My method obviously won't tell you WHERE the impact hits you, but since my filing conditions are basically the same, total tax divided by total (or taxable) income gives the direction.
I went far beyond "inactive" and quit everything regarding CPA stuff... Was thinking about "inactive" but I wasn't a very good CPA and thought if I ever had to go back to that line of work I'd look for anything else. I was never an "angle" guy and always had trouble with the billable hour. Lots of my old clients were new and unsophisticated and needed lots of hand-holding. Partner I worked for didn't like write-offs.
I do still brag about being a first-time passer back in 1992 thanks to the Becker course I took in Indy!
The bold is one of the reason's I like working for myself.
On the topic of this thread though, I've decided to provide my tax clients a sheet which shows them the following:
1. Deductions/exemptions lost from tax reform
2. Deductions/credits gained from tax reform
3. Net of items 1 & 2
4. Effective rate in 2017 and 2018.
5. Comparison of #3 above to the difference in #4
