What is Form 121? How It Works and How It Differs from Form 15G and 15H

With the new financial year in motion, tax rules have also seen an important update. The familiar Forms 15G and 15H are now being replaced by a single, streamlined document, Form 121 . This shift aims to make the process of avoiding TDS (Tax Deducted at Source) simpler and more efficient for taxpayers.

If your income falls below the taxable limit, understanding this new form is essential. Here’s a quick and clear breakdown.

What is Form 121 ?

Form 121 is a self-declaration form that allows individuals to confirm that their total annual income is below the taxable threshold. By submitting it, you request that no TDS be deducted from your earnings.

This rule comes under Section 393(6) of the Income Tax Act, 2025. It applies to incomes like bank interest, post office deposits, and other specified sources where TDS is usually deducted.

Who Can Submit Form 121?

Form 121 is designed for taxpayers who do not have any tax liability. Eligible categories include:

• Resident individuals
• Senior citizens
• Hindu Undivided Families (HUFs)
• Certain eligible entities with zero taxable income

However, not everyone can use this form. Companies, partnership firms, and Non-Resident Indians (NRIs) are not allowed to file Form 121.

When and Where to Submit It?

Timing matters when it comes to Form 121. Ideally, you should submit it:

• At the beginning of the financial year
• Before earning income like interest from banks or deposits

You can submit the form at:

• Banks
• Post offices
• Other financial institutions

Many banks now offer online submission through internet banking or mobile apps, making the process quick and hassle-free.

Documents You’ll Need

To fill out Form 121 correctly, keep these details ready:

• PAN card
• Bank account details
• Income and investment information
• Proof of age
• Estimated total income for the year
• Relevant financial year details

Having accurate information ensures smooth processing and avoids any issues later.

What Happens After Submission?

Once you submit Form 121, the concerned institution verifies your details. After successful verification:

• A Unique Identification Number (UIN) is generated
• Your declaration is recorded and shared with the Income Tax Department
• TDS is not deducted from your eligible income

This system also helps maintain proper records and prevents misuse.

Why This Change Matters

The introduction of Form 121 replaces multiple forms with one simplified option. It reduces confusion, saves time, and makes compliance easier, especially for individuals who rely on interest income and want to avoid unnecessary TDS deductions.

In short, if your income is below the taxable limit, submitting Form 121 at the right time can help you keep your earnings intact without extra paperwork.
