What’s in the Final Tax Bill
January 1, 2018

House and Senate Republicans have released a final plan to resolve the differences between their tax overhaul bills. The legislation would cut taxes for corporations. American taxpayers, in large part, would also get cuts, though most of the changes affecting taxpayers would expire after 2025.
Income taxes | Current Law | G.O.P. Bill |
The bill would lower individual tax rates overall. But to comply with Senate budget rules, the individual tax cuts would expire after 2025. | ||
Tax brackets | Seven | Seven, lower overall |
Top rate | 39.6% | 37% |
starts at: | $426,700 / $480,050 (singles/couples) |
$500,000 / $600,000 (singles/couples) |
Alternative Minimum Tax | Alternative income tax calculation for high-income taxpayers | Keeps, but increases exemption so fewer will pay it |
Standard deduction and exemptions | ||
The standard deduction would nearly double, so many more people would end up taking it. | ||
Standard deduction | $6,500 / $13,000 (singles/couples) |
$12,000 / $24,000 (singles/couples) |
Personal exemptions | $4,150 per taxpayer and dependent | Eliminates |
Family tax credits | ||
The child tax credit would double, and it has a larger refundable portion that would allow more lower-income families to benefit. | ||
Child tax credit | $1,000 | $2,000 |
Refundable portion: | 15% of earnings over $3,000 | Up to $1,400 |
Credit for other dependents | None | $500 |
Family tax credits phase out starting at: | $75,000 / $110,000 (singles/couples) |
$200,000 / $400,000 (singles/couples) |
Inflation | ||
The biggest long-term change for taxpayers in the bill, it would result in a tax increase over the long run, long after the tax cuts expire. | ||
Inflation measure used for certain income thresholds | Consumer Price Index (CPI) | Chained CPI (C-CPI), a less generous measure |
Education |
Current Law |
G.O.P. Bill |
Education credits | American Opportunity Tax Credit, Lifetime Learning Credit and Hope Scholarship Credit | No change |
Student loan interest deduction | Can deduct up to $2,500 | No change |
Graduate student tuition waivers | Tuition waivers are not treated as taxable income | No change |
A big victory for families that send their children to private school. | ||
Education savings plans | None | Expands use of 529 college savings accounts to include K-12 private school tuition |
Deduction for classroom expenses | $250 deduction | No change |
Itemized deductions | ||
Some Republican representatives in high-tax districts have said they will vote “no” because of the scaling back of the “SALT” deduction. | ||
State and local tax deduction | Income or sales and property taxes are deductible | All state and local tax deductions limited to $10,000 |
Mortgage interest deduction | Can deduct interest payments on up to $1 million of debt | Limited to payments on $750,000 of debt |
Moving expenses | Can deduct personal expenses | Eliminates, except for members of the military |
Employer-provided expense reimbursements are excluded | Eliminates, except for members of the military | |
This deduction, which would have been eliminated by the House bill, is most important to low-income taxpayers with high out-of-pocket health care costs. | ||
Medical expenses deduction | Can deduct out-of-pocket expenses in excess of 10% of adjusted gross income | Expands by reducing threshold to 7.5% of income Applies to 2017 and 2018 |
Overall limit on itemized deductions | Phase out beginning at $266,700 / $320,000 (singles/couples) |
Repeals |
Other individual taxes | ||
This provision, estimated to save over $300 billion, would severely weaken the Affordable Care Act.
|
||
Individual mandate | Penalty for not having health insurance | Eliminates Starts in 2019 |
Estate tax | Top rate of 40% on estates above $5.6 million | Increases threshold to estates above $11.2 million |
Pass-through income | Taxed at individual rates | 20% deduction, phasing out starting at $315,000 of income for couples |
Capital gains | Top rate of 23.8% (including net investment income tax) | No change |
Corporate taxes | Current Law | G.O.P. Bill |
The largest tax cut in the bill would be permanent, as would other corporate tax changes. | ||

The Senate’s decision to keep the corporate A.M.T. was reversed after blowback from several industries.

New investment purchases | Complex rules for deducting over many years | Five years of full expensing, then phased out over five more years |

The bill raised money by speeding up the effective dates for these last two provisions, which were included in the Senate bill. | ||
Net operating losses | Can deduct net operating losses from income in other years | Limits the deduction to 80% of taxable income |
Research and development expenditures | Can be immediately deducted | Would need to be written off gradually |

International | ||
The bill would move from the current worldwide tax system, in which income earned abroad is taxed in the United States, to a territorial system in which only domestic profits would be taxed. | ||
Taxation of multinational companies | Worldwide system with deferral and credit for taxes paid abroad | Modified territorial system with new anti-abuse tax |
One-time repatriation tax | — | 8% (15.5% for cash) |
