Nil Income Tax Return: Why Filing Even When No Tax Is Due in 2026-27

Many people with income below the exemption limit skip an Income Tax Return. They assume filing is pointless when no tax is due. A Nil return can still help with future money needs. It also supports refund claims when tax was already deducted. It also keeps Income Tax department records current for the year.

Under income tax rules, taxpayers below the basic exemption limit need not file. Yet many still submit a Nil Income Tax Return. They often want formal income proof for lenders. Visa offices and overseas institutions may also ask for ITR copies. Filing also helps recover eligible TDS, even with low income.

A Nil Income Tax Return creates an official income trail for that financial year. Banks and card issuers may request ITR acknowledgements for credit checks. Some employers and institutions also use ITR as supporting income proof. Where TDS was cut on salary or interest, filing matters. A return is required to claim any refund due.

Even when gross receipts look higher, deductions can lower taxable income. Some taxpayers then fall below the exemption threshold after adjustments. In those cases, tax deducted at source can become excess. The Income Tax Return is the tool to reconcile this. Without filing, the refund process usually cannot begin.

Income Tax Return deadlines for FY 2025-26 vary by income type and audit needs. Non-audit individuals file earlier than business taxpayers. The due date can change if the department issues a notification. Still, taxpayers often plan using the standard dates. Missing the deadline can still allow a belated return later.

Category	Applicable ITR Forms	Due Date (FY 2025-26)

Non-audit individuals include salaried employees, pensioners, and many investors. They usually file ITR-1 or ITR-2 by 31 July 2026. Non-audit business or profession cases use ITR-3 or ITR-4 by 31 August 2026. Audit cases also use ITR-3 or ITR-4 by 31 October 2026. Belated filing ends on 31 December 2026.

Income Tax Return tax slabs under new and old regimes

The basic exemption limit changes with the chosen tax regime. Under the new tax regime, income up to ₹4 lakh is tax-free. Income from ₹4 lakh to ₹8 lakh is taxed at 5%. Higher slabs apply as income rises. The top rate under this structure is 30%. It applies once income exceeds ₹24 lakh.

Under the old tax regime, the exemption limit is ₹2.5 lakh. Income from ₹2.5 lakh to ₹5 lakh is taxed at 5%. Income between ₹5 lakh and ₹10 lakh attracts 20%. Amounts above ₹10 lakh are taxed at 30%. The regime choice can affect refunds when TDS was deducted during the year.

Tax Regime	Income Range (₹)	Tax Rate
New tax regime	Up to 4,00,000	Nil
New tax regime	4,00,001 – 8,00,000	5%
