Tax Treatment of Investment Sales

Capital Gains Rules: Holding period determines tax rate.

  • Short-term (≤1 year): Taxed as ordinary income (10%-37%)
  • Long-term (>1 year): Eligible for lower rates (0%, 15%, or 20%)
  • Wash Sales: Losses disallowed if repurchased within 30 days
  • Barter Income: Taxable as ordinary income at fair market value
  • Crypto Transactions: Each trade is a taxable event
Step-by-Step Reporting Process
  1. Match all 1099-B forms to your transaction records
  2. Determine cost basis:
    • Use broker-reported basis if available
    • Calculate manually for uncovered securities
    • Include commissions and fees
  3. Complete Form 8949:
    • Separate short-term and long-term transactions
    • Note wash sales and other adjustments
  4. Transfer totals to Schedule D
  5. Report on Form 1040 (Line 7 for capital gains)
Special Considerations
  • Cryptocurrency: Each trade creates a taxable event
  • Inherited Securities: Step-up in basis to date-of-death value
  • Gifted Securities: Carry over donor's basis and holding period
  • DRIP Sales: Must track each reinvestment's basis
  • Corporate Actions: Mergers, splits require basis adjustments
Essential Recordkeeping

Maintain these records for 3+ years after filing:

  • All 1099-B forms and brokerage statements
  • Purchase confirmations and cost basis documentation
  • Records of wash sales and corporate actions
  • Barter exchange records and valuations
