Taxation of Cumulative Fixed Deposits (FDs)

 

Taxation of Cumulative Fixed Deposits (FDs)

If a person invests in a cumulative fixed deposit where the interest is reinvested every year and the entire amount is redeemed after 3 years, the cumulative interest and tax treatment work as follows:

  • Tax is Calculated on an Accrual Basis: Even though the interest is not physically received until maturity, the interest earned each financial year is considered taxable income for that year.

  • Annual Tax Reporting is Mandatory: The accrued interest must be reported every year in the Income Tax Return (ITR) under the head “Income from Other Sources.”

  • Taxed According to Your Income Tax Slab: The interest earned during each year is added to your total income and taxed at your applicable slab rate for that year.

  • Compounding Increases Taxable Interest Each Year: Since interest is reinvested, subsequent years generate interest on both the original principal and previously earned interest. As a result, the taxable interest amount gradually increases each year.

  • Avoids a Large Tax Burden at Maturity: Reporting interest annually prevents a situation where several years of accumulated interest are taxed together in the final year, potentially pushing the taxpayer into a higher tax bracket.

  • Annual TDS Monitoring by Banks: Banks track accrued interest on cumulative FDs and deduct TDS at the end of each financial year if the interest credited during that year exceeds the prescribed threshold limits.

  • Effect of TDS on Compounding: When TDS is deducted, the tax amount is reduced from the accrued interest balance. Consequently, the amount available for future compounding becomes slightly lower.

  • TDS Credit Can Be Claimed: Any TDS deducted by the bank is reflected in Form 26AS and the Annual Information Statement (AIS). The taxpayer can claim this amount as a tax credit while filing the ITR.

  • Avoiding TDS Through Form 15G/15H (where eligible): If the individual's total taxable income is expected to remain below the taxable limit, the appropriate declaration form may be submitted at the beginning of the financial year to avoid TDS deduction.

  • No Additional Tax at Maturity: When the FD matures, the payout consists of the principal and accumulated interest. Since the interest has already been taxed on an annual accrual basis, the maturity amount itself does not attract any additional taxation.


Example 1: ₹1,00,000 Invested for 16 Months

  • Principal Amount: ₹1,00,000
  • Interest Rate Assumed: 6.25% per annum
  • Tenure: 16 months
  • Compounding Method: Quarterly
  • Total Interest Earned: ₹8,603
  • Maturity Value: ₹1,08,603

Tax Treatment

  • The interest income of ₹8,603 is taxable under “Income from Other Sources.”
  • Since the interest earned is below the standard annual TDS threshold of ₹40,000, the bank is unlikely to deduct TDS if this is the depositor’s only FD with the bank.
  • Tax liability, if any, depends on the investor’s income tax slab.

Example 2: ₹1,00,000 Invested for 5 Years

  • Principal Amount: ₹1,00,000
  • Interest Rate Assumed: 6.05% per annum
  • Tenure: 5 years
  • Compounding Method: Quarterly
  • Total Interest Earned Over 5 Years: ₹35,015
  • Maturity Value: ₹1,35,015

Year-Wise Accrued Interest

  • Year 1: Approximately ₹6,189
  • Year 2: Approximately ₹6,572
  • Year 3: Approximately ₹6,979
  • Year 4: Approximately ₹7,411
  • Year 5: Approximately ₹7,864

Tax Treatment

  • The accrued interest for each year should be declared separately in the ITR for that respective financial year.
  • The full cumulative interest of ₹35,015 should not be reported only in the fifth year.
  • Since annual interest remains between approximately ₹6,000 and ₹8,000, it is below the standard ₹40,000 TDS threshold.
  • No TDS is likely to be deducted unless the depositor’s combined interest income from all deposits with the same bank exceeds the applicable threshold.

Key Takeaway

A cumulative FD does not defer taxation until maturity. Interest is taxable every year on an accrual basis, even though the cash is received only at the end of the tenure. Proper annual reporting ensures compliance, prevents double taxation, and avoids a large tax liability in the maturity year.
