Course Summary

Taxes are triggered by events, not by growth. You only owe capital gains tax when you sell an investment for a profit, not while it sits in your account appreciating. This is why long-term investors can let their wealth compound for decades without annual tax drag - they control when to realize gains by choosing when to sell.

Holding period determines your tax rate. Investments held more than one year qualify for long-term capital gains rates (0%, 15%, or 20%), which are significantly lower than short-term rates that mirror ordinary income tax (up to 37%). A few extra days of patience before selling can save you thousands in taxes.

Losses are valuable for tax purposes. Tax-loss harvesting lets you sell investments at a loss to offset gains and reduce your tax bill. Losses offset gains dollar-for-dollar, and up to $3,000 of excess losses can offset ordinary income each year. Just watch the 30-day wash sale rule when repurchasing.

Tax-advantaged accounts are your greatest ally. 401(k)s, IRAs, and Roth accounts let your investments grow without annual taxes on dividends and capital gains. Traditional accounts give you a tax break now; Roth accounts give you tax-free withdrawals in retirement. Using these accounts effectively can add tens of thousands to your wealth over time.
