In a significant move to simplify tax compliance, the Income Tax Department has introduced Form 121, replacing the widely used Form 15G and Form 15H, effective from April 1, 2026

This update aims to remove confusion and streamline TDS declaration by introducing a single unified form making compliance easier for both taxpayers and professionals.

What is Form 121?

Form 121 is a self-declaration form that allows eligible taxpayers to request non-deduction of Tax Deducted at Source (TDS) when their total income is below the taxable limit.

✅ It replaces:

• Form 15G (earlier used by individuals below 60 years)
• Form 15H (earlier used by senior citizens)

👉 Now, a single form applies to all eligible taxpayers, regardless of age.

Why Was Form 121 Introduced?

Previously, taxpayers had to choose between Form 15G and Form 15H, which often led to confusion and filing errors.

Form 121 resolves this by:

1. Introducing a single standardized declaration form
2. Reducing filing mistakes and duplication
3. Making compliance faster and simpler
4. Improving clarity for taxpayers and financial professionals

Who Can File Form 121?

You are eligible to submit Form 121 if:

• You are a resident taxpayer
• Your total income is below the taxable limit
• Your total tax liability is NIL

Eligible categories include:

• Individuals (including senior citizens)
• Hindu Undivided Families (HUFs)
• Certain eligible entities

Who Cannot File Form 121?

Form 121 cannot be filed by:

• Non-Resident Indians (NRIs)
• Individuals with taxable income and tax liability
• Companies and partnership firm

Income Covered Under Form 121

This declaration helps avoid TDS on:

• Fixed deposit (FD) interest
• Savings account interest
• Post office deposits
• Dividends
• Mutual fund income
• Rental income
• Pension and PF withdrawals
• Insurance-related income

Why This Update is Important

🔹 1. Avoid Unnecessary TDS Deduction

Without submitting Form 121, banks may deduct TDS even if your income is not taxable.

👉 This leads to delayed refunds and extra compliance effort.

🔹 2. Better Cash Flow

By submitting the form:

• You receive full income without deduction
• No need to wait for refunds later

🔹 3. Simplified Compliance

Earlier confusion:

• "Should I submit Form 15G or 15H?”

Now:

• Only Form 121 is required
