You invest in an FD expecting safe and steady returns. The bank promises a decent interest rate, and everything seems straightforward. That’s until you notice your credited interest is lower than expected.
What happened differently? It is the TDS. Tax Deducted at Source (TDS) quietly reduces your earnings before the money even reaches you. If you’ve never calculated your FD returns after tax, you might be overestimating your gains. Read through to know how TDS actually impacts your investment.
What is TDS on FD Interest?
TDS stands for Tax Deducted at Source. It simply means that the bank deducts tax on the interest you earn from your Fixed Deposit before crediting it to your account.
If your total FD interest in a financial year crosses the applicable threshold, the bank deducts TDS. These thresholds were raised with effect from FY 2025-26, to ₹50,000 for most depositors and ₹1,00,000 for senior citizens. They are revised from time to time, so confirm the figure for the year you are filing. The usual TDS rate is 10% if you have submitted your PAN details. If PAN is not provided, the deduction can go up to 20%.
It is important to understand that TDS is not your final tax. Your actual tax liability depends on your income tax slab. Using a Fixed Deposit Calculator can help you estimate your real, post-tax returns more clearly.
How TDS Impacts Your Returns?
Immediate Reduction in Payout
When you invest in a Fixed Deposit, the bank calculates the interest earned and then deducts TDS (if applicable) before crediting the amount to your account. This means you do not receive the full interest earned.
For example:
- FD Investment: ₹10,00,000
- Interest Rate: 7%
- Annual Interest: ₹70,000 — above the threshold, so TDS applies
- TDS at 10%: ₹7,000
- Net Amount Credited: ₹63,000
So although ₹70,000 was earned, only ₹63,000 is credited. Note the order of events: if the interest had been below the threshold — say ₹35,000 — no TDS would have been deducted at all, and the full amount would have been credited.
Impact Based on Your Tax Slab
- If you fall under the 5% tax slab, you may claim a refund while filing your returns.
- If you are in the 20% or 30% slab, you will have to pay additional tax beyond the 10% already deducted.
- If your income is below the taxable limit, submitting Form 15G (or 15H for senior citizens) can help prevent TDS deduction.
Impact on Compounding
If your FD is cumulative and interest is reinvested, understanding how TDS works helps you plan your compounding strategy more effectively. By factoring in tax deductions in advance, you can set realistic return expectations and explore ways to optimise long-term wealth growth.
Ways to Minimise or Manage TDS Impact
While TDS cannot always be avoided, you can reduce its impact with smart planning.
- Submit Form 15G/15H: If your total income is below the taxable limit, submit Form 15G (or Form 15H for senior citizens) to avoid TDS deduction.
- Spread FDs Across Family Members: Where legally applicable, distributing FDs among eligible family members can help keep individual interest income below the TDS threshold.
- Choose Cumulative FDs Strategically: Opting for cumulative FDs can help manage when you receive interest and plan your taxes better.
- Monitor Form 26AS Regularly: Check your Form 26AS to verify TDS deductions and make sure that you claim any eligible refund while filing returns.
- Opt for Proper Tax Planning: Plan your overall investments in line with your income tax slab so that FD interest does not unexpectedly push you into a higher tax liability.
Conclusion
Fixed Deposits feel simple and safe, but it is important to understand the tax implications. If you ignore TDS, you might overestimate how much your money is really growing.
The good news is that just a little awareness goes a long way. Once you start calculating post-tax returns, you’ll make smarter choices about where to park your savings. Before opening your next FD, take a minute to see what you’ll actually earn.
