How to file your ITR online — without the panic

Which ITR form applies to you

India has seven ITR forms. Choosing the wrong one is the single biggest reason returns are rejected or trigger notices. The form depends on your income type, not your job title.

Decision shortcut

• Only salary + bank interest, no investments sold: ITR-1.
• Salary + sold mutual funds / stocks / property this year: ITR-2.
• Freelancer, consultant, small shop, doctor (own practice): ITR-3 (or ITR-4 if presumptive).
• Two house properties or rented one out: ITR-2 minimum.
• Holding US stocks (RSUs, vested shares), foreign bank account: ITR-2 with Schedule FA.

Documents checklist — gather these before you start

Don't open the portal first and scramble for documents mid-form. The session times out, and you lose progress. Print this list, tick everything, then file.

Identity & access

Income proof

Deduction proof (only if claiming under old regime)

Step-by-step on the income tax portal — exactly what you'll see

The official portal is incometax.gov.in. Don't pay anyone — the portal is free, official, and (in 2026) genuinely usable. The walkthrough below is screen-by-screen as the portal looks today, with insider tips no one tells you. This works for ITR-1, ITR-2, and ITR-4 — covers ~98% of salaried + freelancer cases.

Total time: 25–35 min for ITR-1 (salaried, simple). 50–70 min for ITR-2 (with capital gains). Block one quiet hour, keep your phone with you (for OTPs), keep all documents in one folder.

1. Make sure your Aadhaar–PAN link is active

   Go to incometax.gov.in → on the homepage left side, click "Link Aadhaar Status". Enter your PAN + Aadhaar. Status should say "Your PAN is linked to Aadhaar Number XXXX-XXXX-XXXX."

   If unlinkedIf it shows "not linked", you'll have to pay ₹1,000 fee + complete linking before you can file. Without an active link your PAN is treated as inoperative — TDS gets deducted at higher rate, refunds get blocked. Don't skip this check. Why this matters firstThe whole filing flow uses Aadhaar OTP for verification. If link breaks mid-way, you'll restart everything.

2. Confirm your mobile number is updated in Aadhaar

   OTPs go to the number registered with UIDAI — not the one on your PAN, not the one on your bank account. If you changed your phone in the last 5 years and never updated Aadhaar, OTPs won't reach you.

   Quick check: visit any Aadhaar Seva Kendra OR uidai.gov.in → "Verify Email/Mobile Number" → enter Aadhaar + the mobile you currently use → if it says "verified", you're good. Don't ignoreUpdating mobile in Aadhaar takes 1–2 days at a Seva Kendra (₹50 fee). Plan accordingly — last-day filers get stuck here every year.

3. Keep these 4 documents open in browser tabs

   • Form 16 PDF (from employer email)
   • Bank interest certificate / FD statement (download from net-banking)
   • Capital gains statement (Zerodha Console / Groww / CAMS / KFintech)
   • Investment proofs you'll claim under old regime (LIC, ELSS, NPS, home loan)
   Pro tipConvert Form 16 to text form by using our Form 16 Decoder — it shows you each line item in plain English so you can quickly cross-check against the portal's pre-filled data.

4. Log in to the portal

   Go to incometax.gov.in → top right click "Login". Enter PAN in capitals (the username field is case-insensitive in 2026 portal but old habit). Tick "Please confirm your secure access message" — make sure it shows your previously chosen security image / phrase. If the image is blank or different, you may be on a phishing site — close the tab.

   You'll see: a password field + below it a link "Other ways to login". Forgot password?Click "Forgot Password" → choose "Aadhaar OTP". Skip "Bank Account / Demat / Net Banking" methods unless OTP fails. Resets in 60 seconds, no email back-and-forth. First-time user?Click "Register" on the homepage. You'll need PAN + DOB + mobile + email. Set a password; do NOT use your bank password.

5. Land on the dashboard — verify everything is current

   After login, the dashboard shows: Welcome [Your Name] in top, your PAN, latest filing status, pending actions. Look at the right sidebar — "Latest Notices" and "Pending Actions". If anything is pending (defective return, scrutiny, refund pending), resolve those first — the system may block new filing until old issues clear.

