Account Value, Profits, and Losses

Now that you understand confirmations (per-transaction) and statements (periodic summaries), let's look at what those statements actually report: account value, gains, losses, and cost basis.


Realized vs. Unrealized Gains and Losses

This is a fundamental distinction that affects both account reporting and tax treatment:

TypeDefinitionWhen It OccursTax Impact
RealizedGain or loss from an actual sale or disposition of a securityWhen the position is closedTaxable event in the year of sale
UnrealizedPaper gain or loss on a position still heldWhile the position remains openNot a taxable event until the position is closed
  • Account statements reflect the current market value of positions, showing unrealized gains and losses
  • Realized gains and losses are reported on confirmations and year-end tax documents (Form 1099-B)

Example: You buy 100 shares at $50. The stock rises to $70.

  • Unrealized gain: $2,000 (shown on your statement, not taxable yet)
  • If you sell at $70: Realized gain of $2,000 (reported on Form 1099-B, taxable)

Cost Basis Reporting

  • Broker-dealers must report cost basis to both the customer and the IRS for covered securities
  • Covered securities include:
    • Stocks acquired on or after January 1, 2011
    • Most other securities (bonds, options, mutual funds) acquired after January 1, 2012 or later, depending on type
  • Cost basis determines the gain or loss when a security is sold

Think of it this way: Cost basis is your starting line. When you sell, the IRS measures how far you moved from that line to determine your taxable gain or loss.

Exam Tip: Gotchas

  • Unrealized gains are NOT taxable. Only realized gains trigger a tax event. The exam may describe a customer whose portfolio has appreciated significantly and ask about tax consequences. If the customer hasn't sold, the answer is no taxable event has occurred.
