Considerations
Some differences in proceeds are to be expected between your 1099-B and your GainsKeeper Realized Report. The Check-Up 1099-B comparison tool is designed to help you easily reconcile your taxable gain/loss, as reported by GainsKeeper, to your 1099-B. This tool will look at the data in your account and pull out the same information that your broker uses for your 1099-B, then put that side-by-side with what your actual tax figures are, so that you can see exactly where the differences are coming from. Differences highlighted in this tool include:
Options - Brokers do not report proceeds on options, but the IRS requires them to be reported, and they are included on your GainsKeeper report. The 1099-B comparison tool gives you a sum total for all options proceeds reported in your current year proceeds.
Short Sells - Brokers report proceeds on shorts in the year that the short is executed, regardless of when the short is covered. In accordance with the IRS, GainsKeeper reports proceeds on short sells in the year that the short is covered. The 1099-B comparison tool will identify any differences in proceeds caused either by short sells executed in the current tax year that were not closed by 12/31, or short sales open in prior tax years that were covered in the current tax year.
Proceeds from certain corporate actions - Your broker will not adjust your proceeds for certain types of corporate actions, but GainsKeeper will. Your 1099-B comparison tool will identify any instances where you have proceeds from corporate actions not reported by your broker.
If these expected differences cannot account for your discrepancies, then you may have a data issue. Compare your year-end Unrealized and Realized summary information as reported in View Accounts with your broker records. If trades are missing, they can be added manually using Record Trades>Stock (or Option, Bond, etc.). Trades can be deleted or edited from the Trade Log.
