What individual taxpayers can do right now to lower their taxes

At the end of every year, millions of Americans can make strategic moves to shave a few bucks off their April tax bill. Right now, millions more should be able to get into the act, with Congressional Republicans poised to pass a 503-page law that fundamentally restructures the U.S. tax code.

If the bill passes, new tax rates and countless other provisions would go into effect on Jan. 1. Most of the old rules, though, would still apply in the last two weeks of 2017 — and that gives individuals a shrinking window of time to employ strategies that would lower their taxes for next year's tax season. (While the legislation would take effect in the new year, it won't be reflected in your tax forms until the 2019 tax season).

So, here are suggestions from accountants, financial planners and other tax experts on how to make the most of this opportunity. Keep in mind that the best advice depends specifically on how you're going to be affected by the tax bill. While most Americans would get a tax cut in the short term, some taxpayers could see higher tax bills in 2018.

"No individual is average," Suzanne Shier, a tax strategist at Northern Trust Corp., reminds us. "An average is a composite of multiple individuals."

If your taxes are set to spike in 2018, many of these strategies won't work as well. But if you're part of the majority who will see an initial tax benefit from the law, there could be big benefits for acting soon.

1. Give to charity

A typical piece of end-of-the-year advice is to increase your potential deductions before Jan. 1. Deductions claimed for things you did this year will lower tax bills due the following April. Wait until January, and you'll need to cool your heels for more than a year to get the benefit of deductions claimed.

And even if your tax rate is going up next year under the new bill, you may still want to make a bunch of charitable donations in 2017. Most deductions, including the charitable one, can only be claimed if you itemize your tax return. The bill would sharply limit the number of taxpayers who would benefit from itemizing: First it raises the standard deduction from $6,350 to $12,000 for single people, and $12,700 to $24,000 for married couples. Second, it limits other deductions — most famously for state and local taxes — so it's harder for taxpayers to reach the threshold where itemizing makes sense.

So, you might want to think about making several years of charitable donations this month if you can afford it, said Philip "Rusty" Ross, a financial adviser at Exencial Wealth Advisors based in Oklahoma City. If you're not sure where to donate, you can open a donor-advised fund and decide later where your money will go. But move fast — there are only two weeks left in December.

2. Defer income

Another traditional recommendation for this time of year is to defer income. While salaried workers generally can't choose when they get paid, business owners can often delay registering income until the following year, lowering their April tax bill in the process. Investors can also control their taxable income — and thus lower capital gains tax bills — by selling losing stocks or waiting to sell winning stocks until 2018. In most years, deferring income merely delays the taxes you will have to pay eventually. But, if you expect your tax rate to fall next year, deferring income into 2018 could actually save you money. (There's also some good news for equity investors when it comes to the FIFO rule.)

4. Employee expenses

Current tax law allows employees to deduct unreimbursed expenses related to their jobs as long as they're more than 2 percent of income. The tax bill ends these itemized deductions after the end of this year. So, workers should think about whether they can pay — and get the receipts — for as many of these expenses as possible this month, said Kathy Pickering, executive director of the Tax Institute at H&R Block in Kansas City, Mo. Examples of unreimbursed expenses for employees might include tools and supplies, occupational taxes, work uniforms, union dues, and expenses for work-related travel. Self-employed people and business owners would still be able to deduct expenses under the new tax bill.
