Filing capital gains tax correctly is one of the most common challenges for new investors in India. Many make mistakes that either lead to overpayment, penalties, or missed tax-saving opportunities. This guide will help you identify common mistakes, provide step-by-step solutions, and offer actionable tips to ensure smooth and accurate filing.
Problem 1: Ignoring Short-Term vs Long-Term Capital Gains
Many investors fail to distinguish between short-term (STCG) and long-term capital gains (LTCG) when selling stocks or mutual funds.
Solution:
- STCG (<1 15="" at="" equities="" for="" is="" ltcg="" taxed="" year="">1 year) above Rs.1 lakh is taxed at 10% without indexation.1>
- Keep a record of purchase and sale dates for accurate calculation.
- Use examples: Investing Rs.1,00,000 in a stock for 8 months and selling at Rs.1,20,000 → STCG = Rs.20,000 → tax = Rs.3,000.
Problem 2: Not Accounting for Brokerage and Transaction Charges
Investors often calculate gains based on buy and sell prices without considering brokerage or STT (Securities Transaction Tax).
Solution:
- Deduct brokerage and STT from your gain to calculate taxable income accurately.
- Example: Buy at Rs.50,000, sell at Rs.60,000, brokerage Rs.500 → taxable gain = Rs.9,500.
- Maintain a separate record or spreadsheet for all charges to avoid errors.
Problem 3: Forgetting to Include Dividends as Taxable Income
Some investors assume dividends are tax-free, but dividends from stocks and mutual funds can be taxable under the dividend distribution tax rules.
Solution:
Problem 4: Incorrectly Reporting Gains from Multiple Accounts
Many new investors hold accounts across multiple brokers and fail to consolidate capital gains, leading to underreporting.
Solution:
- Download consolidated annual statements from all brokers.
- Sum up STCG and LTCG separately across accounts.
- Use example: Account A gains Rs.15,000 (STCG), Account B gains Rs.25,000 (STCG) → total STCG = Rs.40,000.
Problem 5: Ignoring Indexation Benefits for Debt Mutual Funds
Some investors miss the opportunity to reduce LTCG tax on debt mutual funds using indexation.
Solution:
- Apply cost inflation index (CII) to the purchase price for debt mutual funds held over 3 years.
- Example: Invest Rs.1,00,000 in debt fund 4 years ago, CII adjusted cost Rs.1,20,000, sell at Rs.1,50,000 → LTCG taxable = Rs.30,000.
- Helps reduce tax liability significantly.
Problem 6: Filing ITR Late or Incorrectly
Late filing or incorrect ITR forms can lead to penalties and interest on unpaid tax.
Solution:
- Always file ITR before the deadline using correct forms (ITR 2 for capital gains).
- Double-check all entries against Form 26AS and broker statements.
- Example: Late filing leads to 1% per month interest on unpaid tax; timely filing avoids this.
By following these solutions, new investors can avoid common capital gains tax mistakes, save money, and file their returns accurately. Maintaining records, using calculators, and double-checking entries are key to stress-free tax filing.
