Toward the end of 2006, I read an article on year-end tax advice. They advised taking losses in order to offset realized capital gains. This advice is definitely not aimed at investors like me who buy an S&P 500 index fund and that's it. But then I got to thinking...
Suppose I buy $30K worth of an index fund at the beginning of the year. At the end of the year, it's down 10% ($3K). So I sell it off with the intention of immediately buying it back next year. Then, when I go to file my taxes, I have a $3K loss. Assuming I'm in the 25% tax bracket, that saves me $750 in taxes. I take the $750 in tax savings and plunge it back in to the index fund. What's the net effect?
Obviously, I have $750 more invested than I would have had I just sat on the fund. That's a plus. On the down side, my basis has been decreased. My original basis was $30K. After the the re-buy, including the tax savings, my basis is down to $27,750. That's a difference of $2,250. So when I sell the fund in the future, I will owe additional taxes (assuming I'm making a profit). In the case of short-term gains (again, 25%), I will owe $562.50 in additional taxes. In the case of long-term gains (15% rate), I will owe $337.50 in additional taxes.
In either case, I'm ahead. It almost seems like a tax-deferred investment. The government gives me an extra $750 to invest (in the form of tax savings) but I will owe more taxes, later. In retrospect (now that I've written it down), it doesn't seem like it should be legal. Has anyone done this sort of thing?
