The Joint Committee on Taxation has released the General Explanation Of Public Law 115-97, better known as the Blue Book on TCJA (JCS-1-18).

The 457 page document contains the staff’s explanation of the provisions in last year’s Tax Cuts and Jobs Act.  Blue Books for prior laws have often been referenced and consulted by the IRS in developing guidance, as well as being referred to by advisers when dealing with matters not yet covered by IRS guidance.
