News and resources about the impact of the new federal tax law on businesses

On December 20, 2017, Congress passed the most extensive tax reform since 1986, which was subsequently signed into law by President Trump. Included in the Tax Cuts and Jobs Act (TCJA) are changes to the Internal Revenue Code (“Code”) that impact business owners and the taxes they pay.
Here are highlights of some of the most important changes:
Individual and corporate tax rates
The TCJA lowers the marginal (top tax bracket) tax rate applicable to individuals from 39.6% to 37%. The net investment income tax (NIIT) and Medicare surtax of 3.8% and 0.9%, respectively, remain. The reduction in tax rates is not permanent like the corporate tax rate reduction, and is scheduled to expire after 2025. The tax rates applicable to long-term capital gains of individuals remains at 15% or 20%, depending on adjusted gross income (AGI).
The new tax law also lowers the corporate income tax rate permanently to 21%, starting in 2018, and eliminates the corporate alternative minimum tax (AMT).

Deductions for certain pass-through businesses
TCJA establishes a 20% deduction of qualified business income (QBI) from certain pass-through businesses. Specific service industries, such as health, law, and professional services are excluded. However, joint filers with income below $315,000 and other filers with income below $157,500 can claim the deduction fully on income from service industries. This provision would expire December 31, 2025. Read more about QBI

Business interest expense deductions
The new tax law limits the deductibility of net interest expense to 30% of earnings before interest, taxes, depreciation, and amortization (EBITDA) for four years, and 30% of earnings before interest and taxes (EBIT) thereafter. Learn more about interest expense limits.
