If it becomes law, after signed by the President, then the IRS will have to go into the IRC to make changes and then update their systems and then put the information out to software developers, who will in turn have to make changes to their software which may require IRS approval.
We will have to wait and see what happens to determine what, if any, new course of action should be taken by taxpayers.
