Major Tax Change: Form 121 Replaces 15G and 15H for TDS Exemption
Retirees, pensioners, and individuals dependent on bank interest or post-office deposits must prepare for a significant tax overhaul. The familiar Forms 15G and 15H, traditionally used to avoid Tax Deducted at Source (TDS), will be phased out starting April 1, 2025, under the Income Tax Act. They will be replaced by a single, consolidated Form 121, introducing updated eligibility criteria, a new two-year income tax return disclosure mandate, and specific provisions for taxpayers approaching senior citizen status.
Key Provisions for Senior Citizens and New Eligibility Rules
Tax experts emphasize that the new form is designed for individuals with an estimated nil tax liability for the financial year, enabling them to self-declare and prevent banks, post offices, and other deductors from withholding TDS on specified incomes. A crucial benefit applies to those turning 60 during the financial year. International tax expert Mukesh Patel explained, "Resident individuals who celebrate their 60th birthday at any point in the financial year will be treated as senior citizens for the entire year for declaration purposes. This allows them to use Form 121, provided their total estimated tax payable is zero."
Under the new tax regime, senior citizens can enjoy nil tax liability on income up to Rs 12 lakh, thanks to available rebates. This threshold extends to Rs 12.75 lakh when the standard deduction for salary or pension income is applied, making Form 121 particularly advantageous for those relying on bank interest, post-office deposits, or pension payments.
Stricter Limits for Non-Senior Citizens and Eligible Income Types
For non-senior citizens, Hindu Undivided Families, Associations of Persons, and Bodies of Individuals, the eligibility criteria are more stringent. Their total income must not exceed the basic exemption limit: Rs 4 lakh under the new tax regime or Rs 2.5 lakh under the old regime. Form 121 can be filed against various income types, including:
- Interest on securities
- Bank and post-office deposits
- Dividends
- Rental income
- Insurance commission
- Insurance-related payments, including bonuses
- Withdrawals from recognised provident funds
However, it cannot be used to avoid TDS on professional fees, technical services, or contract payments, which remain subject to separate regulations.
New Disclosure Requirements and Expert Recommendations
A significant addition is the two-year income tax return disclosure requirement. Taxpayers filing Form 121 must now provide details from the previous two years, including acknowledgement numbers and reported income. Tax professionals warn that this increases the stakes for incorrect declarations, potentially leading to penalties or audits.
Patel cautioned, "While Form 121 simplifies the process on paper, taxpayers must remain vigilant. Eligibility still hinges on estimated income, the choice of tax regime, and earnings like capital gains taxed at special rates, which are not eligible for tax rebate benefits."
Experts advise taxpayers to first assess whether TDS applies to their income. If bank interest falls below the prescribed threshold, filing Form 121 may be unnecessary. For those who need to file, early submission in April is recommended to prevent tax deductions at the start of the financial year, ensuring smoother financial management for retirees and pensioners.
