Here is the best summary of most of the salient proposals that are currently written into the bill:
Details of tax reform legislation revealed
It is likely that most of these changes that would affect most of you have been discussed above.
Worthy of noting, however are the following:
Elimination of the Section 43 and 45I credits (Enhanced Oil Recovery Credit and Producing Oil and Gas from Marginal Wells [strippers] Credit.)
Elimination of the deduction (50% allowable) for entertainment, amusement, or recreation expenses. The deduction for meals (50% or 80% if in the transportation industry) appears to be retained.
Capping the deduction for interest at 30% of adjusted taxable income for businesses with > $25,000,000 in gross receipts.
The 25% maximum rate for pass-through entities (S-Corps, partnerships, sole proprietors and farmers/fishers) excludes personal services businesses like law, medicine, accounting, engineering, performing arts, athletics, and consulting. How this affects the computer services industries is unclear, but I would suppose that if personal services are a majority component of gross receipts, that those highly-paid self-employed computer types would likely not benefit from this 25% rate.
Repeal the like-kind exchange rules for personalty.
Interest income from Private Activity Bonds and Bonds used to build sports stadiums or arenas would no longer be exempt from federal tax.
No more loopholes for deducting executive compensation > $1,000,000 on corporate tax returns. The deduction is capped at $1 million with no ability to deduct performance incentives, and it expands the definition of those subordinate executives who would have their compensation deduction capped.
Good news for Ohmman: The excise tax on private foundations' net investment income drops to 1.4% from 2%.
We shall see how this particular sausage making exercise winds up. Like most things tax related, the devil is in the details, and we have not seen the details. Time will tell how long it takes for the IRS to issue new regulations interpreting any new law (if it is signed into law.)
