## 1. What CaliberSeg Is

CaliberSeg is a U.S. cost segregation study provider serving commercial and investment real estate owners. A cost segregation study is an engineering-based tax analysis that reclassifies building components from long-life depreciation schedules (27.5-year residential or 39-year nonresidential) into shorter-life MACRS categories (5-year, 7-year, and 15-year), which — under current federal law — are fully eligible for 100% bonus depreciation in the first year.

Every CaliberSeg study:
- Follows all 13 required elements of the IRS Cost Segregation Audit Techniques Guide (Publication 5653)
- Is prepared using a proprietary engineering methodology with a 197-line-item cost reference database
- Is reviewed and signed by a degreed engineer (BSCE / BSME / BSIE, or PE) before delivery
- Includes full legal citations (IRC §168, §1245, §1250, Rev. Proc. 87-56, ATG section references, and relevant Tax Court precedent)
- Is delivered as a CPA-ready PDF within 5 business days of complete intake

## 2. Methodology

### Step 1 — Property Intake
Customer completes an online questionnaire describing construction type, finishes, square footage, systems, year built, purchase details, renovations, and property use. Estimated completion time: 10 minutes.

### Step 2 — Evidence Collection
Customer uploads:
- Closing statement (HUD-1, ALTA settlement statement, or equivalent) — required
- Exterior photos (minimum 4, one per side) — required
- Interior photos (minimum 10, covering kitchens, bathrooms, HVAC, electrical, flooring, specialty features) — required
- County tax assessment — recommended
- Renovation receipts — if applicable
- Blueprints — optional
- Prior depreciation schedule — required only for Lookback studies

Files upload directly to our secure cloud storage via presigned URLs.

### Step 3 — Component Classification
A deterministic, multi-step engineering analysis:

1. **Basis allocation** — purchase price divided between land (non-depreciable) and improvements (depreciable basis).
2. **Component identification** — building components enumerated by system: structural, HVAC, electrical, plumbing, flooring, ceilings, millwork, fixtures, site improvements, specialty.
3. **Cost assignment** — each component priced against our internal cost reference database (197 entries sourced primarily from Craftsman National Construction Estimator 2025, adjusted for the property's U.S. Census Division regional cost multiplier).
4. **MACRS classification** — each component assigned to 5-year, 7-year, 15-year, 27.5-year, or 39-year life per Rev. Proc. 87-56 asset classes and ATG section guidance.
5. **Reconciliation** — total allocated cost reconciled to purchase price within ±1%.
6. **Benchmark validation** — aggregate percentages validated against property-type benchmarks (e.g., multifamily: ~12.5% 5-year, 4% 7-year, 10% 15-year).

### Step 4 — Engineer Review
A degreed engineer reviews every classification, inspects flagged items (low-confidence components, large dollar reclassifications, reconciliation deltas), examines uploaded photos against the component schedule, resolves judgment calls, and signs the final report. Engineer overrides are logged with a reason in the classification trace.

### Step 5 — Report Generation
PDF delivered to customer portal containing:
- Executive summary with total savings estimate
- Asset classification schedule (every component, cost, MACRS life, IRC section)
- Photographic evidence linked to each classification
- Cost reconciliation to the dollar
- 10-year depreciation projection
- Full legal citations and engineer signature page
- Verification code for third-party validation (via /verify)

## 6. Comprehensive FAQ

### General

**Q: What exactly is a cost segregation study?**
A: An engineering-based tax analysis that identifies building components eligible for shorter depreciation recovery periods (5, 7, or 15 years) instead of the standard 27.5-year (residential) or 39-year (commercial) schedule. The result is significantly accelerated depreciation deductions in the early years of ownership.

**Q: Who benefits most from a cost segregation study?**
A: Owners of investment or business-use real estate with a depreciable basis above roughly $250,000 who have a current tax liability (or passive income to offset, or qualify for real estate professional status). Owners who recently purchased, constructed, or significantly renovated property see the largest benefit.

**Q: Is it worth it for residential rentals under $500,000?**
A: Usually yes for short-term rentals because of the higher 5-year component mix (typically 15-18% of basis). For long-term single-family rentals under $400,000, the math gets tighter — our free calculator will tell you immediately.

