Wash sales must be calculated across brokerage accounts. If you maintained multiple accounts these must be combined at year end in order to prepare for reporting your taxes
TradeLog provides an End Tax Year procedure that performs the following accounting functions:
Automatically creates new separate data files for each brokerage account for the next tax year with the same name as the current tax year data file. For example, "2010 Combined.tdf" would generate files for the following year named "2011 Schwab.tdf" "2011 Fidelity.tdf" and "2011 eTrade.tdf".
Moves forward all year end open positions from the current tax year data file into the new tax year data files.
Moves forward all January trades from the current year data file into the new tax year data files.
Generates wash sales and moves forward any wash sales that are deferred into the new tax years data file.
Tradelog will prompt you to verify that this is what you want to do.
Enter the tax year you are working on. Then click OK
Enter a descriptive name for the combined file. Then click OK
Highlight all the files that need to be combined and then press Open
Note: To highlight multiple items in Windows, press and hold the Control key (Ctrl) on your keyboard and simply click on each individual file.
TradeLog will prompt you to save your records. Click Yes
You will then be informed that this is a combined file and that no edits may be made to it. Click OK
Your files have now been combined into one data file. This file is located in the MyDocuments/tradelog folder of your hard drive with the descriptive name that you gave.
Please move onto the next set of instructions
Running the End Tax Year Function:
Running the End Tax Year function from the combined data file will create individual next tax year data files complete with your open positions carried over to next year, any wash sale deferrals, and your January trades. Do not run the End Tax Year from the individual broker data files.
Click File, Open and open the combined file that was just created.
With the data file now open, click ALL
Click File, End Tax Year / Create Next Tax Year Data File
TradeLog will prompt you to confirm that you have imported your January trades. Again, please make sure that you have imported a full 13 months worth of data prior to running this function (January 1 through January 31 of the next tax year).
Click Yes if you have already done so or No if this needs to be done.
TradeLog will tell you that the Next Tax Year data file has been prepared and the new name of this file. This new file will be located in the same folder as your current file - which is by default the MyDocuments/tradelog folder of your hard drive.
