Form 121, 15G, and 15H: Complete Guide to Save TDS on Interest Income
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: 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.
