Get to know the top 10 changes made by the Tax Reform

The American Tax Reform (HR 1) was approved on December 22, 2017, and many people still do not know how this will affect their tax planning. This is the biggest change in US tax law in the last 30 years.
The new rules have been described and analyzed in a document with more than 560 pages. Thankfully, there’s no need to memorize the information of each of these pages to organize your finances: you can always count on the guidance of a certified public accountant (CPA—a professional who deals with legal, tax and accounting issues under the seal of approval of the US government) to decide your next steps.

Count on a CPA’s guidance to understand how tax reform affects you and your business

Here are some of the key changes brought about by the Reform so that you’ll get to know which ones apply to you and your business. Remember: the changes took effect in 2018 and are valid until 2025. After that, there may be changes.

Legal Entities

  • Adjustment in the Income Tax for Legal Entities: The main point of the Tax Reform is the reduction of taxes for companies: the rate fell from 35% to 21%, already in 2018. With the reduction, the US follows the trend of members of the Organization for Economic Cooperation and Development (OECD), which reduced the average of this tax from 32.5% in 2000 to 24.2% in 2016. But be aware: the new tax rate applies to corporations with a profit from operations in U.S.
  • Elimination of the Alternative Minimum Tax (AMT) for corporations: The AMT existed to ensure that all corporations would pay a minimum tax rate on their taxable income and allow credits for these payments to be transferred from one year to the next. With the reform, the AMT is gone and corporations are exposed to a 21% rate on their profit from this year.
  • Deduction of taxation on the repatriation of dividends: Dividends from foreign subsidiaries that are distributed to shareholders (corporate entity with more than 10% equity interest for a period longer than 1 year) are 100% deductible for US Income Tax purposes.
    Attention! On the other hand, the credit related to Income Tax paid abroad or the deduction of this amount by companies that fall under the exemption described above is no longer allowed.

Changes are aimed at the growth of the American economy
  • Taxation on retained earnings in foreign subsidiaries: Retained earnings not distributed by foreign subsidiaries will be taxed at 15.5% for amounts held in cash (or equivalent) and 8% for amounts held in non-liquid assets. This tax can be paid in a period of up to 8 years.
  • Increase in deduction in Section 179: With the reform, the limit for depreciation deduction of assets allocated in the operation in a given company fiscal year has increased: from USD 510,000 it has risen to USD 1,000,000.


  • Adjustments in the Income Tax thresholds for individuals: The thresholds for personal income tax have changed. The new values are valid between the years 2018 and 2025. Check it out:
