The most important tax move available to small business owners right now is sitting in plain sight, and most of the coverage I’ve seen buries the lead. The One Big Beautiful Bill Act, signed July 4, 2025, permanently restored 100% bonus depreciation. Not temporarily. Not with a sunset clause. Permanently. That single word changes the entire calculation for equipment purchases, because the old phase-down schedule, which would have dropped the rate to 20% in 2026 and zeroed it out entirely in 2027, is gone. But “permanent” doesn’t mean “whenever you get around to it.” December 31, 2026 is still the line. Buy and place qualifying property in service before that date, and you can write off the full cost on your 2026 return. Miss it, and you wait another year.
The SBA has reported that the OBBBA’s combined tax provisions have already reduced taxes for over 12 million small business owners by roughly $7,000 each on average. That’s a real number, and it tells you the law has teeth. The question is whether you’re positioned to use it before Q4 turns into a scramble.
- 100% bonus depreciation is permanent starting with property placed in service after January 19, 2025.
- Equipment must be bought AND placed in service by December 31, 2026 to count for your 2026 return.
- Qualifying property includes equipment, machinery, vehicles, and leasehold improvements (20-year recovery or less).
- Land, building structures, and inventory never qualify, no matter what a vendor tells you.
- State tax conformity is not automatic: verify your state's treatment before assuming a full state deduction.
What Actually Qualifies (and What Doesn’t)
This is where a lot of business owners get burned. The IRS, through Notice 2026-11 issued in January 2026, reaffirmed the bonus depreciation framework under Reg. §1.168(k)-2 with updated effective dates. The qualifying property list is specific: equipment, machinery, vehicles, and leasehold improvements with a recovery period of 20 years or less. A new CNC machine qualifies. A delivery van qualifies. Tenant finish-out on your warehouse qualifies.
What doesn’t qualify: land, the building structure itself, and inventory. If a vendor is pitching you on a real estate play as a bonus depreciation strategy, get a second opinion before you sign anything.
The “placed in service” requirement is the one that trips people up every fall. Ordering equipment in November and receiving it in January 2027 doesn’t get you a 2026 deduction. The asset has to be operational, not just on order. If you’re planning a major purchase, start the process now. Lead times on industrial equipment, commercial vehicles, and specialized machinery can easily run 8 to 16 weeks.
Bonus Depreciation vs. Section 179: Which One to Use
Helpful resource: Profit First by Mike Michalowicz is a top-rated option for this. (As an Amazon Associate this site earns from qualifying purchases.)
Both are available in 2026, and the interaction between them matters. Section 179 lets you expense the full cost of qualifying property in the year it’s placed in service, but it has caps and phase-outs. Bonus depreciation has no dollar limit and no phase-out threshold.
Here’s how they compare side by side:
| Feature | Section 179 | Bonus Depreciation |
|---|---|---|
| 2026 deduction rate | 100% (up to limit) | 100% |
| Annual spending cap | $6.65M on equipment | None |
| Phase-out threshold | Begins at $2.66M in purchases | None |
| Can create a tax loss? | No | Yes |
| New and used property? | Both | Both |
| State conformity | Generally higher | Often limited |
The critical difference: Section 179 can’t take your taxable income below zero. Bonus depreciation can. If you have a high-revenue year and want to generate a net operating loss that carries into future years, bonus depreciation is the mechanism. If you just want to zero out your taxable income without creating a loss, Section 179 is cleaner, and it often has better state tax treatment.
Most small businesses with straightforward situations will use a combination, applying Section 179 first and then bonus depreciation on any remaining basis. Your CPA should be running this calculation, not guessing.
The State Conformity Problem Nobody Talks About
Federal law says 100% bonus depreciation. Your state may disagree.
This is the hidden gotcha in OBBBA coverage, and it catches multi-state operators constantly. States set their own conformity rules, and many do not automatically adopt federal bonus depreciation provisions. California, for example, has historically decoupled from federal bonus depreciation rules. Other states cap it, phase it differently, or require separate depreciation schedules entirely. As Warren Averett noted in their January 2026 OBBBA breakdown, businesses operating across multiple states need to verify each state’s treatment individually, because the variance is wide.
What this means practically: your federal tax savings could be real while your state tax liability is unaffected. That doesn’t make bonus depreciation a bad move. It makes it a move you should model accurately, not assume.
If you operate in a single state with strong federal conformity, this is less of an issue. If you’re in multiple states, or in a state with a known history of decoupling, get specific guidance before you make purchasing decisions based on an assumed combined tax rate.
How to Actually Execute This Before December 31
The window is real, and Q3 is already underway. Here’s the practical sequence.
First, identify what you actually need. Bonus depreciation is a great accelerant for purchases you were already going to make. It’s a poor reason to buy equipment you don’t need, because cash out the door is still cash out the door regardless of the deduction.
Second, confirm financing timelines. According to U.S. Bank’s July 2026 guidance on Section 179 and bonus depreciation, financing a qualifying purchase doesn’t disqualify it from the deduction. You can borrow to buy equipment, place it in service, and still take the full deduction in 2026. This matters for cash flow planning: the tax benefit arrives before the loan is paid off.
Third, talk to your CPA before October. Not in November when everyone is scrambling. The earlier you model the deduction against your projected 2026 taxable income, the more accurately you can size the purchase and structure it correctly.
The OBBBA made this tool permanent, but the tax year doesn’t wait. Equipment ordered today, delivered and operational before December 31, gives you a full deduction on a return you’ll file in early 2027. That’s a five-month window, and it’s already shrinking. The businesses that benefit most from this provision aren’t the ones who understand it best in theory. They’re the ones who started the paperwork in August.
