If you run or finance a manufacturing business in the U.S., Section 70301 of the “One Big Beautiful Bill” is worth your full attention. It makes 100% bonus depreciation (full expensing) permanent for qualified business property under IRC §168(k) and cleans up a handful of rules that used to create planning headaches—especially for large, long-lead builds.

Below is a practical, manufacturer-first guide to what changed, why it matters, and how to take advantage.

What Changed (plain English)

• – Permanent 100% expensing. Qualified property (generally MACRS ≤20-year property, many production assets, certain software, and qualified improvement property) can be deducted in full in the first year—no more phasedown percentages.
  
• – Long-production property certainty. The old calendar cut-offs for longer production period property and certain aircraft are removed. If it meets the definition, it’s eligible—without a race to beat sunset dates.
  
• – Self-constructed property clean-up. Timing rules tied to the now-deleted acquisition dates are removed, simplifying projects you build for yourself (common in plant expansions).
  
• – Specified plants (orchards/vines) get permanent 100% expensing too. Less relevant for most factories, but notable for integrated food & beverage producers.
  
• – One-time “reduced bonus” option for 2025 tax year. For the first taxable year ending after Jan 19, 2025 (calendar-year 2025 for most), you may elect 40% (most property) or 60% (long-production/aircraft) instead of 100%—useful if full expensing would waste losses or depress other tax attributes.
  
• – Binding contract rule remains. Eligibility hinges on property “acquired” after Jan 19, 2025, with the usual rule that a written binding contract fixes the acquisition date.

Why Manufacturers Should Care

1) Cheaper, Faster Modernization

Full expensing turns capital purchases into immediate tax shields, accelerating ROI on modernization:

• – Example: A $20M production line yields a $4.2M federal cash-tax benefit in year 1 at a 21% C-corp rate (20,000,000 × 0.21 = 4,200,000).
• – That’s cash you can redeploy into automation, robotics, quality systems, and capacity—this year, not over a decade.
  

2) Confidence to Commit to Long-Lead Projects

The date-driven sunset drama is gone for long-production property. Custom presses, furnaces, large machining centers, complex conveyors, and specialized transportation equipment often span long engineering and delivery cycles. With permanent 100% expensing and no calendar cliff:

• – You can sequence orders for operational readiness, not arbitrary tax deadlines.
• – Supply-chain disruptions are less likely to undermine the tax model for the project.
  

3) Advantage in Reshoring & Capacity Expansion

Full expensing directly improves the after-tax cost of capital, which helps business cases for reshoring/near-shoring and vertical integration (casting, coatings, components). It also narrows the gap between greenfield and brownfield projects by improving early-year cash flows.

4) Used Equipment Still Works

The TCJA-era expansion (no prior use by you, arm’s-length, etc.) means used machinery can qualify. That opens up attractive plays:

• – Asset deals / carve-outs / §338 elections in M&A can unlock immediate deductions.
• – Secondary market buys (e.g., CNCs, robots, forklifts) keep modernization rolling when OEM lead times are long.
  

5) Cleaner Accounting for Project Managers

For companies with percentage-of-completion (PCM) contracts on the construction side, the coordination rules continue to prevent bonus depreciation from distorting cost-to-complete on shorter-life assets. In practice, this keeps project reporting saner while still granting expensing for your manufacturing capex base.

What This Enables on the Factory Floor

• – Automation & Robotics: Faster payback on cobots, vision systems, and automated material handling; easier to justify safety and quality investments that don’t directly add throughput but lower defects and injuries.
• – Energy & Reliability: Immediate write-offs for high-efficiency drives, compressors, ovens, and process controls improve plant uptime and utility intensity—helpful for both margin and ESG narratives.
• – Quality & Inspection: Metrology, NDT equipment, and inline vision can be expensed Day 1, tightening process capability (Cp/Cpk) and reducing scrap.
• – Digital Ops: Servers and certain software tied to MES/SCADA, scheduling, and predictive maintenance benefit from first-year deductions, making connected factory upgrades easier to green-light.