   Pending demand?If you see "Outstanding Demand" with an amount — your refund (if any) for this year will be auto-adjusted against it. Open it, check if the demand is correct; if wrong, file a rectification under "Services → Rectification" before filing this year's return.

6. Pre-validate your bank account (the #1 forgotten step)

   Top menu: "My Profile" → left sidebar → "My Bank Account". Click "+ Add Bank Account". Enter: Account Number, IFSC, Account Type (Savings / Current), Bank Name, mobile (must match Aadhaar). Click "Validate".

   Validation status: "Validation in Progress" → wait 30 sec → "Validated" (green tick) OR "Validation Failed". Refresh the page once. Refund will bounce if(a) Account is not in your name exactly as on PAN, (b) IFSC is wrong, (c) Account is dormant or closed, (d) Aadhaar mobile mismatch. Use a savings account you actively use — not an old ICICI account from college. Validate 2 accountsMark one as "Nominate for Refund". If the first one fails for any reason (some bank goes through a merger, IFSC changes), the second is a backup.

7. Pre-validate your demat / Aadhaar for e-verification (do it now, not later)

   "My Profile" → "My Bank Account" + "Demat Account" sections. Both can be used to e-verify your return at the end. Easiest method is Aadhaar OTP; demat / bank EVC is fallback.

   The trickTest your Aadhaar OTP NOW by clicking "e-Verify Other Returns" from the menu — even if you have nothing to verify, the OTP page opens. If OTP doesn't arrive, you have time to fix mobile registration before you've spent 40 minutes filling the form.

8. Download your AIS (Annual Information Statement)

   From the dashboard: top menu "Services" → "Annual Information Statement (AIS)". Wait for the page to load (sometimes 5-10 seconds). Click the AY "2026-27" tile. Then click "Download" → choose PDF + JSON (PDF for reading, JSON for searching).

   The PDF is password protected: PAN (lowercase) + DOB (DDMMYYYY). Example: PAN = ABCDE1234F, DOB = 15-Jan-1990 → password = abcde1234f15011990. AIS is gospelWhatever appears in AIS, the department knows about it. If you skip something here, expect a mismatch notice in 60 days. Reconcile EVERY entry — don't trust pre-fill blindly.

9. Read AIS section by section — what to look for

   The AIS PDF is divided into sections. Open it and check each:

   • SFT (Specified Financial Transactions): high-value transactions reported by banks/MFs — FDs > ₹10 L, MF purchases > ₹10 L, credit card spends > ₹2 L/month, foreign travel > ₹2 L. Each one needs a tax explanation (where did the money come from?).
   • TDS: tax already deducted by employer / bank / clients. Cross-match with your Form 16 / interest certificates. If TDS is shown but salary isn't full — click "Feedback" on that entry to flag.
   • TCS: tax collected at source — usually on car purchase, foreign remittance > ₹7 L.
   • Sale of securities / units: equity, MF redemptions. This drives capital gains. Match with your broker's capital gains statement.
   • Receipt of foreign remittance: RSU vests, ESPP, gifts from NRIs — ALL show up here.
   • Interest from savings / FD: bank-wise list. Add up all of them — most filers miss the ₹500 interest from an old account.
   • Dividend: from listed shares + MFs. Fully taxable as "Income from other sources".
   Found a mistake?In the AIS portal, click "Optional" next to the wrong entry → "Submit Feedback". Choose: Information is correct / Information is partially correct / Information is duplicate / Information relates to other PAN. The correction takes 7-15 days; file your return only after AIS shows updated values, otherwise you'll have to file a revised return later.

10. Download Form 26AS as a backup

    Top menu "e-File" → "Income Tax Returns" → "View Form 26AS". Portal redirects to TRACES → click "Confirm" → choose AY 2026-27, format HTML / PDF. 26AS is a subset of AIS (only TDS / TCS / advance tax / refund). AIS includes everything 26AS does + more.

    Why download bothSometimes 26AS shows a TDS entry that hasn't yet flowed into AIS (timing lag). The portal pulls pre-fill from AIS, so you may need to manually add the missing TDS in your return — keeping 26AS open helps you spot it.

