A manufacturing client called us last month with a familiar problem. His business generated $850,000 in profit this year, far more than the usual $400,000. Between a major contract and some one-time gains, he was staring at a substantial tax bill. "I need equipment, but I was planning to wait until early next year."

That conversation changed when we explained the impact of the One Big Beautiful Bill (OBBB). Thanks to legislation signed this past July, 100% bonus depreciation is now permanent for qualifying property. Instead of spreading that $200,000 equipment purchase over seven years, he could deduct the entire amount in 2025.

The tax impact was significant: a $200,000 deduction could save $64,000-$74,000. And that’s money that now stays in the business instead of going to taxes.

For business owners making strategic equipment or vehicle purchases, understanding bonus depreciation creates opportunities to accelerate deductions and reduce current-year taxes. But knowing how it works, and when to use it, makes the difference between smart tax planning and expensive timing mistakes.

The First-Year Write-Off That’s Now Permanent

Bonus depreciation allows you to deduct 100% of qualifying property's cost in the purchase year rather than spreading depreciation over multiple years. Before the OBBB, this accelerated depreciation was declining: 80% in 2023, 60% in 2024, and was scheduled to phase out by 2027. Now it's permanent at 100% for assets acquired after January 19, 2025.

What qualifies:

• New or used tangible property with a recovery period of 20 years or less
• Equipment, machinery, vehicles, computers, furniture
• Qualified improvement property (certain building improvements)
• Off-the-shelf software

What doesn't qualify:

• Real property (buildings, land)
• Property converted from personal use
• Property acquired from related parties

The critical requirement: Property must be both acquired AND placed in service during the tax year. Purchasing equipment in December but not using it until January 2026 won't qualify for 2025 bonus depreciation.

Unlike many tax provisions, bonus depreciation applies without election unless you choose to opt out. This differs from Section 179 deductions, which require active elections and have income limitations.

How Section 179 and 100 Percent Bonus Depreciation Work Together

Many business owners confuse Section 179 with bonus depreciation. Both allow immediate deductions, but they operate through different mechanisms and work together in strategic combinations.

Section 179: Elective, $2.5 million limit for 2025, cannot create business losses, limited to taxable income

Bonus depreciation: Automatic, no dollar limits, CAN create net operating losses, no income limitations

Strategic combination example:

A contractor purchases $200,000 in qualifying equipment. Section 179 expenses the first $31,300 (if it's a heavy vehicle), then bonus depreciation applies to the remaining $168,700. Result: $200,000 equipment tax deduction in year one.

The strategic question becomes: Do you want the entire deduction this year, or would spreading it over multiple years provide better tax management?

The 6,000-Pound Rule and Vehicle Considerations

Vehicle depreciation follows special rules that affect bonus depreciation strategies:

Passenger vehicles under 6,000 lbs: Cars, light trucks, and vans face luxury auto limits. For 2025, first-year depreciation is capped at $20,200, limiting bonus depreciation benefits for most passenger vehicles.

Heavy vehicles over 6,000 lbs: SUVs, trucks, and vans over 6,000 pounds gross vehicle weight receive more favorable treatment. Section 179 is limited to $31,300, but bonus depreciation can apply to remaining cost.

Business use requirements: You must use the vehicle more than 50% for business to qualify. Personal use percentage isn't deductible. This creates ongoing documentation requirements: detailed mileage logs for the vehicle's entire business life.

Placed in service requirement: The vehicle must be purchased and used for business before December 31st. You need at least one business trip before year-end.

Not Every Business Should Front-Load Deductions

Bonus depreciation makes strategic sense when you have a high-income year and need equipment regardless of tax considerations. However, the setup effort and ongoing administrative requirements deserve consideration before accelerating purchases.

When bonus depreciation provides clear advantages:

• High-income timing benefit: Remember our manufacturing client? Like him, your firm might generate $400,000 in profit during a typical year but had an exceptional year with $850,000 due to a major project completion. Accelerating planned 2026 equipment purchases into December 2025 maximizes deductions in the higher tax bracket year.
• Equipment needs align with operations: You were planning these purchases for operational reasons. The equipment increases productivity, generates revenue, or replaces aging assets. Tax benefits become a bonus, not the primary motivation.
• Strong cash flow position: The purchase doesn't strain operations or emergency reserves. You're not financing at unfavorable terms just to capture tax benefits.

