Form 121 is a declaration used by eligible taxpayers to request non-deduction of TDS on specified income when their estimated tax liability for the relevant tax year is nil. For bond investors, the form can be relevant when interest income is otherwise subject to tax deduction at source. Form 121 replaces the earlier Forms 15G and 15H under the new tax framework applicable from the relevant transition period. This guide explains who can submit Form 121, when it should be submitted, how it works, and where investors can verify the latest requirements.
What is Form 121?
Form 121 is a statutory declaration under the Income-tax Rules, 2026.
Through this declaration, an eligible taxpayer informs the payer or deductor that their estimated tax liability for the relevant tax year is nil. Based on the declaration and applicable conditions, the payer may not deduct TDS on specified payments.
The form serves a practical purpose. It can help eligible taxpayers avoid TDS being deducted from qualifying income when they have no tax liability for the relevant year.
Form 121 replaces the earlier Forms 15G and 15H under the new income-tax framework. The earlier forms applied to different taxpayer categories, while Form 121 provides a unified declaration mechanism.
TDS on Bonds: Why is Form 121 Important for Bond Investors?
Bond investors may receive interest income from their investments.
Where applicable, TDS may be deducted by the payer when interest is credited or paid. If an eligible investor expects their total tax liability to be nil, Form 121 may allow the payer to avoid deducting TDS on specified income, subject to applicable conditions.
This can help avoid a situation where tax is deducted first and the investor later has to claim a refund through the income-tax return process.
However, submitting Form 121 does not automatically eliminate tax liability. It is a declaration based on the taxpayer's estimated total income and applicable conditions.
Benefits of Filing Form 121
For an eligible taxpayer, submitting the form may:
- Help prevent unnecessary TDS deduction on specified income.
- Improve cash-flow management by avoiding tax deduction upfront.
- Reduce the need to claim a refund for tax that was not ultimately payable.
- Provide a formal declaration to the relevant payer or deductor.
The benefit depends on meeting the applicable eligibility conditions. Form 121 should not be treated as a general exemption from tax.
Who Can File Form 121?
Form 121 Eligibility Criteria
Eligibility depends on the conditions prescribed under the applicable income-tax law and rules.
The central requirement is that the taxpayer's estimated tax liability for the relevant tax year must be nil, subject to the applicable statutory conditions.
The taxpayer must also provide accurate information in the declaration.
The form is not intended for every bond investor. Eligibility depends on the taxpayer's income, tax liability, nature of the payment, and other applicable conditions.
When Should Form 121 Be Submitted?
The Income Tax Department advises that the declaration should be furnished to the deductor on time, ideally before the income is credited or paid and preferably at the beginning of the tax year.
Submitting it before the relevant payment can help the deductor consider the declaration before deducting TDS.
Form 121 Example
Suppose an eligible taxpayer expects their total tax liability for the relevant tax year to be nil.
The taxpayer is due to receive interest income from a bond. If the payment falls within the specified income covered by the applicable provisions, the taxpayer may submit Form 121 to the relevant deductor.
If the declaration is valid and accepted under the applicable rules, TDS may not be deducted on the specified payment.
The taxpayer must still report income correctly and comply with applicable income-tax requirements.
Form 121 Vs Form 15G Vs Form 15H
Form | Current position |
Form 15G | Earlier declaration used by eligible taxpayers, including individuals below the specified senior-citizen age threshold |
Form 15H | Earlier declaration used by eligible senior citizens |
Form 121 | Unified declaration under the new tax framework |
Form 121 replaces the earlier Forms 15G and 15H under the Income-tax Rules, 2026. The exact provisions and transition rules should be checked for the relevant tax year.

Conclusion
Form 121 is a statutory declaration that can help eligible taxpayers avoid TDS on specified income when their estimated tax liability is nil and the applicable conditions are satisfied. For bond investors, understanding the form can help clarify how interest income and TDS interact under the new tax framework. However, eligibility should be assessed carefully, and the latest official requirements should always be checked before submission. Investors should also remember that non-deduction of TDS does not automatically mean that the underlying income is exempt from tax.
