FD Interest Tax & TDS in 2026: What You Actually Keep

How FD interest and TDS interact

Fixed-deposit interest is generally taxable according to the investor’s applicable tax rules even when the bank does not deduct TDS. For bank/co-operative bank/post-office interest, the section 194A threshold from 1 April 2025 is ₹50,000 for non-senior citizens and ₹1 lakh for senior citizens. The threshold controls TDS—not whether the interest itself is taxable.

Before comparing FD post-tax returns

The three numbers an FD investor should compare

• TDS threshold ≠ tax exemption.
• Current bank/post-office threshold: ₹50,000 for others, ₹1 lakh for senior citizens.
• Interest is generally taxed in the year/manner required by applicable income-tax rules.
• Compare post-tax FD yield, not only the headline rate.

TDS threshold in 2026

These thresholds apply from 1 April 2025 under the current guidance. For other payers, a different threshold can apply. Banks using core banking generally aggregate relevant interest across branches rather than treating each branch as a separate fresh threshold.

Gross rate versus post-tax return

Suppose a ₹10 lakh FD earns 7% for a year: gross interest is ₹70,000. Ignoring compounding and assuming the interest falls in a 20% marginal tax bracket plus 4% cess, an illustrative tax cost is ₹14,560, leaving about ₹55,440 after tax. That is an effective after-tax return of roughly 5.54% for this simplified example.

Why no TDS does not mean no tax

If your interest is ₹40,000 and you are below the relevant TDS threshold, the bank may not withhold tax. But the interest can still be part of your taxable income. Conversely, if TDS is deducted, it is a credit against final tax—not necessarily the final amount owed.

What to compare before choosing an FD

• Post-tax yield based on your own marginal tax position.
• Premature-withdrawal penalty and liquidity needs.
• Deposit tenure and reinvestment risk.
• Bank concentration and applicable deposit-insurance limits.
• Whether an alternative government savings scheme has different liquidity/tax features.

Move from headline rate to post-tax return

Reconcile interest certificate, AIS/26AS and the bank’s TDS entries before filing. If tax was deducted, claim the corresponding credit against your final liability. If you are eligible to submit Form 15G or 15H, the declaration affects deduction at source, not the underlying rule that decides whether the interest belongs in taxable income.

TDS on FD interest is only a collection mechanism; it is not the final tax rate on the deposit. The bank looks at the applicable deduction threshold and declarations, while your return ultimately taxes interest according to the law and your total taxable income. No TDS deduction does not automatically mean the interest is tax-free.

When comparing FDs, calculate the post-tax effective yield. A 7.5% FD for someone taxed at 30% has a very different after-tax outcome from the same FD for someone with little or no taxable income. Also compare premature-closure penalties, compounding frequency, deposit insurance limits and whether you need periodic interest or maturity value.

Suppose a non-senior investor earns ₹80,000 of bank-deposit interest. The bank may deduct TDS under the current rules, but the investor's final tax could be higher or lower depending on the slab rate and other income. A person whose total tax liability is nil may be able to use the prescribed declaration process if eligible, but should not submit a declaration merely to avoid cash-flow inconvenience.

For bank time deposits, the current section 194A threshold is ₹50,000 of annual interest for most resident depositors and ₹1,00,000 for resident senior citizens. Crossing the threshold can trigger TDS, but the threshold does not convert the interest below it into tax-free income. FD interest is generally included in taxable income and taxed according to the applicable rules.

Calculate the FD return after both TDS and final tax

Estimate the year's total interest across deposits, apply the applicable TDS rule, and then compute the final income-tax liability at your actual slab rate. If TDS exceeds the final liability it may be refundable; if it is lower, additional tax may be due. This is why the amount credited by the bank is not automatically the after-tax return.

When TDS and final tax move in different directions

Splitting deposits across branches of the same core-banking institution does not necessarily recreate a fresh TDS threshold at every branch. More importantly, staying below the TDS threshold does not turn taxable interest into exempt income.

Tax mistakes that overstate FD income

• Projecting today’s notified interest rate unchanged for decades without saying it is an assumption.
• Ignoring contribution limits, lock-ins or withdrawal conditions.
• Comparing gross interest while ignoring tax treatment.
• Using an old scheme rule after a notification has changed.
• Assuming government backing makes every scheme equally liquid or suitable.

If the FD pays interest out monthly or quarterly, the quoted annual rate does not mean every rupee compounds inside the deposit. For a maturity FD, interest can compound according to the product terms; for a payout FD, cash leaves the deposit and must be reinvested separately if you want compounding. When comparing two deposits, match payout frequency as well as rate, tenure and tax.

One more number to compare: reinvestment yield

For multi-year deposits, also ask what happens when interest or principal must be reinvested. A high current FD rate does not guarantee the same rate at renewal. When comparing a ladder with one long deposit, consider both tax drag and the possibility that future reinvestment rates are lower or higher.
