The tax law is facing problems in the House. The Republicans want tax reform and big cuts in rates, but they are balancing this by eliminating most deductions so as to arrive at a balanced package that will not increase the deficit. However they are struggling to find deductions to eliminate that will not kill them politically. So they are not touching home mortgage interest deduction worth $68.1 B. The Capital Gains Exclusion for Sale of Principal Residence may be eliminated but that saves only $48.5 Billion. Eliminating the Exclusion for Employer provided Health Insurance is being looked at for elimination altogether for a savings of $235.8 Billion. But this will increase the after tax premiums for the half of all Americans with health insurance who get their insurance at a discount through their employers. They want to reduce the tax deferral of defined contribution retirement plans that include 401K's but that would be hugely unpopular.
