Hyperscale data center cost segregation
Engineering-method cost segregation for $50M+ data center investments. Published floor from $42,995 ($50–60M), $54,995 at $60–100M; engagements above $100M campus basis scoped by proposal. Named credentialed engineering partners brought in per engagement; §481(a) lookback workpaper rigor sized for hyperscale dollar volumes.
Hyperscale cost segregation in one paragraph
A $500M hyperscale facility typically reclassifies 43–65% of basis into accelerated 5/15-year MACRS — UPS systems, precision cooling, electrical distribution, fire suppression, security infrastructure — out of the default 39-year building-shell treatment. Combined with 100% bonus depreciation restored permanently under OBBBA (PIS after 1/19/2025), year-1 federal tax savings on hyperscale builds routinely exceed nine figures at corporate rates. The framework is identical to any commercial cost-seg engagement (Rev. Proc. 87-56 component classification, industry-standard 2026 construction cost data, IRS Pub 5653 examiner framework); the engineering depth, documentation rigor, and credentialing requirements scale with the dollar volume.
Hyperscale component allocation
Indicative ranges for a typical hyperscale build. Actual depends on facility tier rating, capex composition across acquisition + expansion phases, cooling architecture (air vs. liquid vs. immersion), and redundancy topology (N+1 vs. 2N vs. 2N+1).
Categories above mirror the framework documented in IRS Cost Segregation Audit Techniques Guide (Pub 5653) and asset-class table at Rev. Proc. 87-56. Per-facility engineering analysis refines allocation by component.
Worked example: $500M hyperscale campus
Illustrative; actual depends on basis composition, ownership structure (REIT vs. operating company), capex phasing across the facility lifecycle, and corporate tax position when the deduction lands.
- Facility
- Hyperscale campus, ~100MW IT load, Tier III-rated, single-tenant
- Depreciable basis
- $500,000,000
- Illustrative engineering-estimated reclassification
- 50% = $250,000,000 into accelerated MACRS
- Year-1 deduction
- ~$200,000,000 (100% OBBBA bonus on 5/15-year property)
- Estimated federal tax savings
- ~$42,000,000 at 21% corporate rate
- Engagement
- From $42,995 published floor ($50–60M), $54,995 at $60–100M; by-proposal above $100M campus basis, scoped against facility documentation + customer deliverable expectations
Assumes 21% federal corporate marginal tax rate. REIT-owned facilities and pass-through structures have different effective rates; state conformity to §168(k) varies. Verify with tax counsel.
How a hyperscale engagement works
- Proposal intake. Send the closing statement / construction contract, capex schedule across acquisition + expansion phases, equipment lists (UPS, cooling plant, generators, electrical distribution, security), facility-rating documentation (Uptime Institute, ISO), and as-built drawings. We'll respond with a written proposal covering scope, timeline, named engineering partners, and fee.
- Engineering scoping. For each engagement we coordinate the right named credentialed engineering partners — CCSP, ASHRAE TC 9.9, specialty MEP — based on facility tier rating and customer deliverable expectations. The partners author and sign the cover; we handle the cost-seg analysis, industry-standard 2026 construction cost data basis allocation, Rev. Proc. 87-56 component mapping, and §481(a) workpaper construction.
- On-site walkthrough typically routine at hyperscale dollar volumes. The named engineering partner brought in for the engagement verifies cooling architecture, redundancy topology, electrical distribution, and any post-acquisition capex tranches.
- Report delivery. Report with component-level basis allocation, MACRS classification per Rev. Proc. 87-56, cost-source citations, audit-defense methodology mapped to the 13 IRS Pub 5653 quality elements, §481(a) workpaper pack if applicable, quality checks, and named partner engineer signature on the cover. Timeline calibrated to facility complexity; pre-PIS engagements often deliver same-day preliminary modeling.
- Audit documentation included, with support for the life of the study — workpaper exhibits, classification rationale per component, ATG 13-element methodology narrative, and written answers to your CPA's technical questions at no charge.
