Have you ever noticed a chunk of your hard-earned fixed deposit (FD) interest missing because the bank deducted tax? This deduction is called TDS (Tax Deducted at Source). For many individuals, especially retirees, homemakers, and low-income earners, this deduction happens even when their total annual income doesn’t fall into the taxable bracket.
To prevent this unnecessary deduction, the Income Tax Department allows eligible citizens to submit a self-declaration form.
Historically, these were known as Form 15G and Form 15H. However, following the latest legal updates, a major compliance shift has taken place. This comprehensive guide covers everything you need to know about saving your interest income from TDS, introducing the brand-new framework.
The Big Update: Introduction of Form 121
If you are planning your tax strategy, there is a crucial regulatory change you must know about:
What Most Websites Don’t Tell You: Under the updated Income Tax Rules, the traditional Form 15G and Form 15H have been officially merged into a single, unified declaration known as Form 121.
If you want to prevent TDS on your interest income, you no longer need to figure out whether you fall under 15G or 15H. Instead, you will submit the unified Form 121.
Quick Comparison: Form 15G vs. Form 15H vs. Form 121
| Feature | Form 15G | Form 15H | Form 121 (New Unified Form) |
| Target Audience | Resident individuals below 60 years & HUFs | Resident Senior Citizens (Aged 60 or above) | All eligible Resident Taxpayers |
| Age Criteria | Below 60 years | 60 years and above | No separate age forms; unified criteria |
| Tax Liability | Nil | Nil | Nil |
| Status | Replaced | Replaced | Active & Mandatory |
Who is Eligible to Submit the TDS Declaration?
You cannot just file Form 121 (or the erstwhile 15G/15H) to escape tax if you have a high income. This form is strictly a self-declaration that your total income is tax-free.
Eligibility Criteria:
- Resident Status: You must be a Resident Indian individual. Non-Resident Indians (NRIs) are strictly ineligible to submit these forms.
- Nil Tax Liability: Your calculated net income tax for the financial year must be zero.
- Basic Exemption Limit: Your total income must be below the basic tax exemption slab. Under the current tax regimes, this cap stands at:
- Old Tax Regime: Total income up to ₹2.5 Lakhs.
- New Tax Regime: Total income up to ₹4 Lakhs.
Where Can You Use Form 121/15G/15H? (TDS Sections)
While banks are the most common place to submit these forms, they can save you from TDS across a wide variety of financial instruments:
| Section | Nature of Payment | TDS Threshold Limit (Per FY) |
| 194A | Interest on Bank FDs, Recurring Deposits (RDs), Post Office | ₹50,000 (₹1,000,000 for Senior Citizens) |
| 192A | Premature EPF Withdrawal (before 5 years of service) | ₹50,000 |
| 194 | Dividend Income from Stocks/Shares | ₹10,000 |
| 193 | Interest on Corporate Securities, Debentures, Govt Bonds | ₹5,000 to ₹10,000 |
| 194K | Income/Dividends from Mutual Fund Units | ₹10,000 |
| 194-I | Rental Income (Land, Buildings, Plant & Machinery) | ₹50,000 per month / ₹6 Lakhs per annum |
| 194DA | Maturity proceeds of a Life Insurance Policy (LIC) | ₹1,000,000 |
Real-Life Scenarios: Understanding the Math
Scenario 1: Non-Senior Citizen (Old Form 15G / New Form 121)
Ananya is a 32-year-old freelance content writer based in Bangalore. She has no fixed salary but earned ₹2,20,000 entirely from interest on a legacy fixed deposit. Because her total income is under the ₹2,50,000 threshold, her net tax liability is nil. However, without a declaration, the bank will deduct 10% TDS (₹22,000) under Section 194A. By submitting the declaration form in April, she ensures the bank credits her full interest without deductions.
Scenario 2: Senior Citizen (Old Form 15H / New Form 121)
Mr. Patel, aged 67, receives ₹3,20,000 as annual interest from senior citizen fixed deposits and ₹40,000 from equity mutual fund dividends. After deploying deductions under Section 80C, his net taxable income falls below the exemption limit. He submits his declaration form to both his bank and his mutual fund house at the start of the financial year to receive his full earnings smoothly.
Common Mistakes to Avoid
- The Clubbing of Income Trap: Do not submit a declaration form for a fixed deposit opened in the name of a non-earning spouse or a minor child. Under Indian tax laws, this interest is automatically clubbed with the income of the primary breadwinner.
- Missing PAN: Your Permanent Account Number (PAN) must be linked and valid. Failing to provide a correct PAN defaults the TDS deduction rate to a punishing 20% instead of the standard 10%.
- Submitting Late: These forms must ideally be submitted in April at the beginning of the financial year. If you submit it in October, the bank will likely have already deducted TDS for the first two quarters.
What to Do If You Forgot to Submit the Form?
If you realized late that your bank has already deducted TDS, do not panic. You have two recovery paths:
- Submit the Form Immediately: While you cannot get back what the bank has already deducted, submitting Form 121 immediately will protect your interest from being taxed in the remaining quarters of the financial year.
- File an Income Tax Return (ITR): The bank cannot refund your deducted TDS because they deposit that money into the government’s account every quarter. The only way to claim this money back is by filing your ITR at the end of the financial year. The Income Tax Department will issue a direct refund to your verified bank account.
Warning: Penalty for Filing a False Declaration
Filing Form 121/15G/15H when you actually have taxable income is a criminal offense. If you knowingly submit a false declaration to evade tax, you can be prosecuted under Section 277 of the Income Tax Act:
- If the tax evaded exceeds ₹25 Lakhs, it carries a penalty of rigorous imprisonment from 6 months up to 7 years along with a fine.
- For smaller amounts, the penalty involves imprisonment ranging from 3 months to 2 years along with a fine.
How to Submit the Form Online
- Log in to your bank’s official internet banking portal.
- Navigate to the ‘Tax Services’ or ‘TDS Declarations’ tab.
- Select the option to submit Form 121 (or 15G/15H based on your bank’s current interface layout).
- Select your active account numbers, verify your pre-filled PAN card details, enter your estimated annual income, and authenticate the form using an OTP sent to your registered mobile number.
Conclusion
Maximizing your savings requires zeroing out preventable leakages like unwanted TDS. By understanding the shift toward the unified Form 121 and filing your declarations at the very beginning of the financial year, you can secure complete liquidity over your interest and dividend payments.
