After much searching and no success in finding the actual tax law that was passed last year, I turned to my Congressional Representative.  He pointed me to http://www.thomas.gov/

Per the about page, this database:
“THOMAS was launched in January of 1995, at the inception of the 104th Congress. The leadership of the 104th Congress directed the Library of Congress to make federal legislative information freely available to the public. Since that time THOMAS has expanded the scope of its offerings to include the features and content listed below.”

It has: Bills, Resolutions; Activity in Congress; Congressional Record; Schedules, Calendars; Committee Information; Presidential Nominations; Treaties; Government Resources; For Teachers; Help and Contact

You can search by bill number or text.

Without further fan fare here is the revised tax law:  http://www.gpo.gov/fdsys/pkg/BILLS-111hr4853enr/pdf/BILLS-111hr4853enr.pdf

Happy reading – be prepared to refer back to prior bills/laws.
