ITR Filing Guide India 2026: Which Form, Deductions & How to File Online Step-by-Step

Why Filing ITR Matters (Even If Tax Is Zero)

Many salaried Indians think: "My employer deducts TDS, so I don't need to file ITR." This is wrong — and costly.

Reasons to file ITR even with zero tax liability:

• Required for visa applications (most countries ask for 3 years of ITR)

• Needed for home loan, car loan applications

• Claim TDS refund (if excess was deducted)

• Carry forward capital losses to offset future gains

• Proof of income for freelancers and self-employed

Deadline: July 31, 2026 for individuals (without audit)

Step 1: Choose the Right ITR Form

Most salaried employees: ITR-1 or ITR-2 (if you have mutual fund/stock gains)

Step 2: Old Tax Regime vs New Tax Regime 2026

The new tax regime is now the default. You must actively opt for the old regime if you want deductions.

New Tax Regime (Default) — 2026 Slabs

Rebate: Zero tax up to ₹12 Lakh income under new regime (Section 87A rebate)

Standard deduction: ₹75,000 under new regime

Old Tax Regime — When It's Better

The old regime is better if your total deductions exceed:

• ₹1.5 Lakh (80C) + ₹50,000 (NPS) + ₹25,000 (health insurance) + HRA + home loan interest

Quick rule: If your deductions exceed ₹3–4 Lakh, old regime likely saves more tax.

Step 3: Gather Your Documents

Essential documents:

• Form 16 (from employer — issued by June 15)

• Form 26AS (tax credit statement — download from IT portal)

• AIS (Annual Information Statement — new, comprehensive)

• Bank statements (for interest income)

• Capital gains statement (from broker — Zerodha, Groww, etc.)

• Rent receipts (if claiming HRA)

• Investment proofs (80C, 80D, NPS)

Step 4: Key Deductions Under Old Regime

Common ITR Filing Mistakes to Avoid

Not reporting all income — Interest from savings accounts, FDs, capital gains must be reported

Wrong ITR form — Using ITR-1 when you have capital gains (should be ITR-2)

Not verifying after filing — ITR is invalid until e-verified

Missing the deadline — Late filing fee: ₹5,000 (₹1,000 if income below ₹5 Lakh)

Not reconciling with AIS — The IT department has all your transaction data. Discrepancies trigger notices.
