A Wash Sale occurs if you sell stock at a loss, and buy substantially identical securities with in 30 days before or after the sale.
Simply Track is a wash sales / schedule d program that calculates wash sales between what the IRS refers to as "substantially identical" stock or securities. So if you trade options, or stocks and options on the same underlying stock or security and incur losses, you may have a wash sale problem.
According to the IRS you should report all wash sales as well, meaning those transactions where you buy substantially identical securities within 30 days before or 30 days after the sale. Losses resulting from wash sale transactions may not immediately be claimed for tax purposes. The one good thing about wash sales is that you may get to claim the loss in a later tax year if you do not have substantial gains. The disallowed amount is always added to the cost of the repurchased stock, so the wash sale loss can be claimed when the security is later sold.
Simply Track generates wash sale reports with a click of the mouse to make sure you get the correct tax credit allowed from wash sale adjustments. For the sample trades discussed in previous post you get the following report obviating some really complex computations:
