The final funding package was passed as an omnibus spending bill, the Consolidated Appropriations Act, 2018, enacted on March 23, 2018.

The Trump administration proposed its 2018 budget on February 27, 2017, ahead of his address to Congress, outlining $54 billion in cuts to federal agencies and an increase in defense spending.

[25] On October 19, 2017, Senator Heidi Heitkamp (D-N.D.) proposed an amendment to prevent tax increases on people making less than $250,000 a year.

[27] The bill contained a continuing resolution and a suspension of the debt ceiling lasting until December 8, as well as additional disaster funding for FY2017.

On Friday, February 9, funding lapsed again at midnight after Senator Rand Paul delayed the vote on the Bipartisan Budget Act of 2018, which included another continuing resolution, by objecting to measures requiring unanimous consent to expedite the parliamentary process.

In addition, its passage was uncertain in the House due to opposition by both fiscal conservatives who objected to the increased deficit spending, and by liberals who opposed the omission of a DACA provision.

[32][33] However, it passed the Senate 71–28 and the House 240–186 after midnight, and President Trump signed the bill early that morning, prior to when furloughs were to begin.

[38] On December 20, 2017, Congress passed the Tax Cuts and Jobs Act of 2017, two days after which President Trump signed it into law.

After accounting for macroeconomic feedback effects, the Joint Committee on Taxation estimates that it will add a net of approximately $1 trillion to the federal debt over the period 2018–2027.
