Well, I’m just pleased to get a bigger standard deduction - and I get it from the State, too. I wasn’t even aware of this until today :-)
The old Personal Exemption was used whether you took the Standard Deduction or Itemized Deductions.
Ah, I saw this thread and the page 40 reference threw me slightly too.
I doubt any small business owner is not aware of it by now, but, the (up to) 20% deduction for small business owners (Section 199A deduction) is quite nice too. It is in particular “nice” if one’s spouse works some other job, as that helps get the full deduction, in many cases.
