By Motley Fool StaffUpdated Jun 9, 2025 at 12:29 AM

Key Points

  • Reinvest dividends to buy more shares; consider tax when selling shares accumulated via DRIPs.
  • Dividends received outside IRA are taxable, increasing your stock's tax basis over time.
  • Track cost basis annually by recording taxed dividends, adjusting original share purchase prices.
