Form 15H Becomes Form 121 for Tax Year 2026-27
For Tax Year 2026–27, the no-TDS self-declaration corresponding to Form 15H is furnished in Form 121 under section 393(6).
It is available to a resident individual aged 60 or more only when estimated tax on total income is nil.
Legal or Computational Framework
Governing rule
The declaration does not make interest exempt and cannot be filed merely because one bank's interest is below a threshold. The payer must report the declaration under the new rules.
Correct calculation method
Estimate total income and final tax; confirm residence and age; include all interest/pension/other income; submit Form 121 to each payer; file a return if otherwise required.
Step-by-step workflow
- Estimate total income and final tax.
- confirm residence and age.
- include all interest/pension/other income.
- submit Form 121 to each payer.
- file a return if otherwise required.
Worked example
A senior has bank interest ₹6 lakh but deductions and rebate reduce final tax to nil. Form 121 can be considered. If final tax is ₹5,000, the declaration is invalid even if no single FD crosses a threshold.
The example is an illustration, not a substitute for the taxpayer's facts. A change in status, period, payment mode, document, city, asset, relationship or scheme can change the result.
Why generic pages get this wrong
Search pages often state a rate or limit without identifying the governing base. The calculation must distinguish gross receipt from taxable profit, tax from TDS, a deduction from an exemption, salary from business income, and an accounting entry from the tax treatment.
Decision matrix
| Decision point | Required treatment |
|---|---|
| Legal year | Use the Act, rules and notification effective for the income or transaction period |
| Taxpayer category | Confirm residence, age, entity, employee/business status and regime |
| Calculation base | Use the statutory definition rather than CTC, net bank receipt or accounting label |
| Ceiling or rate | Apply actual-amount, percentage, shared, lifetime and gross-income limits in sequence |
| Documentation | Link every input to an invoice, statement, contract, certificate or official record |
| Final output | Show tax, surcharge, cess, interest and TDS/TCS credits separately |

Finin2min Summary
In practice: Form 121 is not a below-threshold shortcut - a senior citizen with several small fixed deposits, none individually crossing the bank’s TDS threshold, still cannot use it unless the ESTIMATED FINAL TAX on total income (after all deductions and rebate) is genuinely nil. Aggregate every interest source before deciding, not just the amount at the bank where the form is being submitted.
Finin2min rule: establish eligibility, calculate transparently, and preserve an audit trail.
