evidence: Fact checking Harris' claim that Trump's tariff plan will cost families almost $4,000 per year: Partially true, needs context [...] Details: Harris is citing an estimate of potential costs if former President Donald Trump were to implement tariffs on imported goods. Trump has advocated for a tariff of at least 10% on most imports and a tariff of at least 60% on Chinese imports. Estimates of the potential costs and the likely scale of the tariffs vary. An analysis by the Center for American Progress Action, a progressive policy think tank, estimated that a 20% tariff on most imports, combined with a 60% tax on Chinese goods, would amount to a tax increase of around $3,900 annually for middle-income families.