CFO/Controller Planning Notes

• – Mind the contract date. To be “acquired after Jan 19, 2025,” ensure the binding contract is dated accordingly. Change-orders or re-papering may matter in edge cases—coordinate tax and procurement.
• – Consider the 2025 reduced-bonus election. If 100% expensing would:
  • – Push you into an NOL you can’t easily use,
  • – Reduce §199A/QBI deductions for owners of pass-throughs, or
  • – Intensify §163(j) interest-limitation pressure (because EBITDA falls with a larger year-1 deduction),
• – Then the 40%/60% election for the 2025 tax year can smooth deductions.
• – Don’t forget states. Many states decouple from federal bonus depreciation. Expect add-backs and slower state-only depreciation schedules. Build federal vs. state tax depreciation tracks in your fixed-asset system and cash-flow model.
• – Bonus vs. §179. With 100% bonus permanent, §179 is still valuable for its eligibility scope and immediate expensing of certain improvements—but watch its phase-outs and state conformity. Coordinate choices by asset class each year.
• – Project Controls. Keep procurement, engineering, and tax aligned on:
  • – In-service dates (when an asset is ready and available for its intended use),
  • – Componentization (break large lines into assets with correct class lives), and
  • – Self-constructed costs (capitalize the right indirects; bonus applies to the resulting property if it qualifies).

A Quick Checklist for Manufacturers

✅ Audit your 12–24 month capex roadmap. Flag everything with class life ≤20 years.

✅ Re-confirm contract and PO dates for major equipment to ensure “acquired after Jan 19, 2025.”

✅ Model 100% vs. 40%/60% for 2025 (calendar-year taxpayers). Pick the path that optimizes cash taxes, interest limits, and QBI.

✅ Coordinate with FP&A to capture the first-year cash benefit in your internal IRR/NPV hurdles.

✅ Map state conformity and set up depreciation books accordingly

✅ Review used-asset opportunities (auctions, carve-outs) that now carry a stronger tax shield.

✅ Strengthen fixed-asset policies (in-service criteria, component tracking, capitalization).

The Bigger Picture

Manufacturing is capital-intensive. Making full expensing permanent lowers the after-tax cost of investing in the tools that drive productivity—robots, precision machinery, and digital infrastructure. It also removes “policy risk” tied to date-driven phase-downs, giving operations leaders the confidence to commit to multi-year modernization programs.

In a world where lead times, labor availability, and quality demands are all tightening, cash today to fund capability tomorrow is a competitive advantage. This change delivers exactly that.

What changed

• – The Section 179 expensing limit (the max you can immediately deduct for qualifying business equipment instead of depreciating it) goes from $1,000,000 to $2,500,000.
• – The phase-out threshold (the point where that deduction starts shrinking, dollar-for-dollar, as you place more property in service) goes from $2,500,000 to $4,000,000.

When it applies

These new amounts apply to property placed in service in tax years beginning after December 31, 2024.
For calendar-year businesses: this means starting with your 2025 tax year.

How the phase-out works now

• – You can deduct up to $2,500,000 under §179.
• – But if your total purchases of qualifying §179 property placed in service that year exceed $4,000,000, your max §179 deduction is reduced dollar-for-dollar by the excess.
• – That means the deduction goes all the way down to $0 once your total purchases hit $6,500,000 (because $2,500,000 limit − [$6,500,000 − $4,000,000] = $0).
  

Quick examples

• – Buy $1.2M of qualifying equipment in 2025 → You can generally expense $1.2M (it’s under the $2.5M cap; still subject to the usual business-income limit).
• – Buy $4.8M in 2025 → Over the threshold by $800,000, so your §179 limit becomes $2.5M − $0.8M = $1.7M (again, still subject to the business-income limit).
• – Buy $7.0M in 2025 → Over by $3.0M; the §179 limit would be $2.5M − $3.0M = $0 (no §179 deduction).
  

Inflation indexing tweak

The new $2.5M and $4.0M figures will be indexed for inflation starting with tax years that begin in 2025, using calendar year 2024 as the base year for the calculation. (Other §179 amounts keep their existing inflation rules.)

Don’t forget the usual §179 rules still apply

The deduction can’t exceed your taxable business income for the year (excess generally carries forward).

Property must be qualifying §179 property (e.g., most tangible business equipment, certain software, some improvements to nonresidential real property).

This is separate from bonus depreciation; taxpayers typically apply §179 first, then bonus, if needed.

If you want, tell me your numbers (total qualifying purchases and business income for 2025) and I’ll run the exact §179 cap under these new rules.
