U.S. Vice President Kamala Harris has announced a basket of economic proposals aiming to lower living costs for middle and lower-class Americans and boost the economy overall by using tax incentives and other tax shifts.

Goldman Sachs recently estimated Harris' 28% proposed corporate tax rate would reduce S&P 500 earnings by about 5% starting in 2026, but Wall Street isn't particularly concerned about the Harris tax plan.

Vice President Kamala Harris is expected to build on her economic platform Wednesday when she delivers an economy-focused speech in Pennsylvania, after the nominee has already called for an “opportunity economy” focused on the middle class and released plans that include lowering grocery and prescription drug prices and addressing the housing crisis.
