How to File ITR Online in India 2026 — Complete Step-by-Step Guide for Salaried Individuals
File ITR Online in India
2026 — New Law. Simple Guide.
India’s Income Tax Act 1961 is replaced by the New Direct Tax Code from April 1, 2026. Here is everything that changed — and your complete step-by-step filing guide.
I have filed over 200 returns personally and advised hundreds more. Every year, the same confusion, the same mistakes, the same panicked messages in July. But this year is genuinely different. India switched to the New Direct Tax Code (Income Tax Bill 2025) on April 1, 2026, replacing the Income Tax Act 1961 which had stood for 65 years. The terminology changed. Some numbering changed. The process, however, is simpler than ever. This guide covers everything — old law to new law — so you file confidently before July 31.
1. Old vs New Terminology — Know This First
If you have filed ITR before, the terminology will feel unfamiliar. Here is the complete translation. The underlying concepts are identical — only the names changed.
| Old Term (Income Tax Act 1961) | New Term (Direct Tax Code 2026) | Meaning |
|---|---|---|
| Previous Year (PY) | Tax Year | Year in which income is earned (April–March) |
| Assessment Year (AY) | Tax Year (same) | No longer a separate concept — eliminated |
| AY 2026–27 | Tax Year 2025–26 | For income earned April 2025–March 2026 |
| Section 87A (Rebate) | Rebate under new schedule | Same benefit, renumbered section |
| Section 80C, 80D | Not applicable (new regime) | Still exist in old regime option |
| Assessee | Taxpayer | Same meaning, simpler word |
| Return of Income | Tax Return | Same document, cleaner name |
When you file your ITR in 2026, select “Tax Year 2025–26” on the portal — not “AY 2026–27”. The Income Tax Portal has been updated to reflect new DTC terminology. If you see “Assessment Year” anywhere, it refers to the old system and may appear in legacy documents only.
“The new Direct Tax Code does not change how much tax you pay. It changes how clearly you understand it. That alone is worth celebrating after 65 years of legal ambiguity.”

2. Who Must File? Eligibility Under New DTC
- Gross income exceeds Rs.2.5L (old regime) or Rs.3L (new regime)
- TDS deducted from salary and you want a refund
- Deposits exceeding Rs.1 crore in bank accounts in the Tax Year
- Electricity bills exceeding Rs.1 lakh in the Tax Year
- Foreign travel expenses exceeding Rs.2 lakh
- You have foreign assets or income from foreign sources
Even if your income is below the taxable limit — always file if TDS was deducted. Under the new DTC, the portal auto-populates TDS data from employers and banks. Not filing means you forfeit the refund permanently after the deadline.
3. Which ITR Form? (Updated for DTC 2026)
The form names remain the same under the new DTC. The rules for choosing the right form are unchanged. Here is the decision in plain language:
- Salary or pension income only
- Total income up to Rs.50 lakh
- ONE house property
- Other sources (FD, savings interest)
- Agricultural income up to Rs.5,000
- Any capital gains (stocks, MF, property)
- More than one house property
- Foreign income or assets
- Income above Rs.50 lakh
- Brought forward losses to claim
- Under new DTC, incorrect form selection triggers an automated defective return notice within 15 days — faster than before. Choose carefully.
- Even a single ELSS redemption in Tax Year 2025–26 = capital gain = ITR–2 mandatory.
4. New Regime vs Old Regime — 2026 Slabs
Under the new DTC, the new tax regime is the permanent default. You must explicitly opt into the old regime if you want deductions like 80C, HRA, and 80D. Here are the exact slabs for Tax Year 2025–26:
New Regime Slabs — Tax Year 2025–26
| Taxable Income | Rate | Max Tax on Slab |
|---|---|---|
| Up to Rs.4,00,000 | 0% | Nil |
| Rs.4,00,001 – Rs.8,00,000 | 5% | Rs.20,000 |
| Rs.8,00,001 – Rs.12,00,000 | 10% | Rs.40,000 |
| Rs.12,00,001 – Rs.16,00,000 | 15% | Rs.60,000 |
| Rs.16,00,001 – Rs.20,00,000 | 20% | Rs.80,000 |
| Rs.20,00,001 – Rs.24,00,000 | 25% | Rs.1,00,000 |
| Above Rs.24,00,000 | 30% | 30% of excess |
| Benefit | New Regime | Old Regime |
|---|---|---|
| Standard Deduction | Rs.75,000 | Rs.50,000 |
| Rebate (zero tax up to) | Rs.12,00,000 income | Rs.5,00,000 income |
| Max Rebate Amount | Rs.60,000 | Rs.12,500 |
| Section 80C | ✗ Not available | ✓ Up to Rs.1,50,000 |
| Section 80D (Health) | ✗ Not available | ✓ Up to Rs.25,000 |
| HRA Exemption | ✗ Not available | ✓ Applicable |
| Home Loan Interest (24b) | ✗ Not available | ✓ Up to Rs.2,00,000 |
| Default under DTC 2026 | ✓ YES — automatic | Must opt in explicitly |

5. Real Example: Rs.8 Lakh Salary — Complete Calculation
Let me walk through Priya’s case — a software analyst in Bhubaneswar earning Rs.8 lakh gross salary in Tax Year 2025–26. Her employer deducted TDS under the new regime. Here is the exact math:
| Step | New Regime (DTC) | Old Regime |
|---|---|---|
| Gross Salary | Rs.8,00,000 | Rs.8,00,000 |
| Standard Deduction | − Rs.75,000 | − Rs.50,000 |
| 80C (PPF+ELSS) | Not allowed | − Rs.1,50,000 |
| 80D (Health Ins.) | Not allowed | − Rs.25,000 |
| Taxable Income | Rs.7,25,000 | Rs.4,75,000 |
| Tax on Income | Rs.16,250 | Rs.11,250 |
| Rebate (87A equivalent) | − Rs.16,250 (full) | − Rs.11,250 (full) |
| 4% Health & Education Cess | Rs.0 | Rs.0 |
| FINAL TAX | Rs.0 🎉 | Rs.0 🎉 |
Zero tax under both regimes. The new regime wins on simplicity — no investment proof, no form filing for deductions, same result. Priya saves Rs.0 in tax AND saves the effort of 80C investment paperwork. Under DTC 2026, the new regime is automatically applied — she does not need to do anything extra.
