In 2026, FY 2022-23 returns can still be filed as updated returns under Section 139(8A). Understand the windows, costs, and ITR discipline for future years.
ITR Filing FY 2022–2023
If you missed filing your income tax return for FY 2022–23 (Assessment Year 2023–24) or filed one that understated income, you are not entirely out of options in 2026. The Finance Act 2025 extended the updated return window under Section 139(8A) to 48 months from the end of the assessment year — giving you a runway up to 31 March 2028 to file an updated return for AY 2023–24. The cost is steep: an additional tax of 60% (rising to 70% from April 2027) on top of normal tax and interest. But it is almost always cheaper than waiting for a reassessment notice under Section 148, especially now that AIS data has made the department's information advantage very real.
What Is Still Open for FY 2022–23 in 2026
Three routes remain available, each with distinct eligibility conditions:
- Updated return under Section 139(8A) — available until 31 March 2028 for AY 2023–24, subject to hard restrictions detailed below.
- Section 119(2)(b) condonation — for delayed refund claims where you can demonstrate genuine hardship. Filed as an application to the Principal Commissioner of Income Tax (PCIT) or Commissioner of Income Tax (CIT).
- Response to department notices — if CPC has issued an intimation under Section 143(1)(a) or the Assessing Officer has issued a notice under Section 148, you respond within the time given in the notice itself.
Everything else — the original return under Section 139(1), the belated return under Section 139(4), and the revised return under Section 139(5) — closed permanently on 31 December 2023. There is no voluntary route to file or revise for FY 2022–23 that reduces your tax liability. The updated return only moves in one direction: it can increase what you pay, never reduce it.
Original AY 2023–24 Timelines: Closed, But Not Irrelevant
Understanding when those windows closed matters because they determine what carry-forwards survived and what penalty windows are now open against you.
| Category | Due date | Late fee u/s 234F |
|---|---|---|
| Non-audit individuals and HUFs | 31 July 2023 | Rs. 5,000 (Rs. 1,000 if income ≤ Rs. 5 lakh) |
| Tax audit cases (Section 44AB) | 31 October 2023 | Nil (if filed by this date) |
| Transfer pricing cases | 30 November 2023 | Nil (if filed by this date) |
| Belated return (Section 139(4)) | 31 December 2023 | Rs. 5,000 or Rs. 1,000 |
| Revised return (Section 139(5)) | 31 December 2023 | Nil |
Why these closed dates matter now:
- A return filed after 31 July 2023 but before 31 December 2023 incurred the Section 234F late fee. That fee is on the permanent record and cannot be refunded.
- A return not filed at all by 31 December 2023 means no carry-forward of business losses under Section 72 or capital losses under Section 74 for that year. That damage to future assessments is irreversible.
- Interest under Section 234A continues to run from the original due date on unpaid tax, compounding the cost of every month of delay.
- Section 143(1) intimations from CPC were issuable up to nine months from the end of the financial year in which the return was furnished. For returns filed in FY 2023–24 (e.g., belated returns filed in December 2023), the intimation window ran to 31 December 2024. If you received one, you should have received it by now; if you did not respond, check your portal inbox.
Section 139(8A) Updated Return: The Only Voluntary Path Left
Introduced by Finance Act 2022 and expanded by Finance Act 2025, Section 139(8A) allows you to file ITR-U — a form of updated return — to declare income you omitted, understated, or entirely missed in an earlier return. You can also file ITR-U if you never filed a return at all for that year.
For AY 2023–24, the time-based slabs work as follows (the assessment year ends on 31 March 2024):
| Window | Open until | Additional tax rate |
|---|---|---|
| Within 12 months from end of AY | 31 March 2025 | 25% — closed |
| Within 24 months from end of AY | 31 March 2026 | 50% — closed |
| After 24 months, within 36 months | 31 March 2027 | 60% — currently open |
| After 36 months, within 48 months | 31 March 2028 | 70% — opens 1 April 2027 |
As of May 2026, you are in the 60% additional tax window for AY 2023–24. This is the operative rate for any ITR-U you file today. The rate climbs to 70% from 1 April 2027 onward — so there is a financial incentive to act before that date if you know additional income needs to be declared.
How the Additional Tax Under Section 140B Is Calculated
The additional tax is not simply 60% of the income you omitted. It is computed on the net tax shortfall, defined as:
> Net shortfall = (Tax on updated total income + Interest u/s 234A + 234B + 234C + Fee u/s 234F) − (Tax, interest, and fee already paid or determined in the original/revised return)
Additional tax = 60% × Net shortfall
Surcharge (if applicable to your income slab) and Health & Education Cess at 4% apply on the underlying tax component, not on the additional tax percentage itself.
