Hi George,
For equity funds, the time period for the calculation of LTCG tax rate is 1 year, if the holding period is less than one year, then it is treated as Short Term Capital Gain (STCG). LTCG is made taxable over 1 lakh on listed equity shares is made taxable at the rate of 10% without the benefit of indexation. STCG is taxed at a rate of 15%. For debt funds, the period of calculation of LTCG and STCG is 3 years, which means if the holdings are sold before completion of three years, then it is treated as STCG and if after 3 years, then it is LTCG. LTCG is taxed at a flat rate of 20% with indexation benefit. For STCG, the gains/returns are added to the income and are taxed according to the slab rate of the income tax.
Hope this helps!
