Individuals who have not yet filed their income tax return (ITR) for assessment year 2026-27 face a fast-approaching July 31, 2026 deadline, according to Business-Today. Those with professional or business income have more time: August 31, 2026 for non-audit cases and October 31, 2026 for others. Missing the deadline triggers late fees, penal interest and the loss of certain tax benefits, the report said.
Who Must File: Exemption Limits and Mandatory Conditions
An income tax return must be filed if taxable income exceeds the basic exemption limit, Business-Today reported. Under the new income tax regime, income up to Rs 4 lakh is exempt; under the old regime, the limit is Rs 2.5 lakh. Filing is mandatory when taxable income crosses these thresholds, even if the taxpayer only intends to claim the Section 87A rebate.
Filing can also become compulsory under certain specified conditions, including:
- Electricity expenses of Rs 1 lakh or more
- Spending over Rs 2 lakh on foreign travel
"It is advisable to ensure continuity in filing of the ITR as beyond tax compliance, ITRs serve as an important income proof for loans, visa applications etc. Moreover, in case of overseas employment, such ITR is required to claim foreign tax credits in the overseas country, with respect to any double taxation of income as per the provisions of the relevant tax treaty," says Chander Talreja, Partner, Vialto Partners.
Consequences of Missing the July 31 Deadline
Missing the due date or failing to file altogether can have far-reaching consequences, Chander Talreja of Vialto Partners explained in the Business-Today report. Key penalties include:
- Late fee of up to Rs 5,000 (Rs 1,000 where income does not exceed Rs 5 lakh)
- Penal interest of 1% per month on any outstanding tax from the original due date until the actual filing date
- Interest on defaults in payment of advance tax continuing to accrue
| Deadline / Consequence | Amount / Date |
|---|---|
| Late fee (income above Rs 5 lakh) | Up to Rs 5,000 |
| Late fee (income up to Rs 5 lakh) | Rs 1,000 |
| Penal interest | 1% per month |
| Belated return deadline (for tax year 2025-26) | December 31, 2026 |
Taxpayers also lose the flexibility to switch between the old and new tax regimes if they file late, because the new regime is the default and returns filed after the due date are automatically processed under it. Additionally, losses (other than house property loss) cannot be carried forward to subsequent years.
Belated, Revised and Updated Returns
Even after missing the deadline, taxpayers can still file a belated return within nine months following the close of the tax year — i.e. by December 31, 2026 for tax year 2025-26 — subject to the late fee, Business-Today reported. The Finance Act 2026 provides further flexibility: taxpayers can revise any original or belated ITR within 12 months following the close of the tax year (i.e. by March 31, 2027) on payment of a fee of Rs 5,000 or Rs 1,000 as applicable.
If a taxpayer misses even the belated return window, an Updated ITR (ITR-U) can still be filed on payment of penal additional tax. However, an updated return can be filed to reduce losses claimed earlier but not to claim any refund.
Risks of Not Filing at All
If taxpayers do not file the ITR where required under the law, the consequences are wider, Chander Talreja told TOI. The tax authorities may:
- Send communications seeking reasons for non-filing, especially where high-value financial transactions are reported through Form 26AS/AIS
- Forfeit refunds arising from excess tax deducted at source (TDS)
For executives and investors managing personal tax compliance or payroll for overseas assignees, the July 31 deadline is a critical date. The 1% monthly interest on outstanding tax, combined with the loss of loss-carry-forward benefits and the inability to switch tax regimes, makes timely filing materially cheaper than remediation later.