11. Click "File Income Tax Return"

    Top menu "e-File" → "Income Tax Returns" → "File Income Tax Return". You land on a wizard.

    Wizard step 1: Assessment Year — pick "2026-27" (because we're filing for FY 2025-26 income).
    Wizard step 2: Filing Mode — pick "Online".
    Wizard step 3: Status — "Individual" for personal filing, "HUF" only if you have a registered Hindu Undivided Family.
    Wizard step 4: ITR form — pick 1 / 2 / 3 / 4 based on Section 1. Help me decideIf unsure, click "Help me decide which ITR Form to file" — answer 4-5 yes/no questions; portal auto-suggests. Use this even if you think you know — catches edge cases like "did you sell crypto?" you may have forgotten.

12. Choose old regime vs new regime

    You'll see a screen titled "Which tax regime do you wish to opt for?" with two cards: New Regime (default) and Old Regime. The portal silently defaults you to new regime if you don't pick.

    Decision rule: open our Income Tax Calculator in a separate tab. Enter your salary + planned deductions. Compare both regime numbers. Pick whichever shows lower tax. Difference can be ₹10,000–₹80,000. Old regime gotchaIf you're a salaried employee and you've already declared the new regime to your employer (and they deducted TDS accordingly), you can still switch to old in your return — but you'll pay extra cash via Self-Assessment Tax. The reverse: if employer used old regime but you switch to new in return, you get a refund. Both directions are allowed for salaried; not for businesses.

13. Confirm pre-filled personal details

    Next screen: "Personal Information". Pre-filled: Name, PAN, DOB, address, mobile, email, Aadhaar. Check the bank account section — your validated account from Step 6 should appear; mark it as "For Refund".

    Address tipIf you moved recently, update the address here — but it'll only update for THIS return. To change permanently in PAN database, file a separate PAN correction request after. Nature of EmploymentSalaried users: pick "Other" if you work for a private company, "Government" if you're a public servant, "PSU" if working for a public sector undertaking. Wrong choice doesn't reject the return but may flag for manual review.

14. Review pre-filled income — line by line

    Next: "Gross Total Income". Portal pre-fills five buckets from AIS / 26AS:

    • Salary — must match Form 16 Part B "Gross salary".
    • House Property — rental income, less municipal tax + 30% standard deduction + home loan interest.
    • Capital Gains — STCG, LTCG, intra-day, F&O.
    • Business / Profession — only in ITR-3 / ITR-4.
    • Other Sources — savings interest, FD interest, dividends, gift income.
    The most common error herePre-filled salary is OFTEN wrong by ₹50K–₹2L because it pulls from Form 16 Part A (TDS only) but misses non-TDS allowances. Always edit it to match Form 16 Part B's "Gross salary" manually. Use the small "edit pencil" icon next to each line. Click the magnifying glassNext to each pre-filled value there's a 🔍 icon — click it to see which document the system pulled the value from (AIS / Form 16 / 26AS). Helpful when you're not sure where a number came from.

15. Add capital gains (ITR-2 / ITR-3 only)

    Click "Schedule CG". You'll see sub-sections: Equity (STT paid), Equity without STT, Slump sale, Property, Bonds & debentures, etc.

    For each scrip / fund sold, enter:
    • ISIN code (look up in Zerodha Console / CDSL statement if missing)
    • Number of units
    • Date of acquisition (DD/MM/YYYY)
    • Cost of acquisition
    • Date of transfer (sale)
    • Sale value
    • STT paid (Yes/No — yes for listed equity)
    • For LTCG: Cost as per FMV on 31 Jan 2018 (grandfathering rule for shares bought before that) Bulk entry hackThe portal has a "Add Multiple Rows" link below the table — click it, choose how many rows to add at once (max 100). Saves clicking "Add" 50 times. Excel paste-into doesn't work, but tabbing through fields is fast once you have the broker statement open side-by-side. The grandfathering trapFor equity acquired BEFORE 31 Jan 2018, LTCG is calculated using the higher of (actual cost) or (FMV on 31 Jan 2018). Most filers forget this and overpay tax. Zerodha / Groww auto-calculate this in their statements; just copy. F&O / intra-dayF&O profit is business income (not capital gains) — switch to ITR-3, declare under "Income from Business" Schedule BP. Intra-day equity is speculative business income — also Schedule BP, separately.

