When I speak to investors about fixed deposits, the most common surprise is not the rate—it’s the tax. An FD feels straightforward: I deposit money, the bank pays interest, and I receive the maturity amount. But from a tax perspective, FD interest is treated like regular income, and that changes how I should plan my cash flows and my year-end tax bill.
1) FD interest is taxable even if I don’t “withdraw” it
The interest I earn on a fixed deposit is taxable in my hands as income (generally under “Income from Other Sources”). The important nuance is timing: even in a cumulative FD (where interest is reinvested and paid at maturity), interest is typically credited/accrued periodically and can become taxable for that financial year. In other words, taxation is linked to “earning/credit,” not merely to when I finally receive the money.
2) TDS is not the final tax—it’s only a collection mechanism
Banks often deduct TDS (tax deducted at source) on FD interest once my interest crosses certain limits. That deduction can feel like “tax paid,” but I treat it as an advance collection. My final tax depends on my slab rate, after considering my total income and eligible deductions. If my slab rate is higher than the TDS deducted, I may still owe additional tax when filing my return. If my slab rate is lower (or my total tax liability is nil), I may be eligible for a refund after filing.
3) The thresholds: when does the bank start deducting TDS?
For interest on time deposits, the Income Tax Department’s TDS tutorial (as amended by Finance Act, 2025) lays out clear thresholds. Up to 31 March 2025, TDS applied beyond ₹40,000 for non-seniors and ₹50,000 for senior citizens (for banks/post offices/co-operative banks). From 1 April 2025, the threshold is ₹50,000 for others and ₹1,00,000 for senior citizens for banks/post offices/co-operative banks.
Two points I always remember:
- Once my interest exceeds the threshold, TDS can be deducted on the entire interest amount, not only the excess.
- Thresholds are applied with respect to the payer (for example, the bank), and core banking adoption affects whether it’s computed branch-wise.
4) How I can avoid unnecessary TDS (when eligible)
If my total income is below the taxable limit (or my final tax liability is nil), I may submit Form 15G (non-senior) or Form 15H (senior citizen) to request the bank not to deduct TDS—subject to eligibility rules. The Income Tax Department tutorial explains this mechanism and the broad conditions around these declarations.
5) Practical planning I actually follow
- I treat FD interest as taxable cash flow, not “bonus income.”
- I track interest credited across all deposits and reconcile it with my tax statements before filing.
- If I’m a senior citizen, I also check whether I can claim the Section 80TTB deduction (up to ₹50,000 on eligible deposit interest), which can reduce my taxable interest.
- I avoid tax surprises by setting aside money for taxes if I’m likely to be in a higher slab than the TDS rate.
To keep this simple: the return on an fd is not just the interest rate on paper—it’s the interest rate after tax. Once I internalize that, I’m able to use fixed deposits more intelligently within my overall plan.
