Option MMs lived pretty much in a tax free world until the change.
The wash sale rules do
not apply to a dealer in stock or securities.
Under the current rules, market makers do not "live in a tax free world." However, they are not subject to the wash sale rules. Their positions are
marked to market at the end of the year. This effectively means that they use
unrealized gains and losses, as of the last day of the year, for tax purposes. Of course, they also report realized gains and losses. But they are
not subject to the wash sale rules.
The idea that the wash sale rule was somehow implemented because market makers were not paying taxes does not make sense, because the wash sale rules are not applicable to market markers.
what is the problem with actually allowing the tax loss in that situation?
The IRS view is that it's not a real loss because you bought the stock again too soon. As I have previously noted, the time frame of 30 days is arbitrary. Some legislative committee, or some team of tax lawyers who work for the IRS, decided 30 days was good way to define an "artificial loss" that does not really count for tax purposes. What if you sell the stock at a loss and buy it back
four minutes later? What about
eighteen seconds later?
Would you be willing to concede that at some point, the taxpayer is engaged in a transaction that
has no economic substance, that his or her intent is
not to sell the stock, and that the sole purpose of the transaction is to claim a loss for tax purposes?
Based on some earlier comments you made in this theread, it sounds like you are arguing that taxpayers should be allowed to use an
unrealized loss to reduce their taxable income. But if that was allowed, would you require that same taxpayer to report
unrealized gains as income as of the last day of the year?
You can't have it both ways. You can't use unrealized losses to reduce your income while not including unrealized gains. The treatment has to be consistent.