6. Step-by-Step: File on incometax.gov.in (DTC Portal)
Open incometax.gov.in. The portal has been updated for the new DTC. You will now see “Tax Year” instead of “Assessment Year” in the filing workflow.
Before touching any form: go to My Profile → Bank Account → Add → Pre-validate. This is mandatory for refund. A pre-validated account receives refunds in as little as 7 days. Without it, your refund waits indefinitely regardless of ITR processing.
Under DTC, your Annual Information Statement (AIS) is now even more comprehensive — it includes salary, TDS, interest income, dividends, mutual fund transactions, and property purchases. Download it from e-File → Income Tax Returns → View AIS. Cross-check every figure with your own records before proceeding.
Select Tax Year 2025–26 (this is what was previously called AY 2026–27). Choose mode: Online. Choose form: ITR–1 for most salaried. The portal pre-fills salary, TDS, and interest data from your AIS and Form 16 automatically. Do not skip verification of these figures.
Verify: Salary matches Form 16 Part B, TDS matches Form 26AS, bank interest matches AIS. Add anything missing: freelance income, rental income, post office interest. Under DTC, the portal flags any discrepancy between your entry and AIS automatically.
The portal defaults to new regime. To use old regime, click “Opt for Old Tax Regime” and enter your deductions (80C, 80D, HRA). The portal will show your tax under both and let you choose. This choice is final once submitted.
If the summary shows Refund — congratulations, just proceed. If it shows Tax Due, pay via e-Pay Tax → Self-Assessment Tax (Code 300) via UPI or net banking. Enter challan details in the return. Never submit with unpaid tax due.
After submission, e-verify using Aadhaar OTP (fastest — 60 seconds). Alternative: Net Banking EVC or Demat account. An unverified return is legally treated as not filed. You will lose your refund claim and face penalty. Do not delay verification even by a day.
7. Documents Checklist
- Form 16 Part A & B — from employer by June 15, 2026 (old name — valid for Tax Year 2025–26 filing; becomes Form 130 from next year)
- Form 26AS (Form 168 from next year) — download from incometax.gov.in → e-File → Income Tax Returns → View AIS
- Annual Information Statement (AIS) — check all entries
- PAN Card — must be linked with Aadhaar (mandatory)
- Aadhaar-linked mobile — needed for OTP e-verification
- Bank Account — pre-validated on portal for refund credit
- Savings/FD Interest Statement — from bank (full Tax Year)
- Investment Proof — 80C (PPF, ELSS, LIC) — old regime only
- Health Insurance Premium — 80D receipt — old regime only
- Home Loan Certificate — interest certificate — old regime only
- Rent Receipts / Landlord PAN — HRA claim — old regime only
- Form 15G / Form 15H / Form 121 — if submitted to bank to avoid TDS on FD interest (15G/15H valid this cycle; Form 121 from April 2026)
- Capital Gains Statement — from broker/CAMS if you traded in Tax Year
8. 5 Mistakes That Trigger Notices Under DTC 2026
The new DTC comes with an enhanced automated scrutiny system. These mistakes now trigger faster notices — often within 15 days of filing instead of the months it previously took.
The AIS now captures every interest credit from every bank, post office, and NBFC. Under the new DTC, mismatches between your return and AIS trigger an automated Section 143(1)(a) notice. The department knows your FD interest before you do.
Under the new DTC portal, “Tax Year 2025–26” is what you select — not “AY 2026–27.” Several people selecting “Tax Year 2024–25” by mistake are filing for the wrong year. Check the year carefully before proceeding past the first screen.
