WASHINGTON — The Treasury Department and the Internal Revenue Service today released final regulations (PDF) and additional proposed regulations (PDF) under section 168(k) of the Internal Revenue Code on the new 100% additional first year depreciation deduction that allows businesses to write off most depreciable business assets in the year they are placed in service by the business.

The regulations released today on IRS.gov have been submitted to the Federal Register and may vary slightly from the published documents due to minor editorial changes. The documents published in the Federal Register will be the official documents.

The final regulations finalize the proposed regulations issued in August 2018 which implement several provisions included in the Tax Cuts and Jobs Act (TCJA). The proposed regulations contain new provisions not addressed previously.

The 100% additional first year depreciation deduction generally applies to depreciable business assets with a recovery period of 20 years or less and certain other property. Machinery, equipment, computers, appliances and furniture generally qualify.
