/>iThere has been a great deal of information released regarding tax reform, tax cuts, and tax negotiations among the House, the Senate, and the President in 2017. And while a "deal" has been reported, there has been no published or approved bill sent to the President. However, reports indicate that certain provisions are emerging as likely components of 2017 tax reform. The chart below outlines some of the likely reform topics and compares current law, the Senate bill (note that the Senate bill provisions generally expire after 2025), the House bill, and the likely final negotiated provision.
Determining how these potential tax law changes affect a particular taxpayer presents challenges. This is a difficult task due to the overall complexity of the tax law, and the different variables that impact the net liability calculation. Once there is an enactment (assuming a law passes), it will be possible to more accurately estimate the economic effect of the new law.
*In evaluating this chart, note that the column regarding the "likely final provisions" is based on preliminary, informal reports, and these references are subject to the uncertainties of the political process. The enacted law, if there is an enacted law, could vary from what appears likely today. In addition, if a law is enacted the terms likely will be required by the Byrd Rule to sunset (i.e., expire) for tax years after a specific date, such as 2025.
