TAX CONSIDERATIONS FOR STOCK INVESTORS
Plain English
The IRS taxes stock gains differently based on how long you held the stock. Hold for over a year and you pay lower long-term capital gains rates (0%, 15%, or 20%). Hold for under a year and profits are taxed as ordinary income — up to 37%. This one distinction can cost you thousands.
Going deeper
Capital gains taxes: Short-term gains (held < 1 year) are taxed as ordinary income (up to 37%). Long-term gains (held > 1 year) are taxed at 0%, 15%, or 20% depending on income. The Wash Sale Rule prevents you from claiming a tax loss if you repurchase the same (or substantially identical) security within 30 days before or after selling at a loss. Tax-loss harvesting is deliberately selling losing positions to offset gains — you can deduct up to $3,000 of net losses against ordinary income per year, with excess carrying forward. Tax-advantaged accounts (401k, IRA, Roth IRA) defer or eliminate taxes on gains. Dividends: Qualified dividends are taxed at long-term capital gains rates. Ordinary dividends are taxed as income.
Examples
The $10K Tax Difference
You made $50,000 trading stocks. If you held all positions < 1 year (short-term): taxed at 32% income rate = $16,000 in taxes. If you held all positions > 1 year (long-term): taxed at 15% = $7,500. Same gain, but $8,500 more in your pocket by simply waiting.
Wash Sale Trap
You sell SPY at a $5,000 loss on Dec 28 for a tax deduction. Three days later (Jan 2), you buy SPY again. The IRS wash sale rule disallows your $5,000 loss — you can't claim it because you bought back within 30 days. The loss gets added to your cost basis instead.