16. Claim deductions (old regime only — Schedule VI-A)

    If you picked old regime, you'll see "Schedule VI-A — Deductions". Enter each section's amount:

    • 80C (max ₹1.5 L): EPF + PPF + ELSS + LIC + kids' tuition + home loan principal + Sukanya Samriddhi
    • 80CCD(1B) (max ₹50,000): NPS additional contribution — extra over 80C
    • 80D: health insurance — self/family ₹25,000 (₹50,000 if senior citizen) + parents ₹50,000 if senior
    • 80E: education loan interest — no cap, deductible for 8 years
    • 80G: donations — 50% / 100% based on the registered entity
    • 80TTA / 80TTB: savings interest deduction — ₹10,000 / ₹50,000 for seniors
    • Section 24(b) (in House Property schedule, not VI-A): home loan interest up to ₹2 L for self-occupied
    Don't fake itThe system cross-checks 80C with EPFO + LIC + AMC databases, 80D with insurer filings, 80G with charity records (Form 10BD). False claim = 200% penalty + Section 270A prosecution. Claim only what you have receipts for. HRA — separatelyHRA isn't in Schedule VI-A — it's in the Salary schedule. The portal asks: "Did you pay rent during the year?" Answer Yes → enter rent paid + landlord PAN (if rent > ₹1 L/year) + place of work + HRA received from employer. The system computes the deductible amount.

17. Verify the final tax computation

    Click "Confirm" → "Tax Computation". You'll see a summary table:

    • Gross Total Income
    • Total Deductions (only if old regime)
    • Taxable Income
    • Tax @ slab rates (auto-computed)
    • Surcharge (if income > ₹50 L)
    • Health & Education Cess (4% on tax + surcharge)
    • Total Tax Payable
    • Less: TDS / TCS / Advance Tax
    • Refund OR Balance Tax Payable
    Compare with Form 16The "Total Tax Payable" on the portal should be roughly equal to Form 16's "tax payable on income" line. Difference is fine if you added bank interest / capital gains your employer didn't know about. If balance tax is payableYou owe extra tax. Pay it BEFORE submitting return — click "Pay Now", fill challan ITNS-280 → choose "Self Assessment Tax (300)" → AY 2026-27 → pay via net banking or UPI. After payment, the BSR code + CIN come back. Wait 24 hours for the payment to reflect in the portal, then add it under "Tax Paid" schedule, then re-validate.

18. Preview the entire return

    Click "Preview Return". The portal generates a one-page summary PDF — review it once. Check: name, PAN, AY, ITR form type, all 5 income heads, deductions, tax computation, refund / balance tax. If anything looks off, click "Edit" and go back.

    Save a copyRight-click the preview PDF → "Save as" → keep it as ITR_AY2026-27_FY2025-26.pdf. This is your record. The portal also stores it under "Filed Returns" but local copy is best for years 7+ (portal sometimes retires older returns from active view).

19. Submit the return

    Click "Submit" at the bottom. Confirmation modal appears: "Are you sure you want to submit?" — click "Yes". The portal generates an Acknowledgement Number (ITR-V). Note it down. Status now: "Submitted but not e-verified".

    Submitted ≠ FiledThis is the most-missed step in Indian tax filing. Until you e-verify, your return is INCOMPLETE. After 30 days without verification, the return becomes invalid — treated as not filed at all. You'll have to file fresh + pay late filing penalty.

