2018 TCJA vs. 2017 Tax Code: Case Study Comparisons, by Jean Mammen, EA

How do Maria De Lima (Case Study I) and Carlos W. Masaryk (Case Study II) Fare?

The case studies are found both on my website http://www.1040nror1040.com  and in my book, “1040NR? or 1040?   U.S. Income Tax Returns for Visa Holders   +   International Organization and Foreign Embassy Employees”  https://www.amazon.com/1040NR-1040-Income-Returns-Holders/dp/1986498603/ref=sr_1_1?s=books&ie=UTF8&qid=1535673889&sr=1-1&keywords=Jean+Mammen

The bottom line of each case study has Maria and Carlos coming out slightly better in 2018 than in 2017. The loss of the personal exemption and the small amount of itemized deductions that Carlos could no longer take were slightly outweighed by the lowering of the applicable tax bracket from 15% to 12%.
