Step-by-step ITR filing on the income tax portal, e-verification methods and the 30-day window, refund processing timelines and status tracking, Section 143(1) intimation scenarios, defective return and scrutiny assessment responses, and the three correction mechanisms — Revised Return, ITR-U, and Rectification
This lesson covers the mechanics of actually filing your ITR — what happens when you click "submit," how verification works, when refunds arrive, and what to do when the Income Tax Department sends you a notice afterward. It's the practical bridge between knowing what to file (Lessons 1-8) and the post-filing world.
For most filers, filing goes smoothly: submit, e-verify, wait for refund or confirmation. But things can go wrong — defective returns, scrutiny notices, refund delays, mismatched data. Understanding the post-filing landscape helps you respond appropriately rather than panicking when an email from the IT Department arrives.
We also cover the three "return correction" mechanisms — Revised Returns (Section 139(5)), Updated Returns (Section 139(8A)), and Rectification (Section 154) — and when each applies. Each has different timelines, restrictions, and consequences.
This is the last foundational lesson. Lessons 10-19 will cover career and population-specific situations in depth, building on the framework you have now.
A reminder on terminology: the Income Tax Act 2025 (effective April 1, 2026) renumbers these provisions but preserves the substantive framework. This lesson uses 1961 Act references applicable to FY 2025-26 income filed as AY 2026-27.
A few minutes of preparation prevents most filing problems.
Income Tax Department portal user guide; Form 26AS and AIS access procedures.
The portal supports multiple paths to file your ITR. Here's the standard workflow.
Step 1 — Login.
Step 2 — Navigate to filing.
Step 3 — Select filing mode.
Step 4 — Choose status.
Step 5 — Select ITR form.
The portal helps determine the correct form based on a brief questionnaire.
Step 6 — Reason for filing.
Step 7 — Pre-filled data review.
Step 8 — Complete each schedule.
For ITR-2 (most common comprehensive form), schedules include:
Step 9 — Review tax computation.
Step 10 — Verify summary.
Step 11 — Pay self-assessment tax (if owed).
Step 12 — Submit.
Step 13 — E-verify within 30 days.
Critical step — covered separately below.
incometax.gov.in user guide; CBDT filing procedures.
Filing alone doesn't complete your return. You must verify within 30 days, or the submission is treated as if it never happened.
Verify immediately after submission. Best practice is to e-verify within minutes of submitting. Aadhaar OTP takes 30 seconds.
If you cannot verify (Aadhaar mobile number changed, no Aadhaar, etc.). Use net banking EVC or DSC. Physical ITR-V is the last option and risky due to postal delays.
Section 139 of Income Tax Act 1961; CBDT notification on verification methods.
If you've overpaid (via TDS, advance tax, or excess), refund is due back. Here's what to expect.
Normal refund timeline.
| Stage | Time |
|---|---|
| ITR filing and e-verification | Day 0 |
| Processing under Section 143(1) | 7-45 days typical |
| Refund initiated by IT Department | After processing |
| Refund credited to bank account | 1-7 days after initiation |
Total typical timeline: 30-60 days from filing to refund credit.
What can delay refunds.
Checking refund status.
Method 1 — Income Tax portal. incometax.gov.in → Login → Services → Tax Pending Actions → Pending Action/Refund Status.
Method 2 — TIN-NSDL. tin.tin.nsdl.com/oltas/refund-status-pan.html → Enter PAN, AY, status.
Status meanings.
What to do if refund delayed beyond 90 days.
Refund interest. If refund is delayed beyond a reasonable period and the IT Department is at fault, you're entitled to interest at 0.5% per month under Section 244A. Calculated from April 1 of the AY (or from date of payment for excess advance tax) until refund credited. Automatically applied during processing if delay is significant.
Section 244A (refund interest) of Income Tax Act 1961; CBDT refund processing guidelines.
Most filers receive a Section 143(1) intimation after processing. It's not a notice in the alarming sense — it's a standard processing confirmation.
What it contains.
Four possible scenarios.
Scenario 1: No discrepancy. "As per ITR and IT Dept computation, the figures match." If refund due, it'll be processed. No action needed.
