Form 121: India’s New TDS Declaration Form (Replaces Forms 15G & 15H)

From April 1, 2026, Form 121 is the only TDS self-declaration form you need to prevent tax deduction at source on interest, dividends, and other income — provided your total tax liability for the year is nil. It replaces both Form 15G (for individuals under 60) and Form 15H (for senior citizens) under the new Income Tax Act 2025.

If you submitted Form 15G or 15H in previous years, you must now use Form 121. This guide explains exactly who can file it, what income it covers, how to submit it, and the mistakes that cause TDS to get deducted even after submission.

Why the Government Replaced 15G and 15H

The old system had two separate forms — 15G for taxpayers under 60 and 15H for those 60 and above. This created unnecessary complexity: a 59-year-old would file 15G one year and switch to 15H the next, with different eligibility rules, different conditions, and plenty of room for confusion.

Form 121 consolidates both into one age-neutral declaration. The core eligibility condition remains the same — your estimated tax liability for the financial year must be nil — but now a single form applies regardless of your age.

Who Can File Form 121?

You are eligible to submit Form 121 if you meet all three of the following conditions:

  1. You are a resident individual or HUF (Hindu Undivided Family)
  2. Your PAN is valid and operative
  3. Your estimated total tax liability for the financial year is nil

Not eligible:

  • Companies and firms (regardless of income level)
  • Non-resident Indians (NRIs)
  • Anyone whose total income, after deductions, still attracts tax
Common misconception: You don’t need zero income — you need zero tax liability. If your total income falls within the basic exemption limit, or your deductions bring your taxable income to nil, you qualify. For FY 2026–27, the basic exemption limit under the new tax regime is Rs. 4 lakh.

Income Types Covered Under Form 121

Form 121 can be used to prevent TDS on the following income categories:

Income Type TDS Deducted By
Interest on bank fixed depositsBanks, post offices, co-operative societies
Interest on savings accounts (above threshold)Banks
Dividends from shares and mutual fundsCompanies, AMCs
Income from mutual fund unitsAMCs
PF withdrawals (below 5 years of service)EPFO, private PF trusts
Life insurance payoutsInsurance companies
Rent (above threshold)Payers of rent
Insurance commissionInsurance companies
Pension (certain categories)Pension disbursing entities
You must submit Form 121 separately to each payer. If your FD interest comes from three different banks, you file three separate declarations.

Form 121 vs Form 15G vs Form 15H — Key Differences

Feature Form 15G (old) Form 15H (old) Form 121 (new)
Applicable from Pre-April 2026 Pre-April 2026 April 1, 2026 onwards
Who files it Individuals below 60 Individuals 60+ Any age + HUFs
Governing law Income Tax Act, 1961 Income Tax Act, 1961 Income Tax Act, 2025
Age restriction Yes (under 60 only) Yes (60+ only) None
HUFs covered Yes No Yes
Tax liability condition Must be nil Must be nil Must be nil
Important: If you filed 15G or 15H for FY 2025–26, you must use Form 121 from FY 2026–27 onward. The old forms are invalid from April 1, 2026 — institutions are required to reject them and deduct TDS.

How to Submit Form 121 — Step by Step

1

Check your eligibility

Estimate your total income for FY 2026–27 from all sources — salary, interest, dividends, rent, pension. Subtract applicable deductions. If the resulting taxable income carries zero tax liability, you can proceed.

2

Download the official form

Get the Form 121 PDF from the Income Tax Department at incometaxindia.gov.in. Do not use third-party PDFs — use only the official version to avoid rejection.

3

Fill Part A — Declarant Details

Enter your full name (exactly as on PAN card), PAN number, complete residential address, assessment year (2026–27), nature of income, estimated income amount, and total estimated income for the year.

For HUFs: Enter the HUF name in full — not the Karta’s individual name.

4

Fill Part B — Payer Details

Provide the payer’s name, address, and TAN. The payer institution completes Part B on their end after you submit.

5

Submit before income is credited

This is the most critical timing rule. Submit Form 121 before the income is paid or credited to your account. If you miss this window, TDS is already deducted and you will need to claim a refund when filing your ITR.

For FDs with monthly interest: submit in April, before the first interest credit of the financial year.

6

Submit separately to each payer

One form per payer, per financial year. Submit directly to each institution that pays you income — your bank, AMC, or insurance company.

  • Online: Log in to net banking → Forms/TDS section → submit Form 121 digitally (e-verification via Aadhaar OTP or net banking)
  • Offline: Download, fill, sign, and physically submit at your bank branch or the paying institution

Common Mistakes That Cause TDS to Get Deducted Anyway

1. Submitting after interest is credited

The single most common mistake. If your FD credits interest on April 5 and you submit Form 121 on April 10, TDS is already gone. Submit at the start of every financial year, before any income is credited.

2. Filing with only one bank when you have FDs in multiple banks

Each payer is independent. If you have deposits at SBI, HDFC, and a co-operative bank, you need three separate Form 121 submissions — one to each institution.

3. PAN errors

A single wrong character in your PAN invalidates the entire declaration. TDS will be deducted at 20% — the higher rate applicable when PAN is not correctly furnished. Double-check every character before submitting.

4. Underestimating total income

Include all income sources, not just the one you’re filing Form 121 for. If your actual income later crosses the taxable threshold, the declaration becomes incorrect and can attract penalties under the Income Tax Act.

5. Not resubmitting when deposits change

If you open a new FD or renew an existing one mid-year, you must submit Form 121 again to that institution. The form covers a specific financial year and specific income — it does not automatically cover new or renewed deposits.

6. Using old 15G/15H forms

From April 1, 2026, institutions are required to reject old forms and deduct TDS. Always use Form 121.

Frequently Asked Questions

Is submitting Form 121 mandatory?
No. It is optional. If you do not submit it and your income is taxable, TDS is correctly deducted. If your income is below the taxable limit but you do not file, TDS will still be deducted — you can then claim a refund when filing your ITR.
Can I submit Form 121 if I also have salary income?
Yes, provided your total estimated tax liability for the year is nil. Include your salary when estimating total income before deciding to file.
Do I need to file Form 121 with the Income Tax Department?
No. You submit it directly to the payer — your bank, AMC, or insurance company. The payer is required to report submissions to the department quarterly.
What happens if I file Form 121 but my income later exceeds the taxable limit?
You are responsible for the accuracy of the declaration. If your actual income results in a tax liability, you must pay the tax when filing your ITR. Filing a false declaration attracts prosecution under the Income Tax Act.
Can NRIs submit Form 121?
No. Form 121 is only for resident individuals and HUFs. NRIs must use separate TDS exemption mechanisms available to them under DTAA or other provisions.
Is there a deadline to submit Form 121?
No fixed deadline, but it must be submitted before income is credited or paid. The practical deadline for most fixed deposit holders is early April each financial year, before the first interest credit.
What if my bank doesn’t accept Form 121 online?
Submit the physical form at the branch and keep an acknowledgement copy. If the bank still deducts TDS despite a valid submission, escalate to the bank’s nodal officer and claim the refund via your ITR.
