In a significant update for retirees and pensioners in India, particularly in Gujarat, those turning 60 during the financial year 2026-27 can now claim senior citizen benefits for the entire year using the new Form 121. This form, which replaces the previous Forms 15G and 15H, is designed to simplify the tax filing process and is effective from April 1, 2025. According to Mukesh Patel, an international tax expert, individuals who reach 60 can declare themselves as senior citizens for tax purposes throughout the year, even if their birthday falls later in the financial year. This allows them to benefit from a nil tax liability on income up to ₹12 lakh (approximately $15,000 USD), which increases to ₹12.75 lakh when considering standard deductions for salary or pension income. Form 121 can help avoid TDS on various income sources, including bank interest and pension, but it cannot be used for professional fees or contract payments. A new requirement mandates that taxpayers disclose details from their income tax returns for the previous two years when filing this form. Tax experts advise that while Form 121 simplifies the process, taxpayers should ensure their estimated income qualifies for the benefits and file early in April to prevent TDS deductions.
