Long-term capital gains are one of the biggest tax breaks in the code

US long-term CGT is 0%, 15% or 20% depending on income. Short-term (ordinary income) can be 37% — the same money taxed twice as hard.

India taxes equity LTCG at 10% over ₹1 lakh, STCG at 15%. Real estate uses indexation — inflation adjusts your cost basis, cutting the taxable gain.

Tax-loss harvesting: sell losers to offset winners. In the US you can also deduct up to $3,000 of net losses against ordinary income each year.