You must pay the full amount (net shortfall + additional tax) via a self-assessment challan — ITNS 280, Minor Head Code 400 — before submitting the ITR-U. The challan's BSR code, date, serial number, and amount are entered into the form. The portal will not let you submit without this. This is a strict precondition, not a procedural formality.
Worked Example: Rahul's Undisclosed Freelance Income
Facts:
- Rahul is a salaried individual. FY 2022–23 salary: Rs. 8,00,000. He also received Rs. 2,40,000 as freelance consulting fees — no TDS deducted by the payer, and Rahul did not declare this in his original return filed on 28 July 2023.
- His AIS for FY 2022–23 now shows Rs. 2,40,000 under "Other Income / Receipts" sourced from SFT data submitted by the client company.
Step 1 — Base tax on omitted income:
- Total income (updated): Rs. 8,00,000 + Rs. 2,40,000 = Rs. 10,40,000
- Assuming the additional Rs. 2,40,000 falls entirely in the 20% slab (new tax regime or old — adjust for deductions as applicable): Tax = Rs. 48,000
- Health & Education Cess @ 4%: Rs. 1,920
- Gross base tax: Rs. 49,920
Step 2 — Interest under Sections 234B and 234C (for non-payment of advance tax on the freelance income through the year): approximately Rs. 7,000 (exact figure computed by the ITR-U offline utility based on quarterly due dates).
Step 3 — Net shortfall: Rs. 49,920 + Rs. 7,000 = Rs. 56,920
Step 4 — Additional tax @ 60%: Rs. 56,920 × 60% = Rs. 34,152
Total outflow today: Rs. 56,920 + Rs. 34,152 = Rs. 91,072
Now compare with the reassessment scenario:
If the department issues a Section 148 notice and the AO establishes under-reporting (no deliberate concealment): penalty under Section 270A = 50% of tax = Rs. 24,960.
If established as misreporting (deliberate concealment of income): penalty = 200% of tax = Rs. 99,840.
Total liability in the misreporting scenario: Rs. 49,920 (tax) + Rs. 7,000 (interest) + Rs. 99,840 (penalty) = Rs. 1,56,760 — plus the time cost, professional fees, and stress of navigating an assessment proceeding that can stretch over two to three years.
Filing the updated return today closes the matter for Rs. 91,072. The decision is straightforward.
What an Updated Return Cannot Do: The Hard Restrictions
ITR-U is a one-way door. Before you prepare it, confirm that none of these bars apply to your situation:
You cannot file an updated return if:
- It would result in a refund or an increase in a refund already claimed.
- It would reduce your tax liability below what was determined in the original or any prior return.
- It would increase a loss (claiming an additional expense to reduce business profit, for instance).
- A search under Section 132 or survey under Section 133A has been conducted for AY 2023–24.
- Any proceeding for assessment, reassessment, recomputation, or revision is pending or completed for that year.
- Prosecution has been initiated under Chapter XXII of the Income-tax Act for that year.
- You have already filed one updated return for AY 2023–24. Section 139(8A) permits exactly one ITR-U per assessment year.
The single most important practical implication: if you forgot to claim your Section 80C deductions or HRA exemption, the updated return is not the solution. You would have had to file a revised return under Section 139(5) by 31 December 2023. That window is permanently closed.
Section 148 Reassessment: Know Your Exposure Window
Even if you do nothing in 2026, the department may act. Under the revamped Section 149 framework (post Finance Act 2021), reassessment notices can be issued:
- Within 3 years from the end of the relevant AY: for all cases of escaped assessment, regardless of amount.
- Beyond 3 years and up to 10 years: only where the Assessing Officer has, in his possession, information suggesting escaped income of Rs. 50 lakh or more for the year.
For AY 2023–24:
- The 3-year window closes on 31 March 2027.
- The 10-year window (high-value cases) closes on 31 March 2034.
The AIS and Project Insight data — which consolidates SFT filings from banks, registrars, mutual funds, stock brokers, and insurers — is exactly what the department uses to identify gaps between declared income and third-party reported transactions. If your AIS shows a transaction you have not explained in your return, a notice before March 2027 is a realistic possibility.
Note the strategic timing: voluntarily filing ITR-U before the 3-year notice window closes (March 2027) and before the rate rises to 70% (April 2027) gives you the lowest possible cost to resolve the matter. Waiting until after March 2027 saves nothing — the 10-year window remains open for significant cases, and the additional tax rises.
