No, the total US corporate tax rate is 24%, so even if all deductions were eliminated, it’d still be a big cut (17% reduction -> 4 / 24) but some deductions will still make it in. But there are a LOT of US industries that do pay 35%+ federal income taxes (retail, hospitality, small business, restaurants, etc). The one I currently work for (hospitality) and my last firm (retail) both have over 35% tax rate.
