How FD Interest is Taxed in India — TDS Rules Explained (2026)

The Part FD Investors Often Overlook

Fixed Deposits are marketed on their interest rate, but the number on the brochure isn't what lands in your account. Every rupee of FD interest is taxable, and for many investors, banks deduct tax at source before you even see it. Understanding how this works — and how to avoid over-payment or under-payment — matters as much as choosing the right FD in the first place.

How FD Interest Gets Taxed

FD interest is added to your total income and taxed at your applicable income tax slab rate — there's no special lower rate for it, unlike some other investments. This means a person in the 30% tax bracket effectively keeps far less of their FD interest than someone in the 5% bracket, even on the identical deposit.

Understanding TDS on FD Interest

Banks are required to deduct TDS (Tax Deducted at Source) on FD interest once it crosses a threshold in a financial year — ₹40,000 for regular individuals, and ₹50,000 for senior citizens. Some key points on how this works:

• TDS is deducted at 10% if you've submitted your PAN, or 20% if you haven't
• TDS is deducted even if the interest hasn't been paid out yet — banks calculate it on accrued interest each year, not just at maturity
• TDS deducted is not the final tax — it's an advance payment against your total tax liability, adjusted when you file your ITR

How to Avoid Unnecessary TDS

If your total income is below the taxable limit, you can avoid TDS deduction altogether by submitting Form 15G (for individuals below 60) or Form 15H (for senior citizens) to your bank at the start of the financial year. This is a declaration that your income doesn't require tax deduction — but submitting it when you actually do owe tax is a compliance mistake, not a way to avoid tax legally.

What If TDS Was Deducted But You Don't Owe Tax?

This happens often — someone below the taxable income threshold still has TDS deducted because they forgot to submit Form 15G/15H, or their total FD interest across multiple banks pushed them over the threshold at just one bank. In this case, the TDS isn't lost — you claim it back as a refund when you file your Income Tax Return.

Multiple FDs, Multiple Banks: A Common Trap

TDS thresholds apply per bank, not per person. If you hold FDs worth ₹35,000 interest at three different banks, none of them may deduct TDS individually — but your total taxable interest is ₹1,05,000, and you're still liable to pay tax on the full amount at your slab rate when filing your return, even though no TDS was deducted anywhere.

Calculate Your Actual Post-Tax Return

Since the headline FD rate isn't what you keep, it helps to see the real number. Use our FD Calculator to project your maturity value, then apply your tax slab to estimate what you'll actually take home after tax.

Common Mistakes

1. Assuming TDS is the total tax owed. If you're in a higher tax bracket than the 10% TDS rate, you owe additional tax at filing time.

2. Forgetting FD interest across multiple banks adds up. Each bank tracks its own threshold — you're responsible for tracking your total.

3. Submitting Form 15G/15H incorrectly. These forms are for people who genuinely don't owe tax; submitting them when you do owe tax can lead to penalties at assessment.

Key Takeaway: FD interest is fully taxable at your slab rate, and TDS is just an advance deduction, not the final bill — track your total interest across all banks and reconcile it at ITR filing time.