Section 119(2)(b) Condonation: Reviving a Missed Refund
If you were entitled to a refund for FY 2022–23 but never filed your return, or filed it so late that the refund cannot be processed through normal channels, Section 119(2)(b) offers a limited remedy.
How the application works:
- File a written application to the PCIT or CIT having jurisdiction over your PAN.
- Demonstrate genuine hardship — documented illness, bereavement, natural calamity, or another event beyond your control that prevented timely filing. Courts have interpreted "genuine hardship" narrowly; bureaucratic oversight is generally not accepted.
- Attach all supporting documents: medical certificates, death certificates, insurance claim records, etc. Also attach a draft of the belated return you propose to file.
- CBDT Circular No. 9/2015 (and subsequent clarifications) sets the monetary limit for PCIT/CIT to directly condone delays at refunds up to Rs. 50 lakh. Cases above this threshold require CBDT's own approval, which takes significantly longer.
What condonation does not cover:
- Tax dues (it is strictly for recovering refunds, not for reducing your outstanding tax).
- Delays that are not accompanied by documented hardship evidence.
- Cases where the bar on ITR-U also applies (search, survey, prosecution).
If your FY 2022–23 refund is substantive — Rs. 2 lakh or more — applying now rather than later is advisable. Disposal timelines vary from four to eighteen months depending on the jurisdiction and documentation quality. The refund processing clock starts from the date condonation is granted, not from your original due date.
The AIS/TIS Trigger: Why the Department Knows Before You Act
The Annual Information Statement (AIS) and Taxpayer Information Summary (TIS) on the income tax portal aggregate data from:
- SFT (Statement of Financial Transactions): banks (savings account credits above Rs. 10 lakh, term deposits above Rs. 10 lakh), mutual funds (purchases above Rs. 10 lakh), registrars (property sales above Rs. 30 lakh), stock brokers (equity transactions above Rs. 10 lakh turnover)
- TDS/TCS returns: salary, bank interest, professional fees, rent paid by companies
- GST returns: annual turnover cross-referenced against declared business income
- Foreign remittance data: LRS transactions
By May 2026, the department has had this data for FY 2022–23 for nearly three years. A mismatch between your AIS entries and your filed return is already visible in the department's analytical systems.
Before deciding whether to file ITR-U, follow this reconciliation sequence:
- Log in to www.incometax.gov.in → AIS/TIS tab.
- Download the AIS PDF for FY 2022–23 and the TIS summary.
- Map each AIS entry line by line against your filed return's schedules.
- For entries in AIS that do not appear in your return, determine whether the entry represents: (a) income you omitted, (b) a duplicate or incorrect entry you should dispute, or (c) income already included under a different head.
- For incorrect entries, raise feedback in the AIS portal immediately. This creates a documented trail showing you identified and disputed the entry. Do this before filing ITR-U, not after.
- Only after completing this reconciliation should you decide whether — and for exactly how much — to file an updated return.
Unaddressed mismatches between AIS and your return are the most common trigger for Section 148 notices. Addressing them proactively, either by filing ITR-U or by raising AIS feedback, closes that exposure.
Step-by-Step: Filing ITR-U on the Income Tax Portal
- Log in to www.incometax.gov.in using your PAN and password.
- Navigate to e-File → Income Tax Returns → File Income Tax Return.
- Select AY 2023–24 and choose Updated Return (ITR-U) as the filing type.
- The portal loads a pre-filled form using your original return data and AIS information. Review carefully — the pre-fill is a starting point, not a verified calculation.
- Add the omitted income in the correct schedule: Schedule OS (other sources), Schedule BP (business/profession), Schedule CG (capital gains), or the appropriate head.
- The ITR-U offline utility computes the additional tax under Section 140B automatically. Note the exact challan amount.
- Pay the entire amount (net shortfall + additional tax) via ITNS 280, Minor Head 400 (Self-Assessment Tax) at the tax payment portal or your bank's net banking. Do not file the return before payment clears.
- Enter the challan details in the ITR-U form: BSR code, challan date, serial number, and amount paid.
- Select the reason for filing from the portal's dropdown — typically "Income not reported correctly" or "Return not filed earlier".
- Verify and submit using Aadhaar OTP, net banking EVC, or Digital Signature Certificate (DSC).
- Download and store the ITR-V acknowledgment. Keep the challan counterfoil as well.
Critical warning: The ITR-U cannot be revised after submission. Section 139(8A) allows exactly one updated return per assessment year. Verify every figure — income amounts, challan details, and deduction claims — before you click Submit.