Scenario 2: Demand for additional tax. IT Department computed higher tax than you.
Common reasons:
Action: Review carefully. If you agree, pay the demand within 30 days. If you disagree, file rectification under Section 154 with documentation.
Scenario 3: Refund less than expected. IT Department computed lower refund than you. Same as Scenario 2 — review, agree or rectify.
Scenario 4: Refund more than expected (rare). IT Department found additional refund. Usually due to interest under Section 244A being added.
Timeline. Section 143(1) intimation must be issued within 9 months from the end of the FY in which return was filed. So for AY 2026-27 returns filed by July 2026, intimation typically arrives by March 2027.
What to do upon receipt.
Section 143(1) of Income Tax Act 1961; CBDT intimation procedures.
A more serious notice — your return has errors that prevent processing.
Common defects triggering Section 139(9).
The 15-day window. You have 15 days from receipt of notice to file a revised return correcting the defects. Extension can be requested with proper reason, granted at AO discretion.
Consequences of not responding.
Response procedure.
Common defects and fixes.
| Defect | Fix |
|---|---|
| Used ITR-1 but have capital gains beyond limit | Refile using ITR-2 |
| Foreign assets disclosed but used ITR-1 | Refile using ITR-2 with Schedule FA |
| Used ITR-4 (presumptive) but actual books required | Refile using ITR-3 with full books |
| Bank account not pre-validated | Pre-validate then refile |
| Verification failed | Re-verify using different method |
Section 139(9) of Income Tax Act 1961; CBDT defective return procedures.
A scrutiny notice means the IT Department wants to examine your return in detail. Rare for routine filers but consequential when it happens.
What triggers scrutiny.
Faceless assessment. Since 2020, most scrutiny is "faceless" — no physical interaction with assessing officer. Conducted entirely through portal.
Timeline.
The scrutiny process.
Important: Get a CA involved. Scrutiny assessments require professional expertise. The stakes (tax + interest + penalty) can be substantial. Don't navigate this alone.
Your rights during scrutiny.
Sections 143(2), 142(1), 144 of Income Tax Act 1961; CBDT faceless assessment scheme.
Section 148 allows the IT Department to reopen old returns if they have reason to believe income escaped assessment.
The new reassessment framework (post Finance Act 2021).
Before issuing 148. AO must:
This procedural protection prevents arbitrary reopening. AO can't just send a 148 notice — they must first conduct preliminary inquiry and give you chance to explain.
What to do on receipt.
Sections 148, 148A of Income Tax Act 1961; Finance Act 2021 reassessment amendments.
Three distinct mechanisms for correcting filed returns — each with different scope and consequences.
Sections 139(5), 139(8A), 154 of Income Tax Act 1961.
ITR-U was introduced in Finance Act 2022 to give taxpayers a one-way mechanism to disclose previously omitted income.
Key features of ITR-U.
| Aspect | Detail |
|---|---|
| Time Limit | 4 years from end of relevant AY |
| Can Be Used To | ONLY add income/pay more tax |
| Cannot Be Used To | Claim refund, reduce tax, change regime |
| Additional Tax | 25% (if within 12 months from end of relevant AY) 50% (if 12-24 months) 60% (if 24-36 months) — proposed enhancement 70% (if 36-48 months) — proposed enhancement |
When ITR-U makes sense.
When ITR-U doesn't help.
Process.
Section 139(8A) of Income Tax Act 1961; Finance Act 2022 introducing ITR-U.
Filing after the original deadline but within the assessment year — belated return.
Window. Original due date (July 31 / October 31) until December 31 of relevant AY.
Late filing fee under Section 234F.
Consequences of belated filing.
Should you file belated or wait for ITR-U?
Belated (by Dec 31): Late fee + interest, but you've filed and can claim refund (if any).
ITR-U (after Dec 31): No late fee under 234F (different mechanism), but 25-50% additional tax. Cannot claim refund.
For most filers with refund or balanced position: file belated before Dec 31. For those with significant unreported income discovered later: ITR-U is the only option.
Sections 139(4), 234F of Income Tax Act 1961.
