Happy New Year!


I want to wish my friends and clients a very Merry Christmas and Happy New Year. Here are a few year end tips to consider. Please be sure to consult your tax adviser first, since every taxpayer is in a different situation.

1. In 2018, the standard deduction will be $12,000 for single filers and $24,000 for joint filers. If you don't think you will have enough deductions to itemize in 2018, you should maximize your itemized deductions this year. For example, you can make your January 2018 mortgage payment now to get a higher mortgage interest deduction in 2017. Also, if you were planning on donating to a charity in 2018, consider making the donation in 2017 to be sure you get the write-off.

2. If you are a business and have the option of deferring some of your income into 2018, you may want to do so, since I believe most businesses will be taxed at a lower rate in 2018.

3. In 2018, the combined deduction for State and Local Taxes (SALT) and real estate taxes will be capped at $10,000. If you have any state estimated taxes due on 1/15/18, I would advise paying them in 2017 to take advantage of the deduction this year. Also, if you will hit the $10,000 cap in SALT and real estate taxes in 2018 and have real estate taxes due in January 2018, I would consider paying them before year-end. Keep in mind this strategy won't help you if you get hit with AMT.
