ITR Filing Guide FY 2025-26 (AY 2026-27): Form Selection, AIS Reconciliation, and Step-by-Step E-Filing

Every year between May and July, over 7 crore Indian taxpayers visit the official Income Tax e-Filing portal (incometax.gov.in) to submit their annual returns.

However, with increasing automation from the Project Insight AI compliance engine, the Income Tax Department automatically cross-references your reported income with bank high-value transactions, mutual fund investments, Demat sales, and credit card spends recorded in your Annual Information Statement (AIS).

A simple mistake—such as failing to report savings bank interest or picking the wrong ITR form—can trigger automated computerized scrutiny notices.

Here is a step-by-step, practitioner's guide to flawlessly filing your ITR for FY 2025-26 (AY 2026-27).

1. Step 1: Choosing the Exact Right ITR Form

Filing the wrong form is the #1 reason for Section 139(9) Defective Return notices. Use this decision table:

ITR Form	Who Must File	Who CANNOT File This Form
ITR-1 (SAHAJ)	Resident individuals with Total Income up to ₹50 Lakhs from: Salary/Pension, 1 House Property, and Other Sources (Interest/Dividends).	❌ Anyone with Capital Gains (Stocks/MFs), Directorship in a company, Unlisted Equity, or Foreign Assets.
ITR-2	Individuals and HUFs having income from Capital Gains (Mutual Funds, Stocks, Real Estate, Crypto), multiple house properties, or foreign assets/RSUs.	❌ Anyone having Income from Business or Profession (Proprietorships, Freelance 44ADA).
ITR-3	Individuals and HUFs having Business or Professional Income (Full-time traders, consultants, doctors, lawyers, agency owners).	❌ Pure salaried employees with zero freelance/business earnings.
ITR-4 (SUGAM)	Small businesses and professionals opting for the Presumptive Taxation Scheme (Section 44AD, 44ADA, 44AE) with turnover up to ₹2–3 Crore.	❌ Individuals with capital gains or turnover exceeding statutory thresholds.

Crucial Rule for Equity Investors: If you sold even 1 share of stock or 1 unit of a Mutual Fund 
during the financial year, you CANNOT file ITR-1. You must file ITR-2!

2. Step 2: The Mandatory Pre-Filing Reconciliation (AIS, TIS & 26AS)

Before typing a single rupee into the tax portal, download your three foundational tax documents:

[ THE PRE-FILING TRIANGLE ]

           1. Form 16 (Part A & Part B)
                 (Issued by your employer)
                           │
         ┌─────────────────┴─────────────────┐
         ▼                                   ▼
2. Form 26AS (TDS Ledger)          3. Annual Information Statement (AIS)
   • Tax Deducted at Source (TDS)     • All Bank Savings Interest
   • Tax Collected at Source (TCS)    • Mutual Fund Redemptions & SFTs
   • Advance Tax / Self-Assessment    • Stock Dividends & Off-Market Trades

How to Resolve Discrepancies:

If your AIS shows an erroneous transaction (e.g., a duplicated bank transaction or an investment that does not belong to you), click Feedback directly on the AIS portal tab and select "Information is denied / duplicate". The department will automatically adjust the reporting score.

3. Step 3: Capital Gains Reporting (LTCG & STCG)

For investors filing ITR-2, capital gains must be entered under Schedule CG:

1. Short-Term Capital Gains (STCG Section 111A): Listed shares and equity mutual funds held for less than 12 months are taxed at a flat 20%.
2. Long-Term Capital Gains (LTCG Section 112A): Listed shares and equity funds held for more than 12 months are taxed at a flat 12.5% on gains exceeding the ₹1,25,000 annual exemption limit.

Pro Tip: Most major Indian brokerages (Zerodha, Groww, Upstox, Angel One) provide a single "P&L Tax Filing JSON / Excel Report" that can be directly imported into third-party tax software to auto-populate Schedule CG in seconds.

5. Step 5: The 30-Day E-Verification Deadline

Submitting your ITR online is only half the job. If you do not E-Verify your return within 30 days of upload, the Income Tax Department legally treats the filing as invalid (Not Filed), resulting in late fees under Section 234F!

Fastest E-Verification Methods:

• Aadhaar OTP: (Instant 6-digit OTP sent to your Aadhaar-linked mobile number).
• Electronic Verification Code (EVC) via Net Banking: (Log in to SBI, HDFC, or ICICI NetBanking $\rightarrow$ Click 'e-Verify ITR').
• Demat Account EVC: (Generated via your verified CDSL/NSDL Demat profile).
