🇮🇳 How Taxes Work on Stocks in India

In India, capital gains tax depends on the holding period and asset type:

Asset Type	Short-Term	Long-Term	Holding Period
Equity Shares / Equity Mutual Funds	15% (STCG)	10% (LTCG above ₹1 lakh)	12 months
Debt Mutual Funds	As per slab rate	20% with indexation	36 months
Unlisted Shares	As per slab rate	20% with indexation	24 months
ETFs / REITs / InvITs	15%	10%	12 months

The calculator automatically classifies this and applies the correct rate.

💡 Example:
If you bought shares at ₹100 and sold at ₹150 after 10 years, your ₹50 gain per share (₹5 lakh total) falls under LTCG @10%, taxable on profit above ₹1 lakh.

🇺🇸 U.S. Capital Gains Tax Rules

In the United States, your tax depends on your income bracket and holding period:

Type	Holding Period	Typical Tax Rate
Short-Term Capital Gain	Held < 1 year	Taxed as ordinary income (10–37%)
Long-Term Capital Gain	Held > 1 year	0%, 15%, or 20% depending on income

💡 Example:
If you held Apple stock for 3 years and made a $10,000 gain, the calculator applies 15% LTCG, resulting in $8,500 post-tax profit.

🇬🇧 U.K. Capital Gains Tax Rules

For the United Kingdom, you get an annual CGT exemption (£3,000 for FY 2025-26).

Taxpayer Type	Tax Rate on Gains (Post-Allowance)
Basic Rate	10% (non-property), 18% (property)
Higher / Additional Rate	20% (non-property), 28% (property)

The calculator handles this automatically — factoring your holding period and asset class.
