What is Form 121?

Form 121 is a new tax declaration form introduced under Section 393(6) of the Income Tax Act, effective from April 1, 2026. It has been designed to replace Forms 15G and 15H, with the aim of simplifying the tax exemption declaration process for individuals with income below the taxable threshold. By consolidating the features of its predecessors, Form 121 ensures a more seamless compliance experience for taxpayers.

Why was form 121 introduced?

The introduction of Form 121 marks a significant step towards streamlining India’s tax ecosystem. By replacing Forms 15G and 15H, the government seeks to reduce redundancy and create a unified process for individuals to declare their non-taxable income and avoid Tax Deducted at Source (TDS) on interest earnings.

For taxpayers seeking to maximise their savings, Bajaj Finance Fixed Deposits offer an ideal solution. With competitive interest rates and no TDS deductions (when Form 121 is submitted), these fixed deposits align perfectly with the evolving tax framework, providing assured returns and financial stability.

Who can file Form 121?

Form 121 is designed for individuals whose total income falls below the taxable limit. The following groups can file this form:

  • Individuals below the age of 60 with income below the taxable threshold.
  • Senior citizens (aged 60 years or above) whose income is non-taxable.
  • Hindu Undivided Families (HUFs) meeting the income criteria.

For senior citizens, Bajaj Finance Fixed Deposits offer higher interest rates, making them an excellent choice for stable and secure returns.
