A tried-and-true tax-saving strategy for investors is to sell assets at a loss to offset gains that have been realized during the year. If you have cashed in some big gains this year, consider looking for unrealized losses in your portfolio and selling those investments before year end to offset your gains. This can reduce your 2017 tax liability.
But what if you expect an investment that would produce a loss if sold now to not only recover but thrive in the future? Or perhaps you simply want to minimize the impact on your asset allocation. You might think you can simply sell the investment at a loss and then immediately buy it back. Not so fast: You need to beware of the wash sale rule.
