Bonus depreciation is officially back at 100%, and the rules for 2026 look very different from what many taxpayers had been planning for. After years of preparing for the gradual phase-down under the Tax Cuts and Jobs Act (TCJA), the One Big Beautiful Bill Act (OBBBA) of 2025—along with new IRS guidance in Notice 2026-11—restores full expensing for most qualified property and establishes a clearer long-term framework.
BerryDunn's tax experts have compiled a comprehensive summary of what changed, how the rules work now, and what businesses need to know as they plan for upcoming capital investments.
Notice 2026-11: Key updates driving the 2026 bonus depreciation rules
Notice 2026-11 serves as the IRS's bridge between the old TCJA regulations and the new OBBBA system. Rather than issuing a complete rewrite of §1.168(k)-2, the IRS introduced a "date substitution" approach to quickly align existing regulations with the new law.
New effective dates for determining 100% bonus depreciation
To determine whether property qualifies for the renewed 100% bonus rate, taxpayers must now:
• Use January 19, 2025, in place of September 27, 2017
• Use January 20, 2025, in place of September 28, 2017
What this means in practice: If a business acquires and places property in service after January 19, 2025, the property generally qualifies for 100% bonus depreciation under the updated rules.
Bonus depreciation requirements for 2026: Understanding the four tests
Even with the OBBBA changes, property must still satisfy four primary requirements under §1.168(k)-2 to be considered "qualified property."
1. Qualified Property Type (MACRS, QIP, Software, and More)
Eligible property includes:
- MACRS property with a recovery period of 20 years or less
- Computer software
- Qualified Improvement Property (QIP)
- Qualified sound recording productions (added by the OBBBA, new for 2025/2026)
This expansion makes the property type test more favorable for entertainment, technology, and capital-intensive industries.
2. Acquisition test: Binding contract rules matter
To qualify for the 100% deduction, the property must be acquired after January 19, 2025, based on the written binding contract date. If a binding contract existed before January 20, 2025, the property generally falls under the old 40% bonus depreciation rate, not the new 100% rate.
This distinction is critical for taxpayers evaluating bonus depreciation contract date rules for 2026.
3. Original use or used property requirements
The TCJA rules for original use and used property remain in effect:
Original-use property: The first use must begin with the taxpayer.
Used property: Still qualifies if the taxpayer (or a predecessor) did not previously use it, and it was not acquired from a related party.
4. Placed-in-service test: Why the January 19, 2025, date matters
To qualify for the 100% rate, property must be acquired and placed in service after January 19, 2025.
This rule is especially relevant for taxpayers with fiscal year ends in mid-2025 or early 2026, where assets cross the legislative changeover date.
The 40% bonus depreciation election: A strategic tax planning option
While 100% bonus depreciation is now the default, the OBBBA and Notice 2026-11 preserve the important 40% bonus depreciation election (and 60% for long-production-period property).
Why elect less than 100%?
1. Managing Net Operating Losses (NOLs)
Electing 40% can help businesses avoid creating NOLs limited by the 80% taxable income cap, preserving deductions for potentially higher-tax-rate years.
2. Preventing wasted credits
Some nonrefundable tax credits are lost if taxable income drops to zero. Using the 40% rate gives businesses more precision in aligning deductions and credits.
The election applies to the first taxable year ending after January 19, 2025, and covers all qualified property placed in service during that year.
What 100% bonus depreciation means for 2026 capital planning
With Notice 2026-11 in place, businesses now have clarity as they model 2026 capital spending. Companies with heavy investment in equipment, real estate improvements, or cost segregation studies stand to benefit the most.
The return of full expensing—combined with the new flexibility provided by the 40% election—creates a more stable and planning-friendly environment than taxpayers have seen since the early TCJA years.