Any mutual fund redemption, stock sale, or ELSS exit in Tax Year 2025–26 creates a capital gain entry in your AIS. The system cross-checks this. Filing ITR–1 with capital gains in AIS = defective return notice within 15 days.
The refund is processed to your pre-validated account. If no pre-validated account exists, CPC holds the refund. I have seen people wait 10 months for a Rs.8,000 refund because of this single omission. Under new DTC, this step is now highlighted on the portal dashboard but still skipped by thousands.
A filed-but-unverified ITR is legally nonexistent under both old law and new DTC. Your refund is forfeited. The late filing penalty clock does not reset. I see this every year from people who file in June, get distracted, and forget to verify until August.
- After July 31, 2026 (belated return): Rs.5,000 penalty (Rs.1,000 if income below Rs.5 lakh)
- After December 31, 2026: Filing only with department notice, heavy interest under new DTC provisions
- Deliberate non-filing: Prosecution provisions strengthened under new DTC
9. Refund Timeline — Verified Under DTC 2026
The new DTC comes with a statutory refund processing timeline built into the law — something the old Income Tax Act lacked. Here is the updated verified timeline:

2. Every Form You Know — New Names Under DTC 2026
This is the section most blogs get wrong. Let me be very precise here because the timeline matters enormously for how you file this year.
Old forms still apply for your July 2026 filing. The Income Tax Act 2025 and Rules 2026 are effective from April 1, 2026 — but they apply to Tax Year 2026–27 onwards (income earned from April 1, 2026). For the ITR you file by July 31, 2026 (covering income from April 2025 to March 2026), your employer will still issue Form 16, and you will still download Form 26AS. The new form numbers (Form 130, Form 168) become active from next year's filing cycle.
Complete Form Renaming Table — Old vs New
| Old Form (IT Act 1961) | New Form (DTC 2026) | Purpose | Active From |
|---|---|---|---|
| Form 16 | Form 130 | TDS certificate for salaried employees & pensioners | Tax Year 2026–27 |
| Form 16A | Form 131 | TDS certificate for non-salary income (bank interest, rent, commission) | Tax Year 2026–27 |
| Form 26AS | Form 168 | Annual Information Statement (AIS) — all income & TDS data linked to PAN | Tax Year 2026–27 |
| Form 15G + Form 15H | Form 121 (merged) | Declaration to avoid TDS on interest — now single form for all ages | April 1, 2026 |
| Form 12BB | Form 124 | Investment declaration submitted to employer for TDS calculation | Tax Year 2026–27 |
| Forms 3CA + 3CB + 3CD | Form 26 (consolidated) | Tax audit report — all three merged into one | Tax Year 2026–27 |
| Forms 24Q + 26Q | Forms 138 + 140 | TDS return forms filed by employers/deductors | Tax Year 2026–27 |
- Effective immediately from April 1, 2026 — this change applies NOW, not next year.
- Previously: Senior citizens (60+) used Form 15H. Others used Form 15G. Two different forms, same purpose.
- From April 1, 2026: Both are replaced by a single Form 121 for all ages. Less confusion, less paperwork.
- Purpose unchanged: Submit to your bank to avoid TDS deduction on FD/savings interest when income is below taxable limit.
- If you submitted Form 15G or 15H to your bank before April 1, 2026, those remain valid for the remainder of Tax Year 2025–26.
Other Important Form Changes You Should Know
| Change | Detail | Impact on You |
|---|---|---|
| Form 12BB → Form 124 | Investment declaration to employer | Submit Form 124 to your employer from FY 2026–27 for TDS calculation |
| Forms 3CA+3CB+3CD → Form 26 | Tax audit consolidated into one form | Relevant only if your CA files audit reports — not for individual salaried |
| HRA exemption cities expanded | 4 new cities added: Bengaluru, Pune, Hyderabad, Ahmedabad | 50% HRA exemption now covers 8 cities — check if your city qualifies |
| Meal voucher limit | Tax-free limit raised from Rs.50/meal to Rs.200/meal | If employer provides meal cards, Rs.200/meal now tax-free under both regimes |
| Children education allowance | Rs.100/month → Rs.3,000/month per child | Claim in old regime only — 30x increase from previous limit |
| Gift voucher limit | Rs.5,000/year → Rs.15,000/year | Now available under BOTH regimes — 3x increase |
| ITR-3 / ITR-4 deadline | Extended from July 31 to August 31 | One extra month for business owners, freelancers, and professionals |
Use this simple rule: Income earned in FY 2025–26 (April 2025 – March 2026) = filed using old form names (Form 16, Form 26AS). Income earned from April 1, 2026 onwards (Tax Year 2026–27) = filed next year using new form names (Form 130, Form 168). The portal handles this automatically — just always verify the Tax Year shown on every document before proceeding.
New Law. Simple Filing. Zero Confusion.
The new Direct Tax Code is India’s biggest tax reform in 65 years. But for salaried employees like you, the process is the same — just cleaner. Use the checklist, follow the 7 steps, avoid the 5 mistakes, and file before July 31, 2026.
