The One Big Beautiful Bill Act changed everything for business owners planning major purchases in 2026. Bonus depreciation is back at 100%: and it's permanent.
For years, business owners watched this tax benefit shrink. It dropped from 100% in 2022 to 80% in 2023, then 60% in 2024, and hit just 40% in 2025. The plan was complete elimination by 2027. That phase-out is over. Starting January 19, 2025, qualifying business assets get the full write-off again.
This isn't a temporary fix. It's indefinite tax policy that gives you certainty for small business tax planning decisions years into the future.
What Changed Under OBBBA
The legislation reversed the scheduled decline. Property acquired and placed in service after January 19, 2025, qualifies for 100% bonus depreciation. The IRS confirmed these changes through Notice 2026-11 in January, providing interim guidance businesses can rely on immediately.
Previously, buying a $100,000 piece of equipment in 2025 meant deducting only $40,000 in year one. The remaining $60,000 spread across future years using standard depreciation schedules. Now? The full $100,000 comes off your taxable income in 2026.
Qualifying Property
Not every purchase qualifies. The asset must meet specific criteria:
Recovery period of 20 years or less. This includes most tangible business property except real estate structures.
Newly purchased. You can't claim bonus depreciation on property you already owned. Used equipment counts if you're buying it for the first time: someone else's used is your new.
Placed in service after January 19, 2025. The date you start using the asset for business purposes matters, not just the purchase date.
Eligible asset categories:
- Equipment and machinery
- Commercial vehicles
- Computer systems and software
- Office furniture and fixtures
- Interior improvements to commercial buildings (qualified improvement property)
- Certain aircraft
- Film and television production costs
- Sound recordings
- Farming plants
The full list runs longer, but these cover most small business scenarios. If you're investing in tools, technology, or transportation for your operation, you're likely covered.
Growth Strategy Implications
Permanent 100% bonus depreciation transforms capital planning. Previously, the shrinking deduction created urgency: buy now before the benefit disappears. That pressure is gone.
What replaces it? Strategic opportunity.
Cash flow acceleration. Full first-year deductions mean immediate tax savings. A $200,000 equipment purchase at a 25% effective tax rate returns $50,000 in tax savings the same year. That's capital you can reinvest immediately rather than waiting years to recoup through gradual depreciation.
Competitive positioning. Businesses that modernize equipment, upgrade technology, or expand capacity gain operational advantages. The tax code now subsidizes these improvements at the maximum level indefinitely.
Scalability planning. Growth often requires significant capital investment. Knowing you can write off qualifying assets fully in year one makes expansion math simpler. Revenue projections align with tax benefits in the same period.
For business formation services clients, this matters from day one. New businesses making initial equipment purchases get substantial first-year deductions that offset startup income. That early tax relief improves survival odds during critical first years.
Timing Considerations
January 19, 2025, marks the dividing line. Property placed in service before that date follows old phase-out rules. After that date, full bonus depreciation applies.
"Placed in service" means ready and available for business use. Ordering equipment in December 2025 but receiving it in February 2026? The February date controls. The asset enters service in 2026, so it qualifies.
Complex acquisitions need careful structuring. Large machinery orders with long delivery times should account for installation dates. Construction assets under long-term development follow special timing rules worth reviewing with a tax professional.
Section 163(j) interactions. This interest expense limitation ties to your business's adjusted taxable income. Accelerating deductions through bonus depreciation can reduce ATI, potentially limiting interest deductibility. Businesses with significant debt should model these interactions before making large purchases.
Most small businesses won't hit 163(j) thresholds, but it's worth checking if you're carrying substantial loans.
Flexibility Through Elections
The law provides options. You're not forced to take 100% bonus depreciation if it doesn't fit your tax strategy.
Election out entirely. Some businesses prefer spreading deductions across multiple years for income smoothing purposes. You can choose standard depreciation schedules instead.
Partial elections for transition property. Property placed in service during your first tax year ending after January 19, 2025, can use 40% bonus depreciation instead of 100%. Long-production-period property and certain aircraft qualify for 60% under transition rules.
Why choose less? Tax planning isn't always about maximum current-year deductions. Businesses expecting higher tax rates in future years might benefit from deferring deductions. Startups projecting losses this year but profitability next year might skip bonus depreciation to save deductions for when they're more valuable.
Elections must be made on timely filed tax returns. Work with your tax advisor during return preparation to make strategic choices.
Real-World Application
Consider three scenarios:
Manufacturing expansion. A small manufacturer buys $500,000 in new production equipment. Under old rules at 40%, they'd deduct $200,000 now and carry $300,000 forward. At 100%, the entire $500,000 comes off 2026 income. At a 25% tax rate, that's $125,000 in immediate tax savings versus $50,000. The extra $75,000 funds working capital or additional growth investments.
Professional services upgrade. A consulting firm spends $150,000 on computers, software, and office furniture. Everything qualifies. The full deduction offsets consulting revenue in the same year. Tax savings fund marketing initiatives or staff bonuses.
Transportation fleet. A delivery business adds three commercial vehicles totaling $180,000. Vehicles qualify for bonus depreciation. The business writes off the entire cost immediately rather than depreciating over five years. Cash flow improves. The owner considers adding a fourth vehicle with tax savings.
These aren't theoretical benefits. They're immediate cash impacts that change what your business can accomplish in 2026.
Planning Your Next Move
Permanent 100% bonus depreciation removes the clock pressure but doesn't eliminate planning needs. Strategic capital investments still require analysis:
Operational necessity. Buy assets that improve efficiency, capacity, or competitiveness. Tax benefits enhance smart business decisions: they don't justify unnecessary purchases.
Budget alignment. Full deductions help cash flow but don't change purchase prices. Ensure investments fit your financial capacity.
Growth trajectory. Expansion timing should match market demand and operational readiness. Tax incentives support growth strategies; they shouldn't drive them.
Documentation matters. Maintain clear records of acquisition dates, placed-in-service dates, and business-use percentages. The IRS will expect substantiation if questioned.
For assets with mixed business and personal use, only the business portion qualifies. A vehicle used 80% for business and 20% personal gets 80% of the deduction.
Work With Professionals
Tax law complexity increases with business size and transaction scale. The reinstated 100% bonus depreciation interacts with numerous other code sections. State tax treatment varies: some states conform to federal bonus depreciation rules, others don't.
