs (where interest is compounded and paid at maturity), the Income Tax Department taxes interest on an accrual basis — meaning each year's interest is taxable in that financial year, even though you receive it only at maturity. Many investors discover this when they file ITR and find their FD maturity year's interest suddenly pushed them into a higher bracket.
To avoid surprise tax bills, declare accrued interest each year in your ITR (even for cumulative FDs) and claim TDS credit from your Form 26AS. Don't wait until the FD matures.
Legal Ways to Reduce FD Tax
1. Form 15G/15H (No TDS if income below exemption): Submit Form 15G (under 60) or Form 15H (60+) to your bank at the start of each year if your estimated total income is below the taxable threshold. This prevents TDS from being deducted — but you must declare interest in your ITR regardless.
2. Split FDs across family members: Open FDs in your spouse's or parent's name if they're in a lower tax bracket. The interest is taxed in their hands. Note: clubbing provisions apply if you fund a spouse's FD — the interest is clubbed with your income. Parent FDs are not clubbed.
3. Use the ₹10,000 savings account interest deduction (80TTA): Interest from savings accounts (not FDs) up to ₹10,000 is deductible. Keep emergency funds in high-yield savings accounts rather than FDs where possible.
4. Senior citizens' 80TTB deduction: Senior citizens (60+) get a ₹50,000 deduction on interest from banks, post office, and cooperative banks under Section 80TTB. This makes FDs significantly more tax-efficient for retirees.
FAQ
Does TDS on FD mean I don't need to pay any more tax?
No. TDS is only a prepayment of tax. If your slab rate is 30% and TDS was deducted at 10%, you owe an additional 20% (plus cess) on the same interest income at self-assessment time. Failing to pay this leads to interest under Section 234.
What if TDS was deducted but my income is below the taxable limit?
File an ITR and claim the full TDS as refund. Alternatively, submit Form 15G/H next year to prevent TDS deduction at source.
Is NRE FD interest taxable in India?
No. Interest on NRE (Non-Resident External) fixed deposits is fully exempt from income tax in India for as long as the account holder maintains NRI status.
