| Overview: Fixed deposits remain India’s favourite investment, but taxation on interest can significantly reduce returns. This guide reveals practical strategies to save tax on FD interest, including TDS exemptions, smart account splitting, tax-saver FDs, and special benefits for senior citizens to maximise your post-tax earnings. |
Understanding FD Interest Taxation in India
Fixed deposits continue to be the backbone of Indian household savings, with over 60% of families relying on them for secure returns. However, many investors overlook the tax implications that can substantially impact their earnings. When you earn interest on your FD, it’s treated as “Income from Other Sources” and added to your total annual income, taxed according to your applicable slab rate.
The taxation landscape for FD interest involves several key elements. Banks deduct TDS (Tax Deducted at Source) when your annual interest from a single bank exceeds ₹50,000. For senior citizens, this threshold increases to ₹1,00,000 per bank. Understanding how to save tax on FD interest requires grasping these fundamental rules and leveraging available exemptions effectively.
TDS Rules and Exemption Strategies
The government sets specific limits for TDS deduction on FD interest. If your annual interest earnings from one bank cross ₹50,000, the bank automatically deducts 10% TDS (provided you’ve submitted your PAN details). Without PAN, the TDS rate jumps to 20%. Senior citizens enjoy a higher exemption limit of ₹1,00,000 per bank.
Here’s a practical example: Suppose Mr Gupta has FDs across three banks earning ₹45,000, ₹55,000, and ₹35,000, respectively. Only the second bank will deduct TDS of ₹5,500, as it’s the only one exceeding the threshold.
Using Form 15G and 15H Effectively
One of the most effective ways to save tax on FD interest is through Form 15G (for individuals below 60) and Form 15H (for senior citizens). These forms prevent TDS deduction when your total income falls below the taxable threshold.
Form 15G/15H Requirements:
- Submit at the beginning of each financial year.
- Total income must be below taxable limits.
- Cannot be used if you expect to pay tax during the year.
- Must be submitted to each bank separately.
| Pro Tip: Submit these forms by April to ensure no TDS is deducted throughout the year. If submitted later, you’ll need to claim refunds during ITR filing. |
Smart Account Management for Tax Optimisation
Splitting your FDs across multiple banks can significantly help you save tax on FD interest by keeping earnings below TDS thresholds at each institution. This strategy works particularly well for investors with substantial FD portfolios.
Consider this scenario: Mrs Sharma has ₹20 lakh to invest. Instead of placing it all in one bank earning ₹1.4 lakh interest annually, she splits it across four banks, earning ₹35,000 each. Result? No TDS deduction at any bank, improving her cash flow.
| Strategy | Single Bank | Multiple Banks |
| Principal Amount | ₹20,00,000 | ₹5,00,000 each |
| Annual Interest (7%) | ₹1,40,000 | ₹35,000 each |
| TDS Deducted | ₹14,000 | Nil |
| Cash Flow Advantage | Lower | Higher |
Understanding CBS vs Non-CBS Banks
Banks with Core Banking Solutions (CBS) apply TDS thresholds across all branches, while non-CBS banks apply limits per branch. This distinction can be crucial for your FD planning strategy.
Tax-Saver FDs: Dual Benefits with Limitations
Tax-saver FDs offer a unique opportunity to save tax on FD interest through principal deduction while earning returns. These 5-year lock-in deposits allow deductions up to ₹1.5 lakh under Section 80C, reducing your taxable income.
Tax-Saver FD Calculation Example
Let’s examine how tax-saver FDs work:
- Investment: ₹1,50,000 in tax-saver FD
- Tax Bracket: 30%
- Tax Saved on Principal: ₹45,000 (₹1,50,000 × 30%)
- Annual Interest (assuming 7%): ₹10,500
- Tax on Interest: ₹3,150 (₹10,500 × 30%)
- Net Tax Benefit: ₹41,850
Special Provisions for Senior Citizens
Senior citizens enjoy additional advantages when learning how to save tax on FD interest. Beyond the higher TDS exemption limit, they can claim deductions under Section 80TTB.
Section 80TTB Benefits
Senior citizens can claim up to a ₹50,000 annual deduction on interest from:
- Fixed deposits
- Savings accounts
- Recurring deposits
- Post office deposits

Advanced Tax Planning Strategies
Strategic timing of FD maturity can help manage your annual tax liability. If you’re expecting a higher income in the current year, consider extending FD maturity to the following year when your income might be lower.
Comparing FD with Other Tax-Efficient Instruments
While learning how to save tax on FD interest, consider alternatives that offer better tax treatment:
| Instrument | Tax on Principal | Tax on Returns | Lock-in Period |
| Regular FD | No deduction | Fully taxable | Flexible |
| Tax-Saver FD | ₹1.5L deduction | Fully taxable | 5 years |
| PPF | ₹1.5L deduction | Tax-free | 15 years |
| ELSS | ₹1.5L deduction | Tax-free (conditions apply) | 3 years |
Loan Against FD Strategy
Instead of breaking FDs prematurely, consider taking a loan against your fixed deposit. This preserves your FD’s tax-saving benefits while providing liquidity. Interest paid on such loans may qualify for deductions under specific circumstances.
Maximising Your FD Returns Through Smart Planning
Understanding FD interest rates across different tenures helps optimise both returns and tax implications. Use an FD calculator to model various scenarios and their tax impact before making investment decisions.
The key to successful FD tax planning lies in understanding the complete picture. While FDs offer security and guaranteed returns, their tax treatment requires careful planning. Consider diversifying across tax-efficient instruments while maintaining the stability that FDs provide.
Key Takeaways for FD Tax Optimisation
Successfully learning how to save tax on FD interest requires a multi-pronged approach combining strategic planning, proper documentation, and timing. Start by submitting Form 15G or 15H if eligible, distribute your FDs across multiple banks to stay below TDS thresholds, and consider tax-saver FDs for dual benefits.
Senior citizens should maximise Section 80TTB deductions alongside higher TDS exemption limits. Remember that while these strategies help optimise your tax liability, maintaining proper documentation for your FDs remains crucial for smooth processing.