When front-loading might not make sense:

• Lower current income years: If your 2025 profit is lower than expected, deductions provide less tax benefit. If you’re expecting higher profits in 2026, you might benefit more from delaying purchases.
• Administrative complexity concerns: Vehicle purchases require detailed mileage logs throughout ownership. Equipment purchases need careful tracking for potential recapture calculations. Consider whether your current systems can handle the additional record-keeping burden.
• Cash flow vs. tax savings trade-offs: A service business with seasonal cash flow could purchase $100,000 in equipment to save $32,000 in taxes, but if the purchase creates cash flow strain during slow months, the operational cost might exceed tax benefits.

>> Key Takeaway: Bonus depreciation is a timing tool for managing when you take deductions, not a method for avoiding taxes without business justification.

The Tax Bill That Comes Later

Most business owners overlook depreciation recapture when planning bonus depreciation strategies. When you sell depreciated property for more than its adjusted basis, you'll "recapture" previous deductions as ordinary income.

How recapture works:

Purchase equipment for $80,000, take $80,000 bonus depreciation (saving $25,600 at 32% rate), then sell three years later for $50,000. You'll recapture $50,000 as ordinary income, owing $16,000 in taxes. Net benefit: You deferred $9,600 in taxes for three years.

Strategic implications:

• Bonus depreciation defers taxes rather than eliminating them
• The time value of money still makes deferral valuable
• Works best for equipment you'll use until depreciated or worthless
• Documentation requirements continue for the asset's entire business life

For vehicles, if business use drops below 50% in later years, you may need to recapture excess depreciation taken. This makes maintaining detailed mileage logs crucial throughout ownership, not just during the purchase year.

Your Action Plan for the Next Few Weeks

With 23 days until year-end, strategic equipment purchases require immediate evaluation:

Week 1 (by December 12th):

• Review equipment you planned to purchase in Q1 2026
• Calculate tax benefit of accelerating purchases (profit × tax rate × equipment cost)
• Verify cash flow capacity without straining operations
• Get delivery quotes and timelines from vendors

Week 2-3 (by December 28th):

• Make purchase decisions based on business need first, tax benefits second
• Ensure delivery AND placement in service before December 31st
• For vehicles: Take possession and complete at least one business trip
• Document everything: purchase invoices, delivery receipts, first business use

Essential documentation:

• Purchase invoice with delivery date
• Proof equipment was ready and available for business use in 2025
• For vehicles: Mileage log starting on first business use
• Photos showing equipment in business location or active use

Coordinate with your tax professional:

• Confirm specific equipment qualifies for bonus depreciation
• Model optimal combination of Section 179 and bonus depreciation
• Calculate projected tax impact before committing to purchases

Strategic Acceleration vs. Panic Buying

Bonus depreciation's permanent status removes the urgency of phase-down deadlines, which should improve decision-making quality. The strategic question isn't "Can I use bonus depreciation?" but "Should I use it this year?"

Consider these factors:

• Is this equipment you need regardless of tax benefits?
• Is 2025 a high-income year where deductions provide maximum value?
• Can you afford the purchase without creating cash flow problems?
• Does the equipment improve operations, productivity, or revenue generation?
• Can your current systems handle the additional documentation requirements?

If you're buying for tax deductions alone, you're spending $1.00 to save $0.32-$0.37 in taxes. That's not strategy, it's expensive decision-making driven by tax avoidance rather than business growth.

At Better Bookkeeping, we help business owners model these scenarios before making year-end equipment decisions. The goal is finding purchases that make operational sense while providing strategic tax benefits.

Beyond bonus depreciation, consider exploring S-Corporation elections for self-employment tax savings, retirement plan contributions that reduce current taxes, and year-end tax planning strategies that complement equipment purchases.

The most effective tax strategies combine multiple approaches rather than relying on single tactics like accelerated depreciation. Strategic business owners evaluate the complete picture of available deductions and timing opportunities.

Not sure if accelerating equipment purchases aligns with your tax situation? Schedule a consultation to review your specific circumstances and model the impact before December 31st.