20. e-Verify — the 60-second finishing move

    Right after submitting, the next screen shows "e-Verify Now". Click it. Choose method:

    • Aadhaar OTP (recommended) — 60 seconds. OTP comes to Aadhaar-linked mobile. Enter, click submit. Done.
    • Net Banking EVC — log into your bank's net banking, find "e-Verify Income Tax Return" link. 2 mins.
    • Bank Account EVC — generates a 10-digit code via your validated bank account. Enter on portal.
    • Demat Account EVC — same, but via demat. Useful if other methods fail.
    • Send signed ITR-V by post — print, sign in BLUE ink, post to "CPC Bengaluru, Income Tax Department, Post Bag 1, Electronic City Post Office, Bengaluru 560100". Takes 7-15 days. Avoid unless nothing else works — if post is lost, no proof.
    After successful e-verification: status changes to "Successfully e-Verified" with timestamp. Email confirmation arrives in 5 minutes. Aadhaar OTP not arriving?Wait 60 seconds, click "Resend OTP". If still not coming: confirm Aadhaar mobile is active, you have signal, you're not on DND for govt SMS. Worst case: switch to net banking EVC, every major bank supports it (HDFC, ICICI, SBI, Axis, Kotak — all have an "Income Tax e-Verify" link inside net banking).

21. Confirm your filing — the proof you need

    Top menu "e-File" → "Income Tax Returns" → "View Filed Returns". Your latest return appears with status "Successfully e-Verified". Click "Download Receipt" → you get a PDF (ITR-V) with your acknowledgement number, filing date, e-verification timestamp.

    Save 3 things forever(a) The submitted ITR PDF, (b) The ITR-V acknowledgement, (c) The Form 16 + AIS that backed it up. Income tax can ask for verification up to 7 years later (10 years if foreign assets). Keep all 3 in cloud + local backup.

Mistakes that trigger notices (and how to avoid each)

The Income Tax department has gone full algorithmic — most mismatches are auto-flagged within 60 days of filing and result in a Section 143(1) intimation or worse, a Section 139(9) defective return notice. These are the most common traps.

1. Choosing the wrong ITR form

Filing ITR-1 with even ₹500 of capital gains makes the return defective under Section 139(9). You'll get 15 days to fix and re-file. Fix: use the decision shortcut in Section 1. When in doubt, file ITR-2 — it's a superset of ITR-1.

2. Ignoring AIS mismatches

If AIS shows a ₹1.2 lakh dividend and you reported ₹80,000, the system flags it. Fix: always reconcile AIS before filing. If AIS itself is wrong (broker reported wrong figure), submit feedback in AIS portal first; the corrected version flows into your return.

3. Forgetting bank interest

Savings account interest, FD interest, RD interest — all taxable (savings interest gets ₹10,000 deduction under 80TTA / ₹50,000 under 80TTB for seniors). Banks report these in Form 26AS even when no TDS is deducted. Fix: add up interest from every bank account, including the ones you forgot you opened.

4. Wrong capital gains classification

Equity held > 12 months = LTCG (10% above ₹1 lakh). Held ≤ 12 months = STCG (15%). Property: 24 months threshold. Debt funds: full slab rate from FY 2023-24 onwards. Fix: trust your broker's capital gains statement — it auto-classifies.

5. HRA without rent receipts

Old regime only. If you claim HRA but tenant database doesn't show your landlord's PAN reporting your rent as income, you may get a Section 133(6) inquiry. Fix: only claim HRA you genuinely paid; collect physical rent receipts; landlord PAN required if rent > ₹1 lakh/year.

6. Claiming 80C beyond ₹1.5 lakh

EPF + PPF + ELSS + LIC + kids' tuition + home loan principal combined cap is ₹1.5 lakh. Filing ₹1.7 lakh worth of receipts won't give extra deduction; system caps it automatically but flags as careless. Fix: add up your 80C investments before claiming.

7. Missing foreign assets schedule (Schedule FA)

Vested US RSUs, ESPP, foreign bank account, crypto on foreign exchange — all must be disclosed in Schedule FA in ITR-2 / ITR-3. Non-disclosure = ₹10 lakh fine + prosecution under Black Money Act. Fix: always file ITR-2 if you have any foreign asset, no matter how small.

8. Not e-verifying within 30 days

Return submitted but not e-verified = treated as not filed. Late e-verification (after 30 days) attracts Section 234F late fee. Fix: e-verify within 5 minutes of submitting via Aadhaar OTP.

9. Wrong bank account for refund

Refund credited to a closed / dormant account = bounces, then portal locks the refund pending re-validation. Fix: mark your active primary account as "preferred" on the portal under My Bank Account.

