The due date for filing the income tax return for AY 2026-27 has arrived for taxpayers under presumptive taxation. If you run a small business under Section 44AD or work as a professional under Section 44ADA, and you have not filed yet, this is the moment to understand exactly what changes once the date passes.
The short answer is that you can still file. But the return changes character, and it costs you something. This guide explains what you lose, what you pay, and how to file both before and after the deadline.
Who This Applies To
Section 44AD covers small businesses with turnover up to the prescribed limit, who declare income at 6 percent of digital receipts and 8 percent of cash receipts.
Section 44ADA covers specified professionals such as doctors, lawyers, engineers, architects, accountants, technical consultants and interior decorators, who declare income at 50 percent of gross receipts.
Both are non-audit cases in most situations, which places the return under the standard Section 139(1) due date.
What Happens After the Due Date
Belated return under Section 139(4)
You can file a belated return up to 31 December 2026 for AY 2026-27, or before the assessment is completed, whichever is earlier. The form remains the same, ITR-4 Sugam. The computation remains the same. Only the filing section changes from 139(1) to 139(4).
Revised return under Section 139(5)
A belated return can now be revised. So a mistake in a late filing is still correctable up to 31 December 2026.
What You Lose by Filing Late
This is the part most taxpayers underestimate. The consequences, in order of financial impact:
1. You lose the option of the old tax regime
The new tax regime is now the default. To opt out and choose the old regime for business or professional income, Form 10-IEA must be filed on or before the due date under Section 139(1). If the due date passes without it, you are locked into the new regime for the entire year.
For a professional under 44ADA with substantial deductions under 80C, 80D, home loan interest and HRA, this single consequence can cost more than every other penalty combined.
2. Late fee under Section 234F
A flat fee of Rs. 5,000 applies. This reduces to Rs. 1,000 where total income does not exceed Rs. 5 lakh. Where income is below the basic exemption limit and no mandatory filing trigger applies, there is no fee.
3. Interest under Section 234A
Interest runs at 1 percent per month or part of a month on unpaid self-assessment tax, from the day after the due date until the date of filing. This is over and above interest under Sections 234B and 234C.
Remember that presumptive taxpayers must pay 100 percent of advance tax in a single instalment by 15 March. If that was missed, Section 234C interest is already running.
4. Carry-forward of losses is denied
Business loss and capital loss cannot be carried forward if the return is belated. House property loss and unabsorbed depreciation survive. This matters most where the taxpayer also has capital gains or a second business alongside the presumptive activity.
5. Deductions under Section 80AC are denied
Deductions under Sections 80-IA, 80-IB, 80-IAC, 80JJAA, 80P and related provisions are lost entirely if the return is filed after the due date. Deductions under 80C and 80D are not governed by 80AC, but under the new regime most of them are unavailable in any case.
6. Refund is delayed and interest on refund is reduced
Interest on refund under Section 244A is reduced for the period of delay attributable to the taxpayer.
7. Prosecution risk under Section 276CC
This provision remains on the statute for serious cases. It is rarely invoked where the tax shortfall is small, but it exists.
8. Weaker compliance profile for bank loans
This is the consequence that affects entrepreneurs most in practice. A belated return carries the late fee entry and a late acknowledgement date. When three years of income tax returns are submitted along with a project report for a bank loan, the credit officer sees the delay. It does not by itself reject a proposal, but it weakens the promoter's compliance record and invites questions during appraisal.
How to File a Belated Return
Step 1 — Log in at incometax.gov.in using your PAN and password.
Step 2 — Go to e-File, then Income Tax Returns, then File Income Tax Return. Select Assessment Year 2026-27 and choose Online mode or download the offline utility.
Step 3 — Select ITR-4 Sugam for presumptive income. If turnover exceeds the 44AD limit, or if there is capital gains income or more than one house property, ITR-4 is not available and you must use ITR-3.
Step 4 — Under the filing section field, select 139(4) for belated return. If this is left at 139(1), the utility will show a validation error.
Step 5 — Enter presumptive income. Under 44AD, declare 6 percent of digital receipts and 8 percent of cash receipts. Under 44ADA, declare 50 percent of gross receipts. Also fill the mandatory fields for sundry debtors, sundry creditors, stock in trade and cash balance, as ITR-4 will not validate without them.
Step 6 — Allow the utility to compute interest under 234A, 234B and 234C and the late fee under 234F. Pay the amount through the e-Pay Tax facility as self-assessment tax under minor head 300, then enter the challan details in the return.
Step 7 — Submit the return and complete e-verification within 30 days using Aadhaar OTP, net banking EVC, bank account EVC or digital signature.
This last step is critical. An unverified return is treated as never filed. This is the most common way taxpayers lose the belated filing window without realising it.
If 31 December 2026 Also Passes
Updated return under Section 139(8A), known as ITR-U
Once the belated window closes, the updated return remains available. Following the Finance Act 2025 amendment, the window is 48 months from the end of the relevant assessment year. For AY 2026-27, this runs until approximately 31 March 2031.
Additional tax applies on the tax and interest payable, at the following rates depending on when the updated return is filed, measured from the end of the assessment year:
- Within 12 months — 25 percent additional tax
- Between 12 and 24 months — 50 percent additional tax
- Between 24 and 36 months — 60 percent additional tax
- Between 36 and 48 months — 70 percent additional tax
Important restrictions apply. An updated return cannot be used to claim a refund, to increase an existing refund, to declare a loss, to increase a loss, or to reduce tax liability. It works only where additional tax is payable. It is also barred once proceedings under Section 148A have been initiated for the relevant year.
Condonation of delay under Section 119(2)(b)
Where a genuine refund is stuck and the updated return route cannot help, an application for condonation of delay can be filed online through the income tax portal to the jurisdictional authority. This is generally available within five years from the end of the assessment year, with monetary limits determining whether the application is decided by the PCIT, CCIT or CBDT.
An Important Point on Presumptive Continuity
Filing a return late does not by itself remove a taxpayer from the presumptive scheme.
Section 44AD(4) is triggered by declaring income lower than the presumptive rate, not by filing delay. A belated ITR-4 that still declares 6 percent or 8 percent keeps the five-year continuity intact.
However, if a taxpayer decides out of frustration to declare actual lower profits instead, the five year lock-out under Section 44AD(4) is triggered. From the following year, a tax audit under Section 44AB(e) becomes mandatory wherever income exceeds the basic exemption limit. This is a decision that should never be taken casually.
What You Should Do Today
If the due date has not yet closed in your case, file today and pay whatever self-assessment tax is due. The saving on the old tax regime option alone usually justifies the effort.
If the date has passed, do not wait for December. Every month of delay adds another one percent under Section 234A. File the belated return, pay the fee and interest, and complete e-verification within 30 days.
Keep a clean filing record. It is not only a tax matter. It is the foundation of your credit profile when you approach a bank for a business loan.
