🚀 100% Bonus Depreciation Is Now Permanent — A Powerful 2025 Tax Strategy for Small Business Owners
Starting in 2025, the depreciation rules for business property change in a big way. Under prior law, Bonus Depreciation was scheduled to phase down — 80% in 2023, 60% in 2024, 40% in 2025, and then gradually disappear.
With the new law, that phase-down schedule is eliminated and 100% bonus depreciation is restored and made permanent for qualifying property.
In practical terms, this means that when you buy equipment, machinery, computers, vehicles, or other eligible assets, you no longer have to spread deductions over many years. You can expense 100% of the cost in the first year.

1️⃣ What Changed with 100% Bonus Depreciation?
Before the 2025 changes, bonus depreciation was on a fading schedule and was expected to disappear over time. Under the new rules, that phase-down is removed and qualifying property is again eligible for a full 100% write-off in the first year.
- Effective date: Applies to property acquired and placed in service after January 19, 2025.
- Deduction amount: 100% of the acquisition cost may be claimed as bonus depreciation in the first year.
- Duration: The 100% rate is not temporary — current law treats it as a permanent rule unless Congress changes it again.
- Who can use it: Sole proprietors, partnerships, S corporations, and C corporations can all benefit.
In other words, after 2025 “when” and “how” you buy business assets becomes a key driver of your taxable income and cash flow.
2️⃣ What Counts as Qualified Property?
The 100% bonus depreciation rules only apply to Qualified Property as defined in the Internal Revenue Code. In day-to-day practice, you can think of it this way:
- Property with a recovery period of 20 years or less
(machinery, equipment, computers, office furniture, certain land improvements, etc.) - Business vehicles
(subject to separate luxury auto limitations for passenger vehicles) - Qualified Improvement Property (QIP)
— certain interior improvements to nonresidential buildings - Some film, TV, and live theatrical production costs
- Certain utility, power, and communications infrastructure assets
Since 2017, used property can also qualify for bonus depreciation if specific conditions are met. At a minimum, you need to confirm that:
- The property was not previously used by the same taxpayer.
- The property was not acquired from a related party (family member, entity under common control, etc.).
- The property is actually placed in service for business use after acquisition.
A practical way to remember this is: “New or used, as long as it’s new to your business and not from a related party, it can often qualify.”
3️⃣ Section 179 vs Bonus Depreciation — How to Choose
Many taxpayers view Section 179 and bonus depreciation as identical because both can provide a first-year deduction. In reality, the two provisions work very differently and can produce very different tax results.
With 100% bonus depreciation now permanent, it is more important than ever to understand when to rely on Section 179 and when to lean on bonus depreciation.
The table below summarizes how EA and CPA practitioners typically compare the two when advising small business owners:
| Item | Section 179 | Bonus Depreciation | Practical Takeaway |
|---|---|---|---|
| Deduction rate | Up to 100% of the cost | 100% of the cost (permanent from 2025 forward) | Both can provide a full first-year write-off. |
| Annual dollar limit |
Subject to an annual maximum deduction limit (around $1.29M for 2025, indexed for inflation) | No statutory dollar limit |
For high-dollar equipment, trucks, or manufacturing assets, bonus depreciation is far more powerful. |
| Taxable income limitation |
Cannot exceed the taxpayer’s taxable business income for the year. Section 179 alone cannot create a Net Operating Loss (NOL). |
No taxable income limitation. Bonus depreciation can reduce income below zero and create an NOL. |
In start-up years or heavy investment years, bonus depreciation is usually the primary tool if you want to create or increase an NOL. |
| Overall investment cap |
If total equipment purchases exceed a phase-out threshold, Section 179 deduction is reduced and can eventually be eliminated. | No overall investment cap. |
For industries with high capital expenditures (trucking, construction, manufacturing), bonus depreciation is often essential. |
| Used property | Generally allowed. | Allowed, as long as it is not previously used by you and not from a related party. | Both can work for used equipment, but bonus rules are more technical. |
| State tax conformity |
Many states do not fully conform to the federal Section 179 rules or they apply much lower limits, which may require add-backs on the state return. |
A large number of states follow federal bonus depreciation rules or require fewer adjustments. |
If you want simpler state returns, bonus depreciation is often the cleaner choice, but you must still check each state’s conformity rules. |
🔍 Summary: How practitioners really choose between the two
- High-dollar assets (trucks, heavy equipment, large machinery)
→ Bonus depreciation is usually the first choice. - Start-ups and businesses planning to use NOLs
→ Bonus depreciation is more flexible because it is not limited by taxable income. - Owners who want very simple state income tax filings
→ Bonus depreciation often produces fewer state-level adjustments. - Profitable, smaller operations with modest equipment costs
→ Section 179 still works well, especially when you want tighter control over the deduction.
