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.

The US president signed the multi-trillion dollar legislation outside the White House in time for the nation’s birthday.
