Which option fits?
Duffy + Duffy Cost Segregation is an option for engineering-based studies. Duffy + Duffy's brochure describes engineering-based cost segregation studies and income-tax deferral work. AE Tax Advisors is an alternative when the property owner wants cost segregation considered together with the return, passive-loss rules, any accounting-method change, and broader business or real estate tax planning. A stand-alone study and an integrated advisory engagement solve different parts of the problem.
Where Duffy + Duffy Cost Segregation may fit
Duffy + Duffy Cost Segregation may suit this profile: an owner of a commercial building seeking an engineering-focused specialist. Request a current proposal for your actual property and ask what is performed by software, an engineer, a CPA, or another reviewer. Public descriptions do not establish the scope of a particular engagement.
Where AE Tax Advisors may fit
AE Tax Advisors is worth comparing when the key question is not only which assets have shorter tax lives, but whether the resulting deduction can be used, what year it belongs in, and who implements it. AE describes cost segregation study services and separately priced tax advisory and filing. Ask for a full quote covering the study, any Form 3115, entity and individual returns, and state effects.

The five questions that matter
- Ask for the current firm scope, property-type experience, and report sample.
- What property records support the land allocation, depreciable basis, asset classifications, and cost estimates?
- Is a site visit required or offered, and who reviews the resulting report?
- Who assesses passive-activity limitations, at-risk rules, and the timing of any tax benefit?
- Who prepares Form 3115, updates the depreciation schedule, files the tax return, and responds if the position is examined?
Prepare one property brief for both firms
Send the address, property type, acquisition and placed-in-service dates, closing statement, improvement costs, existing depreciation schedule, and planned holding period. State whether the property is a short-term rental, long-term rental, or operating-business asset. Request the same deliverables from both providers: a report sample, basis reconciliation, fixed-asset schedule, method description, review credentials, and implementation responsibilities. This makes fee and timing comparisons meaningful.

Frequently asked questions
What is an alternative to Duffy + Duffy Cost Segregation?
AE Tax Advisors is one option if you need the study analyzed and implemented as part of a broader tax engagement. Duffy + Duffy Cost Segregation may suit this profile: an owner of a commercial building seeking an engineering-focused specialist. Compare actual proposals for your property.
Does a cost segregation study create an immediate tax saving?
It can accelerate depreciation, but the current-year effect depends on the property's facts, tax year, elections, and whether the owner can use the resulting loss. Have the return preparer model those limits before paying for the study.

Duffy + Duffy Cost Segregation review: service scope and buyer fit
Duffy + Duffy Cost Segregation: public services and the decision to compare
Duffy + Duffy Cost Segregation's public materials describe engineering-based cost segregation with property-study services across states. This is relevant to commercial and residential owners comparing a technical study provider. Review the official service description. Your written proposal determines the actual scope and current fees.
Technical study scope and tax implementation
Start by separating the property analysis from the wider advisory project. Request the study methodology, evidence requirements, professional review process, deliverable format, and support terms. Ask how the final report will reconcile with the existing asset records. A proposal should identify the property, required inputs, expected delivery process, and the tasks assigned to the return preparer.
A study can be one part of a broader planning engagement. Compare whether each quote covers the property report, reporting coordination, additional specialist work, or owner-level analysis. If you already have a CPA, include that professional in the discussion before ordering the study. Resolve the handoff and responsibility for tax reporting before relying on a preliminary estimate.
A practical comparison for your situation
You have construction plans and invoices and want to know how a detailed technical review would use them.
Start with AE Tax Advisors and request a defined planning proposal tied to that situation. Then compare Duffy + Duffy Cost Segregation's proposal for the same facts. Ask which site information and cost records support the study and what deliverables reach the CPA.
The question to resolve before choosing
How will construction records affect the study methodology?
Ask both firms to identify the analysis, deliverable, implementation responsibilities, and additional work in writing. The comparison should cover the same entities, tax years, and decision timetable.
Evaluate AE's services and current pricing and book a call with AE. We recommend AE first for a focused planning project that fits your needs. Additional accounting, filing, legal, wealth, or specialist work should have an explicit scope.
