If you are a senior citizen earning interest from fixed deposits, a key tax rule has changed from April 2026. Form 15H has been replaced by Form 121, which simplifies how you declare income to avoid TDS and helps ensure steady cash flow in retirement.
Form 121 is a unified declaration for all individuals, removing the need for separate forms like 15G and 15H.
If you are a senior citizen earning interest income from fixed deposits or similar investments, a key tax rule has changed from April 2026. The government has replaced Form 15H with Form 121, introducing a simplified and more unified system to help you avoid Tax Deducted at Source (TDS) and manage your retirement cash flow more efficiently.
What has changed?
Until now, you may have used Form 15H to declare that your taxable income is below the exemption limit, ensuring that banks do not deduct TDS on your interest income. From April 2026, this process has been streamlined with Form 121, which replaces both Form 15H (for senior citizens) and Form 15G (for others).
This means you now have a single, unified declaration form applicable to all individuals, reducing confusion and improving ease of compliance.
What is Form 121 and how does it work?
Form 121 is designed to be more flexible and user-friendly. It allows you to declare income across multiple sources, including fixed deposits, post office schemes, bonds, and other interest-bearing instruments.
You can submit the form:
Online through bank portals
Offline via financial institutions
To successfully avoid TDS, you must:
Ensure your total taxable income is below the exemption limit
Submit the form before interest is credited
Provide accurate PAN and income details
Filing the form on time ensures that your full interest income is credited without deductions—an important factor for managing monthly expenses in retirement.
Introduction of UIN system
A key feature of the new system is the Unique Identification Number (UIN). This helps track your declarations, improve transparency, and reduce disputes or errors in TDS processing. It also enables better monitoring of submissions by tax authorities.
Why was Form 15H scrapped?
The government’s move is driven by three main factors:
Simplification: Replacing multiple forms with one reduces complexity
Removal of duplication: Form 15G and 15H served similar purposes
Digital push: Encourages online submissions and faster processing
Overall, Form 121 aligns with the broader goal of making tax compliance simpler and more efficient.
How does this impact your retirement income
For many senior citizens, interest income is a primary source of monthly cash flow. Even small TDS deductions can disrupt budgeting and create liquidity issues.
By submitting Form 121 correctly and on time, you can:
Avoid unnecessary tax deductions
Maintain steady monthly income
Reduce dependency on refunds later
For example, a retiree earning ₹60,000 annually from fixed deposits can receive the full amount without deduction if Form 121 is filed properly.
Key mistakes to avoid
To fully benefit from the new system, you should avoid common errors:
Late submission: File at the start of the financial year
Single submission assumption: Submit separately to each bank or payer
Inactive PAN: Ensure PAN is linked with Aadhaar
Incorrect income declaration: Mismatch may trigger scrutiny
Ignoring ITR reporting: Always reflect income in your tax return
What seniors should note
Form 121 marks a significant shift in how you manage TDS on interest income. While the process is now simpler and more digital, timely and accurate submission remains critical.
For you, the focus should be clear—file early, declare correctly, and ensure eligibility. Done right, this new system can help you protect your income, avoid unnecessary deductions, and plan your retirement finances with greater certainty.
