President Donald Trump signed his $3.4 trillion budget bill into law Friday, enshrining an extension of tax cuts, temporary new breaks for tipped workers and funding to crack down on illegal immigration.

The 2017 bill brought about sweeping, albeit temporary, changes to the tax code. Provisions which nearly doubled the standard deduction, upped the monetary thresholds for tax brackets, lowered the top tax rate and bumped up the child tax credit were set to expire at the end of 2025.

Flanked by Republican legislators and members of his Cabinet, Trump signed the multitrillion-dollar legislation at a desk on the White House driveway, then banged down a gavel gifted to him by House Speaker Mike Johnson that was used during the bill’s final passage Thursday.
