When to keep Duffy + Duffy Cost Segregation on your shortlist

Keep Duffy + Duffy on your shortlist for an engineering-based commercial study, including a new or existing building or a LEED-certified project. Its website describes a team with accounting, engineering and estimating experience.

Read the provider’s own description. Do not treat a commercial engineering proposal as interchangeable with a residential self-serve report. Confirm property eligibility, investigation, accountant questions and any related energy or construction analysis.

A situation worth comparing

Suppose you completed an energy-efficient office building and already have a CPA handling the return. Compare the engineering study, treatment of construction records and any separately scoped energy-related work.

Keep the provider whose proposal addresses the building’s technical details and your preparer’s required documentation. Compare the study fee and any additional specialty work separately.

Compare total cost before switching

Duffy + Duffy Cost Segregation pricing and quote checklist. A software report, an engineering study and a tax advisory engagement buy different work. Compare inspection method, report detail, travel, CPA questions, support and any separately priced Form 3115 or return work.

Request a property-specific study quote and identify the report deliverables, preparer handoff and audit-support terms. Confirm any Form 3115 preparation and return filing separately; a study fee is not an all-inclusive tax engagement.

Ask for a proposal you can compare

  • What inspection and engineering investigation are included for this building?
  • How are construction records and building components documented?
  • Who answers my CPA’s questions and supplies the final schedules?
  • Are energy-related analysis, forms or tax-return services separately contracted?

Give each firm the same property address, square footage, closing statement, placed-in-service date, improvement records and existing depreciation schedules. Identify the owner entity, return preparer and deadline. Request a written scope for inspection, engineering analysis, report schedules, support and separately billed implementation. Send sensitive records through the firm’s secure intake process.