10. Filing after due date

Belated return (after 31 July, before 31 December) = ₹5,000 fee under Section 234F (₹1,000 if income < ₹5 lakh) + interest under 234A on unpaid tax + you lose the right to carry forward losses. Fix: file by 31 July even if you don't have all data — you can revise later.

Track your refund — what to expect, when to worry

Refund is processed only after Section 143(1) intimation is generated. Expect 15-45 days from e-verification for most simple returns; 60-120 days if your return triggers manual review.

How to check status

1. Log in to incometax.gov.in
2. Go to Services → Know Your Refund Status
3. Enter PAN and Assessment Year (2026-27 for current filing)
4. Status appears: "Refund Issued", "Refund Failed", "No Demand No Refund", "Refund Pending Verification"

Alternative — TIN-NSDL portal

Older but reliable: tin.nsdl.com → Refund Status → enter PAN + AY. No login required.

What each status means

When to escalate

• > 60 days since e-verification, no intimation: raise a grievance under "e-Nivaran" on the portal.
• Refund failed twice: contact the Centralised Processing Centre (CPC) Bengaluru via the contact us section.
• Refund "issued" but bank not credited after 7 days: check with bank first, then raise grievance.

Deadlines, penalties, and the late-filing math

Late filing fee — Section 234F

• Total income ≤ ₹5 lakh: ₹1,000
• Total income > ₹5 lakh: ₹5,000

Interest — three sections

• 234A — 1% per month on tax payable, from 1 August till date of filing.
• 234B — 1% per month if you hadn't paid 90% of tax via TDS / advance tax by 31 March.
• 234C — 1% per month for missing advance tax instalments (15 June, 15 Sep, 15 Dec, 15 Mar).

Combined, late filing on a moderate refund-due return adds up to a few thousand rupees easily. File on time.

Frequently asked questions

Can I file ITR myself or do I need a CA?

For salaried, single-employer, simple capital gains cases — file yourself. The portal is friendly enough and a CA charges ₹1,000-3,000 for what is genuinely a 30-minute job. Hire a CA if: business income with audit, ESOPs / RSUs across multiple countries, scrutiny notice received, restructuring (like sale of long-held property).

I switched jobs mid-year. How do I file?

You'll have two Form 16s. Tell the second employer about the first (Form 12B) so they deduct tax correctly — most don't, leading to under-deduction. At filing time, add both employers' salary + TDS in the "Salary" schedule. The portal allows multiple employers.

I forgot to declare ₹X to my employer — can I still claim deductions?

Yes. Old regime: claim 80C / 80D / HRA / home loan etc. directly in your ITR even if you didn't tell your employer. The TDS will be higher than required, but you'll get the excess back as refund.

Is the new regime always better?

No. New regime wins if your total deductions are below ~₹3.75 lakh (rough thumb-rule for salary + 80C + standard deduction; varies with slab). Old regime wins if you have heavy HRA + 80C + home loan interest + 80D combined. Always run both through a calculator.

I have crypto profits — what to file?

Crypto profits = "Income from Virtual Digital Assets" — flat 30% tax + 1% TDS already deducted by Indian exchanges. Reported in Schedule VDA (in ITR-2 / ITR-3). Losses can't be set off against any other income or carried forward.

I'm an NRI — which form?

ITR-2 (most cases). You report only India-sourced income. Foreign income is taxed in country of residence. India still taxes: rent from Indian property, capital gains on Indian shares, NRO interest. Submit Schedule FA only if you became Resident again during the year.

Can I claim home loan interest if I don't live in the property?

Yes. "Let-out" or "deemed let-out" property: full home loan interest deductible against rental income (with no ₹2 lakh cap from FY 2023-24 if old regime). New regime: home loan interest deduction is restricted, run the numbers carefully.

What's the difference between revised and updated return?

Revised return (Sec 139(5)): file by 31 December — fix any mistakes, can result in lower tax / higher refund. Updated return (ITR-U, Sec 139(8A)): file within 2 years of AY end — can ONLY add income that wasn't disclosed earlier, attracting 25% / 50% additional tax depending on timing. Use revised when possible.
