Capital Gains Tax is levied on the profit from selling an asset at a higher price than you paid. The basic formula is: Capital Gain = Selling Price - Cost Basis (purchase price). Type depends on holding period: Short-term: held 1 year or less - taxed as ordinary income (10%-37% in 2024). Long-term: held over 1 year - preferential rates (0%, 15%, or 20%). Example: You bought stock for $10,000 and sold for $15,000. Your capital gain is $5,000. If held 14 months (long-term): at 15% bracket, you'd owe $750 in tax. If held 10 months (short-term): taxed at your ordinary rate, potentially $1,100-$1,850. Netting Rules: Short-term gains and losses are netted first, Long-term gains and losses are netted second, Then combined, Losses offset gains, Up to $3,000 net capital loss can offset ordinary income annually, Unused losses carry forward indefinitely. Additional Taxes: Net Investment Income Tax (NIIT): 3.8% on investment income if AGI exceeds $200,000 (single) or $250,000 (married).

Examples: Single with $60,000 taxable income: 15% on gains, Married with $150,000 combined: 15% bracket, High earners over $500k: 20% bracket. Short-term gains are always taxed as ordinary income at 10%-37%. Strategy: Holding investments over 1 year can save significantly. A $50,000 gain held 13 months at 15% = $7,500 tax. Same gain held 11 months (33% bracket) = $16,500 tax. Holding longer saved $9,000.
Cost Basis is what you paid for an asset and determines your taxable gain. Original Cost Basis: Purchase price + Brokerage fees/commissions + Other acquisition costs. Adjusted Cost Basis includes: Plus: Capital improvements (for real estate), Reinvested dividends (stock purchases), Plus: Legal/professional fees related to purchase. Minus: Depreciation taken (real estate), Return of capital distributions. Example - Stock: Buy 100 shares at $50 = $5,000 + $10 commission = $5,010 basis. Sell at $75 = $7,500 - $5,010 = $2,490 gain. Example - Home: Purchase price: $300,000, Additions: $50,000 (kitchen, deck), Selling costs: $20,000 (commission, fees), Total basis: $370,000. Sell for $500,000, Gain: $130,000.

Record Keeping: Save all purchase confirmations, Track reinvested dividends, Document improvements (homes), Keep records for 7+ years after sale. Brokerages now track basis and report to IRS on Form 1099-B.
Tax-Loss Harvesting is selling losing investments to offset capital gains and reduce taxes. How it works: Sell investments at a loss, Losses offset gains dollar-for-dollar, Up to $3,000 can offset ordinary income, Unused losses carry forward indefinitely. Wash Sale Rule: Cannot claim loss if you buy same/substantially identical security within 30 days before or after sale. Maintains position but defers loss. Example: You have $20,000 in gains and $8,000 in losses. Harvest the $8,000 loss: Offset $8,000 of gains, Net gain: $12,000, Tax savings: approximately $1,800-$2,400 (at 15-20% rate). Strategic Timing: December: Harvest losses to offset year gains, January: Rebuy different but similar investments, Avoid wash sale by waiting 31 days or buying different fund. Annual Limits: Unlimited offset against capital gains, Max $3,000 against ordinary income, Carry forward unused losses. ETF Swaps: Sell S&P 500 ETF at loss, Buy Total Market ETF (not substantially identical), Maintain market exposure, Claim loss immediately.
