I had brought this up back when the tax changes occurred.  I recommended people look into their bracket and structure as the changes, which happened immediately, will typically impact middle-class income negatively.

 Some people will have to file quarterly among other changes.  An Obama Administration change gave people a three year preparation period, again... three years to prepare, and people still blamed Obama for a tax alteration that they, or their tax person, ignored for three years.

 This current change gave people less than a year, and had more direct effect.  I imagine this one will be Hillary's fault.

 Along these lines there is legal limitations to the IRS advertising that you can have your taxes prepared for free.  H&R Block and TurboTax are the primary corporations seeing this through for obvious reasons, but just in case information can be found here:

Don't ever underestimate the evil one.
