One big tax break, for this year, that is overlooked, is connected to the ObamaCare mandate. If you recall, Judge Roberts and the Supreme Court threw Obama and the Democrats a bone, when it suggested that Obama Care was tax, and not a mandate that forced people to buy a product. The extra health care cost, under Obama, was a huge tax increase on the middle class that averages about $450/mo for a single person and about $1200/mo for a family. That is $6000/year for a single and $14,000 for a middle class family. For the average middle class family this is more than all their other taxes combined.
When Trump got rid of the mandate, he eliminated this tax, since it can no longer be called a tax, if it cannot be forcefully collected by the IRS via the mandate. Without the mandate, it is now an imposed free market choice, which is unconstitutional. This is huge hidden tax break, based on the legal games played by Obama and a counter punch performed by Trump.
People no longer need insurance, because it is no longer a forced tax. It is now a consumer choice. It is optional, but many people are afraid not to have it. There are many people, who are shelled shocked due to excessive use of force by the Democrats. It will be up to each person to decide how much tax break, they will give themselves. This can be done by dropping insurance, or by shopping around for cheaper plans that tailor to needs. Trump is also making it easier to shop around, so the hidden tax break can be as large as possible.