📝 Order of application under the tax rules
When a taxpayer is eligible to claim both Section 179 and bonus depreciation on the same property, the general order is:
- Step 1 — Apply Section 179 to the extent you elect and are allowed for the year.
- Step 2 — Apply 100% bonus depreciation to any remaining depreciable basis in that property.
- Step 3 — Apply regular MACRS depreciation to whatever basis, if any, is left.
In practice, you can think of Section 179 as an optional, elective tool and bonus depreciation as the automatic “turbo boost” that follows unless you elect out.
• Even for small businesses, high-priced vehicles or equipment can quickly hit the Section 179 limit, making bonus depreciation the more powerful tool.
• Because bonus depreciation can create Net Operating Losses, it is especially valuable in start-up years and capital-intensive industries like trucking, construction, and manufacturing.
• Always verify how your state conforms to federal rules before finalizing a strategy. The federal result may look great, but state add-backs can change the overall picture.
4️⃣ Five Practical Tax Strategies for Small Businesses
- 1. Time major equipment purchases for after 2025
If you are planning a large upgrade in machinery or vehicles, consider scheduling purchases so they qualify for the permanent 100% bonus depreciation window. - 2. Treat used equipment as a planning opportunity
Used trucks or machinery can qualify if the seller is not related and you did not previously use the asset. Compare the total ROI of a used asset with bonus depreciation versus a new one with similar tax treatment. - 3. Use bonus depreciation to support new locations and build-outs
When opening a café, restaurant, or franchise, you can often expense most of your initial CAPEX — espresso machines, refrigerators, POS systems, furniture, and certain interior improvements — in year one, preserving precious cash. - 4. Coordinate entity structure with asset planning
S corporations and C corporations can both use bonus depreciation, but the impact on owners’ personal returns can differ. When you are considering an entity change, look at when large asset purchases will occur and plan accordingly. - 5. Intentionally create NOLs for later years
Some businesses purposely “over-deduct” in a year of heavy investment to generate an NOL that can offset future income when the business is more profitable. Bonus depreciation is a key tool for this type of long-term planning.
5️⃣ Real-World Examples of First-Year Savings
• A trucking LLC buys two heavy-duty trucks in March 2025, each costing $90,000. Total investment: $180,000.
• Under regular 5-year MACRS alone, only a small portion would be deductible in year one.
• Under the new rules, both trucks are eligible for 100% bonus depreciation in 2025.
▶ If the business would otherwise have $200,000 of taxable income:
→ Claiming $180,000 of bonus depreciation reduces taxable income to $20,000.
→ The tax savings in that first year can be substantial and free up cash for fuel, drivers, and maintenance.
Example 2 – New coffee shop build-out
• A new coffee shop invests $80,000 in espresso machines, refrigerators, POS systems, seating, and other eligible equipment.
• Most of these assets have recovery periods of 7 years or less and qualify for bonus depreciation.
• With 100% bonus depreciation, the owner may be able to expense the full $80,000 in the first year.
• Even if sales are modest in year one, the ability to wipe out taxable income helps the owner reinvest in marketing, staff training, and cash reserves.
6️⃣ EA Practice Notes and Common Pitfalls
• Even when you claim 100% bonus depreciation, the asset still exists on the books. You may need a Schedule M-1 or M-3 adjustment to reconcile book and tax depreciation for entities.
• Business vehicles qualify for bonus depreciation, but luxury auto limits still apply to many passenger vehicles. Do not assume you can write off the entire purchase price of a high-end SUV in one year.
• When you dispose of property that has been fully expensed, you may face depreciation recapture. Future gain can be taxed at ordinary income rates up to the amount of prior depreciation.
• The IRS frequently examines used-property purchases, related-party transactions, and mixed business/personal use. Keep strong documentation: purchase agreements, mileage logs, usage records, and business justifications.

9️⃣ Google-Friendly Q&A
Q1. What is the bonus depreciation rate for 2025?
A. For qualifying property placed in service after January 19, 2025, the bonus depreciation rate is 100% of the acquisition cost. The phase-down schedule that would have reduced the rate has been eliminated under current law.
Q2. Can I claim 100% bonus depreciation on used equipment or used trucks?
A. In many cases, yes. Used property can qualify as long as it is new to your business, was not previously used by you, and was not purchased from a related party. The property must also be placed in service for a valid business purpose.
Q3. Does every business vehicle qualify for a full 100% write-off?
A. Not automatically. Business vehicles may qualify for bonus depreciation, but passenger vehicles are subject to luxury auto limits. Heavy trucks and certain SUVs may get more favorable treatment, so it is important to check the specific rules before you buy.
