Senate Republicans are pitching their recently-passed tax plan as a middle-class tax cut, but analysis from the nonpartisan Joint Committee on Taxation pokes holes in this claim. The vast majority of households earning under $100,000 will see little tax change by the time the bill is fully implemented in 2027. Twice as many households earning under $100,000 will actually see a tax hike rather than a tax cut. In total, 127 million households earning under $100,000 will see a tax increase or little change, compared with 13 million households seeing a tax cut.

Households claimed $1.6 billion in casualty losses in 2015, including over $1 billion by households making under $100,000. The Senate GOP tax plan shifts the burden onto families suffering losses from theft or natural disasters to pay for tax giveaways to large corporations and the very wealthy. The Senate plan would restrict the casualty loss deduction to disasters that receive a Presidential Disaster Declaration (PDD), which will leave out many families.

The tax legislation Senate Republicans are expected to bring to the floor this week compromises donations to nonprofits that touch virtually every part of American life, from education and health care to financial literacy and public lands. Estimates of similar plans show that annual charitable contributions could drop by as much as $11 billion under the Republican tax proposal.

The Senate tax cut proposal makes the GOP’s priorities clear—once the bill is fully implemented, it will raise taxes on individuals in order to make tax cuts for corporations permanent. In 2027, the bill raises taxes on the individual side of the code by $43 billion while cutting taxes on corporations by $54 billion. Because corporate equity is mostly owned by wealthy Americans, this has the effect of making the tax code more regressive—shifting the tax burden more towards working families.
