ITR Filing for FY 2025-26: New Deadlines, Form Changes, and Why Businesses Should File Early

The new financial year starts on April 1, 2026, marking the official opening of ITR filing for FY 2025-26. Before postponing this task, note that the deadline structure has changed and early filing offers greater strategic benefits than in previous years.

This guide explains the Union Budget 2025 changes to ITR filing, the new form-specific deadlines, who is affected, and why businesses, especially SMEs, funded startups, and companies with multiple directors, should file as early as possible between April and June.

​

What Has Changed: The New Deadline Structure for FY 2025-26

The Union Budget 2025 introduced a new ITR filing deadline structure. Instead of a single deadline for all taxpayers, the due date now depends on the specific ITR form required. If your income type, business structure, or turnover category changed during FY 2025-26, your applicable form and deadline may also have changed.

For the first time, there is a significant deadline difference between businesses requiring a statutory audit and those that do not. This distinction affects cash flow and planning, especially for companies awaiting audit completion before filing.

Taxpayer Category	ITR Filing Deadline FY 2025-26
Salaried individuals (ITR-1, ITR-2)	July 31, 2026
Business / profession, no audit required (ITR-3, ITR-4)	July 31, 2026
Companies, LLPs, and businesses requiring statutory audit	October 31, 2026
Taxpayers with international / transfer pricing transactions	November 30, 2026
Revised return (correcting original filing)	December 31, 2026
Belated return (filed after due date)	December 31, 2026 with late fee
Updated return — ITR-U (with additional tax)	Up to 4 years from end of assessment year

Important: These deadlines are based on Budget 2025 provisions and current CBDT guidance. As the CBDT may issue deadline extensions, please check the income tax portal or consult your tax advisor for updates closer to the due date.

Key Form Changes for FY 2025-26

ITR-1 (Sahaj) — Salaried individuals with simple income

The ITR-1 form now requires more detailed salary information, including the employer’s PAN, TDS certificate references, and separate fields for HRA claims and LTA exemptions. Employees who received ESOPs, RSUs, or sweat equity in FY 2025-26 may not be eligible for ITR-1 and should confirm with their tax advisor if ITR-2 is required.

ITR-3 — Individuals and HUFs with business or professional income

The Schedule BP (Business Profit) section has been updated to align with accounting standards and capture more detailed information on digital receipts, expense categories, and depreciation claims. Businesses exceeding the Rs. 1 crore turnover threshold and not using presumptive taxation must maintain and report accounts in the new format.

ITR-4 (Sugam) — Presumptive taxation scheme

The turnover threshold for presumptive taxation under Section 44AD now depends on the proportion of cash receipts. If more than 5% of business receipts were in cash during FY 2025-26, the upper limit for the presumptive scheme is Rs. 2 crore. If all receipts were digital or through banking channels, the limit is Rs. 3 crore. Exceeding the applicable threshold and still filing under presumptive taxation often triggers scrutiny notices.

​

Why Filing Early Is a Smart Business Decision in FY 2026

Many businesses view ITR filing as a last-minute task, often completed in July or October when advisors are busiest. This approach misses key advantages. Filing in April or May offers several benefits that can positively impact your business throughout the year.

Faster refund processing

If your business or directors have excess TDS deducted on interest, professional fees, rent, or salary, filing early results in faster refund processing. The Income Tax Department generally processes refunds in the order returns are filed. Early filers usually receive refunds within 15 to 30 days of e-verification, while late filers may wait 60 to 90 days or more. For businesses with Rs. 5 to 10 lakh in TDS refunds, this timing difference can significantly impact cash flow.

More time to correct errors before the deadline

A revised return can be filed until December 31, 2026, but only after the original return is submitted. Filing in April gives you up to five months to correct any discrepancies without penalty. Filing in October reduces this window to just two months. Early filing provides the time needed to address complex income or GST reconciliation issues.

Stronger position for loans, credit, and investment

Banks and NBFCs require a verified ITR for the latest financial year when assessing business loans, working capital lines, or director personal loans. Having a filed and verified ITR for FY 2025-26 by May or June 2026 strengthens your credit application compared to competitors who have not yet filed. This is especially important for businesses seeking loans between July and September, when funding needs are often highest.

Visa applications for the US, UK, European Union, and Australia often require ITRs for the past two to three years as proof of financial standing. Early filing ensures your documentation is up to date and ready for any travel or business opportunity.

Preservation of carried-forward losses

Business losses, capital losses, and unabsorbed depreciation can only be carried forward if the ITR is filed by the due date. Filing after July 31 (for non-audit cases) or October 31 (for audit cases) results in losing this benefit. For businesses with losses in FY 2025-26, especially startups or those facing challenging conditions, missing the deadline means permanently forfeiting a significant tax advantage.

​

What Businesses Need to Prepare Now

The filing window opens on April 1, 2026. To file early, begin gathering and reconciling the following documents before the new financial year starts:

• Form 26AS and Annual Information Statement (AIS) — download from the Income Tax portal and reconcile every item against your books of account before filing
• All TDS certificates — Form 16 from employers, Form 16A from banks and clients, Form 16B from property transactions
• Audited financial statements or provisional accounts for FY 2025-26 (if audit is complete) or reliable provisional accounts if the audit is in progress
• GST returns (GSTR-1 and GSTR-3B) reconciled against the revenue and input tax credit figures in your books, discrepancies between GST and ITR are a primary trigger for income tax scrutiny
• PF and ESIC payment challans, these are cross-verified against employer filings and must match your payroll expense claims.
• Bank statements for all current and savings accounts, including FD renewal receipts and interest credit confirmations
• Investment schedules, depreciation registers, and documentation for deductions under Sections 80C, 80D, 32, 35D, and any other applicable provisions

Common Mistakes to Avoid in FY 2025-26 Filing

• Not reconciling AIS before filing. The Annual Information Statement records nearly all financial transactions reported to the Income Tax Department by third parties. Filing without matching your AIS to your declared income is the most common reason for scrutiny notices today.
• Using the wrong ITR form. This is especially important given this year’s form changes. Filing ITR-1 instead of ITR-2 due to ESOP income, or using ITR-4 when your cash receipts exceed the limit, leads to a defective return notice and requires refiling.
• Forgetting foreign income or assets. If your company received foreign remittances, consultancy income from overseas clients, or has directors with foreign bank accounts, investments, or signing authority, these must be disclosed in Schedule FA and Schedule FSI. Non-disclosure carries severe penalties under FEMA and the Black Money Act.
• Missing TDS credit claims. TDS deducted on professional income, interest, or rent must be claimed in your return for the correct financial year. Many businesses underclaim TDS credit due to incomplete Form 26AS and AIS reconciliation, resulting in unclaimed refunds.
• Not e-verifying after filing. A return not e-verified within 30 days is considered not filed. Complete e-verification through Aadhaar OTP, net banking, or by sending a signed ITR-V to CPC Bengaluru to validate your filing.
