Where possible, push into next year anything that triggers a tax liability and speed up into this year anything that generates a tax deduction. There are plenty of income items and expenses you may be able to control, and business owners and self-employed taxpayers often have the best opportunities. Consider deferring bonuses, consulting income or self-employment income. On the deduction side, you may be able to accelerate state and local income taxes, interest payments and real estate taxes. Consider paying the January mortgage bill now to benefit from the interest deduction a year early.
