iAfter last minute political and procedural hurdles were cleared, the Tax Cuts & Jobs Act (the "Tax Act") was passed on December 20 and signed into law by President Trump on Dec. 22, 2017. The new law makes the most dramatic changes to the tax code since 1986. Importantly, in addition to this comprehensive federal tax overhaul, there are significant state tax implications.
The table below provides highlights of specified provisions included in the Tax Act, and compares the new tax provisions with the law in place prior to the passage of 2017 tax reform. There are many nuanced changes, which should be reviewed carefully based on each taxpayer's specific facts and circumstances. In addition, there are no IRS regulations or guidance at this point, and there have been no comprehensive state tax analyses done to compute what the state corporate and individual income tax implications will be.
*With certain exceptions, the individual tax provisions generally expire for tax years after December 31, 2025. One permanent change affecting tax liabilities of individuals is a change in the manner in which indexing for inflation is done. The new indexing uses what is called "chained CPI-U" rather than the standard "CPI-U" measure that had been used previously. Economic measures indicate the likely result of this change will be that indexed increases in tax brackets and phase-out thresholds will be slowed, which will result in increased tax liabilities for individuals as time passes. The corporate tax provisions included in the new law generally are permanent.
