Why Filing ITR Is Essential
Filing your income tax return is not just a legal obligation; it offers significant financial benefits. A filed ITR serves as a crucial document for loan approvals, visa applications, and credit card issuance. It also enables you to carry forward losses, claim refunds on excess TDS deducted, and establish financial credibility.
Who Must File ITR in 2026?
For Assessment Year 2026-27, the basic exemption limits are: Rs. 3,00,000 for individuals below 60 years under the old regime, Rs. 3,00,000 under the new tax regime, Rs. 3,00,000 for senior citizens aged 60-80, and Rs. 5,00,000 for super senior citizens above 80 years.
