The major proposals pitched by the campaigns of Vice President Kamala Harris and former President Donald Trump would both expand the federal budget deficit—though Trump's plans would require significantly more borrowing over the next decade.
Trump's proposals would add an estimated $5.8 trillion to the deficit over the next decade, according to the Penn Wharton Budget Model, a fiscal policy think tank at the University of Pennsylvania (Trump's alma mater). Most of Trump's deficit-increasing policies result from proposed changes that would reduce Americans' tax burden. He's called for permanently extending the 2017 tax cuts, which would add an estimated $4 trillion to the deficit over the next decade (unless Trump comes up with offsetting spending cuts). His plan to eliminate taxes on Social Security benefits will add another $1.2 trillion.
