How to File Investment Tax Returns in India (FY 2025–26) Complete Documentation & Compliance Guide

Key Takeaways

  • LTCG on listed equity taxed at 12.5% above ₹1.25 lakh exemption.

  • Correct ITR selection (mostly ITR-2 for investors) is crucial.

  • Always reconcile capital gains with AIS before filing.

  • Maintain documentation for minimum 7 years.

  • E-verification within 30 days is mandatory to validate return.

A few years ago, a young IT professional from Mumbai made substantial profits from stock market investments. He was confident about his trading strategy but casual about compliance. “My broker has all the records,” he thought.

Months later, he received a notice due to a mismatch in his Annual Information Statement (AIS). The issue wasn’t tax evasion  it was incorrect reporting.

That incident reinforced what I have advised investors for over 25 years:

“Investment success is measured not only by returns, but by how well you manage compliance.”

Let us now address the most common questions investors ask me during tax season.

What income from investments is taxable in India?

LTCG 12.5% India

Any profit arising from sale of shares, mutual funds, property, bonds, or other capital assets is taxable under the head Capital Gains. Interest from fixed deposits, savings accounts, and bonds is taxable under Income from Other Sources. Dividend income is also taxable at slab rates in the hands of the investor.

How are capital gains taxed currently?

For FY 2025–26:

  • Short-Term Capital Gains (STCG) on listed equity (held less than 12 months) are taxed at 20%.

  • Long-Term Capital Gains (LTCG) on listed equity (held more than 12 months) are taxed at 12.5%, applicable only on gains exceeding ₹1.25 lakh annually.

  • Property held less than 24 months is treated as short-term and taxed at slab rates.

  • Property held beyond 24 months qualifies as long-term and taxed at 12.5%, with exemption options under Sections 54 and 54EC.

Even if your LTCG is below ₹1.25 lakh and no tax is payable, reporting it in ITR is mandatory.

Which ITR form should an investor file?

Most salaried investors with capital gains should file ITR-2.

ITR-1 cannot be used if you have significant capital gains. If you have business income along with investments, then ITR-3 is applicable.

Filing the wrong form is one of the most common compliance errors.

What documents are required before filing?

Before starting, keep the following ready:

  • PAN and Aadhaar

  • Form 16 (for salaried individuals)

  • AIS and Form 26AS

  • Broker’s capital gains statement

  • Consolidated Account Statement (CAMS/KFintech)

  • Bank statements

  • Property purchase/sale documents (if applicable)

  • Deduction proofs (80C, 80D, NPS, donations)

Digital copies are sufficient. Maintain records for at least 7 years.

Why is AIS reconciliation important?

AIS (Annual Information Statement) reflects all reported financial transactions  including stock sales, mutual fund redemptions, dividends, and interest income.

If your ITR does not match AIS data, the system may flag discrepancies. Always cross-check sale values, interest income, and TDS details before submission.

How to report capital gains in ITR?

Capital gains must be reported under Schedule CG in ITR-2.

You must enter:

  • ISIN of shares or fund

  • Date of purchase and sale

  • Quantity

  • Cost of acquisition

  • Sale consideration

  • Expenses (brokerage, transfer charges)

FIFO (First In First Out) method applies for equity shares and mutual funds.

Can I claim deductions while having capital gains?

Yes, but only under the Old Tax Regime.

Common deductions include:

  • Section 80C – ₹1.5 lakh (PPF, ELSS, EPF, home loan principal)

  • Section 80D – Health insurance premium

  • Section 80CCD(1B) – ₹50,000 additional NPS deduction

  • Section 80G – Donations

  • HRA exemption

Under the New Tax Regime, most deductions are not allowed, but lower slab rates and rebate benefits apply. Always calculate tax under both regimes before deciding.

What if TDS is insufficient on investment income?

If total tax liability exceeds ₹10,000 in a financial year, you must pay Advance Tax in quarterly installments.

Failure to pay advance tax leads to interest under Sections 234B and 234C.

Capital gains earned during the year must be included in your advance tax calculation.

How are losses treated in tax filing?

Short-term capital losses can be adjusted against both short-term and long-term gains.

Long-term capital losses can be adjusted only against long-term gains.

Unabsorbed losses can be carried forward for 8 years provided the return is filed within the due date.

What are common compliance mistakes investors make?

  • Not reporting exempt LTCG

  • Ignoring AIS mismatch

  • Choosing incorrect ITR form

  • Not paying advance tax

  • Forgetting e-verification

  • Missing loss carry-forward claim

Avoiding these ensures smoother processing and faster refunds.

Final Thought

After 25 years in financial markets, I can confidently say:

“Tax compliance is not about fear of notices. It is about financial discipline.”

Investors focus heavily on returns but often ignore reporting accuracy. The Income Tax system today is data-driven and automated. Transparency is no longer optional  it is expected.

File accurately. Reconcile carefully. Preserve documents.

Your wealth deserves protection not penalties.
