For young earners in India, filing income tax returns (ITR) is a critical task that ensures legal compliance and supports financial activities such as loan applications. Individuals earning above ₹2.5 lakh under the old tax regime or ₹3 lakh under the new regime must file their returns. The process begins with gathering essential documents, including Form 16 from employers, bank interest certificates, and investment statements. The e-filing system pre-fills much of the data, but taxpayers must validate it against their records. The annual information statement (AIS) plays a crucial role in this process, providing a detailed view of all financial transactions. Taxpayers must reconcile their earnings from Form 16 with the AIS and Form 26AS to avoid discrepancies that could trigger tax notices. After submission, e-verification is required within 30 days to prevent late fees. Common pitfalls include using the incorrect ITR form and neglecting to report all income sources. Importantly, taxpayers can revise their returns if errors are found, but must do so by December 31 of the assessment year.
