If the Tax Cuts and Jobs Act is not extended, marginal tax rates are predicted to increase across most brackets, with some going from 12% to 15%, 22% to 25%, 24% to 28%, 32% to 33%, and 37% to 39.6%.
"so the question is if these tax cuts don't get extended what would happen to tax rates I'll show you this is what would happen if you make over $1,900 your tax rates are going to go up the marginal tax bracket rates would go up in almost all brackets except the lowest tax bracket and then this tax bracket right here where it would stay at 35% so this will go from 12% to 15% 22% to 25% 24% to 28% 32% to 33% 35% would stay the same right here and then this would go from 37% to 39.6%"
