You opened a Rs. 5 lakh FD at 7.5% for one year. You expect Rs. 37,500 in interest. Your bank statement shows Rs. 33,750 credited after TDS. You also have a large salary and are in the 30% bracket. Come tax filing time, you owe an additional Rs. 4,500 on top of what was already deducted.

That Rs. 37,500 in FD interest effectively earned you Rs. 26,250 after all taxes. Your real return was 5.25%, not 7.5%.

Here is how this works and what you can do about it.

How FD Interest Is Taxed

FD interest is added to your total income and taxed at your income slab rate. There is no special lower rate for FD interest - it is treated exactly like your salary or business income.

At the 30% slab (income above Rs. 10 lakh under old regime, or above Rs. 24 lakh under new regime), the effective FD return of 7.5% becomes:

7.5% x (1 - 0.30) x (1 - 0.04) = 7.5% x 0.688 = 5.16%

Inflation in India has averaged 5-6% in recent years. Your real return on a 7.5% FD in the 30% bracket may be zero or slightly negative after inflation.

TDS on FD: The Mechanics

Banks deduct TDS on FD interest when the cumulative FD interest in a financial year exceeds Rs. 40,000 per bank (Rs. 50,000 for senior citizens).

TDS rate: 10% (if PAN is submitted). 20% (if PAN is not submitted).

This is not the final tax - it is just an advance tax collection. The actual liability depends on your slab rate. At 30% slab, TDS of 10% means you owe an additional 20% (30% - 10%) when you file ITR.

Banks issue Form 16A for TDS deducted on FD interest. This certificate is essential for ITR filing. Always download it from TRACES (tracess.gov.in) or collect it from your bank.

The Form 15G and 15H Route (Legally Reduce TDS)

Form 15G: For individuals below 60 years. Submit to your bank if:

  • Your total income for the year is below the taxable threshold (Rs. 2.5 lakh under old regime, Rs. 3 lakh under new regime)
  • The total FD interest across all branches of that bank is below the taxable threshold

If you qualify, TDS will not be deducted. You still declare the interest income in ITR, but no advance deduction happens.

Form 15H: For senior citizens (60+). Submit if total income (including FD interest) remains below the tax-free limit after all exemptions.

Important: Submit 15G/15H at the start of every financial year. Banks reset TDS rules annually. A 15G submitted in April needs to be renewed next April.

False declaration on Form 15G/15H is a punishable offense - only submit if you actually qualify.

Senior Citizens: Section 80TTB Benefit

Senior citizens (60+) can deduct up to Rs. 50,000 per year from interest income under Section 80TTB. This covers interest from savings accounts, FDs, and RDs.

For a senior citizen in the 20% bracket with Rs. 1 lakh in annual FD interest:

  • Without 80TTB: Tax on Rs. 1 lakh at 20% = Rs. 20,000
  • With 80TTB: Tax on Rs. 50,000 at 20% = Rs. 10,000
  • Saving: Rs. 10,000 per year

Splitting FDs Across Family Members

If you have significant savings, placing FDs in the names of family members in lower tax brackets legally reduces the tax burden.

A spouse with no income of their own earning Rs. 2 lakh in FD interest pays zero tax (below the basic exemption limit). The same Rs. 2 lakh in your name at a 30% slab costs Rs. 62,400 in tax.

This is completely legal - just maintain genuine intent. The money must actually belong to the family member (gifted properly, not just for tax purposes). Gifts to spouse and adult children are often done through proper documentation.

Note: “Clubbing provisions” under Section 64 apply to minors - interest earned by a minor child from gifted money is clubbed with the parent’s income.

Debt Mutual Funds vs FDs: The Tax Change

A crucial change happened in April 2023: debt mutual funds no longer enjoy indexation benefits. Gains are now taxed at slab rate regardless of holding period. This makes debt MFs and FDs roughly equivalent on tax treatment.

However, liquid funds and arbitrage funds still have an edge for short-term money:

  • Arbitrage funds are classified as equity funds (65%+ in equity arbitrage)
  • STCG on equity: 20% (vs FD interest at your slab rate up to 30%)
  • For 30% bracket investors: arbitrage fund can save 10% in tax on short-term parking

For 3-year+ horizon, consider Senior Citizen Savings Scheme (SCSS) for senior citizens - 8.2% currently, returns are taxable but the rate is superior to most FDs.

What High-Bracket Investors Should Do

Action Tax Impact
Submit Form 15G/15H (if eligible) Avoid 10% TDS advance deduction
Split FDs across family members Leverage lower tax brackets
Use arbitrage funds for parking short-term cash 20% STCG vs 30% slab rate
Use PPF for debt allocation (7.1%, tax-free) Zero tax on interest
Claim 80TTB if senior citizen Up to Rs. 10,000 saving per year

Bottom Line

FD interest in the 30% tax bracket effectively yields 5.1-5.3% post-tax, which is barely ahead of inflation. TDS at 10% is just the first installment - you pay the balance at filing time. Submit Form 15G/15H if you qualify, split FDs across family members in lower brackets where genuinely appropriate, and consider that PPF at 7.1% tax-free is nearly always a better deal than FD at 7.5% taxable in the 20-30% bracket.
