The "Triple-Dip" Renovation Strategy

Most business owners miss this: When you renovate your building, you can actually deduct MORE than you spend—sometimes in the same year.

How? By combining three tax strategies:

  1. Write off the old stuff you're replacing
  2. Accelerate depreciation on the new stuff
  3. Take 100% bonus depreciation immediately

Real example: $500K renovation → $425K in year-one deductions → $157K tax savings (at 37% rate)

That makes the renovation cost, after taxes, only $343K. Let me show you exactly how this works.


Author’s note (Sam Young, EA): I’ve engineered “triple‑dip” plans on office, restaurant, and retail renovations—figures here mirror what underwriters and auditors actually accept.


The Three Strategies Explained

Strategy #1: Partial Asset Disposition (PAD) - Write Off the Old

What it is: When you replace building components, write off the remaining value of the old ones immediately.

Example: You're replacing a 10-year-old HVAC system that originally cost $100K. After 10 years of depreciation, it still has $65K of value left on your books.

Normal approach: Keep depreciating that $65K over the next 29 years.
PAD approach: Write off the full $65K this year.

Strategy #2: Cost Segregation - Accelerate the New

What it is: Break down your renovation costs to identify what can be written off faster.

Example: Your $500K renovation includes:

  • HVAC, electrical, lighting: $300K (can be written off in 5-15 years)
  • Structural work: $200K (must be written off over 39 years)

A cost segregation study identifies which is which.

Strategy #3: 100% Bonus Depreciation - Deduct It Now

What it is: Take the components that qualify for faster depreciation and write off 100% immediately.

Example: That $300K in HVAC/electrical/lighting from above? With bonus depreciation (made permanent by the One Big Beautiful Bill Act), you deduct the entire $300K in year one.


The "Triple Dip": Putting It All Together

Your $500K office renovation:

Step 1 - PAD: Write off old components

  • Old HVAC, electrical, flooring (still on your books): $125K
  • Immediate deduction: $125K

Step 2 - Cost Seg: Identify fast-depreciation items

  • New HVAC, electrical, flooring, lighting: $300K
  • Structural improvements: $200K

Step 3 - Bonus: Write off qualifying items immediately

  • $300K × 100% bonus depreciation
  • Immediate deduction: $300K

Total year-one deductions: $425K on a $500K renovation

Tax savings: $425K × 37% = $157,250

Net cost after tax: $500K - $157K = $343K

You just made your renovation 31% cheaper through tax savings.


When to Do the Cost Segregation Study

Best: Before renovation starts

  • Identify what you'll be removing (for PAD)
  • Plan the renovation around tax benefits
  • Get maximum documentation

Good: During renovation

  • Document components as you remove them
  • Track costs in real-time
  • Easier to prove everything

Still works: After renovation

  • Can still be done via Form 3115
  • Harder to reconstruct details
  • Better than nothing!

Real Examples: Different Business Types

Restaurant ($350K Renovation)

The work: Dining room refresh, new kitchen equipment, bar renovation

The breakdown:

  • Remove old equipment (PAD): $80K deduction
  • New 5-year property: $210K × 100% bonus = $210K deduction
  • QIP improvements: $60K × 100% bonus = $60K deduction
  • Total deduction: $350K

Tax savings: $350K × 35% = $122,500

Office Building ($800K Renovation)

The work: New HVAC, lighting, flooring, bathroom upgrades

The breakdown:

  • Remove old systems (PAD): $175K
  • New components (5-15 year): $520K
  • Structural (39-year): $280K
  • Eligible for immediate deduction: $695K

Tax savings: $695K × 37% = $257,150

Retail Store ($600K Buildout)

The work: Complete store renovation, new fixtures, lighting, POS

The breakdown:

  • Old fixtures (PAD): $25K
  • Tenant improvements: $425K
  • Everything qualifies for bonus
  • Total deduction: $450K

Tax savings: $450K × 35% = $157,500


Your Implementation Checklist

Before You Start Renovating

✓ Hire a cost segregation specialist
✓ Identify what you're replacing (for PAD)
✓ Get documentation of existing components
✓ Plan renovation timing
✓ Talk to your CPA about the strategy

During Renovation

✓ Take photos of components before removing them
✓ Track costs separately (HVAC separate from painting, etc.)
✓ Save all contractor invoices
✓ Document when each component is "placed in service"
✓ Keep a renovation journal with dates

After Renovation

✓ Give cost seg report to your CPA
✓ File Form 3115 (if first-time PAD election)
✓ File Form 4562 (for bonus depreciation)
✓ Update your fixed asset schedule
✓ Keep all documentation for 7+ years


Common Mistakes

Not getting a cost seg study - Leaving money on the table
Forgetting about the old components - Missing PAD deductions
Poor documentation - Can't defend it in an audit
Doing it yourself - Almost always misses opportunities


Common Questions

Q: Can I do this myself without hiring professionals?

A: Not recommended. A cost seg study costs $5K-$15K but typically generates $100K-$500K in deductions. The ROI is 10-50x. DIY usually misses opportunities and creates audit risk.

Q: What if I already renovated last year?

A: You can still claim the benefits retroactively by filing Form 3115 with your tax return. Talk to your CPA about "catch-up depreciation."

Q: Does this work for residential rental properties?

A: Yes! Cost segregation and PAD work for both commercial and residential rental properties.

Q: How long do I have to make the PAD election?

A: You should file it with your tax return for the year you removed the components. Late elections are possible but more complex.

Q: Is this legal and audit-safe?

A: Yes, when done correctly with professional engineering studies. These are legitimate IRS-approved strategies. Just keep good documentation.


Ready to Save on Your Next Renovation?

Your action plan:

  1. Planning a renovation? Call a cost segregation specialist BEFORE you start
  2. Already renovating? Document everything and get a cost seg study now
  3. Already finished? You might still be able to claim retroactive benefits

The bottom line: These three strategies combined can cut your renovation's after-tax cost by 30-50%. That's real money back in your business.
