<P> The law also impacts healthcare by repealing the ACA individual mandate, resulting in projections of up to 13 million fewer persons covered by health insurance as some younger, healthier persons will likely choose not to participate . Those in the remaining less healthy pool will pay higher insurance costs on the ACA exchanges, which will result in additional persons dropping coverage . </P> <P> Critics in the media, think tanks and academia assailed the law, mainly based on forecasts of its adverse impact (e.g., higher budget deficit, higher trade deficit, greater income inequality, lower healthcare coverage and higher healthcare costs), disproportionate impact on certain states and professions and the misrepresentations made by its advocates . Some of the reforms passed by the Republicans have become controversial within key states, particularly the $10,000 cap on state and local tax deductibility, and are being challenged in federal court . </P> <P> The House passed the penultimate version of the bill on December 19, 2017, though for Senate procedural reasons small changes were needed and a revote was held in the House . The Senate passed the final version on December 20 in a 51--48 vote and that final version was passed by the House of Representatives on that same day . The bill was signed into law by President Donald Trump on December 22, 2017 . Most of the changes introduced by the bill went into effect on January 1, 2018 and will not affect 2017 taxes . </P> <Table> Single filers (2018) <Tr> <Th_colspan="2"> Under previous law </Th> <Th_colspan="2"> Under current law </Th> </Tr> <Tr> <Th> Rate </Th> <Th> Income bracket </Th> <Th> Rate </Th> <Th> Income bracket </Th> </Tr> <Tr> <Td> 10% </Td> <Td> $0--$9,525 </Td> <Td> 10% </Td> <Td> $0--$9,525 </Td> </Tr> <Tr> <Td> 15% </Td> <Td> $9,525--$38,700 </Td> <Td> 12% </Td> <Td> $9,525--$38,700 </Td> </Tr> <Tr> <Td> 25% </Td> <Td> $38,700--$93,700 </Td> <Td> 22% </Td> <Td> $38,700--$82,500 </Td> </Tr> <Tr> <Td> 28% </Td> <Td> $93,700--$195,450 </Td> <Td> 24% </Td> <Td> $82,500--$157,500 </Td> </Tr> <Tr> <Td> 33% </Td> <Td> $195,450--$424,950 </Td> <Td> 32% </Td> <Td> $157,500--$200,000 </Td> </Tr> <Tr> <Td> 35% </Td> <Td> $424,950--$426,700 </Td> <Td> 35% </Td> <Td> $200,000--$500,000 </Td> </Tr> <Tr> <Td> 39.6% </Td> <Td> $426,700 and up </Td> <Td> 37% </Td> <Td> $500,000 and up </Td> </Tr> </Table>
