The Internal Revenue Service has announced the annual inflation adjustments for a number of taxrelated provisions for 2018, including, of course, the latest tax rate schedules and tax tables. These are the numbers for the tax year 2018 beginning January 1, 2018 (assuming there are no big changes as the result of tax reform). They are not the numbers and tables that you’ll use to prepare your 2017 tax returns in 2018 (if you need those figures, please see page 8 of this report). You’ll use these numbers to prepare your 2018 tax returns in 2019. If you aren’t expecting any significant changes in 2018, you can use the updated tax tables and other tax numbers to estimate your liability. If you expect to make more money or have a change in your circumstances (i.e., get married, buy a house, start a business, have a baby), consider adjusting your withholding or tweaking your estimated tax payments.