### Tax Mechanics

**Q: What is 100% bonus depreciation?**
A: The ability to deduct the full cost of qualified 5-, 7-, and 15-year property in the year placed in service, rather than spreading it over the recovery period. Permanently reinstated by the One Big Beautiful Bill Act (signed July 4, 2025) for property placed in service on or after January 20, 2025.

**Q: What's the difference between Section 179 and bonus depreciation?**
A: Both allow immediate expensing. Section 179 has a 2025 cap ($1.22M) and phase-out threshold, and cannot create a net loss. Bonus depreciation has no dollar cap, can create losses, and applies automatically unless elected out. For cost segregation, bonus depreciation is almost always the preferred mechanism.

**Q: What happens to passive activity loss rules?**
A: Losses from rental real estate are generally passive. They can offset passive income or carry forward. If you qualify as a Real Estate Professional (750 hours + material participation), losses become non-passive. Short-term rentals with average stays under 7 days are not classified as rental activities under §469 — material participation alone is sufficient.

**Q: Does cost segregation affect capital gains when I sell?**
A: Yes — depreciation recapture applies. §1245 property (5/7-year) is recaptured at ordinary rates. §1250 property (15-year and structural) is recaptured at a maximum of 25%. Even with recapture, the time value of money almost always makes cost segregation beneficial. 1031 exchanges can defer recapture indefinitely.

### Process & Timing

**Q: How long does a study take?**
A: 5 business days from the moment intake (questionnaire + uploads) is complete. 48-hour rush is available for $995.

**Q: Do you need to visit my property?**
A: No. Photos, closing statement, and (optionally) blueprints and tax assessments are sufficient. This is explicitly permitted by the IRS ATG and is how modern cost segregation is performed by firms of all sizes.

**Q: When should I get the study done?**
A: Ideally in the same tax year as the acquisition or renovation. But Lookback studies (with Form 3115) can capture missed depreciation from any prior year in a single catch-up deduction.

### Pricing & ROI

**Q: Why are your prices fixed when other firms quote?**
A: Because the work scales predictably with property type and value. We've built the methodology and data to price confidently. Transparent pricing removes the 2-4 week proposal cycle that legacy firms impose.

**Q: What's the typical ROI?**
A: 5x to 15x the study cost in first-year tax savings, depending on property value, type, and marginal tax rate. At the higher end (STR, restaurant, hotel in a 37% bracket), ROI can exceed 20x.

### Legal Defensibility

**Q: Will this survive an IRS audit?**
A: Cost segregation studies properly prepared to ATG standards are audit-defensible. CaliberSeg reports include full legal citations, asset class references from Rev. Proc. 87-56, photographic evidence for each classification, and engineer certification. We also offer 3-year Audit Defense as an optional add-on.

**Q: Are your engineers really qualified?**
A: Yes. All studies are reviewed by degreed engineers (BSCE, BSME, or BSIE), Professional Engineers (PE), or certified cost estimators (AACE, ASPE). The IRS ATG requires "appropriate qualifications" — there is no single required license. Our engineer sign-off is on the signature page of every study with credentials listed.

**Q: Can my CPA rely on your report?**
A: Yes. That's the primary deliverable. The PDF includes MACRS schedules ready to drop into Form 4562, a Form 3115 worksheet for lookback studies, and a verification code your CPA can use at /verify to confirm authenticity. Our optional CPA Coordination add-on provides direct communication with your CPA for $395.

### Form 3115 / Lookback

**Q: I bought property 3 years ago. Can I still do this?**
A: Yes. A Lookback Study calculates the depreciation you should have been taking and captures the entire cumulative catch-up via a 481(a) adjustment on Form 3115 — in the current tax year, no amended returns needed.

**Q: Is there a limit on how far back the lookback can go?**
A: No statutory limit. You can go back to the year the property was placed in service. IRS permission under Rev. Proc. 2015-13 is automatic for this type of accounting method change.

### Add-Ons

**Q: What's included in Audit Defense?**
A: If the IRS audits the return containing your CaliberSeg study, we supply supporting documentation, technical review, and direct correspondence with the examining agent for 3 years from the report date. Does not cover issues unrelated to the depreciation schedule.