Common Mistakes That Derail ITR-U Filings
Filing ITR-U to claim a missed deduction. Section 139(8A) cannot reduce tax. If you forgot to claim an 80D premium or an LTA exemption, the updated return will be rejected. This is the single most common misconception about ITR-U.
Computing additional tax on gross omitted income instead of net shortfall. If TDS was deducted on the omitted income (say, TDS on FD interest), that TDS credit reduces the net shortfall. Calculating 60% on the gross income rather than the net shortfall results in overpayment. Use the ITR-U utility — do not attempt this calculation manually unless you are very comfortable with Section 140B's formula.
Not reconciling AIS before filing. Taxpayers sometimes file ITR-U to address one omission they remember, without checking AIS for others. Filing ITR-U closes the voluntary disclosure window for that year — the one-per-year rule applies. A second undisclosed item discovered post-filing cannot be added to another ITR-U.
Waiting past 31 March 2027 to save on the higher rate. After March 2027, the rate rises from 60% to 70% and the 3-year reassessment window closes. Some taxpayers read this as "the risk reduces after March 2027." It does not — the 10-year window for high-value cases remains open until March 2034, and the additional tax rate is now higher.
Submitting without saving the challan details. The ITR-U cannot be submitted without challan details, but taxpayers sometimes pay the challan and then lose the BSR code or serial number before the portal session closes. Always note challan details immediately on payment, or download the Challan 280 receipt before returning to the ITR-U form.
Lessons for FY 2025–26 and Beyond
The FY 2022–23 situation is a case study in the true cost of deferred compliance. Apply these lessons to current filings:
- Carry-forward of business losses under Section 72, speculative losses under Section 73, and capital losses under Section 74 requires filing on or before the Section 139(1) due date. Missing this date by even one day can permanently extinguish the carry-forward. For a start-up with Rs. 20 lakh of business losses in FY 2025–26, a missed due date means losing a tax asset worth Rs. 4–6 lakh (at a 20–30% effective rate) across the eight-year carry-forward window.
- Belated returns under Section 139(4) preserve some carry-forwards but not business losses under Section 72. Filing late is categorically inferior to filing on time, even if the numbers are identical.
- Build a pre-filing checklist for FY 2025–26 at least 60 days before the July 2026 due date. Reconcile AIS, TIS, Form 26AS, bank FD interest certificates, broker capital gains statements (separate reports for equity, F&O, debt mutual funds), dividend income, and rent agreements — in May, not July.
- The AIS pre-fill on the portal is a starting point, not a finished return. Banks occasionally under-report savings account interest in Form 26AS. Brokers may show equity turnover without correctly splitting speculative and non-speculative income. You are legally responsible for the accuracy of what you submit.
- Sections 234A, 234B, and 234C interest runs at 1% per month from the original due date. On Rs. 3 lakh of unpaid tax, six months of 234A alone adds Rs. 18,000 — more than the Section 234F late fee. Filing on time costs nothing; filing late costs money every single month.
Key Takeaways
- The only live voluntary option for FY 2022–23 in May 2026 is the updated return under Section 139(8A), available until 31 March 2028. All other original, belated, and revised return windows closed on 31 December 2023.
- As of today (May 2026), filing ITR-U for AY 2023–24 attracts 60% additional tax on the net shortfall of tax and interest. This rate rises to 70% from 1 April 2027.
- ITR-U is a one-way instrument. It cannot reduce tax, increase a refund, or claim a missed deduction. One updated return per assessment year — verify everything before submitting.
- Section 148 reassessment notices can be issued until 31 March 2027 for ordinary cases and until 31 March 2034 for high-value cases (escaped income ≥ Rs. 50 lakh). As the worked example shows, voluntary disclosure at 60% additional tax is almost always cheaper than facing a 200% Section 270A misreporting penalty.
- Section 119(2)(b) condonation is the only route to recover a missed refund for FY 2022–23. It requires documented genuine hardship and an application to the PCIT or CIT. It does not help with tax dues.
- Download and reconcile your AIS for FY 2022–23 today. Unaddressed mismatches between AIS data and your filed return are the primary trigger for Section 148 notices. Raising AIS feedback on incorrect entries is a low-cost, proactive step that creates a documented audit trail.
- For FY 2025–26 and every year going forward: file before the Section 139(1) due date. The compounded cost of missing it — lost carry-forwards, Section 234A/B/C interest, Section 234F fees, and the eventual 60–70% additional tax on undisclosed income — is always a multiple of the effort required to file on time.
