The bill, ushered through Congress by Republican leadership and signed by Trump Friday, includes $4.5 trillion in tax cuts, slashes spending on Medicaid, and creates temporary tax deductions for overtime and tipped income. It includes $170 billion for immigrant detention and for new personnel for Immigration and Customs Enforcement.

Some of the bill’s changes go into effect later this year, while others won’t start until after the midterms in 2026.
