The Senate’s budget plan allows for extending the individual and estate tax cuts under a scoring method that treats them as not adding to future deficits, even though the Congressional Budget Office has projected the extension would cost more than $3.8 trillion over 10 years, not including higher interest payments.

As in an earlier Senate plan, the new framework also calls for $150 billion in new defense spending and $175 billion for border security. That previous plan would have left tax changes for later, but Trump and House leaders preferred to roll up their agenda in what the president dubbed “one big, beautiful bill.”
