SURCHARGE ON TOTAL INCOME REG

Long term Capital Gains on the sale of real estate are taxed at 20% after the indexation benefit. 

Long-term capital gains over Rs 1 lakh on listed equity shares are taxable at 10% without the benefit of indexation. Here the shares are sold through a recognised stock exchange where STT has been charged.  

Are you asking about capital gains?

Or about surcharge?

They are both completely different things and not related to each other.

The only link between the two is that all your income (including capital gains) is added up to determine if you are subject to surcharge.

If yes, then the surcharge is applied on the income tax amount (and not on any income figures)m
