1st August 2017

The IRS recently released the 2018 inflation adjustments for several tax provisions in Rev. Proc. 2017-58, 2017-45 I.R.B. __. There appear to be no surprises here, as the revenue procedure confirmed the projections made by Bloomberg BNA in its annual special report. The adjustments apply to tax years beginning in 2018 and transactions or events occurring during the 2018 calendar year.

For the estate planner, here are some 2018 amounts to keep in mind:
