WHEN YOU SELL a bad securities investment, the one saving grace is that you can at least claim a capital loss deduction, right?
Not necessarily. In fact, all or part of your capital loss deduction will be disallowed for federal income tax purposes if the dreaded wash-sale rule applies. And thanks to some recent IRS guidance, you now have to worry about IRA transactions triggering a wash sale problem, too. Here's an update on how the wash-sale rule works:
When you have a disallowed wash-sale loss, it doesn't just vaporize (except when an IRA is used to acquire substantially identical securities, which I'll explain later). Instead, the disallowed loss gets added to the tax basis of the acquired securities — the ones that triggered the wash-sale rule in the first place.
Then, when you sell those securities, the extra basis from the disallowed wash-sale loss either reduces your tax gain or increases your tax loss. In effect, the disallowed loss is converted into a "built-in loss" that will be taken into account when you sell the substantially identical securities. By the same logic, your holding period for the substantially identical securities is increased by the period you held the securities for which the loss was disallowed.
Example: Say you bought 1,000 shares of Acme Bank on Jan. 2 for $20,000 and then the shares began to plummet. Being a tax-smart person (or so you thought), you bailed out on July 10 for a paltry $12,000. As a result, you have an indicated $8,000 short-term capital loss ($20,000 basis - $12,000 sales proceeds). You intend to use that loss to shelter an equal amount of 2008 capital gains. Having bagged your tax savings (or so you thought), you then reacquire 1,000 shares of Acme Bank on Aug. 1 for $11,000. Sadly, you are blissfully unaware of the wash-sale rule, which disallows the $8,000 tax loss you were expecting. Now, the disallowed loss is added into the equation, increasing the tax basis of the new Acme Bank shares you acquired on Aug. 1 to $19,000 ($11,000 to buy the shares + $8,000 for the disallowed loss). In addition, the holding period for those shares is increased by the six-plus months you held the original Acme Bank shares.
Say you sell stock for a loss, and your spouse buys identical stock within the forbidden 61-day period. The wash-sale rule would clearly apply if you file jointly. Fair enough. However, IRS Publication 550 says the wash-sale rule would apply even if you and your spouse file separate returns — although there doesn't appear to be anything backing up the government's opinion. Nevertheless, ignore it at your own risk.
According to IRS Publication 550, the wash-sale rule should also apply when substantially identical securities are purchased by a corporation under your control. However, the government's opinion is apparently based on an ancient 1935 court decision that may or may not have any validity in today's world. Once again, ignore it at your own risk.
