ITR Due Dates for AY 2026–27 

The Central Board of Direct Taxes (CBDT) operates on a tiered deadline system. Identifying your category is the first step in avoiding the late-filing trap.

* Note: The due dates above apply to the general taxpayer categories. Certain taxpayers may have different due dates if notified by the CBDT or if covered under specific provisions of the Income-tax Act.

Late Filing Fee Under Section 234F 

The moment the clock strikes midnight on July 31, 2026, Section 234F is invoked. Unlike other penalties that may be subjective, this is a mandatory fee for taxpayers who are required to furnish an Income Tax Return under Section 139(1) and file it after the due date.

  • Total Income Exceeding Rs. 5 Lakh: A flat late fee of Rs. 5,000 applies.

  • Total Income Up to Rs. 5 Lakh: The fee is capped at Rs. 1,000.

Interest on Late Filing: Sections 234A, 234B & 234C 

For the fiscal journalist, the "hidden" cost of late filing is often found in the interest sections. While the 234F fee is a one-time hit, interest charges act like a running meter. Below are some major charges that apply. 

Section 234A: Delay in Filing

If you have outstanding tax dues, Section 234A imposes an interest of 1% per month (or part of a month) on the unpaid amount. This interest is calculated from the day immediately following the due date until the date you actually file the return. This may also apply if you changed jobs during the year and did not share your previous employer's Form 16 or salary/TDS details with your new employer, resulting in unpaid tax.

Section 234B: Default in Advance Tax

If your total tax liability for the year exceeds Rs. 10,000, you are required to pay Advance Tax. If you fail to pay at least 90% of your assessed tax by March 31, interest at 1% per month is levied from April 1 until the date of your assessment.

Section 234C: Deferment of Advance Tax Instalments

Advance tax must be paid in four instalments during the financial year. Taxpayers are generally required to pay at least 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Failure to pay the required amount by these due dates attracts interest under Section 234C, even if the full tax is paid later. Taxpayers opting for the presumptive taxation scheme under Sections 44AD or 44ADA can pay 100% of their advance tax by March 15.

Major Consequences of Filing ITR After the Due Date 

Financia‌l los‌s is not always measured‌ in immediate ​cash‌ outflows. Late fi‌ling‌ results in t‍he forfe​iture‌ of several statutory "rig‌hts" th​at could sav‌​e you lakhs in the futur‍e.

  1. N‌o Carry Forward of L‌osses: It is perhaps the most damaging con​se​quence f‌or ent​r‌e‌preneurs and investo​rs. If you file aft​er the July 31‌ deadline, ​yo​u cannot carry forward bus‌iness​ losses,‍ capital‍ losse‌‌‍‌s (long-term or short-term), or losses from ​o​w​ning raceho‍rses ​t‍o f​uture years. These​ losses‍ could otherwi‍se be used to off‍set future‍ p‌r​ofits, signif‌icantly redu​cin‌g ​your tax bill ‌in subsequent years.

  2. Delayed Refunds:‌‍ If‍ t‍h‌e government owes you money, fili‍ng l​a‌te ensures you ​remain at ‍the back of the queue. Inte‌res​‍t ​‍on refund‍s ​is also calculated from the dat‌e of fi‌ling ​in late‍ cases, meaning y‍ou l​ose out on po​tent​ial interest in‌​come.

  3. Loan and V‍isa Complications: Fina‌ncial institutions typically req‍ui‌re th‍e last three ​ye​ars of ITRs to assess creditworthiness. A ‍late-filed ITR, or a "Belated​ Retu​rn," ​can be a r‍ed flag for credit office‌rs,‍ potent‌ially‍ impacting your eligibility for home loans or competitive​ interest ‌rates (which currently‌ start as ‌low as 7.2‍‌5% p.a.).

Important Penalty Sections Every Taxpayer Should Know 

The Income Tax Act is peppered with specific penalties for varied defaults. Below is a breakdown of the most critical sections applicable for AY 2026-27:

Under-reporting and Misreporting (Section 270A)

Honesty is the best policy, and Section 270A reinforces this. If you fail to disclose income, the penalty is 50% of the tax payable on that amount. If the under-reporting is deliberate (e.g., misrepresentation of facts or false entries), the penalty escalates to 200% of the tax.

Aadhaar-PAN Linking (Section 234H)

Today, compliance starts with identity. If you have not intimated or linked your Aadhaar with your PAN, a fee of Rs. 1,000 is levied. Without this linkage, your ITR cannot be processed.

Audit Defaults (Section 271B)

For businesses with a high turnover, failing to get accounts audited by a Chartered Accountant is a major infraction. The penalty is 0.5% of total sales/turnover, capped at Rs. 1,50,000.

TDS/TCS Defaults (Section 271H)

If you are a deductor (like an employer or a business paying rent), failing to file TDS returns on time can lead to penalties ranging from Rs. 10,000 to Rs. 1,00,000, in addition to the daily late fee of Rs. 200 under Section 234E.

Stricter Rules for Private Limited Companies

The corporate sector faces a more rigorous compliance environment. For Private Limited Companies, the ITR filing is non-negotiable.

  • Section 271F: While largely replaced by 234F for individuals, certain failures to file for companies can trigger a penalty of Rs. 5,000 per day while the default continues.

  • Inaccurate Details (Section 271AAB): If a search/survey reveals undisclosed income, companies can face penalties ranging from 30% to 60% of the tax sought to be evaded.

  • Section 271BA: Failure to furnish a report from an accountant regarding international transactions results in a flat penalty of Rs. 1,00,000.

Belated Return vs Revised Return 

If you miss the July 31 deadline, you have until December 31, 2026, to file a Belated Return. While you pay the Section 234F fee and interest, it is always better to file a belated return than to remain a non-filer.

If you filed on time but made an error, you can file a Revised Return by March 31, 2027. However, be aware of the new Section 234-I, which introduces a fee for filing a revised return very late in the cycle:

  • Rs. 1,000 if income is up to Rs. 5 Lakh.

  • Rs. 5,000 for others.

Note: It applies if the revision happens beyond 9 months from the end of the assessment year.

Final Thoughts

Missing the ITR filing deadline can trigger multiple financial consequences that extend beyond a simple late filing fee. 

Taxpayers may face interest under Sections 234A, 234B, and 234C, lose the ability to carry forward certain losses, experience delays in tax refunds, and even affect future loan or visa applications.
