Comprehensive Guide: How to Calculate TDS on Interest Income with Examples

Tax Deducted at Source (TDS) on interest income is a crucial aspect of financial planning in India. Whether you earn interest from fixed deposits, recurring deposits, or other investment instruments, understanding how TDS is calculated can help you manage your taxes better and avoid surprises during tax filing season.

What is TDS on Interest Income?

TDS on interest income is the tax that banks and financial institutions deduct when they pay you interest on your deposits. According to Income Tax Department of India regulations, if the interest earned from all your deposits with a particular bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens), the bank is required to deduct TDS at the rate of 10%.

When is TDS Deducted on Interest?

When interest from all fixed deposits with a single bank exceeds ₹40,000 (₹50,000 for senior citizens) in a financial year
When interest is paid or credited to your account, whichever is earlier
For recurring deposits, TDS is deducted at the time of credit of interest to your account
Even if you don’t withdraw the interest, TDS is deducted when the interest is credited to your account

Current TDS Rates on Interest Income (2023-24)

Category	TDS Rate	Threshold Limit
General Public	10%	₹40,000 per financial year
Senior Citizens (60+ years)	10%	₹50,000 per financial year
If PAN not provided	20%	No threshold

How to Calculate TDS on Interest Income – Step by Step

Determine the Interest Earned:
First, calculate the total interest earned on your deposit. This depends on:
- Principal amount
- Interest rate
- Compounding frequency
- Deposit tenure
Check the Threshold Limit:
Verify if your total interest exceeds the threshold limit (₹40,000 for general public, ₹50,000 for senior citizens). If it doesn’t exceed, no TDS will be deducted.
Apply the TDS Rate:
If the interest exceeds the threshold, apply the TDS rate (typically 10%) to the total interest amount.
Calculate Net Interest Received:
Subtract the TDS amount from the total interest to get the net interest you’ll receive.
Add to Maturity Amount:
The principal amount plus the net interest gives you the maturity amount you’ll receive.

Practical Example of TDS Calculation

Let’s consider an example to understand this better:

Example Scenario:

Principal Amount: ₹5,00,000
Interest Rate: 7% per annum
Deposit Tenure: 5 years
Compounding: Annually
TDS Rate: 10%

Step 1: Calculate Total Interest

Using the compound interest formula: A = P(1 + r/n)^(nt)

Where:

A = Maturity amount
P = Principal (₹5,00,000)
r = Annual interest rate (7% or 0.07)
n = Number of times interest is compounded per year (1)
t = Time in years (5)

A = 500,000 × (1 + 0.07/1)^(1×5) = ₹701,275.50

Total Interest = A – P = ₹701,275.50 – ₹500,000 = ₹201,275.50

Step 2: Calculate TDS

Since ₹201,275.50 > ₹40,000 (threshold), TDS applies

TDS Amount = 10% of ₹201,275.50 = ₹20,127.55

Step 3: Calculate Net Amount Received

Net Interest = Total Interest – TDS = ₹201,275.50 – ₹20,127.55 = ₹181,147.95

Maturity Amount = Principal + Net Interest = ₹500,000 + ₹181,147.95 = ₹681,147.95

How to Avoid TDS on Interest Income

While TDS is mandatory when your interest income exceeds the threshold, there are legal ways to minimize or avoid TDS deduction:

Submit Form 15G/15H:
If your total income is below the taxable limit, you can submit Form 15G (for general public) or Form 15H (for senior citizens) to the bank to avoid TDS deduction. These forms declare that your total income is below the taxable threshold.
Spread Deposits Across Multiple Banks:
By distributing your deposits across different banks, you can ensure that the interest from each bank stays below the TDS threshold. For example, instead of keeping ₹10 lakhs in one bank, you could keep ₹5 lakhs each in two different banks.
Invest in Tax-Saving Instruments:
Consider instruments like Public Provident Fund (PPF), National Savings Certificate (NSC), or tax-free bonds where interest is either tax-free or tax-deductible under Section 80C.
Opt for Cumulative Deposits:
In cumulative deposits, interest is reinvested and paid at maturity. While TDS is still applicable, this might help in better tax planning as you receive the amount in a single financial year.

Important Points to Remember About TDS on Interest

TDS is deducted on the total interest earned from all deposits with a particular bank, not per deposit.
Even if TDS is deducted, you need to declare the total interest earned (before TDS) in your income tax return.
You can claim credit for the TDS deducted when filing your income tax return.
If your total income is below the taxable limit but TDS was deducted, you can claim a refund by filing your income tax return.
For NRI accounts, TDS is deducted at 30% (plus applicable surcharge and cess) regardless of the interest amount.

