The Tax Cuts and Jobs Act (TCJA) has enhanced two depreciation-related breaks that are popular year-end tax planning tools for businesses. To take advantage of these breaks, you must purchase qualifying assets and place them in service by the end of the tax year. That means there’s still time to reduce your 2018 tax liability with these breaks, but you need to act soon.

“Going green” at home — whether it’s your principal residence or a second home — can reduce your tax bill in addition to your energy bill, all while helping the environment, too. The catch is that, to reap all three benefits, you need to buy and install certain types of renewable energy equipment in the home.

Because donations to charity of cash or property generally are tax deductible (if you itemize), it only seems logical that the donation of something even more valuable to you — your time — would also be deductible. Unfortunately, that’s not the case.

Donations of time or services aren’t deductible. It doesn’t matter if it’s simple administrative work, such as checking in attendees at a fundraising event, or if it’s work requiring significant experience and expertise that would be much more costly to the charity if it had to pay for it, such as skilled carpentry or legal counsel.

However, you potentially can deduct out-of-pocket costs associated with your volunteer work.

When teachers are setting up their classrooms for the new school year, it’s common for them to pay for a portion of their classroom supplies out of pocket. A special tax break allows these educators to deduct some of their expenses. This educator expense deduction is especially important now due to some changes under the Tax Cuts and Jobs Act (TCJA).

If you received a large refund after filing your 2017 income tax return, you’re probably enjoying the influx of cash. But a large refund isn’t all positive. It also means you were essentially giving the government an interest-free loan.

That’s why a large refund for the previous tax year would usually indicate that you should consider reducing the amounts you’re having withheld (and/or what estimated tax payments you’re making) for the current year. But 2018 is a little different.

To avoid interest and penalties, you must make sufficient federal income tax payments long before your April filing deadline through withholding, estimated tax payments, or a combination of the two. The third 2018 estimated tax payment deadline for individuals is September 17.

If you don’t have an employer withholding tax from your pay, you likely need to make estimated tax payments. But even if you do have withholding, you might need to pay estimated tax. It can be necessary if you have more than a nominal amount of income from sources such as self-employment, interest, dividends, alimony, rent, prizes, awards or the sales of assets.

If you purchased qualifying property by December 31, 2017, you may be able to take advantage of Section 179 expensing on your 2017 tax return. You’ll also want to keep this tax break in mind in your property purchase planning, because the Tax Cuts and Jobs Act (TCJA), signed into law this past December, significantly enhances it beginning in 2018.

To help you make sure you don’t miss any important 2018 deadlines, we’ve provided this summary of when various tax-related forms, payments and other actions are due. Be aware that some deadlines have been moved up or pushed back compared to previous years. Please review the calendar and let us know if you have any questions about the deadlines or would like assistance in meeting them.

Various limits apply to most tax deductions, and one type of limit is a “floor,” which means expenses are deductible only if they exceed that floor (typically a specific percentage of your income). One example is the medical expense deduction.

Because it can be difficult to exceed the floor, a common strategy is to “bunch” deductible medical expenses into a particular year where possible. If tax reform legislation is signed into law, it might be especially beneficial to bunch deductible medical expenses into 2017.

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. So if you’ve 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.
