Tax Law Update Offers Relief for Business Aircraft Buyers

The Internal Revenue Service has issued interim guidance on bonus depreciation under Section 168(k) of the US tax code, clarifying how the tax benefit may apply in certain purchase scenarios. The Trump administration’s One Big Beautiful Bill Act of 2025 permanently reinstated 100% bonus depreciation for qualifying property, including new and used aircraft acquired and placed in service after January 19, 2025. According to AeroTime, National Business Aviation Association (NBAA) said the IRS recently issued Notice 2026-11 providing interim guidance on bonus depreciation under Section 168(k) of the US tax code. NBAA emphasized that the analysis remains highly fact-specific and that aircraft owners should review their situation with an aviation-experienced tax advisor.
