The Hidden Truth About FD Returns

When a bank advertises a 7% Fixed Deposit (FD) interest rate, that is the pre-tax (gross) rate. The actual return you take home can be significantly lower depending on the income tax bracket you fall under.

Unlike Equity Mutual Funds (which enjoy a lower 12.5% LTCG tax rate) or PPF (which is completely tax-free), FD interest is fully taxable. It is added to your total income for the year under the head "Income from Other Sources" and taxed at your marginal slab rate (which can be as high as 30%).

TDS vs Actual Tax Liability

There is a lot of confusion regarding TDS (Tax Deducted at Source) on Fixed Deposits.

Special Relief for Senior Citizens (Section 80TTB)

To provide relief to retirees who rely on interest income, the Income Tax Act provides Section 80TTB exclusively for senior citizens (aged 60 and above).

Under 80TTB, a senior citizen can claim a deduction of up to ₹50,000 per financial year on interest earned from all bank deposits (including both Fixed Deposits and Savings Accounts). This means the first ₹50,000 of interest earned every year is completely tax-free, and tax is only applied to the interest earned above this amount.

*Note: This calculator assumes standard quarterly compounding for the FD (which is standard for Indian banks) and assumes the FD interest is taxed at maturity or accrued annually without cess/surcharge complexities for simplicity.*

Frequently Asked Questions

Is Fixed Deposit (FD) interest taxable?
Yes, the interest earned on Fixed Deposits is fully taxable. It is added to your total income under the head 'Income from Other Sources' and taxed according to your applicable income tax slab rate.
Does the bank deduct TDS on FD interest?
Yes, banks deduct TDS (Tax Deducted at Source) at 10% if your total FD interest across all branches of the bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens). If you have not submitted your PAN, TDS is deducted at 20%.
What is Form 15G and Form 15H?
Form 15G (for non-senior citizens) and Form 15H (for senior citizens) are self-declarations you can submit to the bank requesting them not to deduct TDS, provided your total income is below the basic exemption limit.
Can I claim deduction on FD interest under Section 80TTA?
No. Section 80TTA (which provides a deduction up to ₹10,000) is only for interest earned on Savings Bank accounts, not Fixed Deposits. Regular citizens cannot claim 80TTA for FD interest.
Do senior citizens get tax benefits on FD interest?
Yes, under Section 80TTB, senior citizens (aged 60 and above) can claim a tax deduction of up to ₹50,000 in a financial year on interest earned from deposits (including FDs and Savings accounts).
If the bank deducts 10% TDS, do I still need to pay more tax?
Yes, if you fall in the 20% or 30% tax slab. The bank only deducts 10% TDS. You must calculate your total tax liability, subtract the TDS already paid, and pay the remaining balance as advance tax or self-assessment tax.
What is Form 15G and Form 15H for FDs?
Form 15G (for individuals under 60) and Form 15H (for senior citizens) are self-declaration forms submitted to banks to prevent TDS deduction if your total annual income is below the taxable threshold.
How do I calculate my real post-tax FD return after inflation?
Subtract the annual inflation rate from your net post-tax FD interest rate. If your post-tax return is 4.9% and inflation is 6%, your real purchasing power growth is -1.1%.