How to Claim TDS Credit in Income Tax Return

When you file your income tax return, you can claim credit for the TDS that has been deducted from your interest income. Here’s how:

Check Form 26AS:
Form 26AS is your consolidated tax statement that shows all the TDS deducted on your behalf. You can access it through the Income Tax Department portal. Verify that the TDS deducted by your bank is reflected here.
Report Income in ITR:
In your income tax return (ITR), report the total interest income (before TDS) under the head “Income from Other Sources”.
Claim TDS Credit:
In the TDS schedule of your ITR form, enter the details of TDS deducted as per Form 26AS. The system will automatically calculate your tax liability after giving credit for the TDS already deducted.
Verify and Submit:
After filling all details, verify your return and submit it. Any excess TDS deducted will be refunded to you by the Income Tax Department.

Frequently Asked Questions About TDS on Interest

Is TDS deducted on interest from savings bank accounts?

No, TDS is not deducted on interest earned from savings bank accounts. However, the interest income is still taxable and must be declared in your income tax return if it exceeds ₹10,000 in a financial year (as per Section 80TTA).

What happens if I don’t provide my PAN to the bank?

If you don’t provide your PAN to the bank, TDS will be deducted at the higher rate of 20% instead of the normal 10%. This is as per Section 206AA of the Income Tax Act.

Can I get a refund if TDS was deducted but my income is below taxable limit?

Yes, you can claim a refund of the TDS deducted by filing your income tax return. The Income Tax Department will process your return and refund the excess TDS after verifying that your total income is indeed below the taxable limit.

Is TDS deducted on reinvested interest in cumulative deposits?

Yes, TDS is deducted on the interest even if it’s reinvested in cumulative deposits. The bank calculates the interest annually (or as per the compounding frequency) and deducts TDS if the total interest exceeds the threshold limit.

Expert Tips for Managing TDS on Interest Income

Plan Your Deposits:
Time your fixed deposits such that the interest doesn’t cross the threshold in a single financial year. For example, you could make deposits in March so that most of the interest is credited in the next financial year.
Use Joint Accounts Wisely:
If you have joint accounts, the interest is typically credited to the first holder. You can split large deposits between different family members to stay below the TDS threshold.
Monitor Your Interest Income:
Keep track of your interest income across all banks. Many people have multiple accounts and lose track of their total interest income, leading to unexpected TDS deductions.
Consider Tax-Free Options:
For long-term investments, consider tax-free instruments like PPF or tax-free bonds where you don’t have to worry about TDS deductions.
File Your Returns:
Even if your income is below the taxable limit but TDS was deducted, make sure to file your income tax return to claim the refund.

Recent Changes in TDS Rules (2023-24)

The Finance Act 2023 introduced some changes to TDS provisions that affect interest income:

Increased Threshold for Senior Citizens:
The threshold limit for senior citizens was increased from ₹50,000 to ₹50,000 (no change from previous year), but the government has been considering further increases to provide relief to senior citizens who rely on interest income.
TDS on Digital Transactions:
While not directly related to interest income, new TDS rules were introduced for digital transactions, showing the government’s focus on broadening the tax base through TDS mechanisms.
Enhanced Reporting Requirements:
Banks are now required to provide more detailed information about interest payments and TDS deductions to the Income Tax Department, making it easier for the department to track interest income across different banks.

For the most updated information on TDS rules, always refer to the official Income Tax Department website or consult with a qualified tax professional.

Case Study: TDS Calculation for Multiple Fixed Deposits

Let’s examine a more complex scenario where an individual has multiple fixed deposits with the same bank:

Scenario: Mr. Sharma has three fixed deposits with ABC Bank:

FD 1: ₹3,00,000 at 6.5% for 3 years
FD 2: ₹2,00,000 at 7% for 5 years
FD 3: ₹1,50,000 at 6.8% for 2 years

Interest Calculation (Annual Compounding):

FD 1: ₹3,00,000 × 6.5% = ₹19,500 per year
FD 2: ₹2,00,000 × 7% = ₹14,000 per year
FD 3: ₹1,50,000 × 6.8% = ₹10,200 per year

Total Annual Interest: ₹19,500 + ₹14,000 + ₹10,200 = ₹43,700

TDS Applicability:

Since ₹43,700 > ₹40,000 (threshold), TDS will be deducted at 10% on the total interest.

TDS Amount: 10% of ₹43,700 = ₹4,370

Key Learning: The bank considers the aggregate interest from all deposits with them, not individual deposits. Even though each FD’s interest is below ₹40,000, the total exceeds the threshold, making TDS applicable.
