26 Ways the GOP’s Tax Reform Will Affect Your Wallet

15. Investors Control Over Tax on Capital Gains

For a while, it looked like Congress might restrict the flexibility investors have to control the tax bill on their profits. Investors who have purchased stock and mutual fund shares at different times and different prices are allowed to choose which shares to sell in order to produce the most favorable tax consequences. You can, for example, direct your broker to sell shares with a high tax basis (basically, what you paid for them) to limit the amount of profit you must report to the IRS or, if the shares have fallen in value, to maximize losses to offset other taxable gains. (Your gain or loss is the difference between your basis and the proceeds of the sale.)

The Senate called for eliminating the option to specifically identify which shares to sell and instead impose a first-in-first-out (FIFO) rule. The oldest shares would be assumed to be the first sold. Because it is assumed that the older shares likely have a lower tax basis, this change would trigger the realization of more profit sooner rather than later.

In the end, though, this idea fell by the wayside. Investors can continue to specifically identify which shares to sell to arrange for the most favorable tax outcome.
