What is Capital Gains Tax?
Capital gains tax is the tax you pay when you sell an asset for more than you bought it. Common taxable assets include:
- Stocks & bonds
- Real estate (except your primary home, in some cases)
- Mutual funds & ETFs
- Cryptocurrencies
- Business assets
Example:
- You bought 100 shares of a company at $50 each ($5,000 total).
- You sell them later at $80 each ($8,000 total).
- Your profit = $3,000.
- This $3,000 is considered a capital gain and may be taxed.
Types of Capital Gains
The IRS splits capital gains into two categories:
1. Short-Term Capital Gains
- Assets held 1 year or less
- Taxed as ordinary income (same as your salary)
- Rates range 10% to 37% (based on your income bracket)
2. Long-Term Capital Gains
- Assets held more than 1 year
- Taxed at lower rates: 0%, 15%, or 20% (depending on income)
- Encourages long-term investing

How to Calculate Capital Gains Tax (Step-by-Step)
- Determine your cost basis (purchase price + fees)
- Find selling price (minus selling costs like commissions)
- Subtract basis from selling price = Gain or Loss
- Classify as short-term or long-term
- Apply correct tax rate
Example:
- Bought rental property for $200,000
- Spent $20,000 on improvements
- Sold for $300,000 with $10,000 closing costs
- Gain = $300,000 – ($200,000 + $20,000 + $10,000) = $70,000
- If held for 3 years → long-term gain taxed at 15% or 20%
Strategies to Reduce Capital Gains Tax
- Hold assets longer → qualify for long-term rates
- Use tax-advantaged accounts (IRA, 401k)
- Harvest losses → offset gains with losses
