Tax on Capital gains, in form of TDS, is not deducted at source be it short term or long term. You need to include all your incomes when calculating your advance tax liability such as Capital gains, dividend, business income from trading, etc during the financial year.
If your tax liability is above INR 10,000, you are liable to pay advance tax during the financial year in 4 different instalments.
- 15th June - 15% of the tax liability
- 15th Sept - 45% of the tax liability
- 15th Dec - 75% of the tax liability
- 15th March - 100% of the tax liability
If you are eligible to pay advanced tax but have not paid advance tax, a penalty will be applicable u/s 234B and 234C. You can claim the tax credit for the advance tax paid when filing your ITR. Capital gains on listed equity shares of a domestic company are taxed at:
LTCG is taxed at 10% above INR 1 Lakh
- STCG is taxed at 15%
Hope this helps!
