evidence: Trump has pitched an across-the-board tariff of 10% to 20%, plus a 60% levy on goods from China. Harris has said Trump’s proposed tariffs on foreign goods would amount to a national sales tax that would raise prices "on middle-class families by almost $4,000 a year." The projected dollar impact on consumers varies, so this rates Half True. Two estimates generally support Harris’ $4,000 figure; two show a smaller impact.

Harris’ tax plan, which is based on Biden’s, proposes a tax increase of about 7% over the next decade, which is far lower than the 300% increase that Trump claimed. The top 1% of taxpayers, a level that starts at just under $1 million a year in income, would bear about 83% of the proposed Biden tax increase. Taxpayers earning up to $60,400 would see their yearly taxes decline on average, and taxpayers earning $60,400 to $107,300 would see an annual increase of $20 on average.
