Details of the Senate Version of the Tax Cuts and Jobs Act

November 10, 2017

Late Thursday evening, the Senate Finance Committee released its version of the Tax Cuts and Jobs Act. The Senate Tax Cuts and Jobs Act shares many things with the House counterpart: both plans reduce the corporate income tax rate, move to a territorial tax system, provide full expensing of certain capital expenditures (on a temporary basis), repeal the alternative minimum tax, provide more favorable tax treatment of pass-through businesses, and eliminate many targeted tax preferences in favor of lower rates and a higher standard deduction.

The Senate approach, however, is unique in many particulars. The tables below outline the major details of the legislation.

Fully repeals the state and local tax deduction, except for taxes paid or accrued in carrying on a trade or business. Eliminates other itemized deductions as well.

Other Deductions and Exclusions

Eliminates the moving deduction and modifies the exclusion of capital gains from the sale of a principal residence, among other changes.

Child Tax Credit

The first $1,000 would be refundable, increasing with inflation up to the $1,650 base.

Permits the use of the cash method of accounting for businesses with gross receipts of up to $15 million.

Capital Investment

Allows full expensing of short-lived capital investment (currently subject to “bonus” depreciation), such as equipment and machinery, for five years. Increases Section 179 expensing from $500,000 to $1 million and increases the phaseout threshold from $2 million to $2.5 million. Reduces asset lives for residential and nonresidential real property to 25 years.

Tax Treatment of Interest

Other Taxes
