How Will Proposed Tax Reform Affect Me?
Posted by Rick Miller on December 13, 2017
The US House and Senate are considering extensive income tax reform. The table below outlines current law and the bills for each chamber as they were at the close of business on Monday, December 4, and provides indications of the bill that has emerged as the “final deal” on Wednesday, December 13. While this “final deal” has been announced, it has not been ratified. Details are sparse, and nothing will be certain until the President has signed a bill.
The two chambers’ tax reform bills differ from each other, but both propose significant changes from current law, and they are very similar in many respects. The shading in the table highlights some of the strongest similarities (one might suspect that these are likely to survive in the final bill).
What are the clearest implications of the proposed tax reform?
- As the standard deduction will be larger, fewer people will itemize. For example, fewer people will benefit from the mortgage interest deduction and from charitable deductions. If you itemize now, but probably won’t under the higher standard deduction, it may make sense to accelerate charitable giving, payment of sales and property taxes, and paying medical bills early. Consult your tax adviser before making any moves like this!
- The Alternative Minimum Tax is likely to apply only to those with higher incomes – those families with incomes between $200k and $1M who live in high tax states are likely to benefit.
- The deductibility of state and local taxes will be reduced, both directly and because fewer people will itemize. In the short term, total taxes will tend to rise for people living in high tax states (we’re looking at you, Massachusetts, New York, California…). In the longer term, there may be internal political pressure on higher tax states to lower their tax rates. [Yes, I realize that this directly contradicts the previous bullet point. No one will know the net effect for certain until they file.]
- The maximum mortgage interest deduction will be smaller – this may reduce home sale prices somewhat, even if interest rates don’t rise.
- Owners of some “pass through” businesses such as LLCs are likely to benefit due to lower tax rates, and others are likely to attempt to restructure their businesses to benefit.

Important tax reform caveats:
- The tax reform bills have now been reconciled (a “final deal” has been struck), but details are limited as of this writing, and the “final deal” has not been ratified by both houses.
- The provisions (and changes to the provisions) interact. You probably won’t know whether your taxes will go up or down until you file.
- Taxpayers and tax advisers will require time to figure out the most advantageous approaches to minimize taxes – the impact on each person will take time to emerge.
