Rate and Calculation Questions
Capital gains tax applies only to profit (sale price minus your cost basis). Long-term gains (held over 12 months) are taxed at 0%, 15%, or 20% based on income. Short-term gains (12 months or less) are taxed at ordinary income rates (10-37%). Your withholding or estimated payment is due before filing — by January 15 for Q4 gains.

Reporting and Filing Questions
Capital gains from investment sales are reported via your broker’s Form 1099-B, transferred to Form 8949 and Schedule D of your tax return. Tax software imports your 1099-B automatically. Verify that the cost basis shown is accurate — especially for older accounts, corporate spin-offs, and reinvested dividends.
If you realize a large capital gain and your total withholding will not cover 90% of this year’s tax or 100% of last year’s tax, make an estimated quarterly payment by the next deadline. Q1-Q4 deadlines: April 15, June 15, September 15, January 15. Underpayment penalty applies if the shortfall exceeds $1,000.
