Final GOP Tax Plan Announcement

19 December 2017

Late on December 15, 2017, the GOP members of the House and Senate announced its final tax plan. The chart below summarizes our current, individual income tax laws along with a comparison of the new tax plan.



In addition to the individual tax plans summarized in the chart, the final GOP tax plan calls for the following changes to corporate tax laws:

  • Lower corporate tax rate to 21% (from 35% today);
  • Tax U.S. company foreign income at 15.5% rate (cash) or 8% rate (non-cash);
  • Repeals corporate AMT; and
  • New 20% Qualified Business Income Deduction for passthrough entities effectively subjects only 80% of pass-through entity income at normal, ordinary income tax rates. This deduction would apply to the first $315,000 of joint income (limited to 50% of W-2).

The U.S. currently taxes any corporation domiciled in the U.S. on its income, regardless of where it has been earned worldwide. A territorial tax system, by comparison, taxes a foreign corporation only on income earned in that country alone (without assessing additional tax on income derived outside of the foreign country). The GOP anticipates adopting the territorial corporate tax system as modified above.

Despite their control of both houses of Congress, the Republican Party lacks the “supermajority” necessary to avoid filibusters. Without a supermajority, the Republican Party may still need to compromise over the final version of any income tax legislation. If any such changes arise, this piece will be updated accordingly.

As previously noted, these new laws would be subject to a sunset after the year 2025. Separate pieces will address and discuss tax planning opportunities for this tax year and next.
