Read the full account

On 22 December 2017 President Trump signed the Tax Cuts and Jobs Act (Public Law 115-97). The statute cut the federal corporate rate from 35 to 21 percent, created a territorial-leaning international regime, expanded the standard deduction, limited SALT deductions, and added a time-limited individual-rate cut.

Context

A Republican Congress wrote and passed the bill on party-line votes using reconciliation. CBO and JCT scored revenue losses. Pass-through provisions and the SALT cap have distributional effects. Trump signed; he did not write the code section by section.

Donald Trump did not act alone on every file. Congress, courts, agencies, foreign counterparts, and later administrators share specific instruments. Office-holding is not automatic authorship of every downstream welfare series. Allegation is not a completed judgment.

Why it matters

A large corporate-rate cut and pass-through preferences increase expected after-tax income concentration at the top.

What the sources establish

Congress.gov text of Public Law 115-97 and JCT/CBO scores are official. Independent reporting records the signing. They do not convert the statute into a unique Gini point the same week without a later series.

Established: TCJA signed 22 December 2017 with the corporate 21 percent rate and listed structural changes. Not established: a unique long-run wage coefficient from the signing ceremony.

The score must not treat every later stock buyback as this statute, or treat state tax systems as rewritten.

Congress wrote it on a party-line reconciliation vote. Treasury implements.. Co-authors and later implementers named in Context remain on the file. A later repeal, court stay, or successor order would be a different Fact with a different date. The contribution type is direct. Trump’s documented role is limited to the instrument named in the title. He did not write the independent newspaper; the newspaper did not enact the instrument. Driver income-inequality is used because the mechanism in the FDI description is the one the evidence can actually support. Off-family indicator padding is refused. That pair identifies Trump signs the Tax Cuts and Jobs Act, not a later speech about Trump signs the Tax Cuts and Jobs Act.
