It's been a bad year
Tax planning in a bad year has two approaches: First, because of the special deal on capital gains, you may want to create capital gains and keep other income low. Or second, maybe you want to drag income into 2018, since you are in a lower tax bracket.
Capital Gains in 2018
Dragging Income into 2018
If you've recently sold stocks at a loss, consider using the wash sale rules to kill the losses and so increase your 2018 income.
Other Ideas for a Bad Year
If you've been collecting unemployment benefits, be sure to have your taxes calculated early to avoid last-minute surprises, since the benefits are subject to federal tax.
