The Tax Cuts and Jobs Bill (H.R. 1) is the first significant tax reform effort undertaken by Congress in more than 30 years. The bill was passed by both the House and the Senate and signed into law by President Trump.

Standard Deduction. The standard deduction increases from $6,350 (2017) to $12,000 for individuals, from $9,300 (2017) to $18,000 for heads of household and from $12,700 (2017) to $24,000 for married couples.

Personal Exemption. The deduction for personal exemptions is repealed through 2025.

Child Tax Credit. The Child Tax Credit increases to $2,000 from the current $1,000. An additional $500 credit is provided for each non-child dependent. Also, Social Security numbers for children are required before claiming the enhanced credit.

Alternative Minimum Tax. The AMT remains but the exemption amount increases to $70,300 for individuals and $109,400 for married filing jointly, affecting fewer taxpayers.

Capital Gains and Dividends. The maximum tax rate remains at 23.8% (20% plus the 3.8% Medicare tax for taxpayers with income above $200,000 for individuals or $250,000 for married filing jointly). The 20% capital gains income threshold increases to $425,800 for individuals ($479,000 for married taxpayers filing jointly).

Estate Tax. The exemption (currently $5.5 million) immediately doubles to $11.2 million in 2018 and remains at this level for the next six years, after which time the estate tax is eliminated completely (tax year 2026 and beyond).

Education-Related Tax Credits and Deductions. 529 Savings Plans are expanded to allow some funds (up to $10,000 for certain expenses) to be used for K-12 education. Rollovers to Achieving a Better Life Experience (ABLE) Sec. 529A accounts will be allowed as well. The student loan interest deduction remains.

Mortgage Interest Deduction. Remains but with a few changes such as allowing the interest deduction for up to $750,000 (currently $1 million) in mortgage principal on new homes. Existing mortgages are grandfathered in. Homes entered into contract before December 15, 2017, and closed on by April 1, 2018, are able to use the prior limit of $1 million.

Home-equity loans. The home-equity loan interest deduction is repealed through 2025.

State and Local Income Tax Deduction and Real Estate Tax Deduction. Preserved. Deduction allowed for up to $10,000 a year in state and local income or property taxes.

Note: Taxpayers who prepay 2018 state income taxes, a common tax strategy, can only take the prepaid 2018 amount as a deduction on their 2017 tax returns for the amount already assessed. For example, taxpayers can prepay their fourth quarter income taxes (typically due January 15, 2018) before December 31, 2017.

Charitable Contributions. Deductions for charitable donations remain; however, for charitable contributions of cash to public charities the percentage of income limit increases to 60%.

Medical Expense Deductions. The Medical expense deduction (currently 10% of AGI) is temporarily lowered to 7.5% of income for tax years 2017 and 2018.

Miscellaneous Deductions. Many are repealed through 2025 including those relating to tax preparation, alimony payments (after December 31, 2018), and moving expenses with the exception of the moving expense reimbursement for members of the Armed Forces on active duty who move because of a military order.

Adoption Tax Credit. Remains.

Electric Vehicles. The $7,500 tax credit (Sec. 30D) for the purchase of electric vehicles remains.

Individual Healthcare Mandate. Penalty is eliminated for tax years starting after 2018.



Corporate Tax Rate. Starting January 1, 2018, the corporate tax rate is reduced to a flat rate of 21% (down from 35%). The corporate AMT is repealed.

Territorial Taxation. Companies with offshore earnings, currently taxed at a 35% rate, would transition to a territorial tax system. Under the tax reform bill income derived from offshore earnings, if repatriated, would be subject to an effective tax rate of 15.5% for earnings held in liquid assets (i.e. cash) and 8% for illiquid (other) assets.

Business Interest. Small businesses (under $25 million) retain the ability to write-off interest on loans subject to limitations.

Business Expensing. Businesses would be allowed to immediately write-off the full cost of new equipment at 100% through tax year 2022, after which it would be phased down over a four-year period.

Business Entertainment Expenses Deduction. The deduction for business entertainment expenses is eliminated.

Pass-through Entities. The tax rate on pass-through business entities is reduced to a maximum of 20% for tax years starting January 1, 2018, and ending on December 31, 2025.

Low-income Housing Tax Credit. Remains.

Research & Development Tax Credit. Remains.
